In modern home healthcare, the prevalence of Peritoneal Dialysis Machines (Cyclers) has placed stringent demands on micro-power systems. Since these devices typically operate overnight, the Sound Pressure Level (SPL) and Long-term Operational Reliability of the drive system directly impact patient treatment quality.
The noise in dialysis pumps primarily stems from mechanical friction and electromagnetic vibration. Traditional brushed motors generate persistent friction noise and high-frequency EMI due to physical contact between brushes and commutators.
The BL2418 series eliminates the primary noise source through a brushless design. Combined with a precision-machined 2.0mm shaft and high-quality bearings, its operational noise is significantly lower than brushed counterparts, meeting the quiet environment requirements (typically below 45dB) for home medical use.
Portable dialysis equipment requires extremely compact internal layouts. Heat accumulation can shorten motor life and potentially affect the physical properties of medical fluids.
With an outer diameter of 24.4mm and a height of 18.0mm, the BL2418 provides ample space for precision gearboxes. Its high energy efficiency ensures minimal heat dissipation during continuous DC 12V/24V operation, maintaining device surface temperatures within medical safety standards.
Dialysis fluid infusion requires high volumetric accuracy. The BL2418 offers integrated electronic control features:
PWM Speed Control: Enables real-time adjustment of pump flow rates.
FG Signal Feedback: Allows the closed-loop system to monitor RPM. Any occlusion or pressure anomaly is detected via RPM fluctuations, triggering immediate safety alarms.
For medical device OEMs, the BL2418 is the ideal choice due to its maintenance-free longevity and wide voltage compatibility (DC 3V-24V). It transitions medical drives from simple rotation to intelligent, controllable, and silent motion solutions.
