Automatic peripheral blood collecting and prediluting machine and matched blood sampling tube thereof

Abstract

The invention discloses an automatic peripheral blood collecting and prediluting machine and a matched blood sampling tube thereof. The automatic peripheral blood collecting and prediluting machine consists of a matched blood sampling tube moving device, a matched blood sampling tube rotating and lifting device, a blood collecting peripheral limiting device, an integrated controller, a multimediaalternating device and the like. A sponge cushion for disinfection, a disposable spring puncturing needle device, a blood sample collecting cavity, a hose clamping and closing spring, a cutting bladedevice, a blood sample diluting cavity and the like are integrated on the matched blood sampling tube. Through the adoption of the automatic peripheral blood collecting and prediluting machine and thematched blood sampling tube thereof disclosed by the invention, works of peripheral location disinfection, puncturing, blood sample collecting, quantitative blood sample diluting can be automaticallycompleted, so that the labor intensity of medical workers is reduced, and the error of manual operation is reduced to a certain degree; the matched Blood sampling tube combines the functions of disinfecting, puncturing, collecting, cutting and diluting, and five function regions are independently separated, so that the space required by blood collecting is saved, and besides, cross-infection is also avoided.

Description

technical field [0001] The invention belongs to the field of biomedical equipment, and in particular relates to an automatic peripheral blood collection and pre-dilution machine controlled by PLC and its matching blood collection tubes, which are used in medical institutions to collect a small amount of peripheral blood required and pre-dilution with a diluent. Background technique [0002] Nowadays, the peripheral blood collection method in medical institutions is usually the way of manual disposable puncture needle or the way of using glass capillary or bullet to collect blood after laser irradiation puncture. These two peripheral blood collection methods not only have the problems of heavy workload, low blood collection efficiency, and time-consuming and labor-intensive problems, but also have the problems of strong pain for patients in manual puncture, and less bleeding in laser puncture. [0003] In addition, at present, the peripheral blood needs to be diluted by a cer...

AI Technical Summary

Problems solved by technology

These two peripheral blood collection methods not only have the problems of heavy workload, low blood collection efficiency, and time-consuming and labor-intensive problems, but also have the problems of strong pain for patients in manual puncture, and less bleeding in laser puncture.

[0003] In addition, at present, the peripheral blood needs to be diluted by a certain proportion in advance due to the small amount of blood collected after collection, so that it can be detected in batches by detection instruments, so that the subsequent dilution work will not only further increase the workload of talented personnel, but also The stability of artificial dilution is not high, and large errors are prone to occur, which will affect the final test results
