In the following description, the folding portions 42 and 44 are also referred to as “lateral folding portion 42” and “longitudinal folding portion 44”, respectively, in order to facilitate distinction of the folding portions 42 and 44. Moreover, in order to make distinction of the drooping parts 43 and 45 easy, the drooping parts 43 and 45 are also called "horizontal drooping part 43" and "vertical drooping part 45", respectively. The longitudinal width of each longitudinal fold 44 is, for example, 40 cm to 60 cm. The height in the vertical direction of each vertical depending portion 45 is, for example, 10 cm to 20 cm.

  The two longitudinal folds 44 are adjacent to the longitudinal sides of the central portion 41 and the two lateral folds 42 in the semi-deployed state. The two vertical folds 44 are substantially rectangular in plan view. The two longitudinal folds 44 each include a first portion 441, a second portion 442, and a third portion 443. Each of the first portion 441, the second portion 442 and the third portion 443 has a substantially rectangular shape in plan view. The first portion 441 and the second portion 442 are continuous at a first fold line 471 extending in the lateral direction. The second portion 442 and the third portion 443 are continuous at a second fold line 472 extending in the lateral direction.

  The first portion 441 is also the longitudinal end of the central portion 41 and the two lateral folds 42. The second portion 442 vertically overlaps with the first portion 441 below the first portion 441. The second portion 442 is formed by folding the portion extending in the longitudinal direction from the first portion 441 (that is, the portion extending from the first portion 441 to the opposite side to the central portion 41) in the longitudinal direction by the first folding line 471. It is formed.

  The third portion 443 vertically overlaps the first portion 441 and the second portion 442 below the second portion 442. The third portion 443 is formed by folding the portion extending in the longitudinal direction from the second portion 442 in the longitudinal direction at the second folding line 472. The side end of the third portion 443 (i.e., the side end of the vertical folding portion 44) extends in the longitudinal direction from the first folding line 471. In other words, the side edge 476 extending in the lateral direction on the opposite side to the second folding line 472 of the third portion 443 is located on the opposite side in the longitudinal direction to the central portion 41 across the first folding line 471 Do. Furthermore, in other words, the first folding line 471 is located between the second folding line 472 and the side edge 476 of the third portion 443 in the longitudinal direction.

  The two vertical drooping portions 45 extend downward from the side edges 476 of the two third portions 443 (ie, the longitudinal side edges 476 of the two longitudinal folds 44) in the semi-deployed state. The longitudinal side edge 476 of the longitudinal folding portion 44 is also the upper edge of the vertical depending portion 45. The two vertical hanging portions 45 cover both side surfaces 96 in the vertical direction of the top plate 91 of the equipment stand 9. The lower end edge 451 of the vertical drooping portion 45 is located below the lower surface 94 of the top plate 91 of the equipment stand 9 or at approximately the same position as the lower surface 94 in the vertical direction. The two side surfaces 96 are entirely covered by the two vertical hanging portions 45.

  The equipment stand cover 1 in the semi-expanded state covers the upper surface 93 of the equipment stand 9. As a result, it is possible to prevent a nurse or the like in a clean state from accidentally contacting the upper surface 93 of the equipment stand 9 which is the unclean area. The semi-expanded equipment stand cover 1 covers the side surfaces 95 and 96 of the equipment stand 9. As a result, it is possible to prevent a nurse or the like in a clean state from accidentally contacting the side surfaces 95 and 96 of the instrument stand 9 which is the unclean area.

  The equipment stand 9 covered by the equipment stand cover 1 in the semi-deployed state is carried into the operating room as described above. Then, the switch 97 is operated to determine the position of the upper surface 93 of the equipment stand 9 in the vertical direction. As described above, since the switch 97 is covered by the side drooping portion 43 of the equipment stand cover 1, a nurse or the like in a clean state does not directly touch the switch 97 and becomes filthy. The switch 97 can be operated from above 43. After that, a part (that is, the side end of the side fold 42) of the third part 423 of each side fold 42 that extends in the lateral direction from the first folding line 461 is picked by a nurse etc. Pulled out in the direction. As a result, the respective lateral folds 42 are unfolded in the lateral direction.

  In the equipment stand cover 1, the two vertical folding portions 44 are the longitudinal portions of the central portion 41 and the two horizontal folding portions 42 in a state where a part of the equipment stand cover 1 is folded to form two lateral folding portions 42. It is formed by folding a portion including both ends of the direction. Thus, when the two lateral folds 42 are deployed in the lateral direction as described above, each longitudinal fold 44 is pulled by the two lateral folds 42 in the lateral direction. As a result, each longitudinal fold 44 is deployed in the longitudinal direction naturally (that is, without the nurse pinching and pulling). Therefore, the longitudinal folding portion 44 can be easily deployed.

