Description

[Technical field]

[0001] The present invention relates to a medical drape that is placed over a patient during surgery. [Background technology]

[0002] In recent catheter treatments, long devices such as long catheters and guidewires are required. For example, when performing catheter treatment of a lower limb artery by inserting a long device from the radial artery, it is necessary to use a long device. However, there is a possibility that the long device may fall off the operating table during the procedure, become dirty, and need to be replaced. Therefore, for example, Patent Document 1 describes a storage device including a tube into which a long device can be inserted that can be fixed to a drape that is placed over a patient during treatment so as to prevent the long device from falling off during the procedure. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2001-353226 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a device that prevents a patient from falling off an operating table by inserting a long device into a tube, it is time-consuming to insert the long device into a thin tube, and the long device inserted into the tube hinders the surgeon from inserting, removing, rotating, and other operations of the long device into a blood vessel, which may cause a delay in the procedure.

[0005] The present invention has been made to solve the above-mentioned problems, and aims to provide a medical drape that can prevent an elongated device from falling off the operating table while maintaining the surgeon's operability of the elongated device. [Means for solving the problem]

[0006] The above object can be achieved by the invention described in (1) below. (1) The medical drape of the present invention is a medical drape used when inserting a long device into a patient's blood vessel, and is characterized in having a sheet portion having a front and a back surface, at least one opening that penetrates from the front surface to the back surface of the sheet portion, and at least one balloon that is disposed on the sheet portion and is expandable so as to protrude from the front surface of the sheet portion. Effect of the Invention

[0007] The medical drape described in (1) above can prevent the long device from falling off the operating table by the balloon protruding from the surface. In addition, the medical drape can maintain the operability of the long device because the balloon does not interfere with the operation of the long device by the surgeon.

[0008] (2) In the medical drape described in (1) above, the balloons may be multiple, and at least two of the balloons may be arranged side by side at intervals along the arrangement direction, which is the direction away from the opening, on the surface. In this way, the medical drape can effectively prevent the elongated device, which is led out of the patient's body from the surgical site and extends in the arrangement direction, from falling off the operating table by the multiple balloons. In addition, since the multiple balloons are arranged at intervals, the surgeon can easily grasp the elongated device between the adjacent balloons.

[0009] (3) In the medical drape described in (1) or (2) above, at least one of the balloons may be formed to be elongated in an arrangement direction that is a direction away from the opening on the surface, whereby the medical drape can effectively prevent the elongated device, which is led out from the surgical site and extends long in the arrangement direction, from falling off the operating table by the elongated balloon.

[0010] (4) In the medical drape described in any one of (1) to (3) above, the balloon may have an apex in an upward direction perpendicular to the arrangement direction on the surface, and an inner side extending from the surface of the sheet part to the apex and facing an inward direction perpendicular to the arrangement direction toward the center of the sheet part along the surface of the sheet part, and the inner side may have a curved surface recessed in the opposite direction to the inward direction. This allows the medical drape to prevent the balloon from moving the elongated device outward and dropping it. In addition, the medical drape is less likely to hinder the surgeon's actions of lifting the elongated device upward or moving it inward toward the patient, thereby improving the surgeon's operability of the elongated device.

[0011] (5) In the medical drape described in any one of (1) to (4) above, the balloon may have an injection port that extends from the surface of the sheet portion to the apex of the balloon in a cross section perpendicular to the arrangement direction, which is a direction on the surface away from the opening, and that injects a fluid for expanding the balloon in an outward direction, which is a direction away from the center of the sheet portion along the surface of the sheet portion and perpendicular to the arrangement direction. This allows the injection port to be located at a position that is easy for a surgeon to operate during surgery, improving workability.

[0012] (6) In the medical drape described in any one of (1) to (5) above, the sheet portion may have a mountain fold position indicator for indicating a position where the surface can be mountain folded, and a valley fold position indicator for indicating a position where the surface can be valley folded, on the surface in a direction away from the opening on the surface and on the arrangement direction side where the balloon is arranged. As a result, the medical drape can be folded at the mountain fold position indicator and the valley fold position indicator to change the extension direction of the balloon on the arrangement direction side of the opening. Therefore, the medical drape can change the extension direction of the elongated device toward the base end side depending on the procedure, the type of elongated device, the arrangement of the operating room, etc.

