Abstract: A surgical tissue therapy device includes a sealant layer and a collection chamber. The sealant layer functions so as to create a sealed enclosure or space between it and the surface of a patient by forming, preferably, an airtight seal around a surgical area of skin trauma. The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer. The collection material may comprise a material and/or a configuration that permits length changes based upon the length of the corresponding surgical wound or incision.

Abstract: Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing. Fourth, the system may be configured to include an indicator which visually makes clear whether reduced pressure is being applied or not. Fifth, the system is configured to minimize the profile of the dressing system.

Abstract translation: 外科组织治疗装置包括密封剂层和收集室。 密封剂层的作用是通过在皮肤创伤的外科手术区域周围形成优选的气密密封来在其与患者的表面之间形成密封的外壳或空间。 封闭的切口组织治疗装置还包括收集室，其可以包括具有多个纵向间隔的开口的细长管状室。 收集室可以构造成与密封剂层和皮肤创伤区域流体连通，并且用于分配施加到手术闭合的皮肤创伤区域上的负压。 优选地，通过膨胀封闭空间的体积并由此降低密封剂层下面的空气分子的密度来降低密封层下方的压力。 收集材料可以包括基于相应的手术伤口或切口的长度允许长度变化的材料和/或构造。

Abstract: Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.
