For this reason, not only the liquid flowing from the surgical site to the left and right sides but also the liquid flowing in the longitudinal direction (in this embodiment, flowing toward the patient's head) can be received by the pouch 2.

  As shown in FIG. 6, the pouch body 21 includes a first pouch sheet 22 and a second pouch sheet 23. The first pouch sheet 22 is fixed to the first sheet body 121 with a double-sided tape or the like around the opening 110 on the clean surface 111 of the first drape sheet 12. Further, a portion of the first pouch sheet 22 near the end on the opening 110 side is sandwiched between the first opening sheet 125 and the first sheet main body 121 and joined to the first opening sheet 125. In FIG. 6, in order to facilitate understanding of the drawing, the joint portion of the first sheet main body 121, the first pouch sheet 22, and the first opening sheet 125 is drawn while being separated in the vertical direction.

  The second pouch sheet 23 is laminated on the opposite side of the first pouch sheet 22 from the first drape sheet 12, and continues to the first pouch sheet 22 at the edge farther from the opening 110. The first pouch sheet 22 and the second pouch sheet 23 may be formed by folding one sheet member in half, or may be formed by joining edges of two sheet members. The first pouch sheet 22 and the second pouch sheet 23 are formed of a transparent or translucent flexible resin material such as polyethylene.

  An edge 231 closer to the opening 110 of the second pouch sheet 23 has a shape that substantially conforms to the outer shape of the pouch 2 and is separated from the opening 110. The edge 231 is provided with a band-shaped shape retaining member 232 formed of a resin such as polyethylene that can be easily plastically deformed (that is, the shape can be easily changed). In the pouch 2, the shape retaining member 232 is plastically deformed, so that the edge 231 of the second pouch sheet 23 is greatly separated from the first pouch sheet 22, as depicted by a two-dot chain line in FIG. A liquid receiving port 210 for receiving the liquid is formed.

  As shown in FIG. 1, the pouch main body 21 has two drainage ports 25 arranged at positions farthest from the opening 110 on both the left and right sides of the opening 110 (that is, one and the other in the left-right direction). In the present embodiment, the two drainage ports 25 are formed in the first pouch sheet 22 in the vicinity of the two vertices farthest from the opening 110 of the pouch body 21 having a substantially hexagonal shape. The liquid discharge port 25 discharges the liquid that has flowed into the pouch body 21 from the liquid reception port 210. As shown in FIG. 6, each first drainage pipe 24 protrudes from the drainage port 25 of the pouch body 21 toward the first drape sheet 12.

  The drape 1 further includes two substantially cylindrical second drainage pipes 31 respectively connected to the two first drainage pipes 24 of the pouch 2. Each second drain pipe 31 is fitted to the outside of the first drain pipe 24. In the following description, the first drainage pipe 24 and the second drainage pipe 31 are collectively referred to as “drainage pipe 3”. The two drainage pipes 3 are connected to the two drainage ports 25 of the pouch body 21, respectively.

  As shown in FIGS. 1 and 6, in the drape main body 11, the second drainage liquid is provided on the first drape sheet 12 on the side opposite to the opening 110 of each drainage port 25 and in the vicinity of each drainage port 25. A through hole 129 larger than the outer diameter of the tube 31 is provided. In the present embodiment, the through hole 129 is substantially circular. The shortest distance between the through hole 129 and the drainage port 25 is preferably 10 cm or less, and more preferably 5 cm or less. The two through holes 129 arranged on the left and right sides of the opening 110 (that is, one and the other in the left and right direction) are respectively covered with two substantially rectangular through hole sheets 128 joined to the clean surface 111 of the drape body 11. Is called. The through hole sheet 128 is a stretchable sheet member, and has a cross shape smaller than the outer diameter of the second drainage pipe 31 at the central portion of the portion facing the through hole 129 of the through hole sheet 128. A notch is provided. Instead of the cross-shaped cut, for example, a substantially circular hole smaller than the outer diameter of the second drainage pipe 31 may be provided in the through hole sheet 128.

