FIG. 1 is a perspective view showing a medical cover 1 according to a first related art of the present invention. The medical cover 1 is in the form of a bag having an opening 11 at the upper side in FIG. During the medical procedure, an object that is either a medical instrument or a patient's limb is inserted from the opening 11 of the medical hippo-1 so that the medical subject cover the object. . The medical hippo-1 is sterilized in advance. In the following description, it is assumed that the object is the Mayo platform which is one of medical instruments.

  The medical cover 1 includes sheet members 14 stacked in two layers each having a substantially rectangular shape. In the medical cover 1, the portions of the two layers of the sheet member 14 excluding the edge 111 of the opening 11 are bonded to each other over substantially the entire length, or are continuous with each other. In the state shown in FIG. 1, the medical cover 1 is substantially in the shape of a long band in the vertical direction in FIG. 1. An opening 11 is provided at one end of the medical cover 1 in the longitudinal direction (that is, the vertical direction in FIG. 1), and the other end is a bottom 12. A substantially rectangular reinforcing member 13 is provided in the vicinity of the bottom portion 12 of one sheet member 14 of the medical cover 1. The width of the reinforcing member 13 in the width direction perpendicular to the longitudinal direction is, for example, approximately equal to the width of the sheet member 14. The length and width of the medical cover 1 are, for example, about 1400 mm and 600 mm.

  The medical cover 1 is formed of a sheet or non-woven fabric made of a resin such as polyethylene (PE) or polypropylene (PP). In the medical cover 1, for example, the sheet member 14 is formed of a transparent polyethylene sheet, and the reinforcing member 13 formed of a non-woven fabric is joined to the outer surface of one sheet member 14. The material, shape, color and the like of the sheet member 14 and the reinforcing member 13 may be changed as appropriate.

  FIG. 2 is a perspective view showing the medical cover 1 mounted on the Mayo table 9. The Mayo stand 9 has a stage 91 on which medical instruments and the like are placed, a post 92 extending downward from one end of the stage 91, and a lower end of the post 92 protruding in substantially the same direction as the stage 91. And a leg 93 for supporting the stage 91. When the Mayo table 9 is covered with the medical cover 1, the end of the stage 91 opposite to the support 92 is inserted from the opening 11 of the medical cover 1. Then, the opening 11 is moved from the periphery of the stage 91 to the periphery of the lower portion of the support 92. As shown in FIG. 2, the stage 91 is located inside a portion near the bottom 12 of the medical cover 1. The reinforcing member 13 is disposed above the stage 91, and the upper surface of the stage 91 is covered by the reinforcing member 13. In FIG. 2, the reinforcing members 13 are diagonally hatched to facilitate understanding of the drawing.

  FIG. 3 is a perspective view showing the medical cover 1 in a state before the Mayo table 9 (see FIG. 2) is inserted. FIG. 4 is a longitudinal sectional view of the medical cover 1 shown in FIG. FIG. 4 shows a cross section at the central portion in the width direction of the medical cover 1. As shown in FIG. As shown in FIGS. 3 and 4, the medical cover 1 before use is folded back in the longitudinal direction (that is, in the vertical direction in FIGS. 3 and 4) to be compact. In the example shown in FIG. 3 and FIG. 4, the medical cover 1 has an annular first folding line 21 which is an upper folding line in the figure and an annular second folding line which is a lower folding line in the figure. A foldback line 22 is folded back.

