| abstract |
A device (1) for closing containers or lines for administering medical or pharmaceutical fluids, comprising a first tubular element (3) and a second tubular element (4), which are open at the respective opposite ends and are mutually associated, at a respective end, so that they are mutually substantially coaxial and can move axially so as to slide and/or rotate with respect to each other, their respective free ends being respectively associable with the mouth of a container or an administration line of a fluid and with the mouth of a tank for feeding the fluid to the container, or to the administration line, or to the inlet of a fluid user device, and a valve element (16) for adjusting the flow of the fluid, which is formed inside the first and second tubular elements (3, 4), the sliding and/or relative rotation of the first and second tubular elements being adapted to move the valve element (16) from a closed configuration for blocking the flow of fluid to an open configuration for the inflow of the fluid from the tank to the container or to the administration line or from the container or from the administration line to the user device, and vice versa. |
