Abstract

A drainage device for wound treatment and suction of wound exudate (18) from wounds (17) using a wound film (24) having a secretion hole (21), characterized in that the drainage device is provided by the connection of two perforated flat wires (1) provided with collapsing ribs (3) and perforation (2), with a round pad (16) over the secretion hole (21) of the wound film (24) suction secretion (18) by means of vacuum from a wound (17).

Description

  • The invention relates to a drainage device which can be used for various methods of wound treatment, but in particular for the drainage of wound secretions from wounds.
  • State of the art
  • It is a common task in medicine to suck out wound fluids. In particular, in the case of deep, large and, in particular, infected surface wounds, the hitherto customary practice is to place a wound dressing in the wound which does not weave with the tissue. On this wound dressing the physician brings a first layer of gauze, in which then by hand a drainage tube, partially wound several times, is applied and this covered again with a second layer of gauze and then the entire wound site is covered with a plaster. The end of the drainage tube is then subjected to a negative pressure, whereby the wound fluid can be sucked off.
  • In addition to the long duration of time required to lay the above described means, this approach also requires considerable skill of the medical practitioner, because during wound care, all separately inserted device components are to be fixed, which often can not be accomplished by one person alone.
  • Another type of wound dressings that have been developed in particular for the vacuum wound treatment is, for example, in DE 601 18 546 T2 described.
  • The wound dressing described there requires, on the one hand, a relatively high manufacturing outlay and, on the other hand, is not readily adaptable to different wound sizes. In order to carry out a vacuum treatment, this solution requires, on the other hand, other relatively complicated supplementary supports and, as a rule, bell-shaped seals of the wound, to which an external vacuum connection is attached. Such, the skin surface far superior designs significantly restrict the freedom of movement of the patient and also generate unpleasant additional pressure loads.
  • The above-outlined treatment of such wounds under negative pressure is a method practiced for many years, which positively influences the healing of deep and large-area wounds by permanent wound stimulation. This type of vacuum wound treatment is, for example, in DE 694 25 881 T3 . DE 692 29 940 T2 and DE 692 24 847 T3 described in detail, which is why reference should be made here only.
  • In addition, there are a variety of other solutions, which should be listed here only as an example, because they concern more distant technical solutions. That's how it is US 6,695,824 B2 a wound dressing cover for outer flat wounds consisting of two layers, the first layer being applied directly to the wound and the second layer having an outward-acting moisture barrier. Between the layers mentioned several hose-like supply lines are provided which ensure a moisture supply to the wound.
  • For use in the context of wound treatment of deep, poorly healing wounds with the aid of the technique of vacuum wound treatment, however, the abovementioned wound dressing cover is not designed and also unsuitable, because a vacuum-tight lead-out of the sometimes multiple hoses from the wound area is practically impossible.
  • The same applies to a variety of devices for the extraction of wound secretions from body cavities, such. In EP 1 764 127 A1 described.
  • Furthermore, in the EP 2008/003251 a flat drainage with a derivative tail described.
  • From the DE 698 25 767 T2 and DE 698 33 579 T2 Suction heads for wound treatment and a combination with a surgical drape are known in that a port with adhesive tape and suction tube is glued to a wound over the wound film.
  • The disadvantage here is the hard port, which presses upon application of a vacuum on the wound and causes pain.
  • Other applications also use ports that differ only in other shapes and materials as well as different exhaust ducts.
  • Again, the hard port is a disadvantage to the patient.
  • Furthermore, the use of the hard ports for small wounds with respect to air circulation in the wound area is unsuitable, since the small adhesive surface is not adequately ventilated beyond the wound area.
  • This obstructs the aspiration of the wound secretion. Only by a special pump, the Through the suction hose allows ventilation of the wound, the suction process of wound secretion can be maintained.
  • The DE 20 2010 009 148.9 describes a suction system with a foam labyrinth and a wound ventilation system.
  • In the DE 20 2009 017 621.5 is described a labyrinth drainage based on air cushion.
  • A labyrinth drainage hose system describes the DE 20 2008 004 737.4 ,
  • In the DE 20 2010 012 324.0 For example, a suction device for wound treatment and suction of wound exudate from wounds using a wound sheet with a flat silicone drain and a rectangular sticker is described.
  • All previous descriptions do not use a flexible flat drain with internal collapse protection, which is very flat, very soft and is used with a length of approx. 100 mm.
  • task
  • The present invention has for its object to provide a drainage device that guarantees a secure connection to a cut in the wound cover film hole through labyrinth, so that the secretion unhindered by the drainage device in the suction hose, when applying a vacuum or passive, can pass.
  • Furthermore, the labyrinth material should be of a soft and flexible structure, preferably silicone, so that upon application of a vacuum by hard parts, no additional wound pain arises.
  • According to the invention this object is achieved by the characterizing features of the first claim and supplemented by advantageous embodiment according to the subclaims.
  • The essence of the invention is that the drainage device consists of a flexible silicone drain with internal Kollabierungsrippen, is perforated and can be glued with a round pad over a wound film with an opening.
  • In the contact or adhesive area, a hole is cut into the wound film by means of scissors.
  • This allows unrestricted secretion supply through the flexible drain to the secretion collecting container.
  • The coupling - wound film and drainage device - is achieved after removing a protective film from the round pad by an adhesive layer.
  • In the contact area with the wound film, a large hole is left in the sealing film. This ensures unrestricted secretion supply through the respective flexible, porous, soft labyrinth into the suction tube and to the secretion collecting container.
  • The invention is explained in more detail below with reference to schematic drawings.
  • Show it:
  • 1 A first embodiment of the drainage device according to the invention in a section
  • 2 : A plan view of the first embodiment of the drainage device according to the invention

