Abstract: A safety device for injection devices is described. The safety device includes a sleeve extending along a longitudinal axis of the injection device's body, at least partially enclosing the injection device's needle and body, and including a guide slot; a collar attached to a distal end region of the body and locking the safety device in an axial direction; and a cap that can be arranged at least in part over the sleeve to prevent the body from moving relative to the sleeve. The cap includes a receptacle for the needle. The collar includes a guide pin that engages the guide slot. The collar can be arranged to rotate relative to the sleeve, and the receptacle of the cap can engage the collar and prevent the collar from rotating. The sleeve and the collar can each include a lock.

Abstract: Modifications of an inhaler and method of use thereof are described. In some embodiments, an inhaler may include one or more systems and/or methods that function to inhibit a child from accessing medicant from an inhaler. A system may function to inhibit a child from accessing an opening of an inhaler from which medicants are dispensed. In some embodiments, a system may inhibit a child from removing a cap for an inhaler. A system may function to inhibit a child from actuating an activation mechanism for an inhaler. A system may function to inhibit a user and/or a child from accidentally actuating an activation mechanism for an inhaler multiple times possibly resulting in an overdose. A system may function to inhibit an activation mechanism for an inhaler from actuating after the activation mechanism has been actuated a predetermined number of times. An inhaler may include a security fitting which functions to permanently plug an inhaler once a prescribed user is finished with the inhaler.
