[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, an embodiment of the present invention provides a bagless abdominal stoma device, including: a fixing member 1, a plug 2, a positioning member 3, a reset member 4, a filtering component 5 and a waterproof and breathable membrane 6. A blocking opening 11 is provided in the middle of the fixing member 1. The plug 2 is installed in the blocking opening 11 of the fixing member 1. An air permeable channel 21 is provided inside the plug 2, an installation channel 22 is provided in the side wall of the plug 2, and an extending opening 23 communicating with the installation channel 22 is provided on the outer side wall of the plug 2. The positioning member 3 is installed in the installation channel 22. The reset member 4 is installed between the positioning member 3 and the side wall of the installation channel 22. The filtering component 5 is installed in the air permeable channel 21. After the filtering component 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 extending opening 23. The waterproof and breathable membrane 6 is fixed to one end of the plug 2 located inside the patient through a hollow screw cap.

[0031] During use, the fixing member 1 is fixed inside the patient by nails. The waterproof and breathable membrane 6 is installed at one end of the plug 2. The reset member 4 is installed on the positioning member 3. As the positioning member 3 is installed into the installation channel 22, the filtering component 5 is installed in the air permeable channel 21 of the plug 2. After the plug 2 is installed in the fixing member 1, the filtering component 5 is tightened. During the tightening process of the filtering component 5, the positioning member 3 is driven to extend out of the extending opening 23. After the positioning member 3 extends out, it cooperates with the fixing member 1 to achieve fixation. After the positioning member 3 is fixed, the reset member 4 is compressed.

[0032] When the patient's intestinal peristalsis generates gas, the gas is discharged outward through the air permeable channel 21 on the plug 2. During the discharge process, it is filtered by the filtering component 5.

[0033] When defecation is required, the filtering component 5 is unscrewed, the reset member 4 is reset, driving the positioning member 3 to retract into the plug 2, and then the plug 2 can be taken out of the fixing member 1.

[0034] During use, one end of the positioning member 3 inside the patient's body causes the extended part of the positioning member 3 to open under the pressure of feces. One end of the positioning member 3 outside the body is positioned through the filtering assembly 5, and the positioning member 3 is fixed under the pressure of feces and the positioning of the filtering assembly 5.

[0035] When defecating, when the positioning member 3 needs to be reset into the installation channel 22, the filtering assembly 5 is loosened, and the positioning member 3 returns to the installation channel 22 under the action of pressure, and then the plug 2 and the components inside the plug 2 can be taken out.

[0036] In one embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the plug 2 includes: a connecting rod 24, a connecting cylinder 25 and a plurality of connecting blocks 26. The connecting rod 24 is provided with a ventilation channel 21 along its axial direction. One end of the connecting rod 24 inside the patient's body has a curved surface structure. The connecting cylinder 25 is sleeved outside the connecting rod 24, and an installation channel 22 and an extending opening 23 are formed between the inner side wall of the connecting cylinder 25 and the outer side wall of the connecting rod 24. The plurality of connecting blocks 26 are evenly distributed on the inner side wall of the connecting cylinder 25, the connecting blocks 26 are threadedly connected with the connecting rod 24, and the reset member 4 is installed between the positioning member 3 and the connecting blocks 26.

[0037] During use, the reset member 4 is installed on the positioning member 3, and then the positioning member 3 is installed on the connecting rod 24. At this time, the positioning member 3 is located in the extending opening 23 and the installation channel 22, and the reset member 4 is in a normal state.

[0038] When plugging, the filtering assembly 5 is installed in the ventilation channel 21, and then the positioning member 3 is driven to move through the filtering assembly 5, so that the positioning member 3 extends out of the extending opening 23, and the positioning member 3 cooperates with the fixing member 1 to complete the fixing of the plug 2. At this time, the reset member 4 is in a compressed state.

[0039] When defecating is needed, the filtering assembly 5 is loosened, the reset member 4 is reset, so that the positioning member 3 returns to the extending opening 23 and the installation channel 22, which is convenient for taking out the plug 2. The plug 2 is set as a split structure, which is convenient for disassembly, cleaning and repeated use after use.

[0040] In one embodiment, as Figure 1 、 Figure 4As shown, the positioning member 3 includes: a positioning cylinder 31 and a positioning plate 33.

A relief groove 32 matching the connecting block 26 is provided at one end of the positioning cylinder 31. The reset member 4 is arranged between the connecting block 26 and the bottom of the relief groove 32. The positioning plate 33 is installed on the side of the positioning cylinder 31 where the relief groove 32 is provided. After the positioning member 3 is installed, the positioning cylinder 31 is located in the installation channel 22, and the positioning plate 33 can extend out through the opening 23.

[0041] During use, the reset member 4 is installed between the relief groove 32 and the mounting block. Then, the connecting cylinder 25 is sleeved outside the positioning cylinder 31, and finally, the positioning cylinder 31 is connected to the connecting rod 24. When fixing, the filtering assembly 5 is connected to the air-permeable channel 21 of the connecting rod 24, and then the positioning cylinder 31 is fixed through the filtering assembly 5, so that the positioning plate 33 provided on the connecting cylinder 25 extends out of the opening 23.

[0046] To facilitate the outer diameter of the connecting cylinder 25 to be the same as the diameter of the round head portion 243 after the positioning member 3 is installed, the connecting rod 24 is provided with three-part structure.

[0047] In one embodiment, asFigure 4 As shown, in order to facilitate the deformation of the positioning plate 33, the positioning plate 33 includes: a metal plate 331 and a skin-friendly layer 332. One end of the metal plate 331 is connected to the positioning cylinder 31. The skin-friendly layer 332 is wrapped and arranged outside the metal plate 331.

[0048] The metal plate 331 has a certain flexibility, which facilitates deformation during use. The skin-friendly layer 332 is latex or silica gel.
