Medical devices with visual and tactile indicators

Abstract A syringe comprising: a syringe barrel having a distal end, a distal tip, an open proximal end, a barrel sidewall extending between the distal end to the open proximal end and defining a chamber, the distal end of the syringe barrel including a distal wall; a connector extending distally from the syringe barrel at the distal wall and including a visual and tactile feature on an outside surface of the connector that is an indicator of a connection type of the connector to a secondary component, the visual and tactile feature having a 3 dimensional shape that indicates an insertion motion for engaging the connector with the secondary component, and the connection-type being defined by an inside surface of the connector; wherein the visual and tactile feature is one or more grooves or projections relative to the outside surface of the connector that are substantially parallel to a longitudinal axis of the syringe and the connection-type is a slip-type connection. 200--, 2 0 0 - 206 214 204 210 210 210
