Abstract: A system for automatically detecting medical devices positioned within a room of a healthcare facility includes a patient support apparatus, a headwall unit, and a controller. The patient support apparatus includes at least first and second transceivers and the headwall unit includes at least third and fourth transceivers. At least one of the first and second transceiver and at least one of the third and fourth transceivers are controller to determine first and second estimates of distance between the respective transceiver and a medical device. The controller uses the first and second estimates of distance to determine if the medical device is positioned within a threshold distance of the patient support apparatus and/or within a predetermined volume of space within the room. The transceivers used to determine the first and second estimates of distance may be Bluetooth Low Energy transceivers and/or ultra-wideband transceivers.

Abstract: A wireless communication system for exchanging messages between a patient support apparatus and a headwall unit includes a syncing function wherein certain settings that are present in the headwall unit before a communication link is established with the patient support apparatus are synced with values for those settings that come from the patient support apparatus after the communication link is initially established. Similarly, certain settings that are present in the patient support apparatus before the communication link is established are synced with values for those settings that come from the headwall unit after the communication link is initially established. The syncing function thereby ensures that, upon the initial establishment of the communication link, the patient support apparatus settings will match the headwall settings, and vice versa.

Abstract: A wireless communication system for exchanging messages between a patient support apparatus and a headwall unit includes intelligence built into either or both of these devices (and/or a server) for detecting when a mismatch occurs between the communication capabilities of the patient support apparatus and those of the headwall unit. A warning is issued in those situations where a caregiver is relying on communication abilities that are not present in one or both of the devices. Examples of such situations include, but are not limited to, a nurse call cable not being coupled between the patient support apparatus and the nurse call system when the patient support apparatus does not have the capability to wirelessly communicate with the nurse call system. Alternatively, or additionally, the headwall unit may issue an alert to a nurse call system if it detects one or more conditions that warrant immediate caregiver attention.

Abstract: A stationary communication unit is adapted to be mounted to a headwall of a healthcare facility and enable wireless communication between a patient support apparatus and a nurse call system. The unit also performs one or more additional functions, such as, but not limited to: determining when a healthcare worker enters/exits the room; determining when the patient support apparatus exits/enters the room; storing/retrieving medical device data associated with a patient; directing medical device data to one or more displays in the room; auto-updating, auto-retrieving, and/or auto-displaying data upon healthcare worker entry into the room; auto-muting room sounds during nurse-patient communication; and auto-directing a healthcare workers electronic device to data associated with the patient in that room. In alternative embodiments, one or more of these additional functions are incorporated into a patient support apparatus.

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, 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.

CPC classification number: G16H40/67 , H04L63/061
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.