  In the drape 1, as shown in FIG. 6, the second drainage pipe 31 of the drainage pipe 3 is inserted into the cut of the through-hole sheet 128 from the clean surface 111 side, so that the cut is expanded. It becomes the elastic insertion port 127. If the above-mentioned notch of the through-hole sheet 128 is regarded as a stretchable insertion port 127 when the through-hole sheet 128 is not stretched, the area of the stretchable insertion port 127 when not stretched is the cross section of the second drainage pipe 31. Smaller than. In the drape 1, each drainage pipe 3 is inserted into the stretchable insertion port 127 of the through hole sheet 128, and from the clean surface 111 side of the drape main body 11 to the dirty surface 112 side through the through hole 129 of the drape main body 11. It extends.

  A hole peripheral portion 128a that is a portion around the stretchable insertion port 127 of the through hole sheet 128 is pushed out toward the dirty surface 112 side by the second drainage pipe 31 inserted into the stretchable insertion port 127. On the dirty surface 112 side of the through hole sheet 128, the adhesive tape 41 is wound around the second drainage pipe 31 from above the hole peripheral portion 128 a of the through hole sheet 128. Thereby, the drainage pipe 3 is fixed to the drape main body 11 and the through hole 129 is sealed. In the drape 1, the sealing portion 4 for sealing between the drainage pipe 3 and the drape main body 11 is formed in the through-hole 129 by the through-hole sheet 128 and the adhesive tape 41. Further, the drainage pipe 3 is fixed to the drape main body 11 by the sealing portion 4.

  The two drainage pipes 3 connected to the two drainage ports 25 on the left and right sides of the pouch body 21 are arranged on the clean surface 111 side of the drape body 11 so that the clean surface 111 becomes closer to the through hole 129 from the drainage port 25. Gradually approach. In the two through holes 129, the two drainage pipes 3 are fixed to the drape main body 11 by the two sealing portions 4, and the gap between the drainage pipe 3 and the drape main body 11 is sealed. .

  FIG. 7 is a perspective view showing the drape 1 in use. When the drape 1 is used, the drape 1 is applied to the patient with the patient's arm 91 in the recumbent position inserted into the opening 110 of the drape body 11, and the drape body 11 covers the patient. Then, the first sheet main body 121 and the pair of horizontal wing parts 123 of the first drape sheet 12 are bent at the positions of the pair of slits 126 (see FIG. 3), and the first sheet main body 121 and the horizontal wing parts 123 The portion opposite to the opening 110 of the pair of slits 126 (hereinafter referred to as “rise portion 14”) is supported in a state where it is raised upward.

  Both side portions of the first drape sheet 12 and the second drape sheet 13 hang down in parallel to the longitudinal direction of the operating table (approximately coincident with the longitudinal direction of the drape 1) on the left and right sides of the operating table. Further, both side portions of the pouch 2 also hang down together with the first drape sheet 12. At this time, the through hole 129 into which the drainage pipe 3 (see FIG. 6) is inserted is located below the drainage port 25.

  In the first drape sheet 12, the pair of slits 126 are greatly opened, and the pair of side wings 122 that have been folded open. The pair of side wing parts 122 hang down from the rising part 14 on both the left and right sides of the operating table. In the drape 1, by providing the side wings 122, the drape main body 11 is prevented from being pulled upward in the vicinity of the rising part 14 even when the rising part 14 is raised, and both the left and right sides of the operating table A large clean area can be secured.

  Subsequently, the shape retaining member 232 of the pouch 2 shown in FIG. 6 is plastically deformed to form the liquid receiving port 210. The ends of the two drainage pipes 3 (that is, the end of the second drainage pipe 31 opposite to the end connected to the first drainage pipe 24, are shown in FIG. 6). Is stored in a container such as a waste liquid tank disposed below the operating table. The liquid from the surgical site flows into the pouch 2 through the liquid receiving port 210, flows into the drainage pipe 3 through the drainage port 25, passes through the drainage pipe 3, and is stored in the container. .

