ABSTRACT:
A hypodermic syringe is disclosed which facilitates both the transportation of a fluid specimen therein and the ready accessibility of the specimen in the syringe. The hypodermic syringe is provided with a port in the syringe barrel proximate the needle neck of the barrel. Location of the port in this area facilitates the introduction of sampling instruments into the interior chamber of the syringe. A fluid-tight cap is provided for the port. A boss is also provided spaced inwardly along the exterior of the barrel of the syringe near the plunger opening of the syringe, to thereby incline the syringe to promote pooling of specimen fluids in the area of the port. A rigid protective cover for a hypodermic needle mounted on the needle neck of the syringe is removably received on the barrel of the syringe, and is spaced radially from the neck, and surrounds the hypodermic needle to protect the needle during transport.
A series of spaced detents extend longitudinally along the elongated body portion of the syringe plunger. A resilient member carried on the barrel of the syringe adjacent the plunger opening is biased to engage the detents of the body portion of the plunger, whereby the resilient member permits withdrawing movement of the plunger and prevents reinserting movement, such as might be caused by accident during transport of a specimen containing syringe.
