Datwyler and Roncadelle develop new safety syringe

Datwyler, a provider of system-critical elastomer components, has supported Roncadelle Operations in developing SafeR – a safety syringe with a needle retraction mechanism designed to eliminate needlestick injuries. 

After a single injection, the SafeR syringe automatically retracts the exposed needle, removing it from harm’s way, preventing the re-use of the syringe and promoting infection control. 

Erik Ryckalts, CEO Roncadelle Operations, said: “With the aim to provide next-level drug delivery for patients while creating a safer environment for healthcare providers, we are proud to launch the best-in-class retractable syringe – SafeR. This innovation is a result of intensive teamwork between Datwyler and Roncadelle Operations. We had a clear vision for the final product, and Datwyler contributed industry knowledge and a deep understanding of materials and medical device design to make it a reality within a very short timeline.”

For better healthcare practices, SafeR features a One-Touch needle retraction mechanism upon completion of the injection, as well as Auto Disable (AD), Re-Use Prevention (RUP), and Sharp Injury Protection (SIP) safety mechanisms in one device.

The combination of these safety features aims to protects patients, healthcare workers, waste management workers and the community from the risk of accidental needlestick injuries and syringe re-use.

With over 40 years of industry experience, Datwyler advised on the bespoke syringe design. Thanks to their unique shape with a hole in the centre, Datwyler‘s rubber plungers make a contribution to ensuring that safety mechanisms function perfectly and the needle is safely retracted after a single use. Datwyler’s extensive knowledge of the disposable syringe market ensured that key material and sealing options were considered for this patented application. 

The polyisoprene-based compound used for the plungers meets the most demanding application requirements. It is not only latex-free but also ensures consistent physical properties: the hardness of the material, the tensile strength and the compression set remain unchanged for the lifetime of the syringe.

Ryckalts added: “The Datwyler team provided comprehensive support throughout the development stage, going above and beyond the traditional component supplier role. They truly believe in our product and in creating a safer environment for healthcare workers. With an innovative supplier like Datwyler, we are confident that we can make the world a safer place one syringe at a time.”

Commercial production of SafeR will start in Italy in early 2022 with a CE mark pending and expected at the beginning of 2022.
