Embodiment 1

[0020] In this example, the mass percentages of the components required to prepare the gel are shown in Table 1.

[0021] Weigh glycerin, polyvinyl alcohol, sodium alginate, carrageenan, and sodium hyaluronate according to the formula and mix them evenly. After adding water, heat them in a glue tank to 85°C, stir for 90 minutes, and cool to 40°C at room temperature to obtain a gel Gel paste: press filter the prepared gel paste to the coating cutting machine, then spread it on the non-woven fabric, and then cover the gel layer with polypropylene film, die-cut the gel to get the semi-finished eye patch , Co60 irradiation sterilization.

Embodiment 2

[0023] In this example, the mass percentages of the components required to prepare the gel are shown in Table 1.

[0024] Weigh glycerin, polyvinyl alcohol, sodium alginate, konjac gum, and sodium hyaluronate according to the formula and mix them evenly. After adding water, heat them in a glue tank to 80°C, stir for 90 minutes, and cool to 40°C at room temperature to obtain a gel Gel paste: press filter the prepared gel paste to the coating cutting machine, then spread it on the non-woven fabric, and then cover the gel layer with polypropylene film, die-cut the gel to get the semi-finished eye patch , Co60 irradiation sterilization.

Embodiment 3

[0026] In this example, the mass percentages of the components required to prepare the gel are shown in Table 1.

Abstract

The invention discloses a medical cold compress gel eye pad and a preparation method thereof, the eye pad sequentially comprises a non-woven fabric layer, a gel layer and a polypropylene film from bottom to top, and gel in the gel layer is prepared from polyvinyl alcohol, glycerin, a thickening agent, sodium hyaluronate, sodium alginate and water. The eye pad is used for being pasted outside eyes of a general anesthesia operation patient or a deep coma patient, provides a relatively closed humid environment for the patient, protects the eyes from external stimulation and is easy to uncover and paste. The preparation method provided by the invention can shorten the production time and improve the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, and in particular relates to a medical cold compress gel eye patch and a preparation method thereof. Background technique [0002] Patients undergoing general anesthesia and deep coma, due to the effect of anesthetic drugs, the central nervous system of the surgical patients is inhibited, they are in an unconscious state, their muscles are flaccid and weak, their protective reflexes disappear or weaken, and they basically lose their ability to self-regulate, resulting in eyelid eczema. Poor closure, the following complications occur: eye pressure, resulting in optic nerve hypoxia, vision loss; eyeball exposure, corneal dryness, conjunctival hyperemia and then lead to exposure keratitis; chemical burns in the eye, etc., photophobia, tearing, foreign bodies Clinical symptoms such as sensation and localized pain. According to relevant clinical literature reports, its incidence rate is as ...
