Definitions

  • a self-contained disposable syringe including a syringe barrel with an open rear end and a needle mounted on the forward end.
  • the needle has a passage therethrough which communicates with the interior of the barrel.
  • a plunger is positioned within the syringe barrel and is movable with respect to the barrel.
  • a needle shield is normally positioned in sealing engagement with the forward end of the syringe barrel and surrounds the needle so as to protect the needle from damage and loss of sterility.
  • a removable seal on the rear end of the syringe barrel normally provides a compact sealed self-contained disposable syringe in sterile condition and suitable for shipment and storage.
  • the needle shield is adapted for removal from the forward end of the barrel and is adapted for engagement with the rear end of the plunger to form finger gripping means on said plunger to facilitate the movement of the plunger with respect to the barrel when the sealed syringe is open for use.
  • disposable syringes are generally contained in a packaging medium which entails the use of one or more elements to contain and protect the syringe from damage during shipment and handling. Additionally, the packages employed are designed to retain the syringe in a sterile condition during the shipping, handling and storage thereof until it is desired to use the-syringe.
  • Packages of this type tend to be bulky and consequently consume more storage space per unit than is desirable. Furthermore, when the package is opened and the syringe removed there are often portions of the package which have to be removed by fracture or some other means and then discarded.
  • a packaging medium employed to contain each individual syringe or a multiplicity of syringes the cost of providing the packaging contributes significantly to the overall cost of each individual disposable syringe. It is desirable that a disposable syringe be manufactured at as low a cost as possible thereby facilitating the sale of a disposable syringe at a low price.
  • the use of a packaging medium to contain the syringe adds additional and unnecessary bulk to each individual syringe which can significantly detract from valuable storage space in a hospital or other storage area.
  • a syringe which consists of the usual components of plunger, needle, needle shield and barrel and also constitutes its own package which will maintain a sterile interior prior to use as well as protect the frangible portions of the syringe such as the needle from damage.
  • a syringe which may be easily disassembled from its packaging arrangement and assembled into its operating arrangement with a minimum amount of effort and time. This would be advantageous in providing a syringe which is equivalent to the preassembled syringe in package form now on the market where no assembly steps are necessary. Therefore, the syringe which forms its own package should be readily and easily adaptable from its packaged configuration to its assembled configuration in as few steps and as quickly as possible.
  • a syringe including a plunger, needle, needle shield and barrel which in normal assembly forms its own package and will maintain a sterile interior prior to use. No additional packaging components are required with the exception of a paper or plastic cover sealed to the end of the barrel and possibly the shield if desired.
  • the self-contained syringe will maintain the interior portions thereof in a sterile condition during shipping, handling and storage and additionally will protect the frangible portions of the assembly such as the needle.
  • an object of this invention is to provide a selfcontained disposable syringe wherein in the preparation of the syringe for use, the time required for this preparation is minimized since no components need be removed or disassembled and discarded.
  • the shield is adapted to be removed from the needle and assembled to the plunger rod in one motion thereby transforming the package syringe into a syringe ready for immediate use quickly and efiiciently.
  • a self-contained disposable syringe which includes a syringe barrel having an open rear end and a needle mounted on the forward end thereof. Theneedle has a passage therethrough communicating with the interior of the barrel.
  • a plunger is normally positioned within the barrel and is movable with respect to the syringe barrel.
  • a needle shield is normally in sealing engagement with the forward end of the syringe barrel and in surrounding relationship with the needle so as to protect the needle from damage and loss of sterility.
  • Removable sealing means is positioned on the rear end of the syringe barrel thereby normally providing a compact sealed, self-contained disposable syringe in sterile condition and suitable for shipment and storage.
  • the needle shield is adapted for removal from the forward end of the barrel and adapted for engagement with the rear end of the plunger to form finger gripping means on the plunger to facilitate the movement of the plunger with respect to the barrel when the sealed syringe is opened for use.
  • FIG. 1 is a central sectional view of the selfcontaine'd disposable syringe of this invention shown in its normally sealed sterile packaged condition;
  • FIG. 2 is a central sectional view thereof showing the syringe with its components in their unpackaged condition and with the syringe assembled for immediate use.
