Thermal Control System

摘要

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.

主权项

1. A thermal control unit comprising:
a first fluid outlet adapted to fluidly couple to a first fluid supply line; a second fluid outlet adapted to fluidly couple to a second fluid supply line; a first fluid inlet adapted to fluidly couple to a first fluid return line; a second fluid inlet adapted to fluidly couple to a second fluid return line; a heat exchanger; a pump for circulating fluid from the first and second fluid inlets through the heat exchanger and to the first and second fluid outlets; a sensing subsystem adapted to detect if the first fluid outlet becomes disconnected from the first fluid supply line and if the second fluid outlet becomes disconnected from the second fluid supply line; and a controller in communication with the pump, the heat exchanger, and the sensing subsystem, the controller adapted to provide an indication to a user if the first fluid outlet becomes disconnected from the first fluid supply line, or the second fluid outlet become disconnected from the second fluid supply line.
