Description

200826984 九、發明說明： 【實施方式】 參考圖1及圖3 ’為將減麼組織治療投與患者之組織部位 13，提供本發日狀-實施例之—減㈣送系統η。該減麼 輸送系統包括一與，輸送管19以流體連接之伸縮杲 15 ’減壓輸送管19又與一低輪廓傷口包紮用品25以流體連 接（圖2中說明省去該減星輸送管之整合系統）。伸縮果15經 由減壓輸送管19及包紮用品25將減壓輸送至組織部位13。 在ζ、、且4 位處維持減壓，從而促進該組織部位處之組織 微變形且促進新組織生長。 、f較佳為包括一波紋狀側壁3 1的圓筒狀手動操作 X波、、、文狀側壁包括複數個隆脊h及凹槽37，以便使伸 、、、泵u八縱軸壓縮。該伸縮泵進一步包括整體式連接於波 紋狀側壁之兩相對末端處的一第一端壁39及一第二端壁 或者，該伸縮泵可包括密封式連接於波紋狀侧壁之兩 相對末端處的第一及第二端帽43(參見圖3)。波紋狀側壁與 十的苐及第一端壁一起界定一内部腔室51，該内部腔 至之容積可變。在未壓縮位置時，伸縮泵之波紋壁處於其 自心伸展悲（亦即波紋仍存在）且内部腔室容積處於最大 值。在壓縮位置時，伸縮泵已經受壓縮力，從而使内部腔 至各積減少且使波紋線性密度增大。 、連接口 53較佳安置於伸縮栗之一端壁處以使内部腔室與 減壓輪送官流體連接。一傘形閥55及一鴨嘴形閥57與連接 才喿作連接以選擇性地使流體進入内部腔室或自内部腔 124275.doc 200826984 室排出。鴨嘴形閥提供自減壓輸送管至内部腔室之單向产 體流通。傘形閥提供自内部腔室至伸縮栗周圍環境大氣: 單向流體流通。在含有連接口之端壁對面之端壁内安置有 一類似傘形閥。 更具體參考圖3，靠近傘形閥安置—疏水輯器Η及一 f味過遽器63(例如木炭過滤器）。疏水過滤器防止内部腔 室：之任何液體經由傘形閥排出。臭味過濾器排除自㈣ 腔室經由傘形閥排出之任何氣體帶來的臭味。 與伸縮泵關聯之複數個閥選擇性地允許與内部腔室進行 机體互換。當伸縮泵初始起動至壓縮位置時（對端壁施加 手動壓縮力所致），内部腔室中之氣態流體經由該等傘形 閥中之或兩者排出。氣態流體通過臭味過濾器之後再排 出内部腔室。收縮管處於壓縮位置時，已彈性變形之波紋 壁試圖恢復其未壓縮狀態。當波紋壁向返回其未壓縮狀態 而移動時，内部腔室容積增大，致使内部腔室中壓力下降 (内部腔室充當封閉系統P1*V1=p2*V2)。内部腔室與環境 〇氣（組織部位處之壓力）之間的差壓致使氣態流體及液態 流體自減壓輸送管及傷口包紮用品吸入内部腔室。因此形 成組織部位處之減壓。在經完好密封之傷口包紮用品的情 况下，可在組織部位處維持此減壓。自組織部位吸出之流 體、、、二由鴨嘴形閥進入内部腔室。鴨嘴形閥防止該等流體排 出内部腔室。 伸縮管裝置之一目標在於輸送及維持組織部位處之減壓 直至内腔至充滿傷口滲出液。在有些情況下，伸縮泵可 124275.doc 200826984 到達未壓縮位置（初始起動後）而盖 +、、六分、 …、而内部腔室充滿傷口滲 出/夜及其他液體。在此情況下 f細泵可猎由再次對伸縮 泵之端壁施加壓縮力來重新起動。 沒勒*内部腔室容積再次下 降時，内部腔室中之氣態流體經由伞形間排出。疏水過濟 盗防止内部腔室中之液體排出。由於伸㈣包括一個以上 傘形閥，因此該泵可經重新起動而與其定向無關。
