Patent ID: 8226293

Claim:
A temperature sensing device for measuring temperature of a sterile medical fluid comprising: a medical fluid container to house a sterile medical fluid; a fluid line coupled to said medical fluid container to receive said sterile medical fluid therefrom and direct said medical fluid toward a patient; a thermal treatment device proximate said fluid line and operable to thermally treat said sterile medical fluid proximate said thermal treatment device; a conduit member disposed at a selected location along said fluid line and including; a first open end and a second open end, each end being directly securable to selected portions of said fluid line; and an elongated non-linear tubular body extending between said first and second open ends and forming a non-linear flow path for said sterile medical fluid flowing within said fluid line, wherein said non-linear tubular body includes at least one curved section and a thermally conductive flow member directing flow of and in contact with said sterile medical fluid within said at least one curved section; a temperature sensor disposed proximate said thermally conductive flow member to measure temperature through said thermally conductive flow member of said sterile medical fluid within said at least one curved section and to generate an electrical temperature signal indicating said measured fluid temperature; and a controller coupled to said temperature sensor and said thermal treatment device to control said thermal treatment device to thermally treat said medical fluid to attain a desired temperature based on said measured fluid temperature.
