    摘要： Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette of any one of several disclosed variations is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within one of various described re-usable control units. The control units include a heater/cooler device, a user input device, and a processor connected to receive input from various sensors around the body and the system. The heater/cooler device may be thermoelectric to enable both heating and 15″ cooling based on polarity. A temperature control scheme for ramping the body temperature up or down without overshoot is provided. The disposable heat exchange cassettes may include an integral pump head that engages with a pump drive mechanism within the re-usable control unit. More than one control unit may be provided to receive the same heat exchange cassette so that, for example, a large capacity control unit can be used initially, and a smaller, battery-powered unit can be substituted once the patient reaches the desired target temperature.

    摘要翻译： 包括诱导低温的状态的患者的温度改变方法和装置，或其选定区域。 使用在其中流体热交换介质循环的内部热交换导管来实现温度改变。 几个公开的变型中的任何一个的热交换盒附接到导管的循环导管，热交换盒的尺寸适于接合各种所描述的可重复使用的控制单元之一内的空腔。 控制单元包括加热器/冷却器装置，用户输入装置和连接以接收来自身体和系统周围的各种传感器的输入的处理器。 加热器/冷却器装置可以是热电，以使得能够基于极性进行加热和15“冷却。 提供了一种用于使体温上升或下降而没有过冲的温度控制方案。 一次性热交换盒可以包括与可再使用的控制单元内的泵驱动机构接合的整体泵头。 可以提供多于一个控制单元以接收相同的热交换盒，使得例如最初可以使用大容量控制单元，并且一旦患者达到期望的目标温度，可以取代较小的电池供电的单元 。
