Summary of the Invention

Problems to be Solved by the Invention

[0007] However, since the above-described conventional cover (stretcher isolator) is mainly used from the perspective of privacy protection for the person being transported, there is a drawback that it does not necessarily function effectively as a measure against infection by viruses and the like.

[0008] On the one hand, when transporting patients or the elderly in hospitals, elderly care facilities, etc., in the case of a person to be transported (user) lying on a stretcher, it is possible to use a conventional isolator. However, in the case of a person to be transported moving in a wheelchair, there has been a problem that it is physically difficult to use. This problem exists for ordinary people who use wheelchairs due to disabilities in their legs, and even for ordinary people sitting on ordinary chairs, etc. For this reason, there has been a long-standing desire to put into practical use a suitable isolator that can be used by such seated people.

[0009] In addition, in the case of a user lying down, since the isolator is also horizontally long, it is possible to easily create an opening for communicating the inside and the outside by simply lifting one side slightly. However, in the case of a seated user, it is not easy to provide such a communication space, and in the case of a wheelchair, the user may operate the wheels by themselves. In addition, portability that allows it to be carried anywhere is also an important factor. The fact is that no suitable isolator for seated users has been proposed.

[0010] An object of the present invention is to provide a seating isolator that solves the problems existing in such background art.

Means for Solving the Problems

[0011] In order to solve the above-described problems, the present invention provides a seating isolator 1 that shields a seated user H. The isolator 1 is configured in a loop shape by a wire W made of a highly elastic stainless steel material that is an elastic material, and has at least a left frame member 2p, a right frame member 2q, and an intermediate frame member 2m located in front or behind. Each wire W... is covered by a covering portion 3..., and the covering portions 3... in each frame member 2p, 2q, 2m are sequentially connected to form a frame portion F having an overall vertically long rectangular parallelepiped shape. By twisting two locations K1, K2 in the longitudinal direction of the stacked frame members 2m, 2q, 2p by 180°, they can be stacked in three circular shapes. The lower surface portion 4d is opened, and the remaining surface portions 4p, 4q, 4m, 4r, 4u are closed by a flexible transparent sheet material Sm... to form a sheet cover portion 4, thereby forming an isolator main body portion Um. An isolator window portion Up, Uq is provided, which has openings 5p, 5q provided at predetermined positions of the sheet material Sm... of the left surface portion 4p surrounded by the left frame member 2p and / or the sheet material Sm of the right surface portion 4q surrounded by the right frame member 2q, shields the openings 5p, 5q, and is formed by a second sheet material Ss... provided with entrances and exits 6p, 6q, and has diameter changing portions 8p, 8q capable of changing the sizes of the entrances and exits 6p, 6q.

[0012] In this case, according to a preferred embodiment of the invention, a wire rod W with a rectangular cross-section can be used. Further, the isolator main body Um can be provided with a sub-cover portion 11 formed in a cylindrical shape by a third sheet material St on the lower surface portion 4d of the sheet cover portion 4 and hanging down to a predetermined length, and at least a part of the lower portion 11d of the sub-cover portion 11 can be provided with an elastic expansion and contraction portion 12 along the circumferential direction Df. On the other hand, the isolator main body Um can be provided with a regulation function portion 13 having a pair of left and right pole mounting portions 13p and 13q respectively attached to the covering portions 3 of the left frame member 2p and the right frame member 2q, and a pole portion 13s that is detachably disposed between the pole mounting portions 13p and 13q to regulate the interval between the left frame member 2p and the right frame member 2q. Further, a fastener portion 15 that can be opened and closed left and right can be provided on the sheet cover portion 4 and the sub-cover portion 11 on the surface portion (rear surface portion 4r) facing the intermediate frame member 2m (front surface portion 4m) of the isolator main body Um.

Advantages of the Invention

[0013] According to the seating isolator 1 according to the present invention having such a configuration, the following remarkable effects can be obtained.