  In the equipment stand cover 1, the two transversely folded portions 42 are unfolded in the lateral direction, and the two longitudinally folded portions 44 are unfolded in the longitudinal direction, so that the unfolded state shown in FIG. It becomes. The equipment stand cover 1 in the unfolded state covers the upper surface 93 and the side of the equipment stand 9 as described above. As a result, after the vertical position of the upper surface 93 of the equipment stand 9 is determined, a wide clean area (i.e., the clean surface 11) can appear on the side of the equipment stand 9. As described above, since the medical device on the equipment stand 9 is mainly placed on the central portion 41 of the medical cover 1 in the semi-expanded state, the horizontal folding portion 42 and the vertical folding portion 44 can be When deployed, there is almost no misalignment of the medical device.

  As described above, the equipment stand cover 1 is placed on the upper surface 93 of the equipment stand 9 in the folded initial state, expanded to the unfolded state, and covers the upper surface 93 and the side of the equipment stand 9 . At the time of preparation of a medical treatment, the equipment stand cover 1 covers the upper surface 93 of the equipment stand 9 in the semi-expanded state on the way which transfers to an expansion state from an initial state. The equipment stand cover 1 includes a central portion 41 and two folds 42 (i.e., lateral folds 42) in the semi-deployed state. The central portion 41 has a rectangular shape, and the dirty surface 12 contacts the upper surface 93 of the instrument stand 9. The two folds 42 are adjacent to both lateral sides of the central portion 41.

  As a result, it is possible to suppress that the part of the equipment stand cover 1 that covers the side of the equipment stand 9 will be in a dirty state at the preparation stage of the equipment stand 9. As a result, it is possible to prevent a nurse or the like from touching the part of the equipment stand cover 1 that has become unclean. In addition, it is possible to prevent the site of the instrument table cover 1 from becoming dirty, from approaching the clean area in the operating room.

  As described above, since the equipment stand cover 1 can make the wide clean area appear for the first time on the side of the equipment stand 9 when the folding unit 42 is expanded, the vertical position of the upper surface 93 can be changed. It is particularly suitable for covering a liftable equipment stand 9.

  As described above, each of the two folds 42 includes the first portion 421, the second portion 422, and the third portion 423. The first portion 421 extends laterally from the central portion 41. The second portion 422 is folded at the lower side of the first portion 421 by folding the portion extending in the lateral direction from the first portion 421 while making the unclean surfaces 12 face each other at the first fold line 461 extending in the vertical direction. 1 Overlap with the site 421. The third portion 423 is folded at the lower side of the second portion 422 by folding the portion extending in the lateral direction from the second portion 422 with the clean surface 11 facing each other by the second fold line 462 extending in the vertical direction. It overlaps with the two sites 422.

  When the folding unit 42 is expanded and the equipment stand cover 1 is in the unfolded state, the nurse or the like picks up a part of the third part 423 covered by the second part 422, and the other parts of the folding unit 42 As compared with the case of picking up the part of (1), it is possible to carry out the deployment work of the equipment table cover 1 in a cleaner state.

When the folding section 42 is expanded and the equipment stand cover 1 is in the unfolded state, a nurse or the like picks a portion of the third section 423 extending from the first folding line 461, As compared with the case where other parts are picked up, it is possible to easily carry out the deployment work of the equipment stand cover 1.

  In a state in which the equipment stand cover 1 covers the upper surface 93 of the equipment stand 9 in a semi-expanded state, only the unclean surface 12 of the equipment stand cover 1 contacts the upper surface 93 of the equipment stand 9. Thereby, the clean surface 11 of the equipment stand cover 1 can be prevented from coming into contact with the equipment stand 9 in a non-clean state.

  The equipment stand cover 1 further includes two hanging parts 43 extending downward from the lateral side edges 466 of the two folding parts 42 in the semi-deployed state. Thereby, the side surface 95 of the top plate 91 of the equipment stand 9 can be covered. As a result, it is possible to prevent a nurse or the like from touching the side surface 95 in the lateral direction of the top plate 91 of the uncleaned device stand 9. Further, the lower end edge 431 of the hanging portion 43 is located below the lower surface 94 of the top plate 91 of the equipment stand 9 or at approximately the same position as the lower surface 94 in the vertical direction. Therefore, the side surface 95 in the lateral direction of the top plate 91 can be covered by the equipment stand cover 1 over the entire surface. As a result, it is possible to prevent a nurse or the like from touching the side surface 95 in the lateral direction of the top plate 91 of the uncleaned device stand 9.

