Abstract
The invention relates to a disposable pricking-preventive blood collection needle which comprises a protective jacket, a blood collection needle tube and a guide tube. A pull-back device is arranged between the blood collection needle tube and the guide tube, and a pricking-preventive protective jacket sleeves the pull-back device. Two axial guide ridges are arranged on the outer side wall of the pull-back device, and two guide grooves which are in movable fit with the guide ridges are formed in the inner side wall of the pricking-preventive protective jacket. The disposable pricking-preventive blood collection needle has the advantages that self-latching grooves are formed in the guide ridges on the upper portion of the pull-back device, self-lock clamp protrusions which can be in snap fit with the self-latching grooves are arranged on the lower portion of the pricking-preventive protective jacket, a pull-back handle can be pulled down after blood is collected, and the self-latching grooves and the self-locking clamp protrusions are in snap fit with one another when the self-latching grooves in the upper portion of the pull-back device reach the self-locking clamp protrusions on the lower portion of the pricking-preventive protective jacket, so that the pull-back device and the pricking-preventive protective jacket can be automatically locked, the needle tube enters the pricking-preventive protective jacket, and the purpose of preventing pricking can be achieved.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically the anti-aculeus blood-taking pin of a kind of disposable use.
Background technology
At present, in to the blood collection procedure of sick body medical treatment, extensively adopt non-anti-aculeus blood-taking pin clinically, therefore after blood sampling in the collection of blood taking needle, transportation and processing procedure, slightly careless syringe needle will scratch medical personnel and relevant operator.
Summary of the invention
The object of the invention is to overcome the shortcoming of existing blood taking needle, a kind of blood taking needle with anti-acupuncture function is provided.
The present invention, comprises sheath, blood-collecting needle tube and conduit, between blood-collecting needle tube and conduit; be provided with withdrawing device, withdrawing device Zhou center is blood channel, and the upper end of blood channel connects blood-collecting needle tube; the lower end connecting duct of blood channel is arranged with anti-acupuncture protective sleeve on withdrawing device.
The present invention, in the lateral wall of withdrawing device, is provided with two and axially leads rib, in the medial wall of anti-acupuncture protective sleeve, be provided with two with described in lead the moving guide groove coordinating of rib.
The present invention, withdrawing device top lead rib place, be provided with self-locking catching groove, in the bottom of anti-acupuncture protective sleeve, be provided with the self-locking card convex being clasped with described self-locking catching groove.
The present invention, the top at withdrawing device, is provided with annular groove, on the top of anti-acupuncture protective sleeve, is provided with the bulge loop being clasped with described annular groove.Described annular groove and bulge loop form the counteracting force button bit of anti-acupuncture protective sleeve, effectively prevent piercing process withdrawing device retraction problems.
The present invention, on the right side of described anti-acupuncture protective sleeve, is provided with puncture hands handle; At the upside of described anti-acupuncture protective sleeve, be provided with concavo-convex anti-slip veins, be intended to make medical worker in puncture blood collecting process, to improve its operability.
The present invention; owing to leading rib place on withdrawing device top; self-locking catching groove is set; bottom at anti-acupuncture protective sleeve; be provided with the self-locking card convex being clasped with described self-locking catching groove, after blood sampling completes, the handle of pulling back of leaving behind; when the self-locking catching groove on withdrawing device top arrives the self-locking card convex position of anti-acupuncture protective sleeve bottom, protruding being clasped of self-locking catching groove and self-locking card automatically locks withdrawing device and anti-acupuncture protective sleeve.Needle tubing enters anti-acupuncture protective sleeve, thereby reaches anti-acupuncture object.
