Problems solved by technology

[0003] However, this dressing cannot provide a moist environment for ophthalmology patients, which is not conducive to the formation of wound epithelial cells, the growth of granulation tissue, and wound healing; If the analysis process is not complete, it will cause certain harm to the human body. Studies have shown that ethylene oxide has certain carcinogenicity

Embodiment 1

[0025] (1) First, weigh 22% of starch, 51% of polyvinylpyrrolidone, and 27% of sodium carboxymethylcellulose for later use;

[0026] (2) Fully dissolve the components in step (1) into medical purified water that has been tested in advance and meets the standards. The dosage of medical purified water in this example is not strictly controlled, as long as the above components Just dissolve completely, and keep stirring the solution at a temperature of 90°C until the solution becomes a semi-gel state;

[0027] (3) irradiating the semi-gel state solution prepared in step (2) under an electron beam at a dose of 28 kGy to prepare a hydrogel with a three-dimensional network structure;

[0028] (4) Laminate the hydrogel prepared in step (3) with the non-woven base layer and the PE film to prepare the hydrogel eye patch.

Embodiment 2

[0030] (1) First, weigh 23% starch, 53% polyvinylpyrrolidone, and 24% sodium carboxymethylcellulose, and set aside;

[0031] (2) Fully dissolve the components in step (1) into medical purified water that has been tested in advance and meets the standards. The dosage of medical purified water in this example is not strictly controlled, as long as the above components Just dissolve completely, and keep stirring the solution at a temperature of 90°C until the solution becomes a semi-gel state;

[0032] (3) irradiating the semi-gel state solution prepared in step (2) under an electron beam at a dose of 30 kGy to prepare a hydrogel with a three-dimensional network structure;

[0033] (4) Laminate the hydrogel prepared in step (3) with the non-woven base layer and the PE film to prepare the hydrogel eye patch.

Abstract

The invention discloses a medical hydrogel eye mask. The medical hydrogel eye mask comprises a non-woven fabric base layer and a PE film; hydrogel is arranged between the non-woven fabric base layer and the PE film, and is composed of, by mass, 18 to 25% of starch, 50 to 55% of polyvinylpyrrolidone, 25 to 30% of sodium carboxymethylcellulose, and an enough amount of a solvent can be used for full dissolving of the other ingredients. According to a preparation method, moisture retention time can be prolonged to be as long as 24h via specific material matching; eye mask moisture retention time is ensured; under pathogen-free conditions, moist environment is beneficial for generation of wound surface epithelial cells; the medical hydrogel eye mask is capable of promoting growth of granulation tissue and healing of wound surfaces, preventing generation of incrustation or scars, and providing wound surfaces with the best moist environment; electron beams are used for sterilizing the medical hydrogel eye mask, so that pollution on the environment is reduced, the medical hydrogel eye mask is ensured to be sterile, and potential risk caused by incomplete degradation of oxirane is avoided.

Description

technical field [0001] The invention relates to a medical hydrogel eye patch and a preparation method thereof, in particular to a hydrogel eye patch suitable for ophthalmic surgery patients. Background technique [0002] After investigation and research, it is found that the dressings commonly used in ophthalmic surgery on the market are gauze sheets or non-woven dressings, and the sterilization method used is usually ethylene oxide sterilization. [0003] However, this dressing cannot provide a moist environment for ophthalmology patients, which is not conducive to the formation of wound epithelial cells, the growth of granulation tissue, and wound healing; If the process is not fully analyzed, it will cause certain harm to the human body. Some studies have shown that ethylene oxide has certain carcinogenicity. [0004] And the invention patent applied by our company is a medical hydrogel cold patch, the application number is: 201410190594.7. Although a medical hydrogel co...
