    • The invention relates to a delivery pump (1) to be coupled to the neck (O) of a container (C) filled with a liquid (L) to be delivered comprising: a hollow body (3) defining a suction and compression chamber (4) for the liquid (L) having a suction duct (5) for the liquid (L), a tight piston (8) sliding in the hollow body (3), a delivery duct (6) for the liquid (L) communicating with the suction and compression chamber; valve means (7a, 7b) adapted to regulate inflow and outflow of liquid (L) into and from the suction and compression chamber (4), elastic means (9) arranged between the tight piston (8) and the hollow body (3). The delivery pump comprises first constraint means (10) fixed to the hollow body (3) and selectively cooperating with second constraint means (11) fixed to the tight piston (8) to define the stroke of said tight piston (8). The stroke can be varied according to the mutual position of the first (10) and second (11) constraint means.

    • A fluid dispenser used to administer fixed or adjustable doses of fluids in oral, intranasal, or injectable applications. The dispenser may be used to draw off fluid from a flexible or rigid bulk container or to draw fluid from a mounted flexible or rigid container such as a sealed-end bag or bottle, or a threaded bag or bottle. The fluid dispenser generally comprises: a connection member communicatively connected to a fluid source container; a body member having a dose cylinder communicatively connected to the connection member; a piston member operationally related to the dose cylinder and spring biased in an extended position; and a trigger member attached to the piston member and communicatively connected to the dose cylinder through the piston member. The dispenser may include a guide positioned on the connection member. The guide includes a platform portion and a guide portion, both of which being adapted to form a container passage. The dispenser may also include a sealed chamber mounted on the connection member. The sealed chamber has a first tip, a second tip, and a movable seal positioned within the sealed chamber. The movable seal forms a first reservoir proximate to and in fluid communication with the first tip and a second reservoir proximate to and in fluid communication with the second tip. Both of the tips are adapted to be selectively connected in fluid communication with the fluid communication channel and with an external fluid source.
    • 用于在口腔,鼻内或可注射应用中施用固定或可调剂量的流体的流体分配器。 分配器可以用于从柔性或刚性散装容器中抽出流体,或者从安装的柔性或刚性容器(例如密封端袋或瓶或螺纹袋或瓶)中抽出流体。 流体分配器通常包括:连通构件,其连通地连接到流体源容器; 身体构件,其具有与所述连接构件通信地连接的剂量筒; 活塞构件,其与所述剂量圆筒和弹簧偏置在延伸位置中有关; 以及触发构件,其附接到所述活塞构件并且通过所述活塞构件与所述剂量筒连通地连接。 分配器可以包括定位在连接构件上的引导件。 引导件包括平台部分和引导部分,两者都适于形成容器通道。 分配器还可以包括安装在连接构件上的密封室。 密封室具有位于密封室内的第一末端,第二末端和可移动密封件。 可移动密封件形成靠近并与第一末端流体连通的第一储存器和靠近第二末端并与第二末端流体连通的第二储存器。 两个尖端适于选择性地连接成与流体连通通道和外部流体源流体连通。
