Abstract
A mechanism and method for preventing premature activation of an action includes a safety device. The safety device includes a housing that is arranged to enable such an action when the housing is in a desired orientation (e.g., horizontal, vertical). The housing includes a bowl having a concave cavity, a ball located in the cavity and a trigger having an actuator and a sleeve arranged to slide about the ball when the ball is in a predetermined position of the cavity to move the actuator and initiate the action.
Claims31
A safety device for initiating an action, comprising:
- a housing;
- a trigger within said housing, said trigger movable from a first position to an activation position, wherein when said trigger is in said activated position, said trigger initiates the action;
- and
- an orientation unit in communication with said housing and said trigger, said orientation unit enabling movement of said trigger from said first position to said activated position only when said housing is in a predetermined three dimensional orientation.
A fluid delivery device, comprising:
- a housing arranged for injecting a fluid into an injection site;
- a trigger within said housing, said trigger movable from a first position to an activation position, wherein when said trigger is in said activated position, said trigger initiates the action of injecting the fluid;
- an orientation unit in communication with said housing and said trigger, said orientation unit enabling movement of said trigger from said first position to said activated position only when said housing is in a predetermined three dimensional orientation;
- and
- an injection assembly within said housing and in communication with said trigger, said injection assembly held under a releasable bias and arranged to expel the fluid from said delivery device upon release of the bias.
A method of ejecting a fluid from a delivery device, the delivery device including a housing, a trigger, an orientation unit, and an injection assembly, the housing arranged for injecting a fluid into an injection site, the trigger located within the housing, the orientation unit being in communication with the housing and the trigger, the injection assembly located within the housing and in communication with the trigger, the injection assembly held under a releasable bias and arranged to eject the fluid from the delivery device upon release of the bias, the method comprising:
- (a) enabling movement of the trigger from a first position to an activation position only when the housing is in a predetermined three dimensional orientation;
- (b) activating the injection assembly by releasing the bias by the movement of the trigger;
- and
- (c) providing an egress for ejecting the fluid from the delivery device.
