Blood parameter sensing device with pressure and temperature sensors
A recently granted patent (Publication Number: US11992295B2) discloses a sensor device designed to measure physiologic parameters of a fluid within a perfusion circuit. The device includes a housing with a gel well, a printed circuit board, a first sensor for measuring a parameter of the fluid, and a second sensor for measuring another parameter of the fluid at the same site. The first sensor is partially within the gel well, with one end protruding above the rim, ensuring direct contact with the fluid. The patent also details the materials and configurations of the sensors, such as a temperature sensor with cladding made of various materials like polyimide and stainless steel.
Furthermore, the patent describes a sensor assembly with additional sensors for measuring blood temperature and pressure at the common site of a perfusion circuit. The assembly includes a housing with a gel well, a printed circuit board, a pressure sensor, a temperature sensor, and a connector. The temperature sensor is partially within the gel well, with options for it to be flush with the rim or protruding above it. The patent also outlines a method for measuring physiologic parameters of a fluid using the sensor device, emphasizing the exposure of the device to the fluid and the measurement of temperature and pressure at the common site. Overall, the patent provides a detailed and innovative approach to monitoring physiologic parameters in a fluid within a perfusion circuit, offering potential advancements in medical monitoring technology.
