The air tube 34 is disposed on the inner wall of the silicone sleeve 31, and the urination tube 33 penetrates the silicone cover 32, with the urination tube 33 and silicone cover 32 fixedly connected. With the above configuration, relevant personnel place the polyester fabric ring 30 and silicone sleeve 31 on the glans penis. The air tube 34 is used to fix the position. When urinating, urine is discharged through the silicone cover 32. The urination tube 33 is used to transmit external air into the silicone cover 32 to assist the urine flow.

[0037] In operation, the following steps are taken: the person wearing the open-crotch pants 20 puts on their body, then guides the two elastic bands 21 into the buttocks, and places the two pull ropes 22 on the wheelchair seat 10. When the patient is male, the person wearing the polyester fabric ring 30 and the silicone sleeve 31 puts them on the glans penis. The air tube 34 is used to fix the position. When urinating, the urine is discharged through the silicone cover 32. The urination tube 33 is used to transmit external air into the silicone cover 32 to assist the urine flow.

[0038] When a patient needs to defecate, the airbag cushion 110 is connected to an external air pump. The external air pump draws air from the airbag cushion 110, causing it to move outward. The airbag cushion 110 is used to initially separate the buttocks. Because the front end of the airbag cushion 110 has an arc-shaped patch (not shown in the figure), which is made of polyester, the arc-shaped patch is placed on the inner thigh of the patient. The outer surface of the airbag cushion 110 is completely covered with a layer of polyester material (not shown in the figure). When the relevant personnel pull the pull rope 22, the pull rope 22 drives the elastic band 21 to further separate the buttocks. When the patient defecates and falls, the sensor in the annular defecation channel pipe 115 detects the object and transmits the working signal to the controller 118. The controller 118 controls the motor 1161 to start. The output shaft of the motor 1161 drives the door 1160 to open, allowing the waste to fall into the elastic drawstring garbage bag 1141.

[0039] After a period of defecation, the controller 118 controls the retractable spray head 1113 and the water pump 1111 to start. The retractable spray head 1113 extends into the annular defecation channel pipe 115, and the water pump 1111 draws water from the water tank 1110 into the connecting pipe 1112. The water in the connecting pipe 1112 is sprayed out through the retractable spray head 1113 to facilitate cleaning of the patient's buttocks, the annular defecation channel pipe 115, and the door 1160. After cleaning is completed, the controller 118 controls the retractable spray head 1113 and the water pump 1111 to shut down, and the retractable spray head 1113 retracts from the annular defecation channel pipe 115.

[0040] Subsequently, the controller 118 controls the motor 1161 to start in reverse. The motor 1161 drives the door 1160 to rotate in reverse. The door 1160 is used to block the annular defecation channel pipe 115. Then, the controller 118 controls the vacuum pump 119 to start. The vacuum pump 119 is used to suck out the water vapor in the annular defecation channel pipe 115.

[0041] Subsequently, relevant personnel controlled an external air pump to replenish gas into the airbag gasket 110, causing the airbag gasket 110 to deform and seal the hole in the middle of the airbag gasket 110, and further sealing the annular defecation channel pipe 115.

[0042] When the patient needs to lie down to rest, the relevant personnel release the buckle 8 from the lever 9, thereby flattening the two wheelchair armrests 12, the wheelchair backrest 13, the two third tubes 16, and the two fourth tubes 17. The wheelchair backrest 13 is supported by the wheelchair seat 10, while the wheelchair armrests 12 are supported by the limiting block 18.