[0013] (7) In the medical drape described in any one of (1) to (6) above, the balloon may have a turned portion that protrudes from near the apex in the upward direction perpendicular to the arrangement direction, which is the direction away from the opening on the surface, toward the inside, which is the direction along the surface of the sheet portion and toward the center of the sheet portion perpendicular to the arrangement direction, in a cross section perpendicular to the arrangement direction of the balloon. This allows the medical drape to effectively prevent the elongated device from moving in the direction opposite to the inward direction beyond the apex and falling off the operating table.

[0014] (8) In the medical drape described in any one of (1) to (7) above, at least one of the balloons may have a groove extending on the surface facing upward, i.e., in a direction perpendicular to the surface, in a placement direction away from the opening. This allows the medical drape to hold an elongated device that is led out of the surgical site and extends long in the placement direction in the balloon groove, thereby preventing the elongated device from falling off the operating table.

[0015] (9) In the medical drape described in (8) above, the bottom surface of the groove may be formed to have a height from the surface of the sheet portion, whereby the elongated device held on the bottom surface of the balloon is positioned away from the surface of the sheet portion, making it easier for the surgeon to grasp the elongated device.

[0016] (10) In the medical drape described in (8) or (9) above, at least one of the balloons having the groove may have at least one recess in a bottom surface of the groove, whereby the elongated device housed in the groove is positioned at a position away from the bottom of the recess, making it easier for the surgeon to grasp the elongated device.

[0017] (11) In the medical drape according to any one of (8) to (10) above, at least one of the balloons having the groove may have two side walls sandwiching the groove, and the side walls may have a high wall portion and a low wall portion that is lower in height from the surface than the high wall portion. This allows the medical drape to favorably hold the elongated device in the groove by the high wall portion, while allowing the surgeon to easily grasp the elongated device by the low wall portion.

[0018] (12) In the medical drape according to any one of (1) to (11) above, at least one of the balloons may have a through-hole formed on the surface in a direction away from the opening. This allows the medical drape to hold an elongated device by passing it through the through-hole of the balloon. Therefore, the medical drape can effectively prevent the elongated device, which is led out of the surgical site and extends long in the arrangement direction, from falling.

[0019] (13) The medical drape according to any one of (1) to (12) above may have a communication tube that connects the insides of the multiple balloons. This allows the surgeon to inflate multiple balloons that are connected by the communication tube at the same time. In addition, the medical drape does not require an injection port to be provided in each balloon, and can be manufactured at low cost. [Brief description of the drawings]

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that dimensions in the drawings may be exaggerated and may differ from actual dimensions for convenience of description. In addition, in this specification and the drawings, components having substantially the same functions are given the same reference numerals to avoid repeated description. In this specification, the head direction of a patient lying on an operating table 110 (see FIG. 2) is referred to as the forward direction, the foot direction is referred to as the rearward direction, the forward or rearward direction is referred to as the front-rear direction, the left and right directions of a patient lying on his / her back on the operating table 110 are referred to as the left and right directions, respectively, and the left or right direction is referred to as the left-right direction.

[0022] First Embodiment The medical drape 10 of the first embodiment is used to cover a patient lying on an operating table 110 and keep the surface 21 of the medical drape 10 in a clean area when inserting a long device 100 such as a catheter or guidewire into the blood vessel of the patient.

[0023] As shown in FIGS. 1 to 3, the medical drape 10 has a sheet portion 20, at least one opening 30 (two in this embodiment), and at least one balloon 40 (a plurality of balloons in this embodiment).

[0024] The sheet portion 20 is a flexible sheet that covers the patient. The sheet portion 20 has a front surface 21 that faces the upward direction Z1 when placed on the operating table 110, and a back surface 22 that faces the downward direction Z2. The sheet portion 20 has a rectangular shape, and side edge portions 23 are formed on both the left and right sides. When the medical drape 10 is in use, the side edge portions 23 are arranged to hang down from the upper surface of the operating table 110 in the downward direction Z2. In this specification, when the medical drape 10 is placed on the operating table 110, the direction vertically away from the surface 21 of the sheet portion 20 is referred to as the upward direction Z1, the direction opposite to the upward direction Z1 is referred to as the downward direction Z2, the direction along the surface 21 of the sheet portion 20 and coinciding with the left-right direction is referred to as the width direction Y, the direction in the width direction Y from the side edge 23 toward the center of the sheet portion 20 is referred to as the inward direction Y1, and the direction in the width direction Y from the center of the sheet portion 20 toward the side edge 23 is referred to as the outward direction Y2.

