  • Drug disposal and verification device
    Patent number: 7968062
    Abstract: A drug disposal and verification device includes a first chamber and a second chamber. The first chamber has an injection port for receiving wasted drug solution and a disposal volume. A positive displacement flow measuring device positioned between the injection port and the disposal volume is used to measure the volume of wasted drug solution injected into the device. The positive displacement flow measuring device is also adapted to divert a small portion of the wasted drug solution to the second chamber. The second chamber holds a breakable test reagent ampule for quantitative testing of the wasted drug solution. The disposal volume of the first chamber may include at least one test strip for qualitative testing of the wasted drug solution.
