A electrical isolation member for an electronic auto-injector

An auto-injector 4002 is first enabled by removing the needle guard 4810 and the safety lock 4710. As illustrated by arrow AA in FIG. 57, the needle guard 4810 is removed by moving it distally. The sheath retainer 4840 includes an actuator 4864 that is received by an opening 4862 in the isolation tab 4860. Accordingly, when the sheath retainer 4840 is moved distally away from the base 4520, the isolation tab 4860 is removed from the area between the first electrical contact portion 4936 of the printed circuit board 4922 and the first surface 4964 of one of the batteries 4962. In this manner, the batteries 4962 can be operatively coupled to the electronic circuit system 4920 when the needle guard 4810 is removed, thereby actuating the electronic circuit system 4920.

An auto-injector to mix and/or create an injectable medicament from two or more separate medicaments.

The vial 13262 contains one wet substance (such as sterilized water) and one dry substance. (such as glucagon powder). Trigger 13468 at the side of the housing initiates the reconstitution and mixing of the two substances. Trigger 13468 activates a spring 13436 forced toward the proximal end 13112 of the housing 13110. As the spring 13436 is forced upward, the solid member 13362 and therefore plunger/membrane 13282 can be forced upward toward the proximal end 13264 of the vial 13262. This force can cause wet substance to bypass the plunger/membrane 13282, moving down toward the distal end 13266 of the vial 13262 and can thereby cause the wet substance to mix with the dry substance forming the new injectable medicament. The user can shake the entire housing 13110 in order to aid in this mixing process. The user can then take off the safety tab 13710 located at the base of the auto-injector 13002 and operate the auto-injector.
