The invention relates to a device for recording tokograms using a Inflatable balloons to be inserted rectally to capture the occurrence of the contraction of the uterus the pressure fluctuations, with a display device for the pressure fluctuations and with a Balloon inflator is connected.

In previously known devices for recording tokograms z. B. strain gauges 30 Including pressure transducer attached to the abdominal wall of the tearing end, with the contraction of the uterus occurring pressure fluctuations are transferred to the strain gauges and there are converted into electrical signals. Such an arrangement of pressure consumers On the one hand, the abdominal wall of the tearing end considerably impairs the freedom of movement of the tearing end on the other hand, there is the danger that, through violent movements of the tearing person, either the Pressure sensor completely torn off or its coupling to the abdominal wall disturbed at least so far it becomes that a perfect measurement is no longer possible

By the German utility model 1 701 717 a measuring device is also previously known, which contractions the female vagina or the pelvic muscle by means of a to be inserted into the vagina Captured pressure balloons. In principle, this measuring device can also be used to record tokograms use when the device's pressure balloon is inserted rectally up to the level of the uterus. By reducing the fluctuations in pressure that occur during contraction of the uterus by means of of a pressure balloon to be inserted rectally, the woman is no longer hindered in her freedom of movement. For anatomical and physiological reasons, there is also good contact between the customer and the the uterus guaranteed, with the coupling even with violent external influences on the Tearing end or with own movements of the mother remains relatively constant.
