Abstract

The invention discloses a micro blood cell separation device and a method for using the same. The separation device comprises a signal generator, a sample-adding pump, a separation chip and separated cell collectors; a separating cavity is arranged on the separation chip; the front end of the separation cavity is provided with an infusion opening; the rear end of the separation cavity is provided with two outlets; an electrode plate is arranged in the separation cavity; interdigital electrode groups are arranged on the electrode plate; the signal generator is connected with the interdigital electrode groups through conducting wires; the sample-adding pump is communicated with the infusion opening through a sample infusion pipe; and the outlets are connected onto the separated cell collectors. According to the invention, the separation is carried out by using the dielectrophoresis characteristic differences of blood cells in an electric field; and the continuous separation manner has the advantages of high efficiency, low cost, little cell damage, capability of large-flux separation and the like compared with the traditional cell separation method.

Description

Technical field: [0001] The invention relates to a miniature blood cell separation device and a using method thereof. A kind of blood cell separation using dielectrophoresis method, which can be used for continuous large-throughput separation. It has the advantages of simple structure, high separation efficiency, and small cell damage. It can be used in various fields such as medical diagnosis, biological reaction, and health quarantine. . Microseparation chip and method of use thereof. Background technique: [0002] Cell separation is an essential link in applications such as biochemical detection and medical diagnosis. Commonly used methods include filtration, adsorption-release, and magnetic separation. In the filtration method, the sample cells are passed through a filter, a filter screen, and a filter membrane of a specific size under pressure, and the separation process of cells of different sizes is realized by selecting the filter size. The adsorption release meth...
