Brief
Alloy partnered with G+N to redesign the medical chest drain catheter securing process, with a focus on patient comfort, infection control, and clinical workflow efficiency. Clinical insights were translated into a system-level solution suitable for hospital use and procurement.
Outcome: A tender-ready medical device system combining an elastomer strap, silicone adhesive guide, and protective barrier film to securely stabilise chest drain catheters and reduce infection risk in clinical environments.
Key Outcomes
0
Reduction in infections
Design improvements targeting up to a 50 percent reduction in infection risk through improved catheter stabilisation and wound protection.0
Clinical trials conducted
Five clinical trials conducted to evaluate usability, comfort, and infection control performance of the chest drain catheter securing system.0
Key components
Three key components: an elastomer strap, a silicone adhesive guide, and a protective barrier film.
Creating the optimum catheter chest drain process
A very open brief, in a very specialized professional area. Alloy converted insights from observations and interviews with all the key expert stakeholders into detailed technical tender specifications. The project process included extensive specialist clinical briefings, wide ranging ideation, multiple iterative functional prototypes, DFM and materials research, final costing/tenda data. Overall the objective was to improve the efficiency, patient comfort and catheter protection during the chest drain process.
The solution:
Thin elastomer to secure the catheter is used along with a strap and adhesive silicone guide so optimum tube security and fixation is achieved. Clear Opsite material is quickly secured to the jig creating a barrier between wound and external hazards that could lead to infection. A visible, safe and secure chest drain is formed.
