MANUALLY-ACTUATED REDUCED PRESSURE TREATMENT SYSTEM WITH AUDIBLE LEAK INDICATOR

摘要

Illustrative embodiments of new and useful systems and methods for reduced-pressure therapy are described. One example embodiment is a manually-actuated pump for applying reduced-pressure therapy. The pump generally comprises a charging chamber, a regulated chamber, and a regulator passage between the charging chamber and the regulated chamber. A valve body controls fluid communication through the regulator passage, and a regulator spring may be engaged with the valve body to bias the valve body against a differential between a pressure in the regulated chamber and an ambient pressure. The regulator passage may have a bore size adapted deflect the valve body to cause an audible indication of a leak.

1. A manually-actuated pump for applying reduced-pressure therapy, comprising:
a charging chamber; a regulated chamber; a regulator passage between the charging chamber and the regulated chamber; a valve body adapted to control fluid communication through the regulator passage; a regulator spring engaged with the valve body to bias the valve body against a differential between a pressure in the regulated chamber and an ambient pressure; and an outlet port coupled to the regulated chamber; wherein the regulator passage has a bore size adapted to deflect the valve body to cause an audible indication of a leak that exceeds a predetermined threshold.
