BACKGROUND OF THE INVENTION
The present invention relates to a tent for making a negative pressure or a positive pressure inside a tent which is a living space of the tent.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, large-scale hospitals have been provided with a negative pressure chamber in which the atmospheric pressure in the room is lower than the outside air pressure in order to isolate patients with air infections so that viruses in the room do not escape outside. However, the number of hospitals with negative pressure chambers is limited, and patients with air infections do not always come to the hospital with negative pressure chambers from the beginning.
In addition, if a patient with airborne infection is examined in a normal examination room, the virus that causes airborne infection may spread not only in the examination room, but also throughout the hospital building such as the reception and waiting room. It becomes. However, it is considered that it is very difficult to provide a negative pressure chamber, which is a facility specialized for a specific purpose of use, in all hospitals due to problems such as high equipment costs.
Therefore, a negative pressure facility that can be set up in an emergency is desired.
[0003]
Contrary to the examination room for patients with air infections, in the operating room, positive pressure is applied so that bacteria, viruses and the like do not enter from the outside.
However, even if a temporary hospital is established in a disaster area or the like, it takes time to establish a positive pressure facility and it is difficult to take a sudden response.
Therefore, a positive pressure facility that can be set up in an emergency is desired.
[0004]
As a tent with positive internal pressure, almost no struts are used, the outside air is forced into the bag-shaped awning at all times, and the structure of the tent is determined by the difference between the atmospheric pressure inside and outside the tent. There is a mechanism that supports the air in the tent through the space between the awning and the ground.
However, since such a tent cannot make a specific place to exhaust, the air in the tent cannot be efficiently exchanged. In other words, the air in the vicinity of the place where the air is being sent into the tent is simply replaced with new air through the space between the awning and the ground, and the air in the tent cannot be replaced efficiently.

[Problems to be solved by the invention]
When the tent is used as an examination room, a hospital room, or an operating room, a plurality of people enter the tent for a long time. For this reason, it is necessary to prevent the air in the tent from running out of oxygen. A normal tent has a large entrance and exit, and the entrance can be opened. However, in order to keep the internal space of the tent at a negative pressure or a positive pressure, the large entrance cannot be opened.
Therefore, a structure is required that can efficiently replace the air in the tent while keeping the internal space of the tent at a negative pressure or a positive pressure.
[0007]
[Means for solving]
The present invention solves the above problems by using a tent having a specific structure.
The invention according to claim 1 has an intake port and an exhaust port, and the tent can be self-supported even when intake and / or exhaust are forcibly performed through the filter and no intake and exhaust are performed. It is a tent that can create negative or positive pressure in the interior space
Invention of Claim 2 is the tent which can make the internal space self-supporting by the frame | skeleton which consists of an air tube into a negative pressure or a positive pressure in addition to the structure of Claim 1,
According to a third aspect of the present invention, in addition to the structure of the first or second aspect, the awning has an outer awning outside the skeleton supporting the tent, an inner awning inside the skeleton, and a floor on which the floor of the tent is formed. It is a tent that has a laying sheet and can make the inner space where the outer awning or / and the inner awning and the floor laying sheet are joined by a fixing tool to a negative pressure or a positive pressure.
[0008]
The tent of the present invention may have a metal pipe or a synthetic resin pipe as a skeleton, or may have an air tube as a skeleton. However, in consideration of convenience during storage and transportation, a tent having an air tube as a skeleton is preferable.
[0009]
In the present invention, a tent that can stand on its own even when no air is exhausted or exhausted is a tent that cannot maintain the shape of the tent unless it is constantly forced to inhale as shown in the prior art. Instead, it is a tent that can be held in a state where forced intake and exhaust are not performed by a metal pipe, an air tube, or the like.
For example, when using the tent of the present invention as a hospital room, it is necessary to carry a large bed into the tent, and when using it as an operating room, it is necessary to carry in equipment such as an operating table. Thus, it is necessary to open the entrance of the tent greatly when loading the equipment, and in the case of a tent that maintains the shape due to the pressure difference between the inside of the tent and the outside, the tent is squeezed when the equipment is loaded, There is a risk that the carrying-in route will be blocked and the work cannot be performed quickly.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, aspects of embodiments will be described with reference to the drawings.
[0011]
There are various methods for keeping the internal space of the tent at a negative pressure.
For example, as shown in FIG. 1 (plan view of the tent of the present invention), an air cleaner having a filter is provided in the tent. There is a method in which clean air is forcibly exhausted by a compressor or an air purifier fan through the air purifier, and then naturally sucked from the intake port. Further, a regulator (not shown) may be provided at the intake port to adjust the intake air amount.
In addition, as shown in FIG. 2, an air purifier having a filter is provided in the tent, and clean air is forced out of the tent through the air purifier by a compressor or an air purifier fan. There is a method of forcibly taking outside air into the tent using a fan or a compressor 4. At this time, by separating the position of the exhaust air cleaner or the exhaust compressor from the position of the intake port, or by starting the exhaust air cleaner or the exhaust compressor before the intake compressor, Can be kept at negative pressure.
[0012]
As shown in FIG. 3, there is a method in which an air purifier having a filter is provided outside the tent, and clean air is forcibly exhausted to the outside through the air purifier and is naturally aspirated from the intake port. Further, a regulator may be provided at the intake port to adjust the intake air amount.
In addition, as shown in FIG. 4, an air cleaner having a filter is provided outside the tent, and clean air is forcibly exhausted by the air cleaner fan through the air cleaner, while another fan or There is a method of forcibly taking outside air into the tent using the compressor 4. At this time, by separating the position of the exhaust air cleaner or the exhaust compressor from the position of the intake port, or by starting the exhaust air cleaner or the exhaust compressor before the intake compressor, Can be kept at negative pressure.
