Abstract

The development of medical textiles follows the historical evaluation of textile fibers. Functional textiles represent the revolutionary evolution of textiles in science and technology, crossing the traditional boundaries of the textile field to meet the diverse and complex needs of users. The microclimate between the human body skin and the textile is an important construct for evaluating the comfort performance of clothing, and functional textiles are mainly used to create this suitable microclimate. The wound dressing cares for the wound just like the textile protects the skin. A proper moist environment was maintained by control of the amount of wound exudation in order to make the wound heal quickly and effectively. The foam dressing, one of advanced wound dressings, is basically a high-absorbency dressing made of polyurethane. Foam dressings have developed the concept of functional textile, allowing them to effectively absorb exudate, not to soak the wound, and to remove without adhesion to tissue. Using recent 20 years’ (2000~2019) foam dressing patents in Derwent Innovation database, we analyze the foam dressing patent trends and observe the different nation and company strategy. By using International Patent Classification (IPC) and Cooperative Patent Classification (CPC) we analyze and compare the different technical characteristics and distribution. Finally, we analyze the patents in silicone-containing foam dressings and in different applications and technologies, including laminar structure, anti-infection, anti-inflammation, scar management, and wound detection sensors and monitors. We choose and analyze the most important patent family in the data, the KCI’s US8480605B2 US patent family. The US patent family started from two sets of US provisional cases and completed the first in 2009. After patent applications, multiple continuation, continuation-in-part, and divisional applications were used to consolidate the novelty basis of patents. Using patent map analysis, it was constructed that 45 family patents have 12 branches with 12 different technical cores.

摘要

醫療紡織品發展跟隨紡織品纖維歷史演進，機能性紡織品代表紡織品在科技上的革命性演進，跨越紡織品領域的傳統界限，滿足使用者多方面複雜的需求。人體與織品之間的微氣候，是評估服裝舒適性能的重要指標，而機能性紡織品可以營造合適的微氣候。敷料照顧傷口就如同織品保護皮膚，能維持傷口與敷料間合適的微氣候。控制傷口滲液量，維持傷口適當的濕潤環境，才能讓傷口快速與有效的癒合。先進傷口敷料中的泡綿敷料是由聚氨酯製成的高吸收性敷料，泡綿敷料發展出如機能性織品的概念，讓泡綿敷料具有吸收滲液、不浸潤傷口及移除不沾黏組織的特點。本研究使用Derwent Innovation資料庫二十年（2000~2019）之泡綿傷口敷料專利，利用國際專利分類及合作專利分類，分析含矽膠泡綿敷料的專利，於不同的應用與技術，包括層狀結構、抗感染抗發炎專利、疤痕照顧專利及傳感器監測傷口變化等應用。並挑選母體中最重要之專利家族，KCI公司的US8480605B2進行分析，從該專利家族的全球布局，美國專利家族的特殊布局態樣；美國專利以兩組美國臨時案為出發點，於2009年完成第一輪專利申請後，善用美國CA案、CIP案及DA案使專利之新穎性基礎得以鞏固，並利用專利地圖分析，得出45篇專利家族主要有12分支，各有不同的技術核心。
