Embodiment 1

[0029] like figure 1 As shown, the stem cell filter includes a frame body 1 and a mesh body 2, and the mesh body 2 is connected to one side of the frame body 1.

[0030] The frame body 1 is connected with a clamping portion 3 .

[0031] The frame body 1 and the net body 2 are detachably connected.

Embodiment 2

[0033] On the basis of implementing 1, the present embodiment provides a kind of preparation method of nano-silver coating of stem cell filter, comprising the following steps:

[0034] S1. prepare the silver target according to the size of the stem cell strainer;

[0035]S2. The silver target is arranged on both sides inside and outside the magnetron sputtering vacuum chamber, the silver target arranged in the magnetron sputtering vacuum is the inner target, and the silver target arranged outside the magnetron sputtering vacuum is Outer target; place the stem cell filter on the inner target, then close the vacuum chamber, and finally evacuate the vacuum chamber;

[0036] S3. Input an inert gas into the magnetron sputtering vacuum chamber in the above step S2;

[0037] S4. Using the magnetron sputtering method to form a nano-silver film on the surface of the stem cell filter through the internal target to obtain the initial product;

[0038] S5. Utilize the chemical precipita...

Embodiment 3

[0040] On the basis of implementing 1, the present embodiment provides a kind of preparation method of nano-silver coating of stem cell filter, comprising the following steps:

[0041] S1. Use the method of high-frequency oscillation to clean the stem cell filter. The stem cell filter is supported by high-molecular polymers with anti-cell adsorption, such as polyethylene oxide or PEO-like polymers. Then prepare the silver target according to the size of the stem cell strainer;

[0042] For the size of the stem cell filter, take the largest three-dimensional diameters a, b, and c, and place the amorphous object in a steady state, and take the largest three-dimensional diameter under horizontal conditions. Customized silver targets. The volume of the silver target is represented by V, V=1.2a×1.2b×1.2c. The volume of the silver target is represented by V, V=1.2a×1.2b×1.2c.

[0043] S2. The silver target is arranged on both sides inside and outside the magnetron sputtering vac...

Abstract

The invention belongs to the technical field of medical apparatus and instruments, and discloses a stem cell filter screen and a preparation method for a nano-silver coating based on the stem cell filter screen. According to the stem cell filter screen and the preparation method, an outer coating layer is formed on the stem cell filter screen by using a magnetron sputtering method, and an inner coating layer of the stem cell filter screen is realized by using a chemical auxiliary deposition growth method. The stem cell filter screen and the preparation method have the advantages that the magnetron sputtering and chemical deposition methods are used for forming the coating layers inside and outside the stem cell filter screen, so that the stem cell filter screen has excellent characteristics of nano-silver; the adopted nano-silver can efficiently kill hundreds of pathogenic microorganisms; microcirculation of tissues around a wound is improved, wound healing is effectively promoted, repair and regeneration of damaged cells are promoted, and inflammatory response is eliminated; the growth of damaged tissue cells is effectively activated and promoted, the generation of scars is reduced, and wound healing is accelerated. and the stem cell filter screen has super-strong permeability, belongs to a non-antibiotic bactericide, and overcomes many defects of antibiotic sterilization.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a stem cell filter and a method for preparing a nano-silver coating based on the stem cell filter. Background technique [0002] Nanometer (nm) is the smallest unit of measurement after the micron in the physics world, with the development of nanotechnology. A large number of nanomaterials have been found to have antiphysical phenomena. As well as the quality and effect of special functions, nano-silver is also after the extensive development of metal nano-materials. an emerging field of research. Silver in the nanometer state has produced a qualitative leap in the bactericidal ability used in biomedicine. A very small amount of nano-silver can produce a powerful bactericidal effect that was unimaginable in the past. Nano-silver can kill more than 650 kinds of bacteria in a few minutes. It can promote the growth of cells, the repair of damaged cells, and t...
