Abstract
A biological fluid sampling device for collecting a blood sample from a separate vascular access device and for ejecting a portion of the collected sample to a point-of-care testing device for analysis is provided. The biological fluid sampling device includes a body enclosing a reservoir. The reservoir has an internal volume sufficient to contain enough blood for use in a diagnostic test. The sampling device further includes: an access lumen extending from a distal end of the body for establishing fluid communication between a separate vascular access device and the reservoir; an outflow lumen also in fluid communication with the reservoir; and a removable vented cap attached to the outflow lumen including a gas permeable vent in gaseous communication between the reservoir and ambient air. In addition, several sample and transfer devices are provided for obtaining a sample from a subject and transferring the sample to a point-of-care testing device.
