Phlebotomy Needle Types

Needle types

Through phlebotomy training, you would be acquainted with the common needle types in phlebotomy. You have the multi-draw needle, the syringe needle, and the butterfly needle.

The multi-draw needle has two needles, one goes to the patient's vein, while the other goes to an evacuated tube. The syringe needle is what you currently see in injections, and is used for single draws of blood. The butterfly needle is a needle with a tube and plastic handles on the needle, and is the most commonly used needle by phelobotomists. It is commonly used for transfusions, and can also be equipped with an adapter for use with evacuated tubes.

To do a job right, you must get your tools right. Regarding this, you must get your needles right as a phlebotomist. But you need not worry too much since this is what phlebotomist classes are for. Just make sure to maximize your training, understand the different needles and their applications, and you'll be on your way to being a good phlebotomist. A Phlebotomist is professional career just like any other. They are trained professionals who are skilled in collecting blood and gathering them.

Vulvodynia is defined as vulvar discomfort, most often described as burning pain, occurring in the absence of relevant visible findings or a specific, clinically identifiable neurologic disorder. The most common pain pattern in women with vulvodynia includes symptoms localized strictly to the vulvar vestibule: localized vulvodynia or vestibulodynia.

Symptoms can take the form of burning and any combination of stinging, irritation, itching, pain, and dyspareunia. Introital dyspareunia, the intensity of which may inhibit or prevent intercourse, is often the presenting symptom. The etiology of vestibulodynia is not established. The prevailing theory is that vestibulodynia is a neuropathic disorder involving abnormal pain perception;  dysfunction of the pelvic floor muscles may be a component. Multiple treatments have been used for vulvodynia, including vulvar care measures; topical, oral, and injectable medications; biofeedback; physical therapy; a low-oxalate diet and calcium citrate supplementation; and surgery. Treatment is directed toward alleviating symptoms and may provide partial or complete relief. Although some patients experience relief with a particular treatment regimen, others may not respond to it or experience unacceptable side effects. No single treatment is appropriate for every patient, and it may take a considerable amount of time to find a treatment or combination of treatments that will alleviate the pain. Vaginal dilators are used in a variety of clinical situations, including the treatment of vaginismus, avoidance of vaginal adhesion, and stenosis following radiation therapy. In this study, we report the evaluation of a particular set of vaginal dilators (Amielle Comfort) as a part of vestibulodynia therapy.

Care of the Urine Drainage Bag and Leg Bag

The Foley catheter is a tube that helps drain urine from the bladder. It is used by some patients who have had urological or gynecological surgery, or who have a condition that makes urination difficult.

Describe me
The urinary  catheter is placed into the bladder through the urethra, the opening through which urine passes. The catheter is held in place in the bladder by a small, water-filled balloon. In order to collect the urine that drains through the catheter, the catheter is connected to a bag. It is either a regular (large bag) drainage bag or a small leg bag.

If you have a urinary catheter, you will use the larger drainage bag at night while you are sleeping. You can use the leg bag during the day..

Attaching or removing a leg bag
The leg bag is attached to your leg and allows you to move around more easily. Because the bag is hidden under your clothes, it may also make you feel more comfortable about the catheter.


To attach or remove a leg bag, you will need the following materials:

Clean leg bag(s)
Leg straps or tape
Cotton balls and alcohol pads
White vinegar
Water and a towel
Regular (large) drainage bag
To attach or remove the leg bag:

