BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a schematic view of an embodiment of the inventive container with a drainage line for drainage of fluids or wound secretion in a side view;

(2) FIG. 2 is a schematic view of the embodiment of the inventive container according to FIG. 1 in a perspective top view; and

(3) FIG. 3 is a schematic view of a further embodiment with two inventive containers with a drainage line for drainage of fluids or wound secretion in a side view.

DETAILED DESCRIPTION

(4) FIG. 1 shows a container 1 in an embodiment of the invention for drainage of fluids or wound secretion in a schematic side view. The container 1 has an inlet opening 3, wherein the inlet opening 3 is connected with a drainage line 2 or a drainage tube 2. Further the container 1 has an outlet opening 4 for releasing waste air accumulated inside the container 1 during drainage. During manufacturing the container 1 has been pre-evacuated, presently with about 40000 Pascal [Pa], which corresponds to about 400 mbar. The container 1 consists of a rigid and transparent plastic, so that the container 1 does not change is form during evacuation. Further, the present container 1 is designed as a so-called Redon-bottle.

(5) Directly at the outlet opening 4 of the container 2 a first tube-like element 7 is located, wherein the first tube-like element 7 of the outlet opening is clampable by a first clamping device 5, presently a slide-clamp 5. Thereby the outlet opening 4 of the container 1 is sealable.

(6) Further, directly at the inlet opening 3 of the container 1 a second tube-like element 8 is located, wherein the second tube-like element 8 of the inlet opening 3 is clampable by a second clamping device 6, presently a slide-clamp 6. Thus, the inlet opening 3 of the container 1 is sealable by the slide-clamp 6. The inlet opening 1 of the container 1 comprises a so-called and standardized Luer-Lock connector 10, by which a corresponding counter-part of the drainage line 2 is easily connectable to the container 1.

(7) The inventive container 1 is transferable in a first and in a second operating condition, wherein in the first operating condition the outlet opening 4 is closed, presently by pressing and adjusting the slide-clamp 5. If the inlet opening 3 is open, suction is generated at the inlet opening 3 due to the vacuum in the container 1 resulting from the pre-evacuation of the container 1. Via drainage line 2 located at the inlet opening 3, which in turn is connected to the not shown body and/or tissue opening of the human or animal body, fluid or wound secretion or such the like can be transferred by aspiration into the container 1.

(8) If the outlet opening 4 of the container is opened, the container is transferred into a second operating condition, wherein via the opened outlet opening 4 air can enter the container 1, so that the vacuum inside the container 1 is neutralized. After no vacuum is present inside the container 1, the drainage functions according to the gravity drainage principle, which is a particular gentle drainage.

(9) Further, the outlet opening 4 comprises a filter 9, wherein using the filter 9, as a kind of valve, waste air can be released from the container 1 or enter the container 1. The filter 9 can be for example designed that pressure differences between the inside of the container 1 and the air surrounding the container 1 are compensated. Further, the filter 9 is preferably designed that the filter 9 is permeable for gas, particular air, and impermeable for liquids, like for example wound secretion.

(10) The container also has a scale 11, from which the user can identify the actual filling capacity of the container 1. Using a holder 12 the inventive container 1 can be mounted to a stand, IV-stand or such the like device.

(11) FIG. 2 shows a schematic view of the embodiment of the inventive container 1 according to FIG. 1 in a perspective top view. The container 1 is presently in the first operating condition, in which the outlet opening 4 is sealed. This is accomplished by the slide-clamp 5. The slide-clamp 5 comprises a recess tapered in a longitudinal direction, wherein the recess is tapered at one end in such a way, that the tube-like element 7 of the outlet opening 4 located inside the recess is clamped or pinched off. The opposing end of the recess however is wide enough, that the tube-like element 7 of the outlet opening 7 arranged inside the recess is not clamped or pinched off.

(12) A further slide-clamp 6 is arranged at the second tube-like element 8 of the inlet opening 3 of the container 1. In contrast to the slide-clamp 5 the second tube-like element 8 arranged inside the recess is in the widened part of the recess, so that the second tube-like element 8 is not clamped and therefore the inlet opening 3 of the container 1 is open. Suction is created at the inlet opening 3 by the vacuum inside the container 1, so that presently the first operating condition is adjusted and a vacuum-drainage is performed.

(13) In FIG. 3 a further embodiment of a system for drainage of fluids or wound secretion is shown, which comprises two containers 1. The inventive containers 1 are connected to each other via a tube like connection piece or connecting line 13. A connection between the outlet opening 4 of the shown left container 1 is created to the inlet opening 3 of the shown right container 1. For easy handling by a user, as presently shown, the inlet or outlet openings 3 and 4 of the containers 1 each have Luer-Lock connectors 10.

(14) Due to the shown embodiment it is possible to enhance the capacity to about 3000 ml. Further, it is possible that the capacity to further enhance the capacity by a sequence of inventive containers 1 connected in the same way, for example by a sequence of three or more containers 1 wherein connections between inlet openings 3 and outlet openings 4 are created.

(15) The shown and described embodiments of the figures are only illustrative for the invention and are not limiting for the invention.
