Skin-adhered device design
The device attaches at the injection site and stays in position during delivery.
Technology
Hands‑free subcutaneous injection, engineered mechanically.
Our device concepts are applied to the skin, activated once, and then complete the injection automatically — from needle insertion to retraction.
01The principle
Activation is the last thing the user has to do.
With a conventional handheld injector, the user positions, presses and holds the device until delivery is finished. Our concepts move that work into the device: it adheres to the skin and runs the injection sequence itself.
- Skin-adhered device design
- Automatic injection sequence after a single activation
- Needle insertion and retraction handled by the mechanism
- Feedback when the injection is complete
02Technology areas
What the technology brings together.
Six areas define the platform across both device concepts.
Automatic injection mechanism
Insertion, delivery and retraction run as one sequence.
Hands‑free after activation
No holding, pressing or repositioning while the dose is delivered.
Device usability
Designed to keep user interaction simple and clear.
Mechanical engineering
Injection sequences driven by mechanical mechanisms.
Drug-delivery development
Developed with pharmaceutical integration and primary containers in mind.
03Technical features
Technical overview.
A structured view of the technology. Quantitative specifications are published once verified.
Mechanical actuation
The injection sequence is driven mechanically.
Automatic needle insertion
After activation, the mechanism inserts the needle into the subcutaneous tissue without further action from the user.
Needle retraction
At the end of delivery, the needle is withdrawn back into the device housing before the device is removed.
Injection feedback
The device indicates when the injection is complete, so the user knows when it can be removed.
Device configuration
How the mechanism, drug container and user interface are arranged within the skin-adhered housing.
Primary packaging compatibility
Designed with standard pharmaceutical primary packaging in mind, to ease integration with existing drug products. Compatibility is assessed for each drug product.
Cartridge and plunger interface
How the mechanism drives the plunger of the drug container is central to the design and to partner integration work.
Device usability
User steps are kept few and clear. Final usability will be established through formal usability engineering.
Engineering approach
Concepts move from principle to mechanism design, prototypes and feasibility work, with the user interaction defined in parallel.