[0025] The material forming the sheet portion 20 is, for example, a woven or nonwoven fabric made of natural or synthetic fibers, a synthetic resin sheet made of synthetic resin such as polyethylene, or a paper sheet made of paper. The sheet portion 20 may also be formed of a plurality of materials. The sheet portion 20 may be formed of a single layer, or may be formed of multiple layers. The sheet portion 20 may be entirely transparent, partially transparent, or entirely opaque.

[0026] The opening 30 is a hole formed penetrating the sheet part 20 from the front surface 21 to the back surface 22 in order to expose the surgical site where the long device 100 is to be inserted in the patient. The position and shape of the opening 30 in the medical drape 10 are not particularly limited and may be appropriately set according to the position of the surgical site. In this embodiment, two openings 30 are formed on the front side of a center part equidistant from the front end and the rear end in the front-rear direction of the sheet part 20, sandwiching a center part equidistant from the left end and the right end in the left-right direction. In this embodiment, the shape of the opening 30 is a rectangle, but it may be a circle, a triangle, or another shape.

[0027] The sheet portion 20 has a plurality of balloons 40 arranged on the surface 21 in a line from each opening 30 toward the arrangement direction X. The balloon 40 arranged most forward among the plurality of balloons 40 is arranged adjacent to the outer side Y2 side of the opening 30. The plurality of balloons 40 are arranged linearly toward the arrangement direction X with a predetermined interval therebetween. In this embodiment, the medical drape 10 is used so that the arrangement direction X is approximately the same as the rear direction. Each balloon 40 is expandable so as to protrude in the upward direction Z1 perpendicularly away from the surface 21 of the sheet portion 20. In addition, the medical drape 10 is used so that the width direction Y, which is a direction along the surface 21 and perpendicular to the arrangement direction X, is aligned with the left-right direction. Each balloon 40 has a flexible balloon main body 41A and a covering portion 41B that covers the surface of the balloon main body 41A on the upward direction Z1 side. The balloon body 41A is preferably made of a material that can be easily cut so that it can be easily deflated when the medical drape 10 is discarded. The material from which the balloon body 41A is made is, for example, rubber, thermoplastic elastomer, or flexible resin such as polyvinyl chloride. The covering portion 41B is preferably made of the same material as the sheet portion 20 so as to generate an appropriate frictional force against the elongated device 100. The covering portion 41B may be made of a material different from that of the sheet portion 20. Alternatively, the balloon body 41A does not have to be covered by the covering portion 41B.

[0028] A plurality of balloons 40 arranged in the arrangement direction X from each opening 30 form one balloon group 50. In this embodiment, two balloon groups 50 are arranged on the sheet portion 20 symmetrically and in parallel. The two balloon groups 50 are arranged such that the balloon 40 arranged most forward is adjacent to the opening 30 in the outer direction Y2. The two balloon groups 50 are arranged so that they are located on the upper surface of the operating table when the medical drape 10 covers the patient. In this way, the two balloon groups 50 prevent the elongated device 100 from moving in the outer direction Y2 and falling off the upper surface of the operating table 110.

[0029] 3, in a cross section perpendicular to the arrangement direction X, each balloon 40 has an apex 42 in the upward direction Z1, an inner side surface 43 extending from the surface 21 of the sheet portion 20 to the apex 42 and facing the inward direction Y1 of the sheet portion 20, an outer side surface 44 facing from the apex 42 to the outward direction Y2 of the sheet portion 20, and an injection port 45 disposed in the outer side surface 44. Each balloon 40 protrudes from the surface 21 in the upward direction Z1. However, the direction in which each balloon 40 protrudes does not have to be perpendicular to the surface 21 as long as the apex 42 of the balloon 40 is a direction away from the surface 21.

