The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment, technical scheme described in the utility model is described in further detail.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5 and Fig. 6, Medical vacuum sealing drainage device, comprise porous Wound dressing 1, be arranged in the drain inner tube 2 in porous Wound dressing 1, drain inner tube 2 sidewalls are evenly equipped with a plurality of apertures 21, the switching interface 5 of being made by flexible material is arranged at porous Wound dressing 1 one sides, and the outer face of switching interface 5 protrudes from porous Wound dressing 1 surface, switching interface 5 is connected to porous Wound dressing 1 inside with drain inner tube 2, the top plug 41 of drain outer tube 4 is the cone shape with the dentation cutting edge, top plug 41 can insert and be sealedly attached in switching interface 5, drain outer tube 4 is connected with drain inner tube 2 by switching interface 5, drain outer tube 4 tail ends are connected with drainage container 6 by straight coupling 43, drainage container 6 is connected with negative pressure source 11 by conduit 7, be provided with syringe pipe 9 in drain outer tube 4, syringe pipe 9 tail ends stretch out from drain outer tube 4 end sidewalls, and syringe pipe 9 afterbodys have the seal cover 10 that can cover syringe pipe 9.
