Definitions

  • the present invention relates to a syringe type device for administrating medicaments such as liquid baby aspirin to children and more specifically to novel features in such devices which provide a greater acceptance with children and thus may be termed CHILD FRIENDLY SYRINGE. BACKGROUND OF THE INVENTION
  • Atypical syringe assembly for injecting medicaments of various types includes an outer hollow generally cylindrically barrel made of glass, a plunger usually made of rubber, of a diameter to snugly engage the inner peripheral side wall of the barrel and an elongated plunger rod connected to the plunger for reciprocating the plunger axially in the barrel to draw liquid medicament into the syringe through a needle attached to the discharge end of the barrel.
  • the syringe assemblies employ a sharp needle for medicaments to be injected into the vein and in other instances the needle comprises a blunt cannula. Even though these instruments are generally effective for the purposes intended, it has been found that children tend to be fearful of syringes having this appearance because they associate use of the syringe with pain associated with use to administer products by skin penetration.
  • the syringe assembly particularly adapted for administering oral dosages of medicaments such as liquid Motrin® or the like to children and which by its appearance and operation may be characterized as a child friendly syringe because it does not invoke fear in the children when they see it.
  • the syringe of the present invention is characterized by novel features of construction and arrangement facilitating easy and economical manufacture and molding of the parts and characterized by a novel design which is not threatening to children and thus may be characterized as a child friendly syringe which can be operated easily and quickly to fill with a predetermined dosage and to dispense and reuse.
  • Figure 1 is an exploded perspective view of the components of a child friendly syringe assembly in accordance with the present invention
  • Figure 2A is a side elevational view of the syringe assembly in the assembled relation
  • Figure 2B is a transverse sectional view of the syringe assembly taken on lines 2B-2B of Fig. 2A;
  • Figure 2C is a bottom plane view of the syringe assembly
  • Figure 2D is an enlarged view of the portion circled in broken lines
  • Figure 3A is a side elevational view showing the application of the child friendly syringe assembly to a medicament container in position to withdraw the medicament contents in the container;
  • Figure 3B is a transverse cross-sectional view showing the child friendly syringe assembly in position in the neck of the container in a first stage for withdrawing the medicament product from the container;
  • Figure 4A is a transverse sectional view similar to Fig. 3B showing the barrel of the syringe barrel in a retracted position to withdraw medicament product from the container;
  • Figure 4B is an enlarged sectional view of the area circled by broken lines identified "4B" in Fig. 4A;
  • Figure 5A is a transverse sectional view with the syringe assembly removed from the insert;
  • Figure 5B is an enlarged sectional view showing the insert and starburst fitting with the syringe assembly removed and sealing flow of liquid product from the container;
  • Figure 6A is a transverse sectional view of the syringe similar to Figure 5A after filing with a predetermined dosage;
  • Figure 6B is an enlarged sectional view of the portion circled in broken lines in Figure 6A labeled 6B;
  • Figure 7A is a transverse sectional view of the syringe assembly showing the plunger in its rearmost outer portion in the barrel;
  • Figure 7B is an enlarged view of the portion circled in broken lines in Figure 7A;
  • Figure 8A and 8B is an enlarged sectional view showing a modified plunger design in two (2) portions; and Figure 9 is a view showing the diametrical relationship of elements of the plunger and barrel to locate and seat the plunger in its rearmost outer portion.
  • the syringe assembly as illustrated comprises an elongated generally cylindrical hollow tubular barrel 12 which is outwardly flared at its outer end as at 14 to provide a finger grip portion.
  • the outer end of the barrel 12 is rounded or spherical shaped as at 16 and terminates in a short hollow cylindrical projection 18 defining a discharge opening 20.
  • the syringe assembly further includes an elongated plunger 22 having a spherical tip 24 which seats in the barrel 12 and conforms generally to the shape of the barrel 12 to snugly seat in the bottom of the barrel 12 in the manner illustrated in Fig. 2B.
  • the plunger also has an outwardly flared upper end as at 26 to define a circumferentially extending finger grip portion 26.
  • the syringe assembly 10 seats at its tip portion in an insert generally designated by the numeral 30 which fits in the discharge opening 32 in the neck of a container C.
  • the insert 30 has a generally cylindrical outer wall 32 having a radially outwardly, circumferentially extending flange 34 which seats on the axial end face 36 of the container in the manner shown in Fig. 4B.
  • the outer wall 32 has a circumferentially extending sealing lip 40 located axially downwardly from the end flange 34 which snugly engages the interior wall 44 of the container C to function as a seal in this area.
