Abstract
A fluid collecting container includes a fluid inlet, a fluid outlet, a front sheet and a back sheet. The front sheet and back sheet are fixed together at their edges and create a chamber in which the fluid can be collected. The fluid collecting container also has a channel having a first upper end fluidically connected to the fluid inlet and a second bottom end fluidically connected to the chamber. The channel is configured to increase the pressure drop at the fluid inlet once the fluid level in the chamber reaches the second bottom end.
Claims18
A fluid collecting container comprising:
- a fluid inlet;
- a fluid outlet;
- a front sheet;
- and
- a back sheet,
- the front sheet and the back sheet being fixed together at edges, creating a chamber in which fluid is collectable, wherein the edges comprise a top edge, a bottom edge opposite the top edge, a first lateral edge joining the top edge with the bottom edge, and a second lateral edge opposite the first lateral edge joining the top edge with the bottom edge,
- the fluid collecting container further comprising a channel having an upper end fluidically connected to the fluid inlet and a bottom end fluidically connected to a remainder of the chamber, wherein the channel extends along the first lateral edge, with the upper end and the fluid inlet located between the top edge and the bottom edge, and the bottom end spaced from and facing towards the bottom edge to thereby direct fluid exiting the channel into the remainder of the chamber towards the bottom edge,
- the channel configured to increase a pressure drop at the fluid inlet when a fluid level in the chamber reaches the bottom end,
- wherein a distance between the bottom edge of the fluid collecting container and the bottom end of the channel is dimensioned to allow a selected flowrate of the fluid from the channel toward the chamber.
6 more elements
An extracorporeal blood treatment device comprising:
- at least two fluid collecting containers, wherein each of the at least two fluid collecting containers comprises:
- a fluid inlet;
- a fluid outlet;
- a front sheet;
- and
- a back sheet,
- the front sheet and the back sheet being fixed together at edges, creating a chamber in which fluid is collectable,
- a channel having an upper end fluidically connected to the fluid inlet and a bottom end fluidically connected to a remainder of the chamber, the channel configured to increase a pressure drop at the fluid inlet when a fluid level in the chamber reaches the bottom end, wherein a distance between a bottom edge of each fluid collecting container and the bottom end of the channel is dimensioned to allow a selected flowrate of the fluid from the channel toward the chamber;
- and
- a waste liquid discharge line,
- the at least two fluid collecting containers being connected in a parallel fluid flow arrangement to said waste liquid discharge line.
