Embodiment 1

[0041] Embodiment 1: 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 strongly basic styrene-based anion exchange resin;

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

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

[0045] Both ends of the adsorption column cavity 1 are respectively connected with blood conduits 6 .

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

Embodiment 2

[0057] According to above-mentioned embodiment, the present invention has also made following improvements:

[0058] Both ends of the cavity 1 of the adsorption column are provided with a filter screen 3 and a sealing cover 4 through which the plasma can pass, but the resin particles 2 cannot pass through, and 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 sides of the two ends of the adsorption column cavity 1, the inner wall of the sealing cover 4 and the adsorption column The outer wall of the cavity 1 is sealed and connected; the blood conduits 6 communicate with the plasma inlets and outlets 5 respectively.

[0060] In order to process the cavity 1 of the adsorption column, the resin particles 2 can be loaded into the cavity 1 of the adsorption column, and the cavity 1 of the adsorption column can be sealed well...

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...