  In the following description, a portion of the medical cover 1 from the bag-like bottom 12 to the first folding line 21 is referred to as "first portion 31" and extends from the first folding line 21 to the edge 111 of the opening 11. The site is called "second site 32". As shown in FIG. 2, in a state in which the medical cover 1 covers the mayo table 9, the second portion 32 is a cylindrical portion that extends from the first portion 31 to the opening 11. Further, the above-described reinforcing member 13 for improving the strength of the first portion 31 is joined to the first portion 31 including the bottom portion 12. In the following description, the inner surface (that is, the surface facing the Mayo table 9) of the medical cover 1 in the state covering the Mayo table 9 is referred to as the "inner surface 41", and the outer surface is the "outer surface 42". Call it The outer surface 42 of the medical cover 1 is a clean surface not in contact with the Mayo table 9. The terms inner surface 41 and outer surface 42 of the medical cover-1 refer to the direction of the surface of the medical cover -1 in the longitudinally folded state as shown in FIGS. 3 and 4 (ie, inward or outward). Orientation) is irrelevant.

  As shown in FIGS. 3 and 4, in the medical hippo-1 before insertion of the Mayo table 9, at least a portion of the second portion 32 in the vicinity of the boundary with the first portion 31 is the annular first The outer surface 42 is folded back to the outside of the first portion 31 while the outer surfaces 42 are opposed to each other by the 1 folding line 21. In addition, the second portion 32 includes an outer turn-back portion 33 that is turned outward while the inner surfaces 41 are opposed to each other by the annular second turn-around line 22. The second folding line 22 is a bottom side edge which is an end of the second portion 32 opposite to the first folding line 21. In the example shown in FIG. 3 and FIG. 4, the edge of the outer turnback portion 33 opposite to the second turnback line 22 is the edge 111 of the opening 11, and the edge 111 is the second turnback line 22 and the first turnback. Located between line 21.

  The tip of the first portion 31 (i.e., the tip of the bottom 12) protrudes downward (i.e., in the longitudinal direction) from the second folding line 22 in the figure. The protruding length of the first portion 31 in the longitudinal direction, that is, the distance in the longitudinal direction between the tip of the first portion 31 and the second folding line 22 is, for example, 3 cm or more and 20 cm or less (more preferably 5 cm or more and 10 cm) The following is. By the protrusion length of the first portion 31 being 3 cm or more, it becomes easy to recognize that the tip portion of the first portion 31 protrudes from the second folding line 22, and by the protrusion length being 5 cm or more The protrusion of the first portion 31 is more easily recognized. Moreover, when the projection length of the first portion 31 is 20 cm or less, the medical cover 1 in the folded-back state can be prevented from becoming large, and by the projection length being 10 cm or less, The increase in size of the medical hippo-1 can be further suppressed. Furthermore, since the protrusion length of the first portion 31 is 20 cm or less (more preferably, 10 cm or less), as shown in FIG. 5, when the medical cover 1 is held, the first portion 31 is It is also possible to suppress the protrusion of the drooping.

  As shown in FIG. 3, a mark 15 is provided in an area (hereinafter referred to as “exposed area 34”) of the first part 31 which is exposed from the second part 32 before the insertion of the Mayo platform 9. The mark 15 indicates the insertion position of the hand for the nurse or the like to hold the medical hippo 1 folded back in the longitudinal direction. In the example shown in FIG. 3, in the exposed region 34 of the first portion 31, two marks 15 are provided in the vicinity of both end portions in the width direction. The mark 15 is provided on the front exposed region 34 in FIG. 3, that is, on the sheet member 14 (see FIG. 1) provided with the reinforcing member 13 in the first portion 31. The two marks 15 are arranged, for example, on the reinforcing member 13.

  As the mark 15, for example, an illustration of a hand or the like, a symbol such as an arrow, characters, patterns, and a combination thereof are used. In the example shown in FIG. 3, the combination of the hand illustration and the arrow is used as each mark 15, and the direction of the hand of the illustration and the direction of the arrow indicate the insertion direction of the nurse's hand. . For example, a sheet piece on which an arrow or the like is printed may be attached to the exposed area 34 of the first portion 31 as the mark 15. In this case, the color of the sheet piece is preferably different from the color of the exposed area 34. In addition, the mark 15 may be printed on the exposed area 34 by inkjet printing or the like.

