Abstract: A patient support apparatus and a portable service tool are adapted to communicate with each other in order to allow a user of the service tool to wirelessly update software executed by the patient support apparatus. In some embodiments, the patient support apparatus displays a coded message that encodes network credentials (e.g. SSID, password, etc.) and the software tool is adapted to capture an image of the coded message, decode the message, and then set up a wireless network having the decoded network credentials. The patient support apparatus then automatically joins the network and receives one or more wireless software updates. The service tool may alternatively or additionally connect to a healthcare facility network and upload software to a server thereon, which then downloads the software to the patient support apparatus over the healthcare facility computer network.

Abstract: Systems for facilitating movement of a patient transport apparatus are provided and include user input control device that includes a mode switch selectable between a longitudinal transport mode and a multidirectional mode and a driving assist device actuatable between at least one engaged state and a non-engaged state. The mode switch generates signals based on the selected mode and the driving assist device generates engaged or non-engaged signals which are received by a controller. The controller is configured to generate an output signal sent to a lift actuator, swivel actuator, and/or a powered drive system to assist a user in propelling the apparatus in a desired manner.

Abstract: A patient support apparatus includes a frame, a patient support surface, and a nurse call cable interface adapted to communicatively couple to a wall-mounted nurse call outlet having a plurality of pins to thereby allow the patient to communicate with a remotely positioned nurse. One or more sensors are included that detect when the cable is plugged into the nurse call outlet and/or when the bed is communicatively coupled to the nurse call system. The controller may activate an indicator when the sensor detects that the bed is not coupled to the nurse call system outlet, automatically select whether to communicate with the nurse call system via a wireless transceiver or via the nurse call cable interface based on the sensor output, and/or inform the caregiver when a headwall module spaced from the bed is not communicatively coupled to the nurse call system outlet.

Abstract: A patient support apparatus includes a first transceiver adapted to wirelessly communicate with a second transceiver of a headwall interface that is positioned off of the patient support apparatus. A communication link is automatically established between the first and second transceivers without requiring a user of the patient support apparatus to activate a designated control and without requiring the user to identify the headwall interface. The first transceiver includes a unique identifier assigned to the headwall interface in its messages to the headwall interface. The first transceiver may also automatically transmit a disconnect signal to the headwall interface indicating the termination of the communication link is not accidental. The disconnect signal is sent based on one or more of the following: (1) a brake being off, (2) an A/C power cord being unplugged; and/or (3) a signal strength between the transceivers decreasing.

Abstract: A patient support apparatus includes a frame, patient support surface, memory having a first key stored therein, a transceiver, and a controller. The transceiver wirelessly communicates with a medical device over a first mesh network using the first key. The controller transmits a request message over the first mesh network to the medical device via the transceiver. The request message includes an identifier identifying the patient support apparatus and a request to join a second mesh network different from the first mesh network. The controller receives a second key input over the first mesh network, uses the second key input to generate a second key, and to use the second key to communicate over the second mesh network. In some instances, the second key input originates from a cloud-based server storing a list of authorized devices for a particular healthcare facility.

Abstract: A person support apparatus includes a first transceiver adapted to wirelessly communicate with a second transceiver of a headwall interface that is positioned off of the person support apparatus. A communication link is automatically established between the first and second transceivers without requiring a user of the person support apparatus to activate a designated control and without requiring the user to identify the headwall interface. The first transceiver includes a unique identifier assigned to the headwall interface in its messages to the headwall interface. The first transceiver may also automatically transmit a disconnect signal to the headwall interface indicating the termination of the communication link is not accidental. The disconnect signal is sent based on one or more of the following: (1) a brake being off, (2) an A/C power cord being unplugged; and/or (3) a signal strength between the transceivers decreasing.

Abstract: A patient support apparatus, such as a bed, stretcher, cot, operating table, chair, or the like, includes a support surface for an occupant, a user interface, and a control system. The user interface includes multiple sensing layers to detect when a user touches the user interface. The control system activates only a first one of the sensing layers when the patient support apparatus is in a sleep mode, and upon the first sensing layer detecting a user touching the user interface while in the sleep mode, the control system activates that second sensing layer. One of the sensing layers may be resistive and the other capacitive. One of the layers may also detect a position at which the user touches the user interface, while the other layer may only detect that the user interface was touched, but not detect the position of the touch.

Abstract: 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.

Abstract: A patient support, such as a mattress, includes a plurality of inflatable bladders. Depth sensors are included in the support that measure the degree of penetration of a patient into the mattress. An air pressure sensor is also included that measures the pressure inside at least one bladder. A suitable inflation level of the mattress is determined by monitoring the rate of change of the depth with respect to air pressure as the bladder is either inflated or deflated. By detecting an inflection point in the graphical relationship of the depth and pressure outputs, a suitable inflation point for the bladders is determined that reduces interface pressures experienced by the patient, yet does not overly sink the patient into the mattress to a degree of discomfort. Analyzing the outputs of the depth and pressure sensors can also be used to detect a patient's heart rate and respiration rate.
