摘要： A hollow inner plunger (100) for use within a syringe-in-syringe mixing system for mixing a two-part dental composition. The hollow inner plunger includes a body having a continuous cylindrical wall (102) defining an internal chamber (108) for containing a first component (HOa). The body (100) includes a proximal end (104) and a distal end (106). A sealing plug and rupturable membrane (116) are disposed at the distal end of the body, and the sealing plug and rupturable membrane (116) are integrally formed together as a single piece (e.g. , formed of a single piece of elastomeric material). An associated syringe-in-syringe mixing system (124) includes a first plunger (126), the hollow inner plunger (100), and a syringe barrel (128) configured to contain a second component (HOb). When assembled, the first plunger (126) is slidably disposed within the hollow inner plunger (100), and the hollow inner plunger (100) is slidably disposed within the syringe barrel (128). The two components (110a, 110b) are initially separated by the rupturable membrane (116).

摘要： A venting syringe plunger assembly (100) for use with a syringe system allows for venting of gas from the syringe system during use. The plunger assembly (100) includes a hollow outer sleeve (102) having an interior surface, and an inner stem (104) having an exterior surface. At least a portion of the inner stem (104) is disposed within the outer sleeve (102) so as to be movable (e.g., slidable) within the outer sleeve (102). A venting passageway (106) is defined between the interior surface of the outer sleeve (102) and the exterior surface of the inner stem (104). The plunger assembly (100) also includes means (112) for selectively moving the inner stem (104) within the outer sleeve (102) so as to selectively open and close the venting passageway (106).

摘要： Time-indicating syringe mixing systems (100) for mixing, storing, and dispensing a two-part dental composition (108a, 108b) that becomes less stable upon mixing including a first plunger (102) comprising an elongate stem (110) and a plug (112) at a distal end of the elongate stem (110). A hollow chamber (104) is configured to contain a first component (108a). A hollow chamber of syringe barrel (106) is configured to contain a second component (108b). First plunger (102) is slidably disposed within hollow second plunger (104), which is slidably disposed within syringe barrel (106). A substantially flat label surface (114) is formed into cylindrical elongate stem (110) near a proximal end of cylindrical elongate stem (110). Providing a label surface (114) facilitates marking the date when components (108a, 108b) are mixed, so that thereafter shelf life may be easily monitored.
摘要翻译：时间指示注射器混合系统（100），用于混合，储存和分配在混合时变得不稳定的两部分牙科组合物（108a，108b），包括包括细长杆（110）和塞子（112）在细长杆（110）的远端处。中空室（104）构造成容纳第一部件（108a）。注射器筒（106）的中空腔被构造成包含第二部件（108b）。第一柱塞（102）可滑动地设置在中空的第二柱塞（104）内，其可滑动地设置在注射器筒（106）内。基本平坦的标签表面（114）在圆柱形细长杆（110）的近端附近形成为圆柱形细长杆（110）。提供标签表面（114）有助于标记组件（108a，108b）混合的日期，从而可以容易地监视保存期限。
