Two-chamber injection ampoule.

However, the further disadvantage is that the use of the noble, their urarchflufikenal and consequently also their strength, with regard to the previous transfer of the fluid from one to the other, was kept relatively large, extraordinary in the case of injections into often lost bad veins Brings trouble with them. tuck

The invention avoids disadvantages.

The two-point ampoule according to the invention differs from the known one in that the ampoule carries a piston at one end or has a piston-like design and is arranged with the piston so that it can be moved in a cylindrical container, which is di «second side with the piston of the ampoule chamber, and in that an existing or in the piston easily herste lbere! flow opening thereof provided, od by a in the ampoule in the longitudinal direction of sweet to be actuated rod. the like. is to use coat closed, and f easy to open ³ ir the Gebr & uchafslIL and after the f / iechvorgeng for the tniejktion it is just as easy to re-seal.

this ensures that the Spritz & copulle quickly is ready for geo-smoking.

In the case of the injection ampoule according to the invention, the mixing process is also considerably simpler and faster than the previously mentioned known embodiment with the plastic container that can be exchanged. There is no need to reposition a container. In the embodiment according to the invention, only the ampoule with the piston present on it needs to be sucked back in the surrounding cylindrical container. As a result, the Eemffler formed by the syliodrene container and the piston is caused, and a negative pressure arises in this chamber, as a result of which the liquid in the ampoule flows out of the same through the flow opening previously released by the manually operated rod

Pistons into those of the cylindrical container and piston educated Kömraer flows. K & eh closing the duroh flow opening by means of the rod, again operated by Hftnd, and attaching the insect & del on the cylindrical The container is then immediately ready for injection.

The result is that the flow opening in the piston can be opened or closed simply by turning the rod, for example by 180 °. For this purpose, it is provided, for example, that the rod has cavities and holes leading into the cavities, which, in order to open or close the flow, bring channels in or out of position opposite the piston and stopper / whereby the combustion of the » The rod can be limited by stops ".

If the opening 4 in the piston 2 is opened by the rod actuated and the nozzle 1 bit is withdrawn from the piston 2 as a cylindrical container 3, the kerätaer D formed by the piston and a cylindrical container expands ) ela negative pressure, according to which the liquid eue the Kesmer e flows through the passage opening 4 into the Keauner b, and the ^ ischvorgßng begins. A groove 5 or anger present in the rod 5 ensures the air balance in the chamber β of the ampoule 1 because the Ptab 5 was moved backwards when the passage opening 4 was pressed and with the groove 5 partly outside of the ampoule 1 and the stopper 6. When the process is complete, the door flow opening 4 in the flask is opened . rieder closed by the rod 5. From the cylindrical container 3 provided with an attachment 25, the closure cap 26 is now attached and an injection needle, which is not shown, is attached to the attachment 25, whereupon the injection ampoule is ready for injection.

To ensure a good seal of the passage opening 4 at / iv

To reach the sole of the same through the rod 5 and to allow the rod to be screwed back to release the ureohlaßöffnuüg, the rod 5 is provided with a thread 9 as a reinforcement 8 and a reinforcement thereof. It is also provided that the two-chamber injection ampoule is designed in such a way that the through-flow opening in the piston 2 can only be ^{released or closed by preheating the rod 5, for example by 1RO O} , a similar design sees cavities 10, 11 in the rod 5 before, wherein the open end of the cavity 11 ends in the chamber b and laterally holes lead into the cavities 10, 11, which by turning the rod 5 for "opening or closing with the piston 2
