Abstract: Devices and methods for automatically maintaining disinfection of access sites of medical devices using ultraviolet light are disclosed. In one example approach, a device comprises a controller and an ultraviolet light source incorporated into a chamber of an enclosure which is closeable over access ports. In response to an adjustment of the enclosure from an open position to a closed position, the controller illuminates the ultraviolet light source for a predetermined first duration while the enclosure is maintained in the closed position. Following illumination of the ultraviolet light source for the first duration, the controller illuminates the ultraviolet light source for a predetermined second duration at predetermined time intervals while the enclosure is maintained in the closed position.

Abstract: A wearable thorax percussion device for dislodging mucous buildup in the airways of a human patient, the device comprising frame elements and electromechanical actuators retained by the frame elements to intermittently percuss the thorax, and an electronic controller and power source for generating and modulating an electrical signal to energize the actuator. The frame elements may be interconnected by a garment, or fasteners and elastic or adjustable strapping.

Abstract: A wearable thorax percussion device for dislodging mucous buildup in the airways of a human patient, the device comprising a garment fitting over the thorax, a rigid element attached to the external surface of the garment, an electromechanical actuator retained by the rigid element to intermittently percuss the thorax, and an electronic controller for generating and modulating an electrical signal to energize the actuator. The rigid element may be adjustably positioned on the garment to accommodate thoraxes of different dimensions. The actuator may be compressible between the rigid element and the thorax to better maintain contact with the thorax.
