CATHETER MOVEMENT CONTROL DEVICE AND METHOD

摘要

A catheter movement control device is presented having therein a resilient biasing member and a tube gripper which mount on a catheter tube. The biasing member and tube gripper are contained within a housing having a shoulder proximate the catheter tube. As the catheter tube is free to move in a forward direction through the housing, upon attempted rearward movement the biasing member engages the tube gripper causing it to pivot against a shoulder within the housing. Upon pivoting the tube gripper tightly engages the catheter tube preventing any further rearward movement of the catheter tube.
