Abstract
A guard for a cannula is characterized by an outer tubular sheath slidably disposed about the cannula. The tubular sheath includes first engagement tabs to engage the cannula and facilitate insertion of the cannula into a patient. Simultaneously with removal of the cannula from the patient, the cannula and specifically its distal end may be slidably withdrawn into the outer sheath. Second engagement tabs permit permanent retention of the distal end of the cannula within the outer sheath. The first engagement tabs are preferably demountable from the sheath to facilitate ease of disposal of the used components.