[0014] (1) Even for a user H moving in a wheelchair or the like while in a seated state, it is possible to shield substantially the entire upper body required for the user H and obtain an internal space with little sense of compression. As a result, it is possible to provide an isolator that is optimal for the user H in a seated state, such as ensuring sufficient shielding performance. Moreover, when not in use, it can be folded into a compact and flat state, so it is excellent in portability and storage. When in use, if it is taken out from a bag or the like, it automatically expands into a use form by a pop-up method, so it can be quickly set on a wheelchair or the like, and it is excellent in handling.

[0015] (2) Since the isolation window portions Up and Uq can provide a communication space that connects the inside and the outside, it is possible to easily insert and remove items such as towels and thermometers, and minimize the internal and external air movement that occurs at this time. Thus, while ensuring sufficient shielding performance, it is possible to easily and quickly conduct necessary interactions between the inside and the outside. Moreover, even for wheelchair users H, the isolation window portions Up and Uq enable them to operate the wheels by themselves, enhancing functionality and convenience.

[0016] (3) As the wire material W uses a high-elastic stainless steel material, from the perspective of automatically deploying into a usage form by a pop-up method, quickly setting it, and folding it into a compact and flat state, which is the object of the present invention, it can be used as an optimal wire material W.

[0017] (4) In a preferred embodiment, when constructing the isolator main body portion Um, if a sub-cover portion 11 formed in a cylindrical shape by a third sheet material St and hanging down to a predetermined length is provided on the lower surface portion 4d of the seat cover portion 4, the opening to the outside with respect to the open lower surface portion 4d can be positioned further downward, so that the overall shielding performance can be enhanced.

[0018] (5) In a preferred embodiment, if an elastic expansion and contraction portion 12 along the circumferential direction Df is provided on at least a part of the lower portion 11d of the sub-cover portion 11, the lower portion 11d of the sub-cover portion 11 can be made to fit more closely to the user H, thus enhancing the shielding performance. Moreover, the wearing stability when wearing the isolator 1 can be further enhanced, and easy detachment due to wind or the like can be prevented.

[0019] (6) In a preferred embodiment, if a regulation function unit 13 is provided on the isolator main body Um, which has a pair of left and right pole mounting parts 13p and 13q respectively attached to the covering parts 3 of the left frame member 2p and the right frame member 2q, and a pole part 13s that is detachably mounted between the pole mounting parts 13p and 13q to regulate the distance between the left frame member 2p and the right frame member 2q, the position regulation function and reinforcement function by the pole part 13s can be added, so that the strength (rigidity) and shape stability of the isolator main body Um can be further enhanced.

[0020] (7) In a preferred embodiment, if a fastener part 15 that can be opened and closed left and right is provided on the sheet cover part 4 and the sub-cover part 11 on the facing surface (rear surface part 4r) of the isolator main body Um facing the intermediate frame member 2m (front surface part 4m), when the isolator 1 is being worn or removed by the user H, the lower side of the isolator 1 can be widened, so that the wearing operation or removal operation can be performed more easily and quickly, and problems such as the isolator 1 hitting the user H during wearing or removal can be avoided.

Best Mode for Carrying Out the Invention

[0022] Next, preferred embodiments according to the present invention will be given and described in detail with reference to the drawings.

[0023] First, the configuration of the seating isolator 1 according to the present embodiment will be specifically described with reference to FIGS. 1 to 6.

[0024] As shown in FIG. 1, the isolator 1 basically includes an isolator main body portion Um and isolator window portions Up and Uq provided in the isolator main body portion Um.

[0025] As shown in FIG. 6, the isolator main body portion Um includes a left frame member 2p, a right frame member 2q, and an intermediate frame member 2m formed in a loop shape by a wire W made of an elastic material.

