Abstract

The present disclosure relates to patient support systems, such as hospital beds, and particularly to reconfigurable patient support systems movable among a number of different positions. The present disclosure further relates to control algorithms and interfaces for use in patient support systems.

First claim

What is claimed is:

1. A patient support system comprising
a support surface including a head-support bladder, a seat-support bladder, and a foot-support bladder,
an air source coupled to the head-support bladder, the seat-support bladder, and the foot support bladder,
a scale system configured to determine a weight of a patient supported on the support surface, and
a controller coupled to the air source and configured to inflate the head-support bladder to a head-bladder egress pressure and to inflate the foot-support bladder to a foot-bladder egress pressure in response to a user pressing a single side-egress button associated with patient exit from the patient support system along a longitudinal side of the support surface that extends from a head end of the support surface to a foot end of the support surface, the head-bladder egress pressure and the foot-bladder egress pressures based, at least in part, on the weight of the patient received by the controller from the scale system associated with the patient support system, wherein the controller is configured to inflate the seat-support bladder to a seat-bladder egress pressure in response to the user pressing the side-egress button, and wherein the controller is configured to inflate the head-support bladder to the head-bladder egress pressure and to inflate the foot-support bladder to the foot-bladder egress pressure before the seat-support bladder is inflated to the seat-bladder egress pressure.

2. The patient support system of claim 1 , wherein the seat-bladder egress pressure is based, at least in part, on the weight of the patient associated with the patient support system.

3. The patient support system of claim 1 , further comprising a patient support apparatus including a lower frame, an upper frame, and a lift system coupled to the lower frame and the lower frame to raise and lower the upper frame relative to the lower frame.

4. The patient support system of claim 3 , wherein the controller is coupled to the lift system and is configured to lower the upper frame relative to the lower frame in response to the user pressing the side-egress button.

5. The patient support system of claim 1 , further comprising a patient support apparatus including an articulatable deck that underlies the support surface, the articulatable deck movable between a lie-flat configuration in which a top side of the support surface is generally flat and a plurality of other positions in which the top side of the support surface is not flat.

6. The patient support system of claim 5 , wherein the controller is configured to move the articulatable deck to the lie-flat configuration in response to the user pressing the side-egress button.

7. The patient support system of claim 4 , wherein the controller is configured to inflate the seat-support bladder to a seat-bladder egress pressure in response to receipt of the side-egress request.

8. The patient support system of claim 7 , wherein the seat-bladder egress pressure is based, at least in part, on the weight of the patient associated with the patient support system received by the controller from a scale system associated with the patient support system.

9. The patient support system of claim 7 , wherein the controller is configured to inflate the head-support bladder to the head-bladder egress pressure and to inflate the foot-support bladder to the foot-bladder egress pressure before inflating the seat-support bladder to the seat-bladder egress pressure.

10. A patient support system comprising
a support surface including a head-support bladder, a seat-support bladder, and a foot-support bladder,
an articulatable deck that underlies the support surface,
an air source coupled to the head-support bladder, the seat-support bladder, and the foot support bladder,
a controller coupled to the air source and configured to inflate the head-support bladder to a head-bladder egress pressure and to inflate the foot-support bladder to a foot-bladder egress pressure in response to receipt of a side-egress request provided by a user pressing a single side-egress button associated with patient exit from the patient support system along a longitudinal side of the support surface that extends from a head end of the support surface to a foot end of the support surface, and
wherein, in response to receipt of the side-egress request, the controller is configured to move the articulatable deck to a lie-flat configuration prior to inflating the head-support bladder to the head-bladder egress pressure and the foot-support bladder to the foot-bladder egress pressure.

11. The patient support system of claim 10 , further comprising a patient support apparatus including a lower frame, an upper frame, and a lift system coupled to the lower frame and the lower frame to raise and lower the upper frame relative to the lower frame.

12. The patient support system of claim 11 , wherein the controller is coupled to the lift system and is configured to lower the upper frame relative to the lower frame in response to receipt of the side-egress request.

13. The patient support system of claim 10 , wherein the head-bladder egress pressure and the foot-bladder egress pressures based, at least in part, on the weight of the patient associated with the patient support system received by the controller from a scale system associated with the patient support system.
