A rubber tube is housed inside the sleeve, with the extended length of the rubber tube exceeding that of the sleeve. The end of the rubber tube is bendable. The sleeve is used to move the rubber tube, causing the front end of the rubber tube to form a hook shape, thus achieving the function of crushing and removing feces. One end of the sleeve is connected to the bedpan receiver, and the other end is connected to a hollow shaft motor. The rubber tube passes through the hollow shaft motor and is connected to a delivery pump, which is used to deliver laxative medication. The other side of the hollow shaft motor is connected to an electric actuator. A movable cleaning pipe is provided at the lower end of the baffle. A flushing pipe is connected to the end of the bedpan receiver away from the baffle. A transfer chamber is connected to the lower end of the bedpan receiver. Expanding devices are provided on both sides of the bedpan receiver.

[0006] The expansion device includes telescopic rods on both sides of the toilet bowl, and symmetrical expansion plates inside the toilet bowl. The telescopic ends of the telescopic rods penetrate the outer wall of the toilet bowl and are connected to the expansion plates. A pad can be added to the expansion plates to prevent skin scratches.

[0007] The toilet bowl is equipped with a camera mounted on the sleeve, allowing caregivers to monitor the situation inside the toilet bowl and adjust the position of components and the person.

[0008] The toilet bowl is equipped with an infrared rangefinder located below the sleeve. This allows for easy determination of the sleeve's movement distance, improving the accuracy of the rubber hose's extension and preventing injury to the user. Beneficial effects

[0009] This invention features a bedpan receiver, an expansion device, and a flexible, rotatable rubber tube. The tube allows for the injection of laxatives. The buttocks can be slightly opened, and the movable, rotatable rubber tube is inserted into the anus to crush or remove stool. The laxative is administered simultaneously, automatically assisting the elderly with defecation as needed. These multiple methods improve defecation efficiency and enhance elderly care.

The rubber tube 5 passes through the hollow shaft motor 6 and is connected to the delivery pump. The other side of the hollow shaft motor 6 is connected to the electric push rod 7. The lower end of the baffle 1 is provided with a movable cleaning pipe 9. The cleaning pipe 9 is slidably connected to the baffle 1 and is moved by the cylinder. The end of the toilet bowl 4 away from the baffle 1 is connected to the flushing pipe 10. The lower end of the toilet bowl 4 is connected to the transfer chamber 13. The two sides of the toilet bowl 4 are provided with expansion devices.

[0018] The toilet 4 is externally connected to a urination and defecation treatment device. The toilet 4 is detachably mounted on the bed frame via a fixing plate 31. The lower end of the toilet 4 is provided with a drain pipe 22, which is located at the lower end of the bed frame. The drain pipe 22 is connected in sequence to a sewage tank 24, a water vapor separator 23, and a deodorizing tank 25. The upper end of the deodorizing tank 25 is connected to a first air outlet conversion device 26. The first air outlet conversion device 26 is connected in sequence to a negative pressure machine 27 and a second air outlet conversion device 28. The second air outlet conversion device 28 is connected to a drying pipe on the toilet 4. A main unit box is provided on one side of the bed frame.

When the rubber tube 5 is about to contact the anus, the hollow shaft motor 6 is activated, causing the rubber tube 5 to rotate. At the same time, a laxative (such as an enema) is delivered through a delivery pump. The medication is sprayed out from the end outlet of the rubber tube 5, which is then inserted into the anus while rotating. After the rubber tube 5 has been inserted to a certain length, the extension of the electric push rod 7 is stopped. The rubber tube 5 injects the laxative into the anus, and at the same time, it rotates to pulverize hard, dry stools at the anus. If the end of the rubber tube 5 is curved, it can also carry away large amounts of stool. After defecation, the electric actuator 7 is reset, and the cylinder is activated to move the cleaning pipe 9 to clean the anus. After cleaning, the toilet bowl 4 is flushed through the flushing pipe 10, and the excrement enters the transfer chamber 13. Then, the pump 29 is activated to flush the toilet bowl 4 through the clean water tank 30. The excrement flows through the transfer chamber 13 and the defecation pipe 22 into the sewage tank 24. Solid excrement settles in the sewage tank 24, and then other excrement enters the water vapor separation tank 23 for water vapor separation and gas discharge. Then, it flows into the deodorizing tank 14. At the same time, the negative pressure machine 27 is activated to discharge the odor gas in the deodorizing tank 14 to prevent gas fermentation. Then, the buttocks are dried through the air drying pipe 29 by controlling the air outlet conversion device.
