Abstract

The invention relates to a device for connecting multi-lumen lines for the medical field, in particular for wound care in the field of vacuum therapy, having a preferably one-piece basic body, designed for tight and preferably releasable connection of at least two line lumens, wherein the basic body, for furnishing a distributor chamber for at least one, preferably two, three, or more lumens, opening into it, of the connected line and preferably at least one channel for removing a fluid from and introducing it into the distributor chamber, and when the line is connected, the distributor chamber is sealed off in fluid-tight fashion from at least one line lumen in such a way that a fluid exchange between the distributor chamber and this line lumen is prevented.

Claims

exact text as granted — not AI-modified
1 - 18 . (canceled) 
     
     
         19 . A connection device for a multi-lumen tube sheath having a central lumen and at least one additional lumen radially offset from the central lumen, the connection device comprising:
 a central collar defining a distributor chamber;   at least one connection fitting extending coaxially from the central collar;   at least one chamber bushing extending coaxially from the central collar and spaced apart from the connection fitting to form an annular gap between the connection fitting and the chamber bushing; and   wherein when a multi-lumen tube sheath is introduced into the annular gap, the connection fitting is inserted into the central lumen, the at least one additional lumen is in communication with the distributor chamber, and the central lumen and the at least one additional lumen are sealed off from one another in a fluid-tight fashion.   
     
     
         20 . The device of  claim 19  further comprising a stop that limits the introduction of the tube sheath into the annular gap. 
     
     
         21 . The device of  claim 20  wherein the stop is a radial shoulder on the connection fitting. 
     
     
         22 . The device of  claim 20  further comprising a window in the central collar through which visual monitoring of the contact of the tube sheath end with the stop is enabled. 
     
     
         23 . The device of  claim 19  further comprising a sealing device in the annular gap. 
     
     
         24 . The device of  claim 23  wherein the sealing device is a sealing shell received in the annular gap, the sealing shell having at least one sealing lamella surrounding the chamber bushing axis and coming into contact with the outer boundary face of the tube sheath when it is introduced. 
     
     
         25 . The device of  claim 24  wherein the sealing shell further comprises an encompassing bead and the chamber bushing further comprises a radially inner indention, wherein a ring snap connection is formed between the sealing shell and the chamber bushing. 
     
     
         26 . The device of  claim 25  wherein the encompassing bead has at least one opening whereby the encompassing bead does not completely surround the sealing shell. 
     
     
         27 . The device of  claim 23 , wherein the sealing device comprises a polygonal lamella seal. 
     
     
         28 . The device of  claim 23 , wherein the sealing device comprises a round lamella. 
     
     
         29 . The device of  claim 23 , wherein the sealing device is a face-end seal. 
     
     
         30 . The device of  claim 23 , wherein the sealing device is an o-ring. 
     
     
         31 . The device of  claim 23 , wherein the sealing device is a radial shaft seal. 
     
     
         32 . The device of  claim 19  further comprising a securing device that is adjustable between a release position, which enables the introduction of a multi-lumen tube into the annular gap, and a securing position, which secures a multi-lumen tube within the connection device. 
     
     
         33 . The device of  claim 32  wherein the securing device comprises a clamping bushing extending coaxially to the chamber bushing. 
     
     
         34 . The device of  claim 33  further comprising at least two clamping tongues extending from the chamber bushing, wherein the clamping tongues are offset radially inward when the clamping bushing is moved from the release position to the securing position. 
     
     
         35 . A connection device for connecting two multi-lumen tube sheaths each having a central lumen and at least one additional lumen radially offset from the central lumen, the connection device comprising:
 a central collar defining a distributor chamber;   a pair of connection fittings extending coaxially and in opposite directions from the central collar, the connection fittings defining a continuous bore;   a pair of chamber bushings extending coaxially from the central collar and spaced apart from the connection fittings to form an annular gap between each of the connection fittings and the chamber bushings; and   wherein when two tube sheaths are introduced into the annular gaps, the connection fittings are inserted into the central lumens of the tube sheaths, the at least one additional lumen of each sheath is in communication with the distributor chamber, and the central lumens and the at least one additional lumens are sealed off from one another in a fluid-tight fashion.   
     
     
         36 . The connection device of  claim 35 , wherein the length of one of the connection fittings is different from the length of the other connection fitting, whereby the forces required to release the tube sheathes from the connection fittings are unequal. 
     
     
         37 . A device for connecting multi-lumen lines for the medical field, in particular for wound care in the field of vacuum therapy, the device comprising:
 a one-piece basic body designed for tight and releasable connection of at least two multi-lumen lines, the basic body furnishing at least one distributor chamber for at least one line lumen to open into and a channel for removing a fluid from or introducing a fluid to the distributor chamber;   wherein when a multi-lumen line is connected to the basic-body, the distributor chamber is sealed off in fluid-tight fashion from at least one line lumen such that fluid exchange between the distributor chamber and the at least one line lumen is prevented.   
     
     
         38 . The device of  claim 37  wherein the basic body furnishes two or more distributor chambers, of which at least two are connected with each other via at least one channel.
