Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an oxygen inhalation mask, and in particular, an oxygen inhalation mask provided with an oxygen dilution mechanism used in an oxygen inhaler for health promotion, which has recently received attention. Regarding

[Conventional technology]

Medical and oxygen inhalers have been widely used, but in recent years,
Since inhaling oxygen has an effect on stress relief and fatigue recovery, an oxygen inhaler for health promotion has been developed.

However, the masks for inhalation used in these oxygen inhalers for health promotion have been diverted from conventional medical masks, and most of these medical masks have a diluting mechanism that controls the oxygen concentration. It was provided on the body side of.

Further, in the case where the diluting mechanism is provided on the mask side, a cover is rotatably provided at the oxygen supply tube connection side end of the inhalation mask, and windows formed at the end of the cover and the inhalation mask, respectively, By rotating the cover, the opening degree was adjusted to adjust the amount of air introduced into the inhalation mask.

[Problems to be solved by the device]

Therefore, when the oxygen concentration is adjusted, the opening degree is set in advance, which is troublesome to handle.

Therefore, an object of the present invention is to provide an oxygen inhalation mask capable of adjusting the oxygen concentration while holding the mask with one hand.

[Means for Solving the Problems]

In order to achieve the above object, the oxygen inhalation mask of the present invention is an oxygen inhalation mask comprising a grip portion and a mask portion communicating with the grip portion, and the grip portion has an inside thereof as the mask portion. The oxygen concentration passage is formed by partitioning the concentrated oxygen passage communicating with the atmosphere introducing chamber with a partition wall to form an air passage in the partition wall and sliding the slider to open and close the air passage. It is characterized in that a lever for operating the slider is connected to the slider by projecting an end portion thereof to the outside of the grip portion.

[Action]

With this configuration, the lever can be operated while the grip portion is held with one hand, and the air passage between the concentrated oxygen passage and the atmosphere introducing chamber can be opened and closed with the slider, so that the oxygen concentration can be controlled.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

The oxygen inhalation mask 1 comprises a synthetic resin mask portion 2 and a grip portion 3, and the mask portion 2 integrally includes a cover portion 2a for covering the periphery of the mouth and nose and a nozzle portion 2b continuous to the lower portion thereof. Is forming.

As shown in FIG. 2, the grip portion 3 is a flat hollow body and is bent about 30 degrees toward the back side of the mask near the upper end thereof, the mask portion 2 is connected to the upper end thereof, and the lower end is concentrated. A connector 5 to which the oxygen supply tube 4 is connected is formed.

The mask portion 2 and the grip portion 3 are the nozzle portion of the mask portion 2.
A positioning protrusion 3a formed inside the upper end of the grip portion 3 is fitted and connected to a groove 2c formed at the lower end of the grip 2b.

The inside of the grip portion 3 is provided with an inverted L-shaped partition wall 6,6 at the bottom and is divided into three parts in the vertical direction. The center sandwiched between the partition walls 6,6 is the mask part 2 and the connector 5. A concentrated oxygen passage 7 that communicates with each other, and both sides thereof are respectively formed in an atmosphere introducing chamber 9 having an atmosphere introducing hole 8 at a lower end.

Further, the upper portion of the concentrated oxygen passage 7 spreads over the entire inside of the grip portion 3 and also serves as a mixing chamber for the concentrated oxygen and the atmosphere.

The partition walls 6, 6 have a concentrated oxygen passage 7 and an atmosphere introduction chamber 9
Slits 10 and 11 are provided as air passages that communicate with and. The ventilation passage may have a hole shape.

Further, inside the partition walls 6, 6, a slider 12 is provided slidably in the vertical direction.

The slider 12 has left and right side walls 12a and 12b whose upper parts slide inside the upper side walls of the concentrated oxygen passage 7 and whose lower parts slide inside the partition walls 6 and 6, respectively.
The upper portions of a and 12b are connected by a connecting member 12c, and the lower portions thereof are connected by a connecting member 12d, so that they are formed in a substantially inverted eight shape.

Further, convex portions 12e, 12e that fit into the slits 10, 10, 11, 11 are formed at the lower ends of both side walls 12a, 12b of the slider 12.

A lever 14 is connected to an upper portion of the slider 12 so as to project to the outside of the grip portion 3 from a longitudinal elongated hole 13 formed in an upper portion of a side wall of the grip portion 3. The lever 14 projects from the lever 14. The outer surface is provided with a scale 15 that indicates the amount of slide of the slider 12.

The operation of the oxygen inhalation mask 1 configured as described above will be described. The concentrated oxygen supplied from the supply tube 4 connected to the connector 5 passes from the nozzle 2b of the mask 2 through the concentrated oxygen passage 7. Gush out.

At this time, if the lever 14 is lowered to the lowest scale 15, the convex portions 12e, 12e of the slider 12 are aligned with the lower slits 10, 10 formed in the partition walls 6, 6 of the concentrated oxygen passage 7. Mating,
Since the slits 10 and 10 and the upper slits 11 and 11 are closed to prevent the atmosphere from flowing into the concentrated oxygen passage 7 from the atmosphere introducing chambers 9 and 9, the concentrated oxygen supplied from the supply tube 4 is sucked as it is. To be done.

Next, raise the lever 14 to the middle graduation 15 and slide
12 slides upward, and the convex portions 12e, 12e at the lower end are the upper slits 11, 12 formed on the partition walls 6, 6 of the concentrated oxygen passage 7.
Since the slits 10 and 10 are fitted into the chamber 11 and the slits 10 and 10 are opened, the atmosphere flows from the atmosphere introduction chambers 9 and 9 into the concentrated oxygen passage 7 and is mixed with the concentrated oxygen supplied from the supply tube 4 to remove the concentrated oxygen. Dilute.

Further, when the lever 14 is raised to the upper scale 15, the slits 10, 10, 11, formed on the partition walls 6, 6 of the concentrated oxygen passage 7
11 is opened, and the atmosphere from the atmosphere introducing chambers 9, 9 flows into the concentrated oxygen passage 7 more than the above, and is mixed with the concentrated oxygen supplied from the supply tube 4 to further dilute the concentrated oxygen.

Therefore, the concentration of the concentrated oxygen sucked from the mask portion 2 can be controlled to be diluted by moving the lever 14 up and down while holding the grip portion 3, so that it can be easily operated with one hand.

[Effect of device]

As described above, the oxygen inhalation mask of the present invention has, in the grip portion of the inhalation mask, the concentrated oxygen passage communicating with the mask portion and the atmosphere introducing chamber communicating with the concentrated oxygen passage through the ventilation passage. At the same time, since a slider for opening and closing the air passage is provided and the lever for operating the slider is projected to the outside of the grip portion, by operating the lever while holding the grip portion, the slider is moved to open the air passage. By opening and closing, the atmosphere flowing into the concentrated oxygen passage from the atmosphere introduction chamber is controlled, and the concentration of concentrated oxygen sucked from the mask part is diluted, so you can dilute the oxygen concentration with the mask part on your face. Easy to operate with one hand.
