Description

201029630 六、發明說明: 【發明所屬之技術領域】 本發明大體而言係關於組織治療系统且詳言之,係關於 用於製造及使用一可傾倒及/或可注入凝膠或凝膠形成溶 液之方法、系統及組合物。 【先前技術】 臨床研究及實踐已表明:接近於組織位點提供減壓加強 且加速該組織位點處之新組織之生長。此現象之應用係為 ®數眾多的,但減壓之應用在治療傷口方面特別成功。此治 療(在醫學界中常常稱作「負壓創傷療法」、「減麼療 法」或真二療法」)&供諸多益處’包括上皮組織及皮 下組織自健康組織朝向組織位點之遷移、較快癒合及肉芽 組織之增加形成。通常,經由多孔襯墊或其他歧管裝置將 減壓施加至組織。多孔襯墊含有能夠將減壓分布至組織且 引導自組織汲取之流體的氣室(cell)或細孔。常常將多孔 P 襯墊併入具有促進治療之其他組份之敷料中。 通常,多孔襯墊或其他歧管裝置經設定大小以適合現有 傷口且以與傷口接觸之方式置放。接著隨著傷口開始癒合 且變得較小而週期地用較小片敷料替換襯墊或裝置。雖然 用多孔襯墊或其他歧管裝置之減壓療法之使用係極其成功 的,但此方法仍存在各種困難。舉例而言,可能難以獲得 充分填充傷口之具有適當寬度、長度或深度的多孔襯墊或 其他歧管裝置。另外,當移除多孔襯墊或其他歧管裝置 時,亦可能移除健康組織,藉此對組織位點造成進一步創 145647.doc 201029630 傷。 先前已提議使用生物可降解材料來製造多孔襯墊或其他 歧管裝置,因此取消將多孔襯墊或其他歧管裝置自組織位 點移除之需要。另外,其他人已嘗試各種方法來製造不同 形狀之生物可降解聚合物。然而,在所有此等方法中,預 先將生物可降解聚合物形成為一特定形狀。然而,個別傷 口具有不一致之形狀及大小。
Cavi Care 為由 Smith & Nephew Healthcare Limited生 產之泡沫敷料,該泡沫敷料為兩組份室溫硫化發泡體,其⑩ 中聚二乙基矽氧烷鹼與鉑催化劑及氫氣釋放劑混合,該等 組份在一起進行反應以形成傾倒至傷口上之泡沫,其中該 泡沫符合傷口之形狀。Cavi_CareTM並非為生物可降解的且 必須被移除並在一規則基礎上進行清洗。泡沫Cavi_CareTM 敷料並非多孔至足以與減壓療法一起使用。 因此,存在對符合傷口之確切形狀之生物可吸收性組合 物的需要,其中該組合物可用作敷料。本發明解決彼需 要。 參 【發明内容】 經由使用一種生物可吸收性組織敷料來滿足此等及其他 需要,該生物可吸收性組織敷料經設計以容易地符合組織 位點之大小及形狀。因此,在其最廣泛意義上,本發明產 生用於製造及使用各種組態之凝膠或凝膠形成溶液之組合 物、方法及系統。 根據本發明之一第一實施例為一種可流動生物可吸收性 145647.doc 201029630 組織敷料’其包括一氣體形成致孔劑及一凝膠或凝膠形成 溶液。 根據本發明之另一實施例為一種用於製備該上文所描述 之組織敷料的套組,該套組包括一第一容器中之一氣體形 成致孔劑混合物及一第二容器中之一凝膠或凝膠形成溶液 或用於一凝膠或凝膠形成溶液之脫水成份。 根據本發明之另一實施例為一種用該上文所描述之敷料 籲治療一哺乳動物之一組織位點的方法,該方法包括將該氣 體形成致孔劑與該凝膠或凝膠形成溶液混合以產生一可流 動泡沫型混合物,接著在該混合物發泡的同時將該泡沫型 混合物遞送至該組織位點上。 根據本發明之另一實施例為一種用於對一組織位點施加 一減壓組織治療之減壓遞送系統,該減壓遞送系統包括該 上文所描述之套組、一減壓源,及一歧管。在此等實施例 中,該歧管包含一減壓遞送管,其中該減壓管包含一近 Φ 端、一遠端及一延伸穿過該管之内腔,其中該近端與該減 壓源流體連通且該遠端與該敷料流體連通。 本發明之其他目標、特徵及優點將參考以下之諸圖式及 詳細描述而變得顯而易見。 【實施方式】 充分详細地描述此等實施例以使得熟習此項技術者能夠 實踐本發明,且應理解,可利用其他實施例且可在不偏離 本發明之精神或範疇的情況下作出邏輯結構、機械、電力 及化學改變。為了避免對於使得熟習此項技術者能夠實踐 145647.doc 201029630 本文中所描述之實施例而言不必要的細節,該描述可省略 熟習此項技術者已知之特定資訊。因此,以下詳細描述不 應以限制性意義加以理解,且說明性實施例之範疇僅藉由 附加申請專利範圍來界定。
在此說明書之情況下,術語「減壓」大體上指代小於經 受治療之組織位點處之環境壓力的壓力。在大多數狀況 下,此減壓將小於患者所位於之位置之大氣壓。雖然術語 「真空」及「負壓」可用以描述施加至組織位點之壓力, 但施加至組織位點之實際壓力可顯著大於正常地與絕對真 空相關聯之壓力。與此名稱一致,減壓或真空壓力之增加 指代絕對壓力之相對減小,而減壓或真空壓力之減小指代 絕對壓力之相對增加。描述組織之減壓治療之各種方法及 組合物描述於以下專利公開案中:WO 08091521A2、WO 08042481A2、WO 08036361A2、WO 08036359A2 > WO 08036162A2、WO 08013896A2、WO 07143060A2 ' WO 07133556A2、WO 07133555A2、WO 07106594A2、WO 07106592A2、WO 07106591A2、WO 07106590A2、WO 07106589A2 ' WO 07092397A2、WO 07067685A2 > WO 05033273A2 ' WO 05009488A2、WO 04105576A2、WO 04060148A2 > WO 03092620A2 ' WO 03018098A2 ' WO 0061206A1、WO 0038755A2、US 20070123895、US 7351250 、 US 7346945 、 US 7316672 、 US 7279612 、 US