[0030] The inner surface 43 is a surface facing the inward direction Y1, and is formed as a curved surface recessed toward the outward direction Y2 in a cross section perpendicular to the arrangement direction X. Therefore, the elongated device 100 is held near the intersection of the inner surface 43 of the balloon 40 and the sheet part 20 so as to have a movable range of at least 90 degrees including the inward direction Y1 and the upward direction Z1. As a result, the balloon 40 prevents the elongated device 100 from moving in the outward direction Y2 and falling off the operating table 110, while not interfering with the surgeon's actions of lifting the elongated device 100 in the upward direction Z1 or moving it in the inward direction Y1 toward the patient, and therefore does not impair the surgeon's operability.

[0031] The inlet 45 is a portion that connects the inside and outside of the balloon 40. The inlet 45 can be connected to an injection device such as a manual pump or a syringe. The inlet 45 has a check valve that allows injection of a fluid (e.g., air) into the balloon 40 for expanding the balloon 40, while preventing the fluid from being discharged from the inside of the balloon 40 to the outside. The inlet 45 is located on the outer surface 44 of the balloon 40 close to where the surgeon stands during the procedure, making it easy for the surgeon to operate.

[0032] Next, a method of using the medical drape 10 according to the first embodiment will be described.

[0033] 2, the surgeon positions the opening 30 so that the surgical site (the site where the elongated device can be inserted into the radial artery) of the left and / or right hand of the patient lying on his / her back on the operating table 110 is exposed, and places the medical drape 10 over the patient. In this way, the two balloon groups 50 are positioned on either side of the patient in the left and right directions. The two balloon groups 50 are positioned near the left and right edges of the operating table 110.

[0034] The surgeon connects a manual pump, a syringe, or the like to the injection port 45 of each balloon 40 and injects a fluid such as air into the balloon 40 to expand the balloon 40. The injection port 45 has a check valve, so that the balloon 40 can be maintained in an expanded state. The surgeon may inflate only the necessary balloons 40 depending on the purpose.

[0035] The surgeon inserts and removes the elongated device 100 from the surgical site, rotates it, and performs other operations between the two balloon groups 50. The balloons 40 of each balloon group 50 are arranged in a line from a position on the outer side Y2 of the opening 30 toward the arrangement direction X, so that the outer side Y2 of the elongated device 100 can be held as it is led out of the patient's body from the surgical site and extends in the arrangement direction X (rearward). As a result, the medical drape 10 can prevent the elongated device 100 from falling off the operating table 110 by the two balloon groups 50, so that the replacement of the elongated device 100 can be prevented. Furthermore, the medical drape 10 can prevent the elongated device 100 from falling off without the need for an assistant to hold the rear end side of the elongated device 100 or an assistant such as gauze, so that the manpower required for the procedure can be reduced and waste can be reduced.

[0036] After the surgery is completed, the surgeon cuts the balloon 40 with scissors or the like to release the air from the balloon 40. This allows the medical drape 10 according to this embodiment to be disposed of in approximately the same amount as a medical drape not provided with a balloon.

[0037] As described above, the medical drape 10 according to the first embodiment is a medical drape 10 used when inserting the elongated device 100 into a patient's blood vessel, and includes a sheet portion 20 having a front surface 21 and a back surface 22, at least one opening 30 penetrating from the front surface 21 to the back surface 22 of the sheet portion 20, and at least one balloon 40 disposed on the sheet portion 20 and capable of expanding so as to protrude from the front surface 21 of the sheet portion 20. This allows the medical drape 10 to prevent the elongated device 100 from falling off the operating table 110 by the balloon 40 protruding from the front surface 21. Furthermore, the medical drape 10 maintains the operability of the elongated device 100 because the balloon 40 does not easily interfere with the operation of the elongated device 100 by the surgeon.

[0038] Furthermore, in this medical drape 10, there are multiple balloons 40, and at least two of the balloons 40 are arranged side by side at intervals along the arrangement direction X, which is the direction away from the opening 30, on the surface 21. In this way, the medical drape 10 can effectively prevent the elongated device 100, which is led out of the patient's body from the surgical site and extends in the arrangement direction X, from falling off the operating table 110 by the multiple balloons 40. Furthermore, since the multiple balloons 40 are arranged at intervals, the surgeon can easily grasp the elongated device 100 between adjacent balloons 40.

