Application January 11, 1954, Serial No. 403,246

6 Claims. (Cl. 12S-20S) This invention relates to a medical inhaling device and while more particularly intended to supply oxygen to persons afliicted with heart ailments, yet well adapted to supply other gaseous substances as may be required either for emergency uses or to benefit the organs of respiration.

In addition to being usable to advantage for the treatment of abnormal health conditions, the device is useful to supply a stimulating gas when required to invigorate the heart, as for example to pugilists between the rounds of a iight or to athletes on occasions when the heart is to be subjected to an unusual strain.

A more specific object is to provide a device of the above stated character which can more conveniently be carried about by travelers, for example, when on board airplanes, to stimulate heart action as may be required, or for the treatment of various respiratory ailments.

Another specific object is to provide, as a new article of manufacture, an improved rupturable capsule or sack for containing oxygen or any other medicinal gas for use in conjunction with a facial mask whenever an emergency may require.

Other objects, advantages and features of the invention will hereinafter appear.

Referring to the accompanying drawing, which illustrates a preferred embodiment of the invention,

Fig. l is a side elevation of the device showing the same in its operative position.

Fig. 2 is a front View of the device showing it positioned as in Fig. 1.

Fig. 3 is a longitudinal midsection of the collapsible container or jacket, showing within the same in elevation, a sack containing oxygen or other medicinal gas. In this view a fragment of the adjacent part of the mask is shown in section.

Fig. 4 is a section on line 4 4 of Fig. 3. In this view the jacket and gas containing sack are shown in full lines in a partly collapsed position, broken lines indicating the normal outline of the jacket or container, the sack being ruptured.

Fig. 5 is a fragmentary section showing on an enlarged scale the structure of the rupturable upper portion of the aforesaid sack. l

Fig. 6 is a side elevation showing, per se, the gas containing sack.

Referring in detail to the drawing, the elastic tubular container or jacket 7 provided by the device is shown associated with a facial mask 8 of gas tight sheet material, said mask having an apertured screwthreaded thickened wall portion 9 into which screws: the outer externally screwthreaded end portion 10 of said container, the mouth portion of said container communicating with said mask when the device is in use.

Said container 7 may be made of a rubberized plastic, the screwthreaded mouth portion thereof being iirm enough to carry dependable screw threads, but the remainder thereof being suiciently elastic to be readily collapsed, and resuming its normal position when the operator releases manual pressure therefrom.

Preparatory to putting the device into use a rupturable collapsible sack 12 containing oxygen or other medicinal gas is inserted into the container 7 through the mouth portion of the latter. This operation is facilitated by reason of the screwthreaded mouth portion of the container being of as great a diameter as the remaining portion thereof.

It is desirable that, when said sack is ruptured to discharge the contained gas therefrom into the mask the break in the sack occurring in the part of the latter which is adjacent to the mouth of the jacket 7. Therefore, as illustrated in detail in Fig. 5, the body portion of the sack 7 is provided at one end with an aperture 15, the portion of the sack thus apertured having externally adhered to it a patch 16 of thinner, less resistant sheet material than the sheet material of which the body portion of the sack is composed. Consequently, when the operator manually squeezes and collapses the jacket or container '7 he will cause the contained gas to rupture the sack adjacent to the mouth of the jacket 7 so that the oxygen Will be discharged through the apertured mask portion 9 directly into the part of the mask subjacent to the nostrils of the user.

The user of the device may provide himself or herself With a considerable number of the gas filled sacks 12. The container 7 may be quickly unscrewed from and screwed back onto the mask, because only a few coarse threads form the connection between the mask and container. When said container is detached from the mask a collapsed sack can be quickly removed from the container and a filled sack put in its place.

l claim:

1. In a device of the kind described, a manually graspable container having a mouth portion attached to a facial mask and communicating interiorly with said mask when the latter is being worn, and a gas iilled sack within said container occupying the greater portion of the space therewithin, said sack having adjacent to said mouth portion of said container a weakened wall portion and said container having an elastic wall portion which is manually compressible against said sack to rupture said weakened wall portion thereof.

2. The subject matter of claim l, and said weakened wall portion of said sack consisting of an apertured portion of the Wall of the sack and a patch of weaker sheet material than the remainder of the wall of the sack overlying said apertured portion.

3. In a device of the kind described, a manually graspable container having a mouth portion attached to` a facial mask and communicating interiorly with said mask when the latter is being worn, and a gas filled sack within said container occupying the greater portion of they space therewithin, said sack having adjacent to said mouth portion of said container a weakened wall portion and said container having an elastic wall portion at each of opposite sides of said sack, said wall portions being manually compressible against said sack between finger and thumb portions of a hand of the operator to rupture said weakened part of said sack and discharge gas therefrom into said mask.

4. The subject matter of claim 3, and said weakened wall portion of said sack consisting of an apertured portion of the wall of the sack and a patch of weaker sheet material than the remainder of the wall of the sack overlying said apertured portion.

As an article of manufacture, an elongated sack distended with a medicinal gas, said sack having a weakened end portion which ruptures when the sack is compressed.

6. The subject matter of claim 5 and said rupturable part of said sack comprising an apertured portion of the sacks wall and a patch of relatively thin material adhered to and overlying said apertured wall portion.
