Trauma patients with no uterinecontraction activity, usually do not have abruption, while patients with greater than one contraction per 10 minutes (6 per hour) have a 20% incidence of abruption.
The signals of fetal heart beating, uterinecontraction and mark were processed with the DSP TMS320LF2407A. Meanwhile, the volume control of the heart beat sound was realized by the DSP module.
Result: The results showed shortened labor duration, alleviated pain of uterinecontraction, and moderate volume of postpartum hemorrhage in experiment group.
