2. Description of the Related Art Surgical cloth is a sheet used for providing a barrier between an incision and a non-disinfected area in a surgical operation, and is waterproof or water repellent according to the conditions of use. Or, it may be provided with an adhesive layer for sticking to the body of a patient, but it is originally a rectangular linen or non-woven sheet. However, with the progress of medicine, the modes of surgery have diversified, and the medical instruments used during surgery have become complicated and large, so that various problems have occurred with a simple rectangular sheet. In order to eliminate such inconveniences, various surgical covering cloths having a portion (also referred to as sleeves) covering a patient's arm, surgical covering cloths having a gusset, and the like have been proposed and are known.
In this "Prior Art" section, it is necessary to understand the "problems to be solved by the invention" described below.
(A) A T-shaped cover cloth having a main body part that covers the patient's torso and lower limbs, and a sleeve part that covers the patient's arm, and (b)
The known prior art closest to the present invention will now be described with respect to a gusseted cover structure which is stretched like a curtain by an anesthesiologist's arch or stand. For convenience of explanation, it is assumed that the patient is laid on a rectangular bed-shaped operating table, and the covering cloth is used by covering the patient. Hereinafter, unless otherwise specified, the direction of the patient's head is referred to as the top,
The direction in which the legs are extended is called the downward direction.

Japanese Patent Publication No. 3-7372 entitled "Surgical drape and method of forming the same" is known as a covering having a sleeve portion for covering a patient's arm (hereinafter, abbreviated as known surgical drape). FIG. 3A shows one of the known surgical drapes.
It is a perspective view showing an example, and a patient is laid on an operating table 9A. The operating table 9A is horizontally supported by a pedestal 10A, and an arm boat 11A on which a patient's arm is placed extends to the side of the operating table 9A, and the patient lies on his back with his arms spread laterally. In this known surgical drape, the drape body 10 covers the patient's torso and lower limbs.
And a drape lateral arm portion (referred to as a T-shaped portion in the above publication) that covers the patient's arm and a portion above it 15
And are joined in a T shape. The reason why this type of drape is formed in a T shape will be described with reference to FIG. 3B. When the width dimension of the rectangular operating table 9A is Wb, the width dimension W of the drape body 10 is larger than the dimension Wb. The size is appropriately set large, and the side edge 13 is designed so that the part that covers the patient and the operating table 9A hangs down toward the floor. However, if the width W is excessively large, the floor surface is not touched, which is not preferable, and thus the width W cannot be increased without limit. On the other hand, 1
Since the dimension l between both ends of the pair of arm boats 11A must be appropriately larger than the length when the patient spreads both arms, l> W is inevitable, and as a result, the entire drape has a T shape. Like When the above T-shaped drape is industrially produced, there is a problem as shown in FIG. That is, as shown in FIG. 1A, a sheet material having a width dimension larger than the dimension l is used to cut off 1a and 1b indicated by hatched lines, and
If c is cut out to form the T-shaped drape 1, the yield of the material is poor and it is uneconomical. In order to solve the above-mentioned problems relating to the material economy, there is known a technique of arranging two rectangular sheets 2a and 2b as shown in FIG. 4 (B) and joining overlapping portions indicated by spots. is there. However, when suture is used for this joining, a needle hole is formed and the function as a bacterial barrier is deteriorated. Adhesive bonding or heat fusion is desirable in order to prevent the formation of needle holes, but the work of bonding or heat fusion in a relatively long section such as the width W shown in the drawing is considerably difficult. There is a problem of high cost.

