| 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. |
