Description

Leakage-proof film for ophthalmic surgery

Technical Field

The application relates to the technical field of ophthalmic surgery, in particular to an ophthalmic surgery leakage-proof film.

Background

The eye operation, especially the inner eye operation, needs the intraocular perfusate and the external flushing to finish the operation, at present, the clinic mainly adopts the transparent film with the water storage bag on the side, the inner surface of the transparent film is adhered with the viscosity, the transparent film is adhered on the eyelid and the skin surface around the eye socket, the water can not flow under the film when flowing under the film, and the water storage bag on the side flows over the film, thus achieving the purpose of preventing the overflow everywhere in the operation.

However, in actual intraocular surgery, the existing water storage bag type transparent adhesive film has the following defects:

(1) Before the hole towel is laid in the ophthalmic operation, the eyelid and surrounding skin are disinfected by the iodophor, the adhesion degree of the adhesive film and the skin is reduced when the operation adhesive film is pasted, even if the iodophor is wiped dry and then pasted, the effect is poor, especially the inner canthus and the outer canthus are easy to leak water, even if the effect of the adhesive film is good, the adhesive film can be separated from the skin under the condition of repeated flushing.

(2) When the film is not adhered, overflowed water flows under the film, and is dripped on an operator along the face of a patient through an outer canthus or an inner canthus, if the patient is an infectious disease patient, the infectious disease exposure risk of a doctor is increased, or water rushed out from the operation eye flows up and down the film and between the left eye and the right eye, the infection risk is increased, and cough is conducted upwards, so that the infection risk of the operation eye is increased.

(3) When in vitreoretinal surgery, the patient's breath will move up along the slit at the inner canthus, causing the wide-angle lens to fog, blurring the surgical field, and affecting the surgery.

In short, the effect of the ophthalmic surgical patch can directly affect the aspects of the operation and the post-operation.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and/or" as it appears throughout includes three parallel schemes, for example "A and/or B", including the A scheme, or the B scheme, or the scheme where A and B are satisfied simultaneously. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present application.

Referring to fig. 1, an embodiment of the present application provides an ophthalmic surgical leakage-proof patch, which includes an upper patch and a lower patch. The upper layer film is a conventional water storage bag type transparent film, the lower layer film is attached to the eyelid and the surrounding skin during specific use, the upper layer film is attached to the surface of the lower layer film, and when the intraocular perfusate and external flushing are carried out, water and liquid flow into the water storage bag along the surface of the upper layer film, and flushing liquid can be prevented from leaking into the surface of the surrounding skin of the eye to a great extent by virtue of the double-layer film structure.

In the above, the lower film is a rectangular structure with the length of 12cm and the width of 8cm, the lower film is centrally provided with a rectangular hole 4 with the length of 4.5cm and the width of 3.5cm, the design of the rectangular hole 4 separates the bony orbit from the movable eyelid, and particularly, the design of the rectangular hole 4 is consistent with that of the bony orbit, so that the degumming and water leakage of inner and outer canthus parts are limited. In addition, the rectangular hole 4 is internally provided with an eyelid pulling piece 5 for pulling the upper eyelid and the lower eyelid towards two sides, the eyelid pulling piece 5 is in a convex structure and can be pulled upwards and downwards respectively to be stuck on the upper side and the lower side to open the eyelids. Of course, the lower film is a disposable film, the film is sterile, ethylene oxide is adopted for sterilization, and the residual amount of the ethylene oxide is not more than 10ug/cm < 2 >.

Meanwhile, in this embodiment, the lower film includes a protective layer and an adhesive layer, and the protective layer is adhered to both sides of the adhesive layer. The protective layer is release paper, namely front release paper 2 and back release paper 3, and is made of silicon-coated paper. The adhesive layer is PU film 1 (polyurethane film) with pressure-sensitive adhesive coated on the surface, and compared with the upper layer adhesive film made of polyethylene film material, the polyurethane film is more skin-friendly and soft and has better comfort. When in use, the protective layer on one side is torn off, the adhesive layer is adhered to the skin around the eyelid, and then the protective layer on the other side is torn off and adhered to the upper layer adhesive film. Of course, in a preferred embodiment, the length and width of the protective layer are greater than those of the adhesive layer, so designed that the finger does not contact the adhesive layer when tearing off the two protective layers, avoiding sticking to the hand.

Further, the protective layer is provided with the perforation line 6, and the perforation line 6 is located to be provided with and carries pull tab 7, and the benefit of this design lies in can conveniently light tearing off the protective layer.

In summary, the anti-leakage adhesive film for ophthalmic surgery provided by the embodiment of the application comprises the following specific application methods:

After the conventional iodophor disinfects the eye and facial skin three times, the aseptic towel is used for wiping the skin of the eye and surrounding iodophors with aseptic gauze, one surface of the lower layer of adhesive film is torn off from the release paper, the rectangular hole 4 is aligned to the eye patch to enable the eye patch to be in full contact with the skin, the other surface of the lower layer of adhesive film is torn off from the release paper, the eyelid pull tab 5 is pulled away to two sides after being attached to the upper eyelid and the lower eyelid, and finally the water storage bag type transparent adhesive film is attached to the lower layer of adhesive film. Therefore, the double-layer waterproof structure of the upper-layer film and the lower-layer film ensures that the situation that the film leaks water and the wide-angle lens is fogged is difficult to occur in the long-time operation process by flushing and soaking, meanwhile, under the condition that the film is not well adhered in time, the liquid can be greatly limited to leak into the lower-layer film by virtue of the double-layer waterproof structure, and the design of the eyelid pull tab 5 can pull the upper eyelid and the lower eyelid towards two sides during operation, so that the edge of the upper-layer film is beneficial to wrapping the eyelid margin eyelashes, and the effect of eyelashes on operation is avoided while the infection risk is reduced.

The foregoing description of the preferred embodiments of the application is not intended to limit the application to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the application are intended to be included within the scope of the application.
