Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an emergency safety device for a therapeutic high-pressure tank that is installed in a high-pressure tank for performing hyperbaric oxygen therapy (barotherapy).

<Conventional technology> Conventionally, commonly used stimulation associated with changes in atmospheric pressure is used to treat various symptoms (gas poisoning, decompression sickness, myocardial infarction, sequelae of stroke, rheumatism, hypertension, whiplash, etc.) A high-pressure tank for hyperbaric oxygen therapy has an entrance/exit door at one end of the cylindrical tank body, an oxygen inhalation device, lighting, a chair, an intercom, etc. inside, and the tank itself has an air supply system, exhaust system, and ventilation system. The system is configured with appropriate piping. However, the entrance/exit door in this case is of the type that is opened and closed by technical staff or the like from outside the tank. For this reason, once a patient is inside the tank, he or she suffers from a sense of isolation due to the airtightness, which can even cause mental pain. In particular, the possibility of escape from the recent earthquake disasters has become a source of concern. Of course, in addition to this, consideration must also be given to the possibility that technical staff may become unable to operate the entrance/exit door due to sudden illness, etc., or their absence from their post due to a disaster.

In this regard, current high-pressure tanks do not have emergency escape doors, and improvements are needed as soon as possible. However, in the case of a large high-pressure tank with a main chamber and an auxiliary chamber, which is a Type 2 device, there is an idea to have a small clutch door on the side wall through which workers go in and out double as an escape door. (Previously submitted Utility Model Application Publication No. 59-41431), the clutch mechanism of the door in this case has a structure that protrudes considerably from the outer surface of the tank. Therefore, under the above conditions, it is assumed that the walls, ceiling, etc. of the building will collapse due to an earthquake or the like and directly block the door, making it impossible to escape.

<Problems that the invention aims to solve> In view of the above-mentioned circumstances, this invention has a door and installation structure that allows escape (the door can be opened freely) even if the building collapses toward the door of the tank body in the event of an earthquake disaster, etc. The object of the present invention is to provide an emergency safety device for a high-pressure tank for medical treatment, which makes it known that there is a person in the tank and allows for quick rescue.

<Means for solving the problem> The present invention is a horizontally placed cylindrical high-pressure tank, in which the opening/closing operation is performed from the inside at the lower part of the side wall, which is at least below the outermost diameter position, which is the horizontal span of the tank body. In addition to installing a small escape door,
An escape groove with a width for one person to crawl in is constructed along the longitudinal direction of the tank body on the installation floor surface closer to the tank than on the perpendicular line of the outermost diameter side wall facing the diagonally downward facing escape door. , and a fisheye lens type observation window is attached from the inside to at least the wall surface of the tank body on the side of the operation panel, and a presence indicator lamp that can be operated from the inside is arranged on the outer surface of the tank body.

<Function> Due to the above configuration, when a person (patient, etc.) in the high-pressure tank is in a building collapsed due to an earthquake, or the pressure is not operating normally (for example, a technical staff member suddenly falls ill and is unable to operate the tank), You must escape from the tank. However, if you suddenly go from a pressurized state to atmospheric pressure, you will suffer from decompression sickness, so operate the emergency depressurization operation part provided in the tank and open the escape door after depressurizing in sequence. That is, first, after shutting off the air supply port, an emergency tank for reducing the pressure is opened, and since the pressure must be reduced over a predetermined time in this case, a safety confirmation timer is also set. The escape door opens only when the pressure inside the tank reaches a value close to or equal to atmospheric pressure after a certain period of time.

During this escape, even if the ceiling, walls, etc. fall onto the tank body and are in front of the escape door position, the escape door will be directly blocked because the escape door is hidden inside and below the tank's outermost diameter position. Moreover, since it is an inward-opening door, it can be opened and closed without any trouble, and it can immediately crawl into the escape groove in the installation floor, making it possible to escape from the building through the groove. In addition, if a presence indicator lamp that is operated from inside the tank body is turned on, even if the escape door cannot be opened, a third party will be aware of the presence of someone, which will be useful for early rescue. Of course, the viewing window is a fisheye lens type, so the field of view from inside the tank is expanded, allowing you to accurately grasp the situation outside the tank, which helps to reduce mental irritation.

