Abstract

A resuscitation device for automatic compression of victim'"'"'s chest using a compression belt which exerts force evenly over the entire thoracic cavity. The belt is constricted and relaxed through a motorized spool assembly which repeatedly tightens the belt and relaxes the belt to provide repeated and rapid chest compression. An assembly includes various resuscitation devices including chest compression devices, defibrillation devices, and airway management devices, along with communications devices and senses with initiate communications with emergency medical personnel automatically upon use of the device.

Claims

1. A modular chest compression system for performing CPR on a patient having a chest comprising:

a support board sized and dimension to extend from at least a lower lumbar region to a shoulder region of the patient;

a compression module having an attachment means releasably and operably attached to the support board, said compression module comprising a spool assembly and a compression belt operably coupled to the spool assembly, said belt sized and dimensioned to extend around the chest of the patient; and

an electric motor disposed within the support board wherein the motor is operably connected to the spool assembly when the compression module is coupled to the support board;

wherein the spool assembly comprises a drive spool operably connected to the compression belt, and the drive spool comprises a slot sized and dimensioned to receive the belt.

2. A modular chest compression system for performing CPR on a patient having a chest comprising:

a support board sized and dimension to extend from at least a lower lumbar region to a shoulder region of the patient;

a compression module having an attachment means releasably and operably attached to the support board, said compression module comprising a spool assembly and a compression belt operably coupled to the spool assembly, said belt sized and dimensioned to extend around the chest of the patient;

an electric motor disposed within the chest compression module, said electric motor operably connected to the spool assembly;

wherein the spool assembly comprises a drive spool operably connected to the compression belt and the drive spool comprises a slot sized and dimensioned to receive the belt.

3. A compression module for use with an automatic chest compression system for performing CPR comprising:

a housing for enclosing the compression module;

an attachment means coupled to the housing, said attachment means adapted for releasable and operable attachment to a support board in the automatic chest compression system;

a spool assembly disposed within the housing, the spool assembly including a drive spindle with a slot sized and dimensioned to receive the belt;

a compression belt sized and dimensioned to extend around a chest of a patient operably attached to the spool assembly;

wherein the belt is able to compress the chest of the patient when the housing is operably attached to the automatic chest compression system and the belt is disposed around a patient.