Wash your hands with soap and water for 15 seconds.
Empty the large drainage bag. The different types of drainage bags open in different ways: a drain spout that you remove from its sleeve, a clamp that you open to the side, or an opening that you twist. Whichever method you use, be sure to not touch the tip when you let the urine flow out of the large drainage bag into the container or toilet.
Place a towel under the connection between the catheter and the bag.
Pinch off the soft rubber tube (the catheter tube) so that urine doesn't leak out.
Disconnect the urinary  catheter tube from the current large drainage bag with a twisting motion. Keep pinching the soft rubber tube (the catheter tube) so that urine does not leak out.
Be careful not to pull on the catheter. Place the old large drainage bag on the towel.
Prepare to place the leg bag in the catheter tube from which you just disconnected the large drainage bag. Remove the protective coating from the tip of the leg bag drainage tube. (Save this tip to use later when you change back). Clean the tip with an alcohol pad, wiping away from the opening to avoid getting the tube dirty. Insert the tip in the catheter tube.
Fasten the straps of the leg bag to your thigh. Secure the catheter itself to your leg with tape. Be sure to leave some slack in the catheter so that you don't put too much pressure on the bladder, urethra, and other parts of the body. Don't fasten the straps on the leg bag too tightly to your leg, as that may interfere with your circulation. If the leg strap gets dirty, wash it with soap and water.
Emptying the leg bag
Please note that because a leg bag is smaller than a regular drainage bag, it will have to be emptied more frequently.

Empty the leg bag when it is half-full, or at least twice a day.
Place a large plastic or metal container on the floor next to you. You may also empty the urine into the toilet. The nurse may give you a container to use at home.
Wash your hands with soap and water.
The different types of drainage bags open in different ways: a drain spout that you remove from its sleeve, a clamp that you open to the side, or an opening that you twist. Whichever method you use, be sure to not touch the tip when you let the urine flow out of the urine bag into the container or toilet.
When the bag is empty, close the clamp or twist on the cap on the leg bag.
Wash your hands with soap and water.
Write down how much urine was in your bag, if your caregivers have asked you to keep a record.
It is a good idea to occasionally change your leg bag from one leg to the other. The best time to do this is right after you shower.

Cleaning the bag
When you are ready to go to sleep, change out the leg bag and put on the drainage bag. Rinse out the leg bag with 1 part vinegar and 3 parts water. Soak the bag for 20 minutes. Rinse the bag out with warm water and hang it up to dry.
In the morning, take off the drainage bag, put on the leg bag, and clean out the drainage bag the same way.
Clean your leg bag every day and replace it whenever your doctor tells you to. This is usually once a month.

3 Watering Methods for Chameleon Care

Dehydration is one of the most common health issues when it comes to caring for your chameleon. You will know when your chameleon is dehydrated by checking if it has sunken eyes. Then check if its skin does not go back in place when you lightly pull it. If the skin doesn't go back into place, your chameleon is most definitely dehydrated.

The best move to solve this health problem would be to give your chameleon more water. Here are the three best watering methods to help care for your chameleon:

1. The Drip System: This method allows your chameleon to have water available to it for a long period of time. It involves a receptacle to release water. One way is to put ice cubes on the roof of your chameleon's enclosure and letting it melt to drip on your chameleon. Another way is to make a small hole at the bottom of a plastic cup or container. Put it at the top part of the chameleon's cage, then fill it with water. Put the cup or container where the water dripping would fall on the leaves and plants in the cage or enclosure. The chameleon likes to drink water dripping from the leaves.

2. Spraying or Misting: This is an effective method of watering your chameleon. It not only helps your quench your chameleon's thirst, it also helps water the plants and increase the humidity level inside your chameleon's cage enclosure. The most common method for this would be using a spray bottle. Remember to use a clean bottle, and hot water (not boiling). Spray the water at least 2 feet away from the chameleon for the water to have time to cool a little as you spray it around. You can also use a garden spray for this; just make sure it's clean.

3. Manual Watering: There are those who want to see to ti that their chameleons are really drinking water. The oral syringe (without the needle) is used to manually drip the water slowly into the chameleon's mouth. This method, though, requires lots of patience from the owner as you cannot rush a chameleon in his drinking. Another method is using a rodent bottle. A rodent bottle has a metal tube with a ball bearing in the tip. This is also used to manually drip the water into the chameleon's mouth. Make sure that the syringe and the bottle are clean and that you use fresh water.

You can always opt to have your chameleon shower for an hour with a plant if you're desperate for it to be back on its healthful self. Make sure there is a plant because the chameleon will drink dripping water from it. Then spray the cage before putting the chameleon back in for moisture and humidity in its home.

