Abstract

Wound insert for removing wound secretions from body cavities and wounds, characterized in that an open-pore foam (1) with a soft, elastic, thin, vascular and organs protective, provided with slots (6) foil (2) and foam (1) has a column (11) for the discharge of secretion (10).

Description

The The invention relates to wound inserts for the removal of wound secretions.

The Wound insertion 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. They contain predominantly Additions of serum proteins and traces of blood components. In addition, wound infections contain increased levels of infection Amounts of macrophages intended to eliminate the microorganisms. This can be linked to the formation of pus. Will that be Wound secretion from an inflamed body cavity not removed, this leads to the formation of abscesses.

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

Known is the use of drainage tubes, gauze, Sponges, gauze, swabs, cotton wool etc.

The However, known wound inserts 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 or other plastics.

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 rough and rough to bring them into body cavities to be able to. Because the sponges are rigid and too small are, 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 spread and through. sharp-edged foam structures Injuries occur.

• a) zumindest zwei aufeinander liegende Lagen eines Schaumstoffkörpers aus offenporigem Polyurethan, wobei das Polyurethan eine Porengröße von 10 bis 75 ppi und eine Rohdichte von 14 bis 75 kg/m³ aufweist, und
• b) zumindest einen Schlauch mit offenen Enden, dessen eines offene Ende zwischen zwei benachbarten Lagen des Schaumstoffkörpers eingebracht ist, wobei sich das zweite offene Ende des Schlauches außerhalb der Lagen befindet,

umfasst.The invention EP 1674 127 A1 relates to a device for removing secretions from body cavities. According to the invention, it is provided that the device

• a) at least two superimposed layers of a foam body of open-cell polyurethane, wherein the polyurethane has a pore size of 10 to 75 ppi and a bulk density of 14 to 75 kg / m ³ , and
• b) at least one tube having open ends, one open end of which is inserted between two adjacent layers of the foam body, the second open end of the tube being outside the layers,

includes.

Also this invention has all the disadvantages of organ injury on how they occur when using sponges.

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.

in the GB 20 2009 008 788.3 Two elastic, porous, secretory materials direct the wound secretion through a drain to the outside.

The GB 20 2009 016 012.2 . GB 20 2009 008 788.3 and GB 20 2009 011 664.6 describe the use of a micro- and coarsely perforated PE film to cover the sharp foam structures.

In the patents EP 77 504 . EP 620 720 . EP 86 5304 . EP 108 8569 . EP 85 3950 . EP 101 8967 . EP 121 9311 . EP 144 0667 the foam is incorporated into a gut protection layer. The visceral protective layer protects the intestine from direct contact with the perforated foam.

task The invention is perforated foams through a jacket so protect that no direct contact with the intestine or other organs and wound walls can occur.

All exposed or superficial vessels and organs in or around the wound must be complete be covered and protected.

Of the Foam must not be in direct contact with vessels or organs come.

A thick layer of natural fabric provides the most effective Protection. If not a thick layer of natural tissue present or not possible from a surgical point of view, provide layers of a fine mesh, non-adhesive material or artificial tissue an alternative.

at The use of non-stick materials is at an appropriate level Pay attention to fixation so that it does not during therapy slip.

The Invention solves this problem by the fact that the porous foam with a polyurethane film, by means of Acrylic adhesive layer coated, coated.

The Sheathing and the foam are slit, so that the Surface not with organs and vessels comes into contact with the secretion through the slits in the Foil and can be derived in the foam.

These The object is solved by the features of the claims.

expedient Embodiments of the invention will become apparent from the features of further claims.

The Wound insertion is not limited to the removal of wound secretions. Likewise, other body fluids can removed from wound cavities or body cavities become.

In order to The wound insert can also be used to remove fluids from open wounds and surface wounds.

The Invention will be described below by means of embodiments explained in more detail with reference to the accompanying drawings.

It demonstrate:

1 : a wound insert as a foam with coated foil

2 : a film strip for foam coating.

In the 1 becomes an open-pore foam ( 1 ) shown with a very thin foil ( 2 ) made of polyurethane, thickness approx. 0.08 mm, by means of adhesive film ( 3 ) is coated sheathed.

The foil ( 2 ) is with slots ( 6 ) perforated so that a column ( 11 ) with a gap length ( 5 ) in the foam ( 1 ) arises.

By incorporating the slot ( 6 ) in the film ( 2 ) as well as the simultaneous incorporation of the slot ( 6 ) in the foam ( 1 ), with a gap length ( 5 ), a gap width is (with lateral pressure load ( 4 ), which facilitates the unhindered entry of secretion ( 10 ) into the labyrinthine, open-pored foam for transmission into an exhaust system.

By using slit technology in foil ( 2 ) and foam ( 1 ), the derivative of the secretion ( 10 ) without a vessel or organ coming in contact with the foam.

The applied thin foil ( 2 ) protects vessels and organs from damage.

Should the medical user use the Foam ( 1 ) with pasted foil ( 2 ) for a wound, is gem. 2 an additional foil strip with a slot fitting ( 7 ) which is glued over the interface such that the rough foam ( 1 ) is covered.

The foil strip is covered with an adhesive film ( 3 ), a handle ( 8th ) to peel off the protective film ( 9 ) equipped.
