Since the front and rear bodies are made of a flexible first sheet, the vertical and horizontal dimensions of the cover can be freely changed according to the height and width of the human body to be isolated. Covers can be stored in a folded state, save space, can hold multiple covers, even if a large number of human bodies need to be isolated at one time Will not cause any trouble. Moreover, since the cover does not require a dedicated carriage and can be used by being put on a stretcher previously mounted on an emergency vehicle, there is no problem in dealing with an emergency.

  In the case of an isolating cover where the lateral dimension of the belt's free part is shorter than that between the lateral sides of the plate, the belt's free part is secured to the lateral side of the plate so The plate can be reliably brought close to the direction, and the plate can be reliably bent upward in the thickness direction of the cover.

  In the separating cover in which the belt is formed of the first and second belts, the first belt is biased toward the front end portion of the plate and the second belt is biased toward the rear end portion of the plate. By fixing the free part of the belt to the lateral side part of the plate, the front end part side and the rear end part side of the plate can be bent in substantially the same shape, and the curved plate becomes distorted. There is no. This cover can maintain the curved state of the plate by the other of the belts even if one of the free parts of the belt is inadvertently removed from the lateral side of the plate.

  The second opening is formed in the front body, and the second opening is covered with a flexible second sheet having a pathogen barrier property and higher air permeability than the first sheet. The air can be taken into the cover through the second sheet, or the air can be released to the outside of the cover, so that the inside of the cover is not deficient in oxygen and can easily breathe in the cover. . In this cover, since pathogens and radioactive fine particles do not permeate the second sheet, pathogens and radioactive fine particles are not scattered from the second sheet to the outside air, and pathogens and radioactive fine particles are not covered by the second sheet. Never invade.

  The cover has a sleeping bag shape that covers the whole body of the human body with an entrance / exit formed at the peripheral portion thereof, and the entrance / exit can be opened / closed through first fastener means attached to the peripheral portion of the front body and the back body With the cover for isolation, a part of the human body is not exposed from the cover, the whole body can be separated from the outside air, and the scattering of pathogens and radioactive particles from the inside of the cover to the outside air can be surely prevented. It is possible to reliably prevent pathogen infection and radioactive particulate adhesion to the human body. Since this cover can close the entrance / exit via the first fastener means, pathogens and radioactive fine particles are not scattered from the entrance / exit to the outside air, and pathogens and radioactive fine particles do not enter the cover from the entrance / exit.

  In the isolation cover that can be opened and closed through the second fastener means that is formed in the front body and is formed with at least one slit extending in the longitudinal direction at the lower side of the plate and extending in the front body, The doctor can open the slit to measure the pulse and heart rate of the human body in the cover and perform heart massage, and can perform emergency treatment and medical practice without taking the human body out of the cover. Since the cover can close the slit via the second fastener means, the pathogen and radioactive fine particles do not scatter from the slit to the outside air, and the pathogen and radioactive fine particles do not enter the cover from the slit.

  In the isolation cover in which the first ventilation hole is formed in the plate and either the exhaust device having the air purification function or the ventilation device is detachably connected to the first ventilation hole, the exhaust device is provided in the first ventilation hole. When connected, the inside of the cover can be made negative pressure via the exhaust device, and pathogens and radioactive particles in the cover are collected in the exhaust device to ensure that the pathogen and radioactive particles are not scattered to the outside air. Can do. In this cover, when a ventilator is connected to the first vent hole, pathogens and radioactive particles floating in the outside air are collected in the ventilator, and the ventilator is used while preventing the pathogens and radioactive particles from entering the cover. The air purified from the first ventilation hole can be sent into the cover.

  In the isolation cover in which the second ventilation hole is formed in the plate in addition to the first ventilation hole, and either the exhaust device or the ventilation device is detachably connected to the second ventilation hole, the first ventilation hole is exhausted. When one of the device and the ventilation device is connected and the other of the devices is connected to the second ventilation hole, the air in the cover is discharged from the ventilation hole to the outside air through the ventilation device, and the ventilation hole is passed through the ventilation device. The purified air can be sent into the cover from the vent hole, and the air can be circulated to always fill the cover with the purified air.

  The fastening means is formed of a hook member and a loop member of the mechanical fastener, one of the hook member and the loop member is attached to the free part of the belt, and the other of the hook member and the loop member is on the lateral side of the plate. In the attached isolation cover, the fastening state of the free portion of the belt with respect to the lateral side portion of the plate can be maintained using the engaging force between the hook member and the loop member.

