Abstract: A catheter assembly includes a hollow needle having a sharpened distal tip which is movable between a position in which the needle is located within a housing and a patient penetrating position in which the distal tip extends beyond the distal end of a catheter. The catheter and a catheter hub form a catheter assembly which is supported on a catheter hub support.The catheter hub support is a one-piece molding and includes a gaskets and means that wipe the outside of the needle when the needle is withdrawn from the patient back within the housing to a needle protected position. The function of gasket means is to retard the flow of blood between the catheter hub and the catheter hub support.
