<p>PROBLEM TO BE SOLVED: To provide smaller scale, low cost bloodless and consecutive hemodynamometer with high reliability and precision by A/D converting a detected signal including biological parameters received by a bloodless sensor without passing through a filter means and a phase detecting means, and allowing a processor to calculate-execute filter processing and phase detecting processing. SOLUTION: In a hemodynamometer for measuring blood pressure in a bloodless and consecutive state, a detected signal including biological parameters received by a bloodless sensor 101 is digitized by an A/D converter 103, and a band pass filtering processing 104, a low pass filtering processing 105 and a phase detecting processing 106 are executed by a processor. Thus, it is not necessary to mount a filtering circuit and a phase detecting circuit, thereby a size is reduced. In addition, reliability and precision are improved by the reduction of analog circuits.</p> |
