Abstract

Devices and methods for performing CPR on a patient within an imaging field of an imaging device. The device has a compression belt and a belt tensioning mechanism, both located on or in the device such that the head, neck, thorax and abdomen of the patient may be place within the imaging field with the compression belt installed about the patient and the belt tensioning mechanism will be located outside of the imaging field.

Claims

1. A device for compressing the chest of a patient while imaging the patient in an imaging system, said imaging system defining an imaging area which may encompass a portion of the patient'"'"'s abdomen, thorax, neck or head, said device comprising:

a platform adapted to be disposed beneath the patient'"'"'s thorax while the patient is disposed within a gantry of the imaging system;

a belt operably connected to the platform and adapted to extend at least partially around the chest of the patient;

the belt comprising a load distributing portion adapted to extend across the patient'"'"'s chest, and tensioning portions extending from the load distributing portion, and posteriorly relative to the patient;

a tensioning means, disposed relative to the load distributing portion of the belt such that it is located outside of the imaging area when the patient is disposed on the platform with the belt extending around chest of the patient; and

translating means for translating motion of the tensioning means into anterior/posterior tension in the tensioning portion;

wherein translating means comprises spindles disposed to guide the tensioning portions on either side of the patient'"'"'s body from an anterior/posterior direction to a lateral/medial direction to a superior/inferior direction, and the tensioning means comprises a linear actuator connected to the tensioning portions and aligned along the superior/inferior direction in order to pull the tensioning portions superiorly or inferiorly relative to the patient.

2. The device of claim 1 wherein the tensioning means comprises a pneumatic piston with an actuator rod secured to the tensioning portions of the belt.

3. The device of claim 1 wherein the tensioning means comprises a rotary-to-linear converter secured to the tensioning portions of the belt.

4. The device of claim 1 wherein the tensioning means comprises a rotary actuator aligned to pull the tensioning portions of the belt along the superior/inferior direction.

5. The device of claim 1 wherein the tensioning means comprises a motor with a drive shaft oriented transversely to the superior/inferior direction.

6. A device for compressing the chest of a patient while imaging the patient in an imaging system, said imaging system defining an imaging area which may encompass a portion of the patient'"'"'s abdomen, thorax, neck or head, said device comprising:

a platform adapted to be disposed beneath the patient'"'"'s thorax while the patient is disposed within a gantry of an imaging system;

a belt operably connected to the platform and adapted to extend at least partially around the chest of the patient;

the belt comprising a load distributing portion adapted to extend across the patient'"'"'s chest, and tensioning portions extending from the load distributing portion, and posteriorly relative to the patient;

a tensioning means connected to the tensioning portions and aligned along a superior/inferior direction in order to pull the tensioning portions superiorly or inferiorly relative to the patient; and

translating means for translating motion of the tensioning means into anterior/posterior tension in the tensioning portions.

7. The device of claim 6 wherein the tensioning means comprises a pneumatic piston with an actuator rod secured to the tensioning portions of the belt.

8. The device of claim 6 wherein the tensioning means comprises a linear actuator secured to the tensioning portions of the belt.

9. The device of claim 6 wherein the tensioning means comprises a rotary-to-linear converter secured to the tensioning portions of the belt.

10. The device of claim 6 wherein the tensioning means comprises a rotary actuator aligned to pull the tensioning portions of the belt along the superior/inferior direction.

11. The device of claim 6 wherein the tensioning means comprises a linear actuator aligned pull the tensioning portions superiorly or inferiorly relative to the patient.

12. The device of claim 6 wherein the tensioning means comprises a motor with a drive shaft oriented transversely to the superior/inferior direction.

13. The device of claim 6 wherein the translating means comprises spindles disposed to guide the tensioning portions on either side of the patient'"'"'s body from an anterior/posterior direction to a lateral/medial direction to a superior/inferior direction, and the tensioning means comprises a linear actuator connected to the tensioning portions and aligned along the superior/inferior direction in order to pull the tensioning portions superiorly or inferiorly relative to the patient.

14. The device of claim 6 wherein translating means comprises spindles disposed to guide the tensioning portions on either side of the patient'"'"'s body from an anterior/posterior direction to a lateral/medial direction to a superior/inferior direction, and the tensioning means comprises a motor operably connected to a drive spool oriented transversely to the superior/inferior direction, said drive shaft operable connected to the tensioning portions in order to spool the tensioning portions upon the drive spool and thereby the tensioning portions superiorly or inferiorly relative to the patient.
