  • a plunger is required to activatethe syrin ge assembly by forcing the stopper downward into the syringe barrel and the liquid within the barrel into the needle for injection purposes.
  • a device which will assist in protecting the needle during handling, shipping and storage from the danger of damage or loss of sterility and which also may function as a shield for the needle and hub when it is attached to a syringe barrel and finally which will act as a plunger for the syringe assembly itself when an injection is to be made would be an extremely valuable and advantageous article in the art. This is particularly true when efficiency of operation, manufacturing, shipping and handling costs are considered. Furthermore, it would also be advantageous if the device which acts as a package, shield and plunger could be manufactured as a multimember unit so that it may function as both a shield and a plunger simultaneously. This would enable the user to protect the needle from exterior contact up until immediately prior to use.

  • the device envisioned would be adaptable for use with syringe barrels well known and in use in the market today.
  • the principal objectives of this invention are to provide a self-contained packaged needle assembly wherein the shielding means functions as a package in assisting in protecting the aseptic condition of a needle contained within, protects the needle simultaneously from possible damage, will function-as a shield for the needle when the needle and its hub is attachedto a syringe adapted to receive it prior to use and which is removable from the needle so that it may be used as a plunger for the completed syringe assembly by means of its attachment to the stopper contained within the syringe barrel so that the entire assembly may be utilized in injecting a fluid into a patients system.
  • a multimember shield means is envisioned whereby when one portion thereof is removed to act as a plunger, another portion of the shield means will remain in protective shielding position over the needle and attached to the hub so that the needle may be completely protected even after the syringe assembly including plunger portion is connected up to and until immediately prior to use.
  • the shield means envisioned is rigid and lightweight in construction, economical to produce, compact and efficient to use so that it may be easily manufactured, shipped, handled and stored until its use is desired.
  • the selfcontained packaged needle assembly including the novel shield means is naturally manufactured so that it is adaptable for use with common types of predetermined unit dose syringe barrels readily available and common in the art.
  • a self-contained packaged needle assembly is provided for connection to a syringe to form a completed syringe assembly.

  • FIGS. 2, 4, 5 and 6 One embodiment of the invention is depicted in FIGS. 2, 4, 5 and 6 and may be described as a self-contained packaged needle assembly including a needle 21 mounted within an opening in a hub 22 so that there is a continuous passageway from the top of hub 22 through to the tip of needle 21. Any common type of bonding means, is employed for this interengagement such as an epoxy bond.
  • a needle 21 and hub 22 are housed within tubular member 23 which may be formed of any common type of rigid plastic material.
  • a closure 24 seals the upper end of hub 22 and member 23 so as to form a completed sealed self-contained packaged needle assembly 2!).
  • Closure 24 may also be of any common type of material to form the seal, for example, a heat sealed piece of paper has been found to perform adequately. Naturally, other bonding means will also work satisfactorily. Closure 24 is sealed to the upper peripheral lip 25 of member 23 and if desirable in addition to the upper peripheral lip 26 of hub 22. The needle 21 and hub 22 would then be sealed within the package and then resterilized to insure that it will be contained in an aseptic condition.
  • hub 22 and needle 21 are fixed in position within member 23 to prevent movement thereof within the package and possible damage to the needle or hub or possibly the piercing of member 23 by needle 21.
  • This is principally accomplished by means of longitudinal internally spaced ribs 27 which are interspaced between corresponding ribs 28 on the lower portion of hub 22.
  • hub 22 is relatively rigidly positioned within member 23.
  • Longitudinal ribs 27 also assist in preventing the bending or displacement of needle 21.
  • An internal shoulder 29 formed by surfaces of member 23 near its upper end form a resting surface for peripheral lip 26 of hub 22. This interengagement between shoulder 29 and lip 26 serves two functions.
  • a tubular extension 30 which has a threaded outer surface 31 the purpose ofwhich will be discussed below.
  • FIG. 3 displays a common type of syringe barrel which is adapted to be connected to the needle and hub shown for the purposes of example in this disclosure.
  • the principal of the self-contained packaged needle assembly of this invention is readily adaptable to many other types of well known syringe assemblies.
