Claim:
A device for receiving fluid from a subject, the device comprising: a housing; a device actuator; a fluid transporter including an opening and a flow activator, the flow activator being arranged to cause fluid to be released from the subject and the opening being arranged to receive fluid into the housing; a deployment actuator including a bistable element coupled to the flow activator and arranged to move from a first stable state to a second stable state in response to actuation of the device actuator, wherein motion of the bistable element from the first stable state to the second stable state moves the flow activator in a deployment direction toward or through the opening, and wherein the bistable element is incapable of moving from the second stable state to the first stable state in the absence of an external force on the bistable element; and a retraction actuator constructed and arranged to move the flow activator in a retraction direction.
