Abstract: A thermal control unit for delivering temperature-controlled fluid to one or more patient therapy devices (e.g. pads, blankets, etc.) that are in contact with a patient is disclosed. The thermal control unit allows multiple patient therapy devices to be fluidly coupled thereto and to individually monitor the temperatures, flow rates, and/or connections/disconnections of the patient therapy devices. A user interface enables a user to designate outlet ports to the therapy devices as active or inactive, and the control unit provides notifications to the user if any of the active ports experience an undesired condition, or if a patient therapy device is connected to an inactive port. The user interface further allows the user to designate one of multiple patient temperature probes as a primary probe. The primary probe is used to control the temperature of the fluid circulating through the control unit.

Abstract: A thermal control unit supplies temperature controlled fluid to one or more thermal pads used to control the temperature of a patient. The thermal control unit includes a fluid outlet, fluid inlet, heat exchanger, pump, and a controller. The controller receives first and second data from at least two different sources to determine if the patient is shivering or not. The two different sources may include a temperature sensor adapted to detect a temperature of the fluid, a temperature sensor adapted to detect a temperature of the patient, a tissue oxygenation sensor, a vibration/motion sensor, a thermal image sensor, an electromyograph, and/or other sensors. In some embodiments, the thermal control unit takes one or more automatic actions in response to detection of patient shivering.

Abstract: A thermal control system for controlling a patient's temperature includes a thermal control unit and an off-board computing device. The thermal control unit includes a fluid inlet, a fluid outlet, a pump, a heat exchanger, a display, one or more sensors, a transceiver, and a controller.

The machine learning techniques may be implemented onboard the thermal control unit and/or may be implemented at a remote computing device (e.g. a server) that collates and analyzes data from multiple thermal control units, and then sends the results of the analyses back to the thermal control units.

Abstract: A medical device, such as a patient support apparatus or a thermal control unit, includes a plurality of mechanical components and a plurality of nodes adapted to communicate with each other over a local network onboard the medical device, and a gateway in communication with an off-board network. The gateway translates messages between the onboard and off-board networks, manages subscriptions to content of the local network, controls bidirectional communication, and otherwise oversees communications between the local and remote networks. The gateway utilizes a configuration file for managing the communications between the off-board and onboard networks, and the gateway is configured to switch to using new or modified configuration files without requiring a reboot or power cycle of the gateway. Updates to the communications between the onboard and off-board networks can therefore be implemented without any downtime and/or without requiring updates to software executables.

Abstract: A thermal control unit supplies temperature controlled fluid to a patient to control the patient's temperature. The thermal control unit includes a fluid outlet, fluid inlet, heat exchanger, pump, patient core temperature probe port, auxiliary sensor port, and controller. The controller receives patient core temperature readings from the patient temperature probe port and auxiliary sensor readings from the auxiliary sensor port. The controller may control a temperature of the circulating fluid in both a feedback manner using patient core temperature readings and a feedforward manner using readings from the auxiliary sensor. The auxiliary sensor may measure a characteristic of the patient's tissue indicative of thermal resistance, and/or the auxiliary sensor may measure a temperature of the patient's tissue at an intermediate depth. The controller may use the intermediate temperature to predict arrival at a target patient temperature.

Abstract: Patient care devices, such as person support apparatuses and thermal control units, include multiple internal network nodes. A controller is associated with each node and at least one of the controllers is adapted to process a message received from another node, convert the message from a first communication protocol to a different communication protocol, and forward the message to yet another node using the different communication protocol. One or more of the controllers may also or alternatively reformulate a packet received in a first format from a first node and forward the reformulated packet to another node. One or more controllers may also send messages over a common data link layer wherein some of the messages are formatted according to different message protocols. Some controllers may utilize real time operating systems while others may not.

Abstract: A thermal control unit controls the temperature of a fluid delivered to one or more thermal transfer devices (e.g. thermal pads) in contact with a patient. The thermal control unit generates thermal data while being used to treat the patient and is adapted to receive thermal history data previously generated by a different thermal control unit in the treatment of that patient. Both the current and previous thermal data are displayable on the thermal control unit currently being used, thereby giving the caregiver a complete picture of the thermal history of the patient. The thermal control unit may also be adapted to transmit its thermal data, as well as the thermal history data previously received from the other thermal control unit, to still another thermal control unit. The thermal history data transfer may take place via a cable, wirelessly, by a portable flash drive, or by other means.
