The wavelengths are chosen such that hemoglobin within a blood vessel reduces the reflected light intensity different amounts according to an oxygen content of the hemoglobin. The intensities of one or both reflected lights is used to detect the presence of a blood vessel and a difference or a ratio of the intensities is used to identify the blood vessel as a vein vs an artery.

Automated Guidewire Extraction Systems and Methods
Catheter placement assemblies having automatic guidewire disengagement can include a handle and seal housing assembly defining a needle lumen and guidewire lumen. Once the vasculature is accessed, the guidewire advances through the handle guidewire lumen to a target location. The needle is withdrawn proximally through the handle needle lumen with a first force. When the needle tip is withdrawn into the seal housing, the seal housing locks to the needle tip. Applying a second, greater force urges the seal housing to disengage the handle. The seal housing is retained in place by a detent and/or timing lock mechanism. As the seal housing is urged proximally, a support pin retains the guidewire in place causing the guidewire to automatically disengage the seal housing. The seal housing mitigates needle stick injuries and allows the needle and seal housing assembly to be removed, allowing for unobstructed advancement of the catheter over the guidewire.
