Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a gas that can quickly evacuate a patient to a safe place with less manpower, has extremely good cushioning properties, and does not cause pain to the patient. Concerning a fillable life stretcher.

Conventional technology Traditionally, when a fire or other emergency situation occurs in a hospital, etc.,
Stretchers and stretchers have been used to quickly evacuate bedridden patients, people with leg problems, patients who are unable to wake up after surgery, etc. to a safe location.

A stretcher consists of a cloth floor on which the patient lies, with handles attached to the four corners, and a stretcher has legs with wheels (sometimes foldable) attached to the bottom of the floor.

Problems that the invention aims to solve When a fire breaks out in a hospital, evacuation is started immediately, but patients who are unable to get up require assistance from guide personnel to escape. The victim is placed on a stretcher or wheelchair and hurried to the designated evacuation exit.

These evacuation exits include elevators, stairs, and (where installed) escape chutes.

However, conventional evacuation equipment and evacuation exits have many problems, making it extremely difficult to escape in the event of a fire or earthquake.
There was a strong demand for a solution to this problem, as it directly affects human lives.

In other words, regarding evacuation equipment: Since a patient who cannot walk is being transported, the entire weight of the patient and the entire weight of the evacuation equipment must be supported, which requires a large number of manpower, and generally attendants and nurses are not required. Because she is a woman, it takes three or four people to evacuate -100 patients, but due to the lack of manpower, it takes a considerable amount of time to evacuate all the patients, and it is too late. There are also many.

Because the overall length of evacuation equipment is long and safety measures are not taken, stretchers and stretchers are likely to hit walls, etc. If they hit hard, the shock will be directly transmitted to the patient, causing pain and anxiety, and in worse cases. Situations may also occur that end in injury to the patient.

Therefore, they have to be very careful about this, and the evacuation speed is slow.

When going down the stairs, you have to pay close attention to your footing, and because the evacuation equipment is long, you often end up hitting a wall etc. in a hurry, and it is very difficult to turn around at a high point. It's difficult and time consuming.

In particular, stretchers have wheels that cause them to slip unexpectedly, and the wheels are a nuisance.Furthermore, the weight of the entire stretcher makes it extremely difficult to handle, and the guides themselves are placed in an extremely dangerous situation.

In addition, conventional evacuation equipment is large and has a fixed shape, and cannot be folded in the longitudinal direction, so it takes up space when stored during normal times and is difficult to take out, making it difficult to keep it on hand. It can also be dangerous.

Regarding evacuation exits: People evacuating in a panic rush to evacuation exits such as elevators, stairs, and escape chutes, creating a bottleneck problem and creating a dangerous situation where the back is clogged. However, when this is combined with a stretcher or stretcher that takes up a lot of space, it becomes impossible to move at all.

Especially in elevators, there are one or two stretchers or stretchers.
I can only carry a stand.

Furthermore, in Japan, the cost of land is extremely high, so there are only a limited number of places equipped with emergency stairs, slides, escape chutes, etc., which means that people are concentrated in these areas, and patients are removed from stretchers and stretchers. This can only be done without doing the double and time-consuming work of transferring.

The present invention aims to solve all of the many problems mentioned above.

Means for Solving the Problems Therefore, the present invention constructs a floor on which a human body lies and a wall surrounding the floor with a gas-filled bag in a boat shape and foldable, and ventilates the floor and wall bags. Provide a gas inlet,
This gas-filled life-saving stretcher was constructed by connecting a gas filling device to the air inlet, attaching a belt to the floor or wall for fixing the human body, and attaching a handle and a towing rope to arbitrary positions in the front and rear directions of the boat-shaped body.

For this reason, when the filling device is activated, gas immediately fills the floor on which the human body is placed and the walls surrounding the floor through the gas inlet, and the whole body expands into a boat shape to form a stretcher.

After this, the patient is placed on the floor and secured with a belt.

The bags on the floor and walls are essentially air cushions, so they have very good cushioning properties, and the air cushions on the floor can absorb shocks from rough places, such as stairs. The air cushion can cushion the impact received when hitting a wall at a corner, so it can be handled roughly without worrying too much about the impact on the patient.

At this time, the patient's body is secured with belts on the floor or wall, so the patient is safe from shock and can be left with peace of mind during evacuation.

In this way, it has excellent impact resistance, supports the entire weight of the patient, is extremely lightweight, and has a smooth floor surface, so it can be easily attached to a handle or traction lobe at any location in the front and rear directions. In other words, even a single woman can easily evacuate patients.

In addition, the stairs are advantageous as an evacuation route in this case, and as mentioned above, you can just drag them down without any hesitation.
Also, since it is easy to change directions, you can smoothly evacuate one after another without getting stuck in the middle of stairs or in a jumping area.

Alternatively, when using the escape chute, the patient may be inserted into the escape chute with the stretcher of the present invention intact, and the patient may be slid down the chute along with the patient.

