Alarm system
First Claim
1. A reduced pressure therapy system comprising:
- a suction device comprising a suction chamber; and
a fluid retention system comprising;
an absorbent material having a non-hydrated state and a hydrated state; and
a carrier structure within the suction chamber, wherein the carrier structure comprises at least one wall forming a cavity, and wherein (i) when the absorbent material is in the non-hydrated state, the carrier structure is configured to retain the absorbent material within the cavity and (ii) when the absorbent material is in the hydrated state, the carrier structure is configured to release the absorbent material from within the cavity such that the absorbent material expands through the at least one wall and into the suction chamber.

Abstract
Described herein are alarm systems for suction devices for reduced pressure therapy. Alarms systems provide alerts to the patient and/or practitioner regarding the ability of the suction device to continue to provide negative pressure to a tissue region. Alarm systems comprise a sensor mechanism, which is capable of detecting the position of a slidable seal within the suction device, and generating an alert. Certain variations of alarms systems comprise magnetic field sensitive switches and/or electric switches. Other variations of alarm systems comprise rotary encoders to detect the motion and location of constant force springs, which signal the notification mechanism to issue alerts accordingly. Described herein are alarm devices configured to retain a suction device therein and to attach the suction device to a patient. The alarm devices disclosed herein detect the depleted state of the suction device and are capable of retaining the suction device in a plurality of orientations.
