Abstract
injection device includes a housing having a tissue-engaging surface and an opening in the tissue-engaging surface, a fluid conduit having a piercing end movable through the opening from a retracted configuration to a deployed configuration. The injection device also comprises a vial, an activating switch movable from a deactivated to an activated configuration, a touch sensor disposed on the tissue-engaging surface and configured to detect contact with skin, a controller coupled to a motor, the controller configured to receive a trigger and cause the motor to move the piercing end to move through the opening and to cause the fluid conduit to come into fluid communication with the vial. The trigger includes receiving a first indication that the activating switch has been moved to the activated configuration and a second indication that the touch sensor is in contact with skin while the activating switch is in the activated configuration. The current invention prevents accidental injections or user error when activating an injection procedure in auto injectors.
Claims (3)
1. An ion device, comprising: a housing having a -engaging surface and an opening in the tissueengaging surface; a fluid conduit having a piercing end that is movable through the opening from a retracted configuration to a deployed configuration; an activating switch ured to be moved from a deactivated configuration to an activated configuration; a touch sensor disposed on the tissue-engaging surface and configured to detect contact with skin; a vial; a motor configured to cause the piercing end to move through the g and to cause the fluid conduit to come into fluid communication with the vial; and a controller d to the motor, wherein the controller is configured to: in response to a trigger, cause the motor to move the piercing end from the retracted configuration to the deployed configuration and to move the fluid conduit into fluid communication with the vial; wherein the trigger includes receiving a first indication that the activating switch has been moved from the deactivated configuration to the activated configuration and a second indication that the touch sensor is in contact with skin while the activating switch is in the activated configuration.
2. The injection device of claim 1, wherein the controller is further configured to: without requiring intervention by a user after g the motor to move the piercing end from the retracted configuration to the deployed configuration, automatically cause the motor to retract the piercing end.
3. The injection device of claim 2, wherein a time between movement of the piercing end from the retracted configuration to the deployed configuration and retraction of the piercing end is between 20 and
