Infusion systems and methods for introducing fluids into the body within a desired temperature range
First Claim
1. A system for infusing a fluid into a patient such that the fluid mixes in vivo with the patient'"'"'s blood so as to warm or cool the patient, the system comprising:
- a volume of fluid within a reservoir;
a temperature sensor which senses the temperature of the fluid in the reservoir;
s a temperature altering device in close proximity to the volume of fluid, said temperature altering device being useable to alternately heat or cool the volume of fluid within the reservoir to a desired temperature;
a positive pressure device to place the volume of fluid within the reservoir under positive pressure while at the desired temperature;
a transfer conduit to transfer at least some of the fluid under positive pressure to the patient while at the desired temperature; and
a processor that is in communication with at least the temperature sensor and the positive pressure device, said processor being operative to cause the positive pressure device to move fluid through the transfer conduit after the fluid has reached a desired temperature and to control the rate and volume of fluid that passes through the transfer conduit.

Abstract
The invention provides systems and methods for infusing a fluid into a patient. In one exemplary embodiment, a system comprises a volume of fluid and a temperature altering device in close proximity to the volume of fluid. The temperature altering device is employed to heat or cool the volume of fluid to a desired temperature. A positive pressure device is provided to place the volume of fluid under positive pressure while at the desired temperature. A transfer member is further provided to transfer at least some of the fluid into the patient while at the desired temperature.
