Hole towel for ophthalmologic operation

Abstract

The hole towel comprises a sterile hole towel body, the surface of the hole towel body is made of sterile hydrophobic spun-bonded non-woven fabric, eye openings are formed in the hole towel body, medical pressure-sensitive adhesive is arranged behind the eye openings, in addition, L-shaped water blocking grooves are further formed in the periphery of the hole towel body, and the water blocking grooves are communicated with the hole towel body. The water blocking grooves are made of PVC materials, liquid collecting holes are formed in the lower left portion and the lower right portion of the hole towel body, and at least one gravity block is arranged on each edge of the periphery of the hole towel. By the adoption of the L-shaped water blocking groove and the gravity block, the situation that a liquid collecting bag needs to be replaced in the midway in the prior art can be avoided, the drape can be prevented from moving, and the fit performance of the drape and the face can be improved.

Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a drape used for ophthalmic surgery. Background Art

[0002] Surgical drapes are one of the necessary surgical items for ophthalmic surgery. They are usually disposable. During ophthalmic surgery, the patient usually lies in a supine position with a sterile drape placed on the face to expose the eyes and isolate other parts to avoid contamination and facilitate the normal progress of the operation.

[0003] On the one hand, the existing surgical drapes have poor fit with the face, which easily creates large gaps, causing the flushing liquid to accumulate around the eyes and cannot be quickly discharged from the surface of the drape. In addition, existing ophthalmic surgeries often require a large amount of flushing liquid. The collection liquid bags used in the existing technology are often small in size. On the one hand, they need to be replaced frequently during the operation. On the other hand, since the collection liquid bags are placed on the surface of the drape, the operation of the operation is affected. Utility Model Content

[0004] The utility model aims to provide a special drape for ophthalmic surgery to solve the problems in the current background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A drape for ophthalmic surgery comprises a sterile drape body, the surface of the drape body is made of sterile hydrophobic spunbond non-woven fabric, the drape body is provided with eye openings, and medical pressure-sensitive adhesive is provided behind the eye openings. In addition, L-shaped water retaining grooves are provided around the drape body, and the water retaining grooves are made of PVC material. Liquid collection holes are provided at the lower left and lower right of the drape body, and at least one gravity block is provided on each edge around the drape.

[0007] Furthermore, a spun electrostatic layer is also provided on the surface of the towel body.

[0008] Furthermore, the liquid collecting hole is provided with a hole sleeve made of silica gel, and a catheter is connected to the hole sleeve.

[0009] After adopting the above technical solution, the utility model has the following beneficial effects:

[0010] When using, first tear off the release paper on the medical pressure-sensitive adhesive so that the eye opening is well fixed around the eyes to prevent liquid from flowing into other parts of the face.

[0011] During the operation, since the gravity blocks are used around the drape, on the one hand, since the gravity blocks are located below the water retaining grooves, when the patient is lying, the plane of the surgical part of the eye is higher than the water retaining grooves around it, so the excess liquid mainly flows downward into the water retaining grooves on the left and right sides due to the effect of gravity. In addition, the use of the gravity blocks helps to improve the fit with the face, thereby better promoting the timely discharge of the flushing liquid from the surface of the drape. A small amount of liquid will flow below or above, but because the water retaining grooves around are connected, all the liquid in the water retaining grooves will eventually be collected in the liquid collection holes at the lower left and lower right, and finally discharged through the catheter below the liquid collection hole. Further, it can be collected into a large container through the catheter, thereby avoiding the situation in the prior art where the liquid collection bag needs to be replaced midway.

DETAILED DESCRIPTION

[0015] The present invention is described and explained below in conjunction with specific embodiments.

[0016] In order to further explain the technical solution of the present utility model, specific embodiments are described below with reference to the accompanying drawings.

[0017] Example 1

[0018] See attached Figure 1 The utility model provides a drape for ophthalmic surgery, comprising a sterile drape body 1, the surface of the drape body is made of sterile hydrophobic spunbond non-woven fabric, an eye opening 3 is arranged on the drape body, and medical pressure-sensitive adhesive is arranged behind the eye opening. In addition, an L-shaped water retaining groove 2 is arranged around the drape body, and the water retaining groove is made of PVC material with certain mechanical strength. A liquid collecting hole 6 is arranged at the lower left of the drape body, and a symmetrical liquid collecting hole is arranged at the lower right. At least one gravity block is arranged on each side around the drape. Since the gravity block is located below the water retaining groove, the plane of the eye surgical site is higher than the surrounding water retaining grooves, which helps the liquid to flow downward into the surrounding water retaining grooves. Since the surrounding water retaining grooves are connected, this helps the liquid to flow out from the lower left and lower right liquid collecting holes.

[0019] See Appendix for further information. Figure 2 , attached Figure 2This is a schematic diagram of the water retaining trough in the utility model. The water retaining trough is made of PVC material with a certain strength, which can ensure that when the liquid flows downward into the surrounding water retaining troughs, it will not overflow.

[0020] The product form of the utility model is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the utility model.