  In addition, when using the cover 1A for a patient affected by an infectious disease or an atomic bomb survivor attached with radioactive fine particles, the pressure inside the cover 1A is made lower than that of the outside air via the exhaust device 58, and the inside of the cover 1A It is preferable to prevent the air from being discharged to the outside air except from the exhaust device 58, and at least one of the exhaust device 58 and the ventilation device 59 is attached to one of the vent holes 38 and 39. When using the cover 1A for a healthy person, it is preferable that the air pressure in the cover 1A is made higher than that of the outside air through the ventilation device 59 so that air does not enter the cover 1A from other than the ventilation device 59. At least one of the exhaust device 58 and the ventilation device 59 is attached to one of the vent holes 38 and 39. When only the exhaust device 58 or only the ventilation device 59 is attached to the cover 1A, the cap 44 is fitted into one of the first and second ventilation holes 38 and 39, and one of the ventilation holes 38 and 39 is closed.

  The cover 1A causes the free portion 41 of the first and second belts 36a and 36b to cross the outer surface of the back body 3 and stops the free portion 41 against the lateral side portion 35 of the plate 30 against the rigidity of the plate 30. By wearing, the plate 30 can be curved so as to protrude upward in the thickness direction of the cover 1A, and the head accommodating space 57 capable of accommodating the head of the human body can be formed in the cover 1A.

  The cover 1A can cover the whole body of the human body that needs to be isolated to separate the human body from the outside air, and can prevent the pathogen and radioactive fine particles from scattering to the outside air. Further, even when pathogens and radioactive fine particles are floating in the outside air, the human body can be separated from the outside air to prevent infection of pathogens and attachment of radioactive fine particles to the human body. In the cover 1A, the front and rear bodies 2, 3 are made of a pathogen barrier and breathable fiber nonwoven fabric 8, and pathogens and radioactive fine particles do not permeate the front and rear bodies 2, 3, so that pathogens and radioactive fine particles are contained in the cover 1A. From the outside to the outside air, and pathogens and radioactive fine particles do not enter the cover 1A from the outside air.

  The cover 1A can adjust the radius of curvature of the curved plate 30 by changing the fastening position of the free portion 41 of the belts 36a and 36b with respect to the lateral side portion 35 (loop member 37) of the plate 30, and can be isolated. The horizontal dimension and the height dimension of the head accommodating space 57 can be changed according to the size of the head of the human body. Since the front and rear bodies 2 and 3 of the cover 1A are made of the flexible nonwoven fabric 8, the vertical and horizontal dimensions of the cover 1A can be freely changed according to the height and width of the human body to be isolated.

  The cover 1A can be folded and stored by stacking a plurality of them, and it takes up space for storage and can hold a plurality of covers 1A. Therefore, it is necessary to isolate a large number of human bodies at once. Even so, there will be no hindrance due to lack of numbers. The cover 1A does not require a dedicated carriage and can be used by being placed on a stretcher for an emergency vehicle or a stretcher for a medical institution. The cover 1A can be carried by carrying a plurality of folded ones by emergency personnel or medical personnel, and without removing the human body from the cover 1A, the human body is kept isolated and the cover 1A together with the bed of the medical institution or operation. Since it can be moved to a table, there will be no trouble in emergency response.

  In the cover 1A, since the belt 36 is formed by the first belt 36a and the second belt 36b, the free portion 41 of the belts 36a and 36b is fastened to the side portion 35 of the plate 30 so that the plate 30 The front end portion 32 side and the rear end portion 33 side can be curved in substantially the same shape, and the curved plate 30 does not become distorted. The cover 1A can maintain the curved state of the plate 30 by the other of the belts 36a and 36b even if one of the free portions 41 of the belts 36a and 36b is inadvertently detached from the side portion 35 of the plate 30. it can.

  In the cover 1A, since the nonwoven fabric 31 (second sheet) covering the second opening 29 has a pathogen barrier property and higher air permeability than the nonwoven fabric 8 (first sheet), air easily penetrates the nonwoven fabric 31, and the nonwoven fabric 31 The air can be taken into the cover 1A or released to the outside of the cover 1A via 31, and the inside of the cover 1A does not become deficient in oxygen and can easily breathe in the cover 1A. Since the pathogen and radioactive fine particles do not permeate the nonwoven fabric 31, the cover 1A does not scatter the pathogen or radioactive fine particles from the nonwoven fabric 31 to the outside air, and the pathogen or radioactive fine particles enter the cover 1A from the nonwoven fabric 31. There is nothing to do.

