Example Embodiment

[0041] Example 1: Such as Figure 1 to Figure 3 As shown,

[0042] An HIV-specific plasma adsorption column, comprising: an adsorption column cavity 1 and resin particles 2 arranged in the adsorption column cavity 1 and made of macroporous strong basic styrene anion exchange resin;

[0043] A lithium heparin layer is attached to the inner wall of the adsorption column cavity 1, and the thickness of the lithium heparin layer is 0.5-1 mm;

[0044] A plurality of adsorption holes are distributed on the resin particles 2, and the pore size of each adsorption hole is 120.5 nm;

[0045] The two ends of the adsorption column cavity 1 are respectively connected with a blood tube 6.

[0046] The HIV-specific plasma adsorption column provided by the present invention is provided with resin particles 2 made of macroporous strong alkaline styrene anion exchange resin in a cavity. The resin particles are resin adsorption particles with alkali The sex groups are positively charged, HIV is negativel...

Example Embodiment

[0056] Example 2:

[0057] According to the above-mentioned embodiments, the present invention also makes the following improvements:

[0058] Both ends of the adsorption column cavity 1 are provided with a filter 3 through which plasma can pass, and a sealing cover 4 through which the resin particles 2 cannot pass. The sealing cover 4 is provided with a plasma inlet and outlet 5;

[0059] The filter screen 3 is wrapped around the two ends of the adsorption column cavity 1, the sealing cover 4 is arranged on the outermost of the two ends of the adsorption column cavity 1, and the inner wall of the sealing cover 4 and the adsorption column The outer wall of the cavity 1 is hermetically connected; the blood tube 6 is in communication with the plasma inlet and outlet 5 respectively.

[0060] In order to process the adsorption column cavity 1 at the same time, the resin particles 2 can be packed into the adsorption column cavity 1, and at the same time, the adsorption column cavity 1 can ...

Abstract

The invention relates to the field of medical instruments, and in particular to an aids virus specific plasma adsorption column and an application method thereof. The aids virus specific plasma adsorption column comprises an adsorption column cavity and resin particles, wherein the resin particles are prepared from macroporous strong-alkalinity styrene anion exchange resin; a heparin lithium layer which is 0.5-1 mm thick is adhered to the inner wall of the adsorption column cavity; a plurality of adsorption holes are distributed in the resin particles; the aperture of each adsorption hole is 120.5 nm; the two ends of the adsorption column cavity are respectively communicated with a blood catheter. The aids virus specific plasma adsorption column and the application method thereof provided by the invention can realize selective adsorption, effectively clean the plasma of aids patients, greatly increase the survival rate of the aids patients, prolong and save the lives of the patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an HIV-specific plasma adsorption column and a method for using the same. Background technique [0002] HIV stands for Human Immunodeficiency Virus. [0003] Human Immunodeficiency Virus (HIV), as the name suggests, causes a defect in the human immune system. Human immunodeficiency virus was first identified in the United States in 1981. It is a lentivirus that infects cells of the human immune system and is a type of retrovirus. A deadly infectious disease for which there is currently no effective treatment. The virus destroys the immune ability of the human body, causing the immune system to lose its resistance, which leads to the survival of various diseases and cancers in the human body, and eventually leads to AIDS (acquired immunodeficiency syndrome). [0004] Status of the virus: It has killed nearly 12 million people worldwide and infected more than 30 million. [0005...
