Aug. 21, 1962 W. ULMER SECRETION SUCTION DEVICE FOR RESCUE APPARATUS Filed Sept. 19, 1960 INVENTOR Wolr'ya/ o (/[mer 4% E AT I O RNE '5 3,050,062 SECRETIQN SUCTION DEVICE FOR RESCUE APPARATUS Wolfgang Ulmer, Bochum, Germany, assignor to Otto Heinrich Drager, Lnbeck, Germany Filed Sept. 19, 1960, Ser. No. 56,997 Claims priority, application Germany Oct. 2, 1959 1 Claim. (Cl. 128-276) This invention relates to a secretion suction device for first aid rescue apparatus. in particular, the invention is directed to a device for removing fluid from the breathing passages of a stricken person.
With an unconscious or apparently dead person, it is of utmost importance that the first aid worker trying to revive the person be able to suck free as quickly as possible the mucus, blood or water blocking the breathing passages of the person. In a hospital, large electrically driven pumps are used for such purpose. Also, ambulances and the like can use the power of the vehicle motor for this purpose. In addition, foot operated suction pumps are known. However, the hospital apparatus and a rescue vehicle apparatus can hardly be considered direct first aid. The disadvantage of using a foot operated suction pump lies in that it is substantially impossible for one first aid worker to operate a foot pump while bending over the stricken person lying on the ground.
The object of this invention is to produce a simple suction device which can be effectively used by a first aid worker.
In general, this and other objects of the invention are obtained by providing a fluid collection vessel composed of glass, plastic, or the like to which is attached a suction tube for insertion into the mouth of a stricken person in order to suck out mucus, blood or water from the breathing passages of the person. The collection vessel is also provided with a short neck to which is attached a mouthpiece composed of rubber or plastic. This mouthpiece has a collar which is grasped between the lips and teeth of the rescue worker. Consequently, the rescue worker can produce a partial vacuum within the fluid collection vessel by means of working his cheek muscles. This partial vacuum is suflicient to draw the fluids through the suction tube from the respiratory passages of the person and into the collection vessel. By reason of this structure, a rescue worker kneeling on the ground and bending over the head of the stricken person can remove the fluids from the respiratory passages of the person and leaves his hands free from holding the collection Patented Aug. 21, 1962 vessel and does not need a hand or a foot to produce the required partial vacuum.
The means by which the objects of the invention are obtained are described more fully with reference to the accompanying schematic drawing showing the device and its manner of use.
To the collection vessel 1 is connected a flexible suction tube 2 composed of rubber or the like. On the opposite side of the vessel is a short neck 3 to which is fitted a mouthpiece 4. This mouthpiece is provided with a flange 5 so that the mouthpiece can be held between the lips and the teeth of the rescue worker. As shown in the drawing, flange 5 has an outer diameter large enough sothat the flange extends over at least the exposed surfaces of the teeth and thus presents suiiicient surface area so that the lips can hold the flange against the teeth. A small rib 5a surrounding the outlet end of mouthpiece 4 is engageable by the teeth to prevent the mouthpiece from accidentally slipping from the mouth when the vessel 1 is being loosely held by the mouthpiece.
In use, the rescue worker bending over a prostrate stricken person can use his hands to open the persons mouth and insert tube 2 into the throat. Then after grasping the mouthpiece and by flexing his cheecks or slightly inhaling, the rescue Worker can produce a partial vacuum in vessel 1 and thus suck the fluids from the air passages of the stricken person into vessel 1.
Having now described the means by which the objects of the invention are obtained, I claim:
A device for the removal by suction of fluid matter from the respiratory passages of a stricken person comprising a fluid matter collecting vessel, catheter tube means attached to said vessel for insertion into the respiratory passages of said person, neck means joined to said vessel, a mouthpiece fastened directly to said neck means, a flange having a diameter large enough to extend over the teeth and secured to said mouthpiece for insertion between the lips and teeth of a rescue worker for holding said vessel by the lips and teeth while causing a partial vacuum in said vessel by mouth produced suction through said mouthpiece, and a small rib surrounding the outlet end of said mouthpiece.
