Technology Highlights

• The invention dressing has an inlet opening for a treatment liquid on the main compress, and in the membrane, on the surface opposite the compress, has a permeability allowing exchange of gases to avoid maceration of the wound and to renew the liquid.
• The invention's inlet or outlet port comprise a compress arm extending from a side of the main compress to traverse the adhesive contour. This type of inlet or outlet can be simply and economically realized.
• The invention dressing has a means of closing the inlet port, comprising a flexible part which comes to lie on this opening. Thus, the inlet is protected from soiling.
• The autonomous invention dressing has an integrated reservoir designed for receiving the liquid. Thus, there is no need to utilize an additional means for effecting the filling of the liquid.
• The invention, with integrated reservoir, has a valve for opening the reservoir towards the main compress, controlled by a knob, permitting a simple and easy control of the reservoir to effect the infiltration of the compress.
• The invention's integrated reservoir allows a slow compress impregnation flow by capillarity, the gas exchange permeability of this compress is sufficient to remove air contained within.
• The invention has a transparent or translucid membrane to follow the advancement of the liquid through the compress and complete filling can be verified.
• The invention's inlet and outlet orifices permit an outflow of liquid to obviate a rise of pressure inside upon an incidental compression of the dressing, e.g. when the dressing sits on a joint of a limb which is bent.
• The invention allows a replenishment with the same liquid, or a different liquid in the course of the progress of the treatment, to compensate for any evaporation or slight liquid seepage.
• The invention's reduced cross section of the inlet and outlet orifices limits the possibility of entry of bacteria into the dressing or their migration towards the compress.
• The invention dressing preserves a great deal longer due to the possibility of recharging with liquid.
• The invention implements, with same dressing, cutaneous or transcutaneous treatments that involve an evolution of the medicinal products utilized. This type of treatment is of particular interest for taking care of lesions such as aphthae, pustules, ulcers, allergies, or for reducing scars.
• The invention reduces the risk of tissue being torn loose during removal of the dressing or replenishing the liquid thus allowing longer preservation of the dressing.
• The invention has a continuity of adhesion of the membrane throughout its circumference, resulting in an absence of risk of propagation of any detachment starting from an inlet or outlet passage that would extend up to this edge.
• The invention comprises of a guiding ring constituting a means of centering the narrowing tip of the bottle, allowing this tip to be positioned and maintained on a rigid part, so as to effect a transfer of the liquid with avoidance of any shifting of the bottle which would cause a loss of this liquid.
• The invention's guiding ring facilitates locating the position of the bore for a visually impaired person as this piece is perceptible by a touch through the membrane.
• The invention allows the simplified treatment of the patient with a single operation of applying the dressing to the skin, which can be done rapidly by lower-qualified staff, which reduces costs.
• The invention membrane is made of plastic, in particular a polyurethane, which is flexible and economical.
