Embodiment

[0036] In the case of needing to separate blood, a blood separation device is required to separate blood cells and plasma in the blood. In a preferred embodiment of the present invention, for a smaller amount of blood separation, a hydrophilic epoxy-based material (i.e. epoxy A porous polymer layer 1 prepared from a resin polymer material), the porous polymer layer 1 is provided with communicating holes, and the pore diameter of the communicating pores is controlled at 2 μm, thereby blocking most of the blood cells in the blood, and filtering the plasma in the blood for use blood test.

[0037] The method for preparing the porous polymer layer 1 from the hydrophilic epoxy-based material is carried out by a reaction-induced phase separation method. Taking bisphenol A diglycidyl ether as an example, because the pore size of the interconnected pores of the porous polymer layer 1 is affected by the dosage ratio of bisphenol A diglycidyl ether and collagenase, and the reaction temp...

Abstract

The invention discloses a blood separating device. The device is a porous polymer layer prepared from hydrophilic epoxy-based materials, communicating holes are uniformly distributed in the porous polymer layer, so that when blood is injected, blood cells in the blood are blocked by the communicating holes, and plasma in the blood flows through the communicating holes. The invention further discloses a blood separation detecting device which comprises a second bracket, the blood separating device and a first bracket, and a blood separation detecting method. According to the invention, through the use of the porous polymer layer, blood separation is realized, the blood separation and blood detection are integrated together, a small amount of the blood can be detected, the devices disclosed by the invention have the advantages that the structures are simple, the costs are low, and the operations are convenient, so that the devices and the method are suitable for daily use.

Description

technical field [0001] The invention relates to the technical field of blood detection, in particular to a device for separating blood cells and plasma in blood, a blood separation detection device and a separation detection method. Background technique [0002] In recent years, with the change of living environment and resource conditions, many diseases caused by metabolism appear frequently and commonly appear in various populations, such as fatty liver, hyperuricemia, diabetes, etc. The diagnosis of these diseases can be obtained by examining the plasma in the blood to obtain the content of related substances. The inspection of plasma in blood generally involves separating the blood first, and then testing and analyzing the separated plasma. The most common is centrifuge separation. In the field of medical testing, the blood cell separator is used to separate the blood first, and then to test it. The principle of the centrifuge is mainly based on the fact that differen...