[0039] Moreover, in a cross section perpendicular to the arrangement direction X, which is a direction away from the opening 30 on the surface 21, the balloon 40 has an apex 42 in an upward direction Z1, which is a direction perpendicular to the surface 21, and an inner side surface 43 that extends from the surface 21 of the sheet part 20 to the apex 42 and faces an inner direction Y1, which is a direction along the surface 21 of the sheet part 20 and perpendicular to the arrangement direction X toward the center of the sheet part 20, and the inner side surface 43 has a curved surface that is recessed in the opposite direction to the inner direction Y1 (outer direction Y2). This allows the medical drape 10 to suppress the movement of the elongated device 100 in the outer direction Y2 and falling off due to the balloon 40. Furthermore, the medical drape 10 is unlikely to hinder the operator's actions of lifting the elongated device 100 in the upward direction Z1 or moving it in the inner direction Y1 toward the patient side, thereby improving the operability of the elongated device 10 by the operator.

[0040] Moreover, the balloon 40 has an injection port 45 that extends from the surface 21 of the sheet portion 20 to the apex 42 of the balloon 40 in a cross section perpendicular to the arrangement direction X, which is a direction on the surface 21 away from the opening 30, and that injects a fluid for expanding the balloon 40 in the outward direction Y2, which is a direction away from the center of the sheet portion 20 along the surface 21 of the sheet portion 20 and perpendicular to the arrangement direction X. This allows the injection port 45 to be placed at a position that is easy for the surgeon to operate during surgery, improving workability.

[0041] <Second embodiment> The medical drape 10 according to the second embodiment differs from the first embodiment only in that it can be easily folded for use.

[0042] As shown in FIG. 4, the sheet portion 20 has a folding position display section 24 that indicates a folding position so that the direction in which the balloons 40 of each balloon group 50 are arranged can be bent. The folding position display section 24 has a mountain fold position display section 25 that displays a mountain fold position, and a valley fold position display section 26 that displays a valley fold position. As an example, the sheet portion 20 has one mountain fold position display section 25 displayed as a straight line extending in the width direction Y and multiple valley fold position display sections 26 displayed as straight lines inclined at slightly different angles to the mountain fold position display section 25, formed on the arrangement direction X side of the opening 30 and in the middle of the balloon group 50. The mountain fold position display section 25 and the valley fold position display section 26 overlap at one side end of the sheet portion 20 in the width direction Y, but they do not necessarily have to overlap. The mountain fold position display section 25 and the valley fold position display section 26 may be displayed as lines of different colors or lines of different shapes, such as solid lines and dashed lines, so that the surgeon can easily distinguish them. The mountain fold position display section 25 and the valley fold position display section 26 may be displayed by a curved line. The mountain fold position display section 25 and the valley fold position display section 26 may display the positions where the mountain fold and the valley fold are possible as marks provided on the side edge sections 23 on both sides of the sheet section 20. The mountain fold position display section 25 and the valley fold position display section 26 may display a description of the mountain fold position, the valley fold position, the angle, etc. in text in addition to a straight line or a mark. In this embodiment, there is one mountain fold position display section 25 and multiple valley fold position display sections 26, but there may be one mountain fold position display section 25 and one valley fold position display section 26, multiple mountain fold position display sections 25 and one valley fold position display section 26, or multiple mountain fold position display sections 25 and multiple valley fold position display sections 26. The folding position display section 24 is preferably disposed at a position that does not overlap with the balloon 40 so as not to interfere with folding. Furthermore, the balloon 40 does not have to be placed on the surface 21 at a position where the surfaces 21 overlap each other when the folding position indicator 24 is folded.

[0043] Next, a method of using the medical drape 10 according to the second embodiment will be described.

[0044] The surgeon positions the opening 30 so that the operative site of the left and / or right hand of the patient lying on his / her back on the operating table 110 is exposed, and places the medical drape 10 on the patient. Next, the surgeon selects the mountain fold position display section 25 and the valley fold position display section 26 to fold the sheet section 20 so that the balloon group 50 is bent at a desired angle according to the purpose. Next, the surgeon injects air from the injection port 45 of the required balloon 40, and expands the balloon 40 as shown in FIG. 5. At this time, since the balloons 40 can be expanded individually, the surgeon can select and expand only the balloons 40 required to hold the elongated device 100, without expanding the balloons 40 arranged at the overlapping position of the sheet section 20. As a result, the medical drape 10 can appropriately hold the elongated device 100 so that it does not fall off the operating table 110 by each balloon group 50 that is bent at a desired angle.

