An anti-shock system for a catheter line inserted in a patients body. The system includes a spring structure, a base and cover forming a housing with a catheter line entry port and exit port, the spring structure disposed within the housing. A first portion of a catheter line is positioned within the housing, with a distal end portion extending out the exit port, and a body entrance portion extending from the entry port. The spring structure is operatively coupled to a loop of the line and configured to absorb a pulling force exerted on the distal end by a spring action on the loop, without transmitting the pulling force directly to the body entrance portion of the catheter line and thereby prevent undesired migration of the catheter line within the patients body.
