Definitions

  • the invention relates to a vacuum assisted drainage system.
  • Direct wound drainage has been known for many decades. Devices for wound drainage using sponges introduced into the wound are based on this prior art and were developed more than 60 years ago.
  • the document DE 847 475 discloses a device for the drainage of wounds by means of soft tampons, one with its one end in a tampon from expediently fine-pored and soft elastic natural, rubber, foam rubber, cellulose sponge, gauze, cotton wool or the like incorporated, within the tampon open suction line (or more such lines) is (are) provided.
  • the suction line can be divided over a fork in several branches that drove into the tampon.
  • tubes (flushing lines) for supplying rinsing, disinfecting or healing fluid to the wound may be present.
  • a portable wound treatment device which consists of a porous, liquid-permeable pad for insertion into the wound, a dressing to cover the wound and to provide a substantially air-tight seal around the wound around, a the Pad is constructed with a suction pump connecting the Dramage ein and at least one filter, so that can be sucked on the wound to withdraw liquids from there, wherein a pressure-detecting device is provided which monitors the pressure substantially at the sore spot.
  • the disadvantage of all known sponge-mediated wound drainage devices is that the fluid-permeable pad (the sponge) in the wounded state is added by solids that may be present in the fluids and thus clogged, resulting in total failure regarding its drainage effect.
  • the vacuum-assisted drainage system consists of a porous, fluid-permeable cushion for insertion into a wound, a dressing covering the pad and wound and providing a substantially airtight seal around the wound and a drainage line connecting the pad to a suction pump so that it can be sucked on the wound to withdraw liquids therefrom, the pad being provided with a continuous recess in which a rigid, tubular, insertable into the recess Spacer is placed and a second drainage line can be passed through the opening of the spacer.
  • the invention is therefore based on the object of specifying a vacuum-assisted drainage system which prevents clogging of the fluid-permeable pad (of the sponge) during fistula separation in smaller wounds, a drainage effect guaranteed, even if the liquids to be discharged have a solids content and there is insufficient access to the pad for the suction process is given.
  • the vacuum-assisted drainage system consists of a first porous, fluid-permeable pad having a through-hole in which a fistula adapter is placed, the pad and fistula adapter for insertion into a wound from a perforated one Foil are supported, which is in air-tight connection with a cover to cover the pad and the wound and to provide a substantially airtight seal around the wound, wherein in the cover a recess is provided which surrounds the fistula adapter substantially airtight, and a second porous, fluid-permeable pad positioned in part over the first pad on the cover sheet and provided with a sealing film for covering the pad and for providing a substantially hermetic connection to the cover sheet and around the wound.
  • an open drainage line which is connectable to a suction pump so that it can be sucked on the wound to withdraw liquids therefrom.
  • a drainage port may be positioned with air guideways passing through the sealing foil, the drainage port merging into an open drainage conduit connectable to a suction pump so that suction can be drawn to the wound to draw fluids therefrom .
  • the first cushion and the spatially staggered second pad (which is a kind of bridge leading to the drainage line) form a fluid path leading to the wound area outside the wound area during fistula separation in smaller wounds, so that the otherwise insufficient access to the first pad for the suction process is overcome.
  • a drainage bag can be coupled via the fistula adapter or a further drainage line can be inserted into the wound in order to remove more solid components from the wound.
  • this drainage system can be provided with a blood detector, for example a spectroscope with optical fiber, which opens into the drainage line with its detection end.
  • a blood detector for example a spectroscope with optical fiber
  • FIG. 1 shows a first embodiment of the vacuum assisted drainage system according to the invention in a schematic sectional view of the side view
  • Fig. 2 shows a second embodiment of the vacuum assisted drainage system according to the invention in a schematic sectional view of the side view and
  • Fig. 3 shows the embodiment according to. Fig. 2 in a schematic plan view.
  • the vacuum-assisted drainage system shown in Fig. 1 consists of a first porous, permeable to liquids pad (2) and a second porous, permeable to liquids pad (5).
  • the pad (2) is provided with a through recess in which a fistula adapter (4) is placed, the pad (2) and the fistula adapter (4) for insertion into a wound carried by a perforated foil (1) are.
  • the film (1) is in airtight connection with a cover film (3) for covering the pad (2) and the wound and for providing a substantially airtight seal around the wound, wherein a recess is provided in the cover film (3), which surrounds the fistula adapter (4) substantially airtight.
  • the second pad (5) is positioned in part over the first pad (2) on the cover film (3) and with a sealing film (6) to cover the pad (5) and to provide a substantially airtight connection to the cover film (5). 3) and around the wound.
  • Essential to the invention is that between the first cushion (2) and the second cushion (5) shipsleitwege that pass through the cover (3) pass through.
  • an open drainage line (8) which is connectable to a suction pump, so that can be sucked to the wound to withdraw liquids from there.
  • the open drainage line (8) disposed within the pad (5) may be replaced by a drainage port (7) with air guiding paths located above the pad (5), the air guiding paths being penetrated by the sealing film (6 ) and the drainage port (7) passes into an open drainage line (8), which is connectable to a suction pump, so that it can be sucked on the wound in order to remove liquids from there.
  • a second drainage line can also be passed through the opening of the fistula adapter (4).
  • this fistula adapter (4) made of plastic and has an inner diameter in a range of 1 to 5 cm, which adapts to the use in this range is freely selectable.
  • the pads (2) and (5) are particularly advantageous from a solidified plastic foam with a pore size of 0.3 to 2.5 mm.
  • This foam may be, for example, a polyurethane foam having a pore size of 0.35 to 2.3 mm or a polyvinyl alcohol foam having a pore size of 0.4 to 2 mm.
  • the cover film (3) and the sealing film (6) are particularly advantageously provided with an adhesive layer (not shown in the figures), so that a good air-tight seal is ensured.
  • the suction pump (not shown in the figures) advantageously produces a vacuum of 50 mm Hg to 375 mm Hg with airtight sealing of the device according to the invention around the wound.
  • this drainage system can be equipped with a blood detector, for example a spectroscope with optical fiber its detection end in the drainage line (8) opens (not shown in the figures), be provided.
  • a blood detector for example a spectroscope with optical fiber its detection end in the drainage line (8) opens (not shown in the figures), be provided.
  • the vacuum-assisted drainage system according to the invention is used, for example, in fistula separation.
  • the fistula adapter (4) is positioned over the fistula (this area being separated from the aspiratable area substantially airtight) and the liquid wound secretion around the fistula adapter (4) over the pad (2) and (5) [which the cover film (3) and the sealing film (6) are substantially airtight connected to the environment of the wound] sucked through the drainage line (8), whereby through the fistula adapter (4) brought directly to the fistula firmer fistula secretion can be removed directly, for example in a drainage bag (not shown in the figures).
  • the vacuum-assisted drainage system according to the invention be renewed every 3 to 5 days as part of the dressing change.
  • the use of the vacuum-assisted drainage system according to the invention leads to a clogging of the fluid-permeable pad (sponge) during the fistula separation and to ensure a drainage effect even if the fluids to be removed have a solids content while there is insufficient access to the pad for the suction process.
  • the vacuum-assisted drainage system according to the invention is characterized by high care and patient comfort.
