    • A system is illustratively described herein that generally comprises a vacuum chamber, an ambient pressure chamber, a valve configured for unidirectional flow from the vacuum chamber to the ambient pressure chamber during a charging stroke, and a liquid filter configured to retain liquid in the pump. In some embodiments, the liquid filter is configured to retain liquid in the vacuum chamber during the charging stroke. In other embodiments, it may be configured to retain liquid in the ambient pressure chamber during an operating stroke. In more particular embodiments, a piston may be disposed between the vacuum chamber and the ambient pressure chamber, a passage may fluidly couple the vacuum chamber and the ambient pressure chamber, and the valve can be configured to control fluid flow through the passage. Additionally, a lumen may couple the vacuum chamber to a dressing to deliver negative pressure to the dressing in some illustrative embodiments.
    • 本文说明性地描述了一种系统,其通常包括真空室,环境压力室,构造成用于在充气冲程期间从真空室到环境压力室的单向流动的阀以及被配置为将液体保持在泵中的液体过滤器。 在一些实施例中,液体过滤器构造成在充气冲程期间将液体保持在真空室中。 在其他实施例中,其可以被配置为在操作冲程期间将液体保持在环境压力室中。 在更具体的实施例中,活塞可以设置在真空室和环境压力室之间,通道可以流体地联接真空室和环境压力室,并且阀可被配置成控制通过通道的流体流动。 此外,在一些说明性实施例中,腔可以将真空室耦合到敷料以向敷料输送负压。

    • In one example embodiment, a system for treating a tissue site is disclosed that may comprise a manifold including a non-porous film having a plurality of closed cells defined by a sealed region perforated with apertures extending through the sealed region, wherein the manifold is adapted to contact the tissue site. The system may further comprise a cover adapted to provide a fluid seal between a therapeutic environment including the manifold proximate one side of the cover and a local external environment on the other side of the cover. In one embodiment, the plurality of closed cells is adapted to form distal channels with the cover and the apertures are adapted to provide fluid communication between the distal channels and the tissue site. The system may further comprise a negative-pressure source fluidly coupled to the therapeutic environment and adapted to provide negative pressure through the distal channels and the apertures to the tissue site. In another example embodiment, a method for treating a tissue site is disclosed comprising positioning a manifold including a non-porous film having a plurality of closed cells defined by a sealed region perforated with apertures extending through the seals to contact the tissue site. The method may further comprise covering the manifold and the tissue site with a drape to provide a fluid seal between a therapeutic environment including the manifold proximate one side of the drape and a local external environment the other side of the drape. The method may further comprise providing negative pressure from a negative- pressure source coupled to the therapeutic environment wherein the negative pressure is applied through the distal channels and the apertures to the tissue site.
