PORTABLE HEIMLICH MANOEUVRE DEVICE
A device for use in performing the Heimlich manoeuvre comprises a domed element forwardly supported from a handle extending on diametric sides thereof. Preferably the domed element extends rearwardly of the handle.
The device permits the manoeuvre to be performed by one person on another, or for it to be self-applied.
Description
:
This invention relates to a portable device for safely providing emergency compressive force to the abdomen of a choking person in the performance of the Heimlich manoeuvre.
The Heimlich manoeuvre calls for the rapid, although not violent, application of a force to the abdomen, to cause the rapid expulsion of air from the stomach and lungs through the mouth, and the . e~ection therewith of food causing a blockage in the throat. The manoeuvre is commonly performed by one person, the "aider", on ~3 another, the "victim", with the arms of the aider being encircled . 10 about the torso of the victim, the aider's hands being grasped together at the victim's abdomen.
When properly performed, the Heimlich manoeuvre employs a particular positioning of the hands which may be achieved by placing one's hands together so the fingers point in opposite directions and generally overlap along the length. The hands are then closed into -~ fists by closing the fingers toward each of the respectlve palms so that the fingers of each hand are between the fingers and palm of the other. This positioning produces a generally spherical or ovoid shape ,~ which may be described as a pair of interlocking, closed fists. The ~ 20 use of this positioning of the hands is considered by those ; knowledgeable in the field to be advantageous in the efficient ., ,'!,~ employment of the Heimlich manoeuvre.
As a result, any person having a choking related obstruction of the airway, if unable to get assistance or to simply cough the , 25 blockage out from the airway, would pass out and die in short order.

t ., ,~ .
.; , . . I
202s234 A further limitation of the Heimlich manoeuvre is that the arms of the person giving aid to the victim must pass around the torso of the victim and clasp in the manner noted above in order to deliver a short upward blow to the abdomen in the approximate area of the diaphragm. If the person giving aid is not large enough to extend his . or her arms around the choking victim's torso, the technique cannot be properly applied. Furthermore, to the extent that the party aiding the victim must stretch his or her arms to achieve the appropriate positioning of the hands, the technique would be less effective. Thus it is quite common for a relatively smaller person to be unable to aid a relatively larger person. Conversely, when a significantly larger but inexperienced person seeks to aid a relatively smaller victlm, crushing or impact in;uries to the lower rib cage are not uncommon.
These injuries are generally caused by the compression of the lower ribs by the aider's forearms in the process of applying the upward and inward force required to dislodge the object. This impingement of the forearms on the rib cage of the victim also serves to diminish the effectiveness of the aider's attempts to dislodge the obstruction.
It has not heretofore been possible for the force required to be delivered by an experienced person with the hands in the appropriate position to be delivered by an untrained or inexperienced ' samaritan with minimal time to prepare for and execute the required ; assistance.

It is still another object of the invention to provide a ~, device that may assist the administration of the Heimlich manoeuvre by persons having little or no knowledge thereof.
:.
In accordance with a broad aspect of the invention, a device for use in the performance of the Heimlich manoeuvre comprises a :
central portion, having front and rear ends and an axis extending ' between said ends, and handle means extending generally laterally ;.iJ therefrom on diametrically opposed sides. The central portion ~i 15 includes a domed element, the peak of which is located at the front .~ end of the central portion. The domed element has a base having a ~erimetric measurement approximately equal to the circumferential measurement across the irregular surface of the knuckles of a pair of interlocked, closed fists when grasping each other as they would be when performing the Heimlich manoeuvre. The handle means of the device are operably connected to the domed element and are sufficiently rigid that force applied thereto would be operably transferred to the domed element.
These foregoing ob~ects and aspects of the invention, together with other objects, aspects and advantages thereof, will be :

'' ~ ', ~ ' ' , "' ' ' more apparent from the following description of a preferred embodiment thereof, taken in conjunction with the following drawings.
. Figure 1 is an elevational view showing the front end of the '~ device;
Figure 2 is a partial sectional view taken along lines 2-2 of Figure 1, seen in the direction of the arrows; and ,i Figure 3 is a sectional view taken along lines 2-2 of Figure `~1, showing an alternative embodiment of handle means 22.
Referring to the drawings in detail, preferred embodiment of a device constructed in accordance with the present invention is identified generally by the numeral 10. Device 10 comprises a central portion 8 having a front end 16 and a rear end 18. Central portion 8 comprises a domed element 30 and a right circular cylinder 12 defined by a cylindrical wall 14. Device 10 further comprises a generally rigid handle 22 extending laterally from central portion 8 on diametrically opposed sides thereof intermediate ends 16 and 18.
The lateral ends 24 of handle 22 are bulbously profiled. Handle 22 is provided along each transverse side thereof with a pair of ',crescent-shaped indentations 26 to reduce the width of the handle in intermedlate portions thereof.
;`The materials of construction of device 10 are not critical.
Preferably in the embodiment shown, domed element 30 is somewhat ~,resilient whereby it will yield inwardly under the application of too -,;great a force thereto, the yieldability also being somewhat controlled by the pressure within chamber 34. Otherwise, the materials of construction of device 10 will preferably be relatively unyielding.