[0045] As described above, in the medical drape 10 according to the second embodiment, the sheet portion 20 has a mountain fold position indicator 25 that indicates a position at which the surface 21 can be mountain folded, and a valley fold position indicator 26 that indicates a position at which the surface 21 can be valley folded, on the surface 21 in the direction away from the opening 30 along the surface 21 and on the arrangement direction X side on which the balloon 40 is arranged. As a result, the medical drape 10 can change the extension direction of the balloon 40 on the arrangement direction X side of the opening 30 by folding at the mountain fold position indicator 25 and the valley fold position indicator 26. Therefore, the medical drape 10 can change the direction in which the elongated device 100 extends toward the base end side depending on the procedure, the type of elongated device 100, the arrangement of the operating room, and the like.

[0046] <Third embodiment> The medical drape 10 according to the third embodiment differs from the first embodiment only in the shape of the balloon 40 near the top 42 thereof.

[0047] 6, each balloon 40 in the third embodiment has a turned portion 46 protruding in the inward direction Y1 near the apex 42. The turned portion 46 allows fluid to flow therein, but may be formed so that fluid cannot flow therein.

[0048] As described above, in the medical drape 10 according to the third embodiment, the balloon 40 has a turned portion 46 that, in a cross section perpendicular to the arrangement direction X, which is the direction on the surface 21 away from the opening 30, protrudes from near the apex 42 in the upward direction Z1, which is the direction perpendicularly away from the surface 21, toward the inward direction Y1, which is the direction along the surface 21 of the sheet portion 20 and perpendicular to the arrangement direction X toward the center of the sheet portion 20. As a result, the medical drape 10 can effectively prevent the elongated device 100 from falling off the operating table 110 by the turned portion 46 of the balloon 40.

[0049] The turned portion 46 may be formed on only some of the multiple balloons 40. Therefore, the medical drape 10 may have a balloon 40 having a turned portion 46 and a balloon 40 of another embodiment. The medical drape 10 can effectively prevent the elongated device 100 from falling off the operating table 110 in the vicinity of the balloon 40 having the turned portion 46.

[0050] <Fourth embodiment> The medical drape 10 of the fourth embodiment differs from the first embodiment in that the position at which the balloon 40 holds the elongated device 100 is away from the surface 21 of the sheet portion 20 in the upward direction Z1, as shown in Figures 7(A) and (B).

[0051] Each balloon 40 in the fourth embodiment has a groove portion 47 that opens in the upward direction Z1 on the surface facing the upward direction Z1. The groove portion 47 is formed in a groove shape along the arrangement direction X from the front end surface to the rear end surface of each balloon 40. The bottom surface 48 of the groove portion 47 closest to the surface 21 of the sheet portion 20 is formed at a predetermined height H from the surface 21. The heights H of the balloons 40 lined up in the arrangement direction X are equal to each other, but may be different. It is also possible to form the balloon 40 so that the bottom surface 48 is at the same height as the surface 21 of the sheet portion 20, as in the modified example shown in FIG. 7(C).

[0052] When using the medical drape 10 according to the fourth embodiment, the surgeon can place the elongated device 100 extending from the opening 30 in the arrangement direction X in the groove portion 47 of each balloon 40, as shown in Figures 7(A) and (B). The elongated device 100 placed in the groove portion 47 is held at a predetermined height H from the surface 21 of the sheet portion 20 of the multiple balloons 40 arranged at intervals. This allows the surgeon to easily grasp the elongated device 100 that is placed away from the surface 21 of the sheet portion 20 between adjacent balloons 40.

[0053] The grooves 47 may be formed in only some of the multiple balloons 40. Therefore, the medical drape 10 may include a balloon 40 having a groove 47 and a balloon 40 of another embodiment.

