A syringe device with preferred and alternate embodiments structured to store, mix (if appropriate), and dispense multiple compounds (fluids, gels, suspensions, powdered solids, etc.) without the need for multiple syringes or the repeated use of a syringe. In a first embodiment, the device stores two separate compounds for use and mixes the compounds before dispensing the combined mixture. In a second embodiment, the device stores two separate fluids for use and dispenses the first fluid followed sequentially by dispensing the second. The device may be used with a variety of dispensing structures such as an applicator or a cannula (syringe needle). The present invention finds specific application, for example, in a syringe device for storing and combining a diluent with a lyophilized drug/vaccine. Overall, the device structures a unique arrangement of chambers and channels for the accurate storage, mixing, and dispensing of multiple compounds (fluids, gels, suspensions, powdered solids, etc.).
A dual chamber syringe device for storing, mixing, and dispensing multiple compounds from one device, the dual chamber syringe device comprising:
