Embodiment Construction

[0016] The present invention provides, in an exemplary embodiment, a blood typing system comprising: a consumable roller comprising a polyester membrane, wherein the polyester membrane has holes to allow passage of individual red blood cells while simultaneously blocking the clotted blood complex; a liquid addition portion adapted to sequentially add a blood sample and reagents onto the consumable roller; and a mechanical portion mounted above the consumable roller adapted to manipulate the liquid addition part of the move.

[0017] Agglomeration is condensation between particles. In the presence of an agglutination-associated substance such as an antibody or other agglutination-associated substance, the agglutination-associated substance associates with multiple microparticles and joins them to form a microparticle complex that is larger than the individual microparticles. Therefore, observation of agglutination can be used as a method to identify specific antigens and thus ...

Abstract

The present invention discloses a blood typing system, including: a consumable roll including polyester membrane, wherein the polyester membrane has pores permitting individual red blood cells to go through while blocking agglutinated blood complexes; a liquid adding part, adapted to add blood specimen and reagent to the consumable roll, sequentially; and a mechanical part mounted above the consumable roll, adapted to manipulate movement of the liquid adding part. The present invention provides a simple system for blood type testing.

Description

technical field [0001] The present invention relates to blood group testing, and more particularly to a system for rapidly testing blood group. Background technique [0002] Many blood-related industries, such as blood donation, blood transfusion, raw material inspection of blood-derived products, etc., require related blood to be tested. Specifically, it is necessary to know the blood type associated with the presence or absence of inherited antigenic material on the surface of red blood cells (RBC). Hemagglutination, the clotting of RBCs in the presence of antibodies, is commonly used as a biological phenomenon in blood typing. [0003] Traditionally, blood typing is done manually. The test operator can mix the blood sample / specimen with the antibody on a glass slide, stir the mixture, wait for the incubation, and then observe the agglutination under the microscope. However, distinguishing agglutinated from nonagglutinated RBCs is very tricky, especially for untrained p...
