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.

31. A device for receiving fluid from a subject, comprising:
-
a housing including an opening to receive fluid into the housing; a device actuator; a vacuum chamber in the housing that is at a pressure less than ambient pressure prior to actuation of the device actuator; one or more needles being arranged to cause fluid to be released from the subject; a deployment actuator to move the one or more needles in a deployment direction toward or through the opening; and a membrane sealingly separating the opening from the vacuum chamber, the one or more needles being coupled to the membrane, wherein actuation of the device actuator actuates the deployment actuator to move the one or more needles in the deployment direction. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)

39. A device for receiving fluid from a subject, comprising:
-
a housing including an opening to receive fluid into the housing; a device actuator; one or more needles being arranged to cause fluid to be released from the subject; a retraction actuator to move the one or more needles in a retraction direction away from the opening; and a rotatable element that prohibits the retraction actuator from moving the one or more needles in the retraction direction prior to actuation of the device actuator and rotates relative to the housing to permit the retraction actuator to move the one or more needles in the retraction direction. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
