Delivering and/or receiving fluids
First Claim
1. 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.

Abstract
The present invention generally relates to receiving bodily fluid through a device opening. In one aspect, the device includes a flow activator arranged to cause fluid to be released from a subject. A deployment actuator may actuate the flow activator in a deployment direction, which may in turn cause fluid release from a subject. The flow activator may also be moved in a retraction direction by a retraction actuator. In one aspect, the device may include a vacuum source that may help facilitate fluid flow into the opening of the device and/or may help facilitate fluid flow from the opening to a storage chamber. In one aspect, a device actuator may enable fluid communication between the opening and the vacuum source and the flow activator may be actuated after the enablement of fluid communication.

39. A device for receiving fluid from a subject, the device comprising:
-
a device actuator; a housing including a flow activator and an opening, 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 arranged to move the flow activator in a retraction direction, wherein the flow activator, the deployment actuator, and the retraction actuator are substantially concentrically aligned. - View Dependent Claims (40, 41, 42, 43)
