Maestros CTG Machine-150 Mini Portable Fetal Monitor: Features, Uses & Buying Guide in Nepal

The Maestros CTG Machine-150 Mini Portable Fetal Monitor is a portable cardiotocography device designed for monitoring fetal heart rate and uterine activity during antenatal assessment and labor. CTG, or cardiotocography, provides healthcare professionals with information about the fetal heart rate and uterine contractions, helping them observe fetal and maternal activity during appropriate clinical monitoring. The CTG 150 Mini uses 1 MHz pulsed Doppler technology with autocorrelation for fetal heart rate measurement and a strain-gauge sensor for uterine activity monitoring. Its compact construction and rechargeable battery make it practical for maternity and obstetric environments where portability can be useful.
The CTG 150 Mini features a 7-inch color TFT touchscreen with 800 × 480 resolution, allowing clinicians to view monitoring information and traces on the display. It incorporates a high-resolution thermal printer with selectable chart speeds of 1, 2, and 3 cm per minute and uses 112 mm thermo-sensitive Z-fold paper. The device can store more than 24 hours of patient data and supports up to 99 patients according to the published specifications. Its built-in rechargeable 11.1V, 4400mAh lithium-ion battery provides more than three hours of operating time, while the AC power supply supports 100–240V input.
For healthcare facilities considering a Maestros CTG Machine-150 Mini Portable Fetal Monitor in Nepal, important factors include the monitoring parameters, display, fetal heart rate measurement range, uterine activity monitoring, printing capability, memory, battery backup, portability, accessories, and available technical support. The Mini model weighs approximately 2.5 kg and measures approximately 326 × 224 × 130 mm, making it considerably easier to move between suitable clinical areas than larger stationary monitoring systems. Optional features include twin fetal monitoring, SpO₂ and NIBP upgrades, central nursing-station connectivity, and real-time mobile data access, depending on the configuration supplied.

What Is the Maestros CTG Machine-150 Mini?
The Maestros CTG 150 Mini is a portable fetal monitor designed for cardiotocography. It monitors fetal heart rate and uterine activity using a fetal heart rate probe and TOCO probe. The device is intended for professional healthcare environments such as maternity hospitals, labor rooms, obstetric departments, and gynecology clinics.
Its portable design combines monitoring, data storage, and thermal printing in one compact unit. This allows healthcare professionals to review fetal monitoring information on the display and produce a physical CTG record when required.

What Does a CTG Machine Monitor?
A CTG machine primarily records fetal heart rate (FHR) and uterine activity (TOCO). The fetal heart rate probe uses pulsed Doppler technology to detect fetal heart activity, while the TOCO sensor measures uterine activity through an external strain-gauge sensor.
The Maestros CTG 150 Mini specifies an FHR measurement range of 50–210 BPM / 30–240 BPM, depending on the selected configuration or measurement range, with 1 BPM resolution. Its uterine activity measurement range is 0–100 units.
CTG recordings should be interpreted by appropriately trained healthcare professionals. The device provides monitoring information but does not replace clinical assessment or professional judgment.
Key Features of Maestros CTG 150 Mini
The 7-inch color TFT touchscreen provides a clear interface for viewing monitoring information, with an 800 × 480 display resolution. The touchscreen design allows healthcare professionals to interact with the device while monitoring fetal and uterine activity.
The fetal heart rate system uses 1 MHz pulsed Doppler with autocorrelation, with a resolution of 1 BPM. The device also uses a strain-gauge sensor for uterine activity and provides an FHR chart width of 8 cm and TOCO chart width of 4 cm.
The built-in high-resolution thermal printer supports chart speeds of 1, 2, and 3 cm per minute and uses 112 mm Z-fold or thermo-sensitive paper. This allows monitoring records to be printed for clinical documentation and review.
Another useful feature is its patient data storage capacity of more than 24 hours, with storage for up to 99 patients according to the published Mini specifications. This can be useful in clinical environments where monitoring records need to be retained within the device before review or printing.
The rechargeable 11.1V, 4400mAh lithium-ion battery provides more than three hours of operating time. Combined with the approximately 2.5 kg portable construction, this allows the CTG 150 Mini to be moved between appropriate clinical areas without depending solely on mains power.
Common Uses of CTG Machine-150 Mini
The Maestros CTG 150 Mini can be used in maternity hospitals, labor rooms, obstetric and gynecology clinics, nursing homes, and other suitable healthcare facilities for fetal and uterine monitoring. It may be used during antenatal assessment and labor monitoring when CTG is clinically indicated.
Because CTG is a clinical monitoring technique, the timing and duration of monitoring should be determined by qualified healthcare professionals based on the pregnancy and clinical situation.
Benefits of a Portable CTG Machine
Portability is one of the practical advantages of the CTG 150 Mini. At approximately 2.5 kg, the unit can be transported between suitable monitoring areas more easily than larger systems. Its rechargeable battery provides more than three hours of operating time, allowing monitoring to continue when mains power is temporarily unavailable.
The combination of a display, thermal printer, patient memory, fetal heart rate monitoring, and uterine activity monitoring in a single unit can also simplify routine CTG documentation. Optional configurations can provide additional monitoring or connectivity functions depending on the requirements of the healthcare facility.