A Brief Discussion on Types of Needles and Syringes

Needles and Syringes are among the most used medical apparatus. In this article, we will be discussing about some of the most used types of these medical apparatus.

The most widely discussed classifications of syringes are non Luer Lok and Luer Lok syringes. This classification is made based on the kind of tip these units possess. The Luer-Lok syringes come equipped with tips that need needles that get twisted and locked into appropriate place. This design ensures that the needle doesn't slip out of the syringe accidentally. The other type i.e. the non Luer Lok syringes come with tips which need needles that get pressed onto them; you will not need to twist these needles to place them properly.

There's another way of classifying syringes; this time we are classifying it based on the purpose it's used for. The two most widely used types include insulin syringe and tuberculin syringe. The insulin syringes are significantly small in size and are capable of holding 0.3 to 1 ml of medication. They are usually calibrated in units instead of milliliters. The majority of the insulin syringes get calibrated up to hundred units. Another important characteristic of these syringes is that they are designed to allow seamless self-injection. They are mostly used for administering subcutaneous injections.

The other type i.e. tuberculin syringes are used to test patients for tuberculosis. The fluid in these syringes gets injected directly into the patient's skin. Although these syringes are small in size, unlike the insulin syringes, they get calibrated in milliliters. The most prominent feature of the tuberculin syringes is their thin barrel that comes equipped with a pre-attached needle. These pieces are capable of accommodating 1 ml of medication. Here, it must be mentioned that in spite having a petite structure, they cannot be used for giving insulin.

Now, let us discuss about needles and their types. The majority of the needles available on the market currently have stainless steel body. They have a hollow structure and boast a miniature hole right at the middle. Their bodies are segregated into three main parts, the hub, the shaft and the bevel. The hub is the part that fits onto the syringe's tip. The shaft of the needle is its long slender part. A needle's bevel, on the other hand, is its slanted tip.

Needles are usually classified based on their diameter and length. Their length ranges between 0.5 inch and 3 inches. Their diameter gets measured in gauge. A 19 gauge needle is known to possess bigger diameter than a 25 gauge piece. This means the greater would be the gauge of a needle and smaller would be its diameter.

Surgical Suture Needle - Types and Uses

Cuts, wounds and injuries bring idea of bleeding body parts. All these of wounds are now quickly taken care of by different medical devices. Safest way to handle cuts and wounds is by using sutures. Other method such staple is also very effective to hold the wound closed. Surgical suture needle is main medical equipment used in any wound care procedure. Surgical needles are made with various materials but mainly these are made with stainless steel allows.

Stainless steel which is used in manufacturing of surgical needle has excellent resistance to corrosion. Every good type of stainless steel contain at least 13% of chromium, which allows a thin, protective surface layer of chromium oxide to from when the steel is exposed to oxygen. Researchers use the concept of high nickel maraging stainless steels for developing highly quality stainless steel wires for use as surgical needles. Depending on the nature of injury, different types of needle selection is made by the doctors and surgeons for closure of wound. Ideal surgical suture needles should have characteristics such as:
"    It should be made of high quality stainless steel.
"    Smallest diameter which should remain stable in the grasp of the needle holder
"    It should be sharp enough to penetrate tissue with minimal resistance.
"    It should be capable of implanting suture material through tissue with trauma.
"    It should be sterile and corrosion-resistant to prevent introduction of microorganisms of foreign materials into the wound.

There are also four different types of surgical needles. First body type of needle is of straight type which is used suture easily accessible tissue that can be manipulated directly by hand. Straight type of needle is helpful in microsurgery for nerve and vessel surgeries. The second type of needle is half-curved ski type. This type of needle is only used by expert paramedical staff and surgeons because of its body shape which is quite difficult to handle. Third type of needle body type is curved needle. This type of body needle requires less space for maneuvering as compare to straight needle. Curved needle is also available in different sizes such as quarter-inch, three eighths-inch, half-inch, and five eighths-inch circle. Fro skin closures three eighths-inch circle is commonly used. Last in line is compound curved surgical needle. This type of needle is most complex type of needle in all types. The needle curvature was in fact developed for anterior segment ophthalmic surgery.

