The invention provides an injection device comprising an open cavity (2), an injection needle (9) projecting from the bottom of this cavity (2), a first leakproof compartment (6) delimited by a first section of a mobile barrier (11), first devices (13) for displacing the said first section of a mobile barrier (11) to vary the volume of the compartment, at least one passage (7) communicating between the said first leakproof compartment (6) and the said cavity (2), a second leakproof compartment (5) for a product to be injected, delimited by a second section of a mobile barrier (10), and second devices (12) for displacing the said second section of a mobile barrier (10) to vary the volume of the compartment. The said first and second leakproof compartments (5, 6) extend longitudinally within a tubular body (1). The cavity (2) is located at one end of this tubular body, while the said first and second devices (12, 13) for displacing the said first and second sections of a mobile barrier (10, 11) are accessible at the other end of the said tubular body (1). that they can be found put on the connection of the tube (42), two clamps (60, 62) at the distance, and cut by the same knife (50) placed in the middle of the symmetrical plane. Ovaj pronalazak ukljucuje jedan instrument za injekcije koji ima otvorenu supljinu (2), iglu za injekcije (9) koja se projektuje sa dna ove supljine (2), prvi odeljak zaptiven da ne moze da curi (6) koji je ogranicen prvim delom pokretne barijere (11), prve naprave (13) za pomeranje pomenutog prvog dela pokretne barijere (11) da bi se mogla menjati zapremina odeljka, najmanje jedan prolaz (7) koji komunicira izmedju pomenutog prvog odeljka koji je zaptiven da ne curi (5) za proizvod koji ce se ubrizgavati injekcijom, koji je ogranicen drugim delom pokretne barijere (10) i druge naprave (12) za pomeranje pomenutog drugog dela pokretne barijere (10) da se moze menjati zapremina odeljka. Pomenuti odeljci koji su zaptiveni da ne cure (5, 6) sire se longitudinalno u tubularnom telu (1). Supljina (2) se nalazi na jednom kraju ovog tubularnog tela, dok su pomenuta prva i druga naprava (12, 13) za pomeranje pomenutog prvog i drugog odeljka pokretne barijere (10, 11) dostupne sa druge strane pomenutog tubularnog tela (1). Ovaj pronalazak uklju uje jedan instrument za injekcije koji ima otvorenu šupljinu (2), iglu za injekcije (9) koja se projektuje sa dna ove šupljine (2), prvi odeljak zaptiven da ne mo e da curi (6) koji je ograni en prvim delom pokretne barijere (11), prve naprave (13) za pomeranje pomenutog prvog dela pokretne barijere (11) da bi se mogla menjati zapremina odeljka, najmanje jedan prolaz (7) koji komunicira izmedju pomenutog prvog odeljka koji je zaptiven da ne curi (5) za proizvod koji e se ubrizgavati injekcijom, koji je ograni en drugim delom pokretne barijere (10) i druge naprave (12) za pomeranje pomenutog drugog dela pokretne barijere (10) da se mo e menjati zapremina odeljka. Pomenuti odeljci koji su zaptiveni da ne cure (5, 6) šire se longitudinalno u tubularnom telu (1). Šupljina (2) se nalazi na jednom kraju ovog tubularnog tela, dok su pomenuta prva i druga naprava (12, 13) za pomeranje pomenutog prvog i drugog odeljka pokretne barijere (10, 11) dostupne sa druge strane pomenutog tubularnog tela (1).$The invention provides an injection device comprising an open cavity (2), an injection needle (9) projecting from the bottom of this cavity (2), a first leakproof compartment (6) delimited by a first section of a mobile barrier (11), first devices (13) for displacing the said first section of a mobile barrier (11) to vary the volume of the compartment, at least one passage (7) communicating between the said first leakproof compartment (6) and the said cavity (2), a second leakproof compartment (5) for a product to be injected, delimited by a second section of a mobile barrier (10), and second devices (12) for displacing the said second section of a mobile barrier (10) to vary the volume of the compartment.
