Disposable safe blood collector

Abstract

The invention discloses a disposable safe blood collector, consisting of a rubber sleeve, a needle seat, a puncture needle, a spring and an outer sleeve, wherein the needle seat is bonded in the middle of the puncture needle; the rubber sleeve is arranged on the needle seat and covers one end of the puncture needle; the spring is sheathed on the spring outer sleeve at one side of the puncture needle; the rubber sleeve, the needle seat, the puncture needle and the spring are all arranged in the outer sleeve. When the disposable safe blood collector is in use, a handle on the needle seat is pushed by a hand so that the puncture needle extends forwards out of the outer sleeve and the extension position is maintained, at this moment, the spring is compressed, blood collection work can be started, when the blood collection is finished and the puncture needle is pulled out of a patient body, the handle on the needle seat is triggered by a hand to unlock a latch between the handle and the outer sleeve; and then, under the action of the restoring force of the spring, the rubber sleeve, the needle seat and a puncture needle combined body move backwards and return into the inner cavity of the outer sleeve completely.

Description

technical field [0001] The invention relates to a medical blood collection device, which is a disposable safe blood collection device with the function of blood collection. technical background [0002] The disposable safety blood sampling device of the present invention is mainly used for medical purposes. Through the puncture technique, the patient's blood sample is collected into a specific container, which plays a huge role in the process of laboratory testing and disease treatment. Missing medical equipment. However, with the development of natural diseases and the mutation of viruses and bacteria, cross-infection and disease transmission caused by contact with blood or body fluids are becoming more and more serious (such as: common or repeated use of injection equipment by drug addicts, resulting in rapid spread of diseases, In addition, in daily medical behaviors, iatrogenic infections caused by injections aimed at medical staff due to needle stick injuries are also ...

AI Technical Summary

Problems solved by technology

[0003] 1. The blood collection device is directly integrated with the blood collection tube, which seems to be an improvement on the surface, but in fact it will not be able to meet the operational needs of collecting multiple blood samples at one time

[0004] 2. It is necessary to use a special component (inner jacket or fixed retaining ring) to start the protective action of the puncture needle, so the structure is complicated

[0005] 3. It is necessary to re-protect unused puncture needles, that is, to increase the components of the device, and to increase the operation link for medical staff to remove the puncture needle protective cap

[0006] Therefore, at present, there is no technical solution for a single-use blood collection device with a simpler structure, easier manufacture and more convenient operation in China.