The known surgical drape is basically one in which two rectangular drapes are joined vertically and horizontally as shown in FIG. 4B, and the number of manufacturing steps is reduced. The purpose of this is to reduce the amount of material and to make the material structured as follows. FIG. 5 is a top view showing an example of the known surgical drape, and as described in FIG. 3 above, the body portion 10 and the lateral arm portions (sleeve portions) 15 are arranged vertically and horizontally to form a T-shape. Is joined to. 16 is the upper edge on the head side of the patient, 12 is the bottom edge (lower edge) on the foot side,
Reference numeral 4 is a side edge of the body portion, and 18 and 19 are side edges of the lateral arm portion. Reference numeral 40 is an opening for surgery, and 43 is a reinforcing material.
Reference numeral 44 is a pad for an instrument having a non-slip surface for placing instruments. In the figure, 11 is an upper edge of the body portion 10, and 17 is a lower edge of the lateral arm portion 15. The upper edge 11 and the lower edge 17 are overlapped and joined. This joint is configured as follows. That is, FIG.
Is a plan view of a single product in which the lateral arm portion 15 is extracted and cut, as shown by a solid line. Among these cuts, the line in the left-right direction on the paper surface in FIG. 6 becomes the lower edge 17 of the lateral arm portion described in FIG. 5 above, and is joined and superposed on the upper edge 11 of the body portion through the following operation. To be done. The side arm portion 15 with the cut 17 shown in FIG.
Is folded back using the chain line 4 shown in the figure as a fold line. The folded state is shown in FIG. Further, the chain line 6 shown in the drawing is folded back to form a structure as shown in FIG. 7B, and the body portion 10 described above is overlapped and joined. Pieces b and b'folded back with the chain line 4 shown in FIG.
6 is returned to the state of FIG. 6 and the lateral arm portion 15 is expanded into a rectangle, the same as the upper half of the surgical drape shown in FIG. 5 (however, the opening 40 and the reinforcing member 43 are not provided yet). Become. Reference numeral 11 is an upper edge of the body portion 10, and reference numeral 17 is a lower edge of the lateral arm portion 15. The upper edge 11 and the lower edge 17 are overlapped with each other by an overlap dimension t and joined. As can be easily understood from the above-described configuration, the length of the joint portion in this case is the width dimension W of the drape body portion 10.
Is equal to

As an application example of the above-mentioned known surgical drape configured so that a patient covers his / her arms that are spread to the side, when not only allowing the patient to open both arms but also opening both arms, FIG. As shown, cuts 55 and 54 are made in parallel with the drape side edges 13 and 14 from the bottom edge (lower edge) 12 of the body portion 10,
A technique of folding back the chain line 56 as a fold line is also disclosed in this publication, but in this case as well, the upper edge 11 of the body portion 10 and the lower edge 17 of the lateral arm portion 15 are formed to form an arm covering portion (sleeve). Is required to be overlapped and joined, and the joining length is equal to the width W of the body portion 10.

The basic shape of the T-shaped drape shown in FIGS. 4A and 4B is the joining of two sheets even in the T-shaped drape 1 formed by cutting out as shown in FIG. Also in the T-shaped drape 2 configured as above, the developed shape is a plane figure. However, when these drapes are actually covered on the patient, they must have a three-dimensional shape as shown in FIG. 3 above. In the example of FIG. 3, the T-shaped drape having a simple plane figure is not sufficient to cover the arm boat 11A extending laterally from the operating table 9A without difficulty, so that the known surgical drape is A folded fold as shown in FIG. 7 is provided. As described above, as a technique for three-dimensionally stretching the drape, Japanese Patent Publication No. 57-58944, "surgical cover with improved arm cover" is known (hereinafter, abbreviated as known surgical cover). ).

FIG. 9 is a perspective view showing an example of the above-mentioned known surgical cover, and FIG. 10 is a plan view of the same. 9 shown in FIG.
A is an operating table, and 12A is a patient who is laid down on the operating table, with his arms spread laterally and placed on the arm board 11A and lying on his back. 10A is the base of the operating table 9A.
The basic structure of this known surgical cover is such that the body portion 14A and the lateral arm portion 15A are vertically and horizontally arranged and superposed and joined (sewn, glued, heat sealed, etc.). . 20A is a window division, and the flap 27A and the protection plate 2
1A and. 24A is an instrument pad, 2
5A is a knob for attaching the tube. Body part 14A
Both sides of the flap are hung on both sides of the operating table 9A
A and 18A are formed. The characteristic feature of this known surgical cover is that the lower edge of the lateral arm portion 15A is positioned so as to partially overlap with both sides of the body portion 14A.
The flap 18A of the armboard is joined. Figure 1
16A shown at 0 is a lateral arm portion 15A and a body portion 14A
And 19A is a joint between the lateral arm portion 15A and the armboard flap 18A.

