摘要： 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.

摘要： Methods and devices for treatment of damaged tissue are disclosed, including treatment of wounds by employing non-electrically powered, reduced pressure therapy devices. The devices are capable of generating a substantially constant reduced pressure with low tolerance for pressure fluctuations. Also disclosed herein are reduced pressure therapy systems that comprise an alarm system to detect the depleted state of the suction device and provide an alert to the patient and/or practitioner.

摘要： 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.

摘要： Described herein are alarm systems for suction devices for reduced pressure therapy. Alarms systems provide alerts to the patient and/or practitioner regarding the ability of the suction device to continue to provide negative pressure to a tissue region. Alarm systems comprise a sensor mechanism, which is capable of detecting the position of a slidable seal within the suction device, and generating an alert. Certain variations of alarms systems comprise magnetic field sensitive switches and/or electric switches. Other variations of alarm systems comprise rotary encoders to detect the motion and location of constant force springs, which signal the notification mechanism to issue alerts accordingly. Described herein are alarm devices configured to retain a suction device therein and to attach the suction device to a patient. The alarm devices disclosed herein detect the depleted state of the suction device and are capable of retaining the suction device in a plurality of orientations.
