Usability evaluation of a compact pneumatic compression device for patients with lymphoedema

This is a usability study aiming to assess the fit, comfort and ease of use of a novel investigational pressure delivery system (referred to as Monterey), which will be used as the intervention in this study. The Monterey is an investigational system intended for patients with primary or secondary lymphoedema. It consists of the following components: • Pressure generator which delivers a pressure of 35 mmHG • Valve Interface • Patient interface: foot-thigh pneumatic compression garment • Connection tubes (Integrated Tube) The patient-interface is worn by wrapping it around the limb. It is then connected to the pressure generator via the provided tube. The valve interface is integrated into the patient-interface and its purpose is to allow segmented pressure control in the garment. Participants will be asked to visit the ResMed sleep centre, where they will be asked to use and provide feedback on the novel pressure delivery system. The study will involve two visits for participants and each visit will take up to 90mins. Visit 1 will assess the participants ability to connect the device and fit the pneumatic compression garment. Visit 2 will assess comfort when the device therapy is turned on (45 minutes for this study). As this is a usability study, there is no requirement on the frequency of visits. Visits will be scheduled based on participant availability. The entire study will be conducted under the supervision of the principal investigator. Usability and comfort will be assessed qualitatively using questionnaires.
