Gas mask for inhalation.

Conventionally, a portable gas supply device has been known as a device for easily inhaling oxygen. This portable gas supply device is a small gas container (gas cartridge) that is compressed and filled with oxygen or oxygen-enriched gas as an inhalation gas. For example, if a person suffers from heart disease, an asthma attack, or a breathing difficulty such as a traffic accident. It is used to administer oxygen during first aid treatment when it occurs, and in recent years, it has also been widely used to recover fatigue from exercise and the like. In order to effectively inhale and administer oxygen, a gas inhalation mask having a shape that covers the mouth and nose of the inhaler is connected to the gas discharge part of the gas cartridge or via a hose. Connection is also performed (for example, refer to Patent Document 1). In addition, in consideration of the storability, there are some cases where the shape of the gas inhalation mask also serves as the cap of the gas cartridge, but it is not suitable as the shape of the gas inhalation mask, and the inhalation efficiency becomes low.

It has a discharge nozzle 13.

The gas inhalation mask 15 shows the first embodiment of the gas inhalation mask of the present invention, and is made of a material having flexibility as a whole, for example, a material that hardly allows passage of gas such as polyvinyl chloride, silicon and latex. Is formed of. A tubular base-side connecting portion 16 connected to the discharge nozzle 13 is provided on the mask base side of the gas suction mask 15. By fitting and connecting the discharge nozzle 13 to the base-side connecting portion 16, the gas suction mask 15 is attached to the gas cartridge 12. Further, on the mask tip side of the gas inhalation mask 15, there is provided an inhalation shape portion 17 whose tip edge covers the mouth and nose of the inhaler and abuts on the face, and the inhalation shape portion 17 and the base portion side. The connecting portion 16 is connected by a conical expanding portion 18 that gradually increases in diameter toward the suction shape portion 17.

Further, a small-diameter hollow peripheral gas introduction portion 19 is provided at the peripheral edge of the front end side opening portion 15a of the gas suction mask 15. The peripheral gas introducing portion 19 is expanded by the introduction of the suction gas discharged from the discharge nozzle 13 into the peripheral shape of the suction shape portion 17, and can be contracted when the suction gas is not introduced. The portable gas supply device 11 is formed so as to be foldable, and can be folded or wound around the outer periphery of the gas cartridge 12 before the portable gas supply device 11 is used.
