The requirements for a medical apparatus regarding its functionality, reliability and user-friendliness are ever-increasing. Accordingly, the development of a new blood pressure measurement system is a complex and multi-facetted task. This is why Finapres Medical Systems contracted DEMCON for the development of a new blood pressure measurement device. DEMCON has broad experience with the development of medical systems. DEMCON combines all technical disciplines under one roof, including system engineering, mechanical and electronic engineering, software development and industrial design. In addition, DEMCON has the required know-how regarding the international medical instrumentation guide lines and is experienced in the product certification process.
During the development of the new blood pressure measurement system, the Finapres NOVA, next to its user-friendliness the emphasis was placed on a modular implementation of a wide variety of functions. This is why the Finapres NOVA was developed as a measurement platform. For this platform, a variety of hardware modules and software applications are offered. On the hardware side the ECG, the oxygen saturation, the upper-arm calibration, and the analog input/output modules are already available. The available software applications include the ANS module for analyzing the autonomic nervous system, the hemodynamic module, that provides a large range of hemodynamic parameters such as the Cardiac Output, and a software module for optimizing the performance of pacemakers based on the blood pressure signature. The Finapres NOVA customer is thus in a position to configure a blood pressure measurement system tailored to his or her needs.
The blood pressure measurement systems of Finapres make use of a finger cuff. This cuff integrates two systems, a pressure system and a sensor system. The sensor system registers variations in the diameter of the finger artery. These variations are counter-acted by the pressure system of the cuff. This requires that the air pressure in the cuff can be increased or reduced rapidly, within milliseconds. The blood pressure is calculated from the air pressure in the cuff. By using a finger cuff, it is possible to monitor the blood pressure continuously for extended periods of time in a patient-friendly manner.
The excellent cooperation of both parties and the ambitions of DEMCON lead to Finapres joining the DEMCON group as an independent company. The research and development and the sales and marketing departments of Finapres work closely together with DEMCON on the development of the next generation of blood pressure measurement systems.