Medical Plastic Products Industry, An Urgent Need To Strengthen Technical Innovation

At present, about one million people worldwide have three people in uremic patients, they need to have regular kidney dialysis, so hollow plastic fiber kidney dialysis machine needs a huge number. However, the hollow plastic fiber kidney dialysis machine market fundamentals for the United States, Germany, Sweden and Japan and other developed countries monopolize. China hospital kidney dialysis machine 90% of imported products. At present, the domestic hollow plastic fiber kidney dialysis machine, not only in quality than similar products in developed countries, production is running out. Many domestic hospitals for fear of domestic hollow plastic fibers, but the quality of kidney dialysis machines can not easily be purchased off of. In addition, while the demand from the market point of view, development and production of domestically produced high-quality plastic hollow fiber kidney dialysis machine has good prospects, but unfortunately, our country has in the production of specialty plastic dialysis hollow fibers have not yet made significant technological breakthrough, most dependent on imports.

Urgent need for replacement of artificial heart-lung machine
At present, the foreign hospital for bypass surgery required an artificial heart-lung machine (oxygenator) has plastic membrane oxygenator, but my hospital is still using the backward Bubble oxygenator. Western medical researchers believe that the plastic membrane oxygenator in the future is bound to replace the traditional bubble-type oxygenator, as the former effect on plasma components smaller. It is predicted that due to a number of countries like China are still the same should be gradually to replace the bubble-type oxygenator, therefore, plastic membrane oxygenator will be the next 10 years, best-selling products on the international market.

In addition to these products, domestic and overseas markets for much-needed artificial heart valves, artificial blood vessels, artificial joints and other orthopedic implantable medical devices such as high-end production of plastic products, China is still in its infancy, both in product quality, quantity or variety of both unable to compete with similar products in developed countries.

In view of this, our medical plastic products to break the high-volume, low-return of the existing structure, the only way out is to increase investment to develop much-needed domestic and foreign markets high-end medical plastic products. Otherwise, as in Vietnam, Thailand and Malaysia and other Southeast Asian newly industrialized countries of the medical plastic products processing industry, the rapid rise in the future is bound to low-end of our disposable syringes and other medical plastic products pose a threat to the export.

Tao Meaning Or Definition
道 is the Chinese character for Tao. The Character translates as 'way', 'path', or 'route', but philosophically 道 denotes the fundamentally true nature of the world. While the Chinese character for Tao is itself 'the way', it's often more loosely interpreted as the character for 'doctrine' or 'principle'.

East Asian religions and ancient Chinese philosophy like Taoism, and Confucianism believe in Tao.

Tao is everything we know and don't know that exists. It's a concept about everything encompassed by Tao. The universe and everything we perceive is a subset of Tao.

Tao Surname
Tao is also an Asian surname. Tao & Tao Technology, a Washingon family business formed by the Tao's, manufactures medical instruments such as the Tao Aspirator.

Urine drainage bags

Urine drainage bags collect urine. Your bag will attach to a catheter (tube) that is inside your bladder. You may have a catheter and urine drainage bag because you have urinary incontinence (leakage), urinary retention (not being able to urinate), surgery that made a catheter necessary, or another health problem.

How Your Leg Bag Works
Urine will pass through the catheter from your bladder into the leg bag.

Your leg bag will be attached to you all day. You can move around freely with it.
You can hide your leg bag under skirts, dresses, or pants. They come in all different sizes and styles.
At night, you will need to use a bedside bag with a larger capacity.
Where to place your leg bag:

Attach your leg bag to your thigh with Velcro or elastic straps.
Make sure the bag is always lower than your bladder. This keeps urine from flowing back into your bladder.
Emptying Your Leg Bag
Always empty your bag in a clean bathroom. DO NOT let the bag or tube openings touch any of the bathroom surfaces (toilet, wall, floor, and others). Empty your bag into the toilet at least two or three times a day, or when it is a third to a half full.

