The filter assembly 5 is installed in the ventilation channel 21. After the filter assembly 5 is installed in place, the reset member 4 is in a compressed state, and the positioning member 3 extends out of the plug 2 through the extension opening 23. The waterproof breathable membrane 6 is fixed to one end of the plug 2 located in the patient's body through a hollow screw cap.

[0059] During use, the fixing member 1 is secured to the patient's body with a nail. A waterproof, breathable membrane 6 is installed at one end of the plug 2. The reset member 4 is mounted on the positioning member 3. With the positioning member 3 installed in the installation channel 22, the filter assembly 5 is installed in the ventilation channel 21 of the plug 2. After the plug 2 is installed in the fixing member 1, the filter assembly 5 is tightened. During the tightening process, the filter assembly 5 drives the positioning member 3 out of the extension opening 23. Once extended, the positioning member 3 engages with the fixing member 1 to secure it. Once the positioning member 3 is secured, the reset member 4 is compressed.

[0060] When the patient's intestinal peristalsis produces gas, the gas is discharged outward through the air permeable channel 21 on the plug 2. During the discharge process, the gas is filtered by the filter component 5.

[0061] When defecation is required, the filter assembly 5 is unscrewed, the reset member 4 is reset, and the positioning member 3 is driven to be retracted into the plug 2, and then the plug 2 is taken out from the fixing member 1.
