Hemodialysis salt container with ventilation

摘要

In a rigid hemodialysis salt container of plastic material including a venting valve formed in a container wall with a venting opening extending through the container wall, a seal member covers the venting opening at the inside of the container wall and is connected to the container wall by cementing or welding such that, with the occurrence of a predetermined pressure difference between ambient air pressure and a vacuum generated in the container, the seal member is at least locally ripped off.

主权项

1. A hemodialysis salt container (1, 2) in the form of a single use container having rigid walls provided with a coupling arrangement (3) for establishing a flow connection with a dialysis apparatus for conducting dialysis liquid through the salt container but which is otherwise sealed in an airtight manner,
said container including a venting valve (4) with a venting opening (41) formed in the container wall and a seal member (42) connected to the container wall by local cementing or welding connections so as to cover the venting opening (41) on the inside of the container wall, the cementing or welding connections being so dimensioned that, when a certain pressure difference between the ambient air pressure and a vacuum generated by the dialysis apparatus in the interior of the container is reached, the seal member (4) is at least locally ripped open.
