Butterfly catheter - for all occasions

What are peripheral catheters used for?

A peripheral catheter is a medical device designed and used for long-term (up to three days) insertion. medicines, fluids into the venous vessels or removal of fluids from the circulatory system.

The catheter is inserted using a special hollow needle. This product is usually inserted into the arms, neck or head. In this case, various infusion systems are connected to the second end of the catheter.

Interestingly, such products are the best option when there is a need intravenous administration drugs for a long time.

What is a butterfly needle?

A butterfly catheter is a type of intravenous catheter. This is a sterile, single-use injection needle with locking wings that is great for short-term drug administration or blood collection.

The main purpose of the “butterfly” for which it is suitable the best way– introduction of medications and drugs into peripheral small veins during infusion therapy. Also, a butterfly catheter, which you can buy on our website in the appropriate section, provides the opportunity to collect blood from so-called “problem patients.” At the same time, it is the latter reason that determines the high demand and relevance in the departments of intensive care, pediatrics and veterinary medicine.

As practice shows, peripheral veins located on the forearms or in the cubital fossae are most often used to carry out procedures for intravenous administration of drugs and solutions, as well as drawing blood using a butterfly needle.

Features of the butterfly needle

This catheter is characterized by a number of advantages and disadvantages, which in many cases make this product indispensable during medical procedures.

The first advantage is that the main element, the puncture needle, is made of the finest medical steel highest quality, which makes it possible to guarantee its maximum level of strength along with minimum thickness walls

The needle is only 1.9 cm long, which, together with the triple sharpening system, ensures its insertion under the skin into the veins with virtually no pain or injury.

The insertion and collection procedures are carried out through thin transparent connecting tubes made of polyvinyl chloride, which are highly resistant to various kinds of kinks.

What’s interesting is that the wings, from which the catheter received its original name, allow the catheter to be firmly and reliably fixed and avoid its spontaneous removal, which is very necessary and in demand in many cases.

The butterfly needle is a simple, highly effective and reliable peripheral catheter, which can be easily purchased in our online store at an affordable price.

The “Butterfly Needle” device is intended for insertion into peripheral small veins during intravenous infusion. Butterfly needles are especially relevant in pediatrics, intensive care units and veterinary medicine.

• short atraumatic needles with special sharpening ensure easy, safe penetration under the skin
• Flexible “wings” provide easy and effective fixation. The wings have color coding depending on the size of the injection needle. Butterfly needles are sized according to needle sizes.
• the infusion occurs through thin flexible connecting tubes, thanks to which the needle does not move inside the vein when manipulating the tube and, therefore, the risk of mechanical damage to the vessel wall is minimized.
• Protective plug cap provides additional convenience during repeated infusions

What you need to know about catheters and butterflies?

About 10 years ago from medical instruments For administering medications, only syringes were known, and even then they were reusable. Today, scientific and technological progress has made it possible to evaluate the advantages of sterile disposable syringes, blood transfusion systems, droppers and catheters.

What is a catheter and why is it needed?

Catheters are intended for long-term infusion of medications. They are intravenous, intra-arterial, as well as for lymphatic vessels and hemodialysis. Each product is individually packaged and looks like a sophisticated, modernized needle. The top is made of transparent medical plastic, through which you can clearly see the catheter and needle itself.

How are catheters different from butterfly needles?

A “butterfly” is a needle that has additional adhesive wings that allow it to be fixed to the skin. But besides this there are a few more fundamental differences:

• When using a catheter, the catheter itself remains in the vessel, and when using butterflies, the needle remains.
• The hand in which the catheter is located can be safely moved and not worry about damaging the vein - such a device can remain in the vein for up to three days. While the slightest displacement of the skin or arm in which the butterfly is installed can injure the veins, that is why the time of use should not exceed 1 hour.
• “Butterflies” are used for short-term infusions and manipulations, and catheters for long-term ones. Scope of application The scope of catheters depends on its type:
• Intravenous catheters for peripheral veins are widely used in all surgical interventions and during childbirth.
• Products that are installed in central veins are more often used in cardiac surgery, intensive care, and oncology.
• Catheters for moving from peripheral to central veins are needed in neonatology, oncology and intensive care.
• Intra-arterial ones must clearly withstand blood pressure. Used in toxicology, vascular and cardiac surgery.

BUTTERFLY NEEDLE WITH CATHETER

General information. Children early age medicinal substances can be injected into the superficial veins of the head. During the procedure, the child is restrained. His head is held by a nurse assistant, his arms to his body and his legs are fixed with a diaper (sheet). If there is hair at the site of the intended puncture, the hair is shaved off.

