Description

A partially visible hydrogel eye patch

technical field

The invention belongs to the field of medical devices, and in particular relates to a partially visible hydrogel eye protection patch.

Background technique

During the operation of general anesthesia patients, head surgery patients, prone position surgery patients, and 1-5-year-old infant surgery patients, the application of anesthetics, the placement of body positions, and the stimulation of disinfectant can all cause eye damage. Produce conjunctivitis, keratitis, and even corneal ulcers.

At present, a number of research institutions have developed hydrogel eye patches to protect the eyes. Polymer hydrogels provide a moist microenvironment for the eyes and prevent exposure eye damage. However, there are still some deficiencies in clinical application.

For example, the patent application number is 201120055618.X "a self-adhesive moisturizing eye patch" utility model patent, the eye patch described in this patent can only cover the eyeball and is fixed by the medical pressure-sensitive adhesive on both sides. fall off. However, due to poor adherence and airtightness of the gel, gaps are formed when it is separated from the eye skin. When the surgical disinfection area is close to the eyes, the disinfectant enters the eyes through the gaps, irritating the eyes, and increasing the incidence of eye complications and even infection. .

Another example is the patent application number 201220703877.3 "A Hydrogel Eye Protective Dressing with Fully Enclosed Structure" and the utility model patent and patent application number 201220703878.8 "A self-adhesive long-lasting moisturizing eye protection with a four-layer sandwich structure. The eye protection patch described in the "Applying" utility model patent is a fully enclosed structure, which can provide a safer airtight and moisturizing environment for the eyes of patients with general anesthesia and deep coma. However, when the operation takes a long time or blood vessels are damaged during the operation, massive bleeding will occur. When the patient has a large amount of bleeding, when the general anesthesia is too deep or the implementation of controlled hypotension, and the blood pressure cannot be lowered during the operation, retinal hemorrhage is prone to occur. Since the eye patches described in the above patent completely cover the eyes and are invisible, doctors cannot judge eye bleeding in time and cannot take targeted measures, resulting in aggravated injuries.

Contents of the invention

Purpose of the invention: In order to enable doctors to observe eye bleeding in time during the operation, the present invention provides a partially visible hydrogel eye protection patch, which can provide a closed moisturizing environment for the eyes of surgical patients, and can be used at any time Observe the damage of the eye so that timely treatment measures can be taken.

Technical solution: In order to achieve the above technical purpose, the present invention proposes a partially visible hydrogel eye protection patch, which includes a release film, a hydrogel layer, a non-woven fabric layer, a release paper handle, an adhesive layer and a support pallet. Wherein the hydrogel layer is a translucent hydrogel, the non-woven fabric layer is the intermediate bridging layer between the hydrogel layer and the adhesive layer, and the two ends of the adhesive layer of the adhesive layer are designed with release paper handles, the The supporting layer is bonded to the hydrogel in the visible area, and is in contact with the non-adhesive surface of the adhesive layer, supporting the shape of the entire product.

Specifically, the hydrogel layer is pasted on the non-woven fabric layer, and then combined with the pasting layer through the non-woven fabric layer, and the non-woven fabric layer and the pasting layer are on the corresponding two sides. The position of the pupil of the eye is hollowed out, and the edges of the two layers of hollows are aligned. The area of the hollowed out should be enough to expose the eyes and not larger than the surface area of the hydrogel layer. Utilizing the highly transparent property of the hydrogel layer itself, a visible window is formed.

The beneficial effect of the utility model is: through the visible window, it is convenient for the doctor to observe the changes of the patient's eyes at any time during the operation, and at the same time, a good fully enclosed slightly humid environment can be provided for the eyes.

On the basis of the above technical solutions, the utility model can also be improved as follows.

Further, the upper surface of the nonwoven fabric layer is bonded to the lower surface of the hydrogel layer, and the lateral ends of the nonwoven fabric are extended along the arc of the outer ring edge of the nonwoven fabric to form a handle with a length of 1 to 30 mm.

The beneficial effect of adopting the above further solution is that: the hydrogel layer is first compounded and pasted with the non-woven fabric layer, and then connected with the pasting layer through the non-woven fabric layer, which can increase the stability of the connection. The handles at both ends of the nonwoven fabric are convenient for production and operation, and can increase the connecting area between the nonwoven fabric and the adhesive layer, thereby increasing the stability of the connection.

Further, the shape of the adhesive layer conforms to ergonomics, the vertical lower edge of the adhesive layer is 5-20 mm larger than the lower edge of the hydrogel layer, and the vertical upper edge is 0-5 mm larger than the upper edge of the hydrogel.

The beneficial effect of adopting the above further solution is: the shape of the adhesive layer conforms to human engineering, and the surface area of the adhesive layer is larger than the surface area of the non-woven fabric layer and the hydrogel layer. The local visible medical hydrogel eye patch can be closely attached to the face to form a closed and moist microenvironment. The vertical lower edge of the adhesive layer is 5-20 mm larger than the lower edge of the hydrogel layer, so that the adhesive layer and the skin can be tightly bonded to prevent the infiltration of disinfectant. The vertical upper edge of the adhesive layer is 0~5mm larger than the upper edge of the hydrogel, which can prevent the adhesive layer from sticking to the eyebrows when the local visible medical hydrogel eye patch is removed from the face.

Further, the two ends of the adhesive surface of the adhesive layer are bonded to the attached release paper handles.

The beneficial effect of adopting the above further solution is: avoiding the contact between the user and the adhesive surface of the adhesive layer, and facilitating the operation.

Further, the lower surface of the release film layer is attached to the upper surface of the hydrogel layer, the upper surface of the nonwoven fabric layer is bonded to the lower surface of the hydrogel layer, and the inner circumference of the upper surface of the adhesive layer is bonded to the lower surface of the nonwoven fabric layer. The surface is bonded, and the surface area of the release film is greater than the surface area of the adhesive layer.

The beneficial effect of taking the above-mentioned further scheme is: the release film layer is connected with the non-woven fabric layer and the adhesive layer through the hydrogel layer, so as to protect the hydrogel layer, the non-woven fabric layer and the adhesive layer from contamination, and also prevent Paste adheres to the outer packaging.

Further, the upper surface of the support layer is bonded to the lower surface of the adhesive layer, the surface area of the support layer is the same as that of the release film layer, and any one of PET, PVC, and PP is used, with a thickness of 0.1-2mm, and has a support ability.

The beneficial effect of adopting the above further scheme is that it is convenient for the operator to take out the partially visible medical hydrogel eye protection patch from the package, and the eye protection patch will not be deformed during transportation.

Preferably, the partially visible medical hydrogel eye protection patch is packaged in an aluminum foil bag after molding, and is provided as a sterile product. The packaged partially visible medical hydrogel eye protection patch needs to be sterilized to ensure Product Safety.

The size of the partially visible medical hydrogel eye protection patch of the utility model can be adjusted according to actual needs.
