Abstract

A mechanical chest compression device is secured to a gurney, transport stretcher or ambulance cot while engaging a patient's thorax to provide mechanical CPR during transport. The mechanical chest compression device compresses the patient's thorax against the gurney deck. The mechanical chest compression device may engage the side rails on the gurney, the gurney deck or any suitable structural elements of the gurney.

First claim

I claim:

1. An apparatus for transporting and treating a patient comprising:
a gurney having a rigid gurney deck;
a motor;
a drive spool operatively connected to the motor;
a belt operatively connected to the drive spool, the belt comprising an upper belt section and a lower belt section, wherein
the lower belt section comprises respective fasteners at each end of two fastener ends of the lower belt section, the fasteners being accessible through respective openings in an upper surface of the rigid gurney deck, and
the upper belt section comprises two complementary fastener ends, each complementary fastener end having a respective complementary fastener for releasably engaging the fasteners of the lower belt section; and

wherein the motor, drive spool and a portion of the belt are within the rigid gurney deck and the motor is operable to drive the drive spool to repetitively contract the belt to cyclically compress and decompress the patient's thorax between the belt and the rigid gurney deck.

2. The apparatus of claim 1 further comprising:
a controller within the rigid patient support platform, the controller operably connected to the motor to control operation of the motor.

3. The apparatus of claim 2 further comprising:
a pad adapted to be disposed between the patient and the rigid gurney deck.

4. The apparatus of claim 2 further comprising:
one or more force sensors adapted to be disposed between the patient and the rigid gurney deck for measuring the force of mechanical chest compressions.

5. The apparatus of claim 2 wherein the one or more force sensors generate data corresponding to the force measured by each of the one or more force sensors and wherein the data is used to control the motor.

6. The apparatus of claim 1 , wherein the upper belt section includes a pull strap and a load distribution section.

7. The apparatus of claim 1 further comprising:
a bladder secured between the patient's chest and the belt.

8. A method for transporting and treating a patient comprising the steps:
providing a gurney having a rigid gurney deck;
providing a motor;
providing a drive spool operatively connected to the motor;
providing a belt operatively connected to the drive spool, the belt comprising an upper belt section and a lower belt section, wherein
the lower belt section comprises respective fasteners at each end of two fastener ends of the lower belt section, the fasteners being accessible through respective openings in an upper surface of the rigid gurney deck, and

the upper belt section comprises
two complementary fastener ends, each complementary fastener end having a respective complementary fastener for releasably engaging the fasteners of the lower belt section, and
two attachment ends, each respective attachment end opposite a corresponding complementary fastener end, wherein the motor, drive spool and a portion of the lower belt section are within the gurney deck;

placing the patient supine on the gurney deck;
securing the attachment ends of the upper belt section of the belt to each other in a superior position relative to the patient's thorax; and
activating the motor to drive the drive spool to repetitively contract the belt to cyclically compress and decompress the patient's thorax between the belt and the gurney deck.

9. The method of claim 8 further comprising the step:
measuring the force of mechanical chest compressions using one or more force sensors adapted to be disposed between the patient and the rigid gurney deck.

10. The method of claim 9 wherein the one or more force sensors generate data corresponding to the force measured by each of the one or more force sensors and wherein the method further comprises the step:
providing the force data to a controller to control the motor.

11. An apparatus for transporting and treating a patient comprising:
a gurney having a rigid gurney deck;
a motor;
a drive spool operatively connected to the motor;
a first spindle and a second spindle laterally spaced from each other and operatively secured within the rigid gurney deck;
a belt operatively connected to the drive spool, the belt comprising an upper belt section and a lower belt section, wherein
the lower belt section comprises respective fasteners at each end of two fastener ends of the lower belt section, each end extending from the drive spool and around one of the first or second spindle and then though an opening in the rigid gurney deck, and
the upper belt section comprises two complementary fastener ends each operable to engage a respective fastener end of the lower belt section; and

wherein the motor, drive spool and a portion of the lower belt section of the belt are within the gurney deck and the motor is operable to drive the drive spool to repetitively contract the belt to cyclically compress and decompress the patient's thorax between the belt and the rigid gurney deck.

12. The apparatus of claim 1 further comprising:
a controller within the rigid gurney deck, the controller operably connected to the motor to control operation of the motor.

13. The apparatus of claim 2 further comprising:
a pad adapted to be disposed between the patient and the rigid gurney deck.

14. The apparatus of claim 2 further comprising:
one or more force sensors adapted to be disposed between the patient and the rigid gurney deck for measuring the force of mechanical chest compressions.

15. The apparatus of claim 2 wherein the one or more force sensors generate data corresponding to the force measured by each of the one or more force sensors and wherein the data is used to control the motor.

16. The apparatus of claim 1 , wherein the upper belt section includes a pull strap and a load distribution section.

17. The apparatus of claim 1 further comprising:
a bladder secured between the patient's chest and the belt.

18. The apparatus of claim 11 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 apparatus.

19. The apparatus of claim 1 , wherein the upper belt section comprises two attachment ends, each respective attachment end opposite a corresponding complementary fastener end, the two attachment ends operable to engage each other in a superior position relative to the patient's thorax.

20. The apparatus of claim 11 , wherein the upper belt section comprises two attachment ends, each respective attachment end opposite a corresponding complementary fastener end, the two attachment ends operable to engage each other in a superior position relative to the patient's thorax.
