Abstract

A needle point protection sheath comprises a protector tube having a bore for receiving a hollow needle plus a needle hub within the bore. The protector tube has closure cap at one end thereof and has a retention member at the other end to engage an end of the hub, to prevent the hub from passing out of the other tube end. The cap may carry a sleeve having a needle-pierceable wall at its inner end, or a mass of resilient material which is capable of being penetrated by the needle as the cap is closed, to seal the needle tip and thus prevent the spilling of blood residue when a blood collection needle is being enclosed for protection.
