Automatic blood sampling system as well as blood sampling equipment

Abstract

The invention discloses a blood drawing device, which comprises a test tube clamp part which clamps a blood-containing test tube, a blood lancet head clamp component which clamps a blood lancet head to move so as to insert into the test tube, and a drive component which fixes the test tube clamp part, and drives the test tube clamp part to clamp the test tube to move so as to shake the blood in the test tube. In addition, the invention also discloses an automatic blood drawing system. The device has the advantages of simple structure, practicability and easy operation; moreover, the device achieves blood drawing and blood shaking at the same time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic blood collection system and a blood collection device. Background technique [0002] Hospitals often collect blood when treating patients and saving lives. The way of blood collection changes with the development of science and technology. [0003] In the early stage of the development of medical devices, blood was collected by artificially applying pressure to the syringe, and the collected blood could not be shaken evenly while drawing blood, which affected the quality of blood; in addition, the amount of blood collected was judged by naked eyes, and it was difficult to guarantee the amount of blood collected. consistency. [0004] At present, vacuum blood collection tubes are used for blood collection, and the vacuum negative pressure in the vacuum blood collection tube avoids the act of artificially applying pressure to collect blood; the test tube and ...

AI Technical Summary

Problems solved by technology

The vacuum blood collection tube is designed according to the principle that the negative pressure in the tube is proportional to the blood collection volume. Therefore, the blood collection volume will vary due to the blood viscosity of the tester, the atmospheric pressure of the external environment (such as altitude) and the individual venous pressure. Insufficient or inaccurate blood collection; in addition, although the test tube containing blood can be manually shaken while collecting blood, in practical applications, multiple blood collections are often used. If you shake the tube or shake the test tube, it is easy to cause unnecessary situations such as blood coagulation due to uneven shaking.
