leoni 4 ventilation premature infants clinic in operation

Reliable partnership and long-standing collaboration.

In an interview with Prof. (Ret.) Dr. med. Dominique Singer

Please briefly introduce yourself.

My name is Dominique Singer. I was head of the Neonatology and Pediatric Intensive Care Unit at the University Medical Center Hamburg-Eppendorf (UKE) from 2007 to 2025. Prior to that, I worked at the Children’s Hospital of the University Hospital Würzburg from 1999 to 2006, and before that in Göttingen.

I have a long-standing, trusting relationship with Löwenstein Medical – from joint workshops to the introduction of the LEONI at the UKE. To me, Löwenstein is a sound, dependable partner and an entrepreneurial life’s work that deserves the utmost respect.

Prof. (i. R.) Dr. med. Dominique Singer

Please explain to our readers which Löwenstein Medical products you work with and how long you’ve been working with them. 

I have a long history with Löwenstein Medical, formerly Heinen + Löwenstein. I still fondly remember the jointly organized workshops on thermal therapy at the GNPI conferences in Mainz, Cologne, Ulm, and Magdeburg (2002-2005). Later, our collaboration focused primarily on ventilation technology, particularly since the initial introduction of the “Leoni” ventilator in the neonatal intensive care unit at UKE. 

What do you particularly appreciate about Löwenstein products as a user? 

What impressed me from the very beginning was the active effort to meet the needs of users in clinical practice. Even during the development of the LEONI 4, I was shown a prototype one day, and I still clearly remember how my reactions to the more or less intuitive features of the display at the time were closely observed. 

What is especially important to you beyond the product itself? 

… Always having somebody you can call for even minor issues during daily use. At Löwenstein Medical, there has never been a “that can’t be” or “you’re the only one who’s had that problem.” Instead, observations from clinical practice have always been taken very seriously and addressed with thorough investigation. 

Were there any specific challenges in implementing the Löwenstein products at your hospital? 

The “interface issue” applies to Löwenstein products just as it does to those of all other manufacturers. In the networking of devices on an intensive care unit, there is still a gap between expectations and reality, largely due to the ongoing lack of standardization in the patient data management systems used by hospitals. 

What makes neonatology so special in the clinical setting, and why do you think Löwenstein’s solutions fit so well in this context? 

In the care of premature and newborn infants, it may not be true that “everything is different,” but many aspects do differ from the adult world, which is why specifically tailored solutions are of great benefit to both staff and patients. 

Would you recommend Löwenstein to other hospitals? 

Absolutely – for all the reasons mentioned above! 

Please complete the sentence, “My first thought when I hear Löwenstein Medical is ... 

a rock-solid partner who’s been reliable for many years – and a towering entrepreneurial achievement that commands my utmost respect on top of everything else!” 

Prof. Dr. med. Singer, thank you very much for the interview.
