A suction disc used for abutting against a dressing covering a wound is provided. The suction disc includes a base plate, a case, a negative pressure device, a first sensing device and a second sensing device. The base plate has a first surface and a second surface. The first surface abuts against the dressing. The base plate has a first opening and a second opening. The first opening and the second opening respectively communicate with the first surface. The case has a first chamber and a second chamber. The case connects with the second surface. The first chamber communicates with the first opening. The second chamber communicates with the second opening. The negative pressure device communicates with the second chamber, and is configured for providing a negative pressure to the second chamber. The first sensing device communicates with the first chamber. The second sensing device communicates with the second chamber.一種用於抵接覆蓋於傷口上之敷料的吸盤包含底板、殼體、負壓裝置、第一感測裝置與第二感測裝置。底板具有相對之第一表面與第二表面,第一表面用以抵接敷料,底板更具有至少一第一開口與至少一第二開口,第一開口與第二開口分別連通第一表面。殼體具有至少一第一腔室與至少一第二腔室,殼體連接第二表面,且第一腔室連通第一開口,第二腔室連通第二開口。負壓裝置連通第二腔室,負壓裝置配置以向第二腔室提供負壓。第一感測裝置連通第一腔室。第二感測裝置連通第二腔室。100‧‧‧吸盤110‧‧‧底板111‧‧‧第一表面112‧‧‧第二表面113‧‧‧第一開口114‧‧‧第二開口120‧‧‧殼體121‧‧‧第一腔室122‧‧‧第二腔室130‧‧‧負壓裝置140‧‧‧第一感測裝置150‧‧‧第二感測裝置160‧‧‧處理器200‧‧‧敷料300‧‧‧貼膜400‧‧‧病患500‧‧‧傷口X‧‧‧線段
