Counter-force slow-descending anti-hemolysis blood sample collection equipment for physical examination center

Abstract

The invention discloses counter-force slow-descending anti-hemolysis blood sample collection equipment for a physical examination center, which comprises a supporting seat and a sample collection box body at the upper part of the supporting seat, access placement cavities are formed in the side wall of the sample collection box body in an array manner, and magnetic rotation control grooves are formed in the upper walls of the interiors of the access placement cavities; the magnetic turning self-dumping type blood sampling storing and taking mechanism is arranged in the storing and taking placing cavity in a drawing manner; the eddy-current damping slow-descending uniform-mixing anti-coagulation mechanism is composed of an eddy-current slow-lifting circulating assembly and rotary anti-coagulation circulating uniform-mixing assemblies, the rotary anti-coagulation circulating uniform-mixing assemblies are symmetrically arranged on the two sides of the sample collection box body, and the two symmetrically arranged rotary anti-coagulation circulating uniform-mixing assemblies are connected together through the eddy-current slow-lifting circulating assembly. The invention belongs to the field of blood collection, and particularly relates to counter-force slow-descending anti-hemolysis blood sample collection equipment for a physical examination center, which enables collected blood to slowly flow down along a tube wall and to be slightly reversed and shaken up so as to avoid blood hemolysis.

Description

technical field [0001] The invention belongs to the technical field of blood collection, and specifically refers to an anti-hemolytic blood sample collection device for an anti-force slow-down physical examination center. Background technique [0002] A medical examination center refers to a place that checks the health of the human body, has complete equipment and manpower, and can check out physical diseases and health assessments. In the process of physical examination, blood collection is required. Improper operation of blood collection will cause blood hemolysis. Blood hemolysis refers to the abnormal rupture of red blood cells and white blood cells during the collection, anticoagulation, storage and transmission of blood samples. If a blood sample is hemolyzed, some substances in the red blood cells will be released, resulting in abnormal test results, which will affect the accurate judgment of the clinician on the test results. Therefore, when the sample is moderately...

Problems solved by technology

[0005] 2. When the anticoagulant tube is mixed with the anticoagulant, the shaking method is wrong or the amplitude is too large (the blood sample is subjected to too much impact pressure, which destroys the blood cells);

[0007] 3. Do not shake well in time when using dry powder blood collection tubes (dissolution contact surface is not balanced, interface temperature is too high, heat of dissolution or reaction occurs);

[0009] 4. The vacuum negative pressure of the empty vacuum blood collection tube is relatively large. At the beginning of blood collection, the blood flows to the bottom of the tube quickly, and the collision of red blood cells can cause rupture, and hemolysis can be seen clinically;