In other words, no matter which escape route you take, you will be able to quickly and safely escape with a very small number of people from the bed all the way to a safe place.

In this way, all evacuation operations proceed smoothly, quickly and safely, eliminating bottlenecks when using large evacuation equipment such as stretchers, and drastically reducing the number of victims caught up in fires, etc. It is possible to do so.

Since the gas-filled life-saving stretcher of the present invention is foldable, it can usually be folded mainly in its longitudinal direction and stored in a small size.

Embodiments Next, embodiments of the present invention will be described based on the drawings, but the present invention is not particularly limited to these embodiments.

First embodiment Figure 1 is a perspective view of the first embodiment, Figure 2 is a sectional view of the same embodiment, Figure 3 is a bottom view of the same embodiment, and Figures 4 (a) and (b) are in use. It is an explanatory diagram.

The overall shape is boat-shaped, and the floor air chamber 2 in which the patient A lies and the main air chamber 1 surrounding the floor air chamber 2 are made of a gas-filled rubber bag, and the bottom of the whole is made of rubber. A sliding plate 3 is provided, five guides 4 in the longitudinal direction are formed on the back side of the sliding plate 3, and the guide 4 is provided with notches 40 at three places so that the entire boat shape can be folded into four in the longitudinal direction.

Further, a gas blowing port for ventilating the floor air chamber 2 and the main air chamber 1 is provided, a filling device 7 is connected to the blowing port, and the filling device 7 is installed on the front upper surface of the sliding plate 3, The filling device 7 is filled with compressed gas (a gas made by mixing carbon dioxide gas and nitrogen gas at a weight ratio of 95:5), and the operating pin 7
1 and a safety pin 70.

A belt 5 for fixing the patient A while lying down is attached to the floor air chamber 2 at three points that contact the chest, abdomen, and legs of the patient A, and the belt 5 is fixed using a hook-and-loop fastener in the center. It is made detachable with a tool 50.

Also, a handle 3 is large enough to fit a hand into the front and rear ends of the sliding plate 3.
0 is opened, and holes 31 are opened on both sides of the hole 3.
A pulling lobe 6 is attached to the rope 1, and the ends of the two ropes 6 are fixed together to a handle 60.

Now, to explain the usage and operation of this embodiment, take out the folded embodiment from the storage location, pull out the safety pin 70 of the air bag w7, and then pull the operating pin 71 toward you. When this happens, gas immediately fills the air chamber 2 on the floor and the air chamber 1 on which patient A lies, rapidly from the inflatable bag w7 through the gas inlet, and the entire body rapidly expands into a boat shape, forming a gas-filled stretcher. .

Then, patient A is placed on the floor air chamber 2, and the belt 5 is
is fixed with a fixture 50. Since the fixture 50 is a hook-and-loop fastener, this work can be done quickly and without error.

If you cover Patient A's head with a blanket, etc. that you use in bed, you will not be able to cool down while taking shelter, and you will be protected from sparks and falling objects.

Then, since both the bag in the floor air chamber 2 and the bag in the main air chamber 1, which is the wall, are air cushions, the air cushion 9 in the floor air chamber 2 can absorb the shock received from the floor surface during transfer. In addition, the air chamber 1 becomes a wall of air cushion, which can reduce the impact of hitting the stretcher against a corner wall during transportation, so there is no need to be careful about this point. For evacuation image B, all you have to do is concentrate on how quickly you can escape.

At this time, the patient A's body is fixed by the three belts 5 of the floor air chamber 2, so the patient A is safe from the moving Noyok and can be left to the evacuation image B with peace of mind.

In this way, the rubber air chamber 1.2 filled with gas has excellent impact resistance and is extremely lightweight as a whole, so if you pull the handle 30 in the direction of travel or the handle 60 of the towing rope 6, Even if evacuation worker B is a woman, she can easily evacuate patient A by herself, and the sliding plate 3 has low friction and is easy to slip, and the guide 4 on the back side contributes to the directional stability of this stretcher. (See FIG. 4(a)).

As an evacuation route at this time, you can make full use of Stairs C and drag the stretcher down without any hesitation, and it is easy to change direction at the venue, etc., so that you can avoid getting stuck behind.
They were evacuated smoothly one after another.

In FIG. 4(b), of the two evacuation personnel B, the leading one holds the handle 30 and keeps the main stretcher afloat, while the second auxiliary person B holds the handle 60 of the robe 6. , adjusting the speed at which the stretcher slides down stairs C.

In this example, after use, the gas is removed and the air chamber is removed. .

Check for any damage to the second grade, replace the air filling device 7 with a new one, and fold the whole boat shape into four in the longitudinal direction from the notch 40 of the guide 4 and store it in preparation for next time use. It is.

Second Embodiment FIG. 5 is a perspective view of the second practical feeding, and FIG. 6 is a side view of the second embodiment.

