Abstract
A retentive catheter having a cannula tube through which medications may be injected into a patient. A mandrin may be left in the retentive catheter during the injection. The medication is injected through an injection port and flows through a fluid channel between the mandrin and the cannula tube and is discharged from the cannula tube through a valve. The valve may be of the nonreturn type. The mandril tip prevents blood components from entering into the cannula tube. The protection against contamination is increased because the mandrin need not be removed from a proposed injection.
