Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drape used in ophthalmic surgery.

[Conventional technology]

Drapes for ophthalmic surgery have conventionally had a structure in which a hole for exposing the affected area is provided in a sheet-like member (linen, nonwoven fabric, etc.) that covers the face.

During surgery, the drape gets wet due to outflow of blood or overflow of cleaning fluid, and the conventional solutions to this problem are as follows: a. The drape is made of a water-absorbing material (e.g., cotton cloth) so that the liquid can soak into it. or (b) the drape was made of a water-repellent material (for example, a synthetic resin non-woven fabric) to allow the liquid to flow down to the bottom of the operating table.

[The problem that the idea aims to solve]

However, if there is a large amount of bleeding or cleaning fluid, the above-mentioned item (a) (soaking) may not be sufficient to deal with the problem, and it is likely to become unclean.

In addition, according to item b (flow), patients must be placed in containers to prevent the floor of the operating room from getting dirty and slippery, which not only restricts the actions of doctors and nurses but also causes mental stress. It comes with the problem of being constrained. There is also the risk of accidentally overturning the container.

It is easy to think of attaching a bag to the drape to catch the liquid (blood, cleaning solution) flowing out from the affected area, but in order to embody this idea into a practical configuration, the following steps are required. Such technical problems must be resolved.

(i) By simply attaching a bag, it is not possible to expect that all the fluid flowing from the affected area will flow into the bag. That is, the bag entrance must be kept open.

(ii) Furthermore, since the member supporting the opening of the bag entrance must not interfere with the treatment, it must be possible to open the entrance in any shape depending on the situation.

(iii) Control systems are often used in ophthalmic surgery. Therefore, it is desirable that the bag provided on the drape should at least not interfere with the installation of the control system, and preferably facilitate the installation of the control system.

The purpose of this invention is to provide an ophthalmic bag with a water-receiving bag that can receive liquid flowing from the affected area without spilling it, does not have the risk of interfering with the treatment, and is convenient for installing the control system. The purpose is to provide a surgical drape.

[Means to solve the problem]

In order to achieve the above object, the drape of the present invention is an ophthalmological drape in which an affected area exposure hole is provided in a sheet-like member having a shape and size sufficient to cover the face, and an adhesive layer is formed on one side of the area around the affected area exposure hole. In a surgical drape, a water-receiving bag is made of a flexible, water-impermeable sheet-like material, and the water-receiving bag is positioned on the opposite side of the surface on which the adhesive layer is provided, so that the entrance edge of the water-receiving bag is exposed to the affected area. The water-receiving bag is attached along the edge of the hole, and a plastically deformable rod-like or band-like member is attached along the edge of the water-receiving bag, and the water-receiving bag is attached to the affected area exposure hole. The shape has a concave edge corresponding to a part of the periphery.

[Effect]

When the adhesive layer provided on one side of the drape with a water-receiving bag configured as described above is pasted around the eyes, the water-receiving bag appears on the outside of the drape, and its entrance opens into the affected area exposure hole. In this state, the inlet of the water-receiving bag can be shaped into a desired shape by appropriately bending a plastically deformable rod-shaped or band-shaped member (for example, a ribbon made of aluminum or extremely mild steel thin plate) by hand.

When a water-receiving bag is provided in a general-purpose covering cloth, the flow direction of the fluid to be contained in the water-receiving bag is undefined, but in ophthalmic surgery, fluid that overflows from the affected eye always flows toward the cheek or temple. If the water-receiving bag has a concave edge facing a part of the affected area exposure hole as in the above-mentioned configuration, a rational structure with no waste can be obtained.

〔Example〕

Figure 1 shows one of the ophthalmological surgical drapes according to the present invention.
It is a perspective view showing an example.

Before explaining the configuration of this embodiment, the process of testing, prototyping, experimentation, and improvement that led to the creation of the invention will be briefly described with reference to FIGS. 2 to 5.

FIG. 2 is a perspective view of a patient's face covered with an ophthalmic surgical drape of an unknown test created by the inventor of the present invention.

Reference numeral 1 denotes the main body of the drape, which is made of non-woven fabric approximately 1 meter square, and this figure shows its periphery cut away. 2 is the affected area exposure hole provided near the center, and the adhesive layer (third
(described below with reference to figures) is provided to be attached around the eyes.

