Delivering and/or receiving fluids
First Claim
1. A device for receiving fluid from a subject, comprising:
- a device actuator;
a housing including an opening to receive fluid into the housing;
a vacuum source;
a flow path fluidly coupleable to the vacuum source to cause fluid to be drawn into the opening and along the flow path;
a membrane positioned along the flow path downstream of the opening that permits passage of air but prevents passage of liquids; and
one or more needles arranged to be inserted into a subject to cause fluid to be released from the subject.

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.