Indications: impossibility of intravenous administration medicines into other peripheral and central veins.

Contraindications: damage to the scalp.

Injection sites: saphenous veins of the temporal and frontal areas of the skull.

Workplace equipment: 1) butterfly needle with a disposable catheter; 2) a bottle with a filled system for single-use intravenous drips, a stand; 3) ampoule (bottle) with 0.9% sodium chloride solution; 4) single-use syringe with a volume of 5 ml, injection needles; 5) sterile material (cotton balls, gauze triangles, napkins, diapers) in packages or boxes; 6) tray for sterile material; 7) tray for used material; 8) pins in packaging; 9) sterile tweezers; 10) tweezers in a disinfectant solution; 11) file, scissors; 12) a dispenser container with an antiseptic for treating the skin of patients and the hands of staff; 13) a container with a disinfectant solution for processing ampoules and other medicinal injection forms; 14) a patch (regular or Tegoderm type) or other fixing bandage; 15) medical gloves (single use); mask, goggles (plastic screen), waterproof, disinfected apron; 16) tweezers for working with used instruments; 17) containers with disinfectant for treating surfaces, washing used needles, syringes (systems), soaking used syringes (systems), needles, disinfecting cotton balls and gauze wipes, used rags; 18) clean rags; 19) tool table.

Preparatory stage of the manipulation: 1. Inform the patient (close relatives) about the need to perform and the essence of the procedure.

2. Obtain the consent of the patient (close relatives) to perform the procedure.

3. Wash your hands under running water, lathering twice. Dry your hands with a disposable napkin (individual towel). Treat your hands with an antiseptic. Wear an apron, gloves, and mask.

4. Treat the surface of the manipulation table, tray, apron, and system stand with a disinfectant solution. Wash your gloved hands under running water and soap, dry, and treat with an antiseptic.

5. Place the necessary equipment on the tool table.

6. Cover the sterile tray.

7. Print out the packages with the butterfly catheter and syringes and place them on a tray. Another option for working with sterile material when it is in packages.

8. Treat the ampoule (bottle) with sodium chloride solution 0.9%.

9. Draw 2 ml into the syringe connect to the catheter, fill it and place it on the tray.

10. Fix the child (performed by a nurse assistant). Place a sterile diaper next to the baby's head.

11. Wear safety glasses (plastic shield).

The main stage of performing the manipulation.12. Select a vessel for puncture and treat the injection site with two balls of antiseptic (one wide, the other narrow) in the direction from the parietal to the frontal region. For better blood supply to the vein, it is convenient to use a special elastic band placed around the head below the punctured area (above the eyebrows). Local digital compression of the vein is ineffective due to the abundance of venous anastomoses of the cranial vault. A baby's crying also causes the veins in the head to swell.

13. Treat gloved hands with an antiseptic.

14. Stretch the skin in the area of ​​the intended puncture to fix the vein.

15. Puncture the vein with a butterfly needle and catheter in three stages . To do this, direct the needle along the blood flow under acute angle to the surface of the skin and puncture it. Then advance the needle approximately 0.5 cm, pierce the vein and guide it along its course. If the needle is not in the vein, return it without removing it from under the skin and re-puncture the vein.

Inserting a needle into a vessel immediately after puncturing the skin may puncture both walls of the vessel.

16. Pull the plunger of the syringe connected to the catheter. The appearance of blood indicates the correct position of the needle. If an elastic band was used to increase blood flow to the vein, remove it.

17. Inject 1 - 1.5 ml sodium chloride solution 0.9%, to avoid thrombosis of the needle with a blood clot and eliminate the possibility of extravasal administration of the drug.

18. Secure the needle with three strips of adhesive tape: 1st - across the needle to the skin. 2nd - under the “wings” of the “butterfly” needle with a cross above them and fixation to the skin, 3rd - across the wings of the “butterfly” needle to the skin.

19. Roll the catheter into a ring and secure it with an adhesive tape on the scalp to prevent it from dislodging.

20. If necessary, if the angle of the needle relative to the curve of the skull is large, place a gauze (cotton) ball under the cannula of the needle.

21. Pull the plunger of the syringe connected to the catheter to re-check needle position in the vein.

22. Disconnect the syringe, connect the dropper to the solution stream.

23. Use the clamp to adjust the rate of administration of the medicinal substance.

24. Cover with sterile gauze pad the junction of the catheter cannulas and the dropper.
