Filling device of a fluid system

摘要

Disclosed is a filling device of a fluid conducting system of an extracorporeal blood treatment device that includes a spike for connecting to the single fluid connector of a medical fluid container and a manually operable fluid blocking mechanism arranged directly downstream of the spike that fluidly connects with the spike while the filling device is in operation. The fluid blocking mechanism has at least one fluid outlet connector that is adapted so that a line section or hose of the fluid conducting system such as the arterial line section of a blood purification device can be connected to it in a detachable manner while the filling device is in operation.

1. Filling device of a fluid conducting system of a medical treatment device, comprising:
a spike adapted for connecting a fluid connector of a medical fluid container to the fluid conducting system, the spike having a pricking cannula on which there is a spike outlet connector with a receiving space downstream of the pricking cannula, the spike outlet connector configured such that a line section or hose of the fluid conducting system can be connected in a detachable manner while the filling device is in operation; a manually operable fluid blocking mechanism positioned downstream of the pricking cannula in the receiving space, the fluid blocking mechanism fluidly connected with the spike while the filling device is in operation, wherein:
the fluid blocking mechanism is installed in the receiving space to form an integral unit with the spike such that the fluid blocking mechanism is mechanically activated in an open position upon or through connection of the line section or hose of the fluid conducting system to the spike against fluid flow in the spike; andthe fluid blocking mechanism is a manually operable poppet valve having a valve body axially mounted in the receiving space that interacts with a valve seat in the receiving space; and a pre-tensioning spring arranged on a side of the valve body facing away from the valve seat to press the valve body against the valve seat.
