    摘要： A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A first hydrophobic filter is positioned at an opening of the canister to detect a canister full condition. A second hydrophobic filter is positioned between the first filter and the negative pressure source to prevent contamination of the non-disposable portion of the system by exudates being drawn from the wound. An odor filter is positioned between the between the first and second hydrophobic filters to aid in the reduction of malodorous vapors. A securing means is supplied to allow the portable housing to be secured to a stationary object, such as a bed rail or intravenous fluid support pole. A means for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A means for varying pump drive frequency and a means for managing a portable power supply are provided to increase battery life and improve patient mobility.

    摘要翻译： 用于刺激组织愈合的系统包括定位在伤口腔内的多孔垫，以及固定在垫上的气密敷料，以便向伤口腔提供气密密封。 导管的近端可连接到敷料。 导管的远端可连接到负压源，负压源可以是容纳在便携式外壳内的电动泵或壁吸力。 沿着管道定位罐，以在施加负压期间保持从伤口部位抽吸的渗出物。 第一疏水过滤器位于罐的开口处，以检测罐全部状态。 第二疏水性过滤器定位在第一过滤器和负压源之间，以防止从伤口抽出的渗出物对系统的非一次性部分的污染。 位于第一和第二疏水过滤器之间的气味过滤器位于有助于减少恶臭蒸气之间。 提供固定装置以便便携式外壳固定在固定物体上，例如床轨或静脉注射液支撑杆。 提供了随时间自动振荡压力的手段，以进一步增强和刺激开放性伤口的愈合。 提供用于改变泵驱动频率的装置和用于管理便携式电源的装置以增加电池寿命并提高患者的移动性。
