Medical hydrogel eye patch

Abstract

The invention provides a medical hydrogel eye patch, which is composed of a medical non-woven fabric and a gel composition. The gel composition is made of the following components according to the weight percentage: 0.5-0.6% w / carrageenan w, konjac gum 0.4-0.5%w / w, CaCl2 0.05-0.1%w / w, KCl 0.3-0.4%w / w, and the balance is purified water. The invention has the following technical effects: A. Good biocompatibility, no sensitization, no stimulation, no toxic and side effects. B. Good moisture retention, keeping the eyes in a relatively closed humid environment (relative humidity above 80%, lasting 8-12 hours / sticker). C. High comfort, moderate adhesion to eye skin, high degree of closeness, and will not stick to human hair. D. There is no residue after use, and there is no need to wash the patient's skin and hair. E.

Description

technical field [0001] The invention relates to a medical hydrogel eye protection patch, which belongs to the technical field of medical dressings. Background technique [0002] Medical dressings are medical products used for skin injuries. In the past, the interpretation of medical dressings was: "the general term for gauze, cotton balls or cotton pads used to clean or protect wounds". When treating a patient's wound, it is necessary to cover the wound with a dressing after removing necrotic tissue to prevent bacterial invasion and control water loss. Nowadays, with the development of science and technology, people put forward new evaluation indicators for medical dressings: (1) can control and absorb exudate; (2) can provide a bacterial barrier, create a good environment suitable for tissue growth, and promote Tissue growth; (3) Appropriate gas and water vapor permeability; (4) Easy to use and easy to remove; (5) Non-toxic, harmless, and non-irritating; (6) Good mechanic...

Problems solved by technology

[0007] Erythromycin eye ointment is very viscous, it is not easy to apply evenly, and part of the conjunctiva is not protected, which leads to the failure of intraoperative prevention; squeezing the eyeball during the application process may also cause corneal and conjunctival damage. One erythromycin eye ointment is given to different patients repeatedly use, it is also easy to cause cross-infection

However, aseptic application or adhesive tape can cause skin allergies around the eyes. When the adhesive tape is removed, it is easy to cause skin damage around the eyes, etc.
