Abstract

Wound therapy device for the treatment of pressure ulcer wounds and wounds on body parts, characterized in that a pressure ring (1) the wound decubitus (23) relieved, with a blue light string (19) is equipped and by a mounted oxygen tube (11) a topical Wundoxigenierung for wound healing is applied.

Description

The invention relates to a wound therapy device for the treatment of wounds by means of blue light, oxygen action at 30-50 mbar pressure and pressure relief of the wound by the manually fillable pressure ring.

Surgical procedures are becoming more complex. The care of high-risk patients is steadily increasing. On this basis, the wound therapy device is to be used in the risk reduction of pressure sores and hard-to-heal wounds. Due to its uncomplicated structure and compact functionality, the wound therapy device enables optimum wound treatment through the use of blue light, oxygen pressure 30-50 mbar and pressure relief, d. H. by factors that prevent the formation of pressure sores and thus heal wounds more optimally and faster.

It is described a drainage for the treatment of pressure ulcers of bedridden, especially in hospitals and care facilities. The requirements of drainage of this kind are to create for the bedridden conditions that prevent bedsores or contribute, for example, even in the case of already existing bedsores or burns on the body to heal. For this purpose, a high moisture absorption and good ventilation must be ensured.

The DE 10 2004 021 972 A1 is characterized by the fact that the patient bed has a plurality of matrix-like, height-adjustable elements which are individually adjusted in height. The patient lies on a mat.

• – eine oben liegende Polstereinheit umfasst zumindest ein Abstandsgewirk mit einer oberen Gewirklage, einer unteren Gewirklage und diese verbindenden Polfäden, wobei die obere Lage aus multifilen Fäden besteht und sämtliche Polfäden durch monofile Fäden gebildet werden,
• – eine untenliegende Saugeinheit besteht aus einer Vliesmatte mit hohem Anteil Viskosefasern, die außen mit einer wasserundurchlässigen Bahn beschichtet ist,
• – die Polstereinheit und die Saugeinheit sind zerstörungsfrei trennbar und wieder verbindbar miteinander verbunden.

The DE 196 15 187 C2 shows a bed mattress for the prevention of pressure ulcer bedridden, especially for hospital beds, which is characterized by the following structure:

• An upholstered pad unit comprises at least one spacer knitted fabric with an upper knitted garment, a lower knitted garment and these connecting pile threads, the upper layer consisting of multifilament threads and all the pile threads being formed by monofilaments,
• - an underlying suction unit consists of a non-woven mat with a high proportion of viscose fibers, which is coated on the outside with a water-impermeable web,
• - The upholstery unit and the suction unit are non-destructively separable and connected again connectable.

In the DE 100 55 902 A1 a mat is described. This consists of an upper layer, which is made of predominantly hydrophobic, synthetic fiber material. Furthermore, the medical aid consists of a lower textile layer, predominantly hydrophilic, cellulosic thread material with material-intensive binding. Between the upper layer, an intermediate layer of pile threads forming the spacer structure is arranged.

The improvements are intended to be achieved by the full and even support of the lying patient, the secure ventilation of the support surfaces, the fast and safe removal of body fluids from the contact surface between the body and the medical device to the body-side surface and at the same time by the protection of the mattress system Pollution by body fluids can be achieved. The invention relates to a three-dimensional composite in the form of a spacer structure, which is suitable for medical auxiliary purposes.

• – die Wunde mit Schaumstoff auszulegen,
• – die Wunde mittels Klebefolie dicht abzukleben

und mit einem Vakuum durch einen, auf der Klebefolie befestigten Port, Sekret abzusaugen. Sämtliche Lösungen haben das Problem, dass der Schaumstoff kein geeignetes Aufnahmeprofil, z. B. bei der Behandlung einer Ferse, aufweist und eine optimale Platzierung des Schaumstoffes sowie eine optimale Wundbehandlung nicht möglich ist. Des Weiteren sind die Ports mit einem Abflussschlauch verbunden, der zu dicht an der Wunde platziert ist und somit stets für Druckstellen am Patientenkörper sorgt und für den Patienten keinen guten Tragekomfort bietet.Furthermore, pressure ulcer pads with pneumatic and hydraulic pressure elements are known which continuously change the pressure load and thereby promote the circulation of the tissue. These pads are very expensive and expensive and therefore more suitable as a whole body pad. The pressure ulcer wounds are treated by means of vacuum therapy. There are the following solutions:

• - cover the wound with foam,
• - Mask the wound tightly with adhesive foil

and to suck away secretions with a vacuum through a port attached to the adhesive film. All solutions have the problem that the foam no suitable receiving profile, z. As in the treatment of a heel, and optimal placement of the foam and optimal wound treatment is not possible. Furthermore, the ports are connected to a drainage tube which is placed too close to the wound and thus always provides pressure points on the patient's body and does not offer the patient good wearing comfort.

On this basis, the main object of the invention is to apply an optimal wound dressing with pressure relief by a pressure ring with oxygen supply by an oxygen source with a system pressure of oxygen of about 50 mbar. This pressure causes an increase in the oxygen partial pressure in the wound tissue many times, whereby an effective and rapid wound healing can take place.

The 1 shows a therapy device for wound healing with a pressure ring ( 1 ) connected to a pressure line ( 2 ), with control balloon ( 3 ) and valve ( 4 ) and manually by compressed air ( 5 ) a desired level of relief ( 16 ) reached. The pressure ring ( 1 ) is by means of wound film ( 8th ) through an adhesive layer ( 7 ) and connection ( 10 ) over the wound ( 23 ) on the body part ( 6 ) attached. In the pressure ring ( 1 ) is an oxygen tube ( 11 ) for the supply of oxygen ( 12 ) and a pressure build-up in the pressure chamber ( 17 ) placed at about 30-50 mbar. The pressure ring ( 1 ) is with a cover sheet ( 9 ) for forming the pressure chamber as a pressure chamber ( 17 ) taped. A pressure valve ( 24 ) in the cover sheet ( 9 ) regulates the required pressure of oxygen ( 12 ). Due to the placement of blue light strands ( 19 ) blue light rays ( 15 ) on the wound ( 23 ). The blue light strand ( 19 ) is connected to a blue light line ( 13 ) and blue light lines ( 14 ) connected. Special seals ( 18 ) on the oxygen tube ( 11 ) and the blue light line ( 13 ) keep the oxygen pressure in the pressure chamber ( 17 ) upright. The oxygen ( 12 ) works with a pressure of 30-50 mbar.

In the 2 is the design of the blue light insert by means of protective film ( 21 ), Blue light film ( 22 ) with the blue light rays ( 15 ) and blue light strands ( 19 ). The blue light strands ( 19 ) are connected to a blue light line ( 13 ) and blue light lines ( 14 ) connected. An opening ( 20 ) in protective film ( 21 ) and blue light film ( 22 ) allows the undisturbed passage of oxygen ( 12 ) to the wound ( 23 ). The blue light causes additional wound activation and wound healing.

The 3 shows the application of an elastic pressure cuff ( 25 ), which in the supply of oxygen ( 12 ) through the oxygen tube ( 11 ) causes pressure equalization with 50 mbar and at which the adhesive layer ( 7 ) not from the wound film ( 8th ) releases. The pressure cuff ( 25 ) around or on the body part ( 6 ) attached.