[0054] As described above, in the medical drape 10 according to the fourth embodiment, at least one balloon 40 has a groove 47 extending on the surface 21 in the arrangement direction X, which is a direction away from the opening 30, on a surface facing the upward direction Z1, which is a direction perpendicular to the surface 21. This allows the medical drape 10 to hold the elongated device 100, which is derived from the surgical site and extends long in the arrangement direction X, in the groove 47 of the balloon 40, and prevents the elongated device 100 from falling off the operating table 110.

[0055] In addition, the bottom surface 48 of the groove portion 47 is formed to have a height H from the surface 21 of the sheet portion 20. As a result, the elongated device 100 held on the bottom surface 48 of the balloon 40 is positioned away from the surface 21 of the sheet portion 20, making it easy for the surgeon to grasp the elongated device 100.

[0056] <Fifth embodiment> The medical drape 10 according to the fifth embodiment differs from the first embodiment in that it has two long balloons 40 extending in the arrangement direction X, as shown in FIGS.

[0057] In the fifth embodiment, a long balloon 40 is formed extending in the arrangement direction X from each opening 30 along the surface 21 of the sheet portion 20. The long balloon 40 is formed so that the length in the arrangement direction X is longer than the width in the width direction Y. The number of balloons 40 provided on the surface 21 of the sheet portion 20 may be only one, or may be three or more.

[0058] Each balloon 40 has a groove portion 47 that opens in the upward direction Z1 on the surface facing the upward direction Z1. The groove portion 47 is formed in a groove shape along the arrangement direction X from the front end surface to the rear end surface of each balloon 40. At least one (multiple in this embodiment) recessed portion 49 that opens in the upward direction Z1 is formed in the groove portion 47 at intervals in the upward direction Z1.

[0059] When using the medical drape 10 according to the fifth embodiment, the surgeon can place the elongated device 100 extending from the opening 30 in the arrangement direction X in the groove 47 of the balloon 40 located on the arrangement direction X side of the opening 30. When held in the groove 47, the elongated device 100 is separated from the bottom of the recess 49. Therefore, the surgeon can easily grasp the elongated device 100 placed in the groove 47 by using the recess 49.

[0060] As described above, in the medical drape 10 according to the fifth embodiment, at least one of the balloons 40 is formed to be long on the surface 21 in the arrangement direction X, which is the direction away from the opening 30. In this way, the medical drape 10 can effectively prevent the elongated device 10, which is led out of the surgical site and extends long in the arrangement direction X, from falling off the operating table 110 by the long balloon 40.

[0061] Furthermore, in the medical drape 10 according to the fifth embodiment, at least one of the balloons 40 having a groove 47 has at least one recess 49 on a bottom surface 48 of the groove 47. This allows the elongated device 100 housed in the groove 47 to be positioned away from the bottom of the recess 49 at the position of the recess 49, making it easy for the surgeon to grasp the elongated device 100.

[0062] Sixth embodiment The medical drape 10 according to the sixth embodiment differs from the fifth embodiment in that the height of the two long balloons 40 extending in the arrangement direction X varies depending on the position in the arrangement direction X, as shown in FIGS.

[0063] In the sixth embodiment, one long groove portion 47 is formed extending from each opening 30 along the surface 21 of the sheet portion 20 in the arrangement direction X. Each balloon 40 has a groove portion 47 that opens in the upward direction Z1 on the surface facing the arrangement direction X. The groove portion 47 is formed in a groove shape between two side walls 60 from the front end surface to the rear end surface of each balloon 40. The height H of the bottom surface 48 of the groove portion 47 is approximately constant along the arrangement direction X. In the two side walls 60, high wall portions 61 having a high height H1 in the upward direction from the surface 21 and low wall portions 62 having a height H2 lower than that of the high wall portion 61 are alternately arranged in the arrangement direction X. The number of each of the high wall portions 61 and the low wall portions 62 may be one or more. A height H2 of the low wall portion 62 in the upward direction Z1 from the surface 21 is higher than a height H of the bottom surface 48 of the groove portion 47, but may be equal to or lower than the height H of the bottom surface 48 of the groove portion 47. The high wall portion 61 can favorably hold the elongated device 100 in the groove portion 47. The low wall portion 62 can make it easier for the surgeon to grasp the elongated device 100.

