考虑利用液晶的压力传感作用设计一种血压导管。该系统在光学纤维的一端包有少量的液晶。纤维同时用作入射光和从液晶的反射光的导管。如果将纤维引入静脉和动脉中,反射光的强弱便取决于作用在纤维末端的压力,也就是取决于血压。这样就可以在原地进行测量,因为系统已小型化。 Consider the use of liquid crystal pressure sensing role in the design of a blood pressure catheter. The system contains a small amount of liquid crystal at one end of the optical fiber. Fiber serves as both a conduit for incident light and light reflected from the liquid crystal. If fibers are introduced into the veins and arteries, the intensity of the reflected light depends on the pressure acting on the ends of the fibers, that is, on the blood pressure. This makes it possible to make measurements in situ because the system has been miniaturized.
