<p>To ensure the most careful mixing of the liquid and the dry phase in a two-compartment carpule (1) this carpule (1) is placed in a housing (17) and secured by mounting a needle (19). A piston rod (9) may then be passed forward to mix the medicine, this mixing being obtained by a uniform forwards movement of the piston rod, air in the mixing chamber being let out through the needle (19). For subsequent setting a dose of the mixed medicine to be injected, the movement of the piston may be preset by separating through a threaded connection (26) a press part (10, 20) from the piston rod (9). By this separation the movement of the piston rod (9) is restricted during the injection and consequently the injected dose is limited.</p> |
