As a further development of the two component contraction recorder TOKOPORT, a digital microprocessor controlled contraction memory has been built which registers, analyses and displays contractions in pregnant women. The memorized data can be read out in graphic form. The possibility of conveying the data by telephone is under development. The device is small, simple to operate and portable.
