Definitions

  • Dressings are the protection of the injury against the action of external physical, mechanical or biological agents. It is a means that consists of cleaning and applying a sterile dressing to a wound, when necessary, with the purpose of promoting rapid healing and preventing contamination and infection.
  • the dressing's purposes are, therefore, to promote healing, eliminating factors that may delay it, treat and prevent infections, prevent exogenous contamination, protect the wound against mechanical trauma, maintain wound moisture, provide thermal insulation and among many others. Varying according to the nature, location and size of the wound, dressings, in some cases, require immobilization with bandages, in others, exhaustive washing with physiological solution and there are those that require compression, as based on medical studies, compression of scars brings significant aesthetic and functional improvements.
  • the present invention refers to a multi-layer wound dressing to apply negative pressure to a wound.
  • the dressing comprises a bioabsorbable layer, to be placed in contact with the wound; an occlusive outer layer impermeable to fluids; a porous fluid carrier layer positioned between the outer layer and the bioabsorbable layer; and a fluid conduit in fluid communication with the carrier layer, to couple to a negative pressure source.
  • the carrier layer comprises a plurality of fluid passages between the conduit and the bioabsorbable layer to allow transfer of fluid through the dressing and bioabsorbable layers.
  • the bioabsorbable layer comprises a plurality of openings to allow exudate to flow from the wound to the carrier layer.
  • the document no. BR 11 2020 009713 6 which deals with "PROPHYLACTIC DRESSING"
  • the present invention generally refers to a medical dressing for preventing pressure ulcers.
  • the dressing comprises a gel coating having a low pressure resistance; that is, from 5 kPa to 60 kPa at 50% stress, as measured by the compression test described in the specification.
  • the dressing reduces shear and compression forces on the skin and underlying layers of soft tissue and prevents or mitigates the development of pressure ulcers.
  • the objective of the present invention is to present a more accessible dressing option to assist in the treatment of keloids and various scars.
  • the dressing puts pressure on the scar more effectively, unlike the dressings found on the market today, and because it is made with elastic material, it is malleable and may or may not be waterproof, depending on the need.
  • the present invention not only takes into account the mechanical and functional qualities, but also the shape, arrangement and strategic location of its parts and components that, correctly positioned, brought an increase in efficiency without causing any burden to users.
  • Fig. 1 shows an image of the dressing composed of the bandage and the pressure element
  • Fig. 2 reveals a perspective of the compression dressing
  • Fig. 3 illustrates the application of the dressing to one arm, in the biceps region; and Fig. 4 shows the variation of the round-shaped dressing.
  • the present invention patent refers to the "CONSTRUCTIVE ARRANGEMENT APPLIED IN COMPRESSIVE DRESSING", more precisely an elastic dressing (1) with compression element (3).
  • the dressing (1) is basically composed of two parts, the bandage (2) and the pressure element (3).
  • the bandage (2) is made of an elastic and waterproof material or not, being malleable to adjust to the curves and movements of the body, the contact side (4) with the skin has an adherent glue, made of hypoallergenic material.
  • the pressure element (3) has a more rigid structure, but still flexible, this element (3) is positioned in the center of the bandage (2) leaving the entire edge free for better application to the skin, which makes the pressure be effective.
  • Said dressing (1) has the function of pressing and compressing the scar with the aim of producing a decrease in tissue oxygenation and consequently triggering the scar regression process.
  • the dressings (1) can be made in rectangular or round shapes, always with the pressure element (3) following the same shape as the bandage (2), in a reduced size, so that the four sides are free.
