Definitions

  • the present invention refers to a device for rinsing and treating wounds and infected skin portions and comprising a cup-shaped member covering the area to be treated and having its opening towards this, said device further comprising a vessel for a treatment solution, said vessel by way of a tube connection communicates with the interior of the cup-shaped member, at which the treatment solution is intended to fill up at least a substantial part of the volume of the cup-shaped member and forming a liquid surface against the area to be treated for exchanging components between this and the treatment solution, and wherein the interior of the cup-shaped member is arranged to be kept at a lower pressure than the atmospheric pressure.
  • the conventional method for treating chronical and infected wounds, such as bedsores, leg ulcers etc. is manual washing and moist compresses soaked with a common salt solution and if necessary enzymes for promoting the healing process.
  • Debrisan consisting of small, dry, porous beads has been used to a limited extent and is declared to have a better absorption capacity as compared to most common salt compresses.
  • Divices for risning and treating wounds have also been proposed, in which a cup with its opening facing the wound is applied about the wound area, said cup having an inlet and an outlet opening and a liquid is caused to pass through the cup.
  • Said liquid can contain antibiotics and substances which improves the healing process. Bacteria and waste products from the wound are washed away with the cleansing slution.
  • Such a device is shown in DE-OS 2.809.828 and US patent No. 2.280.915. Since often long treatment periods are required for obtaining a desired result large volumes of cleansing solution are consumed, which means great expenses especially if the solution contains substances as antibiotics, enzyme preparations, vitamines etc.
  • the object of the present invention is to provide a device of the kind mentioned in the introduction, which makes it possible to treat wounds and infected skin portions in an economically justified way even during long periods of time and which improves the healing of the wound and besides in certain cases can compensate for an insufficient bloodcirculation, e.g. in leg ulcers.
  • the device according to Fig 1 comprises a suction cup 10 of rubber, plastic or glass and which has an inlet and an outlet opening, to which a feed and a discharge tube 11 and 12 resp. are connected.
  • the discharge tube 12 leads by way of a pump 13 and a sterilizing filter 14 down into a bottle 15 containing a treatment solution.
  • the pump 13 is preferably a so called peristaltic pump.
  • the tube 11 connected to the inlet opening of the suction cup 10 leads from the bottle 15.
  • the interior of the bottle 15 is kept at atmospheric pressure by means of an air tube 15. Oxygen may also be bubbled into the solution by way of a tube 17 to ensure oxygenation of the wound to be treated.
  • the suction cup is applied over the wound area or the infected skin portions to be treated.
  • the solution is caused to circulate through the system and is prevented from leaking out from the suction cup 10 by applying a pressure to the cup.
  • This pressure may be created by an external bandage or by having a somewhat lower pressure inside the cup than in the surrounding atmosphere.
  • This lower pressure may be regulated by the level difference between the bottle and the suction cup. i.e. the hydrostatic pressure difference. It can also be regulated by the flow resistance between the bottle and the suction cup and by the speed of flow.
  • the pressure can also be regulated by a separate pressure regulator.
  • the low pressure in the suction cup provides besides preventing leaking from the suction cup, that interstitial fluid is sucked out from the wound and facilitates that blood components are transported to the wound and that microorganisms are easier washed away from the wound.
  • the suction cup may be of different sizes, shapes and materials, such as glass, rubber or plastic etc.
  • the suction cup has an opening towards the skin area to be treated and inlet and outlet openings for the solution.
  • the size of the opening towards the skin may vary from some mm 2 to some dm 2
  • the volume of the solution may vary from some ml to several liters.
  • the sterlizing filter 14 which may either be placed between the pump 13 and the bottle 15 or between the suction cup 10 and the pump can have a porosity of about 0.22 micron, to filter out all bacteria, up to about 0.80 micron to get a good degree of cleaning of the solution.
  • the sterilizing filter 14 is however in most cases unnecessary and can thus be eliminated.
  • the bottle 15 with the treatment solution may be placed in a thermostatically regulated water bath to ensure a certain temperature of the treatment solution.
  • the active ingredients in the solution to be circulated may be a cleaning agent, compounds for nutrition of the tissue including oxygen, vitamins, amino acids and glucose, drugs of different types such as antibiotics, antiinflammatory agents, e.g. cortison, and enzymes for digestion of necrotic tissue, coagulum and pus.
  • the solution may be of the types used for intravenous infusion or for skin cleaning. It is however possible that a better result may be obtained with new developed solutions for this special pupose.
  • the circulation of the solution enables a larger volume of the solution and by that a greater amount of nutritives, drugs etc. to come in contact with the wound to be treated and to get a continuous sterilization of the solution if the sterilizing filter 14 is used.
  • the circulation will also give an effective cleaning of the wound as the solution all the time will be flowing over the wound and wash away waste products therefrom.
  • a continuous oxygenation of the wound may easily be obtained by bubbling oxygen into the treatment solution in the bottle.
  • the device according to this invention may be regarded as a substitute for the insufficient blood circulation in the ulcer area.
  • the filter 14 and the treatment solution may be exchanged e.g. by arranging a T-connection with a valve between the bottle 15 and the suction cup 10 and between the pump 13 and the filter 14.
  • the pump is eliminated and th cup 10 is connected to the bottle 15 only by way of the tube 11.
  • the outlet opening 10 of the cup is closable.
  • the solution is caused to raise into the cup 10 through the tube 11 by raising the bottle 15 to a higher level, at which the outlet opening of the cup is open.
  • a stopper 18 or the like after which the bottle is lowered to a level below the cup 10.
  • the interior of the cup will then have a negative pressure corresponding to the level difference to the bottle.
  • a certain natural circulation caused by convection will take place within the cup, at which there will be an exchange of components between the wound and the treatment solution.
  • the patients have been treated for approximately two hours daily till the lesions have healed. If pain was felt due to the low pressure the treatment was stopped when the patient so wanted. In one of the patients the treatment was stopped after 45 minutes the first week of treatment. Subsequently the patient could stand treatment for two hours daily.
  • Two patients with leg ulcers due to an established arterial insufficiency, two patients with ulcers due to venous insufficiency, one patient with a diabetic ulcer and one patient with pyoderma gangrenosum have taken part in the preliminary clinical trial.
  • One of the patients with arterial insufficiency had two ulcers that were treated, not simultaneously but in succession.

Abstract

Un dispositif pour rincer et traiter des blessures et des parties de peau infectées comprend une ventouse (10) qui est placée sur la zone à traiter et un récipient (15) pour une solution de traitement, ledit récipient communiquant grâce à une connexion par tubes (11, 12) avec l'intérieur de la ventouse. La solution de traitement est destinée à remplir au moins une partie substantielle du volume de la ventouse (10). Le récipient (15) et la ventouse forment grâce à la connexion par tubes un système liquide fermé pour la solution de traitement. Il est possible d'installer une pompe (13) pour forcer la solution à circuler entre la ventouse (10) et le récipient (15). On crée un effet de succion à l'intérieur de la ventouse (10) en la maintenant à un niveau supérieur au récipient (15).
