Unlocking new efficiencies in Medical IoT

With digital transformation opening a world of possibilities in medicine, the internet of things (IoT) is making a wave of improvements by connecting devices that can benefit both healthcare providers and patients. The market is still gaining momentum, with healthcare IoT predicted to triple by 2022, giving medical engineers huge opportunities for innovative wireless connected technologies and further investment for their implementation to provide precise, result-orientated healthcare, manage any bottlenecks in care, bridge a gap between providers and patients and reduce overall costs.

Medical devices can collect additional invaluable data, more insight into symptoms and trends and give patients more control over treatments and remote care. Healthcare device manufacturers are now looking to IoT devices to for more precise, results-orientated healthcare, serving more patients, reducing overall hospital visits and improving costs.

With new efficiencies and benefits come new design challenges. Below are the top three challenges for Medical IoT applications to keep in mind:

These are our suggestions for the best technologies and solutions to keep in mind when designing Medical IoT applications:

Sensor Solutions

At the start of any IoT journey is data generation, whether that’s collecting data from multiple points and consolidating into one central hub, or sharing data from one point with multiple users. The decreasing cost of sensor technologies has encouraged healthcare manufacturers to build smarter, more efficient, economical products.

Perfectly complementing our IoT offer is a comprehensive range of specialist industrial-grade sensors. Capable of measuring almost any physical parameter, our miniature and low-power sensors allow for multiple and combined parameters to be measured and shared with the cloud within one compact component, so you can measure almost anything from almost anywhere. With these sensors you can be sure the data measured is of high quality, accurate and reliable.

Managed IoT Service/Cloud Software

For medical applications, monitoring needs to be 24/7. The collection of huge amounts of data from constant monitoring creates a challenge with managing, storing, transmitting and analysing a huge amount of data. This requires a platform to be reliable and accurate, so as not to cause a mis-diagnosis of a patient due to any loss of data with sufficient power so that its not subject to any failure. With this also comes the risk of a network being vulnerable to attack - problematic when dealing with confidential patient data and traditional network security and encryption technology will not be secure enough for medical applications.

Microbial Cabling

Medical IoT Cleanliness, quality and compliance are of great importance in the medical industry, our sister company, Contour Electronics with their industry experience of medical grade cable assemblies and clean room manufacturing is paving the way.

Their microbial cables have been incorporating SteriTouch® masterbatch into their assemblies for several years and are based on ionic silver as organisms find it difficult to develop resistance this material, making it a useful tool in areas where resistance to organic biocides may be a problem such as operating theatres and clean rooms. The SteriTouch® masterbatch added at the extrusion process has no adverse effect on the performance of the base material and will remain effective for the life of the product. Assemblies are manufactured and tested in a clean room with ISO14644 Class 7 standard to protect and ensure that bio-burden is not introduced by the manufacturing process, and supplied in medical device contract packaging.

An innovative and reliable manufacturer of cable assemblies, flexible circuits and full box build electronics with ISO 13485 accreditation, specialising in the design and manufacture of over-moulded cable assemblies using bio-compatible materials, sterilizable by autoclave, EO or irradiation.
