Medical device engineering and design is the initial stage in the production process of new instruments, appliances, and tools to be used in a broad array of surgical and medical processes. This design process does not only include implements and mechanisms that are used to treat patients at medical facilities and hospitals but also includes wearable, implantable, and portable devices that take up the role of human organs, closely monitor vitals of patients in real-time and deliver medication.

Just like any other engineering product in the market, the design process is vitally important as it dictates the functionality of the final product.

Aspects of medical device engineering

Aspects of medical device engineering are broadly classified into three categories, namely, software, electrical and mechanical. In most instances, medical devices do not require all three aspects. Most surgical devices such as retractors, scalpels, and clamps are entirely mechanical.

On the other hand, some incorporate both mechanical and electrical components but do not require any form of software to operate. Some of these devices include electric bone saws and blood pressure monitors.

However, due to the complexities of functions that need to be done by medical devices in the modern era, most do require electrical, mechanical, and software aspects to make it through the design process. 

The mechanical aspect, which is by far the most important in medical device engineering, must conform to several factors. One of the requirements is the strength of the device to withstand torque and tensional forces during operation. Strength influences choices such as bond types and the type of material to be used in construction.

Additionally, a material needs to check the biomechanical requirement, especially if the piece shall come into contact with the patient’s body. Finally, the expected lifetime of use is an important factor to consider. Generally, devices that are meant to be used for a couple of years are subjected to higher mechanical requirements as compared to single-use devices.


Medical device engineering is basically using principles in engineering and using them for healthcare benefits. If you have any idea on a device that could change people’s lives, feel free to contact BAAT medical to bring the idea to life.
