Abstract
Devices used to sense physiologic blood parameters are disclosed. The devices may be configured to sense at least two physiologic blood parameters at substantially a common site of an extracorporeal perfusion circuit. The devices may include a pressure sensor and a temperature sensor. The temperature sensor may be in direct contact with the blood.
Claims16
A sensor device, comprising:
- a housing comprising a gel well;
- a printed circuit board member;
- a first sensor electrically coupled to the printed circuit board member;
- and
- a second sensor electrically coupled to the printed circuit board member,
- wherein the first sensor is configured to measure a first parameter of a physiologic fluid and the second sensor is configured to measure a second parameter of the physiologic fluid at a common site of a perfusion circuit,
- wherein the first sensor is at least partially disposed within the gel well of the housing, and
- wherein a first end of the first sensor protrudes above a rim of the gel well.
