Abstract

A positioning device for use in apparatus for treating sudden cardiac arrest in a patient in supine position by providing chest compressions at the lower end of the sternum prevents the apparatus from moving in a caudal direction. The apparatus includes a frame enclosing the patient at a sternal transversal plane and a pneumatic compression/decompression unit mounted on the frame. The device includes a flexible strap having a first end, a second end and a tensioning component disposed between the first and second ends. First and second end portions of the strap include a mechanism for attachment to the apparatus. The flexible strap has a mounted tensioned length sufficient to extend around the patient'"'"'s neck. At least one of the end portions is releasably attached.

Claims

1. A combination of an apparatus for treating sudden cardiac arrest in a patient in a supine position by providing chest compressions at the lower end of the sternum with a positioning device which prevents the apparatus from moving in a caudal direction, the combination comprising:

the apparatus including

a frame enclosing the patient at a sternal transversal plane; and

a pneumatic compression/decompression unit mounted on the frame; and

the positioning device including

a flexible strap having a first end, a second end and a tensioning component disposed between the first and second ends, the flexible strap further including first and second end portions extending from the first and second ends, respectively, the first and second end portions each including an attachment mechanism configured for attachment of the first and second end portions to the apparatus at first and second positions thereof, respectively, at least one of the end portions being releasably secured to the attachment mechanism, the flexible strap also having a mounted tensioned length sized to extend around the patient'"'"'s neck.

2. The combination of claim 1, wherein the tensioning component is integrated with the attachment mechanism.

3. The combination of claim 1, wherein the positions of attachment are in an anterior frontal plane.

4. The combination of claim 1, wherein the flexible strap is selected from the group consisting of a strap, belt, ribbon, band and wire.

5. The combination of claim 4, where the flexible strap means is of a polymer material or a mixture of polymer materials.

6. The combination of claim 1, wherein the attachment mechanism comprises a snap connection.

7. The combination of claim 6, wherein the snap connection comprises two members, one member of the snap connection being mounted on the frame and the other member being mounted on one of the end portions of the flexible strap.

8. The combination of claim 7, wherein the frame comprises two legs disposed on either side of the patient, the one member of the snap connection being mounted on one of the legs.

9. The combination of claim 7, wherein the mounting of the one member of the snap connection on the frame is releaseable.

10. The combination of claim 8, wherein the mounting of the one member of the snap connection on the frame is configured to allow the one member to be displaced between a proximal and a distal face of the frame.

11. The combination of claim 1, wherein the positioning device further comprises a neck support.

12. The combination of claim 11, wherein the neck support is of a compressible material.

13. The combination of claim 11, wherein the neck support is slidably displaceable along the flexible strap.

14. The combination of claim 13, comprising wherein the positioning device further comprises a hindering mechanism operable to hinder displacement of the neck support in a loaded state thereof.

15. The combination of claim 7, wherein the tensioning component includes the member of the snap connection mounted on the end portion of the flexible strap.
