Description

The The invention relates to a device for removing wound secretions.

The Device is especially for the permanent removal of wound secretions from body cavities suitable.

wound secretions are predominantly watery secretions that can escape from a wound due to an injury.

The Composition of wound secretions, especially from the intercellular spaces can be fed, can vary greatly. It contains mainly admixtures serum proteins and traces of blood components. At a Infection also increased wound secretions Amounts of macrophages intended to eliminate the microorganisms. This can be associated with the formation of pus. Will the wound secretion not from an inflamed body cavity removed, this leads to the formation of abscesses.

To the Remove wound secretions from body cavities used in practice various devices.

Known is the use of drainage tubes, gauze or smaller sponges.

The However, known devices are associated with disadvantages.

Of the Use of drainage hoses leads very fast for the formation of channels in the body cavity. That in the body cavity and arising Wound secretion is thus sucked only when it is near of such a channel. Otherwise it remains but in the body cavity. drainage tubes are therefore permanent and as complete as possible Suction of wound secretions not suitable. Drainage hoses exist mostly made of silicone.

abdominal swabs are usually rectangular layers of cotton or a similar soft and absorbent material that enters the body cavity be introduced. The absorbent material takes that in the body cavity or emerging wound secretions on. Naturally, however, such a belly cloth has only a limited capacity to absorb body fluids. For this reason, it is necessary to adjust the abdomen after a certain Remove time from the body cavity and through to replace a new one. This exchange of the abdominal tissues is each with an operative intervention and a permanent one Anesthesia associated with the physical and psychological state of the Patients can affect adversely. moreover the practitioner who puts a belly-cloth into a body cavity to ensure that this is replaced before whose capacity is actually exhausted. For this reason, the therapist has speculations about it to ask when this will be the case.

sponges are too rude and inflexible to put them in body cavities to contribute. Because the sponges are rigid and they are too small, they can only in small body cavities be used. Due to the nature of the sponges is with damage to organ surfaces to count. The unabsorbed sections of the body cavity stick together and can ignite. you are therefore not for aspirating wound secretions from body cavities or very limited.

sponges are therefore mainly used to treat external Wounds used. For this, the sponge is applied to the wound, the wound and the sponge on it with a vacuum foil covered and the sponge connected to a drainage hose, over a negative pressure between the top of the outer Wound and the bottom of the vacuum film can be generated. The Wound secretion can be sucked out of the open wound.

Of the Sponge can by cutting to the wound size be adjusted. However, the sponge does not just have to cover the wound, but also have a certain thickness over the wound, order for an even distribution of the Negative pressure to provide over the wound surface.

Especially However, a disadvantage is the risk that the sponge clogged, so that the negative pressure is not evenly over the wound surface can be distributed.

includes.

Also this invention has all the disadvantages such as risk of clogging or organ injury, as with the use of sponges occur.

in the GB 20 2009 005 780.1 [0002] There is described a device for removing secretions from body cavities in which two superimposed elastic, porous, soft labyrinth materials discharge fluid out of the body to the outside.

Out Thus, no system is known in the prior art that a permanent and complete removal of wound secretions from body cavities allows, without constant surgical intervention required are. In particular there is no system with which the entire abdominal cavity, including all organ spaces, can be sucked off without the organs and their surface to harm.

task The invention is to the disadvantages of the prior art remove. In particular, a device is to be specified which on the one hand a permanent and complete removal of wound secretions from the entire body cavity, without damaging the organs, and on the other hand, a simple Adaptation of the device to the size of the body cavity allows.

These The object is solved by the features of the claims. Expedient embodiments of the invention result arising from the features of the remaining claims.

• – zumindest zwei auf einer Labyrinthmasse liegende Lagen eines Feuchtigkeitsdurchlässigen, porösen, elastischen, weichen Stoffes und
• – zumindest einer Drainageableitung zur Vakuumquelle sowie zum Sekretauffangbehälter.

According to the invention, a device for removing wound secretions from body cavities is provided, comprising

• - At least two layers lying on a labyrinth mass of a moisture-permeable, porous, elastic, soft material and
• - At least one drainage discharge to the vacuum source and the secretion collecting container.

The Layers of the porous, elastic, soft moisture transmitting end Stoffes are cohesive with the labyrinth or drain connected and in the body cavity or in the wound inserted.

The Layers are structured to make the secretion optimal to the labyrinth or let through to the drain. They are antimicrobially coated.

Become the layers with the labyrinth or drain into the body cavity introduced, so are the gauzy outsides of the two layers each on the insides of the body cavity or on various organs gently, so that there forming wound secretions through the gauzy structure over the labyrinth or the Drain from the body cavity to the outside can drain away.

The gauzy layers are cohesive with the labyrinth or drain connected.

Under a body cavity becomes here a cavity of the human one or animal body understood. Such cavities are usually lined with an epithelium or mesothelium.

The Device according to the invention can, for example for removing wound secretions from the peritoneal cavity (Cavitas peritonealis), pleural cavity (Cavitas pleuralis) or joint cavities (Cavitas articularis).

The Device according to the invention allows For the first time, wound exudate permanently from a body orifice suck. Unlike the drainage hoses of the The prior art, the channel formation by the introduction of the Prevents layers. The layers of the gauze structure as well as the elastic, porous labyrinth masses are flexible and allow due to the labyrinth design a longer-term, continuous and organ-friendly suction of wound secretions from body cavities. The Danger of injury to organs is largely due to the gauze structure locked out.

The Applied layers are preferably made of a gauze structure with consist of large mesh.

The Labyrinth should preferably be made of a PE bubble wrap with air knobs, Diameter 8-10 mm, consist.
