Definitions

  • the present invent-ion has for its objects an ampulla incorporating an injection syringe, so that the liquid to be injected contained inside the ampulla, may be injected directly without any further aid, according to an intramuscular or to a subcutaneous procedure, while remaining in conformity with the strictest prescriptions of practitioners who require that the introduction of the hollow needle may be performed under dry conditions, the actual injection of liquid being performed no'longer simultaneously with said introduction, but immediately afterwards.
  • the body of the ampulla which is advantageously made of synthetic material and contains the liquid to be injected, includes a hollow guiding cylinder and an extension rigidly connected with said guiding cylinder, which latter carries slidingly a piston provided with a central bore inside which is slidingly carried in its turn a rod carrying a hollow needle, while a sleeve in the shape of a cartridge, is adapted to slide over the guiding cylinder.
  • FIGS. 1, 2 and 3 are vertical cross-sections of a first embodiment of the ampulla for different positions of the injection syringe incorporated with the ampulla.
  • FIG. 4 is, on a slightly larger scale, a vertical crosssection of the safety means provided for the syringe when it is in the position illustrated in FIG. 2.
  • FIG. 5 illustrates an annular spring forming part of said safety system.
  • FIGS. 6 and 7 are vertical cross-sections of ampullae according to a second and a third embodiment respectively.
  • FIG. 8 shows any of the ampullae described, which ampullae are outwardly all similar, said FIG. 8 showing the ampulla in true size in its closed condition.
  • FIG. 9 is .a vertical cross-section of the ampulla ready for injection, in accordance with a fourth embodiment.
  • FIG. .10 is a cross-section under similar conditions of the rear portion of the ampulla shown in FIG. 9 after the injection procedure has begun.
  • the ampulla according to FIGS. 1, 2 and 3 includes a metal sleeve or socket 10 in the shape of a cartridge, of which the bottom Illa is very thick, whereas the cylindrical section 1% of said socket is thinner.
  • the connection between said bottom :and said cylindrical section forms a rfrusto -conical shoulder 10c.
  • the metal sleeve 10 is slidingly fitted over a guiding member 11a constituted by a hollow cylinder forming part of the actual body of the ampulla and made of synthetic material such as polyethylene for instance, said body 11 being provided at 11b with an extension of the hollow cylinder 11a and enclosing a chamber which tapers towards the free end of said extension.
  • the restricted opening formed at the narrow end of the chamber in the extension 11b serves as a guide for the hollow needle, as described hereinafter with further detail.
  • a tapped cap 12 provided at its outer periphery with longitudinal grooves, while its edge has a slightly reduced diameter, so that it may engage the inside the protecting sleeve 10 when the cap 12 is screwed home.
  • the bottom of said tapped cap 12 which is also made of a suitable synthetic material is provided with an inner central projection 12a engaging, when the cap 12 is thus positioned, the outwardly flaring opening at the outer end of the extension 11b, so that said central projection may close last-mentioned opening fluidtightly.
  • the access into the hollow needle 15 is obtained through a port 14w provided in the corresponding extreme section of the rod 14, while the wall of the hollow needle 15 is interrupted in registry with said port 14a.
  • the hollow needle 15 When the ampulla is inoperative, the hollow needle 15 lies fully inside the body of the ampulla 11. At the same time, the port 1 m provided in the rod 14 for access into the hollow needle, is located inside the bore-in the piston 13, so that it is impossible for the injection liquid to pass into said needle out of the chamber containing said liquid.
  • the ueedle-carryingrod 14 engages through its end opposed to the hollow needle a small pedestal 16 carried by the bottom of the protecting socket 10 and it is secured to said pedestal by a transverse pin 17. Said pedestal 16 is engagedby one end of the compression spring 18, of whichthe other end engages a disc-shaped stop 19.
  • the needle-carrying rod 14 is provided furthermore in its central section with a peripheral groove 14b inside which an annular spring 20 is engaged as long as the ampulla is inoperative, said annular spring illustrated separately in FIG. including for its engagement in said groove 14b two arms 2.0a which are folded and bent into registry with each other.
  • a safety member 21 (FIG. 4) in the shape of a disc holding said spring 20 in position, said safety disc being provided with elastic arms 21a directly downwardly and bent so as to form safety noses 21b.
  • said noses 21b extend beyond the outer edge of the cylindrical section 11a of the body of the ampula 11, which prevents any outward projection of the piston under the action of the spring 18 acting through the stop 19 and disc 21.
  • the front end of the ampulla is urged against the point of the patients body at which the injection is to be performed, and a pressure is exerted in an axial direction on the protecting sleeve 10. Consequently, said sleeve is urged forwardly over the cylindrical section 11a of the ampulla body 11, while the spring 18 is simultaneously compressed.