  Since the cover 1A is formed with a slit 52 extending in the longitudinal direction in the front body 2, an emergency crew or doctor opens the slit 52 and measures the pulse and heart rate of the human body accommodated in the cover 1A or a heart massage. First-aid treatment and medical practice can be performed without taking the human body out of the cover 1A. In the cover 1 </ b> A, the entrance / exit 27 and the slit 52 can be closed via fasteners 23 and 49 (first and second fastener means), and the entrance / exit 27 and the slit 52 can be sealed via adhesives 25 and 50. Therefore, pathogens and radioactive fine particles are not scattered from the entrance 27 and the slit 52 to the outside air, and pathogens and radioactive fine particles do not enter the cover 1A from the entrance 27 and the slit 52.

  In the cover 1A, when the exhaust device 58 is connected to one of the vent holes 38 and 39, the inside of the cover 1A can be made negative pressure via the exhaust device 58, and pathogens and radioactive fine particles in the cover 1A are exhausted. 58, it is possible to reliably prevent pathogens and radioactive fine particles from being scattered to the outside air. In the cover 1A, when the ventilation device 59 is connected to one of the vent holes 38 and 39, pathogens and radioactive particles floating in the outside air are collected by the ventilation device 59, and the pathogen and radioactive particles are prevented from entering the cover 1A. While being prevented, the purified air can be sent into the cover 1A through the vent holes 38 and 39 through the ventilation device 59. When one of the exhaust device 58 and the ventilation device 59 is connected to one of the vent holes 38 and 39 and the other of the devices 58 and 59 is connected to the other of the vent holes 38 and 39, the exhaust device 58 is interposed. The air purified from the vent holes 38 and 39 can be sent into the cover 1A through the venting device 59 while the air in the cover 1A is released to the outside air from the vent holes 38 and 39, and the air is circulated. Can do.

  FIG. 14 is a perspective view of the cover 1 </ b> B of FIG. 10 shown in a use state in which the human body 100 is accommodated. In FIG. 14, the cover 1 </ b> A and the human body 100 are placed on the stretcher 60. An example of the procedure using this cover 1B is as follows. After peeling the release paper 66 from the free part 41 of the belt 36 to expose the adhesive 65, the free part 41 of the belt 36 is crossed across the outer surface of the back body 3, and the belt 36 is freed against the rigidity of the plate 30. The part 41 is fixed to the outer surface of the side part 35 of the plate 30. In order to fix the free part 41 to the plate 30, the adhesive 65 applied to the free part 41 may be pressed against the plate 30. When the free portion 41 is fastened to the plate 30, the side portions 34, 35 of the plate 30 approach each other, the plate 30 is elastically deformed and curved so as to protrude upward in the thickness direction of the cover 1B, and the cover 1B has front and back body parts. A head receiving space 57 surrounded by the second and third plates 30 is formed. The space 57 has a horizontal dimension and a height dimension that can cover the head 101 of the human body 100. The horizontal dimension and the height dimension of the space 57 can be adjusted by changing the fixing position of the free part 41 of the belt 36 with respect to the side part 35 of the plate 30.

  After the space 57 is created, the cap 44 is removed from the cylindrical portion 43 of the first ventilation hole 38 to open the ventilation hole 38, and either the exhaust device 58 or the ventilation device 59 is attached to the first ventilation hole 38. Next, the slider 64 is moved to open the entrance / exit 27, and the patient, the survivor, and the healthy person are put into the cover 1B through the entrance / exit 27 and laid on their back, and the slider 64 is moved again to close the entrance / exit 27. In the cover 1 </ b> B, the upper body is covered with the cover 1 </ b> B with the head 101 of the human body 100 indicated by a two-dot chain line in FIG. 13 positioned in the space 57. When the width of the human body 100 accommodated in the cover 1B is smaller than the lateral dimension of the cover 1B, the lateral dimensions of the cover 1B are reduced by bending both side portions 6 and 7 inward in the lateral direction. After the human body 100 is accommodated in the cover 1B, the cover 1B is placed on the stretcher 60, the stretcher 60 is mounted on an emergency vehicle, and the human body 100 is transported to a medical institution, or the cover 1B is covered via the stretcher 60. The human body 100 is transported to the treatment room or examination room together with 1B.

  In addition, when using the cover 1B for a patient affected by an infectious disease or an atomic bomb survivor to which radioactive fine particles have adhered, the pressure inside the cover 1B is made lower than that of the outside air via the exhaust device 58, and the inside of the cover 1B It is preferable to prevent air from being discharged to the outside air from other than the exhaust device 58, and the exhaust device 58 is attached to the vent hole 38. When using the cover 1B for a healthy person, it is preferable that the air pressure in the cover 1B is made higher than that of outside air through the ventilation device 59 so that air does not enter the cover 1B from other than the ventilation device 59. The ventilation device 59 is attached to the vent hole 38.

