Novel indwelling needle supportive of single-hand puncturing and U-shaped lifting platform method fixing

Abstract

The invention discloses a novel indwelling needle supportive of single-hand puncturing and U-shaped lifting platform method fixing. The novel indwelling needle comprises a catheter, a rivet, a silicone catheter seat jacket, a catheter seat, an isolating plug, a push rod, a steel needle, a needle handle, a needle handle fixing column, an extension tube, a flow checking clamp, an infusion interface three-way seat, a needleless infusion joint and an end cap. By the novel indwelling needle, clinical puncture success rate is increased, one-time catheter indwelling success rate is high especially, damage to a vascular wall is reduced, clinical related complications are reduced effectively, and workload of nurses is lowered; puncture by two persons through cooperation is not needed, so that labor cost of hospitals is lowered. By the novel indwelling needle, occurrence rate of catheter blocking is reduced, indwelling time is prolonged, occurrence rate of pressure sores is lowered, the clinical related complications are reduced effectively, repeated puncture is avoided, working efficiency of the nurses is improved, and patients' satisfaction is improved; the novel indwelling needle is firm in fixing, so that accidental catheter extraction is avoided.

Description

technical field [0001] The invention relates to the technical field of indwelling needles, in particular to a novel indwelling needle that can be punctured with one hand and fixed by a U-shaped elevated platform method. Background technique [0002] Disposable venous indwelling needle products are clinically used for peripheral venous infusion and blood sample collection, and for short-term venipuncture and indwelling for drug infusion. After successful puncture, only the catheter made of polymer material is indwelled. Human veins and blood vessels, intravenous indwelling needles have become one of the most widely used puncture tools due to their characteristics of little irritation to blood vessels, can be indwelled for many days, reduce puncture pain for patients, and are easy to use. [0003] However, with the existing closed venous indwelling needles, the left hand is often used to hold and fix the patient’s upper arm puncture site during puncture. After blood returns, t...

Problems solved by technology

[0005] In order to overcome the defects of the above-mentioned prior art, the object of the present invention is to provide a new type of indwelling needle that can be punctured with one hand and fixed by the U-shaped elevated platform method, which can realize one-handed puncture while adopting the U-shaped elevated platform method to fix the structure Design; solves the problem of two-handed operation during clinical indwelling needle puncture, inserting the needle with one hand, sending the catheter to the blood vessel with one hand; after the puncture is completed, just rotate the extension tube 180 degrees above the puncture point to achieve U-shaped fixation , at the same time, the high-lift platform method is used to design the silicone block, and the high-lift platform method can be realized, and the U-shaped high-lift platform method can be completed in one step.
