Abstract

A suction-cup type negative pressure drainage apparatus comprises a negative pressure sponge (1), and also comprises an embedded joint (5). The embedded joint (5) is embedded in the negative pressure sponge (1), and multichannel telescopic grooves (50) are formed in sidewalls of the embedded joint (5). The multichannel telescopic grooves (50) are formed in the sidewalls of the embedded joint (5). When the embedded joint (5) is under external force, due to the telescopic effect of the telescopic grooves (50), the embedded joint (5) does not squeeze a wound surface of a patient, so that discomfort of the patient can be relieved. In addition, an externally disposed drainage suction-cup (3) is disposed between the embedded joint (5) and an externally connected drainage tube (4), so that connection stability between the embedded joint (5) and the externally connected drainage tube (4) is improved due to the use of the externally disposed drainage suction-cup (3), the phenomenon of the falling off of the externally connected drainage tube (4) and the embedded joint (5) in use is avoided, and the defect of a poor effect by only using the suction-cup type suction is overcome.
