A solution delivery device comprising:
- a container component having a proximally-extending engagement wall and an internal cavity with a size selected to contain a predetermined quantity of a first constituent, the container component further having a distal end with an external ejection connector port;
- a plug component configured for selective engagement with the container component in at least first and second operational modes, the plug component having a proximal end, a distal end, and a side wall having an outer surface disposed between the ends, the plug component further having an external inlet connector port substantially at the proximal end and an internal flow path from the inlet connector port to a plug outlet port, the plug component being formed on the distal end with a plug distal surface;
- and
- an elongated channel wall installed within the internal cavity of the container component to form an elongated mixing channel, the channel wall having a wall top surface and being located within the container component such that the mixing channel has a substantially closed bottom and an open top adjacent the wall top surface, the mixing channel having an input end in fluid communication with the plug outlet port and an output end in fluid communication with the ejection connector port;
- wherein in the first operational mode the plug component is partially inserted within the container component such that the plug distal surface is spaced from the wall top surface so as to facilitate the fluid communication between the internal cavity of the container component, and particularly the mixing channel, and the surrounding atmosphere;
- wherein the wall top surface of the elongated channel wall is located within the container component facing the plug component so that when the plug component and the container component are fully assembled together in the second operational mode as by a proximal end of the container component engaging the proximal end of the plug component, the plug distal surface contacts the wall top surface and substantially closes the top of the elongated mixing channel so that the only access to the first constituent is provided by the input and output ends of the mixing channel;
- and
- wherein forcing a second constituent through the inlet connector port with the device in the second operational mode causes the second constituent to flow through the internal flow path of the plug component and out the plug outlet port and into the input end of the mixing channel so as to mix with the first constituent, whereby the first and second constituents are sufficiently mixed as together traversing the mixing channel from the inlet end to the outlet end and then out through the ejection connector port as a delivery solution without the need for a separate mixing, shaking, reconstituting, or priming step.
