Abstract

The devices and methods described below provide for a lightweight electro-mechanical chest compression device. A fully assembled chest compression device is hand-portable over long distances.

Claims

1. An electro-mechanical chest compression device comprising:

a housing;

a motor disposed in the housing;

a power source operably connected to the housing and to the motor;

a drive spool rotatably attached to the motor, wherein the motor is capable of rotating the drive spool;

a belt attached to the drive spool, said belt capable of extending at least partially around the chest of a patient, wherein rotation of the drive spool tightens the belt to compress the chest of the patient;

wherein the total weight of the housing, motor, drive spool, power source and belt is less than about 30 pounds.

2. The device of claim 1 further comprising a brake operably attached to the motor and wherein the total weight of all components of the device is less than about 30 pounds.

3. The device of claim 1 further comprising a clutch operably attached to the motor and wherein the total weight of all components of the device is less than about 30 pounds.

4. The device of claim 1 further comprising a gearbox, said gearbox containing a gear system operably connected to the motor and to the drive spool, wherein the gear system has a gear ratio of less than 1, and wherein the total weight of all components of the device is less than about 30 pounds.

5. The device of claim 1 further comprising a control system disposed in the housing and operably connected to the motor, said control system capable of controlling the operation of the motor, and wherein the total weight of all components of the device is less than about 30 pounds.

6. The device of claim 5 wherein the control system comprises a processor.

7. The device of claim 6 wherein the control system further comprises a motor controller.

8. The device of claim 7 wherein the control system further comprises a power controller.

9. The device of claim 1 wherein the housing is sized and dimensioned so that a patient may be disposed on the housing and so that the patient may be transported while disposed on the housing.
