Development of a noninvasive instantaneous blood pressure measurement device based on volume-compensation method and study of its control algorithm

Abstract

An instantaneous blood pressure measurement device based on volume compensation was developed, and a measurement control method was tested and improved on the device. The device consists of a cylindrical finger cuff, a compact proportional solenoid valve, an air pump and a hardware circuit. Finger cuff contains a pair of led and photo-diode. The hardware circuit consists of a feedback controls circuit and a signal processing circuit based on a microprocessor controller. A neural network predictive controller is proposed to replace the traditional PID controller for experiments. Simulation and experiments show that the neural network predictive controller has better control effect than the traditional PID controller.

Implementation of a home-made high accuracy pulsimeter and oximeter

“…In fact, prevalent cases of cardiovascular diseases have doubled worldwide in the last 30 years [8]. Therefore, the development of fast and non-invasive devices to monitor the cardiovascular activity has attracted great attention [9][10][11]. A clear example of the effectiveness of this type of devices has been the SARS-CoV-2 pandemic, where the peripheral capillary oxygen saturation (SpO 2 ) was a critical parameter for monitoring this disease in patients [12,13].…”

Blood pressure monitoring techniques in the natural state of multi-scenes: A review

“…volume clamp method, the control algorithms are improving. Chen and Chen(28) proposed a neural network predictive controller to replace the traditional Proportional-integralderivative (PID) controller. Fortin et al(29) proposed an innovative continuous non-invasive hemodynamic monitoring technology (CNAP2GO).…”
