Dialysis

Dialysis or renal replacement therapy is a blood purification process that removes toxic or waste substances from the blood of patients with chronic renal failure or chronic renal insufficiency. The exchange of substances here occurs by means of diffusion via a semipermeable dialysis membrane. Different dialysis methods are hemodialysis, hemofiltration and hemodiafiltration.

Modern dialysis devices use a variety of sensors for safety-critical monitoring of pressure, flow and liquid level in the dialysate and blood circulation as well as for detecting leaks and air in the hose system. In particular, the patient's blood pressure must be monitored continuously during dialysis.

Our sensor solutions for dialysis

First Sensor provides various sensor solutions for dialysis. Our highly accurate piezoresistive silicon pressure sensors of the HDI and HCE series with digital I²C or SPI interfaces are used for indirectly monitoring the blood pressure. Customized pressure measuring ranges in the overpressure and negative pressure (vacuum) area are available for these sensors. In addition, First Sensor develops and manufactures multi-sensor modules that integrate a variety of components such as sensors, valves, pumps, switches, and micro-controllers to create compact plug-and-play solutions. The use of plastic manifolds allows the precise three-dimensional arrangement of flow channels without the need for cumbersome and fault-prone piping for the individual components. First Sensor's manifold modules provide you with cost savings in the development of OEM devices along with competitive advantages thanks to short development cycles.

First Sensor also develops and manufactures customized front-flush pressure transmitters for dialysis devices based on highly precise piezoresistive ceramic or stainless steel pressure measuring cells with long-term stability. Our opto-electronic liquid level switches of the OLP and OLT series are suitable for detecting leaks in the dialysate and blood circulation or for liquid level measurement. A blood leakage through the dialysis membrane into the dialysate is detected by special optical sensors that measure the blood concentration and output a signal if a definite threshold value is exceeded. First Sensor's ultrasonic sensors detect air bubbles in various tube lines in a non-contact and hence sterile manner and consequently prevent the air from entering the patient's bloodstream.
