Abstract:
1. A reduced pressure therapy system comprising: a suction device comprising a suction-generating chamber and a slidable seal therein, wherein the suction device has a minimum chamber size configuration and a maximum chamber size configuration; a magnet coupled to the slidable seal; and a separate portable alarm device configured to releasably retain the suction device in reversed predetermined orientations, wherein the portable alarm device comprises first and second sensors, embedded in set locations within a wall of the alarm device, configured to detect whether the suction device is in the maximum chamber size configuration, whereby each sensor is configured to detect the maximum chamber size configuration of the same suction device in reversed fixed orientations, whereby the alarm device is configured to detect that the suction device is in the maximum chamber size configuration by sensing the location of the magnet coupled to the slidable seal, and a notification mechanism configured to generate an alert indicating the detection of the maximum chamber size configuration.
