Description
1090ZZq~
This invention relates to a small inflatable "pillow"
provided with a pressure gauge for enabling a rescuer ~o accurately control the force applied to the victim's chest when administering external cardiac resuscitation.
When the heart is stopped as a result of injury, poisoning, electric shock, heart attack or other causes, circulation sufficient to maintain life may be maintained by therhythmic application of the correct amount of pressure to the chest.
This technique is known as manual, external, cardiac compression, and when combined with artificial respiration it is called cardiopulmonary resuscitation (CPR).
In adult males, for example, the correct pressure or Eoroe is approximately ninety pounds. If too little pressure is applied the circulation created, if any, will not be sufficient to prevent brain damage or even death. On the other hand, if the pressure applîed is too great, broken ribs, punctured lungs and other damage may result. Further, application of pressure on too small an area of the chest can more readily result in broken ribs and other damage, for example, if the knuckles of the rescuer's hand are pressing on the victim's ribs. Also, if the pressure is not applied evenly but applied in quick jabs, the likelihood of injury is increased, and if the pressure is not applied rhythmically and with proper timing, satisfactory results may not be obtained.
Therefore, it is an object of this invention to provide a method and apparatus whereby the pressure applied during external cardiac resuscitation may be observed by the person administering such aid.
",,~, ~09~Z26 It is a further object of this invention to provide an inexpensive and compact device which will indicate the amount of pressure or force applied during external cardiac resuscitation.
- la -It is also an obj ect of this invention to provide an inexpensive and compact pressure distribution device which optionally may not have the pressure measuring and indicating means.
It is another object of this invention to provide one or more of the above described devices with a timing indication means to insure that the rescuer will use the appropriate rhythm in the application of external cardiac resuscitation.
It is a further object of the invention to provide the above-mentioned devices with an adhesive backing so that the device need only be located in the proper position on the victim one time.
Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of the invention. The objects and advantages are realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
To achieve these and other objects the present invention provides for an inflatable structure of heavy vinyl or other suitable material approximately three inches square and two inches high ~when inflated) having a pressure indicating device such as a pressure gauge associated there-with. The structure is inflated by mouth through a suitable inflation valve such as are found on air mattresses. The gauge may be calibrated to indicate the Pressure or force a~lied to a victim by placing the inflatable structure on a spring weight scale and applying various pressures (especially ~oaoz26 in the ran~e required for external ca~diac resuscitation~ on the structure and recording these pressures from the spring weight scale onto the face of the pressure gauge indicator face. In experiments it has been found that a pressure of eight pounds per square inch on the gauge is representative of a downward force on the inflatable structure of ninety pounds.
In use, the above described external cardiac resuscitation aid is inflated by mouth and placed on a victim's chest over the lower sternum, and pressure or ~orce is applied to theviGtrm'~schest directly thro~lgh the device. The user will o~serve the gauge to cbtain a substantially instanteous reading each ti~e he applies pressure (about once per second~ to he sure that the proper pressure is attained.
In another embodiment a timing device such as an easily readable stop watch may be attached to the device to enable the rescuer to maintain the proper rhythm. Any other suitable adjustable timing device can be used using audible and/or visual signals, as an example. Electronic or other timing means and even a compact metronome device could be used. For example, with two rescuers the rhythm should be one compression and relaxation per second (compression comprising one half second relaxation one half second).
In another embodiment, the timing means may be an integral part of the pressure gauge, for example, the pressure gauge may be designed so that an appropriate time interval, e.g. one half second, is required for the pressure indicator pointer to relax to zero. Ideally, this timing feature is adjustable to suit diferent circumstances.
The resiliency of the inflatable "pillow" or other pressure applying means is a valuable feature of the invention.
This resiliency tends to reduce the chances of damage or injury to the patient when administering cardiopulmonary resuscitation (CPR) by virtue of the fact that it provides ~O~OZZ6 for an even distribution of pressure. Further, it tends to absorb the harmful effects of improperly applied (CPR), such as sharp jabs rather than even, regular compressions.
The "pillow" acts as a resilient force equalizing and transmit-ting member and as a force receiving and transmitting means by evenly aistributing the force applied directly thereto by the rescuer and by transmitting that force to the patient's ches~.
Accordingly, one embodiment of the invention would consist simply in an inflatable "pillow" or other similarly shaped structure of suitable material such as foam rubber for the application of CPR. Such a device would be of value even though it did not have the pressure sensing and pressure indicating means and other features described above. However, it could include these additional features or any combination thereof, including the use of the timing means.
Further improvement to the above-described embodiments is the provision of a pressure sensitive adhesive surface, such as medical adhesive tape, on the bottom of the "pillow"
or resilient cushion. This adhesive would have a peel-off cover. Thus, the rescuer need only locate the proper position for the device, peel off the cover and apply it to the victim's chest. Then, should the rescuer have to stop the CPR for an interval because of moving or transporting the victim or to apply mouth-to-mouth resuscitation (one man rescue) the rescuer will not lose time in reapplying CPR because the device will have remained in the proper position on the victim's chest. Further, the chance of causing damage by inadvertently applying pressure in the wrong place will be greatly reduced.
~ny type of suitable pressure-sensing device coupled with a suitable pressure indicating means may be employed in the practice of this invention. For example, an electrical lO~OZZ6 transducer might be used to sense pressure in the inflatable "pillow" or might be used to sense the direct pressure applied through the resilient cushion to the victim. Pressure indicating means may be a visual and/or an audible signal.
