The hormonal treatment for in-vitro fertilisation (IVF) shall be handled in future with medical patches instead of injections. In order to achieve this pain-free form of medication, Pantec developed a manual device that creates tiny pores in the skin - a condition precedent for the therapeutic efficacy. A laser renders the skin permeable for the active ingredients on the patch. Along with IVF, Pantec has several large molecular active ingredients in the pipeline that have to be injected over extended periods of time. Zühlke was asked to develop the housing and plastic disposable units for this highly miniaturized system as well as a moving deflection unit for the laser (scanner). The scanner deflects the laser beam in five seconds, enabling up to 900 pores to be created in a defined pattern in the skin.
Zühlke engineers worked with the customer in reviews and FMEA’s to identify the biggest risks for mechanics, electronics and optics throughout the system and to determine how to proceed.
