A system and method for performing tissue therapy may include applying a reduced pressure to a tissue site of a patient. A fluid parameter associated with applying a reduced pressure to the tissue site may be sensed. An audible fluid leak location sound may be generated in response to sensing the fluid parameter. The audible fluid leak location sound may be altered in response to sensing that the fluid parameter changes. By altering the audible fluid leak location sound in response to sensing a change of the fluid parameter, a clinician may detect location of a fluid leak at the drape by applying force to the drape. The force applied to the drape may be a clinician pressing a finger onto an edge of the drape.

Apparatus and method for locating fluid leaks in a reduced pressure dressing utilizing a remote device

In one example embodiment, a vibration apparatus can augment and enhance negative-pressure therapy systems. The apparatus can be attached to an external surface of a dressing, fluid conductor, or other components. The apparatus can generate low-amplitude vibrations, which can be transmitted through the components. Kinetic energy of the oscillations can agitate fluid in the components, which can lower the viscosity of the fluid and reduce the frequency of blockages in fluid conductors. Vibrations may also agitate a tissue site, which can encourage blood flow and granulation.

Fluid management apparatus and method

A pressure switch for controlling application of negative pressure to dressing disposed adjacent a tissue site is disclosed. The pressure switch comprises a body having a base, sidewalls extending from the base to an open end, and an inlet coupled to the dressing and forming a passage through the body. The pressure switch further comprises a diaphragm closing the open end of the sidewalls and forming a vacuum chamber with the body, wherein the inlet fluidly couples the vacuum chamber and the dressing. The pressure switch further comprises a valve disposed in the passage and configured to restrict the flow of gas through the passage so that a switch pressure developed in the vacuum chamber as a result of the application of negative pressure to the dressing lags a wound pressure at the tissue site to delay, wherein the diaphragm is adapted to be operatively responsive to the switch pressure to move between a relaxed position and a compressed position as the negative pressure increases and decreases. This pressure switch further comprises a switching element coupled to the diaphragm to turn on the negative pressure in the relaxed position and turn off the negative pressure in the compressed position. In another example, a method for controlling application of negative pressure to dressing disposed adjacent a tissue site using a pressure switch is disclosed. In another example, a system for applying negative pressure to a tissue site using a pressure switch is disclosed.

Apparatus and methods for regulating negative pressure in a negative pressure wound therapy system

Provided are systems and methods for delivery of fluid to a wound therapy dressing. In exemplary embodiments, a pressure source provides negative pressure to a wound dressing and a biasing mechanism provides positive pressure to a fluid reservoir.
