Digi+ is a Paediatric Event Monitor System featuring a rechargeable Event Monitor, Disposable Digital Electrodes, and Alarm Charging Dock.  

The system is loaned out for up to 7 days to record irregular heart data. The child/parent must activate the event slider when the child experiences suspicious symptoms. Data is then stored for a medical professional to analyse on the products' return.  

Many medical devices in-use were designed for adults and scaled-down for children without much consideration for emotional response, cognition, and user behaviours. Since Cardiac data is influenced by the child's emotions, it aims to reduce frustration and anxiety but increase acceptance and satisfaction.  

Issues of existing devices include tangled leads, weak adhesive patches requiring reapplication, inaccurate reapplication, reduced patient mobility, large boxy forms, uncomfortable worn items.  

With physical symptoms related to heart conditions like swelling and breathing difficulties, the product avoids constricting the body, and the electrodes are made of a flexible silicone rubber. The lightweight electrodes conform to the skin. 

Digi+ improves patient mobility by removing leads and replacing the analog system, reducing the size, and adding a rotating flexible strap to allow for bending movements.   

The preassembled electrode features long-wear adhesive patches. The chain of electrodes requires less movement to apply as the rest of the chain hangs close by.  

The typical Event Button being replaced by a spring-loaded slider part, acts as a cover so electronics are not damaged by bumps on the outer surface.  

Inspired by different successful products such as CGM devices, neural electrodes, nurses watches, and research into new materials and technologies. These dry Capacitive electrodes use screen printed Carbon Nano Material capacitors which are more commonly used in Neural electrodes but have been proven to be suited for collecting cardiac data too.  

Suitability to medical situations meant adding large radii for easy cleaning, glossing off white surfaces, adding anti-bacterial anti-mould polymer additives, biocompatible materials, and more.