As described above, the drape (also called the cover or the cover cloth) provided with the arm cover (sleeve) for covering the arm of the patient placed on the armboard has been devised, while the drape has been devised. Japanese Patent Application Laid-Open No. 64-25845 discloses a surgical drape and a method for producing the same (hereinafter, referred to as a known surgical drape) as a technique for three-dimensionally stretching the same. In the known example shown in FIGS. 3 and 9, the patient's head is covered with a drape, but this known surgical drape partially covers the patient's head as shown in FIG. It is designed to fold up vertically from above the neck or chest to the earth. Such an arrangement is intended to cover the arch or stand for anesthesia and forms a vertical shield wall that shields the anesthesiologist and his staff from the surgical site. 1B shown in FIG. 11 is a first rectangular portion covering the patient's torso and extremities, and 2B is a second rectangular portion forming a vertical shield wall. The patient 12A is laid on the operating table 9A. In this example, the operating table 9A
Has no armboard. FIG. 12 is an explanatory view of the procedure for constructing the above-mentioned known surgical drape. In order to join the first rectangular portion 1B and the second rectangular portion 2B, the second rectangular portion 2B is provided with a truncated V-shaped notch 3B as shown in FIG. 12 (A). The first rectangular portion 1B is provided with a cutout 4B having the same shape as the cutout V-shaped cutout 3B, as shown in FIG. 12B. The second rectangular portion 2B is overlaid on the first rectangular portion 1B as indicated by the arrow c, and the truncated V-shaped notches 3B and 4B are overlaid and cut as shown in FIG. 12 (C). It is joined by a seam 5B along the notch. This seam 5B
As can be easily understood from FIG. 12 (C), the length dimension of is longer than the width dimension W of the first rectangular portion 1B. Two parallel lines 6B and 6B shown by chain lines in this (C) figure show the schematic positions of the lines that are bent when the operating table is covered.

As a technique for folding a part of a surgical cloth vertically to the earth, there is known "Kaifu 60-114114""cover cloth with gusset" (hereinafter referred to as a known cloth with gusset). To). FIG. 13 is an explanatory view of the known gusseted cover cloth. As shown in FIG. 4A, when a patient 2C lying on a rectangular bed-shaped operating table 1C is covered with a simple rectangular sheet-like covering cloth 3C, a curtain is provided around the upper edge of the covering cloth 3C with a stand 4C. When stretched out in a shape, it is pulled 6
This is a problem because C is generated. Therefore, a known gusseted cover cloth is configured as shown in FIG. 13 (B). That is, a rectangular sheet 7C larger than the rectangular operating table 1C is used, and cuts 8C, 8C parallel to the short side are made from each of the pair of long sides, and a square gusset cloth 9C is formed in the cuts 8C, 8C. , 9C are inserted as indicated by the additional arrows. When the above-mentioned cut 8C is inserted, the place where the dragging 6C is generated in FIG. 13A is expanded as shown in FIG. 13C, and a space F is formed by the cut of the covering cloth. The gusset cloth 9C is inserted into the cut space F in a stretched manner,
Two sides of the square gusset cloth 9C are joined to the edges of the cut to complete a three-dimensional shield wall.

[0010]

The above-mentioned publicly known techniques have respective merits and demerits, and it cannot be said to be perfect yet. That is, in the known surgical drape shown in FIGS.
It is an essential requirement that the two rectangular sheets be joined vertically and horizontally, and as a result, a relatively long joining work of a length equal to the width dimension W of the drape body 10 (upper edge 11 and lower edge) is performed. The work of joining the overlapping portion with 17) is required. For this reason, the processing equipment becomes large and expensive, and the product cost becomes expensive. The known surgical cover shown in FIG. 9 and FIG. 10 also requires a configuration in which two rectangular sheets are vertically and horizontally aligned and joined, as in the known surgical drape described above, and thus the large size is required. ， Expensive processing equipment is required and the product cost becomes high. In the known surgical drape shown in FIGS. 11 and 12, the seam 5B longer than the width dimension W of the first rectangular portion 1B has to be joined as described with reference to FIG. 12C. Large, similar to known surgical drapes and known surgical coverings,
Expensive processing equipment is required, resulting in a high product cost.
The known cover fabric with a gusset shown in FIG. 13 does not have a configuration in which two rectangular sheets are vertically and horizontally arranged and joined, but a slit 8C is inserted into one rectangular sheet 7C and a gusset cloth 9C is inserted, Since the two sides of the gusset cloth 9C are joined to the edges of the cut 8C, the length of the joining processing portion is shorter than the width dimension of the rectangular sheet 7C, and the processing equipment is small and inexpensive. Sufficient, but the above cut is a rectangular sheet 7
Since the sheet is inserted into the long side of C (parallel to the short side), the lateral width dimension of the rectangular sheet 7C is not wider than the original shape. Therefore, it is not possible to spread the patient's arm laterally to cover it. The present invention has been made in view of the above circumstances, and (a) the number of basic rectangular sheets is only one, and (b) the joining process is shorter than the width dimension of the rectangular sheets. Sufficient (thus the processing equipment is small,
(C) Light weight and low product cost, and (c) A surgical cover cloth having a sleeve part, which can spread a patient's arm laterally and cover the arm, and a method for forming the same. The purpose is to

