Peritoneal Dialysis (PD) is a therapeutic method that removes waste products and excess fluid from the blood, assisting the kidneys in maintaining organ function. This treatment is now available for pets, effectively extending their lifespan and enhancing their quality of life.
A sterile dialysate solution is introduced into the pet’s abdominal cavity through a surgically implanted catheter. As the dialysate dwells in the 腹腔,waste substances and excess electrolytes in the blood pass through the peritoneal membrane and mix with the dialysate. After a specified dwell time, the waste-laden fluid is drained from the abdomen via the catheter. Fresh dialysate is then infused, repeating the purification cycle.
This process is fully automated by an Automatic Peritoneal Dialysis (APD) machine, with its core component—the "circulator"—executing dialysate exchange with precision. SXEGL linear stepper motors drive the circulator and other critical components within the APD, ensuring safe and stable delivery of precise dialysate volumes into the pet’s abdominal cavity.
• Precision Control: Requires sub-millimeter positioning accuracy to match treatment protocols for dialysate dosage and exchange rate
• Reliability & Stability: Designed for 24/7 operation, motor performance directly impacts treatment safety and continuity
• Gentle Force Output: Strict torque control to prevent mechanical stress on the pet’s abdominal cavity during fluid transfer
• Ultra-Compact Form Factor: Fits within the limited internal space of portable or benchtop APD devices
• Flexible Integration: Standardized interfaces enable quick embedding into existing system architectures, reducing engineering effort
• Customizable Configurations: Tailored motor characteristics for optimized flow rate, pressure, and other parameters
• Broad Compatibility: Works with multiple 主流 drivers and control protocols for seamless integration with different APD brands

SXEGL linear stepper motor:
SXEGL linear stepper motors deliver direct linear force and motion through a core design combining a rotary motor (stepper, brushed DC, or brushless servo) with a lead screw integrated to a precision nut. As the motor rotor rotates, the screw-nut interface efficiently converts rotational motion into linear displacement—enabling functions like lifting, lowering, sliding, adjusting, tilting, pushing, or pulling objects with simple control inputs.
Performance metrics of linear stepper motors—including force output, speed, precision, and form factor—depend on multiple configurations, such as motor size, screw diameter, gearbox ratio (if equipped), and additional accessories like limit switches and position-sensing encoders.
SXEGL linear stepper motors offer distinct advantages in the following applications:
- Automatic Valve Control - Motor-driven precision actuation minimizes infection risks for animal patients by ensuring sterile, contactless valve operation
- Precision Fluid Management - Sub-millimeter positioning accuracy guarantees exact volume control during dialysate drainage, eliminating dosage errors
- Durable & Intelligent Design - Integrated multi-fault detection and alarm functions alert healthcare technicians immediately in case of system anomalies, ensuring 10,000+ hours of reliable operation
The veterinary medical market is experiencing rapid growth, with innovative solution providers developing next-generation healthcare technologies for pets.
