Abstract: In an embodiment, an electrical stimulation system can include one or more of an electrode assembly including one or more electrodes and an electronics subsystem. In some variations, each of the one or more electrodes can include a hydrophilic layer and a conductive layer. In some variations, the electronics subsystem can include one or more of a control module, power module, and a stimulus generator. In some variations, the electrical stimulation can further include one or more of an electrical attachment system, mechanical attachment system, head apparel assembly, flexible housing, and/or any other suitable component. The electrical stimulation system functions to apply electrical stimulation but can additionally or alternatively function to measure/and or record one or more biosignals from a user.

Abstract: An apparatus is described that includes a vacuum line and a head coupled to a first end portion of the vacuum line. The vacuum line defines a fluid passageway. The head is configured to be removably coupled to a first portion of a reusable device. The head includes a contact portion configured to contact a surface associated with a target location. The contact portion is configured to circumscribe an opening to a bodily cavity associated with the target location. The head defines a volume through which a vacuum is conveyed to the surface associated with the target location. The volume is in fluid communication with the fluid passageway of the vacuum line.

Abstract: A container for sanitizing an article includes a case defining a central void sized to accommodate at least a portion of the article, a receptacle in fluid communication with the central void, and a granular, antiseptic media disposed within the receptacle. The granular, antiseptic media includes at least one out-gassing, antimicrobial agent such as, thyme oil or thymol. The granular, antiseptic media may further include a granular, fragrance blended with the granular, out-gassing, antimicrobial agent in a select ratio to remediate an antiseptic odor of the out-gassing, antimicrobial agent. The article may be a toothbrush or other type of brush, a mouth guard, a comb, a sponge, or other article which may be stored in a damp or wet condition after use.
