Pulmonary mattress
First Claim
1. A patient-support apparatus comprisingan upper frame having a head end and a foot end, the upper frame movable between a generally horizontal position and a position wherein the head end of the upper frame is spaced vertically below the foot end of the upper frame,an upper deck supported on the upper frame, the upper deck movable with the upper frame and including a seat section and a head section, the head section pivotable relative to the seat section to change the angular relationship between the head section and the seat section,a controller controlling movement of the upper frame and the head section of the upper deck such that when the head section of the upper deck moves from a first, horizontal position sensed by an angle sensor in which the head section is generally coplanar with the seat section to a second, non-horizontal position sensed by the angle sensor in which the head section is inclined, the controller causes the upper frame to move from the generally horizontal position to a first position wherein the head end of the upper frame is lowered, and wherein continued articulation of the head section upwardly to a third, non-horizontal position sensed by the angle sensor causes the controller to move the upper frame from the first position back to the generally horizontal position, anda mattress including a coverlet including (i) an entry positioned at a first end of the coverlet, (ii) an exit positioned at a second end of the coverlet opposite the entry, (iii) an upper air impermeable layer, and (iv) a lower air impermeable layer coupled to the upper layer to form an air flow path along the length of the coverlet, the flow path providing communication between the entry and the exit,wherein the upper air impermeable layer is vapor permeable and water resistant fabric, the lower air impermeable layer is vapor permeable and water resistant fabric, and the coverlet further comprises a spacer fabric interposed between the upper and lower layers to facilitate air flow through the coverlet.

Abstract
A patient-support apparatus includes a mattress assembly supported on a frame, the mattress assembly including a coverlet configured to provide low-airloss therapy to a patient supported on the patient-support apparatus. The patient-support apparatus is articulable to a number of positions and includes a control network which is responsive to movement of portions of the frame to alter operational parameters of the frame and mattress assembly.

1. A patient-support apparatus comprising
an upper frame having a head end and a foot end, the upper frame movable between a generally horizontal position and a position wherein the head end of the upper frame is spaced vertically below the foot end of the upper frame, an upper deck supported on the upper frame, the upper deck movable with the upper frame and including a seat section and a head section, the head section pivotable relative to the seat section to change the angular relationship between the head section and the seat section, a controller controlling movement of the upper frame and the head section of the upper deck such that when the head section of the upper deck moves from a first, horizontal position sensed by an angle sensor in which the head section is generally coplanar with the seat section to a second, non-horizontal position sensed by the angle sensor in which the head section is inclined, the controller causes the upper frame to move from the generally horizontal position to a first position wherein the head end of the upper frame is lowered, and wherein continued articulation of the head section upwardly to a third, non-horizontal position sensed by the angle sensor causes the controller to move the upper frame from the first position back to the generally horizontal position, and a mattress including a coverlet including (i) an entry positioned at a first end of the coverlet, (ii) an exit positioned at a second end of the coverlet opposite the entry, (iii) an upper air impermeable layer, and (iv) a lower air impermeable layer coupled to the upper layer to form an air flow path along the length of the coverlet, the flow path providing communication between the entry and the exit, wherein the upper air impermeable layer is vapor permeable and water resistant fabric, the lower air impermeable layer is vapor permeable and water resistant fabric, and the coverlet further comprises a spacer fabric interposed between the upper and lower layers to facilitate air flow through the coverlet.

19. A patient-support apparatus comprising
an upper frame having a head end and a foot end, the upper frame movable between a generally horizontal position and a position wherein the head end of the upper frame is spaced vertically below the foot end of the upper frame, an upper deck supported on the upper frame, the upper deck movable with the upper frame and including a seat section and a head section, the head section pivotable relative to the seat section to change the angular relationship between the head section and the seat section, a mattress including a coverlet including (i) an entry positioned at a first end of the coverlet, (ii) an exit positioned at a second end of the coverlet opposite the entry, (iii) an upper air impermeable layer, and (iv) a lower air impermeable layer coupled to the upper layer to form an air flow path along the length of the coverlet, the flow path providing communication between the entry and the exit, a control system including a peer-to-peer network and a controller controlling movement of the upper frame and the head section of the upper deck such that when the head section of the upper deck moves from a first, horizontal position sensed by an angle sensor in which the head section is generally coplanar with the seat section to a second, non-horizontal position sensed by the angle sensor in which the head section is inclined, the controller causes the upper frame to move from the generally horizontal position to a first position wherein the head end of the upper frame is lowered, and wherein continued articulation of the head section upwardly to a third, non-horizontal position sensed by the angle sensor causes the controller to move the upper frame from the first position back to the generally horizontal position, a pneumatic supply and control system coupled to the peer-to-peer network, and a control module configured to be removably coupled to the pneumatic supply and control system to control the operation of the coverlet, the control module including (i) a controller communicating with the pneumatic supply and control system, (ii) a plurality of connectors configured to engage the pneumatic supply and control system to receive pressurized air, (iii) an electrical connector configured to engage the pneumatic supply and control system to provide electrical communication between the controller and the pneumatic supply and control system, (iv) a plurality of outputs configured to provide pneumatic communication between the control module and the coverlet, and (v) a plurality of valves responsive to the controller to control a flow of pressurized air from the pneumatic supply and control system to the coverlet.

23. A patient-support apparatus comprising
an upper frame having a head end and a foot end, the upper frame movable between a generally horizontal position and a position wherein the head end of the upper frame is spaced vertically below the foot end of the upper frame, an upper deck supported on the upper frame, the upper deck movable with the upper frame and including a seat section and a head section, the head section pivotable relative to the seat section to change the angular relationship between the head section and the seat section, and a controller controlling movement of the upper frame and the head section of the upper deck such that when the head section of the upper deck moves from a first, horizontal position sensed by an angle sensor in which the head section is generally coplanar with the seat section to a second, non-horizontal position sensed by the angle sensor in which the head section is inclined, the controller causes the upper frame to move from the generally horizontal position to a first position wherein the head end of the upper frame is lowered, and wherein continued articulation of the head section upwardly to a third, non-horizontal position sensed by the angle sensor causes the controller to move the upper frame from the first position back to the generally horizontal position.
