Abstract

Anti-pressure point pulse drain (1) for discharging secretion (20) from a wound (22), characterized in that a pulse drain (4) in the anti-pressure point impulse drain (1) with a labyrinth (3) is covered by on and decongestant pressure impulses (6) improves wound healing and is sucked off by means of vacuum (7) secretion (20).

Description

The anti-pressure point impulse drain is designed in its functional length so that it generates no pressure points after placement in the wound by means of Redon needle or embedding in the wound on the body because of its flat, soft construction with a flexible labyrinth. The combination with vacuum secretion can be sucked. Through the incorporated impulse drain the wound is activated by increasing and decreasing pressure for a better healing. This is done by alternating pressure cycles in a sinusoidal curve in the lower and overpressure for better wound 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 present invention has for its object to provide a vacuum and pressure device that sucks wound secretion and achieved by a sinusoidal course of the cycle with increasing and decreasing underpressure and overpressure a better wound healing effect.

By the o.g. Device will be changing overpressure and negative pressure to contribute to a quick healing in case of injury.

The pressures are periodically built up and broken down, which leads to a deformation of the tissue and thus stimulates the metabolism and thus the healing.

The wound is equipped, for example, with a labyrinth drainage as a vacuum element, which generates a vacuum by means of a vacuum pump and sucks out secretions.

This negative pressure promotes the diffusion of nutrients and oxygen from the patient's blood into the wound. As a result, new tissue grows faster, the wound heals faster.

To this vacuum element, an overpressure device is placed, which, connected to a pressure pump, achieved by the vacuum device with the pressure device various pressure cycles in a sinusoidal course of the cycle with increasing and decreasing negative pressure and overpressure strengths a greater wound healing effect.

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 formed with a pulse tube.

This pulse tube is activated or deactivated by a pressure pump, which leads to an alternating pressure load on the labyrinth device and on the wound base. A cycle in the sinusoidal course of positive and negative pressure is thus possible.
