    Abstract: A universal adapter includes: a casing combinable with a front cover and a rear cover having a pair of outlet sockets formed in the rear cover to output power, a first plug having a pair of rectangular-shaped pins slidably held in an upper chamber in the casing and operatively pushed or pulled by a pair of first seesaw buttons pivotally secured on two opposite sides of the first plug for a convenient extending or retraction of the first plug, whereby upon extending of the first plug, a rectangular-shaped pin of "grounding pin" will be simultaneously biased for its forward extending to form triple rectangular-shaped pins for connecting municipal power such as in England or Africa to be output through the pair of outlet sockets in the rear cover; a second plug having a pair of flat blades slidably held in a lower chamber in the casing and operatively pushed or pulled by a pair of second seesaw buttons for a convenient extension or retraction for connecting municipal power to the two outlet sockets; and a third plug having a pair of round pins pivotally mounted on the front cover to be horizontally extended for power connection use and vertically received into the front cover when not in use.

    Abstract: The present innovation is a customized compression device for prevention and treatment of keloids and hypertrophic scarring, primarily a frequent complication of ear piercing. The “one size fits all” design of traditional devices can compromise efficacy due to uneven fit and compression. This invention harnesses 3D digital scanning to capture the intricate contours of the ear for every patient, for personalized compression therapy. Using 3D printing, shells are fabricated with biocompatible materials such as Polylactic Acid, shape memory polymers, or silicone-based substances. In primary embodiments, device functionality is achieved with compression clips or spring-open, single-piece structures. The custom fit, potential for infusion of therapeutic agents (e.g., corticosteroids), and engineered porosity combine to improve keloid management from uniform pressure distribution and optimal healing. Additionally, the ‘shells’ can be pigmented to match patient skin tones and encourage compliance. The invention thus offers tailored keloid treatment, as well as prevention for high-risk individuals.
