The benefits of wave springs for medical applications

04 January 2021

There are more than 500,000 medical technologies on the market, from thermometers to mechanical ventilators.

Products typically have a short lifecycle of around 18 to 24 months before an improved version becomes available; design engineers in this sector are constantly innovating to improve patient care. Here, Simon Ward, Technical Manager at fastening and fixing supplier TFC, explains how designers can reduce the size of their devices with wave springs.

One example of rapid innovation is wearable technologies, which are now available to track everything from patient blood pressure to walking gait, electrolyte levels and heart rhythms. Across the board, we are seeing innovation in tools and technology for the prevention, diagnosis and management of diseases. As the use of digital technology in medical applications rises, engineers are designing new, innovative products to aid patient welfare.

When innovation makes technology more complex, design engineers are often challenged with device size, particularly when integrating all the mechanical components into a practical size. For example, traditional coil springs may be too large for medical technologies that are designed to be small and lightweight – causing the design engineer to consider alternatives.