  As described above, the adhesion portion 49 adhering to the upper surface 93 of the equipment stand 9 is provided on the dirty surface 12 of the central portion 41 of the equipment stand cover 1 in the semi-expanded state. Thereby, the shift | offset | difference of the equipment stand cover 1 of the semi-expanded state which covers the equipment stand 9 can be prevented. Further, when the equipment stand cover 1 is expanded from the semi-expansion state to the unfolded state, there is no concern that the equipment stand cover 1 may slip off the equipment stand 9, so the equipment stand cover 1 can be easily expanded.

  The equipment stand cover 1 in the initial state shown in FIG. 1 is formed by being folded from the above-mentioned unfolded state through the half unfolded state and the initial unfolded state. When folded from the semi-deployed state to the initial deployed state, as shown in FIG. 7, the lateral drooping lower portion 43 causes the unclean surfaces 12 to face each other at the upper end edge (ie, the side edge 466 of the folding portion 42). While being folded in the lateral direction, the third portion 423 overlaps the third portion 423 below the third portion 423 of the folding unit 42. Then, from the state shown in FIG. 7, the portions (folded portion 42 and hanging portion 43) on both sides in the lateral direction of the equipment stand cover 1 are folded back in the lateral direction onto the central portion 41 with the clean surfaces 11 facing each other. . Thereby, the equipment stand cover 1 will be in the initial expansion state shown in FIG.

  Next, another preferable example of the structure of the folding portion will be described. FIG. 8 is a view showing a cross section perpendicular to the longitudinal direction of the equipment stand cover 1 in the semi-expanded state provided with the two folds 42a, and corresponds to FIG. In FIG. 8, the cross section of the equipment stand 9 is also shown collectively. The same applies to FIG. 9 described later. Although FIGS. 8 and 9 describe the folds corresponding to the transverse folds 42 described above, these structures may be applied to the longitudinal folds 44 described above.

  As shown in FIG. 8, the two folds 42 a further include a fourth portion 424 and a fifth portion 425 in addition to the first portion 421, the second portion 422 and the third portion 423 described above. The fourth portion 424 and the fifth portion 425 are each substantially rectangular in plan view. The fourth portion 424 is continuous with the third portion 423 at a third fold line 463 extending in the longitudinal direction. The fourth portion 424 and the fifth portion 425 are continuous at a fourth fold line 464 extending in the longitudinal direction.

  The fourth portion 424 vertically overlaps with the first portion 421, the second portion 422, and the third portion 423 below the third portion 423. The fourth portion 424 is a portion extending laterally from the third portion 423 (that is, a part of the equipment stand cover 1 extending from the third portion 423 to the opposite side to the second portion 422) to the third folding line 463 It is formed by folding back in the lateral direction while making the unclean surfaces 12 face each other.

  The fifth portion 425 vertically overlaps the first portion 421, the second portion 422, the third portion 423, and the fourth portion 424 below the fourth portion 424. The fifth portion 425 is a portion extending laterally from the fourth portion 424 (that is, a part of the equipment stand cover 1 extending from the fourth portion 424 to the opposite side to the third portion 423) to the fourth folding line 464 It is formed by turning back in the lateral direction while making the clean surfaces 11 face each other. From the longitudinally extending side edge 466 of the fifth portion 425 (i.e., the side edge 466 of the folding portion 42a), the hanging portion 43 extends downward.

  In the example shown in FIG. 8, the nurse etc. pinch the third portion 423 and the fourth portion 424 across the third folding line 463 when the folding portion 42 a is expanded and the equipment stand cover 1 is in the expanded state. As a result, the deployment work of the equipment stand cover 1 can be easily performed.

  As shown in FIG. 8, the side end of the folding portion 42 a extends in the lateral direction from the first folding line 461. Thereby, a nurse or the like can pick the third portion 423 and the fourth portion 424 more easily with the third folding line 463 interposed therebetween. As a result, the operation of deploying the equipment stand cover 1 can be performed more easily.

  Further, in a state in which the equipment stand cover 1 covers the upper surface 93 of the equipment stand 9 in a semi-expanded state, only the unclean surface 12 of the equipment stand cover 1 contacts the upper surface 93 of the equipment stand 9. Thereby, the clean surface 11 of the equipment stand cover 1 can be prevented from coming into contact with the equipment stand 9 in a non-clean state.

  Furthermore, in the folding part 42a, the equipment stand cover 1 is stacked in five layers, so that the width of the folding part 42a in the semi-expanded state is suppressed while the width of the folding part 42a in the unfolded state is reduced. The area of the side covering area can be increased.