  • FIG. 1 of the drawing shows the self-contained disposable syringe 20 of the invention in its sterile packaged form.
  • the syringe assembly in package form basically consists of a syringe barrel 21, a needle 22, a plunger 23 and a needle shield 24.
  • both open ends of the package are sealed with separate sealing means.
  • Sealing means 25 covers the end of needle shield 24 distal from syringe barrel 21 and sealing means 26 covers the rear end of syringe barrel 21.
  • Syringe barrel 21 is a conventional type of syringe barrel which is constructed of a plastic material which lends itself readily to disposability.
  • the syringe barrel is hollow and of a general cylindrical configuration and has a reduced forward cylindrical end portion 27. Reduced portion 27 has a bore 28 therethrough which communicates at its forward end with the exterior of the syringe barrel and at the rear end with the interior of syringe barrel 21. It may also be noted that the portion of syringe barrel 21 immediately adjacent the forward reduced portion is tapered into a conical configuration to facilitate flow of fluid into and out of the syringe barrel and also proper engagement with the stopper mounted on the forward portion of plunger 23 as will be discussed in greater detail below.
  • Needle or cannula 22 is a common commercial type of syringe needle metallic in nature and having a bore 29 therethrough.
  • the forward end of cannula or needle 22 has a pointed puncture tip 30 for insertion into a fluid source.
  • the rear end 31 of cannula 22 generally has a blunt configuration and communicates with the interior of the main body portion of barrel 21.
  • Cannula 22 may be retained in position within reduced forward end 27 by any common bonding means such as an epoxy resin.
  • Reduced forward end 27 has a number of spaced longitudinal ribs 34 on its outer surface to provide additional rigidity and strength to end 27.
  • annular skirt 32 Extending from the main portion of barrel 21 is an annular skirt 32 which has the same outer diameter as the main portion of barrel 21 and a larger inner diameter than forward reduced portion 27 of syringe barrel 21. It is not necessary that skirt 32 have the same outer diameter as the main portion of barrel 21. Annular skirt 32 as shown extends at least as far forward as the forward tip of reduced portion 27 and is substantially concentric with reduced portion 27 and needle 22. Skirt 32 does not necessarily have to extend as far forward as the tip of portion 27.
  • the recess 33 formed between the outer surface of reduced portion 27 and skirt 32 forms a reception space for a portion of needle shield 24 as will be discussed in greater detail below.
  • the rear end portion 35 of syringe barrel 21 has a larger inner and outer diameter than the main body portion of barrel 21 and is connected thereto by means of a tapered integral conical shaped portion 36 which is of the same diameter at its rear end as rear portion 35 and has the same diameter at its forward end as the main body portion of barrel 21.
  • the purpose of this larger diameter portion 35 on the syringe barrel 21 is for readily facilitating the engagement of needle shield 24 with plunger 23 as will be discussed in greater detail below.
  • a pair of diametrically opposed finger gripping flanges 37 extend outwardly from syringe barrel 21 intermediate the larger diameter upper portion 35 and the main portion of syringe barrel 21. These flanges facilitate the gripping of the syringe when it is in actual use.
  • Plunger 23 may assume a variety of different configurations with the principal criteria being that it be a rigid member preferably of a low cost material such as plastic and be of a length which permits-it to be located entirely within syringe barrel 21 when the selfcontained disposable syringe is in the sealed packaged condition.
  • a plurality of spaced longitudinal ribs 38 extend almost the entire length of plunger 23 with the exception of its forward end portion. These ribs 38 serve to rigidify plunger 23 and also form an engaging surface for shield 24 when it is connected to plunger 23 to form the finger gripping portion of plunger 23 when the syringe is opened and prepared for use.
  • a retaining lug 55 is on the plunger adjacent the rear end thereof to assist in maintaining shield 24in position on the rear end of plunger 23 during use. Lug 55 engages with the inner surface of the forward portion of the shield in a tight frictional engagement to provide increased retention force to hold the shield in position on the plunger.
  • the forward end portion of plunger 23 is in the form of a small diameter cylindrical projection 38 terminating in a flanged tip 39.
  • the point of engagement between projection 38 and flanged tip 39 forms a shoulder 40 to facilitate engagement and retention of a flexible stopper 41 mounted on the forward end of plunger 23.
