When the patient is conscious of defecation, the sensor chip embedded under the hip pad is transmitted to the management center, and the computer immediately issues instructions: instantly open the absorption function key and discharge the excrement to the dirt bucket. Automatically open the warm water flushing function key to clean the excretion of urine and feces. Automatically open the drying and dehumidification function key, dry the private parts with a slight warm air, and patients will not appear red rash and pressure sores and other phenomena after long-term use.