伸縮泵可包括安置於内部腔室中之吸收性發泡體以捕集 自組織部位移除之傷口渗出液及其他流體。此外，可在伸 縮泵内提供-單向膜以防止任何流體回流至内部腔室外。 參考圖4及5,在本發明之一實施例中，伸縮果可包括一 ^有波紋壁的靠外殼71。單―端帽73可滑動式容納於外 殼中且定位於波紋壁之上以便藉由按壓該端帽來壓縮波紋 壁。擎子75及突舌（tab)77可與外殼及端帽操作性關聯，以 在波紋壁到達壓縮位置時形成可聞，，卡嗒聲，，。或者，且參 考圖6-8，複數個掣子及一突舌可與外殼及端帽操作性關 聯，以在起動伸縮泵時產生合齒音。每一個別”卡嗒聲，，可 表示伸縮泵在彼瞬間能夠提供的限定差壓。可聞指示音亦 可伴隨視覺指示器79以向使用者傳達將提供多少差壓。 參考圖8，執行測試以量測與具有由不同硬度材料製成 之波紋壁之伸縮泵關聯的壓力衰減。儘管結果指示具有 Shore 65 A之材料所經歷的衰減較少，但此部分係由於傷 口包紮用品之密封得以改良。發現Shore 65 A材料能夠提 供125 mm Hg與150 mm Hg之間的差壓。該等壓力水準能 夠維持至少六小時。對於更高壓力而言，可使用硬度更高 124275.doc 200826984 之材料（諸如Shore 85A材料）。使用此類泵設計可能產生 250 mm Hg之壓力且可能甚至4〇〇 mm Hg以上之壓力。 應注意，儘管描述了伸縮泵，但可用任何手動操作泵 (包括不限於隔膜泵或活塞泵）來取代伸縮泵。在有些情況 下，可能需要使用電能起動（或設定）泵，但在大多數情況 下，該泵能夠由使用者手動操作而無需電能。 再參考圖1，低輪廓傷口包紮用品包括一管接頭81、一 水凝膠環83及一膜85。管接頭定位於減壓歧管上方以使得 官接頭之孔口與歧管處於流體連接。水凝膠環安置於管接 頭與患者之組織表面89(鄰近組織部位）之間。較佳由聚胺 基甲酸酯製成之膜黏附式施加於管接頭及患者之組織表面 以固定包紮用品使其與患者相抵且在包紮用品與患者之間 提供始、封。包紮用品之密封特性進一步由水凝膠環增強， 該環不僅與患者之組織表面相抵而密封，而且防止組織表 面在使用包紮用品期間受損。 歧管較佳為高度網狀開放氣室式發泡體。歧管可分配伸 縮泵所提供之減壓。應注意，可使用任何能夠分配減壓的 材料來替代開放氣室式發泡體。 參考圖9，整合傷口包紮用品111亦可與減壓輸送系統一 起使用。整合傷口包紮用品包括安置於一膜115上的水凝 膠113之大島狀物。膜較佳包括黏接劑117用作水凝膠之輔 助性密封物。一孔口 121安置於膜中且一孔口 123安置於水 凝膠中，以容許一適型管接頭125之貫穿連接。 參考圖10-12，在傷口包紮用品之另一實施例中，一超 124275.doc 200826984 低輪廓減壓輸送管135與包紮用品直接連接。輸送管相當 扁平且其橫截面為矩形’從而大大降低整個包紮用品在斑 該輸送管連接時之厚度。較佳地，在輸送管㈣提供波紋 137(參見圖12)以防止輸送管在壓力下癟塌。輸送管及波紋 可在單-製造過程中-同擠壓，或可在獨立製造過程之後 組裝。波紋之間界定複數個流道139。輸 水凝膝傾注在膜及輸送管上且使其膠凝而與膜#辅糟由將 經由上述應明白所提供之本發明具有明顯優點。儘管本 發明僅以其幾種形式展示，但本發明並不僅限於此，而容 許在不背離其精神的情況下對其作出多種變更及修改。 【圖式簡單說明】 圖1說明本發明之一實施例之具有手動可壓縮泵的減壓 治療系統之橫截面正視圖，該手動可壓縮泵由一減壓輸送 管與一減壓歧管流體相連通。 圖2描繪本發明之一實施例之具有手動可壓縮泵的減壓 治療系統之橫截面正視圖，該手動可壓縮泵與一減壓歧管 流體相連通。 圖3說明本發明之一實施例之手動可壓縮泵的分解透視 圖。 圖4描繪本發明之一實施例之手動可壓縮泵的透視圖。 圖5說明圖4之泵之橫截面透視圖。 圖6描繪安置於圖4之手動可壓縮泵中之定位組件的透視 圖’該定位組件具有複數個齒及一掣爪。 圖7說明圖6之定位組件之正視圖。 124275.doc 11 200826984 圖8描繪量測多㈣具有+同硬度值《可撓性壁之手動壓 縮式伸縮泵的壓力隨時間衰減之測試結果之曲線圖。 圖9說明本發明之一實施例之減壓包紮用品，其具有一 黏接膜、水凝膠及一管接頭。 圖10描繪圖9之與一低輪廓減壓輸送管流體相連通之減 壓包紮用品之俯視圖。 Γ
