Claims priority, application Sweden, Nov. 4, 1963, 12,100/ 63 1 Claim. (Cl. 128--145.7)
This invention relates to a device used for artificial respiration, and more particularly to a device which will be relatively small in size, light in weight and compact to such an extent as to make it readily portable and thus easily carried by an individual.
It is an object of the invention to provide means by which the person engaged in carrying the device can make it ready for quick use due to the ability of the compressible bag which forms the air pump of the device to restore itself to its normal form after compression. It is an object of the invention to provide an air pump in the device of such size and shape as to enable it to serve as a container for the mask, valves and hose connector, when such elements of the device are not being used, thus lending for the portability and compactness of the device.
It is an object of the invention to provide an air pump in the form of a compressible bag having an aperture normally receiving a filter and which aperture shall be of such size that various parts of the device may be entered through it for storage inside of the bag.
It is another object of the invention to provide a device of this kind which while in use will free the hands of the user, enabling him to hold the head of the person being treated to arrange for free passage of air through the windpipe to facilitate respiration. In such case the air bag or pump can be compressed between the elbow and ribs of the user of the device or perhaps between the foot and floor.
More particularly, the invention contemplates the provision of an air bag or pump in the form of a compressible bag provided with an air inlet valve. The bag has a large aperture or mouth in which a removable filter for vitiated air is fitted, said filter constituting a closure for said mouth. A hose, valves and a mask are attached to the filter. By the removal of the filter the hose, valves and mask can be placed inside of the bag and the filter replaced to close the mouth of the same and confine the parts above mentioned within the bag.
With these and other objects to be hereinafter set forth in View, I have devised the arrangement of parts to be described and more particularly pointed out in the claim appended hereto.
In the accompanying drawing, wherein an illustrative embodiment of the invention is disclosed,
FIG. 1 shows a respiration device constructed according to the present invention and in position for use, and
FIG. 2 shows the device in a position of non-use and in readiness for carrying.
Referring to the drawing, a respiration mask is shown at 1, the same being a so-called half mask which fits around the nose and mouth. At the opening or mouth in the mask is located an inhalation valve 2 and an exhalation valve 9, the housing containing the valves being connected by the flexible rubber hose 3 to a filter 4 for vitiated gas which is fitted in the mouth of a flexible rubber bag constituting an air pump, said bag being provided with an air inlet valve 6.
The filter 4 can be the type conventionally employed in ordinary gas masks. Said filter is fitted in the relatively large opening or mouth for the bag or pump 6 and forms a lid or closure therefor. The air pump, which thus consists of a soft, compressible bag has the non-return inlet valve 6 so that when the bag is compressed, it returns to its normal or expanded shape. Due to the resistance in the filter 4 it happens that the interior air space of the pump will not be exposed to the underpressure caused by the pump or bag when it expands. The air pump or bag is located in front of the filter in the direction of the air passage. If the pump was attached behind the filter 4 the underpressure would prove to be annoying due to the possibility of leakage of vitiated air into the device.
The mouth of the bag into which the filter 4 is fitted can be quickly closed around the filter by a resilient or other tension band or as quickly removed from it without involving the risk that the injured person is likely to be exposed to the inhalation of poisonous atmosphere.
When the device is not in active use, the bag or pump can be employed as a container or housing for the other parts of the device. That is to say, the filter 4, the hose 3 attached to it and the mask and valves at the end of the hose, can be detached from the bag and the filter placed back in the mouth of the bag in a reversed position so that it then locates the mask, hose and valves on the inside of the bag. The filter is held in its reversed position in the mouth of the bag by a tension band 10 and the aperture 7 constituting the intake of the filter 4 can be closed by a rubber stopper 8. A strap 11 can be attached for convenience in carrying the device while it is in the storage condition shown in FIG. 2. Such strap can be hung across the shoulder or it can be fastened to the belt even during the actual use of the device.
The pump may be operated by squeezing the bag and as herein stated that can even be done while both of the hands of the operator are free since it can be squeezed between the arm and body or squeezed between the foot and floor. If the injured person is able to breathe unaided a device made according to the invention and without the air pump is suitable for use as a gas mask as long as the user is in a vitiated atmosphere. If the injured person needs artificial respiration, the air pump or bag is Iattached as described for the pressure of air into his ungs.
The device can be used for artificial respiration in pure air, for example in cases of drowning at beaches or similar locations and in such cases it is not necessary to use a filter for vitiated air and only an inverse-shaped lid can be used.
Having thus described a single embodiment of the invention, it is obvious that the same is not. to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claim.
What I claim is:
A device for artificial respiration comprising, an air pump including a valved compressible bag having a large mouth, a closure for said mouth consisting of a filter for vitiated air, the filter being of a shape and size to conform to and close the mouth of the bag and to enable it to be fitted in the mouth with either of its opposite faces directed toward the interior of the bag, a. connecting device around the filter to thereby hold the filter in either of its two positions, a flexible tube carrying valves and a mask, attached to the filter and extending from one of the faces of the filter, the filter when fitted in one position, having the tube, valves and mask arranged to locate such elements on the outside of the bag in operative position to function when the bag is compressed, the bag being of a size to enable it to contain the filter, hose, valves and mask and serve as a protective enclosure therefor when the filter is positioned in the mouth of the bag so that said hose and attached valves and mask are disposed within the bag.
