Definitions
- the present invention relates to a hypodermic syringe which is advantageously used for hypodermic injections by the patient himself.
- Syringes of this type known hitherto do not meet requirements satisfactorily. They consist of a housing accommodating the ampule and an injection needle sliding therein and having two pointed ends, as well as of a piston subjected to the action of a compression spring and sliding in the housing, and a locking and release mechanism for the piston which upon release of the locking mechanism and through means for the relieved spring drives the needle out of the housing so that the contents of the ampule are discharged through the needle.
- a housing accommodates the ampule with the needle and the actuating mechanism for the syringe each form self-contained units which can be assembled and replaced to form the complete syringe.
- the unit containing the actuating mechanism is conveniently fitted in a long housing, the forward part of which is designed to replaceably receive the chamber containing the ampule unit.
- the transparent ampule of plastic material enables a control with respect to foreign matter and air bubbles. It is unbreakable and since it is accommodated in a vapor-proof chamber, a long storability of the hypodermic syringe is possible. Without a vapor-proof sealing, the contents would gradually escape through the walls of the plastic ampule.
- a shaft of the piston for actuating the hy- 3,182,660 Patented May 11, 1965 "ice podermic syringe extends through the bottom of the housing against which rests the compression spring acting on the piston, the end of the shaft having an external projecting collar tapered on both sides, while on the outside of the housing bottom radially movable locking members are arranged around the piston shaft in a manner, so that in their inner end position they engage behind the collar and are enclosed by means of a retainer ring located in a release cap and axially displaceable with the latter, which is axially displaceable on the housing, so that in its other end position the retainer ring releases the locking members to enable the latter to be moved radially in outward direction by the advancing piston which is thus released.
- the locking members consist of balls or rollers which are engaged or released by the axially displaceable release member, so that they engage behind the collar provided on the piston shaft or are moved in outward direction by the collar through the action of the compression spring acting on the piston.
- the locking members are rigid parts which are not subjected to particular wear even after frequent use of the hypodermic syringe, as might be the case, when the locking members are formed of or attached to springs which design, of course, is also possible without departing from the spirit of the present invention.
- FIGURE 1 is an axial section of the ampule unit
- FIG. 2 is an axial section of the unit incorporating the actuating mechanism, without the locking means for the piston shaft and the release means;
- FIGS. 3, 4, S and 8 are fragmentary axial sections of different embodiments of the locking means for the piston shaft, accommodated in the release cap;
- FIG. 6 is a section along the lines 6-6 of FIG. 3;
- FIG. 7 is a section taken along the lines 77 of FIG. 4.
- FIG. 9 is a section along the lines 9-9 of FIG. 8.
- a housing accommodating the ampule is disclosed. Substantially, it consists of a cylindrical container 1 to guide an ampule 2 containing the solution for the injection.
- the ampule 2, as well as the container 1 are closed by a piston-like plug 3.
- the ampule 2 is provided with a socket 4 receiving a slidable hypodermic needle 5, which is tapered at both ends.
- a point of the hypodermic needle 5 is disposed opposite a diaphragm 6 closing the ampule 2.
- the forward end of the needle 5 projects into a plug 7 closing the container 1 at the needle end. This end is in front of another diaphragm 8 which is pierced by the needle 5 when the latter is actuated.
- the container 1 After filling and closing under sterile conditions, the container 1 forms a self-contained unit which can be handled without endangering the sterility of its contents.
- FIG. 2 a sectional view of the part of the syringe incorporating the actuating mechanism is disclosed, which substantially consists of a housing 9 having an extension 10 to receive the ampule unit shown in FIG. 1.
- a collar 11 is'provided at the front end of the housing part 10, to accommodate a replaceable spring ring 12 which retains the entire ampule unit in the housing 10.
- a piston 13 is guided in the rear part of the housing 9, which piston 13 rests with its forward collar 14 on the piston-like plug 3 of the ampule 2 when the different parts are fitted into each other and which piston 13 has a shaft 15 projecting through an opening 16 in the housing bottom 17.
- a compression spring 18 1S arranged inside the housing 9 between the housing bottom 17 and the collar 14 at the forward end of the'piston 13 to actuate the latter.
- a release cap 19 extends over the rear end of the housing9.
- the tensioned compression spring 18 In the initial position of the hypodermic syringe, the tensioned compression spring 18 must be secured.
- the end of the piston shaft 15 is provided with an external collar 29 tapering at both sides and cooperating with suitable locking means.
- locking means are used which are formed of tongues 21 arranged around the piston shaft 15, fixed in the housing bottom 17 and having near their ends an inner shoulder 22. The latter engages behind the collar 20.
