Medical devices need to operate around the clock reliably. Medical devices are not only life-improving but mainly life-sustaining. So it is important to reduce unexpected outages and avoid very expensive emergency visits of field service engineers.

Even from an experience with a customer delivering devices for smaller clinics to measure blood values or urine values, I can say that it is becoming more and more important that wearables measuring blood pressure are reliable and do not fail so that there is no demanding timeframe needed for their maintenance. The same applies for more complex devices even at a higher degree.

Predictive Maintenance is based on data generated and transmitted from medical devices whereby manufacturers can monitor the status of a medical device and recognise if it is operating normally or abnormally and proactively predict a possible failure and plan to intervene before the device breaks down. Sensors may record the environmental conditions such as the temperature of the medical device, the humidity, any kind of vibrations, etc.


Experience from a recent project

I have been involved in one project for more than a year focused on building up a big data, AI and service analytics platform. The data scientists are looking at all the data and exploring new AI-powered predictive models to predict future failures on device components associated with big cost impacts.


Optimising maintenance schedules

If you want to predict future outages, you need data. That is one of the reasons why many companies invest in the IoT, which creates data from various sensors. Imagine a smartphone. How many sensors does one have? It is amazing; such a small device has approximately 6–8 different sensors. With these sensors, data companies are building new applications.

If you consider a medical device, there are so many factors that can impact the functioning of a product. Sensors measure humidity, temperature in the operating area and so on. These all influence the time between maintenance events. In some countries, some elements fail quicker than others, and this need to be predicted and mitigated. The trick with predictive maintenance is to predict as precisely as possible when a system break will hit your customer; it should not predict the future event too far in advance nor in the reactive phase of handling.


Improvement of Customer Satisfaction

Automated data collection and processing makes it possible for a service provider to extract insights from the devices’ statuses, operations and behaviour. These insights unlock a tremendous potential: Manufacturers of medical devices can grow by refreshing their current product-related offerings by adding new digital services. According to a BCG study, companies that can successfully reposition their service capabilities stand to generate substantial standalone revenues with profit margins in the 35% to 40% range—more than 50% for best-in-class performers—while also improving customer satisfaction and providing a source of competitive differentiation.

    Recognising trends: An insight into regression analysis

    Data plays a very important role in every area of a company. When it comes to data, a distinction is made primarily between operational data and dispositive data. Operational data play an important role, especially in day-to-day business. However, they are not nearly as relevant as dispositive data. This is because these data are collected over a longer period of time and provide an initial insight into the history or the past.

    Why do we need digital transformation for medical devices?

    For hospitals, it is not up for discussion as to whether they want to digitalise. The increasing age of the population in western countries and the progressive shortage of medical professionals mean that without digitalisation, the healthcare system will not be able to provide the quality that patients want in the future.