[0026] For the wire W, a high-elastic stainless steel material having a rectangular cross section (exemplified as 5 [mm] × 1.5 [mm]) can be used. In this way, if a high-elastic stainless steel material is used as the wire W, from the viewpoint of automatically deploying it into a use form by a pop-up method, quickly setting it, and folding it into a compact and flat state, which is the object of the present invention, it can be used as an optimal wire W. Each of the frame members 2p, 2q, and 2m is formed in the same shape. Therefore, it is only necessary to prepare three identical frame members 2p....

[0027] Further, each wire W is covered by a covering portion 3…. As the material of the covering portion 3…, a sheet member made of synthetic fiber having excellent strength and water repellency is desirable. For example, all of the wires W… in each frame member 2p, 2q… are covered by the covering portion 3, but only a part of the wires W… may be covered, such as by providing holes at appropriate positions. As a covering method, a single sheet member may be wound around the wire W and both end sides may be sewn. Further, the covering portions 3… in each frame member 2p, 2q, 2m are sequentially connected by sewing to form a frame portion F having a vertically long rectangular parallelepiped shape as a whole.

[0028] In this case, as shown in FIG. 6, each frame member 2p, 2q, 2m has upper and lower short side portions 2ps…, 2qs…, 2ms… formed in an arc shape, and long side portions 2pl…, 2ql…, 2ml… between the short side portions 2ps…, 2qs…, 2ms… are covered by the covering portion 3… so as to be linear, and the intervals between the connected covering portions 3… are made close to each other and joined. The size of the exemplary frame member 2p… is selected such that the length in the longitudinal direction (vertical direction) is about 100 - 110 [cm], and the length in the short transverse direction is selected to be about 45 [cm].

[0029] Then, the left side surface portion 4p, the right side surface portion 4q, the front surface portion 4m, the rear surface portion 4r, and the upper surface portion 4u of the rectangular parallelepiped-shaped frame portion F are closed by a flexible transparent sheet material Sm…. The sheet material Sm… constitutes a sheet cover portion 4. Also, the lower surface portion 4d is open. In the exemplary case, a thermoplastic polyurethane (TPU) material with a thickness of 0.2 mm was used for the sheet material Sm. In this way, if all (or part) of the sheet cover portion 4 is formed of the transparent sheet material Sm, the state of the user H inside the sheet cover portion 4 can be easily and surely visually recognized from the outside. Therefore, for example, even in a case where the user's condition suddenly changes, a prompt response can be made.

[0030] When attaching the sheet cover portion 4, a sheet material Sm… corresponding to the shape of each surface portion 4p, 4q, 4m, 4r, 4u is prepared in advance, and when sewing each covering portion 3…, they can be joined by sewing them together.

[0031] On one hand, as shown in FIG. 1, at a predetermined position of the sheet material Sm in the left face portion 4p surrounded by the left frame member 2p and the right face portion 4q surrounded by the right frame member 2q, specifically, near the center, circular or elliptical isolator window portions Up and Uq having a diameter of about 1 / 3 of the total longitudinal length of each of the frame members 2p and 2q are provided.

[0032] As shown in FIG. 4, the right isolator window portion Uq includes an opening 5q provided in the sheet material Sm of the right face portion 4q surrounded by the right frame member 2q, a shielding portion 7q formed by a second sheet material Ss that covers this opening 5q and is provided with an entrance / exit 6q, and a diameter changing portion 8q capable of changing the size of the entrance / exit 6q. In this case, a ring-shaped window frame portion 21 formed of a plastic sheet or the like having the same inner diameter as the inner diameter of the opening 5q is prepared, and one end opening side of the cylindrical shielding portion 7q formed by the window frame portion 21 and the second sheet material Ss can be sewn and fixed together to the edge of the opening 5q. Also, the other end opening side of the shielding portion 7q is formed as the entrance / exit 6q, and the diameter changing portion 8q is provided at this other end opening side. The diameter changing portion 8q is formed by a tunnel-shaped bag portion 24 through which an opening / closing string 23 can pass along the edge of the other end opening side of the shielding portion 7q. The opening / closing string 23 is passed through this bag portion 24, and both end sides of the opening / closing string 23 are pulled out from both end openings of the bag portion 24 to the outside as shown in FIG. 4 to be configured. Note that 25 indicates a string stopper attached to the opening / closing string 23.