  The distal end of the drainage pipe 3 may be connected to a suction port or the like for waste fluid suction provided on the floor below the operating table. When only one suction port is provided, as shown in FIG. 8, the tips of the two drainage pipes 3 are connected to the two openings 52 of the connector 51 that is a Y-shaped pipe. The common drainage port 53, which is the remaining one of the openings, is connected to the suction port, whereby the liquid that has passed through the two drainage pipes 3 is sent to the suction port via the common drainage port 53. The connector 51 connectable to the distal ends of the two drainage pipes 3 may be accommodated in the tray 61 of the disposable medical device set 6 shown in FIG. Alternatively, it may be accommodated in the tray 61 as a part of the drape 1 without being connected to the drainage pipe 3.

  As described above, in the drape 1, the drain pipe 3 connected to the drain port 25 of the pouch body 21 is connected to the clean surface 111 side of the drape body 11 through the through hole 129 provided in the drape body 11. It extends to the dirty surface 112 side. Thereby, the exposure to the clean surface 111 side of the drainage pipe 3 can be reduced, and the movement of the practitioner is inhibited by the drainage pipe 3, that is, the drainage pipe 3 obstructs the operation. This can be suppressed. Further, since the drainage pipe 3 is fixed to the drape main body 11 by the sealing portion 4, even if the operator touches the drainage pipe 3 exposed on the clean surface 111 side, the drainage pipe It is possible to prevent the 3 from moving greatly and obstructing the operation. Further, the through-hole 129 is sealed by the sealing portion 4, whereby communication between the clean surface 111 and the unclean surface 112 can be prevented.

  As described above, the sealing portion 4 includes the through-hole sheet 128 and the adhesive tape 41 having elasticity. Then, the drainage pipe 3 is inserted into the stretchable insertion port 127 in a state where the hole peripheral portion 128a of the through hole sheet 128 is pushed to the dirty surface 112 side, and the adhesive tape 41 is inserted around the hole on the dirty surface 112 side. It is wound around the drainage pipe 3 from above the part 128a. In the drape 1, the structure on the clean surface 111 side of the drape 1 can be simplified by providing the sealing portion 4 with such a structure.

  In the drape 1, the through hole 129 is provided in the vicinity of the drainage port 25, so that the exposure of the drainage pipe 3 to the clean surface 111 can be further reduced. Thereby, it can further suppress that the drainage pipe 3 obstructs an operation. In the present embodiment, as described above, since the shortest distance between the through hole 129 and the drainage port 25 is 10 cm or less, the operator's hands, legs, etc. are placed on the drainage pipe 3 on the clean surface 111 side. It can suppress more that it is caught. From the viewpoint of further suppressing the surgeon's hand, leg, etc. from being caught on the drainage pipe 3, the shortest distance is preferably 5 cm or less.

  Further, as described above, the drainage pipe 3 gradually approaches the clean surface 111 as it approaches the through-hole 129 from the drainage port 25 on the clean surface 111 side of the drape main body 11, so that the drainage pipe 3 is operated. It can be further suppressed from obstructing. Furthermore, the through hole 129 is located on the side opposite to the opening 110 of the drainage port 25, and the through hole 129 is located below the drainage port 25 when the patient is covered with the drape main body 11. Thus, the liquid that has passed through the drainage port 25 flows easily to the waste liquid tank or the like without remaining in the drainage pipe 3.

  In the drape 1, the pouch body 21 is located on both sides of the opening 110 in the left-right direction, and the two drainage ports 25 of the pouch body 21 are also provided on both sides of the opening 110 in the left-right direction. The two drainage pipes 3 connected to the two drainage ports 25 extend from the clean surface 111 side of the drape main body 11 to the dirty surface 112 side via the two through holes 129. For this reason, even if the tips of the two drainage pipes 3 are connected to each other below the operating table or are accommodated in one waste liquid tank or the like, the drape body 11 is connected to the drainage pipe 3. It is prevented from being greatly involved in the lower side of the operating table, and the area of the clean surface 111 surrounding the operating table can be maintained large. Further, since the drape 1 includes the connector 51, the tips of the two drainage pipes 3 can be easily connected.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, A various change is possible.

