Results of Experiments with Fiber Pressure Sensor Applied in the Polish Artificial Heart Prosthesis

Abstract

The following paper introduces the problem of noninvasive pressure measurements in Polish artificial heart prosthesis. The pressure sensor is proposed and introduced, and preliminary tests are shown. The paper deals with the proposed sensing elements, requirement noninvasive solution and preliminary tests of polyurethane membrane transmission. The paper includes also experimental results of a fiber pressure sensor introducing noninvasive pressure measurements with pressure transmission through a polyurethane tube wall.

Noninvasive acoustic blood volume measurement system for the POLVAD prosthesis

“…A lot of work has been done in developing the pulsatile prosthesis POLVAD and its automation [2][3][4][5][6][7][8]. The Department of Optoelectronics at the Silesian University of Technology in Gliwice has been developing solutions for monitoring the POLVAD prosthesis for this program since the time it started [9][10][11][12][13][14]. The program is separated into three main stages on the way to its final solution (Fig.…”

Theoretical and model analysis of the unreliability of cardiac output measurement by means of the thermodilution method

“…It is monitored in the course of intensive therapy in order to check the progress and treatment of illness . Cardiac output is also estimated during mechanical heart supporting therapy [16,18,19,[22][23][24]. In other applications this parameter is used for numerical and physical modeling of the human circulatory system [17].…”

Preliminary Research Concerning Measurements οf the POLVAD Blood Chamber Volume Based οn Helmholtz's Acoustic Resonator Principle

“…Nowadays many efforts are taken with the purpose of effective solutions of problems concerning elaboration of the artificial heart [1][2][3][4][5][6][7][8][9][10]. It is caused by an alarming increase of the number of people suffering from heart diseases.…”

“…Recent research includes the real time blood volume measurement system for the POLVAD prosthesis. Previously the Department developed pressure measurement solutions for the prosthesis [5,6,10].…”