  In the example shown in FIG. 8, the second folding line 462 vertically overlaps the fourth folding line 464. In addition, the third folding line 463 overlaps the side edge 466 of the fifth portion 425 in the top-bottom direction. The second folding line 462 may be located between the fourth folding line 464 and the first folding line 461. Alternatively, the fourth fold line 464 may be located between the second fold line 462 and the first fold line 461. In addition, the third folding line 463 may be located between the first folding line 461 and the side edge 466, and may overlap the first folding line 461 in the vertical direction. Also, the side edge 466 may also overlap with the first folding line 461 and the third folding line 463 in the top-bottom direction.

  FIG. 9 is a view showing a cross section perpendicular to the longitudinal direction of the equipment stand cover 1 in the semi-expanded state including the two folds 42b, and corresponds to FIG. As shown in FIG. 9, each of the two folds 42b includes a first portion 421a, a second portion 422a, and a third portion 423a. Each of the first portion 421a, the second portion 422a, and the third portion 423a has a substantially rectangular shape in a plan view. The first portion 421a and the second portion 422a are continuous at a first fold line 461a extending in the longitudinal direction. The second portion 422a and the third portion 423a are continuous at a second fold line 462a extending in the longitudinal direction.

  The first portion 421 a extends laterally from the central portion 41. The second portion 422a overlaps the first portion 421a in the top-bottom direction above the first portion 421a. The second portion 422a is a portion extending laterally from the first portion 421a (that is, a part of the equipment stand cover 1 extending from the first portion 421a to the opposite side to the central portion 41) by the first folding line 461a. It is formed by turning back in the lateral direction while making the clean surfaces 11 face each other.

  The third portion 423a vertically overlaps the first portion 421a and the second portion 422a above the second portion 422a. The third portion 423a is a portion extending laterally from the second portion 422a (that is, a part of the equipment stand cover 1 extending from the second portion 422a to the opposite side to the first portion 421a) to the second folding line 462a. It is formed by folding back in the lateral direction while making the unclean surfaces 12 face each other.

  Thus, similarly to the above, it is possible to suppress that the part of the equipment stand cover 1 that covers the side of the equipment stand 9 will be in a dirty state at the preparation stage of the equipment stand 9. In addition, when the folding unit 42b is expanded and the equipment stand cover 1 is in the unfolded state, a nurse or the like easily picks up the third portion 423a located above the first portion 421a and the second portion 422a. be able to. As a result, it is possible to easily carry out the deployment work of the equipment stand cover 1.

  In the example shown in FIG. 9, the drooping portion 43 extends downward from the side edge 466a of the third portion 423a (that is, the side edge 466a of the folded portion 42b). The side edge 466a of the third portion 423a vertically overlaps the first folding line 461a. The first fold line 461a may be located between the side edge 466a of the third portion 423a and the second fold line 462a.

  Various changes can be made to the equipment stand cover 1 described above.

  In the medical cover 1 shown in FIGS. 5, 8 and 9, for example, the clean surface 11 of the third portion 423 of the folding unit 42 may be provided with a tab picked up by a nurse or the like. For example, one end of a band-shaped non-woven fabric is joined to the clean surface 11 of the third portion 423 as the tab. When the folding portion 42 is deployed, the folding portion 42 can be easily deployed by a nurse or the like pinching and pulling the tab. In the medical cover 1 shown in FIG. 8, the tab may be provided on the clean surface 11 of the fourth portion 424 or the fifth portion 425 of the folding portion 42. In this case, the free end of the tab preferably projects laterally from the third fold line 463.

  For example, the clean surface 11 of the folding portion 42 or the hanging portion 43 may be provided with a mark indicating the location of the switch 97 of the device table 9 covered by the device table cover 1.

  In the equipment stand cover 1, the widths and heights of the central portion 41, the folding portions 42, 42a and 42b, the hanging portion 43, the vertical folding portion 44, and the vertical hanging portion 45 may be appropriately changed. For example, the hanging portion 43 may have a height that covers only the upper portion of the side surface 95 of the top plate 91 of the device table 9. The same applies to the vertical drop 45. In the equipment stand cover 1, the vertical folding portion 44 and the vertical hanging lower portion 45 may be omitted according to the shape of the equipment stand 9. Also, the hanging portion 43 may be omitted.

  The initial state and the initial expanded state of the equipment stand cover 1 are not limited to those shown in FIGS. 1 and 2, and various folding structures may be adopted.

  The equipment stand cover 1 may be used to cover the equipment stand 9 other than the lifting type. In addition, the equipment stand cover 1 may be used to cover a device called a name other than the equipment stand, as long as the equipment stand cover 1 corresponds to the equipment stand on which the medical equipment is placed during the medical treatment.

  The configurations in the above embodiment and each modification may be combined as appropriate as long as no contradiction arises.
