Abstract

Anti-pressure point rinsing drain (1) for suctioning wound exudate (18) from wounds (11), characterized in that a flushing drawer (12) provided with needle perforations (15), which is enveloped by the inner labyrinth (3), liquid (16 ) by means of pressure through the labyrinth (3) and the perforations (2) into the wound (11) passes.

Description

The anti-pressure point rinse drainer is designed in its functional length so that it does not create pressure points when placed in the wound on the body due to its flat, soft construction with a flexible labyrinth. The combination with vacuum secretion can be sucked.

The wound irrigation wets the wound with liquid and activates it for a better healing.

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 considerable skill of the wound care practitioner, 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 T2 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-area 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 covering 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 suction 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 application of drainage without rinse is required in the first few days of placement of the anti-pressure point pulse drain in the wound area when the wound is heavily wet. Otherwise, it must be kept moist with the help of the Spätldrains, so that there can settle healing cells.

Changing the anti-pressure point rinsing trainer depends on the stage of the depth and condition of the wound.

The present invention is based on the object by means of suction vacuum secretions and at the same time by supplying liquids, whereby a moist wound milieu is achieved, to create the basis for a better wound healing.

The peculiarity here is that an anti-pressure points Spülldrain was formed, which is in the application length with its perforations in the wound area and in the functional length outside the wound area.

The formation of the drain with a flexible labyrinth material shows that in the functional length no pressure point problems arise on the body and the secretion can be sucked unhindered by vacuum.

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 very flexible labyrinth material is formed as a film material with labyrinthine paths through connections and when laying two layers on each other a plane is provided, the first and second layer spaced from each other even under the influence of negative pressure, that between , on the film cohesively applied funds, labyrinthine paths are formed and the one layer is provided at least with perforations.

In a preferred embodiment, the first and second layers, as well as the spacing plane including the spacing means, are formed at least on a layer having a secretion drainage opening.

In a further embodiment of the invention, which is particularly preferred for practical use, the first and second layers are made of an optically translucent, flexible film material, at least in the wound area to be detected by them; the compounds conduct the wound secretion to the suction site.

This labyrinth device is internally formed with a rinsing drain.

The 1 describes an anti-pressure point flush drain ( 1 ), which consists of a transparent, with perforations ( 2 ) provided, flexible sheath exists.

In the drain ( 1 ) is a special flush drain ( 12 ) with needle perforations ( 15 ).

Through this flush drain ( 12 ) can be liquid ( 16 ) in the wound ( 11 ) be transported.

The rinsing drain ( 12 ) is with a labyrinth ( 3 ) encased in vacuum ( 17 ) through the perforations ( 2 ) Wound secretions ( 18 ) from the wound ( 11 ) sucks.

The anti-pressure point flush drain ( 1 ) is equipped with a suction hose ( 10 ) for the labyrinth ( 3 ) and with a flushing hose ( 13 ) for the rinsing drain ( 12 ) equipped.

In the Spüldrain ( 12 ), a spacer film was used to prevent collapse ( 7 ).

In the application process, the anti-pressure point flush drain ( 1 ) to the mark ( 4 ) with the wound length ( 6 ) in the wound ( 11 ).

By using a flexible drainage shell and a flexible labyrinth ( 3 ) occur when the function length ( 5 ) on the skin ( 20 ) no pressure points.

The process vacuum ( 17 ) for wound secretion suction and rinsing of the wound ( 11 ) by means of rinsing liquid ( 19 ) can be performed depending on the required indication.

In special cases, the closure ( 14 ) are removed. In these cases, rinsing fluid ( 19 ) at the front and through the flushing opening ( 8th ) flow. The regulation is carried out by hose clamps ( 9 ).

The 2 shows a section through the Antidruckstellen-Spüldrain ( 1 ).

On average AA are the perforation ( 2 ) around the circumference of the flexible shell and the surrounding labyrinth ( 3 ) documented in the case.

The rinsing drain ( 12 ) is inside with a spacer film ( 7 ), which avoids collapse and the inflow of liquid ( 16 ).

Through the needle perforations ( 15 ), which are placed on the circumference of the rinsing drains, the liquid ( 16 ), preferably sterile saline solution, through the labyrinth ( 3 ) and the perforations ( 2 ) in the wound ( 11 ).

The 3 shows the application of the anti-pressure point rinsing machine ( 1 ) in the wound ( 11 ).

The drain ( 1 ) is up to the mark ( 4 ) visible in front of the skin ( 20 ) in the wound ( 11 ).

Through the perforation ( 2 ) the wound secretion ( 18 ) by means of vacuum ( 17 ) through the labyrinth ( 3 ), through the suction hose ( 10 ) from the wound ( 11 ) drawn.

During the flushing process, liquid ( 16 ), preferably sterile saline solution, into the flushing tube by means of a syringe ( 13 ).

The liquid ( 16 ) passes through the needle perforations ( 15 ), the maze ( 3 ) and the perforations ( 2 ) in the wound ( 11 ). The wound ( 11 ) can thus be kept moist, which contributes to a faster and better healing.

The wound length ( 6 ) with perforations ( 2 ) is placed only in the wound area.

The function length ( 5 ) is from the mark ( 4 ) so effective that on the skin ( 20 ) no pressure points arise.

The suction hose ( 10 ) and the flushing hose ( 13 ) act only outside the skin, eg in the back area.
