A UTERINE CONTRACTION MEASUREMENT DEVICE AND A FETAL MONITORING SYSTEM

摘要

A uterine contraction measurement device (2) having an elastic structure (6) with a contact surface to receive a tangential stress (F2) from a woman's abdomen (4) and a piezoelectric element (10) mechanically coupled to the elastic structure (6) such that the tangential stress (F2) from opposing directions of the piezoelectric element (10) are transferable from the elastic structure (6) to the piezoelectric element (10). The uterine contraction device (2) has a processor (14) to process the signal received from the piezoelectric element (10) and generate a uterine contraction data. A uterine contraction data (2) is further displayed on a display unit (16) which is also a part of the uterine contraction measurement device (2).
