Abstract
This device comprises means for supporting a first and a second chamber, means for allowing these chambers to communicate with each other, and a movable member for applying a suitable force to reduce the volume of the first chamber. The means for supporting the first and second chambers comprise two tubular bodies, each open at one end, the dimensions of these openings being such as to allow these tubular bodies to be brought together and slid one into the other, a double-ended needle, with associated guide means, being interposed between the said chambers in such a way that when the said tubular bodies are slid towards each other, the respective ends of the said needle pass into the chambers and the volume of the chamber is reduced.
