Controlled negative pressure apparatus and alarm mechanism

摘要

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. --------- 6 00 0 00 1000 1200 1400 1600 1800 2000 FIG. 24A 2404 -~ ---------- - FIG. 24B FIG. 24C
