ABSTRACT:
A blood flow detector produces a signal in response to pulsatile blood flow to provide means for positioning a slot in a plate in alignment with a patient's artery. Pressing the plate against the patient's skin retains the artery in alignment with the slot for puncturing. A groove in the bottom of the plate holds the artery in position while a first slot located at one end of the groove is used to guide an instrument toward the artery. A second slot adjacent the first slot is spaced a predetermined distance from the first slot so that by guiding a needle through the second slot the vein corresponding to an artery can be penetrated.
