Definitions

  • the present invention relates, generally, to medical adhesive tapes for use in adhering medical appliances, dressings, etc., to the skin. More specifically, the present invention is directed to a medical adhesive tape, having high water vapor permeability and water resistance at the same time, by coating the adhesive on a base sheet to form a net-shaped structure.

  • surgical tapes such as surgical tapes, plasters (first-aid plasters), etc.
  • plasters first-aid plasters
  • the adhesive tape is composed of an adhesive coated on a base sheet.
  • Such an adhesive tape should have adhesion suitable for firmly adhering the medical appliances or dressing materials to the skin and then easily removing them from the skin. Further, the tape should have high water vapor permeability to avoid normal skin damage because it is directly attached to the skin, in which high water vapor permeability can promote wound healing.
  • the adhesive tape has the pressure-sensitive adhesive coated onto an entire surface of the base sheet.
  • conventional tapes are disadvantageous in terms of low water vapor permeability, due to the coated adhesive per se, regardless of the water vapor permeability of the base sheet. That is, even though the base sheet having high water vapor permeability is used, the adhesive coated to the entire surface of the base sheet can fi nction to hinder water vapor permeation, therefore decreasing the water vapor permeability of the tape.
  • FIG. 1 shows a conventional medical adhesive tape.
  • an adhesive 2 is dot-coated on a base sheet 1 to form a non-coating part la, thus obtaining circular coating parts 2a.
  • gas is easily permeated through the non- coating part la to increase water vapor permeability, however, water is infiltrated into a wound or medical appliance.
  • the user of the adhesive tape may come into contact with water.
  • water resistance is required to protect the wound or medical appliance.
  • water may be infiltrated through any sides of the conventional adhesive tape.
  • the conventional tape has no water resistance.
  • dot-coated circular coating parts 2a are discontinuously formed, that is, the coating parts 2a are not mutually connected, whereby water is infiltrated between the coating parts 2a.
  • Such infiltration of water leads to maceration of the skin, which is harmful to the wound.
  • margins of the base sheet 1 are not coated with the adhesive 2, and the tape loosens at the non-coated margins and thus may be easily removed from the attached skin during use.

  • the base sheet 10 is formed of a resin film having liquid impermeability (water resistance) with gas permeability (water vapor permeability).
  • the resin film used for the base sheet 10 to have high water vapor permeability is exemplified by synthetic polymers, such as polyurethane, polyethylene, silicone resin, natural and synthetic rubber, poly gly colic acid, poly lactic acid or copolymers thereof poly vinylalcohol and poly vinylpyrrolidone, and natural polymers or synthetic polymers derived therefrom, such as collagen, gelatin, hyaluronic acid, sodiu- malginate, chitin, chitosan, fibrin and cellulose, or mixtures thereof More preferably, a polyurethane film is used.
