Description

Novel puncture-preventing easy-to-fix intravenous infusion needle

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to novel puncture-proof easily fixable venous transfusion needle.

Background

The disposable intravenous infusion needle used in clinic mainly comprises a protective cap, a needle body, a needle seat, needle wings and a connecting pipe, and during the use process, the following problems can occur, firstly, the needle wings are fixed, when a nurse carries out intravenous infusion operation, the needle wings are fixed by one hand after the nurse successfully punctures the needle wings, the adhesive tape is torn by the other hand, and the needle head is easy to shift to puncture blood vessels at the moment that the hand leaves the needle wing sticking infusion paste; secondly, the steel needle moves, and in the process of infusion, because the patient moves or carelessly pulls the infusion tube, the steel needle can swing in the blood vessel, the needle point can puncture the blood vessel, and the pain of the patient caused by multiple punctures is increased; the needle pulling problem is solved again: when the needle is pulled out, a nurse needs to pull out the needle quickly along the running direction of the blood vessel, but in the actual operation, the needle point is easy to turn and shift in the blood vessel, even the blood vessel wall is punctured; finally, the problem of needle stick injuries is one of the most common clinical hazards, and many studies indicate that needle stick injuries are the main mode of occupational exposure for medical personnel. After the transfusion needle is pulled out, the needle head stained with the blood of a patient is exposed outside, so that the puncture wound is easily caused, and the accidental injury and infection of medical care personnel and patients are more easily caused particularly in the process of arranging objects and treating the needle head by nurses and when a plurality of patients are busy in treatment; and after the needle head is pulled out, the residual liquid medicine of the infusion tube and/or the blood in the blood vessel of the patient flow back to the infusion needle tube, and blood drips from the needle head to pollute the ground and the environment, thereby increasing the chance of nosocomial infection.

Therefore, it is a problem to be studied to provide a new anti-puncture and fixed intravenous infusion needle that can fix the needle wings and prevent the needle from puncturing the blood vessel of the patient and the medical care personnel when pulling out the needle.
