Abstract
The disclosed invention provides a telescoping tip protector for reducing the risk of needle sticks in used catheter introducers. The pair of telescoping members are adapted such that they telescope from a housing which is gripped by the user with one of the telescoping members locking in a position extending from the housing and the second member locks in a position extending from the first member. The second member carries thereon a tip protecting portion which surrounds the cannula tip and prevents the inadvertent jabbing, piercing or sticking of the needle into a person after the use of the introducer and engagement of the protector.
