Abstract
Systems for dense phase transport of frozen and other particles to the respiratory system include a particle source, a delivery chamber for metering boluses of the particles from the source, and a transfer tube for fluidized transport of the particles to a patient interface. A controller may be provided to adjust the rate and amount of the bolus deliver to a patient to control core body temperature and for other purposes.
Claims21
A method for producing a series of frozen solid particle (FSP) boluses for delivery to a patient interface, said method comprising:
- (a) providing a source of FSP;
- (b) transferring a metered bolus of FSP from the source into a delivery chamber;
- (c) fluidizing the metered bolus of FSP;
- (d) transferring the fluidized metered bolus of FSP to the patient interface;
- and
- (e) repeating steps (b) through (d) to deliver a series of discrete FSP boluses into the patient interface.
19-44. (canceled)
A system for producing a fluidized metered bolus of frozen solid particle (FSP), said system comprising:
- a source of FSP;
- a delivery chamber configured to receive a metered bolus of FSP from the source;
- a transfer tube having an inlet end configured to receive the metered bolus of FSP from the delivery chamber and an outlet end;
- and
- a fluidizer operatively coupled to the delivery chamber and/or the transfer tube and to transfer the fluidized metered bolus of FSP through the transfer tube.
- wherein the outlet end of the transfer tube is configured to be coupled to a patient interface.
