Abstract

Introduction: Compression therapy for keloid is an important adjuvant treatment of this pathological scar, especially to reduce its elevation, improve scar features (e.g. pliability and plasticity) and ease symptoms. However, this therapy is unpleasant and uncomfortable for patients, due to the need to combine elastic bands or garments, foams (Ethylene Vinyl Acetate) and silicone sheets, for at least 8 to 12 hours a day. Objective: To create a device to apply compression on keloid, which would facilitate and simplify the scar compression therapy. Material and Methods: A review of existing devices was carried out through the main databases of patents, as well as on common research platforms (desk research). Design Thinking was used for the elaboration of the prototypes to validate the concepts and the functionality of the device. The component parts were 3D printed and assembled to form a single device. Results: Eleven documents were found in the main search and none found in desk research. The device for keloid compression was developed using a spring mechanism, comprised by three structural units, which were attached as a single piece and it was adhesive to the skin. Conclusion: A device for keloid pressure therapy was developed using the Design Thinking.
