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.
