Needle stick injury prevention type venous indwelling needle

Abstract

The invention discloses a needle stick injury prevention type venous indwelling needle, and relates to the technical field of venous indwelling needles. The needle stick injury prevention type venous indwelling needle comprises a pipe sleeve seat, the upper end of the pipe sleeve seat fixedly communicates with a sleeve, an elastic sealing plug is installed on the inner wall of the pipe sleeve seat, a first abutting block and a second abutting block are fixedly connected with the inner wall of the pipe sleeve seat, and an elastic piece is installed on the upper surface of the second abutting block. A safety needle is fixedly connected with seat lower surface end of the steel needle, a safety clamping sleeve abuts against the upper surface of the safety needle seat, a fixing plate is installed on the inner wall of the safety clamping sleeve, a fixing groove for the steel needle to penetrate through is formed in the surface of the fixing plate, and a flat ring is installed on the surface of the steel needle. A shrunk sealing opening is blocked by arranging the elastic piece, meanwhile, the end of the steel needle abuts against the shrunk sealing opening, and the situation that the body of a patient is prevented from being punctured by the needle head under the condition that the medicine is injected for a long time; and meanwhile, the condition that a doctor is accidentally injured by the injection needle when operating the device is further prevented.

Description

technical field [0001] The invention relates to the technical field of venous indwelling needles, in particular to a needle-puncture-proof venous indwelling needle. Background technique [0002] The cannula of the venous indwelling needle is guided into the veins of the human body by a puncture needle. Therefore, after the cannula is punctured in place, the guiding puncture needle needs to be withdrawn and discarded. During this process, it is very easy to be withdrawn if the doctor is not careful puncture needle wound. Contents of the invention [0003] The purpose of the present invention is to provide a kind of anti-needle venous indwelling needle, which has the ability to block the reduced sealing port by setting the shrapnel, and at the same time hold the end of the steel needle against it, so as to prevent the patient from injecting for a long time. In the case of medicine, the body will be stabbed by the needle, and at the same time, it will prevent the doctor from...
