Abstract
A temperature sensing device for use in a fluid flow system for accurately sensing the temperature of fluid delivered through a lumen of a housing of the device. A temperature sensor element is isolated from the fluid in the lumen by its reception in an enclosure extending through a portion of the wall of the housing into the lumen. The temperature sensor is provided in association with a connector including suitable leads for transferring the electrically generated signal from the sensor to a cable connected to a computer for use in making thermodilution determinations. By permitting the expensive temperature sensor structure to be reusable without the need for repeated sterilization thereof while permitting the flow-through housing to be disposable, long, troublefree life at low cost is provided.
