Abstract

Labyrinth drainage for the discharge and suction of wound exudate and body fluids from human or animal bodies, characterized in that a labyrinth (2) in a perforated, flexible sheath (1) formed with flap (3) and opening (4) is embedded and by means of a placement element as a rod (17) or spatula (21) can be placed by positioning in a quiver (14) in a tissue channel (22) to the wound site (25) by means of feed (24).

Description

The invention describes a labyrinth drainage, which is advanced by means of placement elements, such as a rod or spatula in a quiver, by advancing in a tissue channel to the wound site, so that wound exudate can be sucked.
The peculiarity of the invention is that the labyrinth material is tailored according to the indication and embedded in a perforated, flexible shell, which avoids a perforation of organs with the respective embedded labyrinth by their flexibility.

It is a common task in medicine to suck out wound fluids. In particular, in the case of deep, large and, in particular, infected surface wounds, the hitherto customary practice is to place a wound dressing which does not adhere to the tissue into the wound. On this wound dressing the physician brings a first layer of gauze, in which then by hand a drainage tube, partially wound several times, is applied and this covered again with a second layer of gauze and then the entire wound site is covered with a plaster. The end of the drainage tube is then subjected to a negative pressure, whereby the wound fluid can be sucked off.
In addition to the long time required to lay the above described means time, this approach also requires a considerable skill of the wound care physician, because during wound care all separately inserted device components are to be fixed, which often can not be accomplished by one person alone.

Another type of wound dressings, which were developed in particular for the vacuum wound treatment, is, for example, in DE 601 18 546 described.
The wound dressing described there requires, on the one hand, a relatively high manufacturing outlay and, on the other hand, is not readily adaptable to different wound sizes. In order to carry out a vacuum treatment, this solution requires, on the other hand, additional relatively complicated additional supports and, as a rule, bell-shaped seals on the wound, to which an external vacuum connection is attached.
Such, the skin surface far superior designs significantly restrict the freedom of movement of the patient and also generate unpleasant additional pressure loads.

The above-outlined treatment of such wounds under negative pressure is a method practiced for many years, which positively influences the healing of deep and large wounds by permanent wound stimulation. This type of vacuum wound treatment is, for example, in DE 694 25 881 T3 . DE 692 29 940 T2 and DE 692 24 847 T3 described in detail, which is why reference should be made here only.

In addition, there are a variety of other solutions, which should be listed here only as an example, because they concern more distant technical solutions.

That's how it is US 6,695,824 B2 a wound dressing cover for outer flat wounds consisting of two layers, the first layer being applied directly to the wound and the second layer having an outward-acting moisture barrier.
Between the layers mentioned several hose-like supply lines are provided which ensure a moisture supply to the wound.

For use in the context of wound treatment of deep, poorly healing wounds with the aid of the technique of vacuum wound treatment, however, the abovementioned wound dressing cover is not designed and also unsuitable, because a vacuum-tight lead-out of the sometimes multiple hoses from the wound area is practically impossible.
The same applies to a variety of devices for the extraction of wound secretions from body cavities, such as in EP 1 764 127 A1 described.

Furthermore, in the EP 2008/003251 a surface drainage with a derivative tail described.

The present invention is based on the object of providing a gentle, flexible, soft wound dressing which can suck secretions through a labyrinth by means of a vacuum from a wound, wetting the wound with weakly exuding wounds by injecting liquid, as well as faster and effective wound healing.
The object of the invention is solved by the characterizing features of claim 1.
Advantageous embodiments are the subject of the dependent claims.

The essence of the invention is that a labyrinth drainage can be placed in a perforated shell by means of rod or spatula, by contrast strips in the shell, optimally in deep, difficult to reach wound areas and after removal of rod or spatula, the shell in the wound area alone remains lying.
Thus, wound exudate can be aspirated through the perforation of the sheath and the labyrinth.
All subclaims are also part of the main claim.
The invention is further documented in the attached schematic drawings.

In the 6 is the shell ( 1 ) with labyrinth ( 2 ) with a quiver ( 14 ), in which the ball ( 16 ) of the rod ( 17 ) with handle ( 15 ) and by means of feed ( 24 ) through a tissue channel ( 22 ) to the wound site ( 25 ) is advanced. This achieves a wound-friendly placement according to the existing indication.

The 7 shows the rectangular, area-like design of the shell ( 1 ) with a wide quiver ( 14 ), one with a strand length ( 19 ) trained strand ( 20 ), a labyrinth ( 2 ) and a suction hose ( 10 ).
With the help of a flat spatula ( 21 ) by inserting the spatula ( 21 ) in the quiver ( 14 ) by feed ( 24 ) the placement at the wound site ( 25 ). The spatula ( 21 ) is reached after reaching the desired wound position from the shell ( 1 ) away.

The application of the invention is in the 8th shown.
The case ( 1 ) with embedded labyrinth ( 2 ) is through the rod ( 17 ), whose ball ( 16 ) in the quiver ( 14 ) is inserted, with feed ( 24 ) through the tissue channel ( 22 ) at the wound site ( 25 ).
After placement, the staff ( 17 ) from the quiver ( 14 ) and from the tissue ( 23 ) pulled out.
Wound exudate ( 28 ) can through the perforation ( 9 ), the maze ( 2 ) and the suction hose ( 10 ) are sucked off.
The in quiver ( 14 ) incorporated procedure ( 26 ) allows the drainage of liquid ( 27 ).

The 9 shows the insert of the shell ( 1 ) with labyrinth ( 2 ) in the hollow rod ( 17 ), wherein the rod end in the circumferential Quiver ( 14 ) is placed.
After insertion of the rod ( 17 ) with inner shell ( 1 ) and labyrinth ( 2 ) is reached when reaching the wound site ( 25 ), controllable by the contrast strip ( 13 ) in the bar ( 17 ), the rod ( 17 ) from the tissue ( 23 ), whereby the edge ( 29 ) of the quiver ( 14 ) acts as a resistance and the shell ( 1 ) in the tissue ( 23 ) after removal of the rod ( 17 ) remains placed.
