Skin-adhered design
The device attaches to the skin at the injection site and stays in place on its own.
Subcutaneous drug-delivery technology
Hands‑free injection technology, designed around people.
Developing innovative subcutaneous drug-delivery devices designed to simplify injection experiences and support pharmaceutical development opportunities.
Devices shown are development concepts and are not commercially available.
01The company
Medical-device engineering for hands‑free subcutaneous delivery.
We develop injection-device concepts that let a subcutaneous injection run on its own once started — so the person receiving it does not have to hold a device steady while the dose is delivered.
Technology focus
Skin-adhered devices with mechanical, automatic injection sequences.
Device concepts
A hands-free autoinjector and a wearable bolus injector (WBI).
Development approach
Engineering-led design that keeps usability in view from the first concept.
Collaboration
Open to working with pharmaceutical and medical-device partners.
02Technology
An injection that runs itself after activation.
The device concepts combine a skin-adhered design with a mechanical mechanism that carries out the injection automatically.
Automatic injection mechanism
Needle insertion, delivery and retraction run as one automatic sequence.
Hands‑free after activation
Once activated, the user does not need to hold or press the device.
Device usability
User interaction is kept to a small number of clear steps.
Mechanical engineering
Injection sequences driven by mechanical mechanisms.
Drug-delivery device development
Concepts developed with pharmaceutical integration in mind.
03Device platform
Two device concepts, one hands‑free principle.
Both concepts are in development. Neither is approved or commercially available.
Hands-Free Autoinjector
Device conceptA skin-adhered injection device concept designed to carry out the injection automatically once it has been activated — so the user does not need to hold the device in place while the dose is delivered.
- Design concept
- The device is applied to the skin, activated, and then completes its injection sequence on its own: needle insertion, drug delivery, completion feedback and needle retraction.
- Key features
- Skin-adhered device design
- Hands-free operation after activation
- Automatic injection sequence
- Needle insertion and retraction concept
Wearable Bolus Injector
Device conceptA wearable injection-device concept intended for subcutaneous drug delivery. The device is worn on the body during the injection, removing the need to hold an injector in position.
- Wearable design concept
- The wearable bolus injector (WBI) concept is designed to adhere to the skin and deliver a bolus dose subcutaneously through an automatic, mechanically driven sequence.
- Key features
- Wearable, skin-adhered form factor
- Subcutaneous bolus delivery concept
- Automatic injection sequence after activation
- Needle insertion and retraction concept
04Why hands-free?
The design motivation behind skin-adhered injection.
Hands-free injection devices are an area of active design work across the drug-delivery field. These are the considerations that shape our concepts.
Device handling
A handheld injector has to be positioned and held steady. A skin-adhered device stays in place on its own once applied.
Injection duration
Some subcutaneous injections take longer than a moment. Holding a device for that time can be demanding.
Dexterity considerations
Not everyone finds it easy to grip, press and hold a device. Reducing those demands is a core design goal.
User interaction
Fewer steps leave less to remember. The concepts aim for a short, clear sequence of user actions.
Skin-adhered concepts
Adhering the device to the skin is intended to make the injection less dependent on how steady the user’s hands are.
Potential usability benefits
Whether these design choices improve usability for a given therapy and user group has to be shown through usability engineering and evaluation.
05How it works
Seven stages, from packaging to disposal.
A conceptual walk-through of the hands-free injection sequence.
Step 01 / 07Schematic · not to scale
Device preparation
The device is taken from its packaging and prepared for use. The exact preparation steps depend on the final device configuration and primary container.
Step 02 / 07Schematic · not to scale
Application to the skin
The device is placed on the injection site and adheres to the skin, so it stays in position without being held.
Step 03 / 07Schematic · not to scale
Activation
The user starts the injection with a single activation step. From this point the device runs its sequence on its own.
Step 04 / 07Schematic · not to scale
Automatic injection
The mechanism inserts the needle and delivers the dose subcutaneously. The user’s hands are free while this takes place.
Step 05 / 07Schematic · not to scale
Completion feedback
The device indicates that the injection is complete. The form of feedback — visual, audible or tactile — is part of ongoing design work.
Step 06 / 07Schematic · not to scale
Needle retraction
At the end of the sequence, the needle retracts back into the device.
Step 07 / 07Schematic · not to scale
Removal and disposal
The device is removed from the skin and disposed of according to the instructions that will accompany the final product.
Conceptual overview. This sequence describes the device concept for information only. It is not a substitute for approved instructions for use, and the final steps may change as development progresses.
06Design features
What the concepts are designed to do.
Design features of the concepts — not claims about clinical outcomes. Compatibility with a specific drug product is assessed case by case.
Hands‑free operation
The injection continues without the user holding the device.
Skin-adhered device design
Attaches at the injection site for the duration of delivery.
Less need to hold steady
Adhesion takes over the job of keeping the device in position.
Automatic injection sequence
Insertion, delivery and retraction run automatically after activation.
Needle insertion and retraction
The needle is inserted automatically, then retracts at the end of the sequence.
Completion feedback
The device signals when the injection is complete.
Usability considerations
Designed around a short, clear set of user steps.
Mechanical actuation
The injection sequence is mechanically driven.
Primary packaging compatibility
Designed with standard pharmaceutical primary containers in mind; compatibility is assessed for each drug product.