  • FIG. 3 it can be seen in FIG. 3 that it is comprised of a cylindrical or tubular barrel 32 having an upper open flanged end 33 and a lower tubular extension 34 adapted to receive thereon a particular size and shapehub.
  • a passageway 35 exposes the interior of barrel 32 with the exterior of the syringe 36 at its lower end.
  • a stopper 37 is positioned within barrel 32 at a predetermined location so as to insure that a predetermined dose of fluid 38 is located in barrel 32 between stopper 37 and the lower end 39 of syringe barrel 32.
  • a cap 40 is positioned over the lower end 34 of syringe barrel 32 so as to be in tight frictional engagement with extension 34 and normally seal the lower end of passageway 35.
  • cap 40 may be constructed of a rubber material which may be removed from extension 34 when it is desirable to attach syringe barrel 32 to a needle and hub assembly.
  • the syringe barrel would have to be inverted from the position shown to one with extension 34 vertically above barrel portion 32 prior to removal of cap'40 in order to prevent loss of fluid through passageway 35.
  • Stopper'37 may also be constructed of a rubber material as well as other known materials and'contains a threaded central recess 41' extending from the stopper upper surface into its central portion.
  • syringe barrel 32 is constructed of a glass material or any other type of materials utilized in the art.
  • FIGS. 2, and 6 A discussion of FIGS. 2, and 6 will demonstrate how this particular embodiment of the invention functions.
  • closure 24 may be peeled off and removed from member 23 so as to permit access to hub 22 and break the seal thereby ending the sterile interior condition of the package 20.
  • needle 21 is still well protected by member 23 and is in a relatively aseptic condition.
  • Rubber cap 40 is then removed from extension 34 of syringe barrel 36 which has been inverted and extension 34 is positioned within hub 22 to arrive at the position of the syringe assembly shown in FIG. 5. Under these conditions, you will note that member 23 still forms a shield for needle 21 and hub 22 to protect them from damage and also to protect the aseptic condition of needle 21.
  • member 23 is removed from its shielding position and placed within the upper open end of syringe barrel 32 so that threaded outer surface 31 of extension 30 may be interengaged with the threaded inner surface of recess 41' of stopper 37. In this manner, member 23 now forms a plunger for the completed syringe assembly.
  • Needle 21 may be then inserted into the patient and member 23 depressed to inject fluids 38 into the patient. From the above discussed sequence of operations it can be seen how member 23 serves three principal functions. First it provides a packaging means to aid and protect the needle and hub assembly during handling, shipping and storage prior to use, it protects the needle and hub after it has been attached to the syringe but prior to its injection into a patient and it forms a plunger for the completed syringe assembly when it is desired to inject a dose of predetermined amount of fluid into a patient.
  • FIG. 2a A modification of member 23 is illustrated in FIG. 2a.
  • the modified form is designated by the reference numeral 23' and the difference lies in the lower end of the member.
  • Member 23 does not have an extension 30, but merely has a closed lower end 30'.
  • Member 23' may act as plunger without being attached to stopper 37 with end 30' merely contacting the upper surface of stopper 37 or it may merely be used as a shield with a separate plunger utilized with the assembly.
  • FIGS. 79 An alternative embodiment is disclosed in FIGS. 79.
  • similar elements are designated by a subscript a" after the same reference numeral as used in the previously discussed embodiment.
  • the self-contained packaged needle assembly 200 includes a needle 21a affixed to hub 22a.
  • a closure 24a is employed similar to that in the previous embodiment.
  • the principal difference in the embodiment lies in the shield means which together with closure 240 form the package to maintain needle 21a and hub 22a in a sterile condition.
  • the shield means includes an inner member 51 and an outer member 42 both of tubular configuration which are in concentric relationship to one another.
  • the upper portion ofinner member 51 engages hub 22a and fixes hub 22a in position, in particular, to the extent which hub 22a may extend within member 51. This is due principally to the tubular shape of member 51 in contrast to the conical shape of hub 22a where the upper portion of hub 22a is of a wider diameter than the inner diameter of member 51 and the lower portion of hub 22a is of a lesser diameter than the inner diameter ofinner member 51. Further assisting in maintaining hub 22a and needle 21a in fixed position within member 51 are longitudinal ribs 43 which are in spaced relationship around the inner circumference of member 51 and which are interspaced between longitudinal ribs 44 on the outer surface of the lower portion of hub 22a.