The configuration of this embodiment is almost the same as that of the first embodiment, but the boat-shaped main air chamber 1 and the floor air chamber 2 are made integrally, the sliding plate 3 is not attached, and the bottom of the floor air chamber 2 is connected to the thick sole 32. Notches 33 for folding the thick sole 32 into four are provided at three locations to make only these portions thinner, and a mounting plate 8 is provided protruding from the outside of the boat shape at a position on the floor where the patient is to lie down. The mounting plate 8 is a gas-filled life-saving stretcher in which a handle 80 and a hole 81 are formed in the longitudinal direction of the boat shape, and two holes 81 are formed in each side direction.

In this embodiment, an awning 91 was further provided to cover the upper surface of the patient A, and the awning 91 was rolled up and stored in the cylindrical storage chamber 9 attached to the front part of the boat. , if necessary, and after covering the upper surface of patient A, fixing device 9
2, the awning 91 is fixed by being hooked onto the rear part of the boat, and when the fixing member 92 is removed, the awning 91 is rewound by the force of the spring inside the storage chamber 9.

The usage and effect of this embodiment are similar to those of the first embodiment, but since the thick sole 32 is not provided with the guide 4 of the first embodiment, the following measures may be taken. I can do it.

That is, the two rows 16 tied to the holes 81 of the mounting plate 8 at the rear of the boat are passed parallel to each other under the thick sole 32, and then passed through the holes in the handle 80 of the front mounting plate 8. When pulled, the lobe 6 passed under the thick sole 32 acts as the guide 4 of the first embodiment.

Therefore, in this embodiment, the row 1 passing under the thick sole 32 is
It is also preferable to form a stopper metal A for once fixing 6 at a required location on the mounting plate 8 or the like.

In addition, the rope 6 is not only passed through the rear lobe forward, but also passed through the front lobe 6 backward, and using four parallel ropes 6 as guides, both ropes 6 are pulled forward and backward. It is also possible to use it like this.

The four holes 81 provided on both sides of the boat shape in this embodiment are as follows:
This is important when this embodiment is to be lowered by a crane or the like on a rope. This is because such a situation may actually occur.

Also, the tent 9! By pulling this out, you can prevent sparks from a fire from falling on Patient A, and you can prevent falling objects from hitting Patient A in the event of an earthquake.

Incidentally, the awning 91 may be provided with a transparent window or may be entirely made of a transparent material.

In addition to this, it is possible to use various defensive measures in combination.

Now, the present invention is not limited only to the embodiments described above.

For example, in addition to the rubber mentioned above, cloth-lined rubber can be used for the boat-shaped material, or vinyl resin can be used in combination with the material, and since it is preferable to use a material with good slippage for the ground contact area, hollow silicon powder can be used. It is possible to use rubber materials mixed with

If each of the air chambers 1 and 2 has a double structure, the impact resistance performance will be greatly improved.

Using helium as the filling gas will greatly help reduce the overall weight.

The filling method of the present invention does not require the use of the filling device 7 as described above, but includes means for filling from a gas cylinder provided separately from the main body, a manual pump, a gas pipe installed in the hospital room, etc. It is also possible to adopt

Incidentally, when storing the present invention, it is also preferable to store emergency equipment such as so-called first aid, a water bottle, a dry towel, a towel, etc. together.

In addition to the effects of the invention, the present invention provides a structure in which the floor on which a human body lies and the wall surrounding the floor are configured with a gas-filled bag in the shape of a boat and can be folded freely, and a gas inlet is provided to ventilate the bag on the floor and wall. A gas-filled life-saving stretcher was constructed by connecting a gas inlet to the air inlet, attaching a belt to the floor or wall to secure the human body, and attaching a handle and a tow rope at arbitrary points in the front and rear directions of the boat-shaped body. Therefore, when the inflating device is activated, the entire body expands into a boat shape and becomes a stretcher.The air cushion on the floor can absorb the shock received from stairs, etc., and the air cushion on the wall can be applied to the wall at the corner. Because it can reduce the impact of an accidental collision, patients are safe against Shijibuku and can feel at ease during evacuation, while for evacuation personnel, it is extremely lightweight and requires no force. Even a single woman can easily evacuate a patient, and the present invention solves the problem of manpower shortages, enables quick and safe evacuation without delay, and cleverly eliminates bottlenecks when using large evacuation equipment such as stretchers. We have successfully solved this problem and drastically reduced the number of victims during disasters.

In addition, since the gas-filled life stretcher of the present invention is foldable, it can be folded in the longitudinal direction and stored in a small size, and an escape unit can be used.
It is also possible to move multiple units of the present invention by connecting them in series with ropes, and if the ventilation chamber is made high enough, it is also possible to stack them in an elevator, which will solve the social problem of an increase in the number of bedridden elderly in the near future. can also be adequately addressed.

Furthermore, the present invention exerts great power in places and areas where conventional stretchers cannot be used due to poor footing, such as in the mountains, in the snow, and in swamps.It also has buoyancy even at sea, so it can be used as a boat. This makes it a truly groundbreaking invention.
