After the negative pressure of the external drainage device starts to act, the unit pressure value caused by the negative pressure is reduced, the discomfort of the human body is reduced, the absorption effect is improved, and the liquid absorption sponge 4 can be made of sponge or various cotton materials (preferably medical nylon silk cotton). The liquid absorption sponge 4 can be a hydrophilic filler, which has the functions of quickly absorbing urine and hydrophobicity, and after the negative pressure starts to act, the urine is taken away from the liquid absorption sponge 4. The sponge has a spatial structure, forms a plurality of cavities, and the cavities have pores to allow liquid to flow in and out. The urine is absorbed by the liquid absorption sponge 4, and under the influence of the negative pressure of the external drainage device, the urine is collected into the liquid collection cavity 3 and then further discharged to the external collection device by the negative pressure conduit 5.

[0035] The liquid absorption sponge 4 is arranged in the shell 1, and the liquid absorption sponge 4 connects the negative pressure cavity 2 and the liquid collection cavity 3.
