Description

Needle cap capable of preventing needle from being injured by needle

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a needle cap capable of preventing needle stick injury.

Background

The advent of syringes is an epoch-making revolution in the field of medical devices. This process of drawing, injecting gas or liquid with a needle is called injection. The injector consists of a syringe with a small hole at the front end and a matched piston core rod, and is used for injecting a small amount of liquid or extracting the liquid or the liquid from the inaccessible area by other methods, wherein the liquid or gas is sucked from the small hole at the front end of the syringe when the core rod is pulled out, and the liquid or gas is extruded when the core rod is pushed in.

The puncture refers to the wound caused by the sharp penetration of sharp objects (such as knife tips, bamboo sticks and the like) into the skin and subcutaneous tissues. The puncture wound appears as a small hole in the skin and there is little blood flow, but the wound is usually deep and sometimes internal organs are injured. Puncture wounds can have serious consequences, since the wound path is likely to be blocked by blood clots or, due to the presence of contaminant residues in the wound, infections, especially anaerobic infections, are likely to occur.

The injector is commonly used for intravenous injection of small-dose medicines such as vaccines, antibiotics and the like, and the needle needs to be properly treated specially for the injector after injection of special people, so that secondary infection caused by accidental stabbing is prevented.

The needle cap of the prior injector is easy to separate, drop and lose; the diameter of the cap hole is small, and the difficulty is increased when the cap is sleeved back by a single hand; the needle cap is improved by increasing the action repeatability, inconvenient operation and increased danger, and the needle cap for preventing the needle from being injured by the needle is provided.