[0033] Thereby, by releasing the fixed lock of the string stopper 25, pulling out the opening / closing string 23 with respect to the bag portion 24 to narrow the entrance / exit 6p as shown by the solid line in FIG. 4, and then re-fixing and locking the string stopper 25, the entrance / exit 6p can be made smaller in diameter to be in the closed mode. Also, by releasing the fixed lock of the string stopper 25, as shown by the virtual line in FIG. 4, the entrance / exit 6p can be expanded to be in the open mode with a larger diameter. Thus, by operating the diameter changing portion 8p, the size of the entrance / exit 6p can be easily changed.

[0034] The above describes the isolator window portion Uq on the right side. However, the isolator window portion Up on the left side can also be configured in the same manner as the isolator window portion Uq on the right side. When the overall shape is asymmetric, the isolator window portion Uq on the right side and the isolator window portion Up on the left side may be configured symmetrically.

[0035] On the other hand, a sub-cover portion 11 is provided on the lower surface portion 4d of the sheet cover portion 4 in the isolator main body portion Um. In this case, as shown in FIG. 1, the upper edge of the sub-cover portion 11 formed in a cylindrical shape by the third sheet material St and hanging down to a predetermined length can be joined so as to communicate with the open lower surface portion 4d. The same material as the second sheet material Ss described above can be used for this third sheet material St. By providing such a sub-cover portion 11, the opening to the outside with respect to the open lower surface portion 4d can be positioned further downward, so that the overall shielding property can be enhanced.

[0036] Further, an elastic expansion and contraction portion 12 along the circumferential direction Df is provided in the lower portion 11d of the sub-cover portion 11. This elastic expansion and contraction portion 12 can be formed of an elastic rubber material. Although an example where it is provided along the entire circumference is shown, it may be in a partial range. By providing such an elastic expansion and contraction portion 12, the lower portion 11d of the sub-cover portion 11 can be made to fit more closely to the user H, so that the shielding property can be enhanced. Moreover, the wearing stability when wearing the isolator 1 can be further enhanced, and easy detachment due to wind or the like can be prevented.

[0037] Furthermore, as shown in FIGS. 2 and 3, a regulating function unit 13 is provided at the upper end (or in the vicinity thereof) of the isolator main body Um. This regulating function unit 13 is configured by providing a pair of pole mounting parts 13p and 13q on the left and right covering parts 3... in the upper part Umu of the isolator main body Um, and including a detachable pole part 13s between the pole mounting parts 13p and 13q. As the pole part 13s, a single pole selected to have a length substantially matching the lateral width of the intermediate frame member 2m may be used, or a telescopic pole with adjustable length may be used. Thereby, as shown in FIGS. 2 and 3, when the pole part 13s is mounted between the pole mounting parts 13p and 13q, the distance between the left frame member 2p and the right frame member 2q can be regulated by the pole part 13s. By providing such a regulating function unit 13, a position regulating function and a reinforcing function by the pole part 13s can be added, so that the strength (rigidity) and shape stability of the isolator main body Um can be further enhanced.

[0038] On the other hand, as shown in FIGS. 2 and 3, fastener parts 15 that can be opened and closed left and right are provided on the seat cover part 4 and the sub-cover part 11 of the rear surface part 4r, which is the surface part facing the front surface part 4m of the intermediate frame member 2m of the isolator main body Um. That is, at the central position in the left-right direction of the rear surface part 4r, a fastener part 15 extending from the lower end edge of the sub-cover part 11 to the front end positions of the rear surface part 4r and the upper surface part 4u. It is desirable to use a double fastener for this fastener part 15 that can be opened and closed from above and below. By providing such fastener parts 15, when the user H wears or removes the isolator 1, the lower side of the isolator 1 can be widened, so that the wearing operation or the removal operation can be performed more easily and quickly, and problems such as the isolator 1 hitting the user H during wearing or removal can be avoided.

