Needles, butterfly catheter for infusion into small veins. What you need to know about catheters and butterflies? Butterfly for dropper

A clinical blood test is one of the list of standard manipulations for examining patients for the purpose of prevention or treatment. It allows you to estimate the amount of hemoglobin, red blood cells, leukocytes, platelets, and identify the color indicator. Blood is collected in only two ways - from the ring finger or from a vein. A needle or butterfly catheter is used to collect venous blood. What do you need to know about medical instruments, what are their types and how to use a butterfly needle correctly?

What is a luer adapter?

The luer adapter is one of the components of the butterfly needle. Visually, it resembles a container for collecting, transporting and storing biological materials. One part of the device is a luer connector. With its help, the adapter is connected to the catheter holder. On the modern market you can find two variations of the device for collecting blood - with a luer adapter or a holder holder. Luer allows you to perform several manipulations at once - take blood for analysis, perform an intravenous injection, attach a needle to the system for infusion of solutions.

The second part of the device is a needle for piercing a vacuum tube. It is closed with a dense rubber cap, which prevents blood from splashing when removing or transporting the sample. All luer adapters are supplied in individual cases with an information label and perforations for visual inspection.

Butterfly catheter sizes for children. Butterfly needles: types, device, instructions for use

A butterfly needle is a simple type of intravenous catheter. This is a sterile, single use product. The product is designed for short-term administration of medications and blood collection.

Butterfly needles are sized for thin veins. They are suitable for taking samples from young children and are used in intensive care and veterinary medicine. Using devices, solutions and medications are administered intravenously, and biomaterial is collected from peripheral veins.

Design Features

• Due to the presence of a long catheter, the product has many advantages and is indispensable when carrying out a number of procedures on children.
• Made from thin medical steel, it is durable with minimal thickness.
• Butterfly needles vary in color and size, and international color coding is used.
• Triple sharpening for virtually painless insertion into the skin. Treating metal with silicone minimizes skin injury.
• The needle is called “butterfly”, thanks to the wing-shaped fixation device for strong and reliable fastening of the catheter. The design feature prevents spontaneous extraction.
• The drug is administered and blood is taken through transparent plastic tubes that can withstand kinks.

The butterfly needle complies with GOST, has a transparent tube made of medical polyvinyl chloride with a length of 18 to 30 cm, which allows operations to be carried out far from the venipuncture area - the risk of needle dislocation and damage to the vein is reduced. On one side there is a Luer or Luer-Lock connection with a cap. On the other, a catheter is placed for insertion into a vein.

The size range of products ensured the widespread use of butterfly needles. Products are selected depending on the characteristics of the vein, the density and viscosity of the injected drug. Color coding, in accordance with the ISO standard, is applied to the wings. It’s easy to determine the size by color and choose the right device.

The indication for use is the impossibility of administering drugs into central and peripheral veins. The device is used for short-term puncture – up to 6 hours – and intravenous infusions. See the instructions for how to use a butterfly needle.

How to insert a butterfly needle?

It is necessary to prepare the workplace. Place a device with a catheter, a bottle for drip infusions on the table, and install a tripod. To carry out the procedure, you will need sterile material, a container with a disinfectant composition, a plaster, gloves, and a table for instruments.

The butterfly needle is placed according to the instructions.

• Wash your hands, treat your skin with an antiseptic, put on gloves and a mask.
• Fill the infusion system, invert the bottle and secure it on the rack.
• Open the air valve and make sure there is no air.
• Perform hand hygiene again, put on gloves and a mask.
• Open the catheter package.
• Place a cushion under the patient's limb, apply a tourniquet over thin clothing or a napkin.
• Check the pulse below the tourniquet site.
• Massage the catheter insertion site with the edge of your palm from the periphery to the center. When inserted into the cubital vein, the patient is asked to make a fist.
• Select the injection site.
• Soak a cotton ball with an antiseptic and treat the area.
• Connect the product to the infusion system and wait until a drop of solution appears.
• Place the needle cut side up, bend the wings and remove the cap.
• Pull the skin just below the puncture site and secure the vein.
• Perform a puncture at an angle of 10-15 degrees, wait for blood to appear.
• Using your left hand, loosen and remove the tourniquet. Open the clamp on the system. If there is no infiltration, the device is in the vein.
• While holding the butterfly to prevent it from moving or being removed, secure the device with adhesive tape.
• Adjust the speed of solution administration.
• Observe the patient for 30 minutes.

