Abstract:
1. A portable microbubble and drug mixing device, comprising: a flexible outer container comprising an interior chamber for accommodating a drug, wherein the flexible outer container has a tensile strength at break less than or equal to approximately 15 MPa; and a rigid inner container within the flexible outer container, the rigid inner container comprising an interior chamber for accommodating microbubbles and wherein the rigid inner container has a tensile strength at break greater than or equal to approximately 20 MPa and is capable of storing microbubbles at a concentration higher than or equal to approximately 5×10 wherein the rigid inner container is configured to separate the microbubbles in the interior chamber of the rigid inner container from the drug in the interior chamber of the flexible outer container until a point of mixing; and wherein the mixing device is configured to enable releasing the microbubbles from the interior chamber of the rigid inner container into the interior chamber of the flexible outer container and mixing the microbubbles and drug in the interior chamber of the flexible outer container at and after the point of mixing; and wherein the rigid inner container comprises a release window, and the mixing device further comprises a tether connected to the release window and extending to an exterior of the flexible outer container, allowing the release window to be opened by pulling the tether.
