Abstract

The present invention involves a patient support system. The support system has a fluid bladder and a container. The container has an air pump, a manifold and a CPR dump system. The CPR dump system has a manifold aperture, a plug positioned in the manifold's aperture, a rod interconnected to the plug and protruding from the container's opening, a magnetized alignment apparatus, and a magnetized stop mechanism. The magnetized stop mechanism fastens to the rod and magnetically attaches to the magnetized alignment apparatus which insures the plug is lodged in the manifold's aperture. When a user wants to expeditiously deflate the inflatable fluid bladder, the user pulls on the distal end with sufficient force to detach the magnetized stop mechanism from the magnetized alignment apparatus thereby the plug dislodges from the manifold aperture and allows the inflatable fluid bladder to deflate within a predetermined time frame.

Claims (33)

1. A patient support system comprising:

an inflatable fluid bladder positioned within a patient support unit;

an air pump unit that directs air toward the fluid bladder,

a container having

(A) a manifold (i) positioned between the air pump unit and the fluid bladder, and (ii) having valves that control the amount of air that enters a conduit that directs the air into the fluid bladder; and

(B) a CPR dump system having (i) an aperture in the manifold, (ii) a plug designed to be positioned in the manifold's aperture, (iii) a rod having a proximal end interconnected to the plug and a distal end protruding from an opening in the container, (iv) a magnetized alignment apparatus positioned between the manifold and the container's opening while supporting a portion of the rod, and (v) a magnetized stop mechanism (a) fastened to the rod between the magnetized alignment apparatus and the container's opening and (b) magnetically attached to the magnetized alignment apparatus which insures the plug is lodged in the manifold's aperture;

wherein when a user wants to expeditiously deflate the inflatable fluid bladder, the user pulls on the rod's distal end with sufficient force to detach the magnetized stop mechanism from the magnetized alignment apparatus which causes the plug to dislodge from the manifold aperture and allows the inflatable fluid bladder to deflate within a predetermined time frame.

2. The patient support system of claim 1 wherein the container is positioned within the patient support system.

3. The patient support system of claim 1 wherein the container is positioned exterior to the patient support system.

4. The patient support system of claim 1 wherein a sensor is positioned to determine if the plug is dislodged from the manifold's aperture.

5. The patient support system of claim 4 wherein the sensor transmits a signal to the air pump unit to shut down the air pump unit when the plug is dislodged from the manifold's aperture so the inflatable fluid bladder can deflate within a predetermined time frame.

6. The patient support system of claim 4 wherein the sensor transmits a signal to the manifold to open the valves when the plug is dislodged from the manifold's aperture so the inflatable fluid bladder can deflate within a predetermined time frame.

7. The patient support system of claim 4 wherein the sensor transmits a signal to the air pump unit to reverse the air pump unit's air flow when the plug is dislodged from the manifold's aperture so the inflatable fluid bladder can deflate within a predetermined time frame.

8. The patient support system of claim 4 wherein the sensor is selected from the group consisting of a microswitch, a Hall effect, a magnetic proximity switch, and a giant magneto-restrictive device.

9. The patient support system of claim 1 further comprising a processor interconnected to the manifold to control the valve opening.

10. The patient support system of claim 1 further comprising a processor interconnected to the air pump unit to control when the air pump unit operates.

11. The patient support system of claim 1 wherein the magnetized alignment apparatus has a hole that receives the rod.

12. The patient support system of claim 1 wherein the rod is not magnetized.

13. The patient support system of claim 1 wherein the rod's proximal end is directly connected to the plug.

14. The patient support system of claim 1 wherein the plug connects to a manifold plate and the rod's proximal end connects to the manifold plate.

15. The patient support system of claim 14 wherein the manifold plate is interconnected to a second plug and the second plug is lodged in a second aperture of the manifold when the magnetized stop mechanism is magnetically attached to the magnetized alignment apparatus.

16. The patient support system of claim 1 further comprising a handle at the rod's distal end.

17. The patient support system of claim 1 further comprising a strap positioned between the handle and the container's aperture.

18. The patient support system of claim 1 wherein the magnetized stop mechanism and the magnetized alignment apparatus are partially magnetized.

19. The patient support system of claim 1 wherein the patient support unit is a mattress.

20. A method to perform CPR comprising:

finding a patient in need of CPR positioned on a patient support unit having

a fluid bladder positioned within the patient support unit;

an air pump unit that directs air toward the fluid bladder,

a container having

(A) a manifold (i) positioned between the air pump unit and the fluid bladder, and (ii) having valves that control the amount of air that enters a conduit that directs the air into the fluid bladder; and

(B) a CPR dump system having (i) an aperture in the manifold, (ii) a plug designed to be positioned in the manifold's aperture, (iii) a rod having a proximal end interconnected to the plug and a distal end protruding from an opening in the container, (iv) a magnetized alignment apparatus positioned between the manifold and the container's opening while supporting a portion of the rod, and (v) a magnetized stop mechanism (a) fastened to the rod between the magnetized alignment apparatus and the container's opening and (b) magnetically attached to the magnetized alignment apparatus which insures the plug is lodged in the manifold's aperture;

pulling the rod's distal end with sufficient force to detach the magnetized stop mechanism from the magnetized alignment apparatus so the plug dislodges from the manifold aperture and allows the inflatable fluid bladder to deflate within a predetermined time frame.
