Abstract
An indwelling needle assembly for introducing a catheter into a vascular system is disclosed. The indwelling needle assembly is provided with: a needle capable of being slidably fitted in the catheter and insertable into the vascular system; a base body fixed to a proximal end of the needle; a first sleeve slidably fitted around the base body, which is movable between a first position to expose a distal end of the needle and a second position to conceal the distal end of the needle; an elastic body intervening between the base body and the first sleeve so as to urge the first sleeve toward the second position; a second sleeve telescopically fitted to the first sleeve, which includes a latching device configured to hold the first sleeve at the second position; a cover fixed to the base body, which is so dimensioned as to house the first sleeve and the second sleeve when the first sleeve is at the first position; and a lock configured to releasably hold the first sleeve at the first position.
