503097 ___- _B?____ 五、發明說明(I ) 發明夕背曼 本發明一般係有關末期腎臟病的治療,更具體地說, 本發明係有關用於監測腹膜透析工作的方法與裝置。 吾人已知利用透析法維持腎功能已經下降到其腎臟不 再產生充分功能之患者,兩種主要的透析法係被使用··血液 透析與腹膜透析。 於血液透析法中,患者血液通過一部人工腎臟透析儀 ,機器內有一薄膜充當一顆人工腎臟,用以淨化血液。由 於血液透析是一種需要特殊機器的體外療法,因此存在著 若干缺點。 爲了克服血液透析的相關缺點,於是發展出腹膜透析 。腹膜透析利用患者本身的腹膜作爲半透膜,腹膜爲一種 腹部體腔的薄膜內襯。透過良好的灌注法,則腹膜能充當 天然之半透膜。 腹膜透析定期將無菌水溶液注入腹腔,此溶液稱爲腹 膜透析溶液或透析液。擴散交換及滲透交換係發生在溶液 和血液流穿天然人體薄膜之間,這些交換將腎臟正常排泄 之廢料移除,廢料一般由尿素和肌氨酸酐這類溶質組成。 腎臟亦維持其它物質如鈉和水的含量,其等必須利用透析 加以調節。水和溶質於透析期間通過腹膜之擴散作用稱爲 超過濾。 在連續的移動性腹膜透析中,透析溶液係利用一條導 管而被導入腹腔,透析液與血液之間的溶質交換係以擴散 達成,進一步之移除則藉由從血液提供一個適當的滲透梯 3 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) (請先閱讀背面之注意事項再填寫本頁) --------訂·--I I---* · 經濟部智慧財產局員工消費合作社印製 503097 經濟部智慧財產局員工消費合作社印製 A7 B7 五、發明說明(y) 度到透析液而達成,以容許水分自血液中流出。這讓體內 能達到適當的酸性基本成分、電解質和體液平衡’透析溶 液可直接經由導管從體腔引流出。 腹膜透析產生了一些重要問題’包括有:腹膜炎的危險 :效率較低,因此相較於血液透析增加了透析時間;以及 當使用自動化設備時,成本會增加。 一些腹膜透析上的變異已經被探討過,其中一種變異 即爲自動腹膜透析(“APD”)。APD使用一種稱爲循環控制 裝置之機器,於患者腹腔中自動地注入、滯留和排出腹膜 透析溶液。APD對於腹膜透析患者特別有吸引力,因爲其 能在患者夜間睡眠時施行,這使患者免除在其甦醒或工作 期間對持續之移動性腹膜透析的日間需求。 APD程序一般會持續數小時,其通常開始於用來排空 腹腔內用過之透析液的一個初始引流週期,APD程序接著 . 依次進行連續的注入、滯留和引流階段,每個注入/滯留/ 引流程序稱爲一個循環。APD可利用許多不同方式實施。 目前的APD系統於治療期間並不監測患者之腹膜內壓 ,現行系統僅限制一個卿筒可作用在連接於患者導管之管 線或管腔上的外部壓(或吸力)。若患者位於有時爲循環控 制裝置的系統下方,會有一個重力落差加諸於循環控制裝 置所能施於患者導管的正向注入壓力;反之,若患者位於 循環控制裝置上方,則重力落差會從循環控制裝置所能施 於患者導管的正向注入壓力開始減少。 腹膜內壓之監測爲有幫助的,因爲循環控制裝置在循 4 (請先閱讀背面之注意事項再填寫本頁) .¾^ ---------訂--------I . 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) 503097 經濟部智慧財產局員工消費合作社印製 A7 B7 五、發明說明(1 ) 環之間有時並不會完全將患者體液排出。具體而言,目前 可購得之循環控制裝置無法判斷患者是否吸入一些液體, 或者有些液體因患者或導管位置而無法從患者體內輕易地 引流。 於是’目前一些可購得之系統利用一個最小引流起始 値判定下次注入期間應該輸給患者的液體數量。舉例而言 ,當循環控制裝置判定患者處於”空的”狀態,若已經引流 注入容量的85%,則下次注入容量將爲loo% ;若僅引流 80%,則下次注入容量會被限制在95%。 當患者已經保持超過注入容量的一個預定百分率時, 會發出一個負的超過濾(uF)警示聲音,該預定百分率通常 是注入容量的50%或100%,然而,若患者並不覺得太滿 ,可不用理會這個警示。患者於單一治療期間能略過UF警 示的次數可由循環控制裝置的軟體加以限制,然而,uF警 示通常並不考慮亦可能連同透析液一起累積於腹腔內的實 際超濾液。 目前可購得之循環控制裝置於每次循環期間將患者腹 腔裝滿至預先程式化的某個特定容量,醫生會根據患者體 型、重量及其它因素指示此注入容量,然而因爲目前可獲 得之循環控制裝置無法監測腹膜內壓,醫生開處方時無法 將此因素納入考量。已知的是,腹膜內壓(IPP)對超過濾 (UF)亦有影響。 圖式1-3提供了目前APD系統的例示圖解,其等之中 無一嘗試監測腹膜內壓。 