BACKGROUND 
       [0001]    1. Field of Invention 
         [0002]    This invention relates generally a device to assist a smaller person with applying the Heimlich maneuver to a larger person. 
         [0003]    2. Prior Art 
         [0004]    The Heimlich Maneuver is a well understood procedure for assisting a person that is choking on a piece of food lodged in his throat. It involves getting behind the choking victim, reaching around the victim with both hands, making a fist of one hand and placing it just below the rib cage of the victim, covering it with the second hand and performing a quick upward jerking motion, compressing the diaphragm and forcing air to flow rapidly through the esophagus dislodging the obstruction. 
         [0005]    There are several problems with the standard approach to the Heimlich Maneuver. First if the victim is a much larger person than the care giver she might not be able to reach around him to get her hands in the proper position. In most food choking incidents the victim is sitting in a dining room chair which further complicates the reach around problem. Many other choking incidents occur when the victim is eating alone and there is no one around to institute the life saving technique. 
         [0006]    There have been many attempts to resolve these problems as indicated in the cited patents and advertising literature. There are several that utilize a round ball shape as an approximation of the human fist. Some show use with one hand while others have either straight, rigid handles or flexible handles that serve to extend the caregiver&#39;s reach. Others have an active interface end mounted on some type of shaft that is be placed against some immovable object allowing the solitary victim to fall against the device, dislodging the obstruction. 
         [0007]    None of the prior art devices however take the shape of the human breast plate and rib cage into consideration of the designs of their interface to the body. Many, even though they offer some reach extenders, do not provide sufficient reach for very large victims or small caregivers. The rounded or blunt interfaces do not allow for decreasing resistance to penetration that is achieved with sharper sloped interface surfaces. 
       SUMMARY 
       [0008]    The general object of the present invention is to provide an improved choking assist device. 
         [0009]    The specific objectives of this invention are to provide a very low cost device for the assistance of choking victims by caregivers that:
       1. are either too small or insufficiently trained in the Heimlich maneuver to effectively carry out the manual procedure.   2. can be utilized while choking victim is still seated.   3. can be utilized by a solitary victim on himself.   4. can be utilized while victim is lying on his back.   5. takes into account the shape of the sternum and rib cage for maximum pressure on the diaphragm while minimizing the potential damage to the ribs.

       DESCRIPTION 
       [0027]    In order that the invention may be more fully understood, Adjustable Heimlich Maneuver Device  12  will now be described by way of example with reference to the accompanying drawings. 
         [0028]      FIGS. 1-6  illustrate Adjustable Heimlich Maneuver Device  12 . It is comprised of body  14  and strap  16 . Body  14  has front surface  18  that has a concave shape, narrower at the front and top and wider at the back and bottom as illustrated in  FIGS. 1-5 . Body  14 &#39;s back surface  20  has desk side support notch  22  embedded at approximately a 45 degree angle as shown in  FIGS. 2-5 . It also has hand rest  28  across the bottom of back surface  20  for manually applying force to body  14  when victim is in prone position as in  FIG. 10 . Strap  16  is a flexible strap that is either connected on each side of body  14  or body  14  has a slip fit slot through body  14  on which body  14  slides on strap  16  as shown in  FIG. 6  and is of sufficient length to allow even a small caregiver to reach around a very large adult. 
       Operation: 
       [0029]      FIG. 7  illustrates a standard use of Adjustable Heimlich Maneuver Device  12  as body  14  is shown placed between the navel and sternum and strap  16  is wrapped around the hands of a caregiver and utilized to pull body  14  rapidly upward in a jerking motion to expel a large burst of air by applying force to the stomach, diaphragm and lungs. The shape of body  14 &#39;s front surface  18  is critical to the improved function relative to standard spherical shapes and is designed to fit between the navel and the sternum. The narrowing at the interface front edge allows for the force to be concentrated in a smaller area increasing the local pressure at point of attack. The top to bottom taper allows body  14  to be nestled close to the sternum directly over the diaphragm without putting pressure on the victim&#39;s ribs which suffer the most damage from improperly applied Heimlich Maneuvers. 
         [0030]    The fact that strap  16  is quite long allows a similar application even though the victim remains seated, perhaps even slumped over as shown in  FIG. 8 . 
         [0031]      FIG. 9  shows an application of Adjustable Heimlich Maneuver Device by a solitary victim. In this case the victim places back surface  20  of body  14  at desk side support notch  22  on any square cornered solid piece of furniture, places his abdomen against front surface  18  of body  14  and leans sharply in a rearward and down motion forcing a burst of air, clearing the breathing channel. 
         [0032]      FIG. 10  shows yet another method of use of Adjustable Heimlich Maneuver Device  12  where the victim has already fallen to the floor. In this case the victim is rolled onto his back and body  14  is placed in the same position as before and the heel of the care giver&#39;s hand is placed on hand rest  28  and a sharp downward and forward force is applied again forcing a burst of air through the larynx and clearing the air way.
