Problems solved by technology

However, due to its large molecular weight, it is not easy to enter cells, and the effect of scavenging free radicals is not significant, so its clinical application is limited; 2. Non-enzyme oxygen free radical scavenging drugs: common vitamin compounds, coenzyme Q10, manna Alcohol, fructose 1-6-diphosphate, flavonoids, peptide compounds, lipoic acid, metal selenium, etc.; traditional Chinese medicine preparations such as red ginseng quinone, ginsenoside, etc., but the oxygen free radical scavenging speed is slow, not suitable for medical clinical use

Embodiment 1

[0026] like Figure 1 to Figure 6 As shown, a plasma filter for adsorbing oxygen free radicals includes a cylindrical housing 10, the housing 10 includes a main body 11 for accommodating the filter element, and an upper cover installed on the upper end of the main body 11 for compressing the filter element 12. The upper cover part 12 is respectively provided with an air filter port 13 installed with a high-temperature air filter membrane, and a liquid inlet port 14; the lower end of the main body part 11 is provided with a liquid outlet port 15.

[0027] A filter element made of a positively charged membrane is installed in the housing 10 , and the filter element includes a roll filter element 2 near the liquid inlet 14 and a flat filter element 3 near the liquid outlet 15 . The spiral filter element 2 is formed by rolling a layer of positively charged nylon membrane 20 . Several guide rods 21 are inserted into the roll filter element 2 along the flow direction. Hemispheric...

Abstract

The invention discloses a plasma filter capable of adsorbing OFRs (oxygen free radicals) and belongs to the field of health care. The plasma filter comprises a casing, wherein a liquid inlet and a liquid outlet are arranged at two ends of the casing respectively; filter elements made from positive charge films are mounted in the casing and comprise a roll type filter element close to the liquid inlet and a planar filter element close to the liquid outlet. The plasma filter adopts the manner of adsorbing plasma through the positive charge films and can directly and quickly remove the OFRs in blood, through combination of the roll type filter element and the planar filter element, plasma is smooth, the filtering surface area is further increased, and the filtering effect is improved. The plasma filter is arranged in an in-vitro plasma adsorbing system and can be medically clinically used conveniently and efficiently, and a new treatment method is provided for quick solution of acute inflammatory reactions.

Description

technical field [0001] The invention relates to consumable products in the field of biomedicine, in particular to a plasma filter for absorbing oxygen free radicals. Background technique [0002] Most of the purification membranes used in the existing hemodialysis are cellulose acetate copper fen, polyacrylonitrile, polysulfone and their derivatives. Blood flows through one side of the dialysis membrane, and on the other side of the membrane, dialysate circulates. Due to the concentration difference on both sides of the membrane, metabolites in the blood, such as urea, creatinine, and electrolytes, pass through the dialysis membrane by diffusion and enter the dialysate. [0003] In other fields of blood extracorporeal circulation, the filtration of blood components and the development of new membrane materials have always been the focus of research, but the current products in the field of plasma purification have not removed oxygen free radical inflammatory mediators in bl...
