Abstract

The invention relates to a container for drainage of fluids or wound secretion, comprising an inlet opening to connect with a drainage line and an outlet opening for releasing waste air accumulated inside the container during drainage, which is characterized in that the container is pre-evacuated, and the outlet opening is sealable, so that the container is transferable in a first and in a second operating condition, wherein in the first operating condition the outlet opening is sealed, so that a suction can be achieved at the inlet opening caused by the vacuum inside the container, and in the second operating condition the outlet opening is opened, so that air can enter the container through the outlet opening and neutralize the vacuum present inside the container.

Claims (23)

1. A container for drainage of fluid and/or wound secretion, comprising:

an inlet opening to connect with a drainage line, and

an outlet opening to release waste air accumulated inside the container during drainage,

wherein the container is pre-evacuated, and is rigid as not to change form when pre-evacuated,

wherein the outlet opening is sealable, such that the container is transferable in a first operating condition and in a second operating condition,

wherein, in the first operating condition, the outlet opening is sealed, such that a suction is achievable at the inlet opening by a vacuum inside the container, and

wherein, in the second operating condition, the outlet opening is opened, such that air is enterable into the container through the outlet opening which neutralizes the vacuum inside the container, whereby drainage of fluid and/or wound secretion is startable according to a vacuum drainage and afterwards is continuable as gravity drainage,

wherein the outlet opening comprises a first tubular element, which is at least one of clampable or pinchable to seal the outlet opening,

wherein the outlet opening comprises a filter, which is configured to provide a vent which is operable for at least one of air to release from the container or for air to enter into the container,

wherein the filter is gas permeable and liquid impermeable; and

wherein the container is pre-evacuated in a range of 40,000 Pascal to 98,000 Pascal.

2. The container according to claim 1 , wherein the first tubular element is clampable or pinchable by a clamping device to seal the outlet opening.

3. The container according to claim 2 , wherein the clamping device comprises a slide-clamp.

4. The container according to claim 1 , wherein the filter is permeable to air and impermeable to the drainage fluid and/or the wound secretion.

5. The container according to claim 1 , wherein the inlet opening is sealable.

6. The container according to claim 1 , wherein the inlet opening comprises a second tubular element, wherein the second tubular element is at least one of clampable or pinchable to seal the inlet opening.

7. The container according to claim 6 , wherein the second tubular element of the inlet opening is clampable or pinchable by a clamping device to seal the inlet opening.

8. The container according to claim 7 , wherein the clamping device comprises a slide-clamp.

9. The container according to claim 1 , wherein the container has a capacity in a range of about 400 ml to about 3000 ml.

10. The container according to claim 1 , wherein the container comprises a bottle and a bottle cap.

11. The container according to claim 1 , wherein the container is formed of plastic.

12. The container according to claim 11 , wherein the plastic is a transparent plastic.

13. The container according to claim 11 , wherein the plastic is a rigid plastic.
