Abstract
In general, the disclosure presents techniques for control of a cooling garment in response to a signal that is a function of a patient parameter such as body temperature. In particular, a cooling garment that receives a coolant and a carrier gas is placed in contact with the body of a patient. A sensor within the cooling garment may generate a signal as a function of a patient parameter. A controller receives the signal via communication link, and may send a signal to a regulator that may regulate delivery of the coolant and/or carrier gas, for example.
Claims40
A system comprising:
- a cooling garment for contacting a portion of the body of a patient, and having a coolant and a carrier gas for delivery to the body of the patient;
- a sensor within the cooling garment;
- a warm air supply for delivering warm air to the patient;
- and
- a controller for controlling the cooling garment in response to a signal from the sensor and controlling delivery of the warm air.
A method comprising:
- delivering a carrier gas and a coolant to a cooling garment in contact with the body of a patient;
- generating a signal as a function of a patient parameter via a sensor within the cooling garment;
- and
- controlling the cooling garment in response to the generated signal, wherein controlling the cooling garment includes:
- operating the cooling garment to cool the patient at a first rate, and operating the cooling garment to cool the patient at a second rate in response to the generated signal, and wherein operating the cooling garment to cool the patient at a second rate in response to the generated signal includes operating the cooling garment to cool the patient at a second rate in response to a temperature of the patient falling below a frostbite temperature.
A system comprising:
- a coolant supply for supplying coolant to a cooling garment that contacts a portion of a body of a patient;
- a carrier gas supply for supplying carrier gas to the cooling garment;
- a warm air supply for supplying warm air to a body part of the patient when in use;
- and
- a regulator for regulating at least one of the coolant supply, the carrier gas supply and the warm air supply as a function of a patient parameter.
