The basis for the development of medical products according to IEC 62366 is the human-centred design process from DIN 9241, which has been an integral part of the development process at BUSSE for many years. For good usability, it is important that users can achieve their goals effectively, efficiently and satisfactorily while using a product. But user experience is often forgotten in the field of medical technology, which considers the areas before and after use. Application errors can be avoided by good design.

A medical device often has several different man-machine interfaces such as manipulation elements (control elements), display elements (e.g. displays) and sustentation elements (e.g. supports). These are operated by changing personnel with sometimes different tasks and objectives. They are intended to be sold and used internationally and are subject to strict legal requirements within the scope of approval.

Medical 720°

The BUSSE method for successful medical products

We look at the development of your products from both hardware and software perspectives. That's why we have taken the Human Centered Design Process further and literally go twice around a product in development: with the user-oriented view of a UI / UX designer and from the three-dimensional and functional view of the industrial designer and engineer. Thus, optimal operating and ergonomic concepts go hand in hand and not only well thought-out and operable products are created, but products that leave a positive, brand-forming experience through professional design. Thus, usability and optimal operability and process reliability are a central component. A normative requirement for medical products.

Usability in der Medizintechnik



Modern operating centre for eye surgery trimmed to a minimum footprint. A curved arm, which hovers above the patient, is mounted on a base geometric body with round corners and a high-gloss veneer. The treatment arm appears very slender and not very threatening due to atmospheric lighting effects and a play of penetrating attachments.

Der Mehrwert von Usability & UX

The added value of usability & UX and the link between design and development

Through human-centered product development according to the Human Centered Design Process, costs during development for design and development can be reduced. After the market launch, support teams and service are relieved through self-explanatory products. Users can work more productively, fewer errors occur and they are significantly more satisfied. The positive experience, the good "user experience" is always the focus of a development phase.
In addition, the early focus on the use cases allows operating and risk potentials to be identified and reduced - an important factor for successful market approval!

Trendreport 2020

MEDICAL Trends 2020

Inspired by our visit to MEDICA 2019, which is always held in November, and by our many projects from the medical technology sector and many other industries, we have also summarised what we consider to be the current design trends in the medical industry for 2020. We analyse these trends holistically in terms of product design, user interface, function and technology. In doing so, we place the user in the foreground.
