MEASUREMENT SIGNAL TRANSMITTER FOR CONTINUOUS WATCHING OF THE MOTHER AND THE CHILD BEFORE AND DURING CHILD BIRTH.

摘要

in view of the ongoing monitoring of the mother and of the child before and during childbirth, a capsule (10) is placed on the bottom.the capsule contains a signal generator (20, 22, 32, 42, 54, 56) which provides more information on the state of the mother and the child, for example, the ecg.the work of labor, the temperature of the skin, the sound of the heart of the fetus.these data are converted to pulse repetition frequency is determined by the clock pulse via a multiplexer (64), and a pulse width modulator in (68).these pulses are transmitted to a receiver (57) from a transmitter (16) within the capsule (10), converted into analog signals and recorded by a recorder potentiometrique (58).the width of the pulses is limited by a time limit circuit (78 - 84), has a value which is smaller than the spacing time of clock pulses.the recorder potentiometrique (58) includes a capacitive divider (110) as the detector (mechanical balance of the deviation of the recorder.the separator is connected in such a manner that the work temperature and linear components connected after the fact are not critical.