  The cover 1 </ b> B traverses the free portion 41 of the belt 36 across the outer surface of the back body 3 and secures the free portion 41 to the lateral side portion 35 of the plate 30 against the rigidity of the plate 30. Can be curved so as to protrude upward in the thickness direction of the cover 1B, and a head accommodation space 57 capable of accommodating the head of a human body can be formed in the cover 1B.

  The cover 1B can enclose the upper body of the human body that needs to be isolated to separate the human body from the outside air, and can prevent the pathogen and radioactive fine particles from scattering to the outside air. Further, even when pathogens and radioactive fine particles are floating in the outside air, the human body can be separated from the outside air to prevent infection of pathogens and attachment of radioactive fine particles to the human body. In the cover 1B, the front and rear bodies 2, 3 are made from the pathogen barrier and breathable fiber nonwoven fabric 8, so that pathogens and radioactive fine particles do not pass through the front and rear bodies 2, 3.

  The cover 1B can adjust the curvature radius of the curved plate 30 by changing the fastening position of the free portion 41 of the belt 36 with respect to the lateral side portion 35 of the plate 30, and the size of the head of the human body to be isolated can be adjusted. The horizontal dimension and height dimension of the head accommodating space 57 can be changed according to the height. Since the front and rear bodies 2 and 3 of the cover 1B are made of flexible fiber nonwoven fabric, the horizontal dimension of the cover 1B can be freely changed according to the width of the human body to be isolated.

  As in FIG. 1, the cover 1B can be stored in a folded state, saves space, can hold a plurality of covers 1B, and it is necessary to isolate a large number of human bodies at once.

Therefore, the nonwoven fabric 8 and the nonwoven fabric 31 have a high barrier property with respect to a pathogen (bacteria and a virus), and are substantially pathogen-impermeable. When the collection rate of these nonwoven fabrics 8 and 31 is less than 99.5%, pathogens and radioactive fine particles permeate through the front and rear bodies 2 and 3 and the nonwoven fabric 31 and scatter to the outside air from the covers 1A and 1B, or pathogens and radioactive fine particles. May intrude into the covers 1A, 1B.

  As the fiber nonwoven fabrics 8 and 31 forming the first sheet and the second sheet, nonwoven fabrics manufactured by each method of spun lace, needle punch, melt blown, thermal bond, spun bond, and chemical bond can be used. The nonwoven fabrics 8 and 31 are composite nonwoven fabrics (SM nonwoven fabric, SMS nonwoven fabric, SMMS) in which nonwoven fabrics by a spunbond method having high strength and good flexibility are superimposed on both sides or one side of a nonwoven fabric by melt-blown method having high water resistance. Nonwoven fabric) can also be used. Polyester, polyacrylonitrile, polyvinyl chloride, polyethylene, polypropylene, and polystyrene can be used for the constituent fibers of the nonwoven fabrics 8 and 31. As the constituent fibers, core-sheath type composite fibers, parallel type composite fibers, atypical hollow fibers, microporous fibers, and bonded type composite fibers can also be used.

  The front and rear bodies 2 and 3 are laminated with a pathogen-impermeable and aeration-impermeable liquid-permeable plastic film, a pathogen-impermeable and aeration-impermeable liquid-impervious fiber nonwoven fabric and a pathogen-impermeable and aeration-impermeable liquid-impervious plastic film. Any of the composite sheets can also be used. The plate 30 can be made of a thermoplastic synthetic resin such as polyester, polyacrylonitrile, polyvinyl chloride, polyethylene, polypropylene, or polystyrene. The plate 30 has a predetermined rigidity and thickness dimension, and is impermeable to liquid as well as impermeable to pathogens. The belt 36 can be made of the same fibrous nonwoven fabric 8, 31 as the first and second sheets or a thermoplastic synthetic resin film.

  Adhesion between the front and rear bodies 2 and 3, adhesion of the plate 30 and the nonwoven fabric 31 (second sheet) to the front body 2, and adhesion of the belt 36 to the plate 30 are caused by heat from an adhesive or heat seal or sonic seal. Welding means can be used. Sewing means using a sewing machine can be used for fixing the front and rear bodies 2 and 3 and fixing the nonwoven fabric 31 to the front body 2. As the adhesive or the pressure-sensitive adhesive, a hot melt system, an acrylic system, or a rubber system can be used.

  In the cover 1A of FIG. 1, the zip fastener 23 is used as a fastener means, but the rail fastener 61 can also be used like the cover 1B of FIG. In the cover 1 </ b> A of FIG. 1, the adhesive 50 can be applied to the free part 41 of the belt 36 and the attachment of the loop member 37 to the plate 30 can be omitted.
