DETAILED DESCRIPTION OF THE INVENTION

[0017] <First Embodiment> Hereinafter, a negative pressure shield device according to the first embodiment of the present invention will be described with reference to the drawings. The negative pressure shield device according to the first embodiment is a negative pressure shield device mounted on an ambulance "Triheart" manufactured by Sapporo Body Industry Co., Ltd.

[0018] As shown in FIGS. 1 to 4, the negative pressure shielding device 1 includes a shielding main body 2 and a connection part 3. The shielding main body 2 is installed in the patient room 20 of the ambulance and covers the patient 23 on the stretcher 22 mounted on the stretcher stand 21 in the patient room 20. The connection part 3 communicates with the inside of the shielding main body 2 and is connected to the ventilation opening 24 provided in the upper part of the patient room 20.

[0019] The shielding main body 2 is configured to include a ceiling part 4 and a peripheral wall part 5. The ceiling part 4 and the peripheral wall part 5 are each configured using a flexible and transparent sheet. In the present embodiment, the ceiling part 4 and the peripheral wall part 5 are configured using a vinyl sheet having a certain thickness and a strength that is not easily torn.

[0020] The ceiling part 4 has a shape corresponding to the shape of the stretcher stand 21 in plan view. In the present embodiment, the ceiling part 4 has a rectangular shape. The ceiling part 4 is disposed at a position close to the ceiling of the patient room 20.

[0021] The peripheral wall part 5 is configured to include a side wall part 6, a front wall part 7, and a rear wall part 8. The side wall part 6 is a part along the side wall of the patient room 20. The front wall part 7 is a part on the driver's seat side of the ambulance. The rear wall part 8 is a part on the side of the rear door of the patient room 20. The side wall part 6 has a width corresponding to the length in the front-rear direction of the stretcher stand 21. The front wall part 7 and the rear wall part 8 each have a width corresponding to the width of the stretcher stand 21. The side wall part 6, the front wall part 7, and the rear wall part 8 hang down from each side of the ceiling part 4 and have a length that contacts or is close to the floor surface of the patient room 20.

[0022] As a result, the shielding main body 2 has a vertically long box shape with an open lower part, houses the stretcher stand 21, the stretcher 22, and the patient 23 inside, and covers the entire body of the patient 23.

[0023] Note that the stretcher stand 21 is movable in the vehicle width direction. However, the shield body 2 has a sufficient length in the vertical direction. For this reason, no matter where the stretcher stand 21 is located, it does not protrude from the shield body 2 and is always maintained in a state of being housed inside the shield body 2.

[0024] Also, due to the relationship between the height dimensions of the stretcher stand 21 and the stretcher 22, the patient 23 is located at a height position approximately half of the height dimension of the patient room 20. Therefore, the distance from the patient 23 to the ceiling portion 4 of the shield body 2 is sufficiently separated. For this reason, the patient 23 can take a posture of raising the upper body in the internal space (isolation room) of the shield body 2.

[0025] The connecting portion 3 is in the shape of a square tube or a round tube and serves as an intake duct. An opening is formed in the ceiling portion 4, and one open end portion of the connecting portion 3 is attached to this opening. The connecting portion 3 is formed by making a flexible and transparent sheet into a tubular shape. In the present embodiment, the connecting portion 3 is configured using a vinyl sheet having a certain thickness and strength that is not easily torn, similar to the shield body 2. Thereby, the connecting portion 3 has flexibility, and the position and orientation of the other open end portion can be freely adjusted within a predetermined range. A ventilation opening 24 is provided in the ceiling of the patient room 20 directly above the opening, and the other open end portion of the connecting portion 3 is attached so as to cover (surround) the ventilation opening 24. For the attachment of the connecting portion 3 to the ceiling of the patient room 20 around the ventilation opening 24, various known means such as tape, hook-and-loop fasteners, and adhesives are used.

[0026] When the ventilation fan is turned on, the air inside the shield body 2 is sucked from the ventilation opening 24 through the inside of the connecting portion 3. Thereby, the inside of the shield body 2 becomes a negative pressure atmosphere, and the exhaled breath of the patient 23 does not leak out from the shield body 2 to the outside and is all discharged to the outside of the patient room 20 through the connecting portion 3 and the ventilation opening 24. For this reason, the risk of infection of the emergency team members (or in the case of an ambulance, medical personnel such as doctors and nurses) in the driver's seat and the patient room 20 can be eliminated.

[0027] The ceiling portion 4 is provided with locking portions 9 along the front - rear direction within the patient room 20. More specifically, the ceiling portion 4 is provided with a pair of left - and - right locking portions 9, 9 along each side edge. Therefore, the interval between the pair of locking portions 9, 9 is an interval corresponding to the width of the stretcher stand 21. The locking portion 9 is formed by joining (for example, heat - sealing) the side edge of the sheet of the ceiling portion 4 and the upper edge of the sheet of the side wall portion 6 with a predetermined width. For this reason, the locking portion 9 is a strip - shaped piece extending along the front - rear direction within the patient room 20, and is a reinforced strip - shaped piece with an increased thickness compared to other sheets.

