Definitions

  • the hemostatic coating material containing coagulation factors such as fibrinogen and thrombin on the adhesive surface uses the hemostatic and coagulation mechanism of the living body (biological glue), it has a strong hemostatic effect once adhered. However, it takes about 5 to 15 minutes to complete the hemostasis / coagulation mechanism, so it is difficult to fix the blood during this period. In addition to flexibility issues, it is necessary to pay close attention to the possibility of infection.
  • the microneedles 20 can be formed anywhere on the crosspiece 11 of the support 10.
  • FIG. 1B shows an enlarged side view of the microneedle 20. The distance from the surface 10a of the support 10 to the tip 20t is the height 20h of the microneedle 20.
  • the peak 10p is applied along the length direction of the wound 42. Then, the bending of the wound surface covering material 1 is released. The microneedles 20 straddle the wound 42 and penetrate the outer tissue surface 40. In this way, the scratch 42 is fixed.
  • the wound surface dressing 1 has a structure such that the central portion is likely to be the peak 10p.
  • the microneedle 20 is preferably formed so that both sides of the ridge 10p face inward so that the wound 42 can be easily fixed.
  • the microneedles 20 inclined toward the ridge 10p sandwich the tissue outer surface 40 of the wound 42 toward the wound 42, so that the adhesiveness of the wound surface covering material 1 is enhanced.
  • the wound surface covering material 1 according to the present invention can be suitably used for hemostasis / adhesion of the wound surface in the body.

Abstract

L'invention concerne une feuille qui comprend des facteurs de coagulation tels que le fibrinogène et la thrombine, et qui est utilisée en tant que matériel de recouvrement de plaie, a une adhésivité élevée au tissu du corps, mais présente un problème de flexibilité et nécessite en outre un degré élevé de prudence concernant la possibilité d'une infection. Par ailleurs, un matériel de recouvrement de surface de plaie d'un matériau biolytique n'est pas problématique vis-à-vis d'une infection, mais n'a pas d'adhésivité ou de capacité hémostatique élevée et reste un dispositif hémostatique secondaire. Ce matériel de recouvrement de surface de plaie est caractérisé par le fait que : un corps de support en forme de maille et des micro-aiguilles formées sur une surface du corps de support sont inclus ; le corps de support et les micro-aiguilles sont formés à partir d'un matériau biolytique ; et le module de Young apparent est de 2,0 MPa à 2,0 GPa. Le matériel de recouvrement peut augmenter la sûreté vis-à-vis d'une infection et ne se déplace pas de la zone où le matériel de recouvrement est placé en raison de l'effet adhésif des micro-aiguilles.