  • member 42 which is in complete surrounding relationship to inner member 51 and has an upper portion which further encloses the upper portion of hub 22a within a rigid member, this member 42 also has an upper peripheral lip 45 which serves to form a sealing surface for closure 240 which once again may be of a paper material heat sealed on lip 45.
  • An internal shoulder 46 also serves to form a resting surface for the underside of the upper flanged portion 47 of inner member 51. With closure 24a in position and member 42 in position about inner member 51 this shoulder assists in maintaining inner member 51 in tight engagement with hub 22a.
  • the inherent shape of outer member 42 wherein it has a slightly smaller inner diameter in itsupper portion than its lower portion provides for a tight frictional engagement between outer member 42 and inner member 51 which assists in maintaining their engaging relationship in their upper areas.
  • outer member 42 has a lower tubular extension 48 extending from its lower end which has an outer threaded surface 49 which as will be discussed later serves a similar function to the similar extension of member 23 in the previous embodiment.
  • FIG. 8 when closure 24a is removed as shown in phantom in FIG. 7, a syringe barrel 36a similar to that shown in the previous embodiment may be interengaged by means of africtional engagement within hub 22a in a similar manner as FIG. 8, the previous embodiment.
  • both inner member 51 and outer member 42 serve as a shield for needle 21a and hub 22a to maintain both the aseptic condition of these parts as well as protecting these parts from damage.
  • members 51 and 42 may be constructed of a similar material as that of member 23 in the previously discussed embodiment.
  • double members 51 and 42 afford even more protection to needle 210 than does member 23 afford to needle 21 in FIG. 5.
  • outer member 42 may be removed from inner member Sl'and placed within the upper end of syringe barrel 36a. Threaded surface 49 may then be placed into threaded interengagement with threaded recess 41a of stopper 37a so. that outer member 42 becomes a plunger for the completed syringe assembly.
  • a completed syringe assembly which in addition to having member 42 serve as a packaging means, a shielding means, and a plunger, we also have an additional shielding means 51 so that needle 21a may still be protected when outer member 42 is in position as a plunger.
  • the syringe assembly may be completed at any reasonably desired length of time prior to the time of use and the needle 21a will still be protected, then when the injection is actually desired, inner member 51 may be removed from needle 21a and needle 21a may be inserted into the patient, plunger 42 depressed and the desired dose of fluid 38 may be injected into the patient.
  • FIG. 8a the only difference in structure of the needle assembly, designated as b with the subscript b being added to all like parts as those present in needleassembly 20a, lies in the lower end 48 which has a closed flattened configuration rather than being a threaded extension.
  • This modification is similar in construction and operation to that discussed in regard to lower ends 30 and 30' of the illustrated examples of the initially discussed embodiment.
  • FIG. 8a Also demonstrated in FIG. 8a is the manner in which assembly 20a or 20b may be attached to one of the many other common types of syringes with which it may be utilized.
  • the syringe 52 depicted in FIG. 8a is of glass construction and has a metallic connection piece 53 mounted on its lower end. This metal connecting piece 53 is adapted to be mounted on the exterior of hub 22b as well as the interior in contrast to the previously discussed syringes where extension 34 is mounted only on theinterior of hubs 22 and 22a.
  • connection is facilitated by the wider interior diameter adjacent the upper end of members 42 and 42b which provides clearance for connecting piece 53 to extend between the inner surface of the upper end of members 42 and 42b and the outer surface of hubs 22a and 22b respectively and engage the hub to form the assembled syringe assembly.
  • FIG. I it is demonstrated how one or more combinations of a self-contained packaged needle assembly and a syringe barrel container a particular unit dose may be packaged together compactly in disassembled form within a particular package. It can be easily seen how one, five, ten or many more similar combinations may be packaged within one compact protective package 50.
  • Package 50 may be constructed of a low cost expandedfoam type of rigid material such as expanded molded polystyrene with individual chambers for each particular element and then shipped, handled and stored in this compact arrangement for prolonged periods of time.
  • the rigid type of expanded foam package whether it be polystyrene or not afiords additional protection to the aseptic packaged needle assembly 20 and syringe barrel and dose assembly 36.
