  • Each eye formation 30 has a closure in the form of a screw cap 31.
  • the bag 14 also has an identical eye formation 32 with a screw cap 33.
  • the screw cap 33 of the eye formation 32 may, in other embodiments, be replaced with a connector 34 for an oxygen supply line (not shown), if required.
  • the eye formation 32 will then define a secondary inlet of the bag 14.
  • a slit 36 is defined in the wall of the bag 14.
  • the slit 36 has a slide fastener 38 which, when closed, is substantially air tight. When the slide fastener 38 is open, the slit 36 forms an access aperture for the bag 14.
  • the bag 14 has also three discharge outlets 39.1, 39.2 and 39.3.
  • the outlets are served by valves 40.1 , 40.2 and 40.3 respectively which allow them to opened and closed as required.
  • the purpose of the outlets and valves will become apparent from the following description.
  • the bag member 14 also carries suspension formations in the form of lugs 41.1 and 41.2 by means of which it can be suspended from an overhead support structure (not shown).

  • a suspended plastics bag 52 containing a saline solution, is suspended over the supply line 44 and can feed saline solution into the line under the control of a flow control valve 54. In the line the saline solution may be nebulised or vaporized for incorporation in the gas flow.
  • the bag 52 has a heating lamp 56 for heating the saline solution in the bag.
  • the arrangement 12 includes also a gaseous fluid supply line 60 which branches from the line 44 and terminates at an irrigator nozzle 62.
  • the discharge pipe 16 is connected to the valve 40.1.
  • the container 18 is closed by means of a lid 66.
  • the pipe 16 extends through an opening in the lid 66 with its bottom end 68 disposed near the bottom of the container 18 as shown.
  • the container 18 is partially filled with an antiseptic receptor liquid (not shown in Figure 1) with the end 68 of the pipe 16 submerged in the liquid.
  • the apparatus 10 can include one or more body part supports.
  • a typical one of these supports, designated by the numeral 70, is shown in Figure 3.
  • the support 70 has a dimension, into the plane of the paper in Figure 3, which may be approximately twice that of the vertical height of the support.

  • the body part supports 70 are adhered to the inner surface of the bag member at positions opposite to the lugs 41.1 and 41.2. Normally, the orientation of the body part supports will be such that the recesses 74 extend from left to right in Figures 1 and 2.
  • the forearm 28 is inserted into the open mouth 22 of the bag member 14 and is rested upon the supports 70 with the wounded upper surface of the forearm facing upwardly such that the lugs 41.1 and 41.2 are situated above the forearm.
  • the mouth 22 of the bag is then secured about the forearm by tying the straps 26 in an appropriate manner, with the gauze seal 24 providing a sealing action.
  • the bag member 14 can then be suspended from an overhead support by means of the lugs 41.1 and 41.2, typically with the lug 41.1 slightly higher than the lug 41.2.
  • the line 44 is connected to the inlet 46 of the bag member 14 in the configuration shown, and the pipe 16 is connected to the valve 40.1 with the other valves 40.2 and 40.3 closed.
  • the pipe 16 may be connected to one or other of the valves 40.2 and 40.3, in each case with the other two valves closed.
  • the pumps 42 are actuated to pump air through the line 44.
  • the filter 48 filters impurities from the air.
  • the air passes through the ozone device 50, which introduces ozone into the air to form a gaseous fluid mixture.
  • the lamp 56 is energized to heat the saline solution in the bag member 52 to a desired temperature.
  • the valve 54 is opened to a required extent so that ⁇ saline solution is drawn into the gaseous fluid flow in the line 44 and is entrained in that flow, typically in a nebulised or vaporised state.
  • the fluid mixture comprising air, ozone and saline solution in nebulised or vaporized form is accordingly introduced into the bag member 14 through the inlet 46.
  • the inlet pressure is sufficient to maintain the bag 14 in an inflated state.
  • the internal space 77 defined in the inflated bag is partially occupied by the forearm 28.
  • the gaseous fluid circulates through the unoccupied portion of the space 77 from the inlet 46 to the outlet valve 40.1. In so doing the fluid circulates over the wound on the forearm 28 to aid healing thereof.
  • the slide fastener 38 may be manipulated to open the slit 36 in order to allow access to the wound in order to attend to it as necessary.
  • Any liquid fluids, including any wound exudate, which accumulate in the bag 14 can be drained from the bag through the outlet 39.1.
  • Such fluids, as well as gaseous fluid exhausted through the outlet 39.1 are then discharged through the pipe 16 into the receptor liquid in the container 18.
  • the recesses 74 allow liquid fluids to flow along the bottom of the bag towards the outlet.
  • a selected one of the caps 31 may be removed from its eye formation 30, whereafter the nozzle 62 can be inserted through or attached to the associated irrigation aperture. The nozzle 62 can then be triggered to dispense gaseous fluid supplied to it through the line 60 directly onto the wound.
  • FIG 4 shows another embodiment of the invention.
  • the bag 14 is in the form of a sleeve both ends of which are open.
  • the sleeve-like bag in this embodiment is, as before, fitted over a left forearm 28.

  • the hand 80 With this configuration, which is suitable for use in situations where the wound is situated between the wrist and the elbow, the hand 80 remains free.
  • Figure 5 illustrates another embodiment of the invention, and like components are again indicated by like numerals.

  • the wound 90 is typically a burn wound, ulcer, pressure sore or the like which is prone to bacterial infection.
  • the dressing in this embodiment is one manufactured and sold under the name ActicoatTM or Acticoat 7TM by Smith & Nephew Healthcare Limited. If necessary, the dressing may be secured in place by means of an external bandage or other fastening means (not shown).
  • ActicoatTM and Acticoat 7TM dressings carry fine particles of metallic silver which serve as an antimicrobial agent to combat bacterical infection.
  • the dressing it is recommended that the dressing be kept moist, both in order to maintain a moist, wound-healing environment and to prevent the dressing from drying out and adhering to the wound site.
  • moisture is provided from a container 94 of sterile water. Water from the container 94 is drawn into the line 44 through a line 96 controlled by a valve 98. If necessary the water in the container may be heated by a heating lamp or other heating device 100.
  • the line 44 may if necessary include a venturi formation designed to generate a low pressure in the air stream to draw the water into the line.
  • the various parameters are such that the water is either nebulised or forms water vapour in the air stream.
  • the air stream is accordingly moistened by the introduction of the sterile water.
  • the bag 14 includes an outlet 39.1 leading into the line 16 which is, as before, controlled by an outlet valve 40.1.
  • the moistened air stream circulates through the bag from the inlet 46 to the outlet.
  • the pressure of the moistened air stream circulated through the bag is maintained at a level sufficient to inflate the bag in order to form a moistened volume around the forearm 28.
  • the dressing 92 is able to perform an efficient antimicrobial action. Water which precipitates out of the air stream in the bag, together with any liquid exudates from the wound 90, are able to leave the bag through the outlet 39.1 and the line 16.
