Patent number: 11938304Abstract: Impact testing apparatuses are disclosed which simulate and measure various impact-related events associated with the operation of a drug delivery device. The impact testing apparatus may include an impactor configured to simulate a plunger rod of the drug delivery device, and a guide sleeve configured to receive a syringe corresponding to the drug delivery device. The syringe may have a proximal end, a distal end defining an outlet, and an interior chamber extending between the proximal and distal ends and carrying a plunger. Additionally, the impact testing apparatus may include an energy source configured to reduce a distance between the impactor and the plunger so that the impactor strikes the plunger. Various sensors may be included to measure characteristics of one or more impacts caused by the impactor. Methods of impact testing a syringe filled with a fluid and carrying a plunger are also disclosed.Type: GrantFiled: November 30, 2022Date of Patent: March 26, 2024Assignee: AMGEN INC.Inventors: Julian Jazayeri, Sean Fitzgibbon, Joshua Tamsky, Christopher R.

Patent number: 11241539Abstract: An injection device, method, and system for drug delivery includes a container for storing a drug, the container having a stopper movably disposed in the container for expelling the drug; an injection drive mechanism having a plunger for acting on the stopper and an energy source having a first selected potential energy for exerting a force on the plunger to cause the plunger to act on the stopper to expel the drug; and a plunger loading mechanism for substantially preventing the plunger from accelerating to a predetermined velocity before it acts on the stopper. The plunger loading mechanism may be a spring having a second selected potential energy for reducing or eliminating a distance between the plunger and the stopper, prior to the plunger accelerating to the velocity.