  When the medical cover 1 is attached to the Mayo table 9, for example, as shown in FIG. 3, the medical cover 1 in a folded state is placed with the mark 15 and the reinforcing member 13 facing upward. Ru. Then, a nurse or the like in a clean state inserts both hands between the upper first portion 31 and the second portion 32 as shown in FIG. With the cover extended to the front, lift the medical cover. The nurse's hands support the upper second portion 32 from below. The nurse's hands contact the outer surface 42 (i.e., the clean surface) of the upper first portion 31 and the second portion 32. The upper first portion 31 means one of the two portions (i.e., two layers of sheet members 14) opposite to each other in the first portion 31 that is located on the upper side in the direction of gravity. The upper second portion 32 is one of the two portions facing each other with the first portion 31 of the second portion 32 (ie, the sheet member 14 of two layers) positioned on the upper side in the gravity direction means.

  The lower second portion 32 and the first portion 31 are spaced downward from the upper first portion 31 and the second portion 32 depending on their weights. Thereby, the first folding line 21 annularly spreads in front of the nurse's hands, and the first portion 31 naturally opens forward. In this state, the tip of the stage 91 (see FIG. 2) of the Mayo table 9 is inserted inside the first portion 31 and both hands of the nurse are moved along the Mayo table 9 to make the stage 91 for medical use. It is located inside the hippo-1. At this time, the nurse's hands are in contact only with the outer surface 42 of the medical hippo-1 without being in contact with the Mayo table 9 or the inner surface 41 of the medical hippo-1. This maintains the cleanliness of the nurse. Thereafter, another nurse or the like in the unclean state holds the outer turn-back portion 33 of the second portion 32 and moves it downward along the pillars 92 of the Mayo table 9, whereby the medical cover 1 is a pillar 92. Will be stretched along. Thereby, the Mayo stand 9 is covered by the medical hippo-1.

  As described above, in the medical cover 1, at least the portion of the second portion 32 near the first folding line 21 before the insertion of the Mayo table 9 is the outer surface 42 at the annular first folding line 21. It is folded back to the outside of the first portion 31 while facing each other. Further, the tip end portion of the first portion 31 protrudes from the second turn-up line 22 which is an end edge of the second portion 32 opposite to the first turn-up line 21.

  Thereby, the medical cover 1 before insertion of Mayo stand 9 can be made compact. Further, as described above, when the nurse inserts both hands between the upper first portion 31 and the second portion 32, the outer surface of the medical cover 1 which becomes a clean surface after being attached to the Mayo table 9 While touching only 42, the medical cover 1 can be easily held, and the Mayo table 9 can be easily inserted into the medical cover 1.

  By the way, assuming that the tip of the first portion 31 does not protrude from the end of the second portion 32 opposite to the first folding line 21 in the medical cover 1 before insertion of the Mayo table 9, nursing When the operator inserts his hand into the medical cover 1, the operator can not easily recognize the insertion position, and erroneously inserts the hand between the lower first portion 31 and the second portion 32. There is a possibility of Alternatively, there is a possibility that a hand may be inserted between the upper first portion 31 and the lower first portion 31 from the side of the first folding line 21. In this case, since the first portion 31 does not naturally open at the first folding line 21, the insertion of the Mayo base into the medical hippo-1 becomes difficult.

  On the other hand, in the medical cover 1 shown in FIG. 3, as described above, the tip of the first portion 31 protrudes from the second folding line 22 of the second portion 32. The boundary between the upper first portion 31 and the second portion 32 (that is, the second folding line 22), which is the insertion position, can be easily recognized. Thereby, as shown in FIG. 5, both hands of the nurse can be easily inserted between the upper first portion 31 and the second portion 32. As a result, the Mayo table 9 can be easily inserted into the medical hippo 1, and the medical hippo 1 can be easily attached to the Mayo table 9.

