Patent ID: 7931622

Claim:
A protector for a cannula having a base and a tip, comprising: an elongate tube having a length to enable it to fit about said cannula and extend from the base of said cannula to beyond the tip of said cannula, said cannula having an outer diameter surface, said tube having an inner diameter surface not in contact with the outer diameter surface of said cannula when fitted about said cannula, said tube including at least three protrusions formed at a given section of said tube with each of said protrusions extending inwardly toward the center of said tube, wherein said protrusions each are dimensioned inwardly toward the center of said tube to come into contact with the outer diameter surface of said cannula when said tube is fitted about said cannula so that said tube is held in place relative to said cannula by friction contact between said protrusions and the outer diameter surface of said cannula, wherein one of said protrusions is positioned at said tube directly opposed to, and below and above respective ones of the other two protrusions to provide a slight bend at said given section to enhance the friction contact with said cannula when said tube is fitted about said cannula, said tube separable from said cannula when a predetermined force is applied to remove said tube from said cannula.
