Abstract

An adjustable patient support apparatus comprises a base, a support frame, and a patient support deck. The patient support deck comprises articulating deck sections, such as a leg section, seat section, and a back section pivotally coupled together. One or more actuators may be configured to move the leg and/or back section between a lowered position and one or more raised positions. The seat section may include one or more articulating seats to assist with ingress and egress from the patient support apparatus. The one or more seats may be articulated manually or electrically via a lever or actuator.

First claim

What is claimed is:

1 . A patient support apparatus comprising:
a base; a patient support deck supported by the base and comprising a deck section having a first portion and a second portion configured to articulate relative to the first portion to transition between a bed configuration and a side-egress configuration, and including a third portion positioned between the first portion and the second portion; an actuator system coupled to the deck section and configured to articulate the second portion; wherein the first portion, the second portion, and the third portion are substantially co-planar when in the bed configuration; and wherein the second portion is configured to articulate relative to the first portion as the actuator system transitions the deck section from the bed configuration to the side-egress configuration.

2 . The patient support apparatus of claim 1 , further comprising a lift mechanism extending from the base and operatively connected to the patient support deck, the lift mechanism configured to raise and lower the patient support deck relative to the base.

3 . The patient support apparatus of claim 2 , further comprising a controller coupled to the lift mechanism and configured to control the lift mechanism to raise the patient support deck relative to the base as the deck section transitions to the side-egress configuration.

4 . The patient support apparatus of claim 3 , wherein the controller is coupled to the actuator system and configured to control articulation of the second portion to transition the deck section from the bed configuration to the side-egress configuration.

5 . The patient support apparatus of claim 4 , wherein the actuator system comprises a first actuator operatively attached to the first portion and a second actuator operatively attached to the second portion.

6 . The patient support apparatus of claim 5 , wherein the controller is configured to operate at least one of the first actuator and the second actuator to articulate the second portion to transition the deck section from the bed configuration to the side-egress configuration.

7 . The patient support apparatus of claim 3 , further comprising a carrier assembly comprising:
a carrier; and a carrier actuator operatively connected to the carrier to move the carrier relative to the base, wherein the carrier is to be positioned adjacent a floor surface as the deck section transitions from the bed configuration to the side-egress configuration to support a patient.

8 . The patient support apparatus of claim 7 , wherein the controller is coupled to the carrier actuator and configured to coordinate movement of the carrier with articulation of the second portion.

9 . The patient support apparatus of claim 8 , wherein the carrier assembly further comprises a sensor attached proximate to the carrier to detect contact between the patient and the carrier.

10 . The patient support apparatus of claim 9 , wherein the sensor is one of a load cell, weight sensor, pressure sensor, optical sensor, infrared sensor, or motion sensor.

11 . The patient support apparatus of claim 7 , wherein the controller is coupled to the carrier actuator and configured to coordinate movement of the carrier with the articulation of the second portion and raising of the patient support deck.

12 . The patient support apparatus of claim 1 , wherein the first portion and the second portion comprise mating features configured to define a saddle to support a patient when the deck section is transitioning to the side-egress configuration.

13 . The patient support apparatus of claim 1 , further comprising a support belt attached to the deck section, the support belt configured to extend across the deck section and secure a patient when the deck section transitions from the bed configuration to the side-egress configuration.

14 . The patient support apparatus of claim 1 , wherein the first portion is configured to articulate relative to the second portion to transition between the bed configuration and the side-egress configuration.

15 . The patient support apparatus of claim 1 , further comprising:
a lift mechanism extending from the base and operatively connected to the patient support deck, the lift mechanism configured to raise and lower the patient support deck relative to the base; a controller coupled to the lift mechanism and configured to control the lift mechanism to raise the patient support deck relative to the base as the deck section transitions to the side-egress configuration; and wherein the controller is coupled to the actuator system and configured to control articulation of the first portion and the second portion to transition the deck section between the bed configuration and the side-egress configuration.

16 . The patient support apparatus of claim 15 , wherein the controller is configured to control the actuator system to articulate the first portion in a generally upward direction relative to the third portion, articulate the second portion in a generally downward direction relative to the third portion, with the third portion remaining substantially horizontal when transitioning the deck section to the side-egress configuration.
