Abstract
The utility model belongs to the technical field of medical instruments, and provides a remaining needle preventing puncture. The remaining needle comprises accessories of a sheath, a catheter, a needle core, a seal element, a needle seat (single wing), a needle tube, a catheter seat, a flexible hose, a hose clamp, an anti-microbial cover cap, a transfusion connector, a positive pressure connector and a puncture prevention device. The remaining needle preventing puncture is characterized in that the detachable puncture prevention device is installed at the rear end of the catheter seat, the puncture prevention device is divided into three parts of a clamp rod part, a clamp ring part and a guide sleeve part. One end of the clamp rod part is fixed in a needle seat rear hole, a clamp position is arranged at the other end of the clamp rod part, and the clamp position is conveniently clamped into the clamp ring to have a limit function. One end of the clamp ring part is connected with the tail end of the guide sleeve through a clamp hole, the other end of the clamp ring part is of a clamp jaw type to be conveniently fixed and limited with the clamp position on a clamp rod, and a guide groove is arranged on the guide sleeve part. The remaining needle preventing puncture is convenient to produce and assemble and can protect the sharp needle tube after the remaining needle is used so as to prevent medical personnel and others from being punctured.
Description
Technical field
This utility model product relates to the medical apparatus and instruments articles for use, relates in particular to for human body to carry out the venous detaining needle that venous transfusion, blood transfusion etc. are used.
Background technology
Remaining needle generally is used for clinically to patient's infusion medicinal liquid, because it has the vascular puncture of minimizing number of times, reduces sepage, and can carry out quick infusion medicinal liquid, is conducive to alleviate the advantages such as the painful and convenient rescue of patient.
Therefore but after the shortcoming of existing remaining needle is venipuncture, needle tubing is pulled out, outside the sharp needle tubing after the use can be exposed to, clearing up, when destroying retention needle tube, being easy to stab medical personnel or other people, caused cross infection.At present; anti-acupuncture remaining needle be increased by one on the basis of common remaining needle in the past can Needlestick prevention device; after remaining needle uses; Needlestick prevention device can effectivelyly not expose sharp needle tubing protection, prevents fundamentally that therefore medical personnel are punctured the generation of pricking wound and the event of infection.
Summary of the invention
The purpose of this utility model provides a kind of anti-acupuncture remaining needle, has security performance good; easy to operate; after venipuncture, then along the guide groove withdraw of the needle, needle tubing slides in guide pin bushing with needle stand; when sliding into rear end of conducting sleeve; the screens of kelly part snaps in the snap ring, thus the spacing effect of playing moving-limiting, and needle tubing is stable fixing; and this moment, needle tubing was also protected in guide pin bushing fully, thereby avoided stabbing medical personnel or other people because needle tubing exposes.
The purpose of this utility model is achieved in that a kind of anti-acupuncture remaining needle, and it comprises: sheath, needle tubing, conduit, nook closing member, sealing member, needle stand, catheter block, pipe clamp, flexible pipe, fungi-proofing block, infusion connector, positive pressure connector and Needlestick prevention device.It is characterized in that in the catheter block rear end separable Needlestick prevention device being housed, Needlestick prevention device is divided into three parts, is respectively the kelly part, snap ring part and guide pin bushing part.Kelly part one end is fixed in the needle stand metapore, and the other end is provided with screens, and screens is convenient to snap in and is played position-limiting action in the snap ring; Snap ring part one end is connected to the guide pin bushing end by hole clipping, the other end be the claw pattern be convenient to kelly on screens be fixed spacing; Be provided with guide groove on the guide pin bushing part; being convenient to remaining needle uses in the withdraw of the needle process; needle tubing slides in the guide groove cover with needle stand; when sliding into rear end of conducting sleeve; the screens of kelly part snaps in the snap ring; thereby the spacing effect of playing moving-limiting, this moment, needle tubing was also protected in guide pin bushing fully, thereby avoided stabbing medical personnel or other people because needle tubing exposes.
Adopted above-mentioned technical solution; after remaining needle uses; can make its exposed needle tubing snap in snap ring by the screens on the kelly; thereby play steady locking position-limiting action; needle tubing is protected fully in guide pin bushing; realize safety, avoid stabbing medical worker or other people, reduce cross infection and pollution.
Below in conjunction with drawings and Examples this utility model product is further described.
