Abstract

Anti-pressure point drain for the discharge of secretion (5) from human bodies (25) and wounds (26) by means of a sheath (23) encased labyrinth (22), by applying a vacuum (27), characterized in that the anti-Druckstellendrain (1) having a drainage length (3) provided with perforations (6) and marked with a placement length (4) without perforations by end mark (7), placement mark (8) and initial placement (9), connected to a drain tube (10) is pulled through the tissue of the wound (26) by means of a red needle (12) in the drain tube (10), so that the placement length (4) outside each pressure point layer (17) is only connected to connecting elements to avoid pressure points on the body (25).

Description

The invention relates to an anti-pressure point drain for the suction of wound exudate from a wound filling, which can be used for various forms of wound treatment, but in particular for the vacuum wound treatment of large and deep wounds for the suction of wound secretions.

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 for laying the above described means time, this approach also requires a 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, other relatively complicated supplementary supports and, as a rule, bell-shaped seals of 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 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 extraction of wound secretions from body cavities, such. In EP 1 764 127 A1 described.

Furthermore, in the EP 2008/003251 a flat drainage with a drainage tail and in the GB 20 2011 104 078.3 described a labyrinth drainage.

The use of round, perforated drainage hoses in wounds as well as the placement by means of needle are known for many applications. These drains are made of flexible plastics and silicone with perforations and applied.

The present invention has for its object to provide a drainage agent, which without much manual skill by the surgeon accurately to the relevant wound, especially a large deep wound, which u. a. is intended for vacuum wound treatment, is customizable, requires no complicated fixations when laying in the wound area and in particular allows easy sealability in the context of a vacuum wound treatment. At the same time, the device according to the invention is intended to bring about a more effective drainage effect than is possible with drainages known from the prior art. In particular, the proposed device should also enable an improved and more bearable for the patient vacuum wound treatment of large open wounds and ensure a significantly increased comfort without pressure points. An important task of the device according to the invention is to optimally dissipate the wound secretion through a labyrinth and to thereby form no pressure points in the initial and longitudinal regions.

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, soft, flat labyrinth material z. B. is applied with a flow mat as a flat drain.

The essence of the invention further consists in that a very flexible, soft, flat labyrinth material is used as a flow mat with labyrinth-like paths with a drainage area and a lying area to avoid pressure points for the patient and can be placed by means of redonnadel.

The invention is designed so that the first and second layers are spaced apart even under the influence of negative pressure, that labyrinth-like paths are formed between, on the flow mat cohesively applied means, and the one layer in the drainage area 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 at least on a layer having a secretion drainage port, e.g. B. drain hose formed.

The invention will be described in more detail below with reference to several different embodiments.

The 1 shows the device according to the invention as an anti-pressure point drain ( 1 ). By designing the total length in drainage length ( 3 ) and placement length ( 4 ), the possibility exists in the region of the pressure point position ( 17 ) do not place pressure points or hoses causing pressure points. The area of the drainage length ( 3 ) is equipped with perforations ( 6 ) Mistake. The secretion is as secretory flow ( 5 ). When placing the drain ( 1 ) is marked by endmarking ( 7 ), Placement Tag ( 8th ) and initial placement ( 9 ) the safety, the drainage area ( 3 ) should not be placed outside the wound exit. With the help of a Redonnadel ( 12 ), which in the Redonnadelaufnahme ( 11 ) of the drain hose ( 10 ), the anti-pressure drain ( 1 ) via the feeder ( 13 ) pulled through the tissue and fixed accordingly. The fixation takes place with the help of a sealing washer ( 18 ) after removing the protective film ( 20 ) with a pull tab ( 21 ) and exposed adhesive disk ( 19 ). By applying one in width ( 2 ) the drain hose ( 10 ) adapted labyrinthdrains ( 1 ) with a very flat, flexible maze ( 22 ) is gem. Placement length ( 4 ) every pressure point in the pressure point layer ( 17 ) avoided. The application of Labrinthdrain leads the secretion ( 5 ) optimally. Furthermore, due to the very low drainage height ( 24 ) and by the in the shell ( 23 ) inserted labyrinth ( 22 ) the risk of scrapping in the perforations ( 6 ) ingrown tissue greatly reduced. When pulling out the drain no major pain occurs.

The 2 shows another application of the Anti-Druckstellendrains ( 1 ) on. It becomes a semi-shaped embedding ( 14 ) formed in the drain tube ( 10 ) and by means of attachment ( 15 ) is connected. The Redonnadel ( 12 ) in the drain hose ( 10 ) and the drain ( 1 ) pulled through the fabric as described. Then by means of cutting ( 16 ) the Redonnadel ( 12 ) and the drain hose ( 10 ) away. With optimal sealing of the attachment ( 15 ), the drain hose ( 10 ) with cut ( 16 ) also serve as a drain hose.

The application of the Anti-Druckstellenendrains ( 1 ) show the 3 , The anti-pressure drain ( 1 ) is up to the placement mark ( 8th ) in the body ( 25 ). The sealing disc ( 18 ) is with the adhesive disk ( 19 ) on the body ( 25 ) attached. The placement length ( 4 ) exceeds the pressure point position ( 17 ), so that no pressure points arise when placed by fasteners or round hoses.
