Description

[Detailed Description of the Invention] The present invention relates to a compact and simple oxygen supplementer used during temporary oxygen deficiency conditions.

Immediately after exercise, a large amount of oxygen in the blood is consumed during exercise, so the oxygen concentration decreases, creating a state of oxygen deprivation, which delays recovery from fatigue and reduces exercise performance. Become.

Therefore, in order to quickly recover fatigue and exercise capacity, it is necessary to ingest a large amount of oxygen in a short period of time.

The first purpose of the present invention is to meet this need, by supplying oxygen-rich air containing a higher amount of oxygen than normal air into the breathing area during a temporary oxygen deficiency immediately after strenuous exercise, thereby quickly relieving fatigue. The goal is to allow athletes to recover and be fully active during games, practices, etc.

In addition, there are many people in Japan with heart disease, and in the event of an emergency caused by this disease, these people would traditionally use oxygen inhalers provided at hospitals, but these devices are expensive. It is impossible to keep this in a general household, and because of its large size, it is also impossible to carry it around, so it cannot be used immediately in an emergency.

The second purpose of the present invention is to compensate for the shortcomings of conventional oxygen inhalers used for the treatment of diseases, etc.; it is small and portable, is inexpensive, and provides supplemental oxygen. The purpose of the present invention is to provide a simple oxygen supply device that can automatically adjust the pressure of oxygen.

The structure of the simple oxygen supplementer of the present invention is that it is securely attached to a relatively small cylinder filled with oxygen, and includes a seal-breaking mechanism that breaks the seal of the cylinder and spouts out oxygen, and a mechanism that controls the flow rate of the jetted oxygen. The device is composed of a flow rate control mechanism and a mouth horn provided in an orifice from which oxygen whose flow rate is controlled by the flow rate control mechanism is ejected.This will be explained below according to an embodiment shown in the drawings.

In the figure, 1 is a cylinder filled with high-pressure oxygen, which is preferably 100 cc or less in consideration of portability.

Reference numeral 2 denotes a seal-breaking mechanism, which has a cylinder mounting part 3 that is securely screwed into a threaded part provided at the mouth of the cylinder 1 at the bottom and an oxygen flow hole 10 connected thereto, and a seal-breaking mechanism in the upper part. A screw punch 5 is provided for opening the sealing plate 4 of the cylinder 1 which has been sealed.

That is, the threaded punch 5 has a cutting arrow 6 at the lower end, a threaded part 7 at the middle part, an O-ring 8 at the upper part, and a knob 9 at the upper end.
It has a arrow 6 which moves downward by rotating it.
A hole is made in the sealing plate 4, and an O-ring 8 is used to prevent oxygen from flowing out.

Reference numeral 11 denotes a flow rate control mechanism for always keeping the flow rate of oxygen constant. The opening diameter on the gas reservoir portion 19 side is made larger than the portion closer to the oxygen flow hole 10, and a valve seat 14 whose peripheral edge protrudes into the valve chamber is provided at the end closer to the flow hole 10. A valve seat hole 13 is provided at the center of the valve seat 14, and an orifice 18 is provided between the gas reservoir 19 and the center of the mouthpiece horn 20. is formed.

On the other hand, the piston 12 housed in the valve chamber has a T-shaped cross section that roughly matches the shape of the valve chamber, and has a larger diameter on the outflow side (gas reservoir 19 side) than on the oxygen inflow side. , is loosely fitted in the valve chamber so as to be able to move in the left and right direction, and a split groove is formed on the end surface of the tip end on the valve seat 13 side, which is continuous in the diametrical direction and whose both ends reach the inner wall surface of the valve chamber. At the same time, a valve body 17 which has a smaller diameter than the end face of the tip end of the piston 12 so as not to contact the inner wall surface of the valve chamber and has a larger diameter than the valve seat hole 13 straddles the above-mentioned split groove and is attached to the tip end of the piston 12. The valve seat 14 is mounted integrally.
In addition, a gas passage 15 is formed in the center of the piston 12 to communicate from the valve seat hole 13 to the gas reservoir 19 side via the groove.

