Application of non-contact temperature detection to blood purification technology

On the basis of analyzing several defects in traditional techniques of warming blood, this paper proposed a kind of non-contact temperature measurement and flat-style indirect warming technique, expounded the working principle of non-contact temperature measurement and indirect warming, put forward the structural design of the system, and analyzed key components such as detecting circuit, infrared temperature detecting sensor, in vitro circulation loop and fluid circulation loop. Experimental results indicate that the application of this technique is helpful to raise detecting and controlling accuracy for the improvement of traditional blood purification system, thus improving patients mental status in clinic application and eliminating other complications resulting from blood purification.
