Introduction and aims

Ventilated patients in ITU (intensive treatment unit) tend to be challenging to communicate with, especially patients who are being weaned. These patients usually have tracheostomy in situ and use means such as writing or letter boards to communicate. The situation becomes complex in patient groups that have burn injuries with bulky dressings and restricted upper limb function. We demonstrate a low cost, easy to use, potentially disposable system that can display words on any television screen via patient input device for such patient groups.

Materials and methods

The system consists of input device incorporated with Arduino microcontroller (an open-source electronics prototyping platform based on easy-to-use hardware and software intended for creating interactive environments) and 4 generously oversized control buttons. These are used to control the cursor movements (up, down, left, right) while a fifth has a "select" function. These are large enough to be pressed by an entire bandaged hand using gross upper limb movements only. A standard television is used to display menu containing the 26 letters of the alphabet and a flashing cursor. The patient selects the required letters/icon by moving the cursor and the words so created are displayed along the lower part of the screen for the carers to read. It is envisaged that anyone with basic craft skills should be able to construct this device.

Conclusion

This device is a self-contained, cost-effective, simple, and open-source system that can be used effectively to bridge the communication gap with significant potential for patient care globally.