[0064] The bottom wall portion 62 of each balloon 40 is preferably provided on the side wall 60 closest to where the surgeon stands during the procedure. When the bottom wall portions 62 are provided on two side walls 60 that face each other across the groove portion 47 of each balloon 40, the bottom wall portions 62 are preferably provided at positions that face each other across the groove portion 47. It is preferable that they are aligned. This makes it easier for the surgeon to grasp the elongated device 100.

[0065] When using the medical drape 10 according to the sixth embodiment, the surgeon can place the elongated device 100 extending from the opening 30 in the arrangement direction X in the groove portion 47 of the balloon 40 located in the arrangement direction X of the opening 30. The high wall portion 61 formed in the balloon 40 of the medical drape 10 can prevent the elongated device 100 from moving out of the groove portion 47 of the balloon 40 and falling off the operating table 110. In addition, the surgeon can easily grasp the elongated device 100 at the position of the low wall portion 62 provided on the side wall 60 of the balloon 40.

[0066] In the medical drape 10 according to the sixth embodiment, at least one of the balloons 40 having a groove portion 47 has two side walls 60 sandwiching the groove portion 47, and the side walls 60 have a high wall portion 61 and a low wall portion 62 that is lower in height from the surface 21 than the high wall portion 61. This allows the medical drape 10 to favorably hold the elongated device 100 in the groove portion 47 with the high wall portion 61, while allowing the surgeon to easily grasp the elongated device 100 with the low wall portion 62.

[0067] Seventh embodiment As shown in FIGS. 12 and 13(A), the medical drape 10 according to the seventh embodiment differs from the first embodiment in that each balloon 40 is formed in a cylindrical shape.

[0068] In the medical drape 10 according to the seventh embodiment, a plurality of balloons 40 are arranged side by side from each opening 30 along the surface 21 of the sheet portion 20. Each balloon 40 has a through hole 70 formed therethrough in the arrangement direction X. The through hole 70 is formed between the arc-shaped balloon 40 and the surface 21 of the sheet portion 20, and has a semicircular shape in a cross section perpendicular to the arrangement direction X. Both ends of the arc shape of the balloon 40 are fixed to the sheet portion 20. Note that the shape of the balloon 40 does not have to be an arc shape in a cross section perpendicular to the arrangement direction X as long as the through hole 70 can be formed, and may be, for example, a polygonal shape in a cross section perpendicular to the arrangement direction X. In this case, the shape of the through hole 70 may be a prismatic shape (such as a triangular prism or a quadrangular prism).

[0069] When using the medical drape 10 according to the seventh embodiment, the surgeon can place the elongated device 100 extending from the opening 30 in the arrangement direction X through the through-holes 70 of each balloon 40 located in the arrangement direction X of the opening 30. Since the elongated device 100 is surrounded by the balloons 40 and the sheet portion 20, it is prevented from falling off the operating table 110.

[0070] As described above, in the medical drape 10 according to the seventh embodiment, at least one of the balloons 40 forms a through-hole 70 penetrating on the surface 21 in a direction away from the opening 30. This allows the medical drape 10 to hold the elongated device 100 by passing it through the through-hole 70 of the balloon 40. Therefore, the medical drape 10 can effectively prevent the elongated device 100 from falling as it is led out of the surgical site and extends long in the arrangement direction X.

[0071] 13(B), only one end of the balloon 40 in the outer direction Y2 of the arc shape may be fixed to the sheet portion 20. The surgeon can easily accommodate the elongated device 100 in the through-hole 70 by deforming the balloon 40 so as to widen the through-hole 70. Even if the balloon 40 is deformed, it can return to its original shape by its own restoring force, so that the elongated device 100 can be easily accommodated and held in the through-hole 70.

[0072] The present invention is not limited to the above-described embodiment, and various modifications can be made by those skilled in the art within the technical concept of the present invention. For example, as in the modified example shown in Fig. 14, the medical drape 10 may have a communication tube 80 that connects the insides of the multiple balloons 40. This allows the surgeon to inflate the multiple balloons 40 that are connected by the communication tube 80 at the same time. In addition, the medical drape 10 does not require the provision of an injection port 45 in each balloon 40, and can be manufactured at low cost.

[0073] In each of the above-described embodiments, the direction in which the balloon 40 extends on the surface 21 may be curved toward the arrangement direction X. In addition, the configurations of each of the above-described embodiments may be appropriately combined. [Explanation of symbols]
