Disposable safety acupuncture hemostix

Abstract

A disposable safe needling hemostix of medical equipment comprises of shell, needle, jacket and spring. It has the characteristics there are several convex bodies on the wall of jacket matching with sliding track on the outer wall of shell which appears periodically and the rising and falling parts of the front edge of the slope of radian of its lower edge is equal to that of the sliding track and is clustered on incisura of each sliding track, while the slope of radian of the upper edge is equal to that of the rising part; since the needle is embedded in the shell convex body and shrapnel of its back cover, and the lower edge of jacket extends out of the shell, the bottom of jacket must be touched when the needling hemostix is used. The jacket is pushed back, the convex body leaves away from the incisura along the rising part, and when withdraw of the needle, the spring at the back of jacket pushes the jacket downward, making the convex body falling onto the sliding track and is fixed in the final position, so that the whole jacket cannot retract, which eliminating infectiousness resulting from hurt by needle and assuring the disposable use.

Description

Technical field: [0001] The invention relates to an acupuncture blood collection device in a medical device, in particular to a blood collection device with a passively activated safety protection device for one-time use only. Background technique: [0002] With the gradual understanding of infectious pathogens, the majority of medical workers have realized the importance of using sharp medical instruments with safety protection devices to avoid bloodborne pathogen infection caused by punctures and cuts during the treatment process. Correspondingly, some blood collection devices with basic safety protection devices have been born on the market. Most of them are "active disposable" products, that is, after the operation is completed, the needle tip needs to be actively processed by hand, such as recapping. Put on the sheath, bend and blunt the needle, or retract the needle tip into the sheath, etc. In addition to the complicated operation of this active safety blood collectio...

Problems solved by technology

Correspondingly, some blood collection devices with basic safety protection devices have been born on the market. Most of them are "active disposable" products, that is, after the operation is completed, the needle tip needs to be actively processed by hand, such as recapping. Put on the sheath, bend and blunt the needle, or retract the needle tip into the sheath, etc. In addition to the complicated operation of this active safety blood collection device, it is still possible to process the needle tip for the second time. It is stabbed or cut before or during treatment, so its safety protection performance is not as good as that of the "passive disposable" blood collection device, that is, the safety protection device has been activated after the acupuncture operation is completed. Its needle tip has been automatically sealed, so that it no longer has the possibility of stabbing or cutting the human body immediately, and can guarantee the effect of only one use

At present, although there are some passive disposable safety blood collection devices in the international market, due to the limitation of the design structure, the volume is often much larger than the traditional ones, and the method of use is also different from the traditional blood collection devices. Because of the safety protection The device makes the needle body or knife body in it often unstable, which affects the clinical operation of blood collection, so it needs to be improved
