Automatic analyzer of embryonic heart beat

Abstract

Abstract PURPOSE: To reduce the load of the doctor for the pattern analyzing work, by measuring and recording the embryonic heart rate and the womb shrinking pressure of the pregnant woman and then comparing the specified variable constant calculated from these data with the fixed variable constant value for decision. CONSTITUTION: The heart rate signal and the womb shrinking pressure signal are supplied to the A/D converting part 4a from the heart rate detecting part 1 and the womb shrinking pressure dtecting part 2 each. Thus part 4a extracts these waveforms in the sampling cycle of, e.g., about 0.5 seconds. And these waveforms are then converted into the digital codes corresponding to the instantaneous waveheight value to be transferred to the data memory part 4b. The part 4b arranges and stores the digital codes corresponding to each waveheight value in the order of extraction and for the specified period of measurement, and then sends them to the temporary process parameter deciding part 4d 1 via the instantaneous process variable constant arithmetic process part 4c 1 and the periodical process variable constant arithmetic process part 4c 2 each to be compared with the fixed variable constant value. In this way, the load of the doctor can be reduced for the pattern analyzing work. COPYRIGHT: (C)1981,JPO&Japio