- the ends of the tongues 21 are provided with guides 23 to support the tongues 21 in a retainer ring 24 which is inserted into the inside of the release cap 19.
- the ring 24 has a collar 25, engaging behind the guides 23 of the locking members 21, thereby securing the release cap 19 against accidental withdrawal from the housing 9.
- the release cap 19 is fitted in a manner suchthat a chamber 26 is formed at its bottom which accommodates a cam disc 27.
- the latter is arranged eccentrically on a shaft 28 of a set button 29 journalled in the release cap 19, and it is dimensioned such that by rotating the button 29 axis of the latter can be turned into the axis of the inner chamber 30 inside the locking members 21.
- FIG. 3 The position of the different parts in initial position of the syringe is illustrated'in FIG. 3.
- the release cap 19 rests on the ends 23 of the locking members 21, so that no axial displacement of the release cap 19 can take place. Only after rotation of the button 29 and, thereby, of the axis of the cam 27 to coincide with the axis of the empty chamber 30, can the release cap 19 be pushed further axially over the housing 9.
- the retainer ring 24 is removed from the guides 23 of the locking members 21 which are no longer enclosed.
- the tensioned compression spring 18 acting on the piston 13 drives the latter forward, thereby spreading the locking members 21 by means of the conical collar 20 and the cam-shaped projections 22 on the locking members 21, so that the latter actually release the piston.
- the piston 13 can be returned into its initial position, when after removal of the entire ampule unit the piston 13 is forced back.
- the collar 20 slides over the collars or neck portions 22 of the locking members 21.
- the release cap 19 is withdrawn somewhat from the housing 9, so that the retainer ring 24 again encloses the locking members 21.
- the cam 27 is turned back into its locking position.
- the actuating mechanism is locked again in its initial position.
- the piston 13 is locked by means of rollers 32 having conical ends and being journalled with considerable play on axial pins 31 on the outside of the housing bottom which is shaped accordingly, the rollers 32 engaging behind the collar 20 on thepiston shaft 15 and bearing against the inside of the retainer ring 24 of the release cap 19.
- One of the pins 31 has an extension 33 which rests on the thick bottom of the release 19.
- the bottom of the cap is provided with a recess 34.
- FIG. 5 A simplified embodiment of the hypodermic syringe is disclosed in FIG. 5.
- the collar 20 on the piston shaft 15 is enclosed by resilient retainer members 35 which are fixed at the bottom of the release cap 19 and which are provided, at their ends, with two recesses 36 and 37 disposed behind one another. Furthermore, the ends 38 of the springs 35 are bent outwards.
- the bottom of the release cap 19 is provided with a push-button 39 which with its head 40 rests on the first recess 36 of the springs.
- the release cap 19 is fitted to the housing 9 so that it cannot be moved axially.
- the spring By pressing the button 39, the spring is radially forced outwards so that the recesses 37 release the collar 20 to enable the piston to be pushed forward through means of the action of the spring 18.
- the collar 20 bears on the outwardly bent ends of the springs 38. These are spread apart and their bent portions 37 again rest behind the collar 20.
- the housing 9 is provided, behind its bottom 17 with an extension guiding a release ring 46.
- the latter has an inner collar 47.
- the ring is also guided by means of the collar 47 to be axially displaceable on a bushing 48 which encloses the piston shaft 15' and which is provided on the housing bottom 17.
- the ring 46 is provided with a small bore 49 and a Wide bore 50.
- the locking members in this case are formed of balls 51 which are arranged around the piston shaft 15', have a rather wide bore 52 and are secured in their circular arrangement around the piston shaft 15 by means of a retainer ring 53.
- the release ring 46 extends beyond the housing extension 45 and is provided with a cover 54 closing the housing 9
- the rim of the housing 45 has recesses 55 to receive projections provided on the cover 54 when the latter is rotated together with the release ring 46.
- a hypodermic syringe for self administering injections comprising a first unit and a second unit receiving said first unit,
- said first unit comprising a cylindrical housing open at one end and having a bottom wall to close the other end,
- a piston having a shaft extending therefrom and disposed in said cylindrical housing adjacent said bottom wall and said shaft extending through said central opening of said bottom wall,
- said piston having a collar at its end remote from said shaft
- said second unit comprising a cylindrical metal container fittingly and immovably disposed in and at the open end of said cylindrical container,
- hypodermic needle axially m ovably disposed in said metal container between said first diaphragm and said second diaphragm and having pointed ends
- said cylindrical metal container is set off inwardly at its open end to form an inner diameter substantially identical with the inner diameter of said ampule and the outer diameter of said first plug.
