Abstract

Drainage means for draining wound secretion (16) from wounds (15), characterized in that a drainage cord (8) can be divided as a roll (9) by wrapping drainage fillings by means of micro-perforated film (1) through incision (10), as a filling in the wound (15) drains secretion (16) in a vacuum (13).

Description

The invention relates to a drainage means for performing vacuum wound treatments, which allows a problem-free supply of large open wounds.

The healing of large open wounds represents a long-standing problem in medicine. Such wounds, especially if they are infected, make a spontaneous healing usually impossible.

It has been known for many years that applying a vacuum positively influences the healing of deeper and larger wounds. For this purpose, the wound is first provided with a wound dressing, the space of the deep wound, for example, after DE 692 29 940 T2 . DE 692 24 847 T3 filled with an adaptable in the shape of the wound open-cell polymer foam pad and this covered with a sealing film, supported by a rigid cap, passed through a drainage tube (sometimes with the help of complicated devices), then externally a vacuum pump for Suction of wound fluid is connected. This external stimulus exerted on the wound stimulates blood circulation in the wound, continuously dissipates infected wound fluid and ultimately positively influences wound healing.

Furthermore, for the same use in US 6,9 79,324 B2 described a wound drainage system in which a bag is filled with beads, which are preferably made of an antibacterial material (for example silver). In this solution, at the same time a drainage line is embedded in the bag, which is led out laterally from the bag and firmly connected to the bag boundaries. The bag and the drainage drainage must be covered with gel according to the local regulations before a sealing coating, which is glued outside the wound areas, is applied.

In the above-described procedure according to the prior art, not only the manual adjustment of the compact foam pad used is an increased challenge to the surgeon, but such a structure is additionally felt by the patient as painful by the generated and unavoidable pressure effect it is excluded in principle, this porous pad fit to make corresponding to the wound, especially since such wounds should be supplied in the shortest possible time.

The solution after US 6,979,324 B2 In principle, the same disadvantage adheres to what concerns the accurately fitting introduction of the drainage system described therein into the wound.

It would have a very large number of different sizes, each with a drainage tube connected bags are kept, since the wounds to be provided by nature are each different in size and depth. A flush filling the wound with the bag proposed there is thus possible in the rarest cases. If the bag protrudes beyond the surface of the skin, the mechanical pressure loads become unbearable for the patient. Too little filling, however, hampers the desired wound closure.

In the DE 694 25 881 T3 Such wound treatment under reduced pressure is described in more detail.

The foam body, gauze, etc. used according to this known state of the art are intended to ensure that an adhesive film covering it to the outside is not drawn into the wound when a vacuum is applied, which is an indispensable requirement for this method of wound treatment.

The DE 10 2008 020 552 A1 relates to a drainage agent for performing vacuum wound treatments. The task of specifying a drainage agent for the treatment of large and deep surface wounds, which can be accurately brought into the wound by the surgeon without great effort and is not perceived by the patient as disturbing or painful, is achieved in that the inserted into the wound drainage means from a or more prefabricated, well-closed bags, the outer envelope is provided with a plurality of inlet openings and a bag is filled at least a third, however, up to a maximum of two thirds of its maximum receiving volume with a particulate filler.

The present invention has for its object to provide a drainage agent for performing vacuum wound treatments for the treatment of large and deep surface wounds that can be quickly and accurately introduced into the wound by the surgeon without great effort and is not perceived by the patient as annoying or painful.

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 while simultaneously using otherwise conventional and known means for carrying out a Vacuum wound treatment, such as airtight wound covers, drainage tubes for wound secretion removal and Vakuumabsaugvorrichtungen, in the present invention, a specially trained drainage agent is inserted into the wound, the drainage means preferably consists of several prefabricated, well-sealed bags, the outer envelope with a plurality of inlet openings (perforations) is provided and the bag is filled with at least a third, however, up to a maximum of two-thirds of its maximum receiving volume with a drainage agent.

The provision of the drainage means according to the invention makes it possible to supply wounds of any size quickly and without great operational skill with the drainage means, whereby an all-sided concern of the drainage means in the wound area and an optimal skin closure is easily ensured by the special design of the proposed drainage means.

The prefabricated drainage agent used can be produced inexpensively, since it is designed exclusively for achieving a drainage effect and wound filling. Additional suction within the drainage means omitted, since the suction is done by laid between the drainage means or laid on the drainage means usual separate drainage lines. The latter drainage lines are, as a result of the use of drainage means according to the invention, freely displaceable according to the requirements of optimum suction, which likewise represents a considerable advantage over the prior art drainage lines fixed in position.

The invention will be explained below with reference to exemplary embodiments.

In the 1 is a deep wound ( 15 ) shown in a side section.

In this wound ( 15 ) In the example, several drainage means are inserted as a strand. The same are from an adhesive film ( 12 ), which extend beyond the adjacent uninjured skin ( 14 ) and the wound ( 15 ) seals to the outside.

On one the adhesive foil ( 12 ) penetrating or laterally discharging and with this tightly connected drainage line ( 11 ), a vacuum ( 13 ) (not shown in detail), so that through this line ( 11 ) Wound fluid ( 16 ) can be sucked off.

The drainage line ( 8th ) is replaced by a roll ( 9 ) unrolled depending on the wound indication and by means of cutting ( 10 ) tailored in a wonderful way.

In the 2 is the drainage line ( 8th ).

The drainage line ( 8th ) is as role ( 9 ) produced. It preferably consists of a casing which has a microperforated film ( 1 ). This film preferably encloses a flow mat ( 2 ).

As a further filler gauze, gauze, etc. is also suitable. The coated materials must have the secretion ( 16 ).

The medical application of the drainage cord ( 8th ), like in the 3 shown when using a flow mat ( 2 ) the formation of a protection length ( 18 ) by a sufficient connection width ( 17 ).

When cutting by cutting or cutting ( 10 ) through the compound ( 3 ) the protection length ( 18 ).

Depending on the wound indication, the filling amount in the wound ( 15 ) by cutting ( 10 ) adjustable. The envelope of the individual drainage means, such. B. Mull, gauze, flow mat etc. by means of microperforated film ( 1 ) provides optimal wound and organ protection.
