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 resuscitation and alert system comprising:

a resuscitation device comprising a chest compression device having a compression belt and a buckle for securing the compression belt around the chest of the victim; and

sensing means for determining when the resuscitation device is in use, said sensing means capable of generating a signal indicating that the resuscitation device is in use and transmitting said signal to other components of the system;

wherein the sensing means comprises a sensor which senses when the buckle has been latched, thereby treating the buckled condition of the compression belt as an indication that the resuscitation device is in use;

computer storage means for storing information corresponding to the location of the resuscitation device;

communicating means for communicating with an emergency medical system;

computer control means for receiving input from the sensing means, and controlling the communicating means to initiate communication with emergency medical system whenever the input from the sensing means indicates that the device is in use, and communicating the information corresponding to the location of the resuscitation device.

2. The system of claim 1, wherein the communicating means comprises a telephone controlled by the computer control means or a separate computer control system, wherein said computer control means or a separate computer control system is programmed to initiate a telephone call to a 911 emergency system and communicates the information corresponding to the location of the resuscitation device to the 911 emergency medical system.

3. The system of claim 1 wherein the communicating means automatically initiates contact with a 911 emergency system when the device is in use.

4. The system of claim 1 further comprising:

at least one rechargeable battery operatively connected to the resuscitation device, said rechargeable battery having charging connections for connection to an electrical power supply for charging the battery when not in use;

second sensing means for sensing the disconnection of the device from the charging connection when the device is disconnected from the electrical power supply and providing an input to the communicating means indicating that the device has been removed from the charging connection; and

wherein the communication means initiates a communication to emergency medical personnel upon receiving input from the second sensing means that the device has been disconnected from the charging connection.
