Development of An Invasive Device for Long-term Remote Monitoring of Cardiovascular System Parameters, Including Blood Pressure, in Patients with Comorbid Conditions

Abstract

The aim of the study is to develop an invasive device for long-term remote monitoring of cardiovascular system parameters, including blood pressure, in patients with comorbid conditions. Such a device is an important solution of a medical problemcontinuous monitoring of patients with hypertension, arrhythmias, chronic heart failure and other comorbid vascular conditions.We developed a pilot model of a device for longterm remote monitoring of blood pressure (systolic, diastolic, mean), heart rate and other calculable parameters of cardiovascular system. We developed a model of a capacitive sensor based on a microelectromechanical system technology (MEMS), equipped with a continuously-adjustable capacitor, wireless data communication and electric power supply. Transmitter model is developed. Engineering tests of device prototype were performed. Experimental work demonstrating the feasibility of converting the collected signals into mm of Hg for the measurement of blood pressure changes and steady radiosignal transduction to the transmitter was performed. A variant of biocompatible cover was chosen-silicone and parylene C. The sensor is designed to be implanted into human or animal body and can be situated either in the vessel lumen or on the vessel wall.

Screening System for Cardiac Problems through Non-Invasive Identification of Blood Pressure Waveform

“…The use of invasive techniques poses particular requirements, since the patient is usually recommended to minimize movements and activities. Stupin et al [8] developed a device providing invasive-type blood pressure remote monitoring. The device uses an implanted capacitive blood pressure sensor with wireless data transmission.…”

Multifunctional Neurodevice for Recognition of Electrophysiological Signals and Data Transmission in an Exoskeleton Construction

“…Today the areas of invasive and noninvasive monitoring of blood circulation system, primarily the monitoring of blood pressure and heart rate (HR), are actively developing. The physiological parameters of the cardiovascular system have a high level of correlation with brain activity, including the performance of motional tasks [17,18]. The results of the study on heart's working in the presence of a changing mental activity measured by using EEG, tell us about the prospects of using such hybrid systems [19,20].…”