[0011]

The basic principle of the present invention created in order to achieve the above object will be summarized as follows in comparison with FIG. 13 showing a known gusseted cover cloth. is there. In this known technique, since the cut 8C is provided in parallel with the short side of the rectangular sheet 7C as shown in FIG. 7B, the length of the cut 8C has its own limit, and as a result, it is relatively small. Only a small gusset cloth 9C could be inserted. Therefore, in the present invention, the rectangular sheet 7C is used.
Then, a cut parallel to the long side of the rectangular sheet is made, for example, a virtual cut 1h indicated by a dotted line. In this way, the cuts parallel to the long sides have less restrictions on the length dimension, and a gusset cloth (not shown) larger than the gusset cloth 9C shown in the drawing can be inserted.

As a concrete construction based on the above-mentioned principle, a surgical cloth having a sleeve portion according to the present invention is provided with a surgical table from around the portion corresponding to the shoulder of the patient when the patient is supine on the table. A cover cloth for a surgical operation used on an operating table equipped with an armboat extending laterally, which will be described with reference to FIG. 1 corresponding to one embodiment thereof. A rectangular sheet (1 ') having a width dimension larger than the width dimension of the main body part to be removed and a length dimension substantially equal to or larger than the length dimension in the longitudinal direction of the operating table is used as a basic member, and When the patient on the operating table is covered with the sheet which is the basic member, the side edges (1e, 1f) are directed from the point (a) corresponding to the vicinity of the armpit of the patient toward the upper edge (1c) of the sheet. Break parallel to (1g, 1h)
Is provided, and the length dimension of the above cut is L,
A sheet (1 ') in which L> S, where S is the distance from the point (a) to the nearest side edge, and a sheet piece having a width S and a length L cut out by the cut is a basic member. Each of two adjacent sides of a square gusset (7), which is folded back to the side of, and has a length of approximately L, is made to face each of the pair of cuts. It is characterized by being joined. However,
The above "when the patient is supine" is a precondition for defining a part corresponding to the shoulder, and this covering is an invention applicable not only to a supine patient. The method for forming a surgical cloth having sleeves according to the present invention is an arm extending laterally from the operating table from the vicinity of a portion corresponding to the shoulder of the patient when the operating table is supine. When forming a surgical cloth used on an operating table equipped with a boat, a width dimension larger than the width dimension of the main body portion of the operating table excluding the arm board and the length in the longitudinal direction of the operating table. When a rectangular sheet (1 ') having a length substantially equal to or larger than the dimension is used as a basic member and the patient on the operating table is covered with the sheet as the basic member, the armpit of the patient Cuts (1g, 1h) parallel to the side edges (1e, 1f) are provided from the point (a) corresponding to the vicinity to the upper edge (1c) of the sheet, and the length dimension of the cut is L. , S is the distance from the point (a) to the nearest side edge, > S, and the sheet piece of width S and length L cut out by the above-mentioned cut is folded back to the side of the sheet (1 ') which is a basic member, and a square having a length of one side of approximately L Each of the two adjacent sides of the gusset (7) is opposed to and joined to each of the pair of cuts of the cut.

[0013]

Referring to FIG. 1 (A) corresponding to one embodiment of the surgical cloth of the present invention having the above-mentioned constitution, from the point a corresponding to the armpit of the patient to the upper edge 1c of the sheet, the basic Cuts 1g and 1h having a length L are provided in parallel with the side edges 1e and 1f, which are the long sides of the sheet 1 '. This break 1
Since g and 1h are parallel to the long side, the length restriction is loose, and the length dimension L thereof is significantly shorter than the width dimension W of the basic sheet 1 but longer than the illustrated dimension S. Therefore, the rectangular piece 1 cut out by these cuts 1g, 1h
When j and 1k are folded back to the side, the dimension L as shown in FIG.
-Overhang only S sideways. Therefore, by inserting the gusset 7 shown with spots and joining the two sides, the arm of the patient 3 can be covered. In this case, since the length dimension of the joint portion of the gusset 7 is substantially L and is much shorter than the width dimension W of the basic sheet 1, the processing equipment is small, lightweight, inexpensive, and the processing cost is high. .