Follow these steps for emptying your bag:

Wash your hands well.
Keep the bag below your hip or bladder as you empty it.
Hold the bag over the toilet, or the special container your doctor gave you.
Open the spout at the bottom of the bag, and empty it into the toilet or container.
DO NOT let the bag touch the rim of the toilet or container.
Clean the spout with rubbing alcohol and a cotton ball or gauze.
Close the spout tightly.
DO NOT place the bag on the floor. Attach it to your leg again.
Wash your hands again.
Changing Your Leg Bag
Change your bag once a month. Change it sooner if it smells bad or looks dirty. Follow these steps for changing your bag:

Wash your hands well.
Disconnect the valve at the end of the tube near the bag. Try not to pull too hard. DO NOT let the end of the tube or bag touch anything, including your hands.
Clean the end of the tube with rubbing alcohol and a cotton ball or gauze.
Clean the opening of the clean bag with rubbing alcohol and a cotton ball or gauze if it is not a new bag.
Attach the tube to the bag tightly.
Strap the bag to your leg.
Wash your hands again.
Cleaning Your Leg Bag
Clean your bedside bag each morning. Clean your leg bag each night before changing to the bedside bag.

Wash your hands well.
Disconnect the tube from the bag. Attach the tube to a clean bag.
Clean the used bag by filling it with a solution of 2 parts white vinegar and 3 parts water. Or, you can use 1 tablespoon of chlorine bleach mixed with about a half cup of water.
Close the bag with the cleaning liquid in it. Shake the bag a little.
Let the bag soak in this solution for 20 minutes.
Hang the bag to dry with the bottom spout hanging down.
When to Call the Doctor
A urinary tract infection is the most common problem for people with an indwelling urinary catheter.

How Ostomy Bags Work

An ostomy is a surgical diversion of the digestive or urinary system that bypasses normal elimination and provides for evacuation of waste products directly through an opening in the skin called a stoma. Because the waste products drain involuntarily, there must be some means of capturing them and storing them. This is accomplished by using small pouches called ostomy bags. These, along with several necessary ostomy supplies, make it possible to function with an ostomy.

Ostomy bags are of two types: colostomy bags and urostomy bags, the former for the digestive system and the latter for the urinary tract. In all cases, they attach to the stoma by a flange which has an adhesive that secures the bag to the skin. Some ostomy bags are one piece, with an integral flange; some are two pieces, where the flange stays attached to the stoma and the bag is detachable.

Colostomy bags are either closed-end pouch or open-end pouch types. Open-end pouches are used when the colostomy is high on the colon and watery, irregular feces are excreted. The bottom can be opened and the waste drained. A closed end pouch is designed to be filled and discarded. A uroscopy bag can be one-piece or two pieces as well, but it generally includes a drain for emptying the urine. Ancillary ostomy products include waterproof tape to seal the edges of the flange, and night drainage systems that attach to the drain of a urostomy bag and allow the patient to sleep undisturbed.

Advantages of Disposable Medical Products

Disposable medical products offer many advantages that are recognized by a range of different consumers, from hospital staff, to private physicians, patients, and even non-medical professionals such as tattoo artists and electrologists. Certain disposable medical supplies such as bandages, gloves, and gauze have been used in clinics, hospitals, and doctors' offices for decades. Recently, however, the disposable medical supply market has increased significantly. In the modern healthcare setting, everything from scalpels to sheets and thermometers are available as disposable medical products. Disposable medical supplies bring many benefits, including convenience and safety.

Hospitals

The hospital setting is often busy and crowded, which creates unique challenges for effective healthcare. With so many sick patients, there is a serious risk that infections may spread from one patient to another. Patients with compromised immune systems are especially vulnerable to acquiring new infections and suffering serious consequences as a result. Infections can spread if contaminated items such as face masks or spirometers are used for multiple patients. Disposable medical supplies are a proven solution for reducing hospital-acquired infections .Single-use disposables can greatly reduce the risk of cross-contamination. For instance, the World Health Organization recommends using disposable needles and syringes when possible to reduce the risk of hospital-acquired infections.

