A patient support apparatus comprises a plurality of load cells, a frame, a mattress, a plurality sensors, and a control system. The mattress includes a plurality of inflatable zones positioned on the frame, the mattress and frame cooperating to direct any patient load through the mattress and frame to the load cells. Each of the plurality of a sensors measures the pressure in a respective inflatable zone of the mattress. The control system includes a controller operable to receive a separate signal from each of the plurality of sensors, and a physiological sensor, process the signals to identify movement data and sleep data and to display the movement data and sleep date on a segmented screen on a user interface.

A patient support apparatus includes a plurality of primary sensors adapted to measure different parameters used in the control of the patient support apparatus. One or more suites of secondary sensors are added to the patient support apparatus to provide data about the primary sensors. The secondary sensors may be used to detect errors in the primary sensors, to modify outputs from the primary sensors, and/or to provide usage and/or diagnostic data about the use of the patient support apparatus. The suite(s) of secondary sensors may measure parameters that affect the outputs of one or more of the primary sensors. In some embodiments, the suite(s) of secondary sensors include one or more dormant sensors that are not used on the patient support apparatus until a code modification is received from one or more external sources instructing the control system of the patient support apparatus to begin using the dormant sensor(s).

A patient immersion sensor includes a radio detection and ranging (RADAR) apparatus to determine a time of flight (TOF) of a RADAR pulse and a reflected signal that is reflected by a patient or by a portion of a patient support surface supporting the patient. The TOF is indicative of an immersion depth or a distance toward bottoming out of a patient supported on the patient support surface, such as a mattress or a pad. The RADAR apparatus emits pulses of very short duration so as to be able to detect objects, such as a patient or a portion of a mattress or pad, at very close distances. The RADAR apparatus may use time-of-flight (TOF) between transmission of the pulse and receipt of a reflected signal to determine a distance toward bottoming out by the patient, thereby to determine if the patient is properly immersed into the patient support surface. Adjustments to inflation or deflation of one or more bladders are made to achieve a desired immersion amount within a tolerance range between upper and lower TOF thresholds.

Overhead lift units are disclosed. In one embodiment, an overhead lift unit includes a carriage having wheels engageable with a rail, a lift frame coupled to the carriage such that the lift frame is suspended from the carriage, and a pair of load beams. The lift frame includes a lift strap extending from the lift frame and a pair of connection points extending from the lift frame. Each load beam of the pair of load beams is attached to one connection point of the pair of connection points of the lift frame at an inferior end of the load beam. Each load beam of the pair of load beams is attached to the carriage at a superior end of the load beam. And each load beam of the pair of load beams comprises a strain gauge operable to register a weight supported on the lift strap.

A lift device and method of operation thereof including two vertical extendible tower members supporting a horizontal extendible transverse member, a payload lifting device and a traveler carriage configured to translate the payload between the two vertical extendible tower members along the horizontal extendible transverse member, an omnidirectional wheel assembly, a navigation control system configured to provide navigation control to the lift device via the omnidirectional wheel assembly based on a navigation path, one of a proximity sensing system and a machine vision system configured to determine one of a presence of an obstacle or an absence of a previously detected obstacle relative to the navigation path, and a motion control system configured to provide a smooth motion control signal and a retract or expand signal to the respective members of the lift device.

A toilet comprising a frame; a bowl supported by the frame; a seat also supported by the frame; a shroud for covering the frame; at least one lift mechanism supported by the frame for adjusting the position of the bowl or seat; at least one sensor for capturing at least one property of a user; and a processor adapted to analyze the at least one property to determine a characteristic of the user is disclosed.

A patient transport apparatus comprising a support frame, a base, a bracket coupled to the support frame and comprising a channel being non-linear, a frame assembly coupled between the support frame and the base and comprising a slidable member disposed in the channel, the slidable member being moveable between a plurality of different positions in the channel to place the support frame in a plurality of different poses relative to the base. The patient transport apparatus also comprises a sensor configured to detect the slidable member in the channel and produce a reading, as well as a controller coupled to the sensor and configured to receive the reading from the sensor, determine the position of the slidable member in the channel based on the reading, and determine the pose of the support frame relative to the base based on the determined position of the slidable member.

An ambulance cot loading and unloading system for an emergency vehicle includes a base for mounting in the emergency vehicle and an arm mounted for linear movement along the base, wherein the arm configured to support a cot while the cot is being loaded into or unloaded from the emergency vehicle. The ambulance cot loading and unloading system further includes an indicator mounted relative to the arm and a control system, which is in communication with the indicator and configured to generate a status indication of the cot loading and unloading system at the indicator.

This disclosure generally relates to systems and methods for detecting, monitoring, and responding to abnormalities in a subject's breathing or heartbeat. One or more sensing devices may collect breathing or heartbeat related data, which may be filtered and converted to a frequency signal. The frequency signal may be monitored for irregularity or stoppage, and a processing module may determine whether the irregularity or stoppage is caused by an actual stoppage or irregularity in breathing or heartbeat. If breathing or heartbeat is determined to have stopped, a corrective action may be performed.

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.