  • a lower sealing flange 46 projects radially outwardly from the lower terminal edge of the outer wall 32 to seal with the interior wall 44 of the container C in the manner shown and prevent medicament product from migrating into the open region between the outer wall 32 and the interior neck finish during a syringe filling cycle in the manner described below.
  • the insert 30 also has an interior wall 44 co-extensive with and spaced from the outer wall 32 to permit radial flexing when the syringe is seated in the insert 30 to be filled in the manner shown in Figs.4A and 4B.
  • the interior wall 44 has a beveled upper face as at 52 to conform to the somewhat tapered shape of the barrel 12 to provide a snug seating arrangement when the barrel 12 is pressed into the insert 30 for a filling cycle.
  • the insert 30 has an upwardly flared bottom wall 54 which has a central opening 56.
  • Formed integrally with the opening 56 are a plurality of triangularly shaped leaves 60 in a starburst pattern which can be deflected outwardly by the tip of the barrel 12 in the manner shown in Fig. 4B to permit filling of the syringe by simply withdrawing the plunger in the manner shown in Figs. 4A and 4B.
  • the syringe plunger 22 is normally fully seated in the barrel 12 in the manner shown in Fig. 3B.
  • the barrel 12 is normally seated in the insert 30 in the manner shown in Fig. 3A.
  • a sealed medicament bottle C containing the medicament to be dispensed is then readied for the syringe by removing the cap.
  • the syringe assembly is then positioned over the open end of the bottle and the insert 30 is then moved axially into the open end until the flange 34 seats on the axial end face of the bottle C.
  • the triangularly-shaped leaves 60 are in a spread condition so that when the plunger 22 is drawn rearwardly by the user, medicament can flow into the syringe barrel 12 in the manner indicated by the arrows in Fig. 4B.
  • the user can then withdraw the barrel 12 axially whereby the leaves 60 automatically return to their closed position providing a sufficient seal to protect the contents of the container C.
  • the user can then administer the pre-measured dose of the medicament to a child patient.
  • the barrel 12 as illustrated has a generally cylindrical elongated body portion 12Aof a uniform internal diameter D extending between the nose 16 at one end and the outwardly flared upper portion 14.
  • the nose 16 as illustrated has a slightly inwardly flared spherical tip 16 and merges with body portion 12a in a somewhat conical section 12b which tapers
  • the spherical tip 24 of the plunger 22 likewise has a slightly tapered frusto conical section 22bconnecting the spherical tip 24 and the body portion 22a which is also of general uniform diameter for substantially the full length between the spherical tip 24 and flared outer end 26.
  • the tip and tapered connecting portion of the plunger complement the tip and tapered connecting portion of the barrel for full evacuation of product in the syringe.
  • the upper end of the barrel 12 adjacent the flared end 14, is provided with a circumferentially extending ledge 72 and the upper end of the plunger 22 adjacent the flared end 26 is provided with a circumferentially extending ledge 74 for ease and removal of the part during the molding process.
  • the plunger 22 and barrel 12 are preferably made of different materials for good sliding action between the parts when the plunger is activated axially in the barrel for filling and discharge purposes.
  • the barrel is made of polypropylene.
  • the plunger is made of polyethylene. It has been found that similar materials rubbing against one another tend to stick and cause what is commonly referred to as galling.
  • the plunger 22 is provided with a circumferentially extending radially outwardly directed rib 76 adjacent the juncture of the body portion 22A and the tapered transition portion 22B which is preferably of a diameter D1 slightly greater than the internal diameter D2 of the body portion of the barrel 12 to provide a snug but easy sliding fit when the plunger 22 is activated axially in the barrel.
  • the bore 12C of the barrel 12 on either side of a circumferentially extending spherically shaped protrusion 82 on the interior surface of the barrel body portion adjacent its outer end is tapered inwardly at a predetermined angle ⁇ toward the protrusion 82 so that the internal diameter D3 in these regions is slightly greater than the diameter D1 of the rib 76 on the plunger.
  • the protrusion 82 is of a predetermined diameter D3 smaller than the rib diameter D4 to provide a resistance to removal and complete separation of the plunger from the barrel.
  • the rib 76 can be snapped over the protrusion 82 when it is desired to disassemble the parts, for example, to sterilize due to the flexibility afforded by the materials and all thickness of the barrel and plunger.
  • Figs 8A and 9A shown a modified plunger 22 having a pin like projection 90 which extends downwardly from the spherical tip to engage in the collar 18 when the plunger 22 is fully seated in the barrel 12.
