Designing a User-Friendly Medical Device
Design and development of a medical device is the most crucial phase for its success. And the most important factor of the design is its usability. When Grandesign (part of the VANGEST Group) worked on the BTS project in collaboration with Biosystems, designing a user-friendly device was the main focus.
Designing the BTS Semi-Automatic Analyser
”Design is an art with a science to it. Usability is a science with an art to it. The two are inextricably linked. Defining usability is critical, and so is ensuring we are always solving for the right thing.”
We designed the interface for easy readability because accurate readings for medical devices are imperative. The device has a colour touch-screen, and the interface has large graphics for easy navigation and readability. We wanted to ensure an effortless user experience with easy to understand functions.
Validating the Design
In this case for the BTS project, we prototyped the device in our Rapid Prototyping and Manufacturing Centre in order to validate the design and functionality between the separate parts (a metal base support and plastic parts). In addition, we needed to see if our design was feasible for production and that it was structurally strong. We used our 3D printing facility to print out each part. Once the parts were verified, we made silicon moulds. After each part was made and the finishing process was completed, we assembled the device to produce a prototype.
Prototyping is an important step for the product development process, because we can see what is working and what adjustments we need to make before the medical device goes for mass production.
In the entire process when we were designing the BTS device, we always kept the user in mind. If the user can easily navigate the device, they can provide rapid and accurate results. These factors make the device reliable and enhance its overall performance. A good design is a user-friendly design.
