The device makes the traditional approach of a nurse call button redundant, by deconstructing the device to one without a physical button at all – by providing a totally new method of activation, incorporating a flexible silicone air-bulb and an air-switch. This means that the resident can activate the pendant using their hand and fingers, and also their arm, or any other part of their body that can apply some force. The device is designed to be easily disassembled, allowing carers and nurses to thoroughly clean the device. The silicone bulb also means that the device is waterproof and floats, preventing it from being damaged through submersion. By making the silicone bulb transparent, the entire bulb acts as a light transmitting surface, with four bright colour-changing LEDs providing clear and recognisable light feedback patterns to reassure the user that the nurse call device has activated successfully. The pendant also provides passive light feedback, indicating that the device is electrically connected and functioning properly. Our co-design philosophy and research methodology that involved working closely with stakeholders and users was vital to the products success.
