Embodiment Construction

[0014] Referring to the drawings, there is shown a valve 10 for allowing mixing of at least two components. As discussed further below, valve 10 is particularly useful for reconstituting one or more medicaments, wherein one component is a wet (e.g., liquid) suitable for reconstituting a dry (e.g., lyophilized powder) component. ) components. Valve 10 may be used in the barrel of a syringe such as a syringe or pen injector (ie, a medical syringe), or in the barrel of a drug container. As will be appreciated by those skilled in the art, valve 10 may be used to allow various components, for example one or more wet components and / or One or more dry ingredients, which may be in powder or granular form, are mixed.

[0015] Valve 10 generally includes a body 12 and a poppet 14 . refer to Figure 6 and 7 , the body 12 is configured to be in a sliding fluid-tight engagement with the surrounding cylinder 16 . Barrel 16 may be the barrel of a syringe or a drug container. The body ...

Abstract

A valve is provided herein for permitting mixing of at least two components, the valve including a body configured for slidable liquid tight engagement with an injector or drug cartridge barrel. The body includes a proximal end, a distal end, and a channel extending therebetween, the channel having a proximal portion and a distal portion. A poppet is sealingly and slidably disposed in the channel to selectively move between first and second positions. The poppet includes a proximal end, a distal end, and a fluid channel, the fluid channel being defined in the poppet and extending from an outlet opening located distally of the distal end of the body. With the poppet being in the first position, the poppet defines a liquid tight seal in the channel such that liquid flow through the channel is prevented. With the poppet being in the second position, the fluid channel is in communication with the proximal portion of the channel so as to define a liquid flow path from the proximal portion of the channel to the outlet opening. Advantageously, with the subject invention, a valve is provided which permits controlled separation and mixing of substances in a standard injector or drug cartridge barrel, without any modification required thereto.

Description

technical field [0001] The present invention relates to a valve for mixing at least two substances in a medical syringe or drug container. Background technique [0002] Certain drugs or agents (the terms are used interchangeably herein) are preferably provided in powdered or dry form (eg, lyophilized form) and require reconstitution prior to administration. For example, lyophilized drugs are often supplied in a lyophilized form that requires mixing with a diluent to reconstitute the substance into a form suitable for injection. Medicaments may also be provided in other dry or powder forms requiring reconstitution. [0003] Alternatively, the drug may be provided as a multi-component system that requires mixing prior to administration. For example, one or more liquid (e.g., flowable (slurry or liquid)) components that require mixing prior to administration may be provided in a pharmaceutical container or delivery device, and / or dry (e.g., powder or granular ) components. ...
