MEDICAMENT DELIVERY AND TRAINING CARTRIDGE SYSTEM AND MECHANISMS OF ACTUATION
First Claim
1. A medicament delivery system, comprising:
- a container for storing a medicament prior to use, the container having one or more openings therein, the container comprising;
a first housing for containing a medicament;
a stopper associated with the first housing;
a second housing, wherein the first housing is held within the second housing, and the first housing is movable relative to the second housing;
an injection member associated with a lower portion of the first housing;
a spring disposed between the first housing and the second housing; and
an actuation mechanism;
wherein the actuation mechanism interacts with the container to move the first housing relative to the second housing in a first direction, such that the spring is in a biased state, the injection member is ejected from the second housing traversing a first contaminant barrier, and move the stopper relative to the first housing in a first direction to deliver the medicament through the injection member, such that when the first housing moves relative to the second housing in a second direction, the spring is in an unbiased state and the injection member is retracted into the second housing to prevent an unintentional contact with the injection member.

Abstract
A medicament delivery system including a container for storing a medicament prior to use is provided. The container includes one or more openings therein, a first housing for containing a medicament, a stopper, a second housing, wherein the first housing is held within the second housing and the first housing is movable relative to the second housing. The system further includes an injection member a spring disposed between a lower portion of the first housing and a lower portion of the second housing, wherein an actuation mechanism interacts with the container to eject the injection member from the second housing, and the stopper moves relative to the first housing in a first direction to deliver the medicament through the injection member, and following injection, the injection member is retracted into the second housing to prevent an unintentional contact with the injection member.

25. A medicament delivery training system configured to provide stepwise instructions for using the system to a user in a particular sequence, the system comprising:
-
a reusable housing component configured to receive a container, said reusable housing component comprising a control interface, the control interface comprising at least one responsive member reactive to a user input; an actuation mechanism configured to interact with the container; a signal output component associated with the reusable housing component; and circuitry associated with the reusable housing component configured to control a provision of the stepwise instructions to the user in the particular sequence, wherein the container comprises a first housing, and a second housing, a spring disposed between a lower portion of the first housing and a lower portion of the second housing, and an injection member associated with the lower portion of the first housing, wherein the first housing is movable relative to the second housing; and
a stopper is associated with the first housing, said stopper being movable relative to the first housing, wherein the actuation mechanism interacts with the container to move the first housing in a first direction relative to the second housing to eject the injection member from the second housing, and the stopper in a first direction relative to the first housing. - View Dependent Claims (26, 27, 28, 29, 30)
