Figure 1-8As shown, a mounting port 2 is opened on the mattress 1, and a seat cushion 3 is installed above the mounting port 2. The defecation port 5 of the seat cushion 3 is used for defecation when needed after the seat cushion 3 conforms to the user's buttocks. The collection box 4 and the mattress 1 are connected by a corresponding connecting rod, so that the first connecting port of the collection box 4 corresponds to the defecation port 5. A monitoring mechanism is set between the container 6 and the collection box 4 to monitor the weight change of the container 6. The sewage pipe 8 of the container 6 runs through the container 6 and the collection box 4. The sewage pipe 8 only plays a role in conveying and does not support the container 6, so as not to affect the weight change of the container 6. The control device controls the state of the electric valve 9 according to the feedback of the monitoring mechanism. The electric valve 9 is commercially available. It is connected to the control device, so that the control device can control the state of the electric valve 9 according to the feedback of the monitoring mechanism, so as to discharge the excrement in the container 6 and meet the defecation needs of disabled people who are bedridden for a long time.

[0015] In some embodiments, the bottom of the seat cushion 3 is provided with an inner insert 10, and the inner insert 10 is connected to the mattress 1. For example... Figure 1-8 As shown, the inner insert 10 is made of titanium-nickel alloy. Multiple inserts are installed at the bottom of the cushion 3 to increase friction between it and the mattress 1 and to provide mounting points for the cushion 3. The inner insert 10 and the mattress 1 can be connected by bolts or snaps to ensure stability during use. The cushion 3 is made of memory foam and coated with medical-grade silicone gel to reduce skin friction damage. The cushion 3 is designed to fit the human buttocks with an ischial support area, a gluteal muscle buffer area, and a groin contact area, corresponding to the ischial tuberosity and surrounding bony prominences, the main area of ​​the gluteus maximus, and the gluteal crease and perianal curvature, respectively, making it more biomimetic and more comfortable to use.

[0016] In some embodiments, a container lid is further provided above the second connecting port 7 of the container 6, and slide rails 12 are provided along both sides of the second connecting port 7. Sliding portions 13 are respectively provided on both sides of the container lid, and the two sliding portions 13 of the container 6 are slidably connected to the slide rails 12. For example...

For example... Figure 1-8 As shown, an annular sealing ring 15 is installed in the annular limiting groove 14. When the container lid is closed above the second connecting port 7, the annular sealing ring 15 protrudes from the annular limiting groove 14, so that the annular sealing ring 15 and the container lid form an abutment relationship, which promotes the sealing inside the container 6 and prevents gas from escaping and affecting the environment. The annular sealing ring 15 is commercially available.

[0018] In some embodiments, the monitoring mechanism includes: a support plate 16 disposed at the bottom of the container 6; four half-bridge sensors 17 disposed between the bottom of the support plate 16 and the collection box 4; the half-bridge sensors 17 being connected to the processor; and an infrared sensor, a thermal sensor, an odor sensor, a sound sensor, a millimeter-wave radar, and a camera disposed near the second communication port, the infrared sensor, thermal sensor, odor sensor, sound sensor, millimeter-wave radar, and camera being connected to the processor. Figure 1-8 As shown, the support plate 16 is installed at the bottom of the container 6, and its connection method can be bonding, welding, or bolting. The half-bridge sensors 17 are commercially available. Four half-bridge sensors 17 are installed between the support plate 16 and the collection box 4 in four directions on the support plate 16. When the weight of the container 6 on it changes, the four half-bridge sensors will output corresponding voltage signals. By comparing the signals, the strain in different directions is obtained. Through the processor's calculation, the corresponding change in gravity is obtained. When it exceeds the corresponding threshold, the control device controls the electric valve 9 to open for discharge. The sensors also include corresponding infrared sensors installed inside the container near the second connection port for electrochemical identification to determine whether the container is clean. A millimeter-wave radar and a camera are also installed inside the container near the second connection port to capture images of the excrement, facilitating... The system analyzes features such as shape, color, and hardness. A thermal sensor is installed near the second connection point inside the container to detect temperature and dry the internal environment. An odor sensor is also installed near the second connection point to detect specific gas components released from excrement and use algorithms to determine the type of excretion. A sound sensor is also installed near the second connection point to collect defecation sounds and classify sound characteristics (such as frequency and duration) using an established sound model to identify abnormal excretion states such as diarrhea. The control device has a built-in processor, decision-making and control module, and data storage module. The remote management module connects to remote terminals (such as medical staff monitoring platforms and family members' mobile apps) via a wireless communication module (such as 5G or Wi-Fi). Millimeter-wave radar, cameras, and various sensors are all commercially available.