[0013]
There are various methods for keeping the internal space of the tent at a positive pressure.
By placing the interior space of the tent in a negative pressure and reversing the air flow, the interior space of the tent can be made positive pressure.
[0014]
When the air cleaner is installed inside the tent, it can be used not only as a device for performing intake and exhaust, but also as an air cleaner for the internal space of the tent.
For example, when the internal space of the tent is set to negative pressure, the air exhausted from the air cleaner is exhausted to both the outside and the internal space of the tent, and the internal space of the tent is positively pressurized. In this case, it is possible to take in the air sucked by the air cleaner from both the outside and the interior space of the tent.
[0015]
As described above, the internal space of the tent can be maintained at a negative pressure or a positive pressure. However, from the viewpoint of air replacement in the internal space of the tent, the positions of the intake port and the exhaust port are preferably separated as much as possible. . As shown in FIGS. 1 to 4, if the tent has one intake surface or one end in the length direction and an exhaust port at the other end or the other end, the air replacement effect in the inner space of the tent is extremely Very expensive.
[0016]
The structure of the regulator is not particularly limited as long as the flow rate of air can be adjusted. If an example is given as a concrete structure, a plurality of plate-like bodies are arranged and rotated by changing the opening area as provided at the outlet of an air conditioner or the like. There are structures that adjust the flow rate of air.
[0017]
In the tent, the tent plays a major role of separating the inner space of the tent from the outside world, and is absolutely indispensable when the inner space of the tent is set to a negative pressure or a positive pressure. Therefore, in the unlikely event that a hole is opened in the tent, it may lead to a fatal accident.
Therefore, in order to improve the safety of the tent of the present invention, the tent tent can be doubled.
[0018]
When the tent tent is doubled, the outer tent is provided outside the tent column (mainly composed of a metal pipe, a plastic pipe, an air tube, etc.) as in the case of a normal single awning. On the other hand, the inner awning is preferably provided on the inner side of the tent column from the functional aspect.
For joining the inner awning and the tent column, various methods such as joining with a fastener or a belt can be employed.
In the present invention, when the internal space of the tent is set to a negative pressure, the inner awning is preferably fixed to the support of the tent using a fastener or other fastener.
[0019]
In the tent of the present invention, a tent floor sheet and an outer awning or / and a tent floor sheet and an inner awning are fastened to a fastener, a velvet fastener, etc. It is preferable to fix with the fixing tool. Moreover, it is preferable that the outer awning or the inner awning and the floor sheet are fixed over the entire circumference of the floor sheet.
As a result, a pressure difference between the internal space of the tent and the outside can be efficiently generated and maintained.
[0020]
In addition, when people go in and out, the entrance and exit of the tent must be opened. However, by opening the doorway, the pressure difference between the internal space of the tent and the outside world is reduced at once.
[0021]
As one of the solutions to this problem, when a front chamber having a space narrower than the inner space of the tent is provided at the entrance of the tent, and the inner space of the tent is set to a negative pressure, the front chamber is also set to a negative pressure, When the internal space of the tent is set to a positive pressure, there is a method in which the anterior chamber is also set to a positive pressure.
If you want to enter the tent from outside, first open the front door and enter the front room. At this time, by opening the entrance of the front chamber, the pressure difference between the internal space of the front chamber and the outside is reduced. However, it is possible to easily adjust the atmospheric pressure by making the internal space of the front chamber narrower than the internal space of the tent. When the atmospheric pressure in the interior space of the front chamber has been adjusted to some extent, the pressure change in the interior space of the tent can be reduced by opening the entrance of the tent and entering the interior space of the tent.
[0022]
The air pressure in the interior space of the anterior chamber may be adjusted by installing an independent fan or compressor in the anterior chamber, but a duct 4c that connects the interior space of the tent and the interior space of the anterior chamber is provided to provide an internal space for the tent. It is also possible to adjust the pressure in the anterior chamber through. Further, by making the duct freely openable / closable, it becomes easy to maintain the atmospheric pressure in the interior space of the tent when no person enters or exits.
[0023]
Some entrances to the tent and the front room have two tarpaulins suspended like goodwill so that they can be rolled up and released. However, since the tent of the present invention aims to make the internal space of the tent negative or positive, it is difficult for the conventional structure to efficiently generate a pressure difference from the outside.
Therefore, it is preferable to suspend the entrance / exit of the tent of the present invention so that a part of the two tarpaulins 1a overlap.
The lower ends of the two tarpaulins 1a constituting the entrance / exit are fixed by a velvet fastener VF and a velvet fastener VF ′ on the surface of a sill 1e having a height of about 3 cm. Moreover, it is preferable that the side ends of the two tarpaulins 1a constituting the doorway are fixed to the outer awning 1b by fasteners F.
[0024]
Opening fasteners F that join the side ends of the two tarpaulins 1a that make up the entrance of the tent and the tent on the end surface of the tent, and roll up and fix the tarpaulins, making it easy to carry in equipment It is possible to secure a carry-in route.
On the contrary, when used as a negative pressure chamber or a positive pressure chamber, the tarpaulin 1a is prevented from being turned up by wind or the like, and the pressure difference between the internal space of the tent and the outside is easily maintained.
[0025]
The two tarpaulins 1a constituting the entrance and exit of the tent are provided with a velvet fastener VF at the lower end, and a velvet fastener VF 'is provided on the surface of the entrance 1e to be detachable. When the sill is made of a flexible material such as tarpaulin, a stretcher or a carriage can be moved in and out as it is, which is convenient.
[0026]
【The invention's effect】
The tent of the present invention has a structure different from the conventional tent as described above, and thus is suitable for making the internal space of the tent negative pressure or positive pressure. Moreover, even when an emergency is required, it is possible to easily carry equipment into the tent.
