    • A system (10) for stimulating the healing of tissue comprises a porous pad (11) positioned within a wound cavity (12), and an airtight dressing (13) secured over the pad, so as to provide an airtight seal to the wound cavity (12). A proximal end (16a) of a conduit (16) is connectable to the dressing (13). A distal end (16b) of the conduit (16) is connectable to a negative pressure source (14), which may be an electric pump housed within a portable housing (32), or wall suction. A canister (18) is positioned along the conduit (16) to retain exudates suctioned from the wound site (12) during the application of negative pressure. A first hydrophobic filter (20) is positioned at an opening of the canister (18) to detect a canister full condition. A second hydrophobic filter (22) is positioned between the first filter (20) and the negative pressure source (14) to prevent contamination of the non-disposable portion of the system by exudates being drawn from the wound. An odor filter (23) is positioned between the first and second hydrophobic filters (20, 22) to aid in the reduction of malodorous vapors. A securing means (34) is supplied to allow the portable housing (32) 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.
    • 用于刺激组织愈合的系统(10)包括定位在伤口腔(12)内的多孔垫(11)和固定在垫上的密封敷料(13),以便向伤口腔提供气密密封 (12)。 导管(16)的近端(16a)可连接到敷料(13)。 导管(16)的远端(16b)可连接到负压源(14),该负压源可以是容纳在便携式外壳(32)内的电动泵或壁抽吸。 沿着导管(16)定位罐(18)以在施加负压期间保持从伤口部位(12)吸入的渗出物。 第一疏水性过滤器(20)位于罐(18)的开口处,以检测罐全部状态。 第二疏水性过滤器(22)位于第一过滤器(20)和负压源(14)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。 臭味过滤器(23)位于第一和第二疏水过滤器(20,22)之间,以帮助减少恶臭蒸汽。 供应固定装置(34)以允许便携式外壳(32)固定到静止物体,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。
