Abstract
상기와 같이 이루어지는 본 발명의 상처치료용 다층 드레싱재는, 상처부위의 습윤유지, 지혈, 삼출물 흡수, 조직재생, 성장인자(growthfactor)공급 등의 복합 기능을 담당하는 밀착층과, 삼출물 관리, 항염 항균 작용, 2차감염방지 기능을 담당하는 CMCS(카르복시메틸 키토산)층이 적층구조를 이루며 각자의 역할을 통해 상처를 능동적이고 효율적으로 치유한다.

Claims (8)
- 상처부위에 접한 상태로 겔(gel)화 되는 성질의 천연 다당류계 또는 키틴계 고분자물질과, 분말의 형태를 취하며 상기 고분자물질의 내부에 분산되고 고분자물질의 겔화에 따라 상처부위로 이동하여 상처의 재생을 촉진하는 양막(羊膜)분말을 포함하고, 상처부위를 커버할 수 있는 넓이와 두께를 갖는 밀착층과;
상기 밀착층의 상부에 적층된 상태로 밀착층을 지지하는 생체적합성 지지체층을 포함하는 것을 특징으로 하는 상처치료용 다층 드레싱재. - 제1항에 있어서,
상기 천연 다당류계 고분자는, 상처부위의 습윤환경을 유지하는 알지네이트를 포함하는 것을 특징으로 하는 상처치료용 다층 드레싱재. - 제1항에 있어서,
상기 생체적합성 지지체층은,
상기 고분자물질의 겔화시, 상처로부터 발생하는 삼출물(渗出物) 관리를 동시에 수행하는 카르복시메틸 키토산으로 이루어진 CMCS층인 것을 특징으로 하는 상처치료용 다층 드레싱재. - 제3항에 있어서,
상기 생체적합성 지지체층은, 상처부위에서 발생하는 삼출물을 그 내부로 흡수할 수 있도록 스폰지상의 형태를 취하는 것을 특징으로 하는 상처치료용 다층 드레싱재. - 제1항에 있어서,
상기 생체적합성 지지체층의 상부에는, 밀착층과 생체적합성 지지체층으로 구성된 적층체를 피부에 고정시키기 위한 접착테이프가 더 구비된 것을 특징으로 하는 상처치료용 다층 드레싱재. - 제1항에 있어서,
상기 밀착층의 두께는 0.5mm 내지 2.0mm 인 것을 특징으로 하는 상처치료용 다층 드레싱재. - 제4항에 있어서,
상기 스톤지상을 이루는 생체적합성 지지체층의 공극율은 40% 내지 70%인 것을 특징으로 하는 상처치료용 다층 드레싱재. - 제7항에 있어서,
상기 생체적합성 지지체층의 두께는 3mm 내지 5mm인 것을 특징으로 하는 상처치료용 다층 드레싱재.