[0039] Next, a method of using the seating isolator 1 according to the present embodiment will be described with reference to FIGS. 1 - 9.

[0040] FIG. 7 shows an example of a bag B for accommodating the isolator 1. This bag B has a lateral width Ld of 40 cm and a thickness of about 9 cm. Therefore, when not in use, the isolator 1 can be folded and accommodated in this bag B. Note that Bf indicates the bag opening of the bag B, and this bag opening Bf can be opened and closed by a fastener.

[0041] FIG. 8 shows each aspect of the isolator 1 when folded and when deployed. FIG. 8(c) shows a state in which the left frame member 2p and the right frame member 2q are each folded over 180° with respect to the intermediate frame member 2m. That is, FIG. 8(c) shows a state in which the intermediate frame member 2m is positioned at the lower end, the right frame member 2q is on top of this intermediate frame member 2m, and further, the left frame member 2p is sequentially stacked on top of this right frame member 2q, with the left frame member 2p appearing on the upper surface.

[0042] Then, when folding, if two locations K1 and K2 (positions approximately trisecting the longitudinal direction) in the longitudinal direction shown in FIG. 8(c) are twisted through 180° as shown in FIG. 8(b), three circular shapes are formed as shown in FIG. 8(b). Therefore, by overlapping while twisting, it can be folded into a flat state in which the three circular shapes shown in FIG. 8(a) overlap. The isolator 1 folded in this way can be directly accommodated in the aforementioned bag B.

[0043] Next, the procedure for using the isolator 1 in this accommodated state will be described. First, the isolator 1 is taken out from the bag B. This state is the state shown in FIG. 8(a). Then, if the taken-out isolator 1 is simply placed on the floor surface or the like, since each frame member 2p, 2q, 2m of the isolator 1 is configured in a loop shape by a wire W made of an elastic material, and each wire W is covered by a covering portion 3..., due to the elastic return action of each frame member 2p, 2q, 2m, as shown in FIG. 8(b), it automatically pops up and deploys, and finally, it reaches a state in which the three frame members 2p, 2q, 2m shown in FIG. 8(c) overlap.

[0044] From this state, the left frame member 2p at the upper end is expanded in the left perpendicular direction, and then the right frame member 2q is expanded in the right perpendicular direction. As a result, the state shown in FIG. 6 can be achieved. Then, as shown in FIG. 3, a pole portion 13s is prepared, and one end of this pole portion 13s is inserted into one pole mounting portion 13p, and the other end is inserted into the other pole mounting portion 13p. FIGS. 2 and 3 show the state in which the pole portion 13s is mounted.

[0045] As described above, since the isolator 1 can be used, the fastener portion 15 is opened and expanded over the necessary range from the sub-cover portion 11 to the rear portion 4r. The virtual lines 11s…, 4rs… shown in FIGS. 2 and 3 indicate the expanded sub-cover portion 11 and rear portion 4r. Then, the isolator 1 in this state may be mounted on the user (the person to be transported) H sitting on the seat surface Rs of the wheelchair R as shown in FIG. 9 so as to cover the user from above. When the lower end of the isolator 1 is placed on the thigh Hs of the user H due to the mounting, the mounting is completed, so the fastener portion 15 may be closed in this state. FIG. 9 shows a state in which the isolator 1 is mounted on the user (the person to be transported) H sitting on the wheelchair R, and for example, a caregiver Hu is operating the wheelchair R. In this way, the mounting of the isolator 1 on the seated user H can be performed extremely easily and quickly.

