Abstract

A wearable automatic injection device is provided for administering a final medicament to a patient. The wearable automatic injection device comprises a housing, an injection assembly for injecting the patient with the final medicament, a container holding a bulk intermediate medicament and a diluent to be mixed to form the medicament, and a mixing mechanism for mixing the bulk intermediate medicament and the diluent in the container to form the final medicament prior. A system for administering a final medicament to a patient is also provided. The system comprises a container, a mixing mechanism for mixing a bulk intermediate medicament and a diluent in the container to form the final medicament, and a wearable automatic injection device configured to receive the container.

First claim

What is claimed is:

1. A system for administering a final medicament to a patient, the system comprising:
a first container holding a bulk intermediate medicament;
a second container holding a diluent to be mixed with the bulk intermediate medicament to form the final medicament;
a mixing mechanism including a mixing container for mixing the bulk intermediate medicament and the diluent in the mixing container to form the final medicament prior to injection; and
a wearable automatic injection device separable from the first container, the second container, and the mixing mechanism comprising:
a housing;
a port to receive the mixing container containing the final medicament;
an injection assembly for injecting the patient with the final medicament; and
an activation mechanism for initiating the injection assembly for administering the final medicament to the patient.

2. The system of claim 1 , wherein the mixing mechanism is initiated based on a user actuating a button on the mixing mechanism.

3. The system of claim 1 , wherein the mixing mechanism is initiated based on a user actuating a wireless remote in wireless communication with the mixing mechanism.

4. The system of claim 1 , further comprising a turbidity meter disposed in the mixing mechanism to automatically verify mixing of the bulk intermediate medicament and diluent.

5. The system of claim 1 , further comprising a piezoelectric element coupled to the mixing container and energized by the mixing mechanism when the mixing mechanism is initiated, the piezoelectric element configured to cause the diluent to cavitate and mix with the bulk intermediate medicament.
