Multiple practice methods: Intradermal injection model practice method: air or liquid can be injected during practice. Correct penetration into the skin will cause local formation of skin hills, and incorrect penetration into the skin will not produce skin hills. Repeat the exercise at each point. The practice method of intravenous injection model (without liquid): Inject air. If the sac is swollen, it will prove to be inserted into the blood vessel correctly. If there is no response, it will not be pierced correctly. Intravenous injection model practice method (injecting liquid to produce blood return): You can inject about 5ML of tap water to fill the reservoir. The amount of water should not be too much, the pressure will be too high before the puncture is correct, the blood return can be seen, the novice is not sure whether the blood vessel is inserted correctly , You can first pierce the empty cylinder to see the sac swells and then fix the needle, pull out the empty cylinder, and fill the cylinder with water and inject the liquid. Nurse blood collection exercise (inject liquid for blood collection exercise): inject about 5ML of tap water in advance to fill the reservoir, and then puncture to see the blood return, insert the container for practice, the container can repeat the exercise, remove the lid to pour the liquid, and then cover it for use You can practice again after the needle draws out the air to form a negative pressure. Specification: Name: Intradermal injection training model Purpose: Inject into the skin below the epidermis, generally above the dermis, but not into the subcutaneous tissue Features: artificial skin, 15 skin pilot positions, correct injection can produce skin hills Material: outer layer of silicone skin, inner layer of foam board, sponge Size: 16cm*11.5cm*2cm Package Contents: 1 ×Intravenous Injection Model 1 ×Intradermal Injection ModelUse our injection kit for continuous practice to ensure that you have the confidence to deal with various types of wounds at the critical moment.

Package Contents:1 ×Intravenous Injection Model, 1 ×Intradermal Injection Model.Can be used for Venipuncture IV Injection, Injection Training, Infusion training, Blood transfusion and Intradermal injection Training. In addition to general injection practicing, this injection pad it can be used by training providers for teaching demonstrations, exams and study practice. Realistic Silicone Skin Quality, Inner Foam Board, Sponge Material. The design of the liquid storage bladder makes it easier to generate blood return or blood collection practice. The high-quality silicone injection pad closely simulates the human body tissues and simulates human flesh extremely realistically. Air or liquid can be injected during practice. Correct penetration into the skin will cause local formation of skin hills, and incorrect penetration into the skin will not produce skin hills. Simulation students are aimed at Operate in real scenes.
