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.

Color code	Needle size	Needle diameter	Catheter length	code of product
Needle 21 G*3.4″	0.8 mm	190 mm	594121190
Needle 25 G*3.4″	0.4 mm	300 mm	594125300

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.

Compound

The butterfly needle for the dropper is made from medical products that prevent the occurrence of allergic reactions and irritations when using the catheter.

Components of a medical cannula:

Material of manufacture	Part of a butterfly needle	What influence does the properties of the material have?
Medical grade polyvinyl chloride	A catheter 300 mm long is made directly from polyvinyl chloride. There is a connection on one side of the long catheter and a needle on the other.	Most medical devices are made from polyvinyl chloride. PVC meets all toxicological standards. The popular polymer is famous for its constant chemical composition. Over a long period of use, polyvinyl chloride does not crack or break, maintaining its physical properties. PVC is easy to paint and is highly flexible, favoring its use in pharmaceutical companies. The polymer is resistant to water and chemical compounds.
Surgical steel	The needle is attached to a long catheter. The sharpening on the needle ensures easy entry and penetration into the vein. There is also a protective cap on the needle.	Medical steel is one of the most popular materials in medicine. Among the properties that medical steel has, the most popular in medicine are resistance to chemical compounds, as a result of which the material does not corrode. Also, medical steel does not rust or lose shape when exposed to high temperatures. During use, stainless medical steel produces almost no scratches. Irregularities and damage can become a place for bacteria to accumulate. Products made from medical stainless steel are characterized by durability and reliability of use. There are also several types of medical steel depending on the alloys in the composition. The most popular is chromium ferritic steel.
Lightly dyed polyethylene, color coded	Flexible catheter wings are made from lightly colored material. Tint coding depends on the size of the needle and its area of application.	Color-coded low-dye polyethylene is another type of polymer that is widely used in medicine. Polyethylene is distinguished by its flexibility and strength, therefore it is used in the manufacture of catheter “wings”. The “wings” also indicate the type of butterfly needle and the corresponding color of the catheter, which characterizes the area of application of this product.

Each component of the butterfly needle has undergone extensive testing and is therefore safe for use with patients.

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 Cochrane organization's 2015 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.

Approximate instructions for using a butterfly needle to draw blood into a test tube

1. Select the required test tube and butterfly needle

2. Remove the butterfly needle from its individual packaging.

3. Select the site for puncture of the vessel, apply a tourniquet, and disinfect the site of vein puncture.

Firmly squeeze the “wings” of the butterfly needle and remove the protective cap from the needle.

4. Lower the patient’s arm a little down and insert the needle into the vein.

5. As soon as the blood is collected in the last tube, carefully remove the butterfly needle from the vein, while simultaneously pressing a sterile swab to the puncture site until the bleeding stops.

6. Dispose of the butterfly needle in a recycling container.

In what form is it produced?

There are several types of attachment of the tip to the direct catheter. The butterfly needle is characterized by Luer and Luer-lock fastenings.

Luer mount

The Luer mount is most often used for drawing blood from patients with seizures and other disorders. High-quality fastening and “wings” ensure reliable fixation of the needle in the patient’s vein, which avoids injury to blood vessels.

Luer-Slip is one of the simplest and cheapest options for butterfly needles : the needle is attached to the protruding part of the syringe barrel. There is also a classification according to the needle attachment: on the side of the cylinder and in the center of the cylinder. The cost of a butterfly needle with a flexible catheter is about 9 rubles.

Luer Lock mount

This type of mount is used for infusion of medications. The main distinctive feature of the fastening is the ability to change needles, since a screw connector is installed on the cylinder.

The needle must be screwed into the syringe barrel mount. With this type of fastening, the needle position is always central.

The fastening is characterized by non-invasiveness and the possibility of painless penetration under the skin. The butterfly catheter has locking “wings” that secure the product. Additionally, you can secure the needle and catheter with an antibacterial tape. Most catheters of this type have an indicator transparent chamber that allows you to view the needle entering the vein.

The cost of catheters depends on the manufacturer, as well as the size of the needle. For the simplest catheter, the average price is about 6-7 rubles per piece.

Regardless of the type of needle attachment, there is a large size table for butterfly catheters. The dimensions of the needle allow you to select the optimal type of product for a given vein diameter (needles are intended only for thin venous vessels) and the drug injected.

The length of the tube should be at least 30 cm, which will ensure normal fixation of the needle in the vein both in a quiet position and when moving the device.
