Embodiment Construction

[0132] Devices and methods for automated drug injection are described herein. In some embodiments, a device includes a housing, a drug container disposed in the housing, and an actuator. An actuator is configured to be disposed within the housing and to move the drug container within the housing. The actuator includes a release member and an energy storage member. The energy storage member, which may be a compressed gas container, has a first position and a second position. When in the first position, the energy storage member has a first potential energy. When in the second position, the energy storage member has a second potential energy that is less than the first potential energy. The energy storage member is configured to convert a portion of the first potential energy into kinetic energy when moving from the first position to the second position to move the drug container within the housing. The longitudinal axis of the energy storage member is offset from the longit...

Abstract

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.

Description

technical field [0001] The present invention relates generally to a medical device, and more particularly to a drug delivery device for automatically injecting a drug into a patient's body. Background technique [0002] Exposure to certain substances such as peanuts, shellfish, bee venom, certain medications, toxins can cause allergic reactions in some individuals. This allergic reaction may sometimes lead to anaphylactic shock, which can cause a dramatic drop in blood pressure, hives, and / or severe airway narrowing. Therefore, responding quickly to mitigate the effects of this exposure can prevent injury and / or death. For example, in certain instances, an injection of epinephrine (ie, adrenaline) can substantially and / or completely alleviate an allergic reaction. In other cases, for example, injecting an antidote to a toxin can greatly reduce and / or eliminate the harm potentially caused by the exposure. [0003] Because emergency medical facilities may not be available w...
