Abstract

A patient support apparatus includes a frame, a support surface, a caregiver control panel, a patient control panel, and a controller. The caregiver control panel includes a lock out control that, when manually activated by a caregiver, locks out one or more particular controls on the patient control panel. The controller is also adapted to automatically lock out the one or more particular controls, irrespective of the state of the lock out control, in response to a triggering event. The triggering event may include one or more of the following: the arming of an exit detection system, the arming of a monitoring system, the passage of a predetermined time period, the use of a scale, the zeroing of the scale, the receipt of a fall risk score for the patient, etc. The caregiver control panel may allow the caregiver to select what patient controls are automatically locked out.

Claims20

Dependent claims

A patient support apparatus comprising:

a base;
a plurality of lifts;
a frame supported on the lifts, wherein the lifts are adapted to change a height of the frame;
a support surface supported on the frame and adapted to support a patient thereon;
a caregiver control panel including a lockout control adapted to be activated by a caregiver;
a patient control panel including a first control adapted to be activated by the patient, the first control having a locked state and an unlocked state, the first control adapted to move a component of the patient support apparatus when activated while in the unlocked state, the first control adapted to not move the component of the patient support apparatus when activated while in the locked state;
and
a controller in communication with the patient control panel and the caregiver control panel, the controller adapted to change the first control to the locked state in response to the lockout control being manually activated, to also change the first control to the locked state in response to detecting a triggering event, to detect cessation of the triggering event, and in response to detecting the cessation of the triggering event, to perform at least one of the following:
(a) return the first control to the unlocked state if the first control was in the unlocked state prior to detection of the triggering event, or
(b) leave the first control in the locked state if the first control had been activated into the locked state by manual activation of the lockout control prior to detection of the triggering event.

and
a controller in communication with the patient control panel and the caregiver control panel, the controller adapted to automatically activate the lockout control and change the first control to a locked state in response to detecting a triggering event such that—when in the locked state activation of the first control does not move the component, the controller further adapted to perform the following:
to display a first lockout indication for the first control when the lockout control is manually activated by the caregiver,
to display a second lockout indication for the first control when the lockout control is automatically activated in response to the triggering event;
to display neither the first nor second lockout indication when the lockout control is not manually activated by the caregiver and the triggering event is absent, wherein the first lockout indication is different from the second lockout indication;
to detect cessation of the triggering event;
and
in response to detecting the cessation of the triggering event, to perform at least one of the following:
(a) return the first control to an unlocked state if the first control was in the unlocked state prior to detection of the triggering event, or
(b) leave the first control in the locked state if the lockout control had been manually activated prior to detection of the triggering event.