It will be appreciated that the domed element 30 of the device is intended to be located in the pit of the stomach, or at the solar plexus, and it will accordingly have a diameter or cross-sectional dimension of approximately 3 inches (7.5 cm) to 10 inches (25 cm), being approximately the diametric measurement from the outside of the most protruding knuckle on one hand to the outside of $ the most protruding knuckle on the other hand of a pair of interlocking closed fists, as described above, of a male adult of average stature. Domed element 16 will normally project about 2 to 4 inches (5 to 10 cm) above handle 22.
Suitably, wall means generally indicated by the numeral 32, may also be provided to form a rear end closure at some point to the rear of front end 16. In one form of the device, a concave rear end closure 42 is employed, to assist in locating the device on an external corner of a heavy item of furniture for example, when it is desired to self-administer the Heimlich manoeuvre. Alternatively, a , convex rear end closure 44 may be employed in order to provide the device with three fold symmetry whereby its immediate application may be most apparent. In such a case convex rear end closure 44 should be resiliently yieldable to facilitate its seating upon the object being pressed against. Where the device is intended for use primarily by persons having no knowledge of the manoeuvre, indicia 40 are , desirably located on the front end of the cylindrical element to , indicate that it should be located over the abdomen of the victim.
In use for performing the Heimlich manoeuvre, the device 10 ' is placed with the domed element 16 located on the abdomen of the .~

victim. Typically when the device 10 is being manipulated by another person, the other person will stand to the rear of the victim and grasp the gripping means 24 located at the distal ends of the handle means 22, and exert a strong force to compress the abdomen. However, it will be appreciated that the device 10 may be used by the victim without benefit of any assistance. This may be carried out by abutting the rear end 18 of the central portion against an unyielding surface, for example the floor or a wall or heavy furniture, where upon the victim may force the abdomen onto the front end of the j cylindrical element.
, In this position, domed element 30 of the device will normally be centred approximately between the lowest extremity of the ninth ribs. As the device is pulled into the abdomen the upper indentations 26 on the handle means 22 will tend to provide a relief for the cartilages of the lower ribs to prevent an excessive force ~, being applied thereto. When the Heimlich manoeuvre is being performed by one person on another, the lateral ends 24 of handle 22 are grasped and pulled sharply into the abdomen of the victim, the bulbous ends ; of the handle forming gripping means. It will be appreciated that a ~ 20 number of different gripping means may be used to ensure that the -; first aider has a sufficiently tight grip on the device.
The rigidity of handle 22 tends to concentrate the applied ~..
compressive force where it is most desirable, and also to effectively extend the reach of the aider, thereby permitting a person of relatively small stature and strength to perform the Heimlich ; manoeuvre on a significantly larger person. Desirably, the handle 22 ?~

-will be shaped in such a manner as to reduce the possibility of a force being applied to the rib cage during the performance of the manoeuvre, for example by shaping the handle with appropriately spaced and sized indentations 26 on the transverse edge thereof in order to permit the handle to pass beneath the ribs of the victim rather than :~impinging upon them.
~Preferably a portion of the device should be resiliently , ,, yielding, so as to reduce the poss$bility of too great a force being applied to the victim. Such reduction in force will facilitate a maximal exertion of force by the person performing either the Heimlich manoeuvre, while limiting the chances of injury to the rib cage of the victim. Conveniently such portion may comprise the front end 16 of the device 10 and more specifically the domed element 30. Suitably, ,the front end may be supported by a closed volume of gas contained within the central portion, although other means may also be used as convenient.
`In operation by a choking victim who is otherwise unaided, `~6lt is desirable that the victim be able to exert maximal therapeutic force against a floor or wall without his or her fingers being crushed against that surface. There are two main embodiments of the invention , 1 through which this end may be achieved which are shown in Figure 2 and Figure 3 respectively. In each case lateral ends 24 of handle 22 are , positioned forward of the rear end 18 of central portion 8 thereby ;permitting the fingers of the victim to avoid impingement upon the surface against which the device is being pressed. As shown in Figure . .
~2, one embodiment is cylinder 12 extending rearwardly from handle 22 . .

An alternative embodiment is described in 5 Figure 3, wherein the handle 22 is not planar but is rather curved in f order to ensure that lateral ends 24 will be forwardly spaced from the 3$ surface upon which rear end 18 is being applied, thereby preventing the implngement of the victim's fingers against the surface, against ,f which rear end 18 is abutted when in use.
It will be apparent that many changes may be made to the ' illustrative embodiments, while falling within the scope of the invention and it is intended that all such changes he covered by the if claims appended hereto.