[0014]

1 and 2 are explanatory views of an example in which a surgical cover cloth having a sleeve portion according to the present invention is constituted by the method of the present invention, and FIGS. 1 (A) and 2 (A) , Fig. 2 (B),
The processing steps are shown in the order of FIG. Figure 1
Reference numeral 2 shown in (A) is a rectangular operating table, and 3 is a patient. The arm boat 5 extends laterally from the operating table 2 while being positioned near the shoulder of the patient, and the patient 3 has the arm on the arm boat 5. The dimension between the ends of the pair of arm boats 5 shown in the figure is l, and the width dimension of the main body portion (the portion excluding the arm boat 5) of the operating table 2 is Wb. In FIG. 1 (A), as a procedure for explanation, the operating table 2 is covered with a basic sheet 1 ', and the width W of the basic sheet 1'is the width W of the operating table.
It is larger than b and smaller than the distance l between both ends of the armboat. 1c is an upper edge of the basic sheet 1 ', 1d is a lower edge, and 1e and 1f are side edges. A point a near the armpit of the patient 3 is set. This point a is not a substance, but is defined as a design procedure. This point a
Has two points, the right armpit and the left armpit of patient 3,
From this point a toward the upper edge 1c, cuts 1g and 1h are made in parallel with the side edges 1e and 1f. At this time, the break 1
Let L be the length of g and 1h, and let S be the distance from each point a to the nearest side edges 1e and 1f, and set the dimensions of the relevant parts so that S <L. Reference numeral 1i shown in the drawing is an opening provided in the basic sheet 1'for an incision operation. When carrying out the present invention, the position, shape and size of the opening 1i can be set appropriately. 1g, 1 of the break
Rectangular pieces 1j and 1k are cut out by h. The width dimension of each of the pieces 1j and 1k is S, and the length dimension thereof is L. When these pieces are folded outward as shown in FIG. 2 (A) and are folded at a right angle with respect to the side edges 1e and 1f, they are folded as shown in FIG.
It becomes like (B). When folded in this manner, the pair of pieces 1j and 1k project outside the side edges 1e and 1f by the dimension L-S, respectively. Therefore, the pair of pieces 1
The distance between the ends of j and 1k is W + 2 (L−S) = W + 2
It becomes L-2S. Then, in the M area and the N area shown in FIG. 2B, a square space after the piece is folded is formed, and the dimension of one side is L. Figure 1

A square gusset 7 having a side length slightly larger than the dimension L is applied, and two sides of each gusset 7 are joined to the basic sheet 1 '(adhesive bonding in this embodiment). In this manner, the folded pieces 1j and 1k and the joined gusset 7 can cover the arm of the patient 3 and the arm board 5. The overall contour of FIG. 1B is T-shaped. That is, a T-shaped covering cloth is formed by a novel method which does not belong to any of the methods shown in FIGS. 4 (A) and 4 (B), and the length of a portion requiring a bonding operation is long. The dimension is shorter than the width dimension W of the basic sheet 1. As described above, in the present embodiment, (a) the number of rectangular sheets as a base is sufficient, and (b) the joining process shorter than the width dimension of the rectangular sheet is sufficient (therefore, the processing equipment is small in size). , (Light weight and low product cost), and (c) the patient's arm can be spread laterally to cover it. The following is a comparison of the configuration of the present embodiment described above with the above-mentioned known techniques. In the known surgical drape shown in FIGS. 3 to 8, two rectangular sheets (the lateral arm portion 16 and the body portion 10) are vertically and horizontally arranged to form a sleeve portion, and a length dimension W ( Although it was necessary to perform the joining operation of the sheet width), in this embodiment, one basic sheet 1'is used.
And the two gussets 7 have a joint length of about dimension L, which is significantly shorter than the dimension W. Figure 9,
The known surgical cover shown in FIG. 10 also includes two sheets (1
4A, 15A) are arranged vertically and horizontally to join a long distance. In this embodiment, one basic sheet 1'and two gussets 7 are constructed by a joining operation of a relatively short dimension L. You can

In the known surgical drape shown in FIGS. 11 and 12, two rectangular portions (1B, 2B) are vertically and horizontally arranged and joined along a joint 5B longer than the width W of the rectangular portion 1B. However, in the present embodiment, one basic sheet 1'and two gussets 7 can be configured to be joined at a joining portion length L <W. In the known gusseted cover cloth shown in FIG. 13, the cut 8C is provided in parallel with the short side of the rectangular sheet 7C as shown in FIG. I couldn't do it,
