Precision ventilation designed for clinical clarity and confidence.
The Hamilton HF90 was developed to deliver high-flow oxygen therapy in a compact, intuitive system tailored for modern clinical environments. RKS Design partnered with Hamilton Medical to translate complex respiratory technology into a clear, approachable user experience, balancing performance, ergonomics, and visual simplicity. Guided by Psycho-Aesthetics®, the HF90’s form, interface, and interaction design reduce cognitive load for clinicians while supporting accurate, efficient care delivery across acute and non-acute settings.

How We Used Psycho-Aesthetics™ to Identify Unique Opportunities in the Project.


Ethnographic Research
Key Outputs
- In-context observation of clinicians in respiratory care settings
- Workflow mapping across setup, use, and maintenance
- Identification of usability pain points and opportunity areas
- Behavioral insights informing ergonomic and interface decisions
Ethnographic research grounded the HF90 in real-world clinical environments, revealing how respiratory therapists and clinicians interact with high-flow therapy systems throughout a shift. Observations focused on setup, adjustment, cleaning, and mobility uncovered friction points and behavioral patterns that informed usability, ergonomics, and interface clarity, ensuring the HF90 integrates seamlessly into daily clinical practice.

Innovation Consulting
Key Outputs
- Opportunity framing aligned to clinical and market needs
- Feature prioritization informed by clinician insights
- Strategic alignment between engineering constraints and user value
- Differentiation strategy for high-flow therapy systems
RKS provided innovation consulting to align Hamilton Medical’s technical capabilities with unmet clinical needs and future-focused care models. Strategic guidance ensured the HF90 addressed not only functional performance requirements but also differentiation through usability, form factor, and system integration, supporting adoption across diverse care settings.





Prototyping
Key Outputs
- Multiple appearance model iterations exploring form, scale, and proportion
- Refinement of surface geometry and transitions for visual clarity
- Evaluation of component integration and overall product architecture
- Validation of clinical presence and approachability through physical models
Prototyping for the Hamilton HF90 centered on a series of appearance model iterations used to refine form, proportion, and visual clarity. These models allowed the team to evaluate how the device would be perceived in clinical environments, balancing approachability with precision and performance. Through iterative refinement, design decisions around scale, surface transitions, component integration, and overall presence were tested and evolved, ensuring the final design communicated confidence, cleanliness, and clinical reliability before advancing to production.





Industrial Design
Key Outputs
- Cohesive product architecture and form language
- Clinically appropriate material and finish strategy
- Compact footprint optimized for bedside and mobile use
- Clear integration of interface, hardware, and airflow components
Industrial design translated advanced respiratory technology into a compact, approachable, and clinically appropriate system. The HF90’s design balances cleanliness, durability, and visual clarity, reinforcing Hamilton Medical’s reputation for precision while ensuring the device feels intuitive and dependable in fast-paced healthcare environments.
