Abstract

This patent describes a medicament injector comprising a cylindrical vial having an open end and a closed end, a resilient plug inserted at least partially through said open end engaging the walls of said vial with a press fit, a cylindrical member having one closed end and a needle extending outwardly from said cylindrical member with a sharpened end point, a thin long fluid passage communicating with said needle and extending inwardly into said cylindrical member with a sharpened inner end terminating within the walls of said cylindrical member, lateral support means between said walls of said cylindrical member and said thin long fluid passage in proximity to said sharpened inner end to maintain said passage essentially concentric with respect to said cylindrical member, cooperating threaded interlocking means on said cylindrical member and said plug, whereby upon interlocking the said plug with the said cylindrical member said vial is first held in an assembled but non-operating position and upon further interlocking of said plug with said cylindrical member said plug is pierced by said elongated fluid passage and said passage communicates with said vial and said plug is locked securely to said cylindrical member to permit aspiration upon withdrawal of said vial to permit expulsion of the contents of said vial upon exertion of pressure on said vial. [US3739780A]

Description

BACKGROUND OF THE INVENTION According to the present invention the fluid passage within the cylindrical member which may be a conventional cannula or a plastic member is laterally supported in proximity with the sharpen inner end to prevent relative lateral movement of the fluid passage with respect to the walls of the cylindrical The lateral support may be so positioned as to provide a stop for the vial stopper whereby when the stopper is bottomed out against the latera further rotation of the vial with respect to the injector results the breaking of the seizure of the sealing rings on the vial stopper with the walls of the This structure prevents the fluid passage from being displaced from a central or concentric relationship with respect to the cylindrical The importanc of maintaining this concentric relationship resides in the fact tha an eccentric relationship can result in the sharpened inner end of the fluid passage engaging the plug in the vial in such a way as to core or remove a rubber chip the which rubber chip can subsequently plug the fluid passage more pass through the fluid passage along with the medicament into the patien In vial it has been recognized by the present inven tor that the rings on the vial stopper tend to take a seizure to th walls of the vial during This condition interferes with the smooth and easy operation of the device at the time of United States Patent discloses a solution to this problem in the form of interlocking teeth on the vial stopper and the end of the thrust The present invention involves a new and altogether different approach to this problem while at the same time providing other advantages hereinafter Still another advantage provided by the present invention is the elimination of the need of a metal In the preferred passage enables the nurse to observe by simple aspiration whether the end of the outwardly extending needle has been inserted in the vein of the As is known to those skilled in the most injectable medication is intended for either intramuscular or intravenous To establish whether the device has been appropriately it is conventional to aspirate and watch for the appearance of blood in the vial or The opaque needle involves the possibility that a substantial amount of blood will be This problem is overcome in the present tion since the presence of blood as evidencing injection in the vein can be immediately detected in the translucent end fluid SUMMARY OF THE INVENTION the present invention comprises a medicament injector comprising a cylindrical vial having an open end and a closed a resilient plug inserted at least partially through said open end engaging the walls of said vial with a press a cylindrical member having one closed end and a needle extending outwardly from said cylindrical member with a sharpened end a thin long fluid passage communicating with said needle and extending inwardly into said cylindrical member with a sharpened inner end terminating within the walls of said cylindrical lateral support means between said walls of said cylindrical member and said thin long fluid passage in proximity to said sharpened inner end to maintain said passage essentially concentric with respect to said cylindrica cooperating threaded interlocking means on said cylindrical member and said whereby upon interlocking the said plug with the said cylindrical member said vial is first held in an assembled but position and upon further interlocking of said vial and said plug is locked securely to said cylindrical member to permit aspiration upon withdrawal of said vial or to permit expulsion of the contents of said vial upon exertion of pressure on said It is an object of the present invention to provide several improvements in the art of medicament More it is an object of the present invention to provide a new means for breaking the seizure of the sealing rings of the vial stopper on the walls of the Still another object of the present invention is to provide novel means for the maintaining of the fluid passage within the barrel of a medicament injector in concentric relationship with respect to the walls of the These and other objects and advantages of this invention will be apparent from the more detailed description which taken in conjunction with the accompanying DESCRIPTION OF PREFERRED EMBODIMENTS Turning to the drawings Figure 1 shows a sectional view of one embodiment of this invention in assembled condition with the vial bottomed out against the lateral In this the seizure is broken by further relative rotational movement of the vial with respect to the Figure 2 shows a sectional view of another embodiment of the injector of the present Figure 3 shows still another embodiment of the invention wherein the inner needle has been replaced by a plastic fluid passage within the Turning to Figure 1 in the vial 10 is provided with a rubber stopper 12 having sealing rings 14 which seal on concentrically disposed The stopper 12 also has a jection 13 thereon having a plurality of male The cylindrical member 22 has a closed end 24 and needle 26 extending outwardly from the cylindrical member with a sharpene end point The cylindrical member 22 is provided with female threads 30 for engagement with threads Around the cylindrical member there is preferably provide barrel 32 which has at its open end external gripping means The cannula 26 has a sharpened end 36 which terminates within the walls of the cylindrical member The cannula is externally supported and held by disk 38 through which the cannula The disk 38 is held around its periphery by the 40 on the inside of cylindrical member The disk 38 may be held by a press glued in place or to the cvlindrical member As has been previously the disk 38 can be disposed within the cylindrical member 22 so that it acts as a stop for the projection although the invention is not limited to this In this the projection 18 when made up with th threads 30 on cylindrical member 22 bottoms out on the disk This prevents the further advance of stopper 12 into the cylindric member As shown in Figures 2 and the needle 26 may have a threade fitting 42 at the upper end which engages the Luer taper boss 44 and the internally threaded Luer skirt 46 whereby the needle is securely held to the cylindrical member The fluid be a plastic member as shown in Figure In this the disk 50 can be formed integrally with the fluid The plastic member 48 in the embodiment the embodiment of Figure 3 is assembled and used in the same manner as the embodiments of Figures 1 and As be apparent to those skilled in the the lateral in proximity to the sharpened end of the fluid passage prevents misalignment of the fluid passage in the cal member 22 both in assembly and subsequent As a the sharpened end 36 is so disposed that it will pierce the diaphragm portion 16 when the threads are made there is coring or shipping of rubber such as might occur if the ed end were to pierce the heavier section of the rubber Having fully described the it is intended that it be limited only by the lawful scope of the appended insufficientOCRQuality