<Example> Hereinafter, the present invention will be described in detail based on the drawings of the example.

Reference numeral 1 denotes a large high-pressure tank main body which is a second type device and is equipped with a main chamber 1a and an auxiliary chamber 1b.
A clutch door type escape door 2 that can be freely opened into the tank is attached to the lower part 1c' of the side wall forming a lower arc. Of course, in this case, the outlet 2a is hidden on the tank side from the perpendicular line b hanging down from the outermost diameter position a.
3 is a perpendicular line b to the outermost diameter position a on the outside of the escape door 2
The escape groove 3 is constructed in the installation floor part 4 which is located on the inner side, and is provided along the longitudinal direction of the tank body 1, and is exposed to the outside of the building A if necessary. This escape groove 3 is normally closed by a group of 5 lid bodies having an appropriate length, and forms a floor portion 4'. Further, in this cover body 5, scarf slopes 5a, 5a are arranged at the abutting ends of at least two cover bodies 5, 5, which are in the position of the escape door 2, so that the scarf slopes 5a, 5a are overlapped. 5 can easily ride on other lid bodies 5, making it easy to open the lid. Reference numeral 6 denotes an embedded type handle provided on the lid body 5. Reference numeral 7 denotes a fisheye lens-type observation window installed on the side wall 1c of the tank body 1 at least on the side where the operation panel B is located, which provides a field of view of about 180 degrees from inside the tank, and allows you to see whether there are people outside the tank and the situation in the room. It becomes. Reference numeral 8 denotes a presence indicator lamp installed in parallel with an in-use indicator lamp 10 provided near the entrance of a hanging door 9 located in front of the tank body 1; It is connected to a separate power source (not shown) such as a dry battery, and is turned on only in an emergency by turning on the switch 11 inside the tank. However, if necessary, a switching configuration may be used to use an external power source (power outages often occur during disasters such as earthquakes). 12 is an emergency operation unit for depressurization located inside the tank and located near the escape door 2;
The emergency operation unit 12 includes an air supply cutoff operation lever 15 that is linked to a cock 14 provided on the air pipe 13 of the piping below the tank floor 1d, and a pressure reduction lever 15 that is linked to a cock 16 for moving outside the tank. An operating lever 17 and a safety confirmation timer 18 that measures the opening time (depressurization time) of the pot 16 are incorporated. In the figure, reference numeral 19 denotes a hanging inner door installed in the passage section 1f that is the boundary between the main chamber 1a and the auxiliary chamber 1b. It is assumed that 1a and the subchamber 1b are in communication. 20
21 is an air conditioner, 21 is an ultraviolet ray/ozone generator for sterilizing and purifying the air inside the tank, 22 is an oxygen inhalation device with at least as many units as the number of people entering the room, 23 is a clutch-type work door that can be operated from outside the tank, and 24 is an A viewing window for viewing from the outside, 25 indicates an exhaust pipe.

To explain this effect, first of all, in the case of ordinary hyperbaric oxygen treatment for paralysis, arteriosclerosis, whiplash, rheumatism, post-surgery recovery, rehabilitation, etc., a technical staff operates operation panel B outside the tank and the compressor is activated. (not shown) to pressurize the inside of the tank (for example, cage pressure 0.8 to 0.9 atm).
This change in atmospheric pressure stimulates the blood, cerebrospinal fluid, etc. in the human body by changing the pressure, giving a kind of pine surge effect to organ tissue cells and improving pathological symptoms.