  In the medical cover 1 before insertion of the Mayo table 9, the second portion 32 includes an outer turn-back portion 33 which is turned outward while the inner surfaces 41 are opposed to each other at the second turn-around line 22. As a result, after the Mayo table 9 is inserted into the medical hippo 1 to a certain extent, when the medical hippo 1 is extended (that is, pulled down) by the unclean nurse or the like, the nurse is medical A portion in the vicinity of the opening 11 of the cover 1 can be easily grasped. Further, in the medical cover 1 before insertion of the Mayo table 9, the edge 111 which is the end edge of the outer folded portion 33 opposite to the second folded line 22 is the second folded line 22 and the first folded line 21. Located between As a result, it is possible to reduce the area touched by the unclean nurse who stretches the medical hippo 1, that is, the outer turn-back portion 33 which is the unclean permission area.

  As described above, in the medical cover -1, the hand for holding the medical cover -1 in the exposed area 34 of the first part 31 exposed from the second part 32 before the insertion of the Mayo table 9 is performed. A mark 15 is provided to indicate the insertion position. Thereby, a nurse or the like in a clean state holding the medical cover 1 can more easily recognize the position where the hand is inserted. Further, the medical cover 1 is provided with a reinforcing member 13 which is joined to the first portion 31 to improve the strength of the first portion 31. Thereby, it can suppress that the 1st part 31 which covers the stage 91 which is the principal part of the Mayo stand 9 is damaged.

FIG. 6 is a perspective view showing a state before insertion of the Mayo table 9 (see FIG. 2) of a medical hippo according to a second related art of the present invention. FIG. 7 is a longitudinal cross-sectional view of the medical cover 1a shown in FIG. FIG. 7 shows a cross section at the central part in the width direction of the medical cover 1a. In the medical hippo 1a, before the insertion of the Mayo table 9, a portion in the vicinity of the edge 111 which is an end edge opposite to the second folding line 22 of the outer folding portion 33 is from the first folding line 21 in the figure. Project upward (ie, longitudinally). In other words, in the medical cover 1a before insertion of the Mayo table 9, the edge 111 is located at a position farther from the second folding line 22 than the first folding line 21 in the longitudinal direction. The other configuration of the medical cover 1a is approximately the same as that of the medical cover 1 shown in FIGS. 1 to 4, and in the following description, the corresponding components are denoted by the same reference numerals.

  In the medical cover 1a shown in FIGS. 6 and 7, as with the medical cover 1 shown in FIGS. 3 and 4, at least the first folding line 21 of the second portion 32 before the insertion of the Mayo table 9. The nearby portion is folded back to the outside of the first portion 31 while making the outer surfaces 42 face each other at the annular first fold line 21. Further, the tip end portion of the first portion 31 protrudes from the second turn-up line 22 which is an end edge of the second portion 32 opposite to the first turn-up line 21.

  Thereby, the medical cover 1a before insertion of Mayo stand 9 can be made compact. In addition, a clean nurse or the like inserts the hands between the first portion 31 and the second portion 32 on the upper side (that is, the front side in FIG. While touching only the outer surface 42 of the medical cover 1a which becomes the medical treatment cover 1a, the medical cover 1a can be easily held, and the Mayo base 9 can be easily inserted into the medical cover 1a. Furthermore, the nurse easily recognizes the boundary between the upper first portion 31 and the second portion 32 (that is, the second folding line 22), which is the insertion position of the hand, and the upper first portion 31 and the first portion 31 Both hands can be easily inserted between the two parts 32. As a result, it is possible to easily attach the medical hippo 1a to the Mayo table 9.

  In the medical cover 1a before insertion of the Mayo table 9, the second portion 32 includes an outer turn-back portion 33 which is turned back while the inner surfaces 41 are opposed to each other by the second turn-around line 22. As a result, after the Mayo table 9 is inserted into the medical hippo 1a to a certain extent, when the medical hippo 1a is extended (that is, pulled down) by the unclean nurse or the like, the nurse is medical A portion in the vicinity of the opening 11 of the cover 1a can be easily grasped.