Vacuum blood sampling: manipulation

• Ask the patient to make room for the upcoming venipuncture (most often the elbow, possibly the forearm, the back of the hand).
• Place an oilcloth pillow under the venipuncture site.
• Apply a tourniquet 7-10 cm above the venipuncture site on top of clothing or a diaper. The tourniquet is applied so that the pulsation of the nearby artery is maintained. The tourniquet application time is no more than 1 minute.
• Ask the patient to clench his fist (do not clench or unclench, but only clench and hold in that position!)
• Inspect and palpate the vein for venipuncture.
• Treat the venipuncture site with antiseptic wipes twice - first a large area, then the venipuncture site. Use 2 or more antiseptic wipes. The skin is processed from the center to the periphery in a circular motion.
• Hold the vacuum system in one hand and remove the protective cap from the needle with the other hand.
• With your free hand, stretch the skin below the venipuncture site at a distance of 4-5 cm to secure the vein.

• Puncture the vein at an angle of 10-15º, insert the needle along the vein no more than 1/2 of the length.
• Take the test tube and insert it into the holder until it stops.
• Once the blood begins to flow into the tube, remove or loosen the tourniquet.
• Ask the patient to unclench his fist.
• Draw the required amount of blood into a test tube.
• Remove the tube from the holder when blood stops flowing into it.
• Carefully invert the tube several times to mix the blood with the filler. Do not shake the test tube!
• Place the test tube in a rack.
• If necessary, connect the next test tube to the system and repeat all steps.

Butterfly catheter for how many days. Venous catheter: how often should it be changed. And is it necessary?

The installation of a venous catheter is widely used in nursing practice for intravenous fluid administration, but despite the obvious advantages in the work, the use of a peripheral catheter has its disadvantages, including dangerous complications.

No catheter - no problem

One of the predisposing factors for the occurrence of complications is the persistence of the venous catheter; this factor has become so relevant that inpatient departments are trying to either, as far as possible, replace catheters during the short period of its presence in the vein (up to 3-5 days), or remove it altogether, since The constant flow of patients and extensive nursing responsibilities do not allow for constant catheter care. Lack of care (washing, changing dressings, treating the venipuncture site) leads to the formation of phlebitis, blood clots and other complications, so the simplest and most optimal solution for employees is to remove the catheter.

But if you take into account all the care measures, how long is the catheter in the vein considered safe?

According to the methodological recommendations of RAMS (2011), it is allowed to leave a catheter in a vein for more than 72 hours only in case of difficult venous access and an urgent need for prolonged infusion therapy, provided that the phlebitis score does not exceed 1 point.

The international organization Cochrane, in a 2020 review of “clinically indicated peripheral venous catheter replacement versus routine replacement,” found no evidence of catheter replacement in the first 72 to 96 hours. This data has been included in National Health Service England guidelines. Therefore, in the National Health Service, venous catheters are changed only in case of clinical manifestations.

What recommendations should you follow?

According to the above facts, the presence of a venous catheter at the international level is not limited in time, but depends on the clinical manifestations and condition of the patient.

Nevertheless, it is worth taking into account the work on local SOPs developed for a specific organization, and actions in accordance with GOSTs, for example GOST R 52623.3-2015 (Table 9 - TPMUMSU “Care of a vascular catheter”) reports that if, while caring for a catheter, a nurse finds inflammation, it is necessary to arrange a call to the doctor.

You can also consult your doctor for permanent catheter removal or replacement.

Features of needle butterflies

Size range of butterfly needles: 18G, 19G, 20G, 21G, 22G, 23G, 25G, 27G (the choice is determined by the diameter of the vein and the viscosity of the injection solution).

Flexible polypropylene wings are needed for easy and effective fixation on the surface of the skin. They are painted in accordance with the ISO standard and allow medical personnel to quickly find the right size. The wings are marked with needle size.

A flexible, thin transparent tube made of special medical polyvinyl chloride, about 300mm (30cm) long. This length allows manipulation to be carried out far from the site of vein puncture, which reduces the risk of needle displacement in the vein (the needle is firmly fixed) and accidental mechanical damage to the vessel wall.

The needle (catheter) has a special sharpening, which ensures easy and painless insertion of the needle.

Butterfly needles should only be used by trained medical personnel and only in accordance with the instructions.

Often, butterfly needles are packaged as a “blood collection kit” - complete with a luer adapter or complete with a luer adapter and holder.
