Description
Technical Field
The invention relates to the technical field of blood centrifugation, in particular to a dual-mode blood centrifuge for a hospital clinical laboratory.
Background
Blood is a red opaque viscous liquid that flows in human blood vessels and the heart. The blood is composed of plasma and blood cells, wherein one liter of plasma contains 900-910 g of water, 65-85 g of protein and 20 g of low molecular substances, the low molecular substances contain various electrolytes and organic compounds, and the blood cells comprise three types of cells, namely red blood cells, white blood cells and platelets. The average life span of red blood cells is 120 days, the life span of white blood cells is 9-13 days, and the life span of platelets is 8-9 days. In general, 40ml of blood cells per person per day are senesced and dead. At the same time, a corresponding number of cells are newly formed.
The blood functions comprise two parts of blood cell function and blood plasma function, and have four functions of transportation, human body temperature regulation, defense, human body osmotic pressure regulation and acid-base balance. The main functions of the erythrocytes are to transport oxygen and carbon dioxide out, the main functions of the leukocytes are to kill bacteria, resist inflammation and participate in the process of immunity in vivo, the platelets mainly play a role in hemostasis in vivo, and the plasma functions mainly comprise nutrition, lipid transportation, buffering, osmotic pressure formation, participation in immunity, blood coagulation and anticoagulation.
Clinically, blood detection is a common detection means, mainly aims at clinical auxiliary diagnosis, and can also be used for physical examination, prenatal identification, immunological examination, special myelocytology detection, donor health screening, blood grouping, cross matching test and the like.
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.
However, most of the existing blood centrifugers commonly used adopt a disc design, test tubes filled with blood are circumferentially distributed on the disc, and the disc is driven by a servo motor so as to drive the test tubes to do circular motion and generate centrifugal force, but the centrifugal force still acts towards the center of a circle, and the centrifugal effect can improve the space.