Hospital workers, including doctors, nurses, emergency technicians, and support staff are often overworked and in a rush to care for all their patients. With time at a premium, having equipment that is ready-to-go is essential to streamlining patient care. Whether it is a disposable syringe, speculum, or hospital gown, single use medical supplies are fast and easy to use. A large investment of time and effort is required to clean and disinfect reusable medical products. With disposable medical products, the needed item is always ready to use without the hassle of washing it after the last use.

Private Medical Practices

Many doctor's offices also struggle with heavy patient volume, with a limited amount of time to see each patient. Disposable medical supplies that allow physicians to care for patients more efficiently without hurting the quality of care, such as disposable respirators and surgical masks, are a welcome change. Single-use disposables are equally as effective as reusable medical products and they save the clinician valuable time and effort. In addition, disposable medical supplies can save doctor's offices the expense of buying an autoclave to sterilize their equipment.

Patients

Patients appreciate disposable medical products for a number of reasons. First of all, they can trust the safety and sterility of a single-use disposable medical product. Instead of worrying about whether their doctors took the time to properly disinfect their equipment since the last patient, it is obvious that the equipment is sterile and unused.

In addition, patients in the home health care market who need items such as syringes, oxygen masks, or other products greatly benefit from the ease and convenience of disposable medical supplies.

Whatever a practitioner or patient's background, disposable medical products clearly offer many advantages for each individual. Whether the driving motivation is safety, convenience, or availability, more and more people are turning to medical supplies to meet their diverse needs.

Medical syringes

The threads of the Luer lock tip of this 12mL disposable syringe keep it securely connected to a tube or other apparatus.

An old glass syringe.
Sectors in the syringe and needle market include disposable and safety syringes, injection pens, needleless injectors, insulin pumps, and specialty needles. Hypodermic syringes are used with hypodermic needles to inject liquid or gases into body tissues, or to remove from the body. Injecting of air into a blood vessel is hazardous, as it may cause an air embolism; preventing embolisms by removing air from the syringe is one of the reasons for the familiar image of holding a hypodermic syringe pointing upward, tapping it, and expelling a small amount of liquid before an injection into the bloodstream.

The barrel of a syringe is made of plastic or glass, usually has graduated marks indicating the volume of fluid in the syringe, and is nearly always transparent. Glass syringes may be sterilized in an autoclave. However, most modern medical syringes are plastic with a rubber piston, because this type seals much better between the piston and the barrel and because they are cheap enough to dispose of after being used only once, reducing the risk of spreading blood-borne diseases. Reuse of needles and syringes has caused spread of diseases, especially HIV and hepatitis, among intravenous drug users. Syringes are, however, commonly reused by diabetics, and this is safe if the syringe is only used by one person. In medical settings, single-use needles and syringes effectively reduce the risk of cross-contamination.

Medical syringes are sometimes used without a needle for orally administering liquid medicines to young children or animals, or milk to small young animals, because the dose can be measured accurately and it is easier to squirt the medicine into the subject's mouth instead of coaxing the subject to drink out of a measuring spoon.

Tip designs
Syringes come with a number of designs for the area in which the blade locks to the syringe body. Perhaps the most well known of these is the Luer lock, which simply twists the two together.

Bodies featuring a small, plain connection are known as slip tips and are useful for when the syringe is being connected to something not featuring a screw lock mechanism.

Similar to this is the catheter tip, which is essentially a slip tip but longer and tapered, making it good for pushing into things where there the plastic taper can form a tight seal. These can also be used for rinsing out wounds or large abscesses in veterinary use.

There is also an eccentric tip, where the nozzle at the end of the syringe is not in the centre of the syringe but at the side. This causes the blade attached to the syringe to lie almost in line with the walls of the syringe itself and they are used when the blade needs to get very close to parallel with the skin (when injecting into a surface vein or artery for example).
