System for drainage of fluids or wound secretion

1. A system for drainage of fluid secretion from a body and/or a tissue opening of a human or animal body comprising:

a bag reservoir to collect the fluid secretion, wherein the bag reservoir has an upper inlet opening and a lower outlet opening,

a pre-evacuated container having an inlet opening, wherein the inlet opening of the pre- evacuated container is connected to the lower outlet opening of the bag reservoir,

wherein, during an operation of the system, the bag reservoir and the pre-evacuated container are arranged in fluid communication such that drainage is performed in a presence of suction provided by a vacuum of the pre-evacuated container over the bag reservoir,

wherein the pre-evacuated container is disconnectable from the lower outlet opening of the bag reservoir during the drainage,

wherein the pre-evacuated container is pre-evacuated prior to being connected to the lower outlet opening of the bag reservoir,

wherein the lower outlet opening of the bag reservoir is sealable by a sealing device, and

wherein, when the lower outlet opening of the bag reservoir is sealed by the sealing device, the fluid secretion in the bag reservoir cannot exit from the lower outlet opening.

2. The system according to claim 1 , wherein the bag reservoir is made of a flexible material.

3. The system according to claim 2 , wherein the bag reservoir is made of plastic.

4. The system according to claim 1 , wherein, during the operation of the system, the bag reservoir and pre-evacuated container are arranged in fluid communication such that the drainage is initiatable or achievable by the suction provided by the vacuum of the pre-evacuated container over the bag reservoir.

5. The system according to claim 1 , wherein a surface of an inner wall of the bag reservoir is profiled.

6. The system according to claim 1 , wherein the bag reservoir has a capacity in a range of about 500 ml to about 5000 ml.

7. The system according to claim 1 , wherein a tubular outlet is located at the lower outlet opening of the bag reservoir.

8. The system according to claim 7 , wherein the lower outlet opening and the tubular outlet are built integrally.

9. The system according to claim 1 , wherein the sealing device is a clamp device.

10. The system according to claim 7 , wherein the lower outlet opening and/or the tubular outlet of the bag reservoir are clampable by a clamp device.

11. The system according to claim 10 , wherein the clamp device comprises a slide clamp.

12. The system according to claim 7 , wherein the lower outlet opening and/or the tubular outlet of the bag reservoir includes a vent to seal the lower outlet opening and/or the tubular outlet.

13. The system according to claim 12 , wherein the vent comprises a check valve.

14. The system according to claim 1 , wherein a drainage line is located at the upper inlet opening of the bag reservoir for connecting to the body and/or tissue opening of the human or animal body.

15. The system according to claim 1 , wherein the bag reservoir and the pre-evacuated container are pre-connected.

16. The system according to claim 1 , wherein the upper inlet opening of the bag reservoir has a backflow protection, such that the fluid secretion in the bag reservoir cannot exit from the upper inlet opening of the bag reservoir.

17. The system according to claim 1 , wherein the bag reservoir and/or the pre-evacuated container have a holder for hanging and/or mounting.

18. A method for drainage of fluid secretion from a body and/or a tissue opening of a human or animal body, comprising:

obtaining a system for drainage of the fluid secretion from a body and/or a tissue opening of a human or animal body comprising

a bag reservoir to collect the fluid secretion, wherein the bag reservoir has an upper inlet opening and a lower outlet opening,

a pre-evacuated container having an inlet opening, wherein the inlet opening of the pre-evacuated container is connected to the lower outlet opening of the bag reservoir,

wherein, during an operation of the system, the bag reservoir and the pre-evacuated container are arranged in fluid communication such that drainage is performed in a presence of suction provided by a vacuum of the pre-evacuated container over the bag reservoir,

wherein the pre-evacuated container is disconnectable from the lower outlet opening of the bag reservoir during the drainage,

wherein the pre-evacuated container is pre-evacuated prior to being connected to the lower outlet opening of the bag reservoir,

wherein the lower outlet opening of the bag reservoir is sealable by a sealing device, and

wherein, when the lower outlet opening of the bag reservoir is sealed by the sealing device, the fluid secretion in the bag reservoir cannot exit from the lower outlet opening, providing an initial suction at the body and/or the tissue opening of the human or the animal body using the pre-evacuated container, wherein the initial suction of the pre-evacuated container is transferred over the bag reservoir arranged between the body and/or the tissue opening and the pre-evacuated container; and

disconnecting or clamping off the pre-evacuated container from the bag reservoir after creation of the initial suction, such that afterwards the fluid secretion is collected inside the bag reservoir by a gravity drainage.

19. The system according to claim 1 , wherein the fluid secretion comprises a wound secretion.

20. The system according to claim 1 , wherein the pre-evacuated container is connectable to and disconnectable from the lower outlet opening via a connectable/disconnectable connector, and wherein the sealing device is disposed upstream of the connector.
