A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

A powered wheelchair is operated by sensor-based control pads that include force transducers to produce a variable output signal that is proportional to a varying force applied. The control pad provides an analog-type output that provides a variable speed signal to a controller to operate the wheelchair at a variable speed in both forward/reverse directions and in right or left turning directions.

The present teachings provide for wheelchair including a control module, manual drive controls, a camera, biometric sensors, and an antenna. The control module includes an autonomous drive module configured to autonomously pilot the wheelchair. The biometric sensors are configured to measure biometric information of a user of the wheelchair.

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.

The sleeping-posture-control bed system includes a bed floor including a back-lifting portion for lifting the user's back, a bed-floor support body supporting the bed floor, and a back-lifting driver for lifting the head side of the back-lifting portion. The back-lifting portion includes a back-receiving surface and a head-receiving surface tiltable at different angles. The back-lifting driver lifts the back-receiving surface and the head-receiving surface, satisfying Mathematical Formula (1):
0°<θx≦70°,−45°≦θy<0°, and −30°≦θx+θy  (1) where θx is the tilt angle of the back-receiving surface when tilted, and the tilt angle of the back-receiving surface when the back-receiving surface is not lifted is set to be 0°; and θy is the tilt angle of the head-receiving surface when the angle of an extended line of the back-receiving surface at the tilt angle θx is referred to as 0°.

Provided herein is a portable surgical system designed for interoperability with surgical or research tools and processes. The portable surgical system may comprise a portable enclosure and one or more sensors. Also provided herein are methods for training surgery robots for use with the system and manufacturing the portable surgical system.

A patient compliance monitoring system is provided for monitoring patient compliance in the use of a plurality of patient care and recovery devices in the hospital room. Sensors are associated with each of the devices to detect a usage history of the associated device and to generate usage data therefore. One device is a patient positioning device including a wedge-shaped body with at least one pressure sensor associated with the bottom surface. The wedge-shaped body is formed of a compressible viscoelastic open-cell foam composition that is adapted to compress under the weight so that the angle of the ramp surface of the wedge decreases from an initial ramp angle to a tilt angle for supporting the patient.

A method for adjusting the pressure of one or more cushions in a human transport system is disclosed. The one or more cushions include a plurality of inflatable chambers and a plurality of pressure sensors associated with the cushions. The pressure sensors may be surface pressure sensors or chamber pressure sensors. A processor associated with the human transport system obtains pressure measurements from the plurality of pressure sensors. Based on the pressure measurements, the processor identifies one or more of the plurality of inflatable chambers whose pressure requirements adjustment. The processor then sends commands that cause the human transport system to adjust the pressure in the one or more inflatable chambers. Systems including cushions and processors are also disclosed.

An incontinence detection alert system may include a bed configured to receive an occupant and at least one monitor configured to acquire data related to at least one of a status of the bed or a status of the occupant. An incontinence detection system may have circuitry to detect an incontinence event of the occupant. A controller may be configured to receive the data from the at least one monitor and to further receive data related to a time of the incontinence event. A remote device may be configured to receive an alert from the controller before a predicted time of a future incontinence event.
