A blood mixer for routine blood tests

Abstract

The invention relates to the technical field of medical devices, and discloses a blood mixer for routine blood tests, which includes a fixed base, an engine is fixedly installed on the top of the inner cavity of the fixed base, and output shafts are provided at both ends of the engine , the output shafts of the two engines are fixedly connected with couplings and connecting rods thereof. The blood mixer for routine blood tests injects the collected blood sample into the middle cavity of the mixing tube through the liquid inlet hole. Adsorbed on the outer wall of the traction piece, when the blood sample concentration gradually increases with time, it will block when flowing, and the part of the blood sample that is in contact with the traction piece will pull the traction piece to one side, increasing the elasticity of the limit partition over time The pressure of the element gradually increases, which can be monitored in real time by the pressure detection device, and blood samples with excessive coagulation (and activity that do not meet the requirements) are discarded, thereby improving the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood mixer for routine blood tests. Background technique [0002] Routine blood tests are often used as an auxiliary means of disease diagnosis. The main inspection items include red blood cell count, white blood cell count, platelet count, and hemoglobin content. Doctors can preliminarily determine the patient's condition by interpreting blood test data. When the laboratory tester collects blood, he usually uses a purple cap blood routine tube to take four to five milliliters of venous blood. The inner wall of the blood routine tube will be sprayed with EDTA reagent, which can chelate with calcium ions in the blood to prevent The collected blood is coagulated, so it needs to be shaken and mixed quickly after blood sampling. Existing medical institutions generally use blood mixers to process blood samples, but most of these mixers have complex structures, high failure ...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a blood mixer for routine blood tests, which has the advantages of a simple structure, but can fully mix blood samples for routine blood tests, and can detect the coagulation degree of blood samples in real time, and solves the problem of Most of the existing blood mixers are complex in structure, high in failure rate, inconvenient for maintenance and unable to detect the degree of blood coagulation in real time
