Monica AN 24


The small, wearable Monica AN24 is central to Monica's innovative labour and delivery monitoring, home care and research solutions. The AN24 can be used with either of two accessories during L&D:

  • The Monica IF24 CTG Interface Device, which enables Monica AN24 to act as an alternative 'transducer' input to your installed L&D monitor.
  • The Monica VS series combined with Monica AN24 provides a stand-alone L&D monitor

Unique Technology

Uses abdominal ECG electrodes to monitor the fetal ECG, maternal ECG and uterine EMG1; and a powerful internal processor extracts in real time the FHR, MHR and UA waveform


  • Monitors the maternal and fetal ECG shape to confidently provide the fetal heart rate, even when fetal and maternal heart rates are similar
  • Uterine contractions are closer in accuracy to IUPC than TOCO
  • Improves uterine contraction detection without the risk associated with IUPC

Able to monitor obese women

  • Detection of abdominal fetal ECG and uterine EMG1 signals are minimally affected by BMI

Ambulation without transducer repositioning

  • Monica is a single set up device that requires no adjustment or repositioning no matter what the fetus or patient does
  • Midwives spend less time adjusting the equipment
  • Allows ambulation during Induction and labour to encourage delivery, reduce pain and interventions

Patient-friendly and convenient

  • No belts (meaning no pressure or belt irritation)
  • Freedom for natural birthing positions
  • Increase space around the bed for clinicians and birthing partners
  • Enhances the birthing experience
  • Offers a genuine alternative to the L&D room for post induction monitoring
