A suction set is disclosed. The suction set includes a guide pipe, an engaged structure, a suction catheter, and a controller for suction set. The controller for suction has a main body, a spring, a piston, a ribbed axle, and a lid. The main body has an intake pipe and a discharge pipe. A sealed portion is formed on one side of the main body. The ribbed axle penetrates the piston from out to out. One end of the ribbed axle meets the lid and another end of the ribbed axle meets the spring. The intake pipe connects to discharge pipe when the piston is in the first position likewise the intake pipe doesn’t connect to discharge pipe when the piston is in the second position. The suction set of the instant disclosure has the characteristics of better airtightness.一種抽痰管按壓系統,包括一導管、一卡合結構、一抽痰管及一抽痰管控制器,該抽痰管控制器包括有一組裝管體、一彈性體、一中空閥體、一制動軸體及一蓋體,該組裝管體具有一輸入管及一輸出管,該組裝管體之一側形成有一密封端,該制動軸體穿設於該中空閥體且該制動軸體之兩端分別抵頂於該蓋體及該彈性體之另一端,當該中空閥體於第一位置時,阻隔該輸入管連通該輸出管,當該中空閥體於第二位置時,該輸入管連通於輸出管;藉此,該抽痰管按壓系統可提供較佳的氣密效果。1...抽痰管系統10...抽痰管按壓控制器101b...輸出管101h...密封端101i...密封端之底座104...蓋體104f...第一定位凹槽104h...磨擦部20...導管201...連通管201a...凸塊202...套管203...開關閥203c...止滑部204...注射結構204a...注射蓋204b...逆止閥204c...注射管30...卡合結構301...喉管接頭302...注射接頭40...抽痰管401...抽引管402...套環