5 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) ----— II---Aw I · 11-----t----I----^_wi (請先閱讀背面之注意事項再填寫本頁) 503097 濟 部 智 慧 財 產 局 員 工 消 費 合 社 印 製 A7 B7 五、發明說明($ ) 參看圖式1,圖中例示了一個循環控制裝置l〇a,其包 括一個透析液容器11、一位患者12與一個引流容器13 , 來自容器11之透析液由於14表示之重力落差而注入患者 12體內,使用過的透析液則藉由15表示之引流落差從患 者12抽至引流容器13中。循環控制裝置i〇a並無監測患 者12腹膜內部壓力的感測器,一條獨立管腔16同時將透 析液容器11和引流容器13接至患者12身上。由循環控制 裝置l〇a操作之閥門17、18不是控制從容器11流向患者 12之透析液就是控制從患者12流向引流容器13之廢液。 翻至圖式2,於循環控制裝置10b中,引流容器13和 透析液容器11均裝在一個加壓室19內部,可將加壓室19 加壓或排空’以注入患者或予以引流。再者,閥門17、18 選擇性操作可控制透析液被輸入或排出患者12,而且並無 提供任何感測器偵測或監測患者12的腹膜內壓。 翻至圖式3 ’於系統l〇c中,透析液容器n係接至一 個唧筒21,唧筒接著將透析液容器u接至一條接於患者 12的共用管腔或導管16。23處提供了一個液體流量控制 閥’並由循環控制裝置10c控制。引流容器丨3亦接至一個 啷筒24,啷筒依序將引流容器13接至管腔16。25處亦提 供了一個控制閥。 圖式1-3巾例不之循環控制裝置i〇a」〇c的引流和注 入速轉_力落差(酬式呢作用綠、者賴w上的 吸力或壓力(見圖式2及3)決定。〜般而言,由於壓力不是 由重力落差決定就是由圖式2之加壓室_於患者管線16 I ^--------^--------- (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 503097 Λ7 B7 五、發明說明(< ) 另一端產生的壓力或吸力決定,循環控制裝置l〇a-l〇c無 法最佳化注入速率或引流速率。因此,若不測量腹膜內壓 或想出一個估計該壓力之方式的話,則難以最佳化引流或 注入速率。於圖式3之循環控制裝置i〇a_1〇c範例中,由 於缺乏任何壓力讀數,引流或注入速率之最佳化僅憑猜測 而來。 因此,需要一個改良式的循環控制裝置,其能測量治 療期間之包括引流、注入以及滯留期間的腹膜內壓。再者 ,需要一個改良式的循環控制裝置,使之能測量腹膜內壓 ,並於循環之間使用該數據更完整地引流一患者。再者, 需要一個改良式的循環控制裝置能精確地測量腹膜內壓以 免患者溢流。最後,需要一個改良式的循環控制裝置能同 時在注入和引流循環期間監測腹膜內壓,使患者的注入和 引流速度達到最佳化,並因此增加治療期間的滯留部分。 發明之槪要 本發明所提供之系統滿足了前述需求,其提供患者的 腹膜透析包括有一個接至患者的透析液容器,其第一壓力 感測器同軸地連接於其間;以及一個接至患者的引流容器 ,其第二壓力感測器以同軸地連接於其間。 在一項實施例中,系統更包括一個同軸地配置在透析 液容器與第一壓力感測器之間的第一嘟筒。 在一項實施例中,透析液於流體靜壓力差作用下從透 析液容器流入患者體內。 在一項實施例中,第二啣筒係同軸地配置在引流容器 7 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) (請先閱讀背面之注意事項再填寫本頁) 裝 訂---------' 503097 經濟部智慧財產局員工消費合作社印製 A7 B7 五、發明説明(b ) 與第二壓力感測器之間。 在一項實施例中,透析液於流體靜壓力差作用下從患 者流向引流容器。 在一項實施例中,第二壓力感測器測量一患者的腹膜 內壓,同時透析液從透析液容器流向患者。 在一項實施例中,第一壓力感測器會測量患者的腹膜 內壓,同時透析液從患者流向引流容器。 在一項實施例中,系統更包括有一條將透析液容器接 至第一感測器並將第一感測器接至一導管的第一管腔,以 及一條將引流容器接至第二感測器並將第二感測器接至該 導管的第二管腔,該導管則接至患者,自患者流向引流容 器之透析液將第一管腔的透析液排空,並使該透析液從第 一管腔經由第二管腔流向引流容器。 在一項實施例中,導管係一條雙腔型導管。 在一項實施例中,第一和第二感測器乃備援用的同軸 壓力/真空感測器。 在一項實施例中,本發明提供了一種爲患者進行透析 的方法,其步驟包括有:於患者腹膜中置入一條導管;提供 至少一個透析液容器;利用第一管腔將透析液容器接至導 管,該第一管腔具有一個同軸地配置在導管與透析液容器 之間的第一壓力感測器;提供至少一個引流容器,利用第 二管腔將引流容器接至導管,該第二管腔具有一個同軸地 配置在導管與引流容器之間的第二壓力感測器;將透析液 從透析液容器輸往患者腹膜,並以第二壓力感測器監測患 8 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公爱) " " (請先閱讀背面之注意事項再填寫本頁) 「裝 訂---------^_wi · 503097
