TOITU DOPPLER MT-332

MT-332

SINGLE FETUS INTRAPARTUM ACTOCARDIOGRAPH

Versatile, reliable, and durable, the MT-332 allows for comprehensive assessment of single fetus well-being when all the features of the  Actocardiography are used.  In addition to the detection and recording of Fetal Heart Rate (FHR) and Uterine Contractions (UC), pulsed ultrasound doppler signals automatically detect Fetal Movement (FM).  The FM is automatically recorded as an event dot or in spike waveform depending on the clinician's preference.  Maternal perception of FM can also be recorded using the event marker.

Compact, lightweight and portable, the MT-332 is conducive to all clinical settings, from physician's offices to Labor and Delivery suites.  It can be adapted to each patient situation, providing antepartum NSTs as well as FECG and intrauterine pressure measurements.
