A multifunctional blood type identification instrument

Abstract

The invention discloses a multifunctional blood group identification instrument, which is characterized by comprising a centrifugal chamber (1), a motor (2), a rotating shaft (3), a blood group card rotor assembly (4), a horizontal rotor assembly (5) and an angle rotor assembly (6); the rotating shaft (3) is arranged vertically, and the middle part of the rotating shaft (3) is rotatably connected to the bottom of the centrifugal chamber (1); the output end of the motor (2) is connected to the rotating shaft (3) The lower end is connected and used to drive the rotating shaft (3) to rotate; the upper end of the rotating shaft (3) is coaxially fixed with a spline shaft (3-1); the blood group card rotor assembly (4), the horizontal rotor assembly (5) ) and the angular rotor assembly (6) are located in the centrifugal chamber (1) and are sequentially mounted on the spline shaft (3-1) from bottom to top. The invention can realize multi-purpose of one machine, reduce equipment cost, and can select multiple functions at the same time or any one of them, and also avoid the problem that different rotors need to be disassembled and replaced during use.

Description

technical field [0001] The invention belongs to a multifunctional blood type identification instrument. Background technique [0002] The micro-column gel blood type test card (referred to as "blood type card") is simple and convenient, and the test results are fast and accurate. It has been widely used in European and American countries. With the advancement of medical science and technology in our country, microcolumn gel detection technology has been greatly developed in our country and widely used in major hospitals. [0003] The micro-column gel blood type test card adopts the principle of exclusion chromatography, that is, in the micro-column gel medium, the red blood cell antigen combines with the corresponding antibody to form a red blood cell immune complex, which cannot pass through the gel gap under a certain centrifugal force It floats on the surface of the gel or is suspended in the gel; if there is no corresponding antibody binding, the red blood cell immune c...

Problems solved by technology

However, at present, various instruments are required for medical operations. Due to the different centrifuged objects, different rotors are required, and there is a problem of incompatibility; if different rotors are replaced and disassembled, it is extremely inconvenient to use.
