Systems, methods, and devices related to removing fluids from a patient are provided. In one instance, fluid is removed from the patient and delivered to a canister using reduced pressure. Reduced pressure is supplied to the canister via a reduced-pressure delivery conduit that includes a moisture processing device and a hydrophobic filter. The moisture processing device condenses moisture from the air to prevent condensation from occluding the hydrophobic filter. The moisture processing devices includes an expanded volume and one or more liquid-impermeable, vapor-permeable membranes. The liquid-impermeable, vapor-permeable membrane allows vapor to egress the moisture processing device. Other systems, methods, and devices are presented.本發明提供與自一患者移除流體相關之系統、方法及裝置。在一個實例中,使用減壓自該患者移除流體且將其遞送至一盒。經由包括一水氣處理裝置及一疏水性過濾器之一減壓遞送導管將減壓供應至該盒。該水氣處理裝置自空氣冷凝水氣以防止冷凝堵塞該疏水性過濾器。該等水氣處理裝置包括一經擴展體積及一或多個透氣防水隔膜。該透氣防水隔膜允許蒸汽排出該水氣處理裝置。本發明呈現其他系統、方法及裝置。100...系統102...水氣處理裝置103...減壓遞送導管104...組織部位105...患者106...導管107...流體接收器108...減壓介面109...醫療盒連接器110...引流體112...表皮114...密封部件116...附接裝置118...患者面向側120...介面部件122...第二減壓遞送導管124...第一壓力感測導管126...醫療盒連接器128...減壓單元130...殼體132...減壓殼體埠134...第二壓力感測導管136...壓力感測殼體埠138...盒140...遮罩142...患者埠144...減壓埠146...疏水性過濾器
