せ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,
An example of an oxygen supply device that can easily replenish oxygen into the body for respiratory support and fatigue recovery is disclosed in Japanese Patent Application Laid-Open No. 61-222.
This is shown in Publication No. 906 and the like. In this method, sodium percarbonate, manganese monoxide, and water are separated and housed in a container by a partition wall, and when oxygen is generated, the partition wall is destroyed and the chemicals are mixed and reacted to chemically generate oxygen. It is designed to occur.

素の供給を行なうようにしたものがある。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.

以下で用いられる。(Problems to be Solved by the Invention) By the way, as described in JP-A-61-16724, 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 this can lead to health problems. Therefore, when using oxygen in medical care, pure oxygen is mixed and diluted with air to give an oxygen concentration of 50%.
Used below.

開口されている。Therefore, in both the oxygen supply device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 61-222906 and the oxygen supply device in which a low-pressure container is filled with oxygen, pure oxygen generated or discharged is diluted by mixing with air. An inhalation mask or mouthpiece, etc., through which pure oxygen is released into the body so as to be inhaled into the body, has a vent or an air introduction port that communicates with the outside air.

とができない。However, the mixing ratio of released pure oxygen and air varies greatly depending on the suction force and frequency of exhalation of the inhaler.
The desired dilution rate cannot always 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.
本発明は、上記のごとき事情に鑑みてなされたもので、
空気で所望の濃度まで混合稀釈された酸素が吐き出され

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.

過炭酸ナトリウムが水中で反応して酸素が発生される。Here, the chemical oxygen generator 6 will be briefly explained. For example, granular sodium percarbonate as a hydrogen peroxide derivative and manganese dioxide as a decomposition catalyst sealed in a water-soluble paper bag are stored in a resin container. A water injection hole is provided in the container and is usually closed with a stopper. Further, a breathable and water-impermeable membrane is provided to cover the oxygen outlet 6a. The chemical oxygen generator 6 has such a configuration, and when generating oxygen, a predetermined amount of water is poured into the container from the water injection hole. Then, the water-soluble paper bag containing manganese dioxide dissolves, and the manganese dioxide and sodium percarbonate react in the water, producing oxygen.

。In this configuration, when replenishing insufficient oxygen in the body, water is poured into the chemical oxygen generator 6, the chemical oxygen generator 6 is attached to the main body case 1, and the control switch is operated to rotate the motor 2. Then, due to the rotation of the axial fan 3, air flows into the intake port 5.
It is sucked in from the air and then discharged from the discharge port 4. Here, since one end of the ventilation path 7 is open lower 1 in the center of the discharge port 4, a fast air flow flows around this opening.

た酸素を手軽に補充できる。Therefore, due to the ejector effect, a negative pressure is created just before the open lower □, and the oxygen generated by the chemical oxygen generator 6 is sucked out from the open lower via the ventilation passage 7 and mixed with the surrounding air flow. Ru. During this time, turbulence also occurs in the air flow around the lower a, and oxygen is mixed and diffused. Here, if the rotational speed of the axial fan 3 is constant, the discharge air volume is almost constant, and the suction force due to the ejector effect is also constant. Furthermore, the amount of oxygen discharged from the chemical oxygen generator 6 per minute is also approximately constant. For this reason, the dilution rate of oxygen with air is approximately constant, and a predetermined concentration of oxygen is exhaled, making it possible to easily replenish oxygen shortages without causing any harm to health.

This will be explained with reference to the figures. FIG. 5 is a longitudinal cross-sectional view of another embodiment of the oxygen supply apparatus of the present invention, and FIG. 6 is a cross-sectional view of FIG. 5. 5 and 6, the same members as those in FIGS. 1 to 4 are given the same reference numerals, and redundant explanation will be omitted.

A plurality of small holes 21゜21-... are made in the narrowed part of 0,
The ventilation path 7 is opened to the Venturi tube 20 through the small holes 21, 21-.

確実に混合稀釈されて所定の濃度となる。In this configuration, air is sent into the Venturi tube 20 by the rotation of the axial fan 3, and the air is sent into the Venturi tube 20.
The flow rate becomes high at the narrowed portion of 0, and the oxygen in the air passage 7 is sucked out from the small holes 21, 21- by the Venturi effect. Therefore, by sucking out the oxygen, the oxygen is reliably mixed and diluted with air to reach a predetermined concentration.

うにしても良い。Note that the oxygen generator is not limited to the chemical oxygen generator 6 as in the above embodiment, but may be a low-pressure container compressed and filled with pure oxygen. The chemical oxygen generator 6 is not limited to the structure of the above embodiment, but may have any structure as long as it can appropriately chemically generate oxygen. Further, the oxygen generator may be inserted into the main case 1 from the back side of the main case 1, but it may also be inserted from the bottom, front, or side of the main case 1. Moreover, although the main body case l can be made thin by using the axial fan 3, a centrifugal fan, a mixed flow fan, or a cross-flow fan may be used instead of the axial fan 3. Furthermore, the axial fan 3 is configured to be able to be controlled by switching between low-speed rotation and high-speed rotation, and functions as an oxygen supply device by rotating the axial fan 3 at low speed while generating oxygen, without generating oxygen. The axial fan 3 may be rotated at high speed to function as an electric fan so that it can serve both purposes.
