Abstract: A device is disclosed which aids in the stabilization of veins for puncturing. A device body is disclosed which may be constructed of any suitable lightweight and durable metal or resinous material which may be easily cast or formed and which possesses properties of strength and resiliency. A handle with a grip extending outwardly from the device body when said device is in the operative position may be engaged by a user's thumb or forefinger to stabilize the device body during use. A pair of elongated flanges displaced outwardly from the centerline of the device, spaced apart a selected distance, and terminating in contact surfaces, may be placed such that the subject vein may extend through a space present between the contact surfaces of the elongated flanges.
