Problems solved by technology

In order to avoid the delayed rehabilitation of patients due to the occurrence of eye complications after surgery, causing additional pain and economic losses, nursing staff should take corresponding measures for eye care, which can effectively prevent and reduce the occurrence of exposure keratitis. The methods are roughly divided into: 1. Apply eye drops or ointments, such as tetracycline eye ointment, etc. This method needs to comply with standardized operations, consumes a lot of working time for nursing staff, and the drugs have certain toxic and side effects
2. Gauze dipped in normal saline to cover the patient's eyes, the moisturizing effect is poor, and the dry gauze needs to be replaced constantly. The normal saline can easily enter the patient's eyes, causing certain irritation and discomfort to the patient
3. Moisturizing eye patch, some medical eye patch products currently on the market, either the product transparency is not high enough, or the product is produced by irradiation, the risk factor is high, and the cost remains high
It is not conducive to the observation of nursing staff, but also increases the cost of patient treatment

Embodiment Construction

[0012] The main raw materials involved in the invention are polyvinyl alcohol (PVA), polyurethane (PU), collagen, sodium alginate, chitosan, water and the like. The medical hydrogel eye patch and one of the physical preparation methods involved in the present invention will be described in detail below with an example.

[0013] 1. Ingredients: Weigh 5-20g of PVA, 0.5-1.5g of chitosan, 100g of purified water, dissolve chitosan in water and add PVA.

[0014] 2. Heating and stirring: heat to above 60°C and mix the materials evenly until they become gelatinous.

[0015] 3. Filling: After cooling, the colloid is filled into the concave mold and leveled.

[0016] 4. Freezing: repeatedly freeze the mold filled with colloid 10 times at a temperature of -5°C to -60°C.

[0017] 5. Packaging: Take out the mold and thaw it out and pack it.

[0018] 6. Sterilization: After a confirmed sterilization process, the product is sterile.

Abstract

The invention relates to a medical auxiliary material and the technical field of the medical auxiliary materials, and in particular relates to a hydrogel eye mask which is used for moisturizing the eyes of general anesthesia surgery patients or deeply unconscious patients who are subjected to non-eye surgery and preventing exposure keratitis caused by eye interference and muscular flaccidity. The hydrogel eye mask meets the shape of the eye structure of people, is convenient to operate and use, and can provide relatively-long time moisture environment, and toxicity, sensitization and residues are avoided.

Description

technical field [0001] The invention relates to a medical auxiliary material and its technical field, in particular to a kind of eye moisturization for non-eye surgery patients under general anesthesia or deep coma patients and preventing exposed cornea caused by eye interference and muscle relaxation. Inflammatory hydrogel eye patches. technical background [0002] With the rapid development of medical science and technology, general anesthesia has been welcomed by the majority of surgeons due to its definite effect, quietness and comfort for patients, and has been promoted and applied clinically. However, when general anesthesia is performed, the patient is temporarily in a state of loss of consciousness. Due to the interaction between general anesthesia and muscle relaxants, the muscles of the patient, including the eye muscles, are relaxed, so that the patient cannot close the eyes; and when the anesthesia is too deep or prolonged During the anesthesia operation, the te...
