Once in the stomach, drugs cause irritation of its walls. To avoid this, doctors recommend injecting medications. They are performed with a variety of syringes. Syringes are also used for the introduction of nutrients, washes, but special ones, for example, a single-use syringe Janet (150 ml).
Syringe design
By design, syringes are divided into two- and three-component. The first type is a syringe consisting of a cylinder and a piston. The volume of the tool, made in a two-component version, can be from two to twenty milliliters. Disposable syringe Janet (150 ml) also refers to two-component.
The three-component consists of a plunger, a piston and a cylinder (a plunger is a seal located at the end of the piston and ensures smooth movement of the piston along the cylinder).
Syringe Features
A syringe of a certain volume is used for each type of procedure. Small instruments up to 1 ml in volume are intended for vaccinations, intradermal and subcutaneous injections.
Syringes from 2 to 22 ml are used for subcutaneous, intramuscular and intravenous injections.
Syringes with a volume of 30 and more milliliters, including a 150 ml disposable syringe, are used for aspiration, sanitation, washing various cavities, and introducing nutrient solutions.
Appointment
Syringe have a different purpose.
Insulin They are used for injection of insulin. This species has a small volume (up to 1 ml) and a thin short needle. On the body, the markings indicate ED (units of insulin), not milliliters.
- Disposable syringe Janet 150 ml. This is the largest option, which is used for the introduction of various solutions through probes, for washing cavities, sanations.
- A syringe tube is a disposable tube that contains a dose of the drug inside. It is flexible, airtight and sterile, intended for quick assistance.
- A syringe pen helps inject insulin. This variety is an injection syringe with a thin needle and a convenient button.
- Dart - this variety is used in veterinary medicine with the introduction of drugs or temporary euthanasia of animals. Such syringes are loaded into special guns instead of cartridges.
- Luer syringe - this view is a small, 2-milliliter, and large syringe up to 100 g. The body is made of glass, inside a long piston. I use them for punctures and for intravenous injections.
- Pistol. The syringe is designed specifically for those who are afraid of injections. A syringe with a volume of up to 5 ml is charged into the gun, then the paramedic pulls the trigger and the medicine is injected. When using this device, injections are painless, and drugs are administered quickly.
- Syringe for infusion. This is a large syringe used to infuse drugs into the cavity. Models are similar to the Janet syringe, but have special tips and an elongated head.
- Karpulny syringe. It is used in dentistry during anesthesia. These models are both disposable and reusable.
There are other types of syringes that have a special purpose. These include: syringe flask, "Record".
Volume
All syringes are divided by volume. Depending on this indicator, instruments are divided into:
- Small volume syringes.
- Syringes of medium volume.
- High volume syringes.
The size of the syringes affects the accuracy of drug administration, and also determines the branch of medicine in which the tool is used.
Small volume syringes include instruments ranging in volume from 0.3 to 1 ml. They are used in endocrinology with the introduction of insulin, for vaccination, during intradermal tests. Small syringes are also used in phthisiology and neonatology.
Syringes of medium volume have a capacity of 2 to 22 two “cubes”. This species is considered universal and is used in all branches of medicine.
Medium volume syringes are used for intramuscular, intravenous, subcutaneous, intradermal and other injections.
Large volume syringes are used for aspirating various liquids, washing, introducing nutrients. Such tools have a volume of 30 g.
When choosing a tool, consider its quality. Cheap models have a lot of disadvantages, one of which is a tight piston. Working with such a tool is difficult. Be sure to consider the volume and purpose of the syringe. For intramuscular injections, 5 ml universal syringes are most often used. Tens and twenty are used for intravenous injection.