In this case, if an earthquake occurs and Building A collapses, causing the ceiling, walls, etc. to fall toward the tank, or if a technical staff member becomes unable to operate due to sudden illness or the like and has to make an emergency evacuation, the people inside the tank (patients, etc.) ) The user himself/herself sequentially operates the emergency operation section 12 for depressurization according to the instructions on the explanatory plate (not shown) here to reduce the pressure. First, the air supply cutoff operation lever 15 is pushed down (pull) to close the cock 14, which is a gate valve of the air supply pipe 13, via the interlocking mechanism 26, which is a link mechanism, so that the inside of the tank is no longer pressurized. Next, the pressure reduction operation lever 17 is pushed down, and the associated tank 16 attached to the tank wall is opened to reduce the pressure by emergency exhaust. However, in order to confirm the pressure reduction time at this time, a spring-type safety confirmation timer 18 that is movable even during a power outage is set, and the pressure is reduced over a certain period of time based on this display. Of course, this decompression time is about 1
It is set based on the opening diameter of 6. In addition, in special treatment under high pressure of 2 to 3 atmospheres, the decompression time is not set linearly as described above, but in stages.

After the tank internal pressure is reduced to atmospheric pressure or a value close to it, the escape door 2 is opened. In this case, since the illustrated escape door 2 adopts the clutch door method, the tightening ring portion 2b on the outer periphery is moved by rotation of the protruding lever 2c, and the escape door 2 is moved inward at the clutch disengaged position. Just open it. At this time, the exit 2a of the escape door 2
is facing the hidden position C formed by the arcuate wall surface that is inside the perpendicular line b of the outermost diameter position a of the tank body 1, so collapsed materials d such as fallen ceilings and walls have come around to the hidden position c. There is no blockage (see Figure 11). Therefore, escape from the escape door 2 is not hindered.

Thereafter, the user leans out of the exit 2a and partially shifts the lid 5 of the escape groove 3, which is normally closed, to open the lid. In this state, go down to the escape groove 3, crawl through the escape groove 3, and exit outside the tank installation or outside the building. Now, construct the direction to the outside of building A). In addition, a transparent part (not shown) for illumination may be arranged in a part of this lid body 5, or
It is possible to provide a guide lamp (not shown) inside the escape groove 3 that is lit by an emergency power source.

Additionally, in the event of such an emergency,
Turn on the emergency switch 11 inside the tank and turn on the presence indicator lamp 8 facing the outside of the tank.
Making it known that there are people inside the tank will lead to early rescue.

Furthermore, since the wall of the tank body 1 is equipped with a fisheye lens-type observation window 7 for viewing from inside, the situation outside the tank can be seen from a wide angle, which not only helps in deciding when to escape, but also provides mental relief. .

<Effects of the invention> As mentioned above, the emergency safety device for the therapeutic high-pressure tank of the present invention is such that the escape door is installed at the bottom of the side wall below the tank's outermost diameter position, and the escape door is installed near the escape door. By providing an escape groove on the floor and a fisheye lens type viewing window and occupancy indicator lamp on the tank surface, even if the building collapses due to an earthquake and the ceiling, walls, etc. fall toward the tank,
Since this escape door is located in a hidden position when viewed from above, which is below the outermost diameter of the tank, it is possible to open the door and escape.Moreover, in this case, the escape groove faces directly below the escape door, so it is possible to open the door and escape. All you have to do is dig the groove and get out. Of course, since the escape groove itself is constructed along the perpendicular position of the outermost diameter position of the tank body toward the tank, the groove itself will not be crushed. Furthermore, by disposing one or more presence indicator lamps on the outside of the tank, it is possible to see at a glance that there are people inside the tank, which leads to early rescue. In addition, a fisheye lens-type observation window with a wide-angle field of view is placed on the tank wall (especially on the control panel side), allowing you to get a maximum understanding of what's happening outside the tank, helping you decide when it's time to escape, and providing mental peace of mind based on wide-angle confirmation. also get Moreover, since the structure of the present invention is simplified, it does not cause malfunctions or breakdowns even when operated in an emergency (by an amateur), and has practical effects such as being durable for long-term use.

In addition, although the above description of the tank has been made regarding a type having a circular cross section, the same applies to a type having an elliptical cross section.