Reference numeral 16 denotes a spring, which constantly urges the piston 12 in the direction of the gas reservoir 19.

Furthermore, a mouthpiece horn 20 is shaped like a bottomless bowl and has an end circumference that fits closely around the human mouth, and is attached to the circumference of the orifice 18.

Next, the method of use and operation of this embodiment will be explained.

First, attach the cylinder 1 filled with high-pressure oxygen to the cylinder mounting part 3 in a secure manner, and then turn the knob 9 to remove the cut arrow 6.
Gradually lower the button so that it pierces the sealing plate 4, and then turn the knob 9.
Rotate it in the opposite direction and return it to its original position.

As a result, the sealing plate 4 is opened, and the communication hole 10 is opened from the opening.
High pressure oxygen is injected inside.

At this time, since the O-ring 8 is provided on the knob 9, high-pressure oxygen will not leak from the local area where the knob 9 is attached.

The high-pressure oxygen ejected into the communication hole 10 further flows into the flow rate control mechanism 11 from the valve seat hole 13.

In the flow control mechanism 11, high pressure oxygen is supplied to the piston 1.
The gas passes through the flow path 15 provided in the gas reservoir 2 and reaches the gas reservoir 19, and the pressure in the gas reservoir 19 increases.

At this time, the diameter of the piston 12 on the gas reservoir 19 side is larger than the diameter on the flow hole 10 side, and therefore the surface area is also larger. Therefore, if the pressure per unit area is the same, the gas reservoir 19 has a larger surface area. When the compression force from the side exceeds the compression force from the communication hole 10 side and further overcomes the compression force from the spring 16, the piston 12 moves toward the communication hole 10 side, and the valve integrally provided at the tip of the piston 12 moves to the communication hole 10 side. Body 17 is valve seat 1
4 and closes the valve seat hole 13 to temporarily stop the flow of high pressure oxygen into the high pressure oxygen flow rate control mechanism.

During this time, the high-pressure oxygen on the side of the gas reservoir 19 is sequentially flowing out from the orifice 18, and the pressure within the gas reservoir 19 gradually decreases accordingly.

Then, the pressure inside this gas reservoir 19 decreases and the piston 1
When the compressive force against 2 is lost to the biasing force of the spring 16, the piston 12 moves toward the gas reservoir 19 side due to the biasing force of the spring 16, and at the same time, the valve element 17 is released from the valve seat 14, so that the piston 12 is moved again to the valve seat hole. The section 13 is opened to allow high pressure oxygen to flow into the flow control mechanism 11.

When the pressure inside the gas reservoir 19 becomes high, the above-described operation is repeated to control the oxygen pressure and discharge oxygen at a constant pressure into the mouthpiece horn.

Note that if an extremely small hole is made in the cylinder sealing plate 4 with the arrow 6, the flow rate of oxygen will be extremely small, and the blowout of oxygen can be prevented by pressing the tip of the arrow 6 against the opened hole. It is also possible to stop the flow and control the flow rate.

As explained above, the present invention has a small overall shape, which makes it portable, and therefore can be used for outdoor sports, such as mountain climbing, to compensate for the lack of oxygen caused by a drop in atmospheric pressure, and can also be used in intense fields. In competitions, it is possible to prepare multiple units in the waiting area and use them when changing players to speed up recovery from fatigue.

In addition, the present invention has an extremely simple structure and can be manufactured at a low cost, so it can be kept in regular households, and people with heart disease, respiratory disease, etc. should keep it on hand in case of emergency. In addition, the present invention is not only less likely to malfunction due to its simple configuration, but also can automatically adjust the pressure of supplementary oxygen, thus replacing conventional oxygen inhalers. Therefore, there is no risk of an accident occurring due to sudden jetting out of oxygen due to failure of the control mechanism.

Furthermore, it can also be used as an evacuation tool in the event of a fire.
