Abstract

A resuscitation device for automatic compression of a victim'"'"'s chest using a compression belt operably attached to a platform upon which a patient rests. In use, the compression belt is wrapped around the patient and at least one spindle operably attached to the platform.

Claims

1. A device for compressing the chest of a patient, said device comprising:

a platform upon which a patient can rest;

a belt operably connected to the platform and adapted to extend at least partially, around the chest of the patient, said belt further adapted for anterior-posterior compression of the patient;

a motor operatively connected to the belt, wherein the motor is capable of driving the belt with sufficient force such that the belt can compresses the chest of the patient with an anteriorposterior compression;

a drive spool operatively attached to the motor and to the belt;

a spindle operably connected to the platform;

wherein the belt is disposed around the patient and then around the spindle disposing the spindle between the belt and the patient; and

a bladder disposed between the belt and the patient'"'"'s sternum, said bladder being filled with a pressure transmitting medium.

2. A device for compressing the chest of a patient, said device comprising:

a platform upon which a patient can rest;

a belt operably connected to the platform and adapted to extend at least partially around the chest of the patient, said belt further adapted for anterior-posterior compression of the patient;

a motor operatively connected to the belt, wherein the motor is capable of driving the belt with sufficient force such that the belt can compresses the chest of the patient;

a drive spool operatively connected to the motor and the belt;

a first spindle operably connected to the platform and disposed to the right of the patient, a second spindle operably connected to the platform and disposed to the left of the patient, and a third spindle operatively connected to the platform and disposed beneath the patient;

wherein the belt is disposed around the first spindle, around the patient, around the second spindle, and around the third spindle; and

a bladder disposed between the belt and the patient said bladder being filled with a pressure transmitting medium.

3. The device of claim 2 wherein the distance between the first spindle and the second spindle is in the range of about 12 inches to about 20 inches.

4. The device of claim 2 wherein the first spindle and the second spindle are disposed such that the device, when used on the patient, will perform anterior-posterior compressions on the patient.

5. The device of claim 2 wherein the first spindle and the second spindle are disposed posterior of the spine of the patient when the patient is placed on the device.

6. The device of claim 2 wherein the first spindle and the second spindle are disposed laterally of the spine and are disposed posterior of the scapula of the patient when the patient is placed on the device.

7. The device of claim 2 wherein the first spindle is disposed about in the area of the left axilla of the patient and the second spindle is disposed about in the area of the right axilla of the patient when the patient is placed on the device.
