Abstract

A water trap (1) for a breathing tube (2) includes a collection tank (3) for water of condensation and at least one device (4) for attaching the collection tank (3) to the breathing tube (2). The attachment is such that the water of condensation can be drawn off from the breathing tube (2) at any desired point of the breathing tube (2). The water trap (1) has at least one device (5) for preparing at least one opening in the breathing tube (2). The water trap (1) is manufactured at a low cost and makes safer and more reliable handling possible.

Claims

1. A water trap for a breathing tube, the water trap comprising:

a collection tank for collection of water of condensation;

an attaching means for attaching said collection tank to the breathing tube; and

an opening preparation device for preparing at least one opening in the breathing tube.

2. A water trap in accordance with claim 1, wherein said opening preparation device prepares an opening in the breathing tube by one or more of machining and/or cutting and/or punching and/or by removing material and/or by piercing.

3. A water trap in accordance with claim 1, wherein said opening preparation device comprises at least one of a mandrel and blade and mandrel with a duct for passing through the water of condensation.

4. A water trap in accordance with claim 1, wherein said attaching means provides one of a positive-locking attachment, attachment in substance and a nonpositive attachment of said collection tank to said breathing tube.

5. A water trap in accordance with claim 4, wherein said attaching means comprises a clamp and/or clip.

6. A water trap in accordance with claim 5, wherein said attaching means comprises:

two half shells of a U-shaped or V-shaped cross section; and

a fixing means connecting said two half shells to one another, the breathing tube being attached between the two half shells with the two half shells connected to one another.

7. A water trap in accordance with claim 6, wherein said fixing means comprises a snap-in and/or locking mechanism.

8. A water trap in accordance with claim 6, wherein an external diameter or outer circumference of the breathing tube is larger than an internal diameter or inner circumference of the clamp or clip or two half shells prior to the attachment, so that the breathing tube is clamped within the clamp or clip or said two half shells in a nonpositive manner by means of an elastic deformation of the breathing tube during the attachment of the breathing tube.

9. A water trap in accordance with claim 6, wherein the clamp or clip or at least one half shell has ribs or webs on an inner surface thereof for positive-locking engagement with tangential recesses located on an outer surface of the breathing tube.

10. A water trap in accordance with claim 1, wherein the water trap has a sealing element for sealing a fluid-carrying connection from said breathing tube to said collection tank against the environment.

11. A respiration system comprising:

a respirator for artificial respiration of a patient;

at least one breathing tube for at least one of inspiration and expiration;

a mouthpiece; and

a water trap comprising a collection tank for collection of water of condensation, an attaching means for attaching said collection tank to the breathing tube and an opening preparation device for preparing at least one opening in the breathing tube.

12. A water trap in accordance with claim 11, wherein said opening preparation device prepares an opening in the breathing tube by one or more of machining and/or cutting and/or punching and/or by removing material and/or by piercing.

13. A respiration system in accordance with claim 11, wherein said opening preparation device comprises at least one of a mandrel and blade and mandrel with a duct for passing through the water of condensation.

14. A respiration system in accordance with claim 11, wherein said attaching means provides one of a positive-locking attachment, attachment in substance and a nonpositive attachment of said collection tank to said breathing tube.

15. A respiration system in accordance with claim 14, wherein said attaching means comprises a clamp and/or clip.

16. A respiration system in accordance with claim 15, wherein said attaching means comprises:

two half shells of a U-shaped or V-shaped cross section; and

a fixing means connecting said two half shells to one another, the breathing tube being attached between the two half shells with the two half shells connected to one another.

17. A respiration system in accordance with claim 16, wherein an external diameter or outer circumference of the breathing tube is larger than an internal diameter or inner circumference of the clamp or clip or two half shells prior to the attachment, so that the breathing tube is clamped within the clamp or clip or said two half shells in a nonpositive manner by means of an elastic deformation of the breathing tube during the attachment of breathing tube.

18. A respiration system in accordance with claim 16, wherein the clamp or clip or at least one half shell has ribs or webs on an inner surface thereof for positive-locking engagement with tangential recesses located on an outer surface of the breathing tube.

19. A respiration system in accordance with claim 11, wherein the water trap has a sealing element for sealing a fluid-carrying connection from said breathing tube to said collection tank against the environment.

20. A process for providing a breathing tube with a water trap, the process comprising the steps of:

providing a breathing tube;

providing a collection tank for water of condensation;

providing an attachment means for attaching the collection tank to the breathing tube;

attaching the collection tank to the breathing tube with said attaching means;

preparing an opening in breathing tube and establishing a water-carrying connection from an interior of said breathing tube into the collection tank for sending water of condensation from the interior of breathing tube into said collection tank.

21. A process in accordance with claim 20, wherein the opening is prepared in the breathing tube by machining and/or cutting and/or punching and/or by removing material and/or piercing.

22. A process in accordance with claim 20, wherein the opening is prepared in the breathing tube by a blade and/or a mandrel.

23. A process in accordance with claim 20, further comprising a seal structure with a valve for sealing the opening in the breathing tube to prevent fluid flow from inside the breathing tube to the outside of the breathing tube when the collection tank is removed from the breathing tube, whereby no air flows from the breathing tube into the environment and/or vice versa.
