Description

Clinical laboratory blood centrifuge

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to clinical laboratory blood centrifuge.

Background

When the clinical laboratory uses blood to test various physiological indexes, a blood centrifuge is needed to firstly layer the blood, and then the required blood components are used. The human blood is called as whole blood after anticoagulation treatment, and the whole blood is mainly divided into three layers after centrifugation, namely a plasma layer, a leucocyte layer and a red blood cell layer from top to bottom in sequence. The plasma layer mainly comprises plasma, water, protein, salts, various ions and the like; the tunica albuginea layer mainly comprises a platelet-rich region, a lymphocyte-rich region, a monocyte-rich region and a granulocyte-rich region, and the specific gravities of the tangible cells are approximate, so that the cells are gathered in the tunica albuginea layer; the red blood cell layer can be simply divided into young red blood cells and normal red blood cells, which have slightly different specific gravities because they are in different stages of red blood cell growth. According to the principle of layering after whole blood centrifugation, different blood components in each layer can be separated and prepared into component blood, so that blood resources can be reasonably utilized, the requirements of patients on different component blood are met, and the treatment effect is improved.

At present, the centrifuge that the clinical laboratory used adopts the disc design, and the test tube circumference that is equipped with blood distributes on the disc, and the disc is then driven by servo motor to drive the test tube and be circular motion, produce centrifugal force, but this kind of centrifugal force effect still faces the centre of a circle of disc, and centrifugal effect is poor, and then has reduced the centrifugal effect of blood. In view of the above drawbacks, it is actually necessary to design a clinical laboratory blood centrifuge.
