Abstract

The present invention relates to a tube covering for a tubing system, especially for monitoring a vascular access for an extracorporeal blood treatment. The inventive tube covering has at least one flexible bottom layer on which a section of the at least one tubing and/or a connection system of at least one tubing may be placed and has at least one flexible top layer for covering the section of the at least one tubing and/or the connection system of the at least one tubing. The bottom layer and the top layer are joined to one another such that they form an openable wrapping for inserting the section of the at least one tubing and/or the connection system of the at least one tubing, fastening means for detachably joining the top layer and the bottom layer being provided on the top layer and bottom layer.

First claim

1 - 25 . (canceled)

26 . A sterile tube covering for a medical tubing system for monitoring the vascular access during extracorporeal blood treatment with which a fluid is at least one of supplied to a patient or removed from a patient via at least one tubing, the sterile tube covering comprising:
at least one flexible bottom layer on which at least one of a section of the at least one tubing or a connection system of the at least one tubing is placed; at least one flexible top layer configured to cover at least one of the section of the at least one tubing or the connection system of the at least one tubing, wherein the bottom layer and the top layer are joined to one another such that they form an openable wrapping configured for insertion of the section of at least one of the section of the at least one tubing or the connection system of the at least one tubing; and a fastening device provided on the top layer and bottom layer, the fastening device configured to detachably join the top layer and the bottom layer.

27 . The tube covering according to claim 26 , wherein:
the top layer and the bottom layer form a single material piece, and a bottom surface of the top layer lies on a top surface of the bottom layer when the wrapping is folded closed.

28 . The tube covering according to claim 26 , wherein:
the top layer and the bottom layer are separate components which form a material piece, and a bottom surface of the top layer lies on a top surface of the bottom layer when the wrapping is folded closed.

29 . The tube covering according to claim 26 , wherein the bottom layer has an absorbent material configured to absorb a fluid escaping from at least one of the section of the at least one tubing or the connection system of the at least one tubing.

30 . The tube covering according to claim 26 , wherein the bottom layer is a composite material, the composite material including an absorbent material and a film, wherein the film is arranged on an exterior side of the tube covering and the absorbent material is arranged on an interior side of the tube covering.

31 . The tube covering according to claim 29 , wherein the absorbent material has a moisture sensor that is embodied as an electrically conducting structure.

32 . The tube covering according to claim 31 , wherein the absorbent material is a woven fabric having non-conducting warp threads, non-conducting weft threads, conducting warp threads, and conducting weft threads that are arranged such that the electrically conducting structure is embodied in the woven fabric.

33 . The tube covering according to claim 31 , wherein the tube covering further comprises:
connecting contacts configured to electrically contact the moisture sensor, the connecting contacts disposed at an end of a longitudinal section that is connected to the top layer or bottom layer.

34 . The tube covering according to claim 31 , wherein the top layer is a composite material, the composite material including an absorbent material and a film, wherein the film is arranged on an exterior side of the tube covering and the absorbent material is arranged on an interior side of the tube covering.

35 . The tube covering according to claim 34 , wherein the film is a transparent film such as LDPE.

36 . The tube covering according to claim 26 , wherein the fastening device has on at least one of a top surface of the bottom layer or on a bottom surface of the top layer at least one surface provided with an adhesive or adhesion layer such as a strip provided with the adhesive or the adhesion layer.

37 . The tube covering according to claim 26 , wherein the fastening device has at least one fastening tab provided on the top layer configured for insertion into a cut-out provided on the bottom layer.

38 . The tube covering according to claim 26 , wherein the fastening device has at least one first closure part with a button provided on the top layer and a second closure part with a depression provided on the bottom layer such that the button is configured to snap into place in the depression.

39 . The tube covering according to claim 26 , wherein the fastening device has a fold provided on the bottom layer configured to receive and clamp the top layer.

40 . The tube covering according to claim 26 , wherein at least one of the top layer or the bottom layer has at least one notch configured to receive the section of the at least one tubing.

41 . The tube covering according to claim 40 , wherein the at least one notch has:
a slit configured to insert the tubing; and a cut-out configured to receive and clamp a section of the at least one tubing connecting thereto.

42 . The tube covering according to claim 26 , wherein the at least one tubing has an insert element having at least one clamp configured to attach the section of the at least one tubing by clamping.

43 . The tube covering according to claim 26 , further comprising:
a first wrapper and a second wrapper, the first wrapper and the second wrapper configured to join to one another with a connecting tab.

44 . The tube covering according to claim 43 , wherein the connecting tab is a composite material made of a textile material and a film.

45 . A method for producing a sterile tube covering for a medical tubing system, the tube covering having at least one flexible bottom layer on which at least one of a section of the at least one tubing or a connection system of the at least one tubing is placed, and having a flexible top layer for covering at least one of the section of the at least one tubing or the connection system of the at least one tubing, the method comprising:
providing a first material sheet for cutting first component pieces for the top layer; providing a second material sheet for cutting second component pieces for the bottom layer; applying material pieces made of an absorbent material to the second material sheet at a predetermined distance from one another; applying first fastening devices to the first material sheet at a predetermined distance from one another; applying second fastening devices to the second material sheet at a predetermined distance from one another; separating the first component pieces from the first material sheet and separating the second component pieces from the second material sheet; and joining the first and second component pieces to form a single material piece.

46 . The method according to claim 45 , wherein the material pieces have a moisture sensor embodied as an electrically conducting structure.

47 . The method according to claim 45 , wherein the first and second fastening devices are a hook and loop closure which includes at least one strip provided with an adhesive or adhesion layer.

48 . The method according to claim 45 , wherein the first and second material sheets are film sheets, wherein the first and second component pieces are welded to one another on one side.

49 . The method according to claim 45 , wherein the material pieces are folded such that a bottom surface of the top layer lies on a top surface of the bottom layer.

50 . The method according to claim 45 , wherein one of:
