本発明は、スポーツなどを行なつた直後の呼吸
補助や疲労回復のために、体内に酸素を豊富に供
給する酸素供給装置に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an oxygen supply device that supplies abundant oxygen to the body for breathing support and fatigue recovery immediately after sports or the like. .

るようにしたものである。(Prior Art) Immediately after engaging in strenuous sports such as tennis, marathons, aerobics, and mountain climbing, the body tends to lack oxygen. Therefore, for respiratory support and fatigue recovery,
An example of an oxygen supply device that can easily replenish oxygen into the body is disclosed in Japanese Patent Application Laid-Open No. 61-222906. In this method, sodium percarbonate, manganese dioxide, and water are separated and stored in a container by a partition wall, and when oxygen is generated, the partition wall is destroyed and the chemicals are mixed and reacted. It is designed to generate.

である。 Another example of an oxygen supply device is one in which a low-pressure container is compressed and filled with pure oxygen, and the compressed oxygen is gradually discharged to supply oxygen.

稀釈して酸素濃度50％以下で用いられる。(Problems to be Solved by the Invention) By the way, as described in Japanese Patent Application Laid-open No. 16724/1983, inhaling oxygen at a concentration close to 100% into the body for a long time can cause pneumonia symptoms, neurological disorders, etc. It is known that it can be harmful to health. Therefore, when oxygen is used medically, pure oxygen is mixed and diluted with air so that the oxygen concentration is 50% or less.

る。 Therefore, in either the oxygen supply device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 61-222906 or the oxygen supply device in which a low-pressure container is filled with oxygen, pure oxygen generated or discharged is mixed with air and diluted. An inhalation mask or a mouthpiece, etc., through which pure oxygen is released into the body, is provided with a vent or an air introduction port that communicates with the outside air so that pure oxygen is inhaled into the body.

の低い酸素しか吸入することができない。 However, the mixing ratio of pure oxygen and air to be released varies greatly depending on the suction force and frequency of exhalation of the inhaler, and a desired dilution ratio cannot necessarily be obtained. In other words, if the suction force of the inhaler's exhaled air is weak and infrequent, the inside of the inhaler mask or mouthpiece is likely to be filled with released pure oxygen, and the amount of air introduced from the outside air is small, resulting in a high concentration of oxygen. You will have to inhale oxygen. Also, given that the suction force of the inhaler's exhaled air is strong and frequent, the predetermined amount of pure oxygen is inhaled by the inhaler and introduced from the outside air before it is released into the inhaler mask or mouthpiece. There is a large amount of air flowing through the body, and only a low concentration of oxygen can be inhaled.

目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an oxygen supply device that discharges oxygen mixed and diluted with air to a desired concentration.

Then, the shutter 9 is set to "half open" and the control switch 5 is set to "low speed". Then, the oxygen generated by the chemical oxygen generator 7 and air from the intake port 8 are sucked by the centrifugal fan 3, and the mixed oxygen is sent to the discharge port 4.
Mixed and diluted oxygen is exhaled from. Here, the amount of air sucked from the intake port 8 is approximately constant depending on the ventilation area of the intake port 8 and the suction force of the centrifugal fan 3. Further, the amount of oxygen generated from the chemical oxygen generator 7 can be considered to be approximately constant. Therefore, the oxygen discharged from the discharge port 4 is diluted to approximately a predetermined concentration. Moreover, if the shutter 9 is set to a "fully open" state, the concentration of oxygen discharged from the discharge port 4 can be further reduced. Furthermore, if the shutter 9 is in the "fully closed" state,
It is also possible to discharge pure oxygen that is not diluted with air from the discharge port 4. Then, without injecting water into the chemical oxygen generator 7 to generate oxygen, the shutter 9 is fully opened, and the control switch 5 is turned on.
If it is set to "high speed", it can be used as a portable electric fan.
