Abstract

A drainage container device for collecting suctioned bodily fluids by means of a vacuum source includes a drainage container with a suction port to be connected with the vacuum source; an essentially one-piece container lid for closing and opening the drainage container, and with a drainage port to be connected with a patient drainage line; a suction bag for holding the suctioned bodily fluid, which is arranged on the container lid and accommodated by the drainage container; a channel that runs at least partially through the container lid, which joins an interior space of the suction bag with the suction port by way of an interior space of the drainage container, and is otherwise closed, and a protective element, in particular a filter, for avoiding overflow and/or contamination of the vacuum source by a suctioned bodily fluid.

First claim

What is claimed is:

1. A drainage container device for collecting suctioned bodily fluids by means of a vacuum source, wherein the drainage container device comprises:
a drainage container with an outer wall and with a suction port to be connected with the vacuum source;
a container lid for closing and opening the drainage container, having a drainage port to be connected with a patient drainage line;
a suction bag for holding the suctioned bodily fluid, which is arranged on the container lid and accommodated by the drainage container;
a channel which runs at least partially through the container lid, which joins an interior space of the suction bag with the suction port by way of an interior space of the drainage container, and which channel is otherwise closed, and
a protective element for avoiding at least one of overflow or contamination of the vacuum source by a suctioned bodily fluid,

wherein
the suction port is arranged on the outer wall of the drainage container such that a vacuum can be applied by the vacuum source in the interior space of the drainage container between the suction bag and the outer wall of the drainage container;
wherein
the protective element is situated in the channel, and
the channel incorporates a chamber in which the protective element is arranged;
and wherein
the chamber is tightly sealed with a separate chamber cover from an exterior side of the container lid facing away from the suction bag.

2. A suction bag unit for use in a drainage container device, wherein the suction bag unit comprises:
a container lid for closing and opening the drainage container, and with a drainage port to be connected with a patient drainage line;
a suction bag for holding the suctioned bodily fluid, which is arranged on the container lid for accommodation in the drainage container;
a channel which runs through the container lid and joins an interior space of the suction bag with an interior space of the drainage container for connection with a suction port arranged on an outer wall of the drainage container, such that a vacuum can be applied by a vacuum source in the interior space of the drainage container between the suction bag and the outer wall of the drainage container, wherein the channel is otherwise closed, and
a protective element for avoiding at least one of overflow or contamination of the vacuum source by suctioned bodily fluid,

wherein
the protective element is situated in the channel, and
the channel incorporates a chamber in which the protective element is arranged;
and wherein
the chamber is tightly sealed with a separate chamber cover from an exterior side of the container lid facing away from the suction bag.

3. The suction bag unit according to claim 2 , wherein the chamber comprises a floor directed toward the interior space of the suction bag, with suction openings for connecting the interior space of the suction bag with the interior space of the drainage container.

4. The suction bag unit according to claim 2 , wherein at least one splashguard is present, which safeguards the protective element against bodily fluids in relation to the interior space of the suction bag.

5. The suction bag unit according to claim 3 , wherein at least part of the suction openings are each provided with a splashguard element that projects toward the interior space of the suction bag, wherein each splashguard element forms a nonlinear connection between the interior space and the chamber, and acts as a splashguard.

6. The suction bag unit according to claim 4 , wherein the splashguard is formed by a protective cap, which, on the side of the chamber facing the interior space is spaced apart from the chamber, and covers the chamber.

7. The suction bag unit according to claim 2 , wherein the container lid has a main part being made in one piece, and wherein the chamber is situated in this main part of the container lid.

8. The suction bag unit according to claim 2 , wherein the protective element is inserted into the chamber from this exterior side.

9. The suction bag unit according to claim 2 , wherein the protective element is a filter.

10. The suction bag unit according to claim 2 , wherein the protective element is planar and flat.

11. The suction bag unit according to claim 2 , wherein a transverse central axis of the protective element aligns with a transverse central axis of the chamber.

12. The suction bag unit according to claim 2 , wherein the chamber is spaced apart from the midpoint of the container lid.

13. The suction bag unit according to claim 2 , wherein the interior of the chamber comprises a continuous projection to support the protective element, wherein the projection faces an exterior side of the container lid facing away from the interior space of the suction bag.

14. The suction bag unit according to claim 2 , wherein the drainage port comprises a spout that projects into the interior space of the suction bag, wherein the spout is longer on its side facing the chamber than on its opposite side.

15. The drainage container unit according to claim 1 , wherein the container lid is an essentially one-piece container lid.

16. The suction bag unit according to claim 2 , wherein the container lid is an essentially one-piece container lid.
