DELIVERING AND/OR RECEIVING MATERIAL WITH RESPECT TO A SUBJECT SURFACE

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. The flow activator may be actuated in a deployment direction by a deployment actuator, 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, an effector may enable fluid communication between the opening and the vacuum source and may do so in response to actuation of the flow activator.
