摘要: A pneumatic accumulator may be fluidly coupled between a negative-pressure source and a dressing of a therapy system. The pneumatic accumulator may have a small volume and one or more deformable members that can deform under negative pressure, reducing the volume of the pneumatic accumulator. The pneumatic accumulator can smooth a pressure wave created by the negative-pressure source. The pneumatic accumulator may also provide additional negative-pressure storage capacity to the therapy system. For example, if a leak develops at the dressing, some of the negative pressure stored in the pneumatic actuator may be supplied to the dressing. The pneumatic accumulator may allow for reduced runtime of the negative-pressure source, leading to increased electrical efficiency.
