Image number: 10284314
This instrument, designed by Dr Lorand, recorded uterine contractions during labour and was strapped to the abdomen with an elastic belt. Contractions were mechanically transmitted to a pen recorder which marked the chart, while the drum revolved by means of a clockwork mechanism. The instrument shown here has a spare dial paper and elastic for the abdomen.
