The Critical Need for Sensors in Dialysis
Dialysis machines perform a critical, life-sustaining function. These sophisticated machines require a variety of sensors and thermal management solutions in order to safely and accurately deliver fluids to the patient at the proper body temperature. In a hemodialysis machine, Figure 1 shows the variety of sensor and thermal management solutions required.
Regarding thermal management, heater assemblies warm the blood (or dialysate in the case of peritoneal dialysis) to body temperature. In order to design an effective, closed-loop-controlled heater assembly that is well integrated into the overall dialysis machine, a custom assembly is needed. The product designer would be well served to work closely with a supplier that has experience and capabilities to create the entire assembly. Not only does this save time and engineering resources, but some suppliers of these assemblies have sophisticated thermal modeling software that helps ensure the design will meet the specifications.
