Abstract: A device that has a device body defining an opening at one end thereof, a storage chamber within the device body for storing multiple doses of a substance therein, and a sliding stopper, sealing engageable with the device body, through which the chamber is filled. The stopper has a body and a flexible portion, which may be in the form of a plurality of flexible members, extending therefrom. The flexible portion or members are movable between first and second positions. In the first position, during filling, the portion or members are substantially laterally extending from the stopper body and engaging the opening of the device body. Accordingly, the axial position of the stopper with respect to the device body is secured during filling of the chamber therethrough. In the second position, after filling, the portion or members are substantially axially-extending from the stopper body and disengaged from the rim or opening of the device body. Accordingly, the stopper is axially slideable through the body.
Abstract translation: 一种装置，其具有在其一端限定开口的装置主体，在装置主体内用于储存多个剂量的物质的储存室，以及滑动止动件，可与装置主体接合，通过该装置主体填充该容器。 止动器具有主体和柔性部分，其可以是从其延伸的多个柔性构件的形式。 柔性部分可在第一和第二位置之间移动。 在第一位置，在填充期间，该部分或部件基本上从止动体横向延伸并与装置主体的开口接合。 因此，塞子相对于装置主体的轴向位置在腔室通过其的填充期间被固定。 在第二位置，在填充之后，部分或部件基本上从止动体轴向延伸并与装置主体的边缘或开口脱离。 因此，止动件可轴向滑动通过本体。

Abstract: An injection member penetrates an elastic septum of a device defining a sealed, empty, sterile chamber in fluid communication with the septum. During penetrating, an annular interface is formed between the septum and the injection member extending axially between a penetration point on an interior surface of the septum in fluid communication with the sterile chamber, and an exterior surface of the septum engaging the injection member. The injection member is de-contaminated by (i) friction between the septum and injection member at the annular interface, and (ii) elongation of the septum at the annular interface. A substance is introduced through the injection member and into the sterile chamber of the device, the injection member is then withdrawn from the septum, the septum reseals itself at the resulting penetration aperture, and the chamber is maintained sterile throughout the foregoing steps.

Abstract: An apparatus for aseptic transfer of fluid therethrough. A first portion includes a closure and a piercing member comprising a hollow shaft for flowing fluid therethrough, and at least one port in fluid communication with the interior of the hollow shaft for passage of the fluid therethrough. The closure and/or the shaft is movable between (i) a first position wherein the closure closes the port(s), and (ii) a second position opening the port(s). A second portion includes a pierceable septum. The first and second portions are engageable such that the piercing member pierces the pierceable septum. When the pierceable member has at least partially penetrated the pierceable septum, the closure and/or the shaft moves from the first position to the second position for aseptical transfer of fluid.

Abstract: An apparatus for filling a device having a penetrable septum and a sealed chamber. The apparatus includes a filling member engageable with the penetrable septum to penetrate the septum, port(s), and a closure. The closure and filling member are movable between (i) a first position wherein the closure closes the port(s), and (ii) a second position opening the port(s). The filling member and/or septum is movable relative to the other between (i) a first position wherein the filling member is spaced from the septum, and (ii) a second position wherein the filling member is penetrated through the septum and in communication with the sealed chamber. A locking device is movable between (i) a locked position locking the closure and/or filling member in the first position, and (ii) an unlocked position allowing movement of the closure and/or filling member relative to the other and into the second position.

Abstract: A device and method are provided for storing substances separately, and for mixing the substances prior to use. The device defines at least one first chamber for receiving a first substance, and at least one second chamber for receiving a second substance. A first sealing portion is located between the first and second chambers and is movable between a closed position preventing fluid communication between the chambers, and an open position permitting fluid communication between the first and second chambers for mixing the substances. First and second penetrable and resealable portions in fluid communication with the first and second chamber(s), respectively, may be used for filling by penetrating them with an injection member and introduce the substances therethrough and into the respective chamber, and resealing the injection apertures and the substances within the respective chamber.
