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.

Patient transport apparatus having powered drive system utilizing dual mode user input control

A thermal control unit for controlling a patient's temperature includes a fluid outlet for delivering temperature-controlled fluid to a patient, a pump, a heat exchanger, and a controller that automatically pauses thermal treatment of the patient prior the patient reaching a target temperature. During the pause, the controller assesses a reaction of the patient and changes a temperature of the fluid only inside the thermal control unit if the patient is likely to reach the target temperature without further thermal treatment. However, if the patient is unlikely to reach the target temperature without further thermal treatment, the controller restarts the thermal treatment. The controller may pause thermal treatment again prior to reaching the target temperature and assess the patient's reaction. In some embodiments, the controller may selectively include and exclude a fluid reservoir in a circulation channel within the thermal control unit.

Thermal system with overshoot reduction

A thermal control unit for controlling a patient's temperature includes a fluid outlet for delivering temperature-controlled fluid to a patient, a pump, a heat exchanger, a controller, and a user interface that displays a graph of patient temperature readings over time. The user interface also displays one or more event icons on the graph at locations corresponding to the time at which events associated with the event icons occurred. In some embodiments, the graph is displayed on a touch screen adapted to allow a user set maximum and minimum permissible temperatures for the fluid by touching areas of the graphs and/or by drawing on certain areas of the graph. An image of a human body having different zones may also be displayed on the user interface along with information pertaining to the thermal therapy being applied to the corresponding zones of the patient's body.

Thermal system with graphical user interface

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 temperature probe port, user interface, and controller. The controller receives patient temperature readings from the patient temperature probe port and controls a temperature of the circulating fluid in a first manner when no event data is received regarding treatment of the patient. The controller controls a temperature of the circulating fluid in a second and different manner when event data is received. The event data may relate to medication and/or fluid administered to the patient. The different manners include determining a target fluid temperature in using different inputs and/or alarming in different manners. In some cases, the controller pauses the use of the patient temperature readings while continuing to deliver temperature controlled fluid to the patient.

Thermal system with medication interaction

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.

Thermal system

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 includes a fluid circuit with an inlet and outlet, a reservoir, a heat exchanger, a pump, and a controller. The thermal control also includes any one or more of the following: (1) an air eliminator with an air filter for filtering air vented from the fluid circuit to the ambient surroundings; (2) a plug that moves in response to changing fluid levels and that fluidly isolates the air filter from the fluid; (3) a second air filter coupled to the reservoir; (4) a check valve to prevent fluid from back flowing into the reservoir; and/or (5) a liquid filter coupleable to the reservoir to filter liquid entering or exiting the reservoir.

Thermal control system

A temperature management device for warming or cooling a person's body includes a device body, which has a fluid conduit for flowing fluid through the device body. The device body includes a contact surface to face and contact the person's body on which the device body is applied and is configured to conform to the person's body wherein the contact surface contacts the person's body and follows a surface topography of the person's body, and further provides a thermally conductive surface for transmitting thermal energy from the fluid flowing through the fluid conduit to the person's body.

Thermal treatment devices

A thermal transfer device for providing thermal treatment to a patient. A patient support portion supporting and contacting the patient includes a first segment of a fluid flow path to receive a fluid from a fluid source. A flexible covering coupled and movable relative to the patient support portion defines a space therebetween that substantially conforms to the patient. The flexible covering includes a second segment of the fluid flow path. The fluid is circulated through an inlet, an outlet, and fluid flow path for supplying heat to or removing heat from the patient support portion and the flexible covering. A fluid circulation system with a controller may selectively adjust heat transfer from temperature zones defining the patient support portion. The thermal transfer device or a mattress cover may provide for controlling the microclimate, or conditions at or near the interface between the patient and the patient support portion.

Thermal transfer device for providing thermal treatment to a patient

A thermal control unit for controlling a patient's temperature includes a fluid outlet for delivering temperature-controlled fluid to a patient, a pump, a heat exchanger, and a controller that automatically implements a step change in the temperature of the fluid delivered to the patient. The step change is implemented prior to the patient reaching a target patient temperature. In the moments after (and in some cases the moments before) the step change, the controller monitors the rate of change of patient's temperature to evaluate whether the patient will reach the target patient temperature without reversing the step change, and/or how long it will likely take for the patient to reach the target patient temperature without reversing the step change. The controller then determines whether to reverse the step change or to switch to another algorithm for controlling the fluid temperature.

Thermal system with step response

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.
