Abstract
Methods and devices for treatment of damaged tissue are disclosed, including treatment of wounds by employing non-electrically powered, reduced pressure therapy devices. The devices are capable of generating a substantially constant reduced pressure with low tolerance for pressure fluctuations. Also disclosed herein are reduced pressure therapy systems that comprise an alarm system to detect the depleted state of the suction device and provide an alert to the patient and/or practitioner.
Claims20
A reduced pressure therapy system, comprising:
- a suction device comprising a suction chamber with an inlet opening and a slidable seal therein;
- a expandable fluid absorbent material located within the suction chamber;
- and
- a screen configured to block displacement of the expandable fluid absorbent material out of the suction device.
1 more element
A method of treating a patient, comprising:
- providing suction to a treatment site using a suction device;
- and
