CTG Machine Fetal Monitor Bistos BT350

Description

Bistos BT-350 – Advanced Specifications (Detailed)

DESCRIPTION:

• BT-350 LCD is an Antepartum Fetal monitor displaying FHR, UC, and FM on the LCD screen to check fetal health.
• BT-350 LED has the same functions as LCD type except having large 7-segment LED showing all the setting parameters and not having trend mode.
• It has also a event marker enabling a pregnant woman in the oed to indicate fetal movement point by pushing the button herself when she feels fetal movement.
• BT-350 indicates FHR as numeral by irradiating ultrasound at the abdomen, abstracting doppler frequency of heart rate cycle from the signals reflected from fetal heart, and outputting FHR change as s sound, and analyzing these signals. Bes des, you can measure UC oy using pressure sensor. BT-350 prints FHR, UC, and FM on the thermal paper and displays them on the LCD display.
• Especially, the doppler probe has 9 crystal sensers for catching FHR effectively, and it is water-proof type. BT-350 has 2 kinds of installation functions such as notebook, and wall mount.

1. Fetal Heart Rate (FHR) System

• Technology: Dual pulsed Doppler ultrasound
• Frequency: ≈ 0.985 MHz
• Intensity: ≤ 10 mW/cm² (safe for fetus)
• Range: 30 – 240 bpm
• Accuracy: ±2%
• Special:
  • Twin monitoring (FHR1 + FHR2)
  • Auto fetal movement detection (FM)

Better point: Dual Doppler + 9 crystal probe → strong signal pick (less error)

2. Uterine Contraction (UC / TOCO)

• Type: External TOCO probe (pressure sensor)
• Range: 0 – 99 / 0–100
• Feature:
  • Zero reference control
  • Real-time contraction graph

Labor monitoring reliable system

3. Display & Channels

• Screen: 7-inch TFT Color LCD
• Resolution: approx 800 × 480
• Channels:
  • FHR I
  • FHR II (twins)
  • UC
• Screen rotation: 180°
• LED version also available

Multi-channel simultaneous monitoring

4. Printing System (CTG Graph)

• Type: Thermal array printer
• Paper: 150 mm Z-fold
• Speed:
  • 1, 2, 3 cm/min
  • up to 10 cm/min (trend mode)
• Auto print:
  • 10–60 min interval

Continuous CTG trace for medico-legal record

5. Memory & Data Handling

• Patient storage: ≈150 patients
• Trend storage: ≈450 hours