  • the needle-carrying rod 14 is urged outwardly together with the hollow needle 15.
  • the annular spring 20 opposes first said shifting, since said spring engages the peripheral groove 14b on the rod 14.
  • said annular spring is suddenly released with reference to the peripheral groove 14b, so that the entire pressure exerted by hand on the protecting sleeve 1t? and which is reinforced by the energy of the compression spring 18 acting through the discs 19 and 21, is
  • the point of the patients body which is to receive the injection is subjected suddenly to the action of the hollow needle 15.
  • the narrow opening in the extension 11b of the ampulla body serves at such a moment as a guide for the hollow needle 15.
  • the port 14a providing an access into the hollow needle, is urged suddenly beyond the bore in the piston 13; the port thus uncovered allows a passage into the needle of the injection liquid contained in the inner chamber of the ampulla body 11.
  • the pressure applied on the protecting sleeve 10 continues then being exerted against the action of the compression spring '18 until the a-mpulla assumes the position illustrated in FIG.
  • the hollow needle engages the body of the patient who is to receive the injection down to the medically defined depth.
  • the maximum depth of injection is limited by the fact that the needle-carrying rod 14 engages through its front end a stop constituted by the inner frusto-conical wall of the extension 11b of the ampulla body 11, as clearly shown in FIG. 3.
  • the injection procedure is at an end and, furthermore, as described hereinabove, the actual injection can be executed only when the hollow needle has engaged the patients body down to the maximum depth provided
  • the compression spring 13 urges the small pedeStal 16 rearwardly and, consequently, therewith the proreleases suddenly the locking noses 30a.
  • the needle-carrying rod 14 together with the hollow needle 15 are also urged rearwardly thereby, so that the needle collapses again within the body of the ampull-a.
  • the patient has no opportunity, either before or after the injection, of ascertaining the presence of the hollow needle 15.
  • the ampulla illustrated in FIG. 6 is similar in its general structure and in its operation with that described with reference to FIGS. 1 to 3.
  • the annular spring 24 and the peripheral groove 14b associated with the latter are replaced by other safety means constituted, in the case of FIG. 6, by a spherical end 25a of the needle-carrying rod 25 and by a correspondingly shaped expansion of the boreformed in the piston 26 made of elastic material.
  • an axial compression has to be exerted on the protecting sleeve so as to urge suddenly in a forward direction the needle-carrying rod 25 with the hollow needle 27, this sudden movement being provided by the fact that the spherical end 25a of the rod 25 has first to overcome the resistance opposed by the corresponding section of the piston, after which it projects suddenly beyond the bore in the piston.
  • the engagement of the needle with a point of the patients body is thus performed in a manner similar to that described hereinabove, and it is only when the hollow needle 27 has actually reached the previously defined depth of penetration that the piston 26 is urged forwardly under the action of the expanding compression spring 18, so as to deliver the injection liquid into the hollow needle 27.
  • the maximum engagement of 'the needle 27 is defined by the fact that the spherical end of the needle-carrying rod 25 engages at the end of its forward movement the end of the chamber in the ampulla body, which end is provided with a narrow opening, as in the case of FIGS. 1 to 3.
  • the hollow needle remains in its projecting position after the actual injection has been brought to an end.
  • FIG. 8 illustrates in true size the ampulla of the abovedescribed types in its closed position.
  • the :ampul'la according to FIGS. 9 and 10 corresponds in its general structure with the embodiments already described; it is provided with a metal sleeve 40 in the shape of a cartridge sliding over the body of the ampulla made of synthetic material and constituted,
  • Said ampulla body forms also, as precedingly, a gmide for a piston 43 inside the axial bore of which the needle-carrying rod 44 of the injection needle 45 extends.
  • Said rod 44 is provided with an input port 44a opening in its front hollow section.
  • the rear element of the ampulla body is provided with a particular structure showing three longitudinal. slots 4111, while its rear end is of a slightly reduced diameter.
  • rear element includes furthermore an inner guidin projection 41b in the shape of a hollow cylinder out- Wardly carrying the compression spring 46.
  • Said plug 47 carries at its rear end two hook-shaped springs 48 anchored in said plug and the outer ends of which are held by the enclosing guiding projection 41b in engagernent with'the rear end of a reduced diameter of the rod 44 carrying the needle 4'5, as illustrated in FIG. 9.
  • the flange 47a carries a disc 49 showing, as in the case of the embodiment illustrated in FIGS. 1 to 3, elastic tongues directed rearwardly, 49a, and terminating with looking noses 49b. In the position illustrated in FIG. 9
  • the procedure is similar to that described hereinabove.
  • the ampulla being in the condition illustrated in FIG. 9, has its front end engaging a point of the patients body which is to receive the injection.
