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 . fig1 - 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 fig1 - 5 . body 14 &# 39 ; s back surface 20 has desk side support notch 22 embedded at approximately a 45 degree angle as shown in fig2 - 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 fig1 . 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 fig6 and is of sufficient length to allow even a small caregiver to reach around a very large adult . fig7 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 . 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 fig8 . fig9 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 . fig1 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 .
this invention relates generally to a device to assist a smaller person in applying the heimlich maneuver to a larger person that is sitting , standing or lying prone on his back or in performing the maneuver on himself .
