Method and apparatus for controlling pressurized infusion and temperature of infused liquids
First Claim
1. A system for controlling pressurized infusion and temperature of intravenous fluids comprising:
- a housing including a housing exterior surface with a recessed portion;
a heating assembly disposed along said recessed portion of said housing exterior surface to heat an intravenous fluid container to a desired temperature;
a flexible cover to wrap around and conform to a portion of said fluid container to secure said fluid container against said recessed heating assembly;
a pressurization member to apply a desired pressure to said fluid container and control a flow rate of intravenous fluid from said fluid container to a patient; and
a controller to control at least one of said heating assembly and said pressurization member.

Abstract
A system for controlling pressurized infusion and temperature of intravenous fluids according to the present invention includes a housing, a heating assembly and a flexible cover. The heating assembly is recessed within the housing and includes a generally U-shaped configuration to surround and uniformly heat fluid within a fluid container placed thereon. The cover wraps around a portion of the fluid container to secure the fluid container against the heating assembly. The cover includes a pressurization member to apply a desired pressure to the fluid container to achieve a desired flow rate of intravenous fluid from the fluid container to an infusion site on a patient. The system further includes a controller to control the heating assembly and pressure within the pressurization member in accordance with desired temperature and pressure information entered into the controller for system operation.