  • The 1 shows a first embodiment of the drainage device according to the invention using two Flachdrains ( 1 ) with a drain strength ( 23 ), with ribs ( 3 ) as Kollabierungsschutz and perforations ( 2 ) are equipped.
  • The flat dtrains ( 1 ) are coated with an adhesive film ( 5 ) on the round pad ( 16 ) connected. About the Flachdrains ( 1 ) is a capillary-free sealing film ( 4 ) with an adhesive layer ( 6 ) and with the round pad ( 16 ) connected.
  • The perforation ( 2 ) goes through the protective film ( 8th ), the adhesive bond ( 7 ), the round pad ( 16 ) and the adhesive film ( 5 ).
  • The drainage hoses ( 10 ) are connected ( 11 ) connected. The connection ( 11 ) is connected to the suction hose ( 13 ), so that in a vacuum, the secretion in the suction direction ( 12 ) is sucked off.
  • The flat dtrains ( 1 ) are frontally with a seal ( 15 ) and in the perforation circle ( 14 ) to the protective film ( 8th ) with perforations ( 2 ) produced.
  • Is the protective film ( 8th ) by means of handles ( 9 ), the adhesive bond ( 7 ) free, so that the perforation ( 2 ) over the secret hole ( 21 ) on the wound film ( 24 ) can be glued.
  • The 2 shows the round pad ( 16 ) with two Flachdrains ( 1 ) and in the perforation circle ( 14 ) incorporated perforation ( 2 ) as well as the sealing of the Flachdrains ( 1 ) through the seal ( 15 ).
  • The drains ( 1 ) can be offset or used individually, so that the one drain hose ( 10 ) can be used without connector as Zusufitz- or ventilation hose.
  • In the 3 is the application with a wound ( 17 ).
  • The wound ( 17 ) is filled with a wound filling ( 22 ) and with a wound film ( 24 ) on the skin ( 20 ) pasted over.
  • Into the wound film ( 24 ) becomes a secretary hole ( 21 ) cut. About the secret hole ( 21 ) the perforation circle ( 14 ) centric with the round pad ( 16 ) glued.
  • When applying vacuum, the secretion gem. Secretion flow ( 18 ) through the wound filling ( 22 ), the perforation ( 2 ) into the flat drain lumen ( 19 ) and further into the drain hose ( 10 ) to the secretion collecting container.
  • The application of the very flexible, very flat Flachdrains ( 1 ), preferably made of silicone, gives a minimal wound load. Patient flexibility and ease of use are improved and patient burden reduced.
