Problems solved by technology
[0005] Some conventional devices may fail to trigger or may delay triggering if the trigger button is not pressed with sufficient force - for example rheumatic patients who cannot apply very high force to the trigger button
Even when sufficient force is applied to the trigger button, some conventional devices may fail to trigger or delay triggering due to the normal construction of one or more structural components of the device

Embodiment Construction
[0101] Exemplary embodiments of the present invention minimize or eliminate false triggering of the automatic injection device causing delays in delivery of the injection to the user. Exemplary automatic injection devices ensure consistent successful firing of the automatic injection device. The exemplary embodiments provide, in part, a trigger mechanism assembly that minimizes or eliminates false triggers that cause delays in injection delivery. In some cases, unacceptable delivery delays range from four seconds to hours. Exemplary embodiments provide an automatic injection device that includes a trigger mechanism assembly that minimizes or eliminates delayed delivery of an injection once the trigger button is depressed, and provides for Methods of Minimizing or Eliminating Delayed Delivery of an Injection in an Automatic Injection Device Also provided are methods of using an automatic injection device that minimizes or eliminates delayed delivery of an injection to deliver ...

Abstract
Exemplary embodiments provide firing mechanism assemblies that minimize or eliminate a misfire of an automatic injection device that causes a delay in the delivery of an injection. Exemplary embodiments provide automatic injection devices including firing mechanism assemblies that minimize or eliminate a misfire that causes a delay in the delivery of an injection. Exemplary embodiments provide methods for minimizing or eliminating misfire that causes a delay in delivery of an injection in automatic injection devices. Exemplary embodiments also provide methods for using automatic injection devices that are free of a misfire that causes delay in delivery of a therapeutic substance into a patient's body.
Description
[0001] related application [0002] This application is related to and claims priority to U.S. Provisional Patent Application Serial No. 61 / 286,760, filed December 15, 2009, and U.S. Provisional Patent Application Serial No. 61 / 286,771, filed December 15, 2009, and relates to 2010 US Patent Application No. 12 / 770,557 filed April 29, 2009. The entire contents of the aforementioned applications are hereby expressly incorporated by reference into the present application. Background technique [0003] Automatic injection devices provide an alternative to manually operated syringes for delivering therapeutic agents into a patient and allowing the patient to self-administer the injection. Automatic injection devices are already used to deliver drugs in emergency situations, such as administering epinephrine to counter the effects of a severe allergic reaction. Automatic injection devices have also been described for use in the administration of antiarrhythmic drugs and selectivel...
