The YpsoDose single-use injector is an electromechanical pre-filled and pre-assembled patch device for 10 mL glass cartridges. Needle insertion, injection, end of injection feedback and needle safety steps are all performed automatically. The needle remains hidden at all times and made safe after injection and device removal.

  • Unique sterile cartridge/fluid path and drive system provide safe and reproducible injections
  • Unique programmable electromechanical drive system for a range of viscosities and fill volumes
  • Programmable electronics to provide customisable patient feedback and connectivity
  • Customisable device housing shells to provide customer-specific device designs

Discover the ready-to-use, pre-assembled patch injector

Simplicity by design Patch and inject - as simple as that

YpsoDose is handled in a simple 2-step process: Patch and inject.

  • Ready to inject when attached and skin contact was automatically detected.
  • The device automatically sense skin contact and needle insertion and injection is initiated by the press of a button.

YpsoDose clearly communicates with the patient or caregiver via visual and audible signals before, during and after injection.


Simplified handling for the pharmaceutical industry Standard glass cartridges in a ready-to-fill format

YpsoDose works with a 10 mL glass cartridge that allows conventional bulk filling processes as well as filling in a ready-to-fill tub format. This allows the glass cartridge to be filled on a range of already existing filling equipment infrastructure. The fluid path is completed only at the actual time of injection.
