  • FIGURE 8 is 'a longitudinal central sectional yview ,of the fountain syringe showing one manner of iitting a hypodermic needle thereto and a sealing cap.
  • the iirst half shell consists of a half spheroidal bodyk 1 having a V-like surrounding corrugation 2 (inverted in relation to the second half shell) and thel outer limb of the V extends into a ange like lip 3.
  • a plunger 4 is fixed to the inner face of the half spheroidal body 1 at the centrethereof'and it projects axially therefrom. As shown in FIGURE 4 the plunger has a number of 1ongitudinal grooves '5 therein.
  • the second half shell consists of a half spheroidal body y6having a ange like lip 7.
  • a tubular member 8k is fixed to the outer face of the half spheroidal body 6 at the centre thereof 'and it projects axially therefrom in alignment with the plunger 4.
  • Y 4 l f For one form of use the tubular memberv 8 ⁇ has ano'zzle 9 projecting from the end thereof and for another form' of use it has conventional means for attaching a .hypodermic needle thereto.
  • the needle may be con-r Ths fountain syringe is made of an elasto-plastic material (such las polyethylene) compatible to the medicament it is required to hold.
  • For hypodermic injection it has means'for attaching thereto ⁇ a needle made of some other material.
  • An ejector nozzle may be made as c an integral component or as a separate attachment.
  • this fountain syringe comprises a vessel formed by two half shells jointedv together along their mating edges.
  • One half shell (called herein the first half shell) is deformable bythe application of pressure into the other half shell (called herein the second half shell) and j in the deformed position to be in close contact with the inner surface of the second half shell.
  • the second half shell has a tubular member projecting therefrom at a point of even distance vfrom its edge.
  • the bore of the tubular member is in communication with the fvessel.
  • lIts outer end is formed as an ejector nozzle or is formed to have an ejector nozzle fitted thereto. In either form provision can be made to tit a hypodermic needle thereto.
  • Means are provided to close the outlet of the tubular member.
  • the iirst half shell may have a plunger xed thereto in axial alignment with the bore of the tubular member and adpted to enter said bore on deformation of the firsthalf shell.
  • the vessel is of spheroidal shape formed by two half shells joined together along the major circumference of the vessel and it will be so described herein but without limitation thereto.
  • FIGURE .l is a longitudinal central sectional view of y the fountain syringe incorporating a nozzle on the tubular member and a sealing cap. y
  • FIGURE 2 is a plan view of the vessel shown in FIGURE l.
  • fnectedfto the nozzle 9 or the nozzle may be omitted.
  • the tubular member has a flange like bead 10 projecting from the end and,V a cap -11 is provided with a complementaryv groove 12. The cap is held in sealing position by the bead' 10 engaging the groove 12. It is to be understood'that the invention is not limited to any particular form of sealing means. lt may be 'sealedby a membrane capable of being frac ⁇ - tured or pierced.
  • the two half shells 1 and 6 are'joined and lsealed together at theliange lips 3 and 7 preferably by. fusing and when joined the plunger 4 is entered into or is in .a'position to enter into the tubular member 8.
  • the vessel formed by the two half shells is lled with medicament in any convenient manner and rwith the outlet of the the tubularfmember sealed it is in a vendable form.
  • the tubular ⁇ member 3 is of such length and is made sufficientlyl flexible that when fitted with a needle for a hypoderrnic injection it can be first used as an aspirator by 'simply squeezing ⁇ the tube, and then releasing the squeezing pressure whereupon the tubular member resumes its original shape and a partial vacuum is created therein whereby aspirating action is created.
  • the medicament is displaced by applying such pressure to the iirst lhalf shell ⁇ 1y 'that it deforms into the second half shell 6.
  • TheA corrugation 2k per-mits and facilitates completev in-' version of the iirst halfshell 1 commencing from the outer perimeter of the body and when deformation is complete the inner face of -the body 1 is in close contact with the inner -face'of the body 6f
  • the medicament is thus discharged ⁇ from they vessel and as the first half shell remains in the deformed position there is no tendency to draw back thel discharged medicament.
  • the plunger 4 is only required to displace medicament in the tubular member 8 in an ejec-tng operation.
  • the nozzleV 9 is made' integral with the tubular membery and it can be made of an elastoplastic material whichl is so pliable that it can be inserted 3 into a small open passage in a patient without injuring the Wall of the passage.
  • tubular member 8a has diametric extensions 13 throughout its length and these extensions have internal slots 14 in communication with the bore of the tubular member.
  • the plunger t4 to be used in this tubular member does not require the longitudinal grooves 5.
  • the cap lila can be secured in the same manner as the cap 11.
  • the needle can be secured in the nozzle 9 in a moulding or fitting operation.
  • a fountain syringe comprising a vessel made of elastoplastic material, said vessel including first and second half shells joined together along their mating edges, a tubular member projecting from the second half shell at a point of even distance from its edge and having a central bore in communication with said vessel, means to close the outlet of the tubular member from the bore, the tiirst half shell having a V-Shaped circumferential groove adjacent the joined edges of said half shells and opening inwardly toward the second half shell, the outer wall of the groove extending into a iiange-like lip, said groove permitting the irst half shell to be doformed by the application of pressure thereon into the second half shell and into close contact with the inner surface of the second half shell in its deformed position.
  • a fountain syringe comprising a vessel of spheroidal shape, made of elastoplastic material, said vessel including first and second half shells each having a iiange-like lip along its major circumference, said first half shell having a V-shaped groove adjacent said lip and opening inwardly toward the second half shell, the outer wall of the groove extending into and forming its flange-like lip, said two half shells being joined together at the position of said flange-like lips, said V-shaped groove permitting the -iirst half shell to be deformed by the application of pressure into the second half shell and into close contact with the inner surface of the second half shell in the deformed position, a tubular member projecting from the second half ⁇ shell at a point of even distance from its circumference, and having a central bore in communication with said vessel, and means to close the outlet from the bore.
  • a fountain syringe according to claim 2 having an ejector nozzle on the outer end of said tubular member.
  • a fountain syringe according to claim 2 having means for fixing a hypodermic needle to said tubular member.
  • a fountain syringe according'to claim 2 in which the first half shell has a plunger iixed thereto in axial alignment with the bore of said tubular member, said plunger being adapted to enter said bore on deformation of said first half shell.
  • a fountain syringe comprising a vessel of spheroidal shape, made of elastoplastic material, said vessel including Afirst and second half shells, each having a flange-like lip along its major circumference, said first half shell having a yV-shaped groove adjacent said lip and opening inwardly toward the second half shell, the outer w'all of the groove extending into and forming its flange-like lip, said two half shells being joined together at the position of said flange-like lips, said V-shaped groove permitting v the first half shell to be deformed by lthe application of pressure into the second half shell and into close contact with the inner surface of the second half shell in the deformed position, a tubular member projecting from the second half shell at a point of even distance from its edge and having a central bore in communication with said vessel, means to close the outlet from the bore and means for ⁇ fixing a hypodermic needle to said tubular member,