  As described above, in the medical cover 1a before the insertion of the Mayo table 9, the portion in the vicinity of the edge 111, which is the end edge opposite to the second folding line 22 of the outer folding portion 33, is the first folding line 21. Project from the Thereby, when a nurse or the like in a clean state holds the medical cover 1a, the possibility of inserting a hand between the upper side and the lower side first portion 31 from the opening 11 and the first folding line 21 side Thus, the nurse can more easily insert both hands between the upper first portion 31 and the second portion 32. In addition, since the outside turn-back portion 33 is relatively large, a nurse or the like in an unclean state extending the medical cover 1a can grip the part near the opening 11 of the medical cover 1a more easily. . Furthermore, since the edge 111 is relatively far from the tip end of the first portion 31, the portion gripped by a nurse or the like in the unclean state is relatively large from the outer surface 42 of the bottom portion 12 of the first portion 31 which is a clean area. It can be released. As a result, maintenance of the cleanliness of the bottom 12 of the first portion 31 can be facilitated.

  In the medical hippo 1a, a mark indicating the insertion position of a hand for holding the medical hippo 1a in the exposed area 34 of the first part 31 exposed from the second part 32 before the insertion of the Mayo platform 9 15 are provided. Thereby, a nurse or the like in a clean state holding the medical cover 1a can more easily recognize the position where the hand is inserted. Further, the medical cover 1a includes the reinforcing member 13 joined to the first portion 31 to improve the strength of the first portion 31. Thereby, it can suppress that the 1st part 31 which covers the stage 91 (refer FIG. 2) which is the principal part of the Mayo stand 9 is damaged.

8, the medical cover -1b according to an embodiment of the present invention, is a perspective view showing a state before insertion of the Mayo stand 9 (see FIG. 2). FIG. 9 is a longitudinal sectional view of the medical cover 1b shown in FIG. FIG. 9 shows a cross section at the central part in the width direction of the medical cover 1b. In the medical hippo 1b, the shape of the second portion 32 before the insertion of the Mayo table 9 is different from that of the medical hippo 1 shown in FIGS. 3 and 4. The other configuration of the medical cover 1b is approximately the same as that of the medical cover 1 shown in FIGS. 1 to 4, and in the following description, the corresponding components are denoted by the same reference numerals.

  In the medical cover 1b shown in FIGS. 8 and 9, the second portion 32 before the insertion of the Mayo table 9 includes the first stacked portion 35, the second stacked portion 36, the third stacked portion 37, and the outer side folding. And 33. The first stacked portion 35 is a portion of the second portion 32 in the vicinity of the first folding line 21 which is a boundary with the first portion 31. The first stacked portion 35 is folded back to the outside of the first portion 31 at the first fold line 21. The second stacked portion 36 is folded back to the inside of the first stacked portion 35 while making the outer surfaces 42 face each other at a first intermediate folding line 25 which is a boundary between the second stacked portion 35 and the first stacked portion 35. The first intermediate folding line 25 includes the first folding line 21 and the second folding line 22 in the longitudinal direction (that is, the bottom side edge which is the end of the second portion 32 opposite to the first folding line 21) Located between

  The third stacked portion 37 is folded back inside the second stacked portion 36 while the inner surfaces 41 are opposed to each other at a second intermediate folding line 26 which is a boundary between the third stacked portion 36 and the second stacked portion 36. The second intermediate folding line 26 is located between the first intermediate folding line 25 and the first folding line 21 in the longitudinal direction. The outer turn-back portion 33 is configured such that the third stack portion 37, the second stack portion 36, and the first stack portion 35 make the inner surfaces 41 face each other at the second fold line 22 which is a boundary between the third stack portion 37 and the third fold portion 37. Is folded outside of The second folding line 22 is a bottom side edge which is an edge opposite to the second intermediate folding line 26 of the third stacked portion 37. In the example shown in FIGS. 8 and 9, an edge 111 which is an end edge of the outer turnback portion 33 opposite to the second turnback line 22 is located between the first turnback line 21 and the second turnback line 22. . In detail, the edge 111 is located between the first folding line 21 and the first intermediate folding line 25.