  • Stopper 41 may be constructed of any common type of elastomeric material commonly used in the art today such as a flexible rubber or plastic material. Furthermore, alternatively, the stopper may be formed integrally with the plunger as one member. Stopper 41 has a recess 42 interiorly thereof to receive flanged tip 39 as shown in the drawings. In this manner, stopper 41 is mounted to plunger 23 and is moved longitudinally within barrel21 as plunger 23 is moved longitudinally within barrel 21.
  • needle shield 24 which also may be constructed of a common type of plastic material, it will be noted that the main body portion 45 is cylindrical in configuration and has substantially the same inner and outer diameter as a portion of syringe barrel 21. This provides for a substantial uniform diameter intermediate the end portions of the syringe assembly 20 when in its sealed condition. In this sealed condition, needle shield 24 has one end proximal the syringe barrel 21 and one end distal the syringe barrel 21. The distal end 46 has a flange on the circumference of its outer edge to receive.
  • the proximal end 47 has a reduced outer diameter substantially less than the outer diameter of the main body portion 45 of needle shield 24.
  • This reduced end portion 47 of needle shield 24 is substantially cylindrical in configuration.
  • the outer surface of reduced end portion 47 has a pair of annular rings 48 in parallel relationship to one another and projecting therefrom.
  • the resultant outer diameter on reduced portion 47 provided by annular rings 48 and the engagement between the inner diameter of skirt 32 form a tight frictional engagement when reduced end portion 47 is inserted into recess 33 provided between skirt 32 and reduced forward portion 27 of syringe barrel 21.
  • the engagement occurs with sufficient friction so that when the deformation of rings 48 occurs, reduced proximal end 47 will snap into position within the forward end of syringe barrel 21 thereby forming a seal .therebetween thereby preventing contamination of needle 22.
  • sealing means 25 and 26 may be sealed by means 25 and 26 at each end of disposable syringe 20 respectively.
  • the type of material utilized for sealing means 25 and 26 may vary according to the type of sterilization process used. If the disposable syringe 20 is to be gas sterilized, the material utilized for sealing means 25 and 26 would be in the form of a porous paper which is gas permeable and which will maintain sterility after the gas sterilization process. Naturally the gas sterilization process utilized is one commonly known in the art. If other methods of sterilization are to be employed such as by radiation, sealing means 25 and 26 may take the form of an impermeable paper, plastic, paper-foil, laminate or other similar material in which case the syringe would be hermetically sealed and sterilized.
  • sealing means 25 may be eliminated and the main portion of shield 24 including its distal end 46 may be formed of an integral plastic material.
  • the shown design configuration would be changed to facilitate manufacture of shield 24. The reason this may be accomplished will be discussed below when it will be readily seen that there is no necessity that the distal end 46 of needle shield 24 be opened for operation of the syringe.
  • sealing means 25 and 26 are in the form of a gas permeable paper and disposable syringe 20 as shown in FIG. 1 has been gas sterilized and appears in its sealed condition.
  • sealing means 25 and 26 when gas sterilization is employed, a gas permeable plastic material such as nylon may also be utilized.
  • sealing means 25 and 26 takes the form as shown in FIG. I, it may be bonded to the respective ends of syringe assembly 20 by any common means. Furthermore, it is not necessary even for gas sterilization that sealing means 25 be at the distal end 46 of needle shield 24. When the disposable syringe 20 is shown in its sealed and packaged condition as in FIG.
  • a heat mark 51 may be located at the juncture of rim 48 and shoulder 49 so as to be utilized as a tamper-proof indicator thereby providing a readily usable means of determining if the sterility of the interior of disposable syringe 20 may have been affected by previous removal of shield 24.
  • Needle shield 24 performs the usual function of protecting the needle from damage and in addition it protects the sterility of the needle, and as will be discussed in greater detail below provides for an extension to plunger rod 23 permitting it to be used in a normal manner when the syringe is opened and used. It should be kept in mind that the plunger prior to use is preferably enclosed completely within syringe barrel 21 thus allowing sealing means 26 to be positioned over the rear end of syringe barrel 21 to assist in providing sterility protection and if so desired, a hermetic seal.
