Translation of "Cavity wounds" in German

Furthermore, the response of vacuum therapy systems can be tested on different wound geometries and/or wound structures, such as, for example, large-area wounds as opposed to cavity wounds.

This is efficacious, in particular, when applied to organs that are naturally under negative pressure (organs in the thoracic cavity) or to wounds and wound cavities that are in contact with the thoracic cavity and which are physiologically under negative pressure as a consequence.

Furthermore, Intrasite Gel can be used in the treatment of granulating cavity wounds, radiation wounds and abrasions.

The inflamed tissue is also removed from the wound cavity.

They are preferably laid while still dry onto the wound or else wound cavities are filled with them.

In such cases, the wound cavity is directly irradiated after removal of the tumour.

In the intracavitary variant, the sponge element is introduced through the defect into an extraluminal wound cavity.

A suction flask of this kind is connected by means of a flexible tube to a perforated wound drainage tube, which in turn is introduced into a hermetically sealed wound cavity.

The negative pressure prevailing in the suction flask thus also acts in the wound cavity, so that wound secretions forming there can be sucked off into the flask.

The invention relates to a suction bottle for sucking out secretions from wound cavities, with an arrangement for checking the vacuum sealing off a pressure opening in the suction bottle, and with a connecting stub for a suction line.

For this purpose, a pre-evacuated suction bottle preferably equipped with a vacuum indicator is connected via a connecting tube with a perforated drainage tube which is inserted in the cavity of the wound, the latter being sealed airtight.

Description in DE-GM (German Utility Model) No. 73 36 232 is a plastic suction bottle that serves for sucking out secretions from wound cavities, with the suction bottle displaying a connecting part for attaching the actual suction line, and is combined with a pressure indicator.

In particular, it is useful for sealing and conglutinating of internal and external wounds, for securing sutures, and for healing of large-surfaced wounds or wound cavities.

Furthermore known from EP 0 637 976 B1 is the use of a light-sensitizing substance or compound or photosensitizer (PS) during production of a medication for use during disinfection or sterilization of tissues in the oral cavity or a wound or lesion in the oral cavity by destroying microbes in a periodontal pocket that are associated with an illness, in the region between the tooth and the gum.

As a result, the flexibility and adaptation of the appropriately perforated biomatrix to irregular surface structures and in particular to cavities such as wound cavities can be further improved.

Particularly in connection with the treatment of wounds, however, in addition an extremely high flexibility for a spatial or three-dimensional modelling capability of the stratiform materials is also desirable, in order to obtain, particularly in connection with the treatment of wounds with deep skin defects or with large wound cavities, as complete and homogeneous a packing or covering or tamponade as possible of such deeper skin defects or wound cavities.

Such wound overlays configured in uniform or continuous homogeneously planar manner on the basis of biomatrix materials have, as a rule, only a limited flexibility and can only be fitted into wound cavities or deep wounds homogeneously and in completely packing manner to a limited extent.

Consequently, deep and irregularly formed wound cavities can, for the most part, only be covered inadequately and incompletely with such biomatrix wound-treatment materials designed in uniformly planar manner and, even with the use of a very flexible fleece, as a rule a complete tamponade of the wound cannot be obtained.

Overall, with stratiform wound-treatment materials configured in continuous homogeneously planar manner, such as have been known and customary hitherto, an even and homogeneous application on planar wound cavities and also a complete and homogeneous spatial covering of deep wound cavities are only insufficiently possible, and such materials are furthermore associated with the disadvantage of a further adaptation of shape by application of mechanical cutting tools.

This construction also offers the advantage that in contrast to a flat pad—the shavings can extend three dimensionally when swelling, thus forming a convex surface, similar to a casting, and, for example, can fill up wound cavities.

As a result, in the event of an excessive swelling in the packed wound cavity an undesirable excess of wound-treatment material and, as a result, where appropriate, an increase in the pressure in the wound cavity by reason of the excessive increase in volume may arise, having a negative effect on the treatment, since, as a result, on the one hand the healing of the wound is disturbed and, on the other hand, the patient is subjected to unnecessary wound pain.

The stratiform and optionally perforated or slit overlays known from the state of the art are consequently not provided with a sufficient flexibility for a high spatial modelling capability or modulation capability with a view to optimal covering of wound cavities and deep skin defects with simultaneous good planar applicability and modelling capability or remodulation capability with simultaneous simple and variable planar adaptation of shape and high biological compatibility and degradability, in order to be suitable both as cosmetic skin-care agent and also as therapeutic wound-treatment agent and implant.