  At least a portion of the third stacked unit 37 is located between the second stacked unit 36 and the first portion 31. At least a part of the third stacked unit 37 and the second stacked unit 36 are located between the first stacked unit 35 and the first portion 31. Therefore, at least a part of the outer surface 42 of the first stacked portion 35 indirectly faces the outer surface 42 of the first portion 31 with the second stacked portion 36 and the third stacked portion 37 interposed therebetween. The inner surface 41 of the outer folded portion 33 faces at least a part of the inner surface 41 of the first stacked portion 35. In the example shown in FIG. 8 and FIG. 9, since the second folding line 22 is separated from the first intermediate folding line 25 in the longitudinal direction, a part of the inner surface 41 of the outer folding portion 33 is the third laminated portion 37. It also opposes part of the inner surface 41.

  As described above, in the medical cover 1b before insertion of the Mayo table 9, the second portion 32 includes the first stacked portion 35, the second stacked portion 36, and the third stacked portion 37. Thereby, the medical cover 1b before insertion of the Mayo stand 9 can be made further compact. Further, when the second portion 32 further includes the outer side folded portion 33, when a nurse or the like in a clean state holds the medical cover 1b, the second stacked portion 36 and the third stacked portion 37 are erroneously inserted. It is possible to prevent the insertion of a hand in between. This allows the nurse to more easily insert both hands between the upper first portion 31 and the second portion 32. As a result, the mounting of the medical hippo 1b on the Mayo table 9 can be made even easier.

  In the medical cover 1b shown in FIGS. 8 and 9, a portion near the edge 111 of the outer turn-back portion 33 may project from the first turn-around line 21 in the longitudinal direction before the Mayo table 9 is inserted. Thereby, similarly to the medical cover 1a shown in FIGS. 6 and 7, the nurse etc. in a clean state can more easily insert both hands between the upper first portion 31 and the second portion 32. Can. In addition, a nurse or the like in a dirty state, who stretches the medical hippo 1b, can grip the part near the opening 11 of the medical hippo 1b more easily. Furthermore, the part gripped by the unclean nurse or the like can be separated relatively largely from the outer surface 42 of the bottom 12 of the first part 31 which is the clean area. As a result, maintenance of the cleanliness of the bottom 12 of the first portion 31 can be facilitated.

  The medical cover -1, 1a, 1b can be variously modified.

  For example, the reinforcing member 13 need not necessarily be provided, and may be omitted. In this case, since the two-layered sheet members 14 described above have substantially the same structure, when the medical cover -1, 1a, 1b is held by a nurse or the like in a clean state, which sheet member 14 is the upper side It may be taken. Therefore, the above-mentioned mark 15 is preferably provided in the exposed area 34 in both of the two-layer sheet members 14. Thereby, in the placed medical cover -1, 1a, 1b, the nurse in a clean state is the upper first portion 31 even when either of the two-layer sheet members 14 is facing upward. Both hands can be inserted between the second portion 32 and the second portion 32 more easily.

  In the medical cover -1, 1a, 1b, it is not necessary to necessarily provide the cylindrical outer folded portion 33. For example, in the medical cover 1, the outer turn-back portion 33 extends from only a part of the annular bottom side end edge of the second portion 32 (that is, the end edge on the opposite side to the first turn-around line 21) The outer folds 33 may not be provided at other portions of the bottom side edge. Alternatively, the outside turn-up portion 33 may be omitted from the medical cover 1. The same applies to the medical hippoes 1a and 1b.