In this draft, an annular water-receiving bag 3 was constructed from a vinyl sheet and attached around the affected area exposure hole 2. When implementing this proposal, the water-receiving bag described above may be made of any water-impermeable material such as non-woven fabric or synthetic resin film. FIG. 3 is a partially cutaway perspective view of the water-receiving bag described above. Reference numeral 3a denotes a drain nipple provided at the bottom of the bag, into which a drain hose 4 is fitted. In this draft, the term "annular" refers to endless shapes such as squares, ellipses, and circles.

FIG. 4 is a sectional view of the vicinity of the affected area exposure hole.

Back side around affected area exposure hole 2 (lower side in the figure)
A double-sided adhesive tape 5 is adhered to the adhesive layer to form an adhesive layer. 5a is release paper.

The annular water-receiving bag 3 shown in FIG. 3 is adhered around the affected area exposure hole 2, and the entrance of the bag is directed toward the affected area exposure hole 2.

A ribbon 6 made of a plastically deformable material (for example aluminum) is attached to the inlet edge of the water bag 3. Specifically, two opposing circular inner edges 3b,
3c (see FIG. 3) is adhered to the drape body 1 (surrounding the affected area exposure hole 2), and the ribbon 6 is attached along the other edge (3b or 3c).

The tentative ophthalmic surgical drape (Fig. 4) constructed in this manner is attached to the patient as shown in Fig. 2, and the entrance of the water-receiving bag 3 is opened by bending the aluminum ribbon 6 appropriately with your fingertips. keep it open.

FIG. 5 shows a different proposal from the above. The differences from the draft shown in Figure 4 are as follows.

Instead of configuring the annular water receiving bag 3 as shown in FIG. 3, a ring-shaped piece 3' is formed by cutting out a vinyl sheet in an annular shape, and its outer periphery 3d is attached to the drape body 1.
to form a water-receiving bag.

The draft plan shown in FIG. 5 has a simpler structure than the draft plan shown in FIG. However, in the draft plan shown in FIG. 5, the drape body 1 must be made of a water-impermeable material in principle, and at least the vicinity of the affected area exposure hole 2 must be waterproofed.

In the draft shown in FIG. 4, the drape body 1 does not necessarily have to be made of a waterproof material, so there is a wide range of selection of materials that are comfortable to the touch.

3c shown with spots in FIG. 2 is the entrance opening of the water receiving bag 3. When the treatment is performed in this way, all the liquid that overflows from the eyes will flow into this opening 3e,
Does not spill outside. Moreover, since the three-dimensional shape of the opening 3e can be made into any shape by freely bending the ribbon, it is sufficient to make it into a shape that does not interfere with the treatment.

As a result of continuing practical testing and research on the above-mentioned ophthalmological surgical drape, we confirmed that it has sufficient practical value in terms of functionality, and that there is still room for improvement economically. The annular water-receiving bag in the draft plan of FIG. 2 is made into a half-split shape, and as shown in FIG. A half-circular or horseshoe-shaped water receiving bag 8 having an inlet edge 8a is constructed.

Fluid spilled from a patient's eye during eye surgery;
(Blood, washing fluid, tears, etc.) always flows down toward the patient's cheeks or temples, but never up toward the bridge of the nose. The semicircular water receiving bag 8 in the illustrated embodiment is sufficient. According to the structure of this embodiment, the structure is simpler and the manufacturing cost is lower than that of the prototype shown in FIG.

This embodiment (Fig. 1) is a further improvement of the prototype shown in Fig. 2, and although it does not appear in Fig. 1, it is equipped with the plastically deformable aluminum ribbon shown in Fig. 4. Therefore, the inlet of the water receiving bag 8 can be opened in an appropriate shape so as not to interfere with the treatment.

Note that in view of the fact that the amount of fluid that overflows from the eye during ophthalmic surgery is relatively small, the drain hose 4 (see FIG. 2) and the hose attachment nipple 3a are omitted in the embodiment shown in FIG. .

[Effect of idea]

According to the eye surgery drape of the present invention, the liquid flowing out from the affected area can be received in the water receiving bag without spilling, and the inlet of the water receiving bag can be opened and held in any shape. This has an excellent practical effect in that it does not interfere with the treatment and does not interfere with the installation of the control system.
