<p>A catheter assembly 1 includes a hollow needle 2 having a sharpened distal tip 4 which is movable between a position in which the needle is located within a housing 10 and a patient penetrating position in which the tip 4 extends beyond the distal end of a catheter 28. The catheter 28 and the catheter hub 26 form a catheter assembly which is supported on a catheter hub support 20. The catheter hub support 20 is a one-piece moulding and includes gaskets 30 and 32. Gasket 30 wipes the outside of the needle 2 when the needle 2 is withdrawn from the patient back within the housing 10 to a needle protected position. The function of gasket 32 is to retard the flow of blood between the catheter hub 26 and the catheter hub support 20. <IMAGE></p> |
