Paving the way for future applications

Haselmeier aims to be a strong, proactive partner, driving meaningful healthcare innovations today and tomorrow. D-Flex heralds a new era in smart healthcare, opening multiple opportunities for pharmaceutical players and biotechnology companies, for example in drug development and clinical trials. The smart cap transforms D-Flex into an intelligent connected solution which enables biopharmaceutical partners to collect data at the point of care and improve the quality during clinical trials by monitoring compliance with study design during phases II and III. This makes a sustainable contribution to increasing and demonstrating therapy efficiency. D-Flex Connect also paves the way for greater patient engagement, facilitating personal health management via user-friendly apps.



Haselmeier's D-Flex Connect solution comprises the disposable D-Flex injection pen, a smart cap and innovative technology platform. Using integrated optical sensors in the pen, D-Flex Connect provides valuable feedback, not only confirming that the patient has taken the medication but also indicating the precise amount administered each time. This information on the time and dose of each subcutaneous application is automatically documented, giving a clear picture of the patient's current therapy status. Connectivity via smart phone app means patients receive a reminder if they forget to take a dose. Moreover, they can view details themselves, for example to check whether they have already administered the drug. This innovative combination of state-of-the-art disposable injection pen and future-proof connected platform provides peace of mind for patients and medical professionals alike and helps to enhance patient safety. What's more, clearer insights can help improve compliance and therapy effectiveness.

Saving time and cost

The flexibility of D-Flex Connect together with our pharmaceutical manufacturing and packaging services, and the possibilities for small-batch production mean this digital solution can support cost saving and time reduction in drug development.
