The continuous and long-term use entails special requirements and safety precautions. The compressors are replaced every 10 years as part of the maintenance schedule of the Ikus drive unit. This is done purely as a preventive measure to exclude any possible hazard to the patient due to a potential failure of aging components. A long service life was not the only criteria that KNF diaphragm pumps had to meet.
Successful implementation of customer-specific requirements thanks to the KNF modular system
The high demands on the application were accompanied by clear specifications for the development of suitable, reliable diaphragm pumps. As a result, Berlin Heart provided clear specifications for the implementation of the EXCOR® diaphragm pumps: The pumps were to be efficient and low-maintenance, and the KNF diaphragm vacuum pumps provide all of this. They also impressed the developers at Berlin Heart with their quiet and low-vibration performance during operation. Using the KNF modular system, Berlin Heart and the KNF development team worked together to optimize the parameters until the N 023.1.2 series model was ideally adapted to meet customer’s specific requirements. Among other things, specially adapted ribbed plates and a special silicon wiring had to be used.
However, not only the manufacturer, but also the TÜV and international certification bodies require that the strictest standards must be met. By carefully fine-tuning all components to work with each other, Berlin Heart was able to obtain premarket approval (PMA) for its EXCOR® Pediatric product for the US market.
Successful use saves thousands of lives
The result is also convincing in practice: KNF pumps work reliably and quietly around the clock. The ventricular assist device from Berlin Heart supports around 180 children every year and has already saved more than 2,500 lives.
