Abstract

The volume clamp method is a kind of non-invasive continuous blood pressure measurement methods, the traditional method is to convert light into a weak current to collect the signal of blood volume pulse by a sensor. In the process of signal transmission, it can be easily disturbed. We adopt a new method, the light is converted into frequency signal, by adopting a suitable method of frequency measurement, we can obtain blood volume pulse. This method improves anti-interference in the process of signal transmission, removes amplifier circuit and filter circuit. Meanwhile, this method also improves the measurement accuracy and real-time of system. On the other hand, due to removing AD, we reduce the cost of system. At the end of this paper, we set up a hardware platform to respectively acquire blood volume pulse with the traditional method and our new method, the results show: the blood volume pulse with our new method is better than that with traditional method.
