Blood mixer for blood routine test

Abstract

Relating to the technical field of medical instruments, the invention discloses a blood mixer for blood routine test. The blood mixer includes a fixed base, an engine is fixedly installed at the top of the fixed base inner cavity, two ends of the engine are both provided with output shafts, and the two output shafts of the engine are fixedly connected to couplings and connecting rods thereof. Theblood mixer for blood routine test injects a collected water sample into middle inner cavities of blending pipes through liquid inlet holes, during synchronous period constant-speed rotation of the blending pipes and a blending base plate, a part of the internal blood sample can be adsorbed to the outer walls of traction members, when the concentration of the blood sample increases with time, retardation can occur during flow, and part of the blood sample contacting the traction members can pull the traction members to one side, the pressure of limiting partition boards on elastic elements increases gradually with time, pressure detection devices can achieve instant monitoring, and the blood sample with too high coagulation degree (and unsatisfactory activity) can be abandoned, thus 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
