Abstract

This disclosure relates to drug delivery devices and related systems and methods. In some aspects, a drug delivery device includes a drug vial holder and a mechanism configured to compress a drug vial between upper and lower members of the drug vial holder.

Claims

1. A method, comprising:

inserting a spike through a seal of a drug vial to allow fluid communication between an interior of the drug vial and a channel defined by the spike; and

deforming a portion of the seal away from an interior of the drug vial such that the deformed portion of the seal forms a concave shape or dish shape to facilitate removal of drug from the interior of the drug vial, wherein deforming the portion of the seal away from an interior of the drug vial comprises using a mechanism to move the spike relative to the drug vial.

2. The method of claim 1, wherein the seal is a rubber seal.

3. The method of claim 1, wherein deforming the portion of the seal comprises using the spike to apply a force to the portion of the seal.

4. The method of claim 3, wherein the force is a frictional force.

5. The method of claim 4, wherein moving the spike relative to the vial comprises applying a force to a body portion of the drug vial in a direction opposite the force applied to the portion of the seal.

6. The method of claim 1, further comprising maintaining the seal in a compressed state while inserting the spike through the seal.

7. The method of claim 6, wherein the seal is compressed between a cap of the drug vial and a neck portion of the drug vial.

8. The method of claim 6, wherein the seal is compressed between a cap of the drug vial and a body portion of the drug vial.

9. The method of claim 1, wherein the mechanism comprises a spring.

10. The method of claim 1, further comprising removing drug from the drug vial while the portion of the seal is deformed and forms a concave shape or dish shape.
