Abstract: A device for mixing and delivering a solution includes a tubular barrel that includes a first end, a second end, and interior compartment. A first plunger is positionable at the first end, is moveable within the interior compartment, and includes a spike protruding into the interior compartment, the spike having an end configured for piercing a membrane. A second plunger is positionable within the barrel, moveable within the interior compartment, and has a pierceable membrane. The second plunger and the second end form a first area housing a first solution and the first and second plungers form a second area housing a second solution. The first and second plungers are slidably arranged within the interior area such that moving the first plunger toward the second plunger causes the spike to pierce the pierceable membrane and push the second solution through the pierced membrane to mix with the first solution.

Abstract: The presently disclosed subject matter is directed to a device for dispensing a mixture of a first composition (e.g., an anesthetic) and a second composition (e.g., a diluent buffer, a second drug, or a solution). The device comprises a plunger that slidably engages with the interior of the device barrel at a first end. The second end of the device barrel includes a flexible container configured to house one or more solutions (e.g., sodium carbonate). The flexible container comprises a membrane positioned adjacent to the interior of the barrel. The flexible container can be manipulated by the user, rupturing the membrane. In this way, the first and second solutions are intermixed within the interior of the barrel, and can be administered to a patient.
