Embodiment Construction

[0023] Figure 1 generally shows a preferred embodiment of the medical dispensing device of the present invention in an exploded view. The syringe 10 has an elongated cylindrical hollow body 12 with an outwardly extending flange 14 at one end as a finger grip. An elastic head 18 is attached at one end of the plunger 16 . The resilient head 18 provides a sliding and sealing engagement with the inner surface of the body 12 . At the front end of the body 12 is arranged a cylindrical housing 20 having a circumferential groove 22 for placing an O-ring 24 for watertight sealing. Housing 20 has an inwardly and upwardly extending slot 26 , a central bore 28 (as seen in FIG. 2 ), and bores 30 and 32 adjacent central bore 28 .

[0024] A hydrophobic membrane 34 is located in a slot 35 (see FIG. 3 ) on the side of the housing 20 facing the chamber 40 and is associated with a gasket 36 and a duckbill valve 38 to provide passage of gaseous substances from the body 12. Chamber 40 has one-...

Abstract

A medical delivery device comprising an elongate body having a plunger slidably and sealingly engaged to form a cavity to receive fluid materials and a first outlet disposed at an end of said body and has a male luer end portion and a valve assembly is disposed within the first outlet. The valve assembly has a valve means movable between an open position and a closed position and biasing means for biasing the valve means to a closed position. Actuating means are disposed within the male luer end portion and coupled to the valve means such that the valve means is movable to an open position when a female luer end portion of a medical accessory is coupled with the male luer end portion. A second outlet is disposed at the same end as the first outlet for controlling the exchange of gases from the environment to said cavity under the action of the plunger. Lastly, a third outlet is disposed at the same end as the first outlet for controlling the exchange of gases from the cavity to the environment under the action of the plunger.

Description

technical field [0001] The present invention relates to medical drug delivery devices, such as syringes and catheters, for dispensing medical or biological fluids by injection or otherwise. Background technique [0002] Health professionals are concerned with the safe handling of biological substances and pharmaceuticals. Syringes are commonly used medical drug delivery devices, but the use of these commonly used devices presents hazards to both health professionals and patients. Although there have been many developments in recent years, there are still considerable dangers. [0003] When a syringe is filled with a biological fluid or medicine, it is often necessary to remove any gaseous material remaining in the body of the syringe prior to administering the injection to a patient. The reason for this is that injecting air or gas into a patient can be fatal, as the air bubbles will form an embolism in the patient, which can lead to potentially serious and potentially fat...
