Description:
BACKGROUND AND OBJECTS

It is conventional practice to employ mechanical apparatus for resuscitating non-breathing victims. This is normally carried out by applying a mask which is connected to an oxygen container. The mask must then be placed upon the face covering the nose and mouth. This method requires the use of both hands in order to effect and maintain an airtight seal around the face mask.

In aspirating a patient, a catheter is normally inserted into the throat of the patient in order to suction out fluids which clog the airway, thereby preventing positive resuscitation.

The resuscitating and aspirating processes are separate and apart from each other, requiring different apparatus, so that only one or the other may be employed at the same time.

This creates problems in actual usage since, if it is found necessary to aspirate a victim during the resuscitation operation, the resuscitation is stopped and the apparatus is replaced by the aspirating apparatus. When the aspirating problem is alleviated, the resuscitation operation is reinitiated. This procedure may be repeated several times, wasting valuable time and depriving the victim of oxygen at a critical time.

It is an object of this invention to provide combination resuscitating, aspirating and gastric draining apparatus which is of unitary construction, the resuscitating and aspirating portions thereof being operable either separately or simultaneously as desired.

Another object is to provide a combination resuscitating, aspirating and gastric draining device which is of simple, economic construction and may be readily and quickly applied to a patient by a person having knowledge of resuscitation procedures. The bi-lateral nasal pharyngeal tubes at the same time are ready for use by persons having knowledge of gastric drainage procedures.

A further object is to provide apparatus of the character described which permits resuscitating and aspirating functions to be carried out by means of a single device which is applied to the victim, and constantly remains in place while both resuscitating and aspirating.

A still further object is to provide a combination apparatus of the character described which includes an elongated body having a longitudinal air passage through which oxygen is passed into the mouth of the person being treated, the apparatus also including tubular members extending transversely through the body and inserted into the nasal pharyngeal tract for aspirating the person, and an aspirating tube extending through the air passage of the body into the oropharyngeal tract.

Other objects will be apparent from the following description of the presently preferred form of the present apparatus, taken in conjunction with the appended drawings.

DETAILED DESCRIPTION OF INVENTION

The combined resuscitating and aspirating apparatus of the present invention includes a cylindrical member 10 having an air passage 12 extending therethrough. Adjacent one terminal of cylindrical member 10, there is provided a universal adapter 14 of conventional type in the cylinder wall for attachment to resuscitating apparatus, shown to advantage in FIG. 8, and generally designated 16.

The opposite terminal of cylindrical member 10 is provided with a wall 18. A flat arcuate air tube 20 is provided with a flange 21 which is secured to wall 18, wall 18 being provided with a slot, to effect communication of the flattened tube with air passage 12 of cylindrical member 10. At a point adjacent end wall 18, there is provided a lip seal 22 which extends outwardly from the outer periphery of cylindrical member 10, which is adapted for engagement against the teeth of the person being treated with the apparatus. The wall of cylindrical member 10 proximate lip seal 22 is formed to provide opposed lip-receiving concave portions 23, as shown to advantage in FIGS. 1 and 8. At a point adjacent universal adapter 14, cylindrical member 10 is provided with a socket or protuberance 24 having an orifice 26 which is in communication with air passage 12 of cylindrical member 10. A flexible oropharyngeal tube 27 is inserted through orifice 26 of socket 24 which tube extends downwardly through cylindrical member 10 and flattened tube 20 down the throat of the person being treated. The opposite terminal of the tube 27 is connected to a standard mechanical aspirator 28.

It is a salient part of the present invention to provide nasal pharyngeal apparatus which includes a pair of like tubes 29 of rigid construction which extend in spaced parallel relationship transversely of cylindrical member 10 at a point intermediate its length. As shown to advantage in FIG. 3, tubes 29 are flush with the peripheral wall of cylindrical member 10 at one side thereof, and extend through the wall and beyond for a substantial distance at the opposite side thereof. There is thereby provided a cylindrical bore 30 in each tube through which a nasal catheter 32 extends, which tube is freely movable within each tube 29. An aspirator 33 of conventional construction is connected to a terminal of tube 29.

Referring to FIG. 3, it will be seen that the outer terminal of each tube 29 is reduced at 34 to facilitate frictional engagement with a nostril plug 36.

Nostril plug 36 is preferably made of a flexible material such as rubber and includes a body portion 38 of generally conical contour for engagement with nostrils of varying size and shape. One terminal of body 38 is extended at 40 for frictional engagement with reduced portion 34 of tube 29. Plug 36 is provided with a longitudinal bore 42 through which tube 32 extends.

It will be further noted that plugs 36 are spaced apart, thereby permitting insertion thereof in the nostrils, the space between the plugs accommodating the septum of the nose. When properly inserted, an airtight seal is effected.

In FIG. 8, there is illustrated the application of the device of the present invention to a human being wherein a conventional resuscitating supply source 44 is provided with a demand valve 46, both of conventional construction, the demand valve being in turn detachably engaged with universal adapter 14. Alternatively, resuscitation may be effected by a mouth-to-mount method.

In use of the present device, the device is inserted into the mouth with the arcuate flattened tube 20 extending down the throat and lip seal 22 fitted in between the lips and the teeth. Nostril plugs 36 may then be inserted in place, thereby permitting insertion of tubes 29 into the nasal-pharyngeal tract, leading to the digestive tract.

For aspiration of the oropharyngeal tract, tube 27 is inserted through orifice 26, cylindrical member 10 and flattened tube 20 down the throat.

The apparatus of the present invention is then capable of performing a resuscitating function by operation of apparatus 16. Additionally, an aspirating operation may be carried out either simultaneously or selective, aspiration of the nasal pharyngeal tract being effected by operation of aspirator 33 and aspiration of the oropharyngeal tract being accomplished by actuation of aspirator 28. The aspirating procedures do not interfere with the resuscitating procedure or with each other.

With The apparatus of the present invention, simple and economic means, requiring a minimum of inexpensive parts, are employed. By providing means for carrying out resuscitation and aspiration simultaneously, improved medical aid can be given without switching from one type of apparatus for resuscitation and another for aspiration.

While there has been herein shown and described the presently preferred form of the present invention, it is to be understood that such has been done for purposes of illustration only, and that various changes may be made within the scope of the claims hereto appended.
