Container for holding a liquid
View Patent ↗A container for holding a liquid, in particular an infusion liquid or irrigating liquid, comprising a liquid phase containing the liquid and a gas phase, wherein, in the operating position, a liquid opening is formed in the lower region of the container and wherein the container has a gas opening. The gas opening is formed by a gas pipe which is inseparably connected to the container and has a first gas pipe end and a second gas pipe end. The first gas pipe end extends into the gas phase of the container and is provided with a closure. The second gas pipe end leads to the outside of the container.
1. A container, comprising a liquid phase and a gas phase, wherein, in an operating position, a liquid opening extending into the liquid phase is formed in a lower region of the container and wherein the container includes a gas opening, which gas opening is independent of the liquid opening and is formed by a gas pipe which includes a first gas pipe end and a second gas pipe end,
wherein the first gas pipe end extends into the gas phase of the container and wherein the second gas pipe end leads to an outside of the container, wherein
the gas pipe is inseparably connected to the container,
the first gas pipe end is provided with a closure,
the gas pipe with the first gas pipe end extends into the gas phase from a region of the container which is lower in the operating position or from a region of the container which is upper in the operation position, and
the container is formed from a plastic film which has been folded and welded at the edges, with the gas pipe and the plastic film being welded to each other.
2. The container according to claim 1 , wherein the closure is formed by a first safety device against breaking, wherein the gas opening is released only as a result of the first safety device against breaking being bent.
3. The container according to claim 1 , wherein the closure is formed by a plug which is displaceable from a closing position, which closes the gas opening, into a release position, which opens the gas opening.
4. The container according to claim 1 , wherein the container has an elastic design and is made of a synthetic material.
5. The container according to claim 1 , wherein the liquid opening is formed by a liquid pipe which is welded to the plastic film and has a first liquid pipe end and a second liquid pipe end, wherein the first liquid pipe end extends into the liquid phase and the second liquid pipe end leads to the outside of the container.
6. The container according to claim 5 , wherein the gas pipe extends with the first gas pipe end into the gas phase from the region of the container which is lower in the operation position, and wherein the second gas pipe end and the second liquid pipe end form a connection unit.
7. The container according to claim 5 , wherein the second gas pipe end comprises a Luer connection.
8. The container according to claim 5 , wherein the second liquid pipe end comprises a Luer connection.
9. The container according to claim 1 , wherein the liquid opening has a second safety device against breaking, wherein the liquid opening is released only as a result of the second safety device against breaking being bent.
10. An eye surgery device comprising:
a surgical handpiece,
a control device, and
a compressor unit,
wherein the eye surgery device includes the container according to claim 1 , wherein the surgical handpiece is connected to the liquid opening my means of a hose, wherein the compressor unit is connected to the gas opening and is designed for controlling a gas supply into the container and wherein a liquid delivery is controllable on the surgical handpiece by means of the control device.
11. The container of claim 1 , wherein the liquid is an infusion liquid or an irrigating liquid.
