NEW AMPOULE-SYRINGE Filed Nov. 22, 1955 2 Sheets-Sheet 2 United States Patent NEW AMPOULE-SYRINGE Antonio da Cunha Reis, Lisbon, Portugal Application November 22, 1955, Serial N 0. 548,496

7 Claims. (Cl. 128-218) This invention relates to syringes.

It is an object of the invention to provide an improved syringe which enables preparation for injections in a period of time.

It is a further object of the invention to provide an improved syringe capable of working equally Well with oil and aqueous solutions and with substances provided in the form of a powder or crystal which are to be dissolved in a fluid carrier.

It is still a further object of the invention to provide an improved syringe with which it is not necessary to draw the material to be dispensed into the same through an injection needle. Advantageously this permits a saving of the material to be dispensed since frequently much of this material is left in its original container.

In achieving the above and other of its objectives, the invention contemplates the provision of a cylinder body wherein is disposed a piston comprising first and second concentric hollow tubes having means thereon for fixing the relative positions of the tubes. The hollow tubes are displaced in a predetermined manner which will be described below so that the piston operates firstly, to prepare a material in the syringe for injection, and secondly, as a simple piston to eject the material from the syringe.

To facilitate an understanding of the invention, a preferred embodiment thereof will next be explained, in detail, with reference to the accompanying drawing in which:

Fig. 1 is an elevational view of a syringe provided in accordance With the invention with the components thereof assuming relative positions for effecting a movement of the syringe piston in the body of the syringe;

Fig. 2 is an elevational view of the syringe of Fig. 1 with the parts of the syringe in position for storage;

Fig. 3 is an axial section of the syringe with certain of the parts disengaged so as to facilitate an understanding of the construction;

Fig. 4 illustrates the outer body of the syringe;

Fig. 5 illustrates a nozzle cover employed by the syringe;

Fig. 6 illustrates one of the members of the piston of the syringe;

Fig. 7 illustrates a plug employed in the syringe for confining the material to be dispensed;

Fig. 8 illustrates a washer employed in connection with the piston of the syringe;

Fig. 9 illustrates a further member of the piston of the syringe;

Fig. 10 illustrates a head which is connected to the piston of the syringe for manipulation thereof; and

Fig. 11 illustrates a capsule in which material may be stored within the syringe.

The complete collection of elements necessary for providing a syringe in accordance with the invention is illustrated in each of Figs. 1-3, the separate components of the syringe being illustrated in Figs. 4-11. The illustrated syringe provides for accommodating, within its interi'or, one or more materials to be dispensed, these materials being hermetically sealed within the syringe and the syringe requiring an injection needle to be affixed to its end for purposes of dispensing the stored material.

The syringe includes an outer cylindrical body 1 hav ing a smooth internal bore and terminating in a conical nipple or nozzle 2 the interior of which is hollow so that the bore of the casing 1 can communicate to the outside.

The cylindrical outer body or casing 1 is shown more particularly in, Fig. 4 wherein it can be seen that the nipple 2: is afiixed in conventional manner at 7 to the main body of this component. It can also be seen that the nipple 2 is provided with an external thread 3.

The casing 1 accommodates a piston which includes an inner hollow tube 13 externally threaded along the greater part of its length and a second hollow tube 8 which is internally threaded in such a manner that it is capablev of threadably engaging the first hollow tube 13. The hollow body 8 defines, at one end, an annular groove 10 capable of accommodating a ring or rubber washer 11 (see Fig. 8) so that an air tight seal is provided between the piston and the internal bore of the casing I. The washer 11, of course, permits a sl'idable movement between the piston and the casing.

The hollow body 8 defines an opening 9 in which is accommodateda plug 18 (see Fig. 7) which itself defines a blind bore. The blind bore is adapted for accommodating the lower extremity of a hollow needle 15 which is connected with an ampoule or capsule 17 in which may be storeda material which is to be dispensed. This capsule is normally stored in the interior of the piston in a manner which will hereinafter be made apparent.

To enable a manipulation of the piston which consists of the hollow members 8 and 13 there is provided a head or knob 14 capable of being afiixed to the hollow body 13 in conventional manner such as by welding or by a set screw.

To close off the nipple 2 there is provided a conical cap (see Fig. 5) having a rim 6 adapted for tightly abutting the lower extremity of the casing 1, the cap being hollow and having an internal thread 5 capable of engaging the thread 3 of the nipple 2. It is to be noted that the cap can be provided with a pin. 4 capable of penetrating the opening of the nipple 2 so as to block the same.

With the syringe in storage position as indicated in Fig. 2, the hollow tubes 8 and 13 are engaged in such a manner that the needle 15 of the capsule 17 rests in the blind bore or well of the plug 18 with the head 14 resting against the upper extremity of the casing 1. In this position the respective threads of the tubes 8 and 13 are not fully engaged so that upon a turning of the tube 13 in the tube 8 in a direction so as to cause a further engagement between these tubes, the needle 15 will be caused to penetrate the plug 18 whereupon the material from the capsule 17 will be emptied into that portion of the casing which is confined between the lower extremity of the casing and the lower end of the piston. Alternatively material can be stored in the space 16 and this material can be re-positioned in a manner similar to that indicated above.

With the material adjacent the nipple 2 it is possible to unscrew the inner hollow tube 13 substantially but not completely from the hollow tube 8 so as to increase the effective length of the piston. With the piston so extended, the cap can be removed from the nipple 2 and an injection needle threaded thereupon. The syringe can then be used in conventional manner.

From what has been stated above it will be appreciated that the invention provides a syringe in which the material to be dispensed can be stored. The invention, morer 3 over, provides for conveniently releasing the material for injection and in achieving this objective provides for accomplishing its purpose with a minimum effort and with no exposure of any of the elements or materials which will be used for medical purposes to the possibility of contamination.

There will now be obvious to those skilled in the art many modifications and variations of the structure set forth which do not depart essentially from the spirit of the invention as defined in the following claims.

What is claimed is:

l. A syringe for use with a sterile needle comprising a casing adapted for communicably engaging said sterile needle and a piston slidably engaged within said casing for ejecting material through said sterile needle, said piston comprising a first hollow tube engaging said casing, a second hollow tube within and threadably engaging said first hollow tube, said second hollow tube being axially adjustable with respect to said first hollow tube and adapted for substantially complete insertion therein whereby the piston length may be controlled, and means on said first and second hollow tubes for fixing the relative positions thereof.

2. A syringe as claimed in claim 1 wherein said first hollow tube is provided with an annular groove and further comprising a ring engaging said groove for slidably sealing said piston with said casing.

3. A syringe as claimed in claim 2 comprising a stud, said first hollow tube being provided with an end aperture for engaging said stud, a capsule positioned in said second hollow tube, and a needle afiixed to said capsule, said second hollow tube being provided with an end aperture for the passage of said needle, said plug being provided with a well for accommodating the end of said needle with said first and sepond hollow tubes at a predetermined axial adjustment;

4. A syringe as claimed in claim 3 wherein said first and second hollow tubes are axially adjustable to permit the forcing of said needle through said plug whereby said capsule empties intothe space defined between said piston and said casing.

5. A syringe as claimed in claim 4 comprising a threaded nipple on said casing communicating with said space and adapted for engaging said sterile needle, and a threaded cap for engaging and sealing off said nipple.

6. A syringe as claimed in claim 5 comprising a head member engaging said second hollow tube for the manipulation of said piston.

7. A syringe as claimed in claim 6 comprising a mounting on said casing for detachably supporting said sterile needle whereby said sterile needle is conveniently accessible for attachment to said nipple.
