Advanced Cardiotocography & Fetal Monitoring Training Simulator

The M191-1 SAKAMOTO Cardiotocograph Simulator 2 is a specialized obstetric and midwifery training simulator designed to provide practical training in fetal assessment, cardiotocography (CTG), fetal heart rate monitoring, abdominal assessment, and transducer placement.

Designed to represent a 39-week pregnant abdomen, the simulator allows nursing and midwifery students to practice the complete process of preparing and performing fetal monitoring in a realistic and controlled training environment.

The simulator combines a soft abdominal structure, a palpable fetal model, dedicated simulated Doppler and labor transducers, and an electronic control box that provides simulated fetal heart sounds and different fetal heart rate conditions.

Key Training Capabilities

1. Abdominal & Pregnancy Assessment

The simulator represents the abdomen of a woman at approximately 39 weeks of pregnancy, allowing learners to practice basic pregnancy-related measurements and assessment techniques.

Training includes:

• Abdominal circumference measurement
• Uterine fundal measurement
• Abdominal assessment
• Preparation for fetal monitoring

The realistic abdominal structure provides an appropriate platform for practicing clinical assessment before applying cardiotocography equipment.

2. Fetal Palpation

The abdominal section is designed with a soft structure that allows learners to palpate the fetus.

The included fetal palpation model incorporates anatomical features including a skull and pelvis, allowing learners to practice identifying fetal position and presentation.

Students can practice:

• Palpation of the uterine fundus
• Identification of fetal position
• Assessment of fetal presentation
• Palpation around the symphysis pubis
• Abdominal palpation techniques

Four Fetal Presentation Positions

The simulator supports training with four different fetal presentation positions, allowing instructors to expose learners to different clinical situations.

3. Doppler Transducer Placement

The simulator includes a simulation Doppler transducer and dedicated fixing belt for practical training in fetal heart monitoring.

Learners can practice:

• Correct positioning of the Doppler transducer
• Securing the transducer using the dedicated belt
• Locating the appropriate fetal heart sound area
• Checking whether the transducer has been positioned correctly

When the Doppler transducer is correctly positioned, the simulator’s control box provides the corresponding simulated fetal heartbeat.

If the transducer is incorrectly positioned, the simulated fetal heartbeat is not produced, providing immediate feedback during training.

4. Labor Transducer Placement

A dedicated simulation labor transducer and fixing belt are included.

Students can practice:

• Correct placement of the labor transducer
• Securing the transducer belt
• Checking the positioning of the transducer
• Understanding the relationship between transducer placement and monitoring

The system provides a visual indication when the labor transducer has been correctly secured.

5. Fetal Heart Rate Monitoring

The simulator provides simulated fetal heart sounds that can be detected through the dedicated monitoring system.

Fetal heart rate conditions can be selected to represent different clinical situations, including:

• Normal fetal heart rate: 120 BPM
• Tachycardia: >180 BPM
• Bradycardia: <110 BPM

This allows students to practice identifying abnormal fetal heart rate conditions and responding appropriately during simulated monitoring scenarios.

6. Four Fetal Heart Rate Patterns

The simulator supports training using four different simulated cardiotocography patterns:

• Normal
• Tachycardia
• Bradycardia
• Transient bradycardia

These scenarios help learners develop familiarity with different fetal heart rate patterns encountered during fetal monitoring.

7. CTG Recording Paper Training

The simulator includes four types of simulated recording paper corresponding to the available waveform patterns.

The recording paper is designed at the same size as actual recording paper and measures approximately:

15 × 60 cm

Learners can practice handling and interpreting simulated CTG recording patterns as part of the monitoring procedure.

8. Alarm & Placement Feedback

The simulator provides feedback based on transducer positioning.

When the alarm function is activated:

• Incorrect Doppler transducer placement can trigger an alarm.
• Correct placement allows the simulated fetal heartbeat to be heard.
• Correct labor transducer placement activates the corresponding indicator.

This provides learners with immediate feedback and reinforces correct equipment-placement techniques.

Clinical Skills Training

The M191-1 can be used to train a range of practical obstetric and midwifery skills, including:

Maternal Assessment

• Abdominal circumference measurement
• Fundal height measurement
• Abdominal palpation

Fetal Assessment

• Fetal position assessment
• Fetal presentation assessment
• Fetal palpation
• Identification of fetal heart sound location

Cardiotocography

• Doppler transducer placement
• Labor transducer placement
• Transducer fixation
• Fetal heart rate monitoring
• Recognition of normal and abnormal fetal heart rates
• CTG waveform training
• Alarm response and placement verification

Simulation Scenarios

The M191-1 allows educators to create practical learning scenarios involving different fetal conditions.

Students can be asked to:

1. Assess the pregnant abdomen.
2. Perform abdominal measurements.
3. Palpate and identify the fetal position.
4. Determine the appropriate location for fetal heart monitoring.
5. Position and secure the Doppler transducer.
6. Position and secure the labor transducer.
7. Listen to the simulated fetal heartbeat.
8. Identify the fetal heart rate condition.
9. Review the corresponding CTG waveform.
10. Recognize abnormal fetal heart rate patterns.

This workflow supports structured hands-on obstetric and midwifery training.

Immediate Feedback for Learners

The simulator provides practical feedback during transducer-placement training.

Correct positioning results in the expected simulated response, while incorrect positioning prevents the corresponding response or activates the alarm depending on the selected function.

This allows students to recognize and correct positioning errors during practice rather than simply observing a demonstration.
