This article introduces the components and functions of an computered analysis system for the women pelvic cavity impedance rheogram. It can sample the pelvic cavity impedance rheogram signal of the body double-side and the reference ECG signal. With help of manual intervence, it also can automatically recognize characteristic points of the pelvic cavity impedance rheogram and measure the parameters. It can correct the recognized characteristic points simultaneously and print the pelvic cavity impedance rheogram of the body double-side and 15 characteristic data parameters. After clinical applying, the analysis results of mors 100 patients make clear that: this system has remarkably clinical significance for diagnosis of the women pelvic cavity extravasated blood and evaluation of treating effect, so it has much better clinical applied expectation.
