A preferred example of the drape unit according to the present invention will be described in detail. As shown in FIGS. 1 and 2, both the first sheet and the second sheet are formed of a sheet material having a substantially rectangular plane portion. The 1st sheet | seat 1 has the 1st notch part 11 cut off toward the center from the one side of the outer peripheral edge part which is one side of a square. A plurality of members 101 and 102 are installed in the periphery of the notch portion 11 by changing the position of the fixing member. Fixtures 101, 101 and 102, 102 each form a fixing member. A fixing member for fixing both the sheets together with the fixing member 23 of the second sheet 2 is selected from the plurality of fixing members, and is fixed by the fixing member. In this way, both units jointly form a perforated drape. Depending on which of the fixing members 101 and 102 is selected, the size of the opening 4 formed by both drapes can be changed. Further, the shape and size of the opening 4 formed by the shape of the first sheet, in particular, the shape of the cut portion 11, the width of the cut, the depth, and the like can be changed.
The first sheet does not have to be singular, and the notch 11 having any shape can be formed by combining a plurality of sheets.

[Second sheet]
The 2nd sheet | seat 2 may have the cut | notch part 21 formed so that one side of the outer peripheral edge part might be dented toward the center. Moreover, it is good also as a square shape, without forming a notch part.
In the second sheet 2, for example, as shown in FIG. 2, the fixing member 23 is substantially on the center line. This fixing member corresponds to the fixing members 101 and 102 installed on the first sheet, and the drape is completed by connecting the first sheet and the second sheet with the fixing member. The fixing member may be of any mechanism as long as both can be firmly fixed. For example, a fixing member is installed on the fixing member, and both units are coupled by the fixing member. The fixing tool can be preferably a dot button. The dot button is composed of a convex type and a concave type for receiving it, and it is arbitrary which one is provided on the first sheet or the second sheet. In the drawing, convex dot buttons are represented by black circles, and concave dot buttons are represented by white circles. The specific structure of the fixing member 23 provided on the second sheet 2 is made of a flexible strip-like or string-like material 31 having an intermediate portion coupled to the second sheet 2, and at both ends thereof Fixing tools 301 corresponding to the fixing tools 101 and 102 installed on the first sheet 1 are installed.
In the fixing members 101 and 102 of the first sheet 1, the fixing member is preferably installed across the notch portion 11, for example, the convex shape of the pair of dot buttons 101 and 101 across the notch portion 11. Is installed. The concave shape of the dot button 301 which is a fixing tool installed on the second sheet 2 is stopped by the convex shape of the dot button, and both units are fixed. It is preferable that the distance between the fixing members 301 of the second sheet 2 is a little longer than that between the fixing members 101, 101 of the first sheet, so as to correspond to ease of attachment and flexibility after attachment. .
The second sheet does not have to be singular, and an opening 4 having an arbitrary shape can be formed by combining a plurality of the second sheets and in cooperation with the notch 11 of the first sheet.

[Second sheet fixing member and cord holder]
Since a plurality of fixing members 101, 102 of the first sheet 1 are provided at a predetermined interval, the size of the surgical opening 4 can be adjusted depending on which of the fixing members 101, 102 is selected. it can. Although it does not specifically limit as the fixing member 23 of the 2nd sheet | seat 2, The cord holder 23 provided in the 2nd sheet | seat 2 can be used.
The second sheet 2 is provided with a cord holder having a flexible string shape or belt shape, and this can be used for bonding between the sheets. This cord holder has a central portion fixed to the drape body and a fixing tool 301 installed at both ends. And, by wrapping the cord holder with a cord of an electric product such as an electric scalpel used in an operation and stopping it, the long cord is fixed to the drape body so as not to interfere with the operation. However, in the present invention, this cord holder is also used for coupling between units. Originally, the end portion of the cord holder can be fixed to the surface of the second sheet 2. For example, a fixing tool 301 is installed on the cord holder 23, and a corresponding fixing tool 302 is installed on the surface of the second sheet. The cords are held in a space formed by combining the fixing tool 301 and the fixing tool 302. Have been to.

A concave dot button 301 as a coupling tool is installed near both ends of the band 31, and a convex dot button 302 is installed near the end of the band 32. The concave dot buttons 301 and 301 of the band 31 are stopped by the convex dot buttons 101 and 101 which are fixing members of the fixing member disposed on the first sheet 1. At this time, the fixing member also functions as a fixing member for both sheets. Further, by fixing the uneven dot buttons 301 and 202 together, the cords can be sandwiched and fixed between the band 31 and the band 32.

[Drape formation]
In order to superimpose and bond the two sheets and use them as a drape, first, the shape and size of the opening to be formed are determined so as to meet the surgical purpose, for example, according to the shape and size of the surgical field. Next, the two units are arranged so that both sheets overlap each other with both notches facing each other so that an opening having a predetermined shape and size can be formed. At this time, the fixing member 101 or 102 of the first unit and the fixing member 23 of the second sheet are arranged in a contactable position, and are coupled by both the fixing members. Since the fixture 301 arranged on the second sheet is provided in the vicinity of the end of the flexible belt-like object, the positional relationship can be adjusted during or after the units are combined.

