Description

Negative pressure sealing drainage device Technical Field The invention relates to the technical field of medical instruments, in particular to a negative pressure closed drainage device. Background The negative pressure closed drainage technology is a treatment method for promoting wound healing by applying negative pressure on the wound, and the technology drains wound seepage to the outside through the negative pressure effect, reduces the risk of wound infection, promotes granulation tissue generation and has been widely applied to the treatment of various acute and chronic wounds. In the prior art, as disclosed in chinese patent CN219646376U, a negative pressure sealing drainage device is disclosed, including setting up the drainage bag between porous cushion and sealing film, have confined drainage chamber in the drainage bag, the drainage bag towards one side evenly distributed of porous cushion have a plurality of with the drainage chamber intercommunication and be used for the drainage hole of drainage, still include with drainage bag fixed connection and with the drainage tube of drainage chamber intercommunication.
