Description

Technical Field

[0001] The utility model relates to the technical field of injection, in particular to an injection needle placement mechanism to prevent punctures. Background Art

[0002] Injection refers to the injection of liquid or gas into the human body with the help of medical devices such as syringes, in order to diagnose, treat and prevent diseases. It is different from taking medicine. After injection, the medicine can quickly reach the blood and take effect.

[0003] Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolytes, and drugs into the body through the veins by using the principles of atmospheric pressure and liquid static pressure. Intravenous infusion needles are used to connect syringes, infusion sets, and blood transfusion sets for intravenous infusion of liquid medicine and blood transfusion. However, after the infusion, the needle has no fixed placement position, so the needle can only be placed at will. The residual liquid in the infusion will cause environmental pollution, and when the needle loosens and falls, it is easy to cause puncture injuries to medical staff. Some viruses on the needle may even enter the body of the medical staff, causing irreversible damage. Therefore, an anti-puncture needle placement mechanism for injection is proposed to solve the above problems. Utility Model Content