[0028] The locking portion 9 is provided with a plurality of locking holes 9a,... at a predetermined interval. In the present embodiment, the locking holes 9a are holes of rivets attached to the strip - shaped piece.

[0029] On the ceiling of the patient room 20, a pair of handrails 25, 25 extending along the front - rear direction of the patient room 20 and having an interval and being parallel are provided. The interval between the pair of handrails 25, 25 is an interval corresponding to the width of the stretcher stand 21. One of the S - shaped hooks 26 is hung on the locking hole 9a of the locking portion 9, and the other of the S - shaped hooks 26 is hung on the handrail 25. Thereby, the shield body 2 is suspended and supported in a state where the box - shaped shape is maintained within the patient room 20.

[0030] The shield body 2 is provided with a loading / unloading port in the rear wall portion 8. In the present embodiment, an opening / closing line 10, for example, by a fastener, is provided along the two orthogonal sides of the upper edge and the side edge of the rear wall portion 8. By opening the opening / closing line 10, the loading / unloading port is opened and the stretcher 22 can be loaded / unloaded. On the other hand, by closing the opening / closing line 10, the loading / unloading port is closed and the shield body 2 can be sealed.

[0031] The shield body 2 is provided with a plurality of arm insertion openings at appropriate positions. For example, a pair of arm insertion openings are provided near the front wall portion 7 of the side wall portion 6 for accessing the upper body of the patient 23. Another pair of arm insertion openings are provided near the rear wall portion 8 of the side wall portion 6 for accessing the lower body of the patient 23. Still another pair of arm insertion openings are provided on the front wall portion 7 for accessing the head and face of the patient 23. In the present embodiment, for example, an opening / closing line 11 by a fastener is provided. By opening this opening / closing line 11, the arm insertion opening becomes open and the arm can be inserted into the inside of the shield body 2. Note that a shielding body 12 is provided to cover the opening / closing line 11 from the inside so that the contaminated air (such as droplets) inside the shield body 2 does not leak out through the arm insertion opening. The shielding body 12 is configured using a sheet of the same material as the shield body 2, and the upper edge is joined (for example, heat-sealed) to the shield body 2.

[0032] As shown in FIG. 5, the shield body 2 is configured to be able to be flattened by separating appropriate sides of the ceiling portion 4, the side wall portion 6, the front wall portion 7, and the rear wall portion 8. Specifically, an opening / closing line by an appropriate fastener, such as the opening / closing line 10 by a fastener, is provided to enable the shield body 2 to be flattened.

[0033] Thus, according to the negative pressure shield device 1 according to the present embodiment, only a patient-exclusive compartment (the upper region of the stretcher 22), which is a part of the space in the patient room 20, can be made negative pressure, eliminating the risk of infection to others in the vehicle, and preferably preventing the scattering and adhesion of infectious substances to articles such as medical devices provided in the patient room 20, and effectively preventing secondary infection.

[0034] Also, according to the negative pressure shield device 1 according to the present embodiment, not only is the periphery of the patient 23 surrounded by the peripheral wall portion 5 of the shield body 2, but by adding the ceiling portion 4 as a configuration of the shield body 2, the periphery of the patient 23 can be wrapped and surrounded, and scattering from above can also be preferably prevented.

[0035] Moreover, according to the negative pressure shielding device 1 according to the present embodiment, it can be installed simply by hanging the shield body 2 on the handrails 25, 25 provided at the upper part of the patient room 20 using the S-shaped hook 26, and can be easily attached. Conversely, the shield body 2 can be removed simply by removing the S-shaped hook 26, and maintenance can be easily performed.

[0036] Moreover, according to the negative pressure shielding device 1 according to the present embodiment, since the shield body 2 is transparent, the overall condition of the patient can be visually observed.

[0037] Moreover, according to the negative pressure shielding device 1 according to the present embodiment, since the shield body 2 can be deployed (disassembled) in a flat state, it can be spread out on the ground (using a deck brush or the like) and washed thoroughly with water during cleaning and disinfection work.

[0038] Moreover, according to the negative pressure shielding device 1 according to the present embodiment, since there is sufficient separation between the patient 23 and the ceiling portion 4 of the shield body 2, it can also be applied to patients who cannot assume a supine position (for example, asthmatic patients who preferably assume a posture with the upper body raised, patients who need to stand on their feet, etc.). That is, the negative pressure shielding device 1 according to the present embodiment has a very high degree of freedom in the patient's body position.

[0039] <Second Embodiment> Next, the negative pressure shielding device according to the second embodiment of the present invention will be described with reference to the drawings. The negative pressure shielding device according to the second embodiment is a negative pressure shielding device mounted on Toyota's ambulance "Hi-Medic" and Nissan's ambulance "Paramedic".

