Abstract: A controlled delivery syringe device includes a syringe barrel having a proximal end and distal end which defines a chamber for containing an injectable material. A plunger rod is associated with the syringe barrel and a plunger is secured thereto which is axially movable within the syringe barrel. A plurality of equally and sequentially spaced periodic features are associated with the plunger rod and a counter member is engageable with the periodic features. Application of a distally directed force to the plunger rod results in disengagement and reengagement of the counter member with the sequentially spaced periodic features on the plunger rod, enabling advancement of the plunger rod and plunger in the syringe barrel while providing tactile feedback of dose progression of the injectable material. A method of retrofitting a syringe with a device for injecting a metered dose of injectable material is also provided.

Abstract: A valve for permitting mixing of at least two components within a barrel is provided including a stopper configured for slidable liquid-tight engagement with an inner surface of the barrel. The stopper is moveable between a first position and a second position and includes a proximal end, a distal end, and a channel extending therebetween. The valve further includes a stationary body comprising a base and a stem, the stem being disposed within the channel of the stopper when the stopper is in the second position. When the stopper is in the first position, there is a liquid-tight seal in the channel, such that fluid flow through the channel is prevented. Movement of the stopper to the second position terminates the liquid-tight seal, thereby establishing fluid communication through the channel. A drug containing device and assembly for delivering a reconstituted drug are also provided herein.

Abstract: A valve (10) for permitting mixing of at least two components within a barrel (12) is provided including a stopper (20) configured for slidable liquid-tight engagement with an inner surface (13) of the barrel. The stopper is moveable between a first position and a second position and includes a proximal end (22), a distal end (24), and a channel (26) extending therebetween. The valve further includes a stationary body (30) comprising a base (32) and a stem (34), the stem being disposed within the channel of the stopper when the stopper is in the second position. When the stopper is in the first position, there is a liquid-tight seal in the channel, such that fluid flow through the channel is prevented. Movement of the stopper to the second position terminates the liquid-tight seal, thereby establishing fluid communication through the channel. A drug containing device and assembly for delivering a reconstituted drug are also provided herein.
Abstract translation: 提供一种用于允许在筒体（12）内混合至少两个部件的阀门（10），其包括被配置为与所述筒体的内表面（13）可滑动地液密接合的止动件（20）。 止动件可在第一位置和第二位置之间移动并且包括近端（22），远端（24）和在其间延伸的通道（26）。 阀还包括固定体（30），其包括基座（32）和杆（34），当止动器处于第二位置时，杆设置在止动件的通道内。 当止动器处于第一位置时，在通道中存在液密密封，使得流体流过通道被阻止。 止动件移动到第二位置终止液密密封，从而建立通过通道的流体连通。 本文还提供了用于递送重构药物的药物包含装置和组合件。
