Device for recording the physiological parameters of the patient and its position in three-dimensional space under complex dynamic postural loads

Complex postural loads have a significant effect on all systems of the human body. Such movements in space create unique conditions for the correction of his hemodynamics. Special technical means are required to ensure reliable registration of physiological parameters. The aim of the work was the development of such a multi-channel device with high accuracy of analog to digital signal conversion and wireless data transmission. To develop the device, methods of automatic control and digital signal processing were used. Schemes of adaptive amplification of signals with automatic choice of a working point have been developed. The device is implemented on the basis of a modern electronic base using fast ADCs (1000 kbps), microcontrollers (32 bits) and Bluetooth modules (4th generation). The tests that confirmed the declared characteristics were carried out. Also, the developed device was used in a complex study of the neuro-systemic reactions of the human body to complex postural loads.