[0040] In these vehicle models, when viewed from the rear side, the stretcher mount 21 is provided at the right half position of the patient room 20, and the ceiling of the patient room 20 is not flat but has a curved surface that slopes downward toward the side wall of the patient room 20. For this reason, as shown in FIGS. 6 and 7, in the negative pressure shielding device 1 according to the present embodiment, the ceiling portion 4 is inclined in accordance with the ceiling of the patient room 20.

[0041] In addition, only one handrail is provided on the ceiling of the patient room 20. Therefore, the higher locking portion 9 is hung on this handrail, and the lower locking portion 9 is hung on a handrail or the like provided on the upper part of the side wall of the patient room 20.

[0042] Moreover, since there is no space for a person to enter between the side wall portion 6 on the side wall side of the patient room 20 and the side wall of the patient room 20, no arm insertion port is provided in this side wall portion 6. Instead, as shown in FIG. 7, one or more similar configurations are provided (for example, the opening / closing line 13 and the shielding body 14 by a fastener), and it is used as an inlet for drawing in wires such as cords and cables of medical devices provided on the side wall (shelf) of the patient room 20. In this case, the fastener must be able to be opened and closed even from inside the shield body 2. For this reason, as the fastener, a type of fastener having pull handles on both the front and back sides of the slider (so-called double-sided slider type fastener) is used.

[0043] Thus, the negative pressure shield device 1 according to the present embodiment also exhibits the same operational effects as the negative pressure shield device 1 according to the first embodiment.

[0044] It should be noted that the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the gist of the present invention.

[0045] For example, in each of the above-described embodiments, the ceiling portion 4 and the peripheral wall portion 5 are configured with a clear boundary. However, the present invention is not limited to this. The physical boundary between the ceiling portion and the peripheral wall portion may not be clear.

[0046] Also, in each of the above-described embodiments, the ceiling portion 4 is configured using a vinyl sheet, similar to the peripheral wall portion 5. However, the present invention is not limited to this. The ceiling portion may be configured using a material different from that of the peripheral wall portion, or may not be transparent.

[0047] In addition, in each of the above embodiments, the shield body 2 is configured using only a vinyl sheet and is maintained in an appropriate shape by utilizing the handrail 25, so a frame or the like is not used. However, the present invention is not limited to this. In order to maintain the shield body 2 in an appropriate shape, a frame or the like may be used to obtain formability.

[0048] In addition, in each of the above embodiments, the shield body 2 covers the entire body of the patient 23 by having a cross-sectional shape corresponding to the shape of the stretcher 22. However, the present invention is not limited to this. The length of the shield body in the front-rear direction may be shortened to cover only the upper body or only the head of the patient.

[0049] In addition, in each of the above embodiments, as shown in FIG. 9, the shield body 2 is locked to the upper part in the patient room 20 using the S-shaped hook 26. However, the present invention is not limited to this. As means for fixing the shield body 2 to the upper part in the patient room 20, various known means such as a string, a tape, a magnetic hook, and a hook-and-loop fastener can be used.

[0050] In addition, in each of the above embodiments, as shown in FIG. 9, an air intake port 15 can be provided. The air intake port 15 is an opening formed at an appropriate position of the shield body 2. Additionally, a high-precision filter 16 of a HEPA filter can be provided for this opening. Thereby, clean air can be taken into the inside of the shield body 2. The air intake port 15 is preferably provided at a location on the peripheral wall portion 5 that is away from the connection portion 3, for example, on the front wall portion 7 or on the side wall portion 6 closer to the front wall portion 7.

[0051] In addition, in each of the above embodiments, as shown in FIG. 9, a high-precision filter 17 of a HEPA filter can be provided at the connection portion 3. Thereby, the air can be purified and discharged outside the patient room 20.

[0052] Also, in each of the above embodiments, as shown in FIG. 10, the second connection portion 18 can be provided. The connection portion 18 is connected to an ozone gas generator installed in the patient room 20. Thereby, only the inside of the shield body 2 can be efficiently sterilized. The connection portion 18 is formed by making a flexible and transparent sheet into a cylindrical shape. The connection portion 18 has the same structure as the connection portion 3, apart from fine differences such as size and shape. In the present embodiment, the connection portion 18 is configured using a vinyl sheet that has a certain thickness like the shield body 2 and has a strength that is not easily torn. Thereby, the connection portion 18 has flexibility and can freely adjust the position and orientation of the other opening end portion within a predetermined range. The ozone gas generator is usually installed on the side wall (shelf) of the patient room 20. In this case, the connection portion 18 is provided on the side wall portion 6.

[0053] Also, in the above embodiment, the arm insertion opening is configured using, for example, an opening / closing line 11 with a fastener. However, the present invention is not limited to this. For example, it goes without saying that various arm insertion openings such as a general circular arm insertion opening described in Patent Documents 1 and 2 can be adopted.
