Abstract: In some embodiments, a medical system includes a dialysis machine having at least one outer surface to be disinfected at a given location, at least one disinfection sensor connected to the dialysis machine at the given location, the disinfection sensor including two or more electrode in fluid contact with the outside surface of the dialysis machine, and a conductivity sensor component in electrical contact with the two or more electrodes, the conductivity sensor component configured to send an electrical signal indicating a conductivity of a liquid on an outside surface of the dialysis machine and in contact with the two or more electrodes, a processor configured to receive the electrical signal and thereby determine a disinfection status of the given location, and a user interface configured to indicate the disinfection status of the given location.

Abstract: A container for containing an air freshener, comprising: (a) a first cup adapted to contain the air freshener, having a closed bottom and a first open top exposing the air freshener to the air; (b) a removable first seal covering the first open top to prevent loss of the air freshener prior to use; and (c) an attachment member on the closed bottom for connecting with a second cup to remove a second seal covering a second open top of the second cup. A method of using a first container to remove a cover on a second container, comprising: (a) contacting a bottom of the first container with a top of the second container; (b) rotating the first container relative to the second container, so that attachment means on the first container attaches to the cover of the second container; (c) removing the first container from the second container, thereby removing the cover from the second container.

Abstract: A multiple-purpose deodorant dispenser unit is provided, comprising: (a) first apparatus adapted for alternatively receiving (i) an aerosol spray deodorant container, (ii) an open deodorant container having gel, liquid or solid deodorant therein, or (iii) a wick cylinder having deodorant therein; (b) second apparatus adjacent to the first apparatus adapted for alternatively containing (i) a spray actuating head device for activating a nozzle in the aerosol spray deodorant container to emit a spray of vaporized deodorant, or (ii) a fan head device for directing a movement of air in the vicinity of either the open container or the wick cylinder; and (c) a third apparatus having electrical means for alternatively operating the spray actuating head device or the fan head device.

Abstract: A urinal cleaning unit for cleaning a urinal having periodic water flow therethrough comprises: (a) a mounting device for attaching the urinal clean unit to a urinal; (b) a disposable unit adapted for releasably attaching to the mounting device; and (c) a chamber in the disposable unit for containing a cleaning agent adapted to intercept a portion of the water flow. A method of cleaning a urinal having periodic water flow therethrough comprises: (a) mounting a disposable unit to a urinal; (b) enabling a portion of the water flow to flow through the disposable unit; and (c) mixing the portion of the water flow with a cleaning agent in the disposable unit to form a mixture of water and cleaning agent; and (d) releasing the mixture of water and cleaning agent to the urinal.