  For example, when it is not particularly necessary to simplify the structure of the drape 1 on the clean surface 111 side, the drainage pipe 3 is in a state where the hole peripheral portion 128a of the through hole sheet 128 is pushed out to the clean surface 111 side. The adhesive tape 41 may be wound around the drainage pipe 3 from above the hole peripheral portion 128a on the clean surface 111 side by being inserted into the stretchable insertion port 127.

  The sealing portion 4 is not necessarily formed by the through-hole sheet 128 and the adhesive tape 41. For example, instead of the adhesive tape 41, a cylindrical member formed by an elastic member such as rubber is used for the through-hole. The drainage pipe 3 is fixed to the drape body 11 by being fitted to the second drainage pipe 31 from above the hole peripheral portion 128 a of the sheet 128, and between the drainage pipe 3 and the drape body 11 in the through hole 129. May be sealed.

  For example, the second drainage pipe 31 may have a bellows shape having alternately a small diameter part and a large diameter part. In this case, when the through-hole sheet 128 is not stretched, a substantially circular stretchable insertion port 127 having a diameter smaller than the small-diameter portion of the second drainage pipe 31 is formed in the through-hole sheet 128 and is stretched. The entire circumference of the edge of the insertion port 127 is in close contact with one small diameter portion of the second drainage pipe 31, so that the drainage pipe 3 is fixed to the drape main body 11, and the drainage pipe 3 is connected to the through-hole 129. The space between the drape body 11 may be sealed. In this case, the through-hole sheet 128 serves as the sealing portion 4.

  In the said embodiment, although the site | part of the drainage port 25 vicinity of the 2nd drainage pipe 31 and the 1st drainage pipe 24 are located in the clean surface 111 side of the drape main body 11, it shows, for example in FIG. Like the drape 1a, the first drainage pipe 24 extends from the clean surface 111 side of the drape main body 11 to the dirty surface 112 side through the through hole 129, and the first drainage pipe 24 and the second drainage pipe 24 are connected to the dirty surface 112 side. A drainage pipe 31 may be connected. In this case, the hole peripheral portion 128 a of the through-hole sheet 128 pushed out toward the unclean surface 112 by the first drainage pipe 24 is sandwiched between the first drainage pipe 24 and the second drainage pipe 31. . For this reason, even if the adhesive tape 41 is omitted, the drainage pipe 3 is fixed to the drape body 11 by the through-hole sheet 128, and between the drainage pipe 3 and the drape body 11 in the through-hole 129. Is sealed. In the drape 1a, by preventing the second drainage pipe 31 from being exposed to the clean surface 111, it is possible to further suppress the drainage pipe 3 from interfering with the operation.

  The connection between the drainage pipe 3 and the drainage port 25 of the pouch body 21 does not necessarily have to be made via the first drainage pipe 24 of the pouch 2, and various connection forms may be adopted. The drape main body 11 does not necessarily have to be formed by combining the first drape sheet 12 and the second drape sheet 13, even if the opening 110 is formed at the center of one sheet member. Good.

  The pouch body 21 does not necessarily have the shape described in the above embodiment, and may have various other shapes. For example, the pouch main body 21 may be two bag portions that are individually disposed on the left and right sides of the opening 110 of the drape main body 11 and each have a drainage port 25. The drape 1 can be used for various operations other than endoscopic surgery of the shoulder joint and knee joint, and one pouch in which one drainage tube 3 is connected to the drainage port 25 according to the usage mode. Only the main body 21 may be fixed near the opening 110 of the drape main body 11.

  The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
