Inflatable mattress for a bed
View Patent ↗A support apparatus includes a rotation therapy device, a pulsation therapy device, a dynamic therapy device, and a control system for operating the devices.
1. A support apparatus for supporting a person in a supine position, the apparatus comprising
an inflatable support assembly including a rotational therapy device and a pulsation therapy device,
a supply of pressurized air, and
a control system including a rotation control portion having a first slave processor, a pulsation control portion having a second slave processor, and a master processor in communication with the rotation control portion and in communication with the pulsation control portion, the processor configured (i) to provide commands to the rotation control portion to control the operation of the rotation control portion and (ii) to provide commands to the pulsation control portion to control operation of the pulsation control portion, wherein the master processor provides information and commands to each of the first and second slave processors, and the first and second slave processors control hardware associated with the respective rotation therapy device and pulsation therapy device to deliver therapy to a person supported on the support apparatus.
2. The support apparatus of claim 1 , wherein the pulsation therapy device comprises a pulsation bladder configured to selectively receive pressurized air from the source of pressurized air, the pulsation therapy device positioned to transmit pulsation therapy to the torso of a person supported on the inflatable support assembly.
3. The support apparatus of claim 2 , wherein the control system causes the pulsation control portion to produce air pulses to the pulsation bladder to provide pulsation therapy.
4. The support apparatus of claim 3 , wherein the inflatable support assembly further comprises normally inflated support cushion positioned to support the upper body of a person supported on the inflatable support assembly.
5. The support apparatus of claim 4 , wherein the inflatable support assembly includes a lower foam layer and at least a portion of the normally inflated support cushion is positioned directly above the lower foam layer.
6. The support apparatus of claim 5 , wherein the pulsation therapy device is supported on the normally inflated support cushion.
7. The support apparatus of claim 6 , wherein the inflatable support assembly includes a pair of foam members positioned on opposite sides of the head of a person supported on the inflatable support assembly.
8. The support apparatus of claim 1 , wherein the rotation device comprises a normally inflated bladder configured to support a person on the support apparatus.
9. The support apparatus of claim 8 , wherein the control system causes the rotation control portion to deflate at least a portion of the rotation therapy device to cause a person to be rotated on the support apparatus.
10. The support apparatus of claim 9 , wherein the inflatable support assembly includes a normally inflated cushion and the normally inflated cushion is supported on the rotation therapy device.
11. The support apparatus of claim 10 , wherein the pulsation therapy device comprises a pulsation bladder configured to selectively receive pressurized air from the source of pressurized air, the pulsation therapy device positioned to transmit pulsation therapy to the torso of a person supported on the inflatable support assembly.
12. The support apparatus of claim 11 , wherein the control system causes the pulsation control portion to produce air pulses to the pulsation bladder to provide pulsation therapy.
13. A support apparatus including a head end and a foot end, the support apparatus comprising
a control system including a master processor, a rotation control portion including rotation control logic, a pulsation control portion including rotation control logic, and a dynamic control portion including dynamic control logic,
a rotation therapy device controlled by the rotation control portion of the control system,
a pulsation therapy device controlled by the pulsation control portion of the control system, the pulsation therapy device supported on the rotation therapy device,
a dynamic therapy device controlled by the dynamic control portion of the control system, the dynamic therapy device supported on the rotation therapy device,
a foam base member supporting the rotation therapy device, and
a foam block positioned at the head end of the rotation therapy device.
14. The support apparatus of claim 13 , wherein the rotation therapy device comprises a normally inflated bladder.
15. The support apparatus of claim 14 , wherein the dynamic therapy device comprises a normally inflated bladder.
16. The support apparatus of claim 15 , wherein the pulsation therapy device comprises a pulsation bladder configured to be selectively inflated and the pulsation control portion of the control system is configured to cause air pulses to be transmitted to the pulsation bladder to cause pulsation therapy to be delivered to a person supported on the support apparatus.
17. The support apparatus of claim 16 , wherein the master processor is a node on a network and the rotation control portion, pulsation control portion, and dynamic control portion do not communicate directly with the network.
18. The support apparatus of claim 17 , wherein during rotation therapy a first bladder of the rotation therapy device inflates and a second bladder deflates.
19. The support apparatus of claim 13 , wherein during rotation therapy a first bladder of the rotation therapy device inflates and a second bladder deflates.
