Pressure Sensor Solutions in Hemodialysis Equipment

Hemodialysis is a common treatment therapy, including in-center and home hemodialysis. Among them, the dialysis machine is a very important equipment. It consists of two parts: the blood monitoring alarm system and the dialysate supply system.

The blood monitoring alarm system includes a blood pump, a heparin pump, arteriovenous pressure monitoring and air monitoring, etc. The dialysate supply system includes temperature control, a liquid preparation system, a degassing system, a conductivity monitoring system, ultrafiltration monitoring and blood leakage monitoring, etc.

How does the Hemodialysis Work?

The dialysis concentrate and dialysis water are prepared into qualified dialysis fluid through the dialysis fluid supply system, and then pass through the hemodialyzer to undergo solute diffusion, osmosis, and ultrafiltration with the patient's blood drawn out from the blood monitoring alarm system. After the action, the patient's blood returns to the patient's body through the blood monitoring alarm system, and at the same time, the liquid used for dialysis is discharged from the dialysis fluid supply system as waste liquid. It is circulated back and forth continuously to complete the entire dialysis process.

Importance of Pressure Sensors in Hemodialysis Equipment

Accurate measurement of dialysate, arterial and venous pressure is essential for patient safety during dialysis treatment. when selecting pressure sensors for dialysis machines, it’s imperative to prioritize safety, precision, and material quality to ensure effective patient care and trust in the treatment process.

Pressure sensors need to accurately detect fluid and blood flow pressure to ensure that the pressure is maintained within the applicable range to avoid overpressure or underpressure, which affects the effectiveness of treatment. Because both overpressure and underpressure can cause blood vessel rupture or bubbles in the pipeline, which can be harmful to the patient's health. The materials used in these pressure sensors are essential, they must be biocompatible to ensure patient safety and prevent any adverse reactions. In addition, pressure sensors should provide a variety of installation and sealing methods to adapt to different application locations.
