Dressing reduced-pressure indicators, systems, and methods

摘要

Dressings, systems, and methods are disclosed, in some embodiments, that involve treating a tissue site with reduced pressure, wherein the dressing includes a dressing reduced-pressure indicator that allows one to ascertain that the reduced pressure applied at the dressing is greater than a threshold reduced pressure. The dressing reduced-pressure indicator may include a moving member that is adapted to move under reduced pressure and a visual indicator associated with the moving member. Another embodiment uses an electro-mechanical indicator to provide a powered visual alert or audible alert or another output signal. Other dressings, systems, and methods are disclosed.

主权项

1. A reduced-pressure dressing for treating a tissue site on a patient with reduced pressure, the dressing comprising:
a dressing bolster for providing a reduced-pressure treatment space over a tissue site; a sealing member for covering the dressing bolster and a portion of the patient's epidermis; a reduced-pressure interface coupled to the sealing member for providing reduced pressure to the dressing bolster; a dressing reduced-pressure indicator fluidly coupled to the dressing bolster proximate the dressing bolster, wherein the dressing reduced-pressure indicator comprises:
a moving member that is adapted to move under reduced pressure, anda visual indicator associated with the moving member.
