Main Performance Specifications: Liquid Volume Accuracy: The maximum error for a single infusion should not exceed 30 mL or ±10% (whichever is greater). Heating System: Temperature control range: 34°C to 40°C; accuracy: ±1°C. Negative Pressure Drainage Assistance (Optional): Negative pressure range should not exceed 9.5 kPa. Alarm Sound: The sound pressure level during an alarm should be at least 60 dB(A-weighted). Operating Noise: The noise during operation should not exceed 55 dB(A-weighted). Liquid Height: During normal use, the recommended height difference between the dialysis fluid bag and the patient's abdomen, and between the patient's abdomen and the waste fluid bag, should be at least 40 cm. Liquid Flow Valve: The valve should open and close smoothly and reliably. When closed, there should be no liquid flow in the tubing. Weighing Device (Optional): The weighing range should be at least 0 kg to 10 kg, with a measurement error of ±20 g or ±2% of the nominal value (whichever is greater). Over-Infusion Protection: The machine should have a function to prevent excessive infusion of dialysis fluid. When the over-infusion limit is exceeded, the machine should emit an audible and visual alarm and stop the infusion.
Tube Blockage Protection: If the liquid tube is blocked during infusion, the machine should emit an audible and visual alarm and stop the infusion. Maximum Dialysis Cycles: ≥8 cycles. Maximum Dwell Time: ≥5 hours. Maximum Infusion Volume: 5000 mL per cycle. Minimum Infusion Volume: 20 mL per cycle. Infusion Volume Adjustment Increment: 1 mL. Maximum Drainage Volume Measurement: ≥20 L. Continuous Operation Capability: ≥48 hours.
