用于治疗创伤的手动致动的减压系统
摘要：
用在用于治疗组织部位(102)处的组织的减压系统(100)上的手动致动的恒定减压装置包括可操作以在压缩位置和延伸位置之间运动的柔性可折叠构件(146)。可折叠构件可以被放置于在压缩位置和延伸位置之间运动的承载器构件动器构件被恒定力偏移构件，例如恒定力螺旋弹簧，驱动为彼此远离。当装置从压缩位置运动至延伸位置时，恒定的减压被产生且被传送至减压口(154)。还提供了制造手动致动的恒定减压装置的方法、系统以及治疗组织部位的方法。(156)和滑动器构件(168)之间。承载器构件和滑
摘要（英）：

A manually-actuated, constant reduced-pressure apparatus for use with a reduced- pressure system for treating tissue at a tissue site includes a flexible, collapsible member that is operable to move between a compressed position and an extended position. The collapsible member may be disposed between a carrier member and a slider member that move between a compressed position and an extended position. The carrier member and slider member are urged away from each other by a constant-force biasing member, e.g., a constant force coil spring. As the apparatus moves from the compressed position to the extended position, a constant reduced-pressure is generated and delivered to a reduced-pressure port. Systems, methods of manufacturing a manually-actuated, constant reduced-pressure apparatus, and methods of treating a tissue site are also provided.
