The first sleeve is removably carried by a hub, which also carries the needle. In accordance with this invention an inner sleeve is provided, positioned within the first sleeve and about the point of the needle. The inner sleeve is free of mechanical attachment to the first sleeve so that, upon rotation of the outer sleeve for its removal from the hub, the inner sleeve does not rotate with the first sleeve. Accordingly, the danger of the pointed needle scourint out and retaining bits of plastic from the sleeve is eliminated.</p> |
