A needle point barrier includes a resiliently deflectable spring arm, a link arm and a barrier arm. The proximal end of the spring arm is secured near the proximal end of the needle. The link arm has one end hingedly connected to the spring arm and an opposed end hingedly connected to a proximal position on the barrier arm. Distal portions of the barrier arm slidably engage the needle. The needle point barrier can be collapsed into a Z-shaped configuration near the proximal end of the needle. The barrier arm can be urged distally by force applied to the proximal end of the barrier arm. Initial movement of the barrier arm willdeflect the spring arm away from the needle. After sufficient manual movement ofthe barrier arm, the resiliency of the spring arm will urge the barrier arm distally into shielding relationship with the distal end of the needle.