[0046] On the other hand, in this state, when an article such as a towel or a thermometer is passed from the caregiver Hu to the user H or returned from the user H to the caregiver Hu, it can be done through the isolator window portion Up (the same applies to the isolator window portion Uq side). In this case, the fixed lock of the string stopper 25 is released, and as shown in FIG. 4, the small-diameter entrance / exit 6p shown by the solid line can be expanded as shown by the virtual line to increase the diameter. Therefore, as shown in FIG. 6, the hand Hh can be inserted and passed through the enlarged entrance / exit 6p, and if necessary, the opening / closing string 23 can be pulled to constrict the entrance / exit 6p to eliminate the gap generated by the increase in diameter. Even in this state, due to the presence of the shielding portion 7p, the position of the entrance / exit 6p can be moved freely to a certain extent.

[0047] Therefore, according to such a seating isolator 1 according to the present embodiment, as a basic configuration, it has at least a left frame member 2p, a right frame member 2q, and an intermediate frame member 2m located in the front or rear, which are configured in a loop shape by a wire material W made of an elastic material. Each wire material W... is covered by a covering portion 3..., and the covering portions 3... in each frame member 2p, 2q, 2m are sequentially connected to form a frame portion F having an overall vertically long rectangular parallelepiped shape. The lower surface portion 4d is opened, and the remaining surface portions 4p, 4q, 4m, 4r, 4u are closed by a flexible transparent sheet material Sm... to form a sheet cover portion 4, which is an isolator main body portion Um. An isolator window portion Up, Uq having openings 5p, 5q provided at predetermined positions of the sheet material Sm... on the left surface portion 4p surrounded by the left frame member 2p and / or the sheet material Sm on the right surface portion 4q surrounded by the right frame member 2q, a shielding portion 7p, 7q formed by a second sheet material Ss... covering the openings 5p, 5q and provided with entrances and exits 6p, 6q, and a diameter changing portion 8p, 8q capable of changing the sizes of the entrances and exits 6p, 6q. Therefore, even for a user H moving in a wheelchair or the like in a seated state, it is possible to shield almost the entire upper body required for the user H and obtain an internal space with little sense of compression. As a result, it is possible to provide an isolator that is optimal for the user H in a seated state, such as ensuring sufficient shielding performance. Moreover, when not in use, it can be folded into a compact and flat state, so it is excellent in portability and storage. When in use, if taken out from a bag or the like, it can be automatically deployed into a use form by a pop-up method, so it can be quickly set on a wheelchair or the like, and it is excellent in handleability.

[0048] In addition, since the isolator window portions Up, Uq can provide a communication space for communicating the inside and the outside, it is possible to easily take in and out articles such as a towel and a thermometer, and at the same time, it is possible to minimize the internal and external air movement generated at this time. While ensuring sufficient shielding properties, it is possible to easily and quickly perform necessary exchanges between the inside and the outside. Moreover, even for a wheelchair user H, the isolator window portions Up, Uq can enhance multifunctionality and convenience, such as enabling the user to operate the wheels by himself / herself.

[0049] Although the preferred embodiments have been described in detail above, the present invention is not limited to such embodiments, and can be arbitrarily changed, added, or deleted in terms of the detailed configuration, shape, material, quantity, numerical value, etc., without departing from the gist of the present invention.

[0050] For example, it is desirable to use a high-elastic stainless steel material for the wire W, but it can be replaced with other elastic materials having the same function. Also, although it is desirable to form the cross-section of the wire W into a rectangle, for example, the case of selecting other shapes such as a circular cross-section is not excluded. Furthermore, as the sheet material Sm, a 0.2 mm thick thermoplastic polyurethane material is desirable, but it can be replaced with other materials having the same function. On the other hand, although the case where the regulating function part 13 having the pole part 13s is provided has been shown, it can be replaced with other configurations having the same function. Also, the sub-cover part 11 does not necessarily need to be provided, and the elastic expansion and contraction part 12 is not an essential component either. The sub-cover part 11 without the elastic expansion and contraction part 12 may simply be hung down.

[0051] On the other hand, as an example, the isolator window parts Up, Uq are shown in the case where one is provided at each of the left side surface part 4p and the right side surface part 4q, but two or more may be provided as necessary.