  • FIG. 2 illustrates the self-contained disposable syringe in unpackaged condition and ready for immediate use. All that need be done to accomplish this positioning is to withdraw needle shield 24 from the forward end of syringe barrel 21 by supplying suflicient force to overcome the frictional engagement between proximal end 47 and the forward end of syringe barrel 21. Needle shield 24 may then be inverted and projected onto the rear end portion of plunger 23. This exposes needle 22 for projection into whatever medium is desired.
  • the unpackaging of syringe may be accomplished in a one-step operation, that is by merely removing needle shield 24 from its sealing position at the forward end of syringe barrel 21 and by removing sealing means 26 and engaging proximal end 47 of needle shield 24 with the rear end of plunger 23.
  • the syringe is then ready for operation with finger gripping means being provided on the main body portion 45 of needle shield 24 and flanges 37 on syringe barrel 21.
  • finger gripping means being provided on the main body portion 45 of needle shield 24 and flanges 37 on syringe barrel 21.
  • body portion 45 of needle shield 24 there are a plurality of spaced longitudinal ribs 52 on the outer circumference of body portion 45 of needle shield 25.
  • sealing means 26 may first be removed before shield 24 is positioned on plunger 23 rather than just merely punctured.
  • a tab 53 as shown in FIG. 1 may be provided to facilitate the removal of sealing means 26 from the rear surface of the syringe barrel 21 to which it is fastened by common means such as an adhesive.
  • the engagement between the proximal end 47 of needle shield 24 and the rear end of plunger 23 is by means of a frictional engagement between the inner surface of proximal reduced end 47 and the outer surface of ribs 38 on plunger 23.
  • the frictional engagement may be of a tight nature due to the deformability of the plastic members so that a snap-on result may once again be achieved thereby providing a positive engagement so that when needle shield 24 is moved longitudinally plunger 23 will simultaneously be moved longitudinally and there will be little or no danger of disengagement therebetween.
  • the rear portion 35 of syringe barrel 21 is of an expanded inner and outer diameter.
  • syringe 20 is in a ready to use position whereby the puncture end of needle 22 may then be inserted into a fluid source and connected needle shield 24 and plunger 23 may be withdrawn thereby withdrawing connected stopper 41 and drawing fluid into recess 44 of syringe 21 through needle 22 until the desired amount has been collected. Needle 22 may then be withdrawn from the source of the fluid and combined needle shield 24 and plunger 23 may be projected forward thereby projecting stopper 41 forward and ejecting the fluid through needle 22 into its ultimate reception area.
  • the tapered forward end of the main body portion of syringe barrel 2] facilitates the flow of fluid in both directions through needle 22 as stopper 41 is moved along the interior of syringe barrel 21.
  • stopper 41 may assume a configuration which approximates the configuration of the tapered forward portion of barrel 21 to assist in projecting the greatest possible amount of fluid from within syringe barrel 21.
  • the sealing engagement between annular projections 43 on stopper 41 and the inner surface of barrel 21 prevents passage of fluid or air between the forward and rear ends of stopper 41.
  • the syringe Since the syringe is disposable, once it has been used it may be then discarded. All of the components are of a low cost economical material so that disposability may be readily attained due to the low cost of the syringe.
  • the resultant self-contained disposable syringe has a number of significant features which are obvious advantages over the known art. Among these are the fact that a minimum number of components are involved since no parts are used as a package with the exception of sealing means where necessa ry such as sealing means 25 and 26 as shown in FIG. 1. This allows the syringe package combination to be manufactured for a cost approximately equal to that of the usual disposable syringe without its package thereby saving the extra cost involved in providing a packaging means for the disposable syringe. This also facilitates the provision of a syringe having a minimum amount of bulk since there are no excess parts and thereby permits the storage of a greater number of units per given storage area.
  • the preparation prior to use of this syringe is minimized since no components need be removed and discarded.
  • the shield can be removed from the needle and assembled to the plunger rod in one motion.
  • a self-contained disposable syringe comprising:
  • a hollow syringe barrel having a substantially cylindrical main body portion and a rear end portion having an open rear end and a larger diameter than that of said main body portion, and needle mounting means at the forward end of the barrel;
