區域中餘和時’充分滲出物到達該等導電迴路,如下文將 進一步闡釋。第二導電迴路386具有一第一端子39〇及一第 157601.doc ⑧ -18- 201216930 一端子391。第二導電迴路386之第一端子39〇及第二端子 391藉由引線393及3 94電耦合至監視單元37〇且特定地與第 一LED 373相關聯。類似地,第三導電迴路388包含電耦合 至監視單兀370且與第三LED 375相關聯之引線395及396。 圖4A及圖4B展示第—導電迴路384,其代表其他導電迴 路386、388。第一導電迴路384含有形成有一或多個導電 間隙399之一導電路徑398。導電路徑398可裝設在一基座 379上。為幫助防止過早發出信號,一電絕緣層(未明確展 不)可覆蓋導電路徑398且僅在導電間隙399處具有孔隙。 將瞭解,當一離子流體環繞且覆蓋導電路徑398時,該離 子流體將電耦合導電間隙399 ^換言之,該離子流體充當 V電間隙399之一電橋接且允許導電路徑398載運一電流。 當充分載運電流時,監視單元37〇提供一信號,例如第一 LED 371。其他導電迴路386、388係類似。應瞭解雖然 展示三個導電迴路384、386及388,但可使用任一數目個 導電迴路。可使用多個導電迴路在不同位置處估定敷件 3〇1之飽和度且提供敷件3〇1之一逐漸升高滿度標度。 現在主要參考圖5,提供一偵測電路4〇〇之一說明性實施 例。可使用眾多電路設計且偵測電路4〇〇僅係其一者之一 說明性實施例。偵測電路4〇〇可包含在監視單元37〇中。偵 測單元400可經組態以回應於流過第一端子385及第二端子 387之一電流而給一 LED 4〇2供電’從而指示如一接通的傳 導或導電路徑所感測之敷件301中之滲出物。舉例而言’ 偵測電路400可提供一導電迴路,其回應於由在第一端子 157601.doc -19· 201216930 3 85與第二端子387之間傳遞之一小電流啟動而自一電池 401供應一電壓至LED 402。 偵測電路400可利用至少兩個電容器404及406來回應於 穿過第一端子385及第二端子387之電流。偵測電路400中 之若干電阻器408、410、412、414、416、418及420產生 電壓差,該等電壓差與電容器404及406—起發揮作用以驅 動一 NPN電晶體422及一 PNP電晶體424以啟動LED 402。 橫跨第一端子385及第二端子387之一接通的導電路徑允 許穿過電阻器408之電流繞過電容器404。電流流過電阻器 410至NPN電晶體422之基極,而非穿過由電阻器412提供 之較高電阻路徑。進入NPN電晶體422之基極之電流放大 允許穿過電阻器414及416流入NPN電晶體422中之電流。 當穿過電阻器41 0之輸入信號相對於發射極輸出將基極拉 為高時,NPN電晶體422係「導通」。 當相對於發射極將接收穿過電阻器41 4之電流之基極拉 為低時,PNP電晶體424係「導通」。因此,穿過NPN電晶 體422之基極之電流啟動PNP電晶體424以放大至將電流供 應至電阻器41 8及LED 402之電流。因此,NPN電晶體422 及PNP電晶體424僅回應於第一端子385及第二端子387接 通一閉合電路或導電路徑而啟動以供應點亮LED 402之一 電流。 偵測電路400亦可包含用作一端子之一輸出426。輸出 426可傳遞透過電阻器420接收之一信號,該信號指示PNP 電晶體424已被啟動,藉此穿過LED 402供應電流。輸出 157601.doc • 20- ⑧ 201216930 可與-記錄或登錄裝置連通,該記錄或登錄裝置記錄

在其他實施例中,偵測電路400可由其他電流偵測電路 替換。偵測電路400之電阻、電容或其他特性可基於橫跨 第一端子385及第二端子387之讀取之敏感度及lED 4〇2之 電力需求而變化。在另一說明性實施例中,LED 4〇2可由 一視覺或數位指示器替換,該指示器基於穿過電阻器41 8 傳遞至該指示器之電流位準來指示敷件3〇1内之滲出物之 量或類型。該指示器可係經特定校準以提供聲訊、視覺或 觸覺回馈至一或多個使用者之一類比或數位元件。 根據另一說明性實施例,一電容感測器可位於敷件之一 外部上’例如在圖1中電極162展示於其上之密封件i i 1 上。该電容感測器具有量測最後填充之一位置處之電容之 一感測斷面。當液體到達與該感測斷面相對應之位置時, 敷件之與該電容感測器相關聯之部分之電容在該敷件内改 變’如填充感測器所經歷。因此,該電容感測器產生指示 敷件係飽和之一信號。 根據另一說明性實施例’將一染料放置在吸收劑層(例 157601 .doc -21 201216930 如,吸收劑層3 1 5)令’當變濕時,該染料提供一改變的視 覺外觀(或光學特性)。該視覺指示可係反差之一改變、色 彩之改變、亮度之改變、反射率之改變或其他視覺提示。 視覺外觀之改變可係人眼所察覺或僅一裝置(例如,一電 光偵測器)可察覺之一改變。該電光偵測器可偵測視覺外 觀之更細微改變。該電光彳貞測器接近於密封構件3 11附著 且可光學上偵測反差之改變並產生指示該改變之一信號。 因此’當吸收劑層3 1 5變為飽和時,該染料改變反差,光 學偵測器感測反差之改變且產生一滿信號。在另一實施例 中’可將染料放置在治療引流體(例如,引流體丨〇8)中。 根據又一說明性實施例,將金屬電容板放在吸收劑層 (例如,吸收劑層3 1 5)或附近,在兩個板之間具有界定之空 間。電容隨著離子流體填充該等板之間的空間而改變。當 +子/瓜體填充该專板之間的空間時,量測電容之改變且記 下該改變。 現在主要參考圖6,提供一減壓治療系統5〇〇之另一說明 性實施例之一示意圖。減壓治療系統500包含一傷口敷件 5〇ι,該傷口敷件可包含一引流體508及—吸收劑層515。 偵測裝置559與吸收劑層5 1 5相關聯且經組態以以電 :方式判定何時該吸收劑層(或其某—部分)係實質上飽

可包含位於-基地台573上之一無線通信與電力傳輸單元 572及一天線通彳§與處理單元574。無線通信與電力子系統 571類似於一射頻識別裝置(rfid)。藉由一無線信號纟乃自 無線通信與電力傳輸單元572傳輸電力至天線通信與處理 單元574,藉由耦合件576將該電力自天線通信與處理單元 574提供至電子偵測裝置559。 提供至電子偵測裝置559之電力可增大已經產生(例如, 由一賈法尼電池)之電力或(例如)為一電阻電路提供所有電 力。在任一事件中,電子偵測裝置559經組態以判定吸收 劑層5 1 5是否飽和或液體存在於吸收劑層5丨5内之可能程度 且用相關資訊產生一信號。該信號可藉由耦合件576遞送 至天線通信與處理單元574,自該天線通信與處理單元, 一無線信號575載運該資訊至無線通信與電子傳輸單元 572 ^無線通信與電力傳輸單元572可進一步處理該信號以
