Abstract: An applicator device allows for independent application of topical substances onto patients' skin, allowing self-application to difficult-to-reach areas. The applicator device includes a handle, an articulating segment, and an applicator head. The handle extends to a rotating joint between the handle and the articulating segment. A user activates the handle that operates to deliver the topical substance from an incorporation portion of the articulating segment to the applicator head and to the patient. The device meters the dispensed doses. The device can use disposable foam applicator pads and comes in a sleek, modern, ergonomic design. The device articulates and folds and rotates to provide easy access to previously hard-to-reach patient areas. The device can be easily stored, cleaned, and disinfected. The device prevents wasting of substances and solves the problem of overuse of topical medications, which can lead to adverse side effects.
