BLOOD SAMPLING DEVICE

摘要

A blood sampling device useful for collecting a blood sample from a separate vascular access device is described herein. The blood sampling device includes a body shaped and sized for partial insertion into a separate vascular access device. The body includes a reservoir defined within the body, which has an internal volume sufficient to contain enough blood for use in a diagnostic blood test. The body also includes a gas permeable vent disposed on the body, in which the gas permeable vent is in gaseous communication with the reservoir. When connected to a separate vascular access device the blood sampling device collects a blood sample as blood flows into the reservoir from the separate vascular access device and as gases pass out the reservoir via the gas permeable vent.

主权项

1. A blood sampling device, comprising:
a body having an exterior wall forming a proximal end, a distal end, and a distal opening, the distal end being configured for coupling with a separate vascular access device; a reservoir, defined by the exterior wall of the body, the distal opening comprising an opening of the reservoir, an inner surface of the exterior wall defining a volume of the reservoir, the reservoir for collecting blood that flows from the vascular access device and into the reservoir via the distal opening; and a gas permeable membrane disposed within the exterior wall of the body, the membrane allowing gas to exit the reservoir through the membrane while blocking blood from exiting the reservoir thereby allowing the blood sampling device to be used as a vent plug for the vascular access device; wherein at least a portion of the exterior wall of the body is compressible to reduce the volume of the reservoir thereby forcing blood contained within the reservoir out through the distal opening.
