Abstract

Device for the removal of wound secretions from body cavities and wounds, characterized in that drainage materials (4) embedded in a flexible protective sheath pocket (3) with perforations (2), with perforations (11) and flap (1), organs and wounds protect the serving.

Description

The invention relates to a device for removing wound secretions and liquids. The device is particularly suitable for the permanent removal of wound secretions and fluids from body cavities and wounds.

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

The composition of the wound secretions, which are mainly fed from the cell interstices, can vary widely. They contain predominantly admixtures of serum proteins and traces of blood constituents. In an infection, wound secretions also contain increased amounts of macrophages to eliminate the microorganisms. This can be linked to the formation of pus. If the wound exudate from an inflamed body cavity is not removed, this leads to the formation of abscesses.

Various devices are used in practice to remove wound secretions from body cavities.

The use of drainage tubes, abdominal towels or smaller sponges is known.

However, the known devices are associated with disadvantages.

The use of drainage tubes very quickly leads to the formation of channels in the body cavity. The wound secretion in the body cavity is thus extracted only when it is in the vicinity of such a channel. Otherwise, it remains in the body cavity. Drainage hoses are therefore not suitable for permanently and as completely as possible suction of wound secretions. Drainage hoses are mostly made of silicone.

Bellycloths are usually rectangular layers of cotton or a similar soft and absorbent material that are incorporated into the body cavity. The absorbent material absorbs the wound secretions present in the body cavity. Naturally, however, such a belly cloth has only a limited capacity for absorbing body fluids. For this reason, it is necessary to remove the abdomen after a certain time from the body cavity and replace it with a new one. This replacement of the abdominal sheets is associated with surgery and permanent anesthesia, which can adversely affect the patient's physical and mental condition. Moreover, the practitioner who puts a belly-cloth into a body cavity has to make sure that it is replaced before its capacity is actually exhausted. For this reason, the practitioner has to speculate when this will be the case.

Sponges are too crude and inflexible to bring into body cavities. Since the sponges are rigid and too small, they can only be used in small body cavities. Due to the nature of the sponges is to be expected damage to organ surfaces. The non-aspirated sections of the body cavity stick together and can ignite. They are therefore not or only very limited suitable for the suction of wound secretions from body cavities.

Sponges are therefore used primarily for the treatment of external wounds. For this purpose, the sponge is applied to the wound, the wound and the sponge thereon covered with a vacuum film and the sponge connected to a drainage tube, via which 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.

The sponge can be tailored to the size of the wound by cutting. However, the sponge must not only cover the wound but also have a certain thickness over the wound to provide even distribution of negative pressure across the wound surface.

However, a particular disadvantage is the risk that the sponge clogged, so that the negative pressure can no longer be distributed evenly over the wound surface.

Another disadvantage is the too large sponge thickness - in body cavities.

• 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.

This invention also has all the disadvantages such as the risk of blockage or organ injury, as 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 008 788.3 describes the use of two connected sponges or foams with inlaid drains to dissipate wound secretions.

The too large thickness of the foam, about 20 mm, brings with the placement in the body cavity and the transport of the secretion problems.

in the GB 20 2010 012 484.0 is a device with a flat position and very low flat layer thickness in application of an installed Flachdrains described.

In EP 1674 127 A1 are two superimposed layers of a foam body indicated with hoses inserted.

Furthermore, devices are known which use drains, which are embedded in channels of foams and coupled with hard fasteners and thus can lead to injury.

The object of the invention is to envelop all known inventions with foam and sheaths of microperforated films by means of additional cover after cutting per wound size so that no open foam after cutting can lead to injury to organs or wounds.

Furthermore, the protective cover should increase the safety when pulling out the respective drainage device from the wound area by securely fixing the protective cover.

Furthermore, the protective cover after cutting and the fixation around the respective drainage device for the doctor provides a very high level of safety compared to known insert films.

Slip-in films cause a high risk of perforation for organs due to slipping.

This object is solved by features of the claims.

Advantageous embodiments of the invention will become apparent from the features of the remaining claims.

• – zumindest ein flexibles, elastisches, weiches, poröses, Wundsekretdurchlässiges Material, vorzugsweise mikroperforierte Folie,
• – zumindest einen Beutel zur sicheren Platzierung des Drainagematerials.

According to the invention, a protective cover for the protection of organs in the removal of fluids and wound secretions from wounds and body cavities is provided for a drainage device, comprising

• At least one flexible, elastic, soft, porous material permeable to wound secretion, preferably microperforated film,
• - At least one bag for safe placement of the drainage material.

The proposed protective cover is preferably made of a microperforated film. The protective cover is made as a bag or bag in which the respective drainage device or the drainage material is placed after cutting according to wound size.

After placement of the cut drainage material in the protective bag, the protective flap is wrapped over the pocket slot inwards, so there is no danger of perforation due to exposed foam.

By applying the protective bag as a bag the doctor is offered a high level of safety in the placement in the wound area, as a disclosure of z. B. rough, open-cell foam is excluded.

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

The device according to the invention can be used, 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 promotes a permanent and complete removal of wound exudate from body cavities. The blood circulation at the feeding points is improved, edema is reduced, the risk of a compartment syndrome is reduced, and the purge and healing are stimulated. The number of surgical interventions can be significantly reduced. Moreover, one will Healing of a wound in the body cavity is promoted by improved blood circulation.

Due to the flexibility and softness of the material and the wrapping function as well as the individually adjustable thickness and size, it can be introduced into the body cavity without complications.

Due to the ongoing occlusion of the body cavity using the device of the present invention, the risk of external germination by daily operations can be reduced.

It may be the entire body cavity, for example, the entire abdominal cavity, which has a huge surface compared to other body cavities, be sucked using the device according to the invention.

The device may remain in the body cavity for several days. Thus, the patient can get along without anesthesia in the meantime.

The device is placed under anesthesia in a body cavity of a patient. A mobilization of the patient after this operation is readily possible; as well as an oral diet by the patient. The number of operations and thus the number of surgical scars are reduced to a minimum.

The device according to the invention allows the continuous removal of toxins, bacteria, metabolic products, wound fluid, viruses, etc. from body cavities. All organizational spaces can be treated with the device.

The device is not limited to the removal of wound secretions. Likewise, other body fluids can be removed from wound cavities and open surface wounds.

The focus of the invention is that by cutting the drainage device described, for. B. open-cell foam, an individual adaptation to the respective wound is possible without the risk that open foam wounds and injured organs, as the inventive protective cover prevents this and when placing in the wound and when pulling out the complete drainage device with protective cover a high Application security exists.
