AI Technical Summary
The low flow rate design of the solenoid valve assembly in existing peritoneal dialysis machines leads to insufficient flow rate and prolonged exchange cycle. In particular, when the dialysate is of high viscosity or when the patient's intra-abdominal pressure fluctuates, it can easily lead to insufficient perfusion/drainage. Furthermore, the high frequency of opening and closing exacerbates component wear and energy consumption, affecting the reliability of the equipment.
A dedicated solenoid valve assembly for an integrated peritoneal dialysis machine was designed. By using a specially constructed manifold in conjunction with the T15 solenoid valve, the air port layout is optimized, significantly increasing the flow rate of a single valve passage, reducing the frequency of valve operation, and lowering mechanical wear and energy consumption.
It significantly improves the perfusion and emptying cycle of dialysis fluid, enhances the efficiency of metabolic waste removal, reduces fluid stagnation and abnormal reflux, and ensures the continuity and stability of the treatment process and the reliability of the equipment.
