Abstract

The invention provides a mixing method and a mixing apparatus for particle agglutination. A mixing method for particle agglutination includes the following steps of: dropping testing materials into anaccommodating recess at one end of a channel structure; pressing a flexible layer on the other end of the channel structure; and releasing the flexible layer to an initial position after pressing theflexible layer such that a negative pressure is generated by an air chamber that is covered by the flexible layer and draws the testing materials that are in the accommodating recess to move toward the air chamber along a diverging channel of the channel structure. The testing materials are mixed with each other in the diverging channel, in which the depth of the diverging channel is gradually increased from the accommodating recess to the air chamber.

Description

technical field [0001] The invention relates to a particle agglutination mixing method and a particle agglutination mixing equipment. Background technique [0002] Currently, there are roughly three methods for determining blood type by mixing blood and antibodies, including the immediate centrifugation method in test tubes, the solid-phase microwell plate method, and the gel column agglutination method. Immediate centrifugation of the test tube is to mix the blood and antibody in the test tube. If the blood clots, it will aggregate into blood clots and deposit at the bottom of the test tube. However, when using the test tube immediate centrifugation method for blood group testing, the sample needs to be pre-treated, such as centrifugation, washing and dilution steps, which not only takes a long time for the overall test, but also requires sufficient blood volume and antibody dose to ensure a smooth test. [0003] In addition, the solid-phase microwell plate method is to pl...