  The dimension of the notch is not particularly limited. For example, if it is used as a medical drape, it may be in accordance with the opening required for surgery. Examples of the shape of the notch include a polygon such as a triangle, a quadrangle, a pentagon, and a hexagon, a circle, a semicircle, and an ellipse.

[Sheet material]
The sheet material is preferably made of a water-repellent processed plastic film, cloth (woven cloth, etc.), paper, etc., and is preferably highly flexible. In order to keep the surgical field clean, a sterilized one is preferably used. Examples of the polymer used as a material for plastic and fabric fibers include polyester, polyolefin, polyurethane, acrylic polymer, and fluorine polymer.
The material used for the water repellent processing is, for example, a fluorine-containing compound or a silicone-containing compound. The sterilization method depends on the material of the sheet material, but heat sterilization, ultraviolet sterilization, EO gas sterilization, and a method of applying or impregnating an antibacterial agent are used.

As a sheet material suitable for use in the present invention, for example, a base fabric using a material that can withstand washing and sterilization at a high temperature such as polyester, cotton, polyamide, polyacrylonitrile, polypropylene, polyurethane, and fluororesin is used. It is desirable to use a base fabric that is free from pinholes, but water-repellent finishes and resins can be used even for base fabrics having water absorption properties such as cotton or base fabrics having pinholes. It is possible to obtain an optimal sheet material by coating and laminating processes. By configuring the sheet material with a material that can be used repeatedly after washing, it is possible to reduce medical waste. Since blood or the like adheres to the base fabric after use, it is reused after being sterilized (for example, a 10-minute hot water disinfection process using hot water at 80 ° C.) so as not to become an infection source. . The sheet material is preferably sewn so that the surface thereof has a barrier property against bacteria and viruses, for example, so that a sewing hole is not exposed at a sewing location.
More preferably, the risk of infection can be reduced by providing a sheet or fabric having a bacterial barrier property due to water repellency and waterproof performance around the opening. As a material having such characteristics, for example, it is made of a fabric that has a very high moisture permeability without using a coating agent, provides a comfortable wearing feeling, and greatly suppresses the occurrence of lint, and has an external barrier property. A material that retains the air and ensures air permeability on the wear side (for example, a polyester microfiber material or a multilayer structure material that meets US / ANSI / AAMIPB70 barrier performance classification levels 2 to 3), and a coating on the fabric surface forming a multilayer structure material which does not allow even penetration of any liquid or microorganisms because it increased to nearly the limit of waterproof and durable by filling a coating material to the gaps of the fibers at the same time (e.g., the American National standards Material that meets the barrier performance classification level 4 of ANSI / AAMIPB70).

  Since the peripheral portions of the cutout portions 11 and 21 serving as the openings of both units are easily contaminated by a patient's body fluid or the like, it is preferable to provide the above-described materials particularly in order to require a bacterial barrier property. . Furthermore, a material for reinforcement can be attached to the notch, and characteristics such as liquid absorption can be adjusted. The reinforcing sheets 12 and 22 are provided so that the positions of the notches 11 and 12 or the opening 4 are aligned, and the edge of the opening is reinforced. For example, the surface is composed of water-absorbing material, and the back side is provided with a sheet composed of water-resistant material on the surface of the base fabric to prevent the liquid from adhering to the patient. It is possible to reliably prevent the infection to the surgeon. In this invention, the reinforcement parts 12 and 21 part provided in the peripheral part of the notch part 11 of the 1st sheet | seat or the 2nd notch part 21 correspond. By providing this sheet and directing the waterproof surface of the reinforcing sheet to the patient side, the patient's body fluid can be prevented from penetrating into the base fabric. Reinforcing property can also be imparted by a bacterial barrier sheet. The reinforcing sheet 12 of the first sheet 1 can be formed to have a double reinforcing sheet by allowing the end of the reinforcing sheet 12 to be folded back and being fixed by the fixtures 121 and 121.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a drape unit that can easily make a drape having an operative field opening that matches a surgical purpose on the spot and a medical drape formed therefrom. For example, applicable to draping for neurosurgery (including U-shaped), shoulder arthroscopic half-sitting, ophthalmic, gynecological, traction / CHS, percutaneous renal stone crushing, orthopedic surgery, etc. Especially, it is suitable for an application for performing an operation with various devices attached to the affected area. The present invention shortens the draping time, eliminates the need to prepare cloth forceps, and fixes the drape cord holder and U drape with dot buttons, eliminating the risk of the drape coming off during the operation and maintaining cleanliness. I was able to perform surgery.
In addition, since the joint surface can be easily opened, it is possible to enlarge the opening during the operation, which makes it easier to clean up after the operation, washing in the reuse process, folding, and inspection, as compared to a conventional disposable drape. The cost of drape required for surgery can be kept low.
