[0002] In the field of medical care, the daily care of paralyzed patients, especially excretion management, has always been a complex and sensitive issue. Due to their limited physical functions, paralyzed patients cannot control their excretions, which not only increases the difficulty and frequency of nursing care but also significantly impacts their quality of life and mental health. Traditional nursing methods often require frequent manual intervention, including cleaning excrement, personal hygiene, and changing clothing. These processes are not only time-consuming and labor-intensive but also pose a risk of infection due to improper handling, further exacerbating the patient's suffering and the burden on caregivers.

[0003] More importantly, the frequent nursing procedures and exposure during excrement handling often cause paralyzed patients to feel embarrassed and inferior, severely damaging their self-esteem and sense of privacy. Therefore, our company's development of a technology that can efficiently, safely, and humanely address the excretion problems of paralyzed patients has become a crucial issue that urgently needs to be addressed in the current medical and nursing field.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] See Figure 1 An excrement treatment and control system includes a sensing module, a controller, a pulverizing module, a waste collection module, a flushing module, a drying module, a power supply module, a negative pressure module, and a deodorization and noise reduction module. The power supply module is connected to an external 24V power supply and outputs power at different voltage values, such as 12V, 5V, and 3.3V. The sensing module, controller, pulverizing module, flushing module, drying module, and negative pressure module are all connected to the power supply module, which supplies them with power.

[0038] The sensing module, pulverizing module, rinsing module, drying module, and negative pressure module are all connected to the controller. The sensing module collects excretion signals and transmits them to the controller. The controller then controls the pulverizing, rinsing, drying, and negative pressure modules based on these signals. When the controller receives the excretion signal, it controls the pulverizing components to pulverize the excrement. The negative pressure module draws air from the collection tank to create a negative pressure, allowing the excrement to enter the tank more smoothly. A noise reduction and deodorization module is installed at the outlet of the negative pressure module to reduce noise and deodorize the air. After excretion is complete (either through a timer function on the controller or by setting a time limit after which the sensing module has not detected excrement), the controller controls the rinsing module to rinse the private parts and then controls the drying module to dry the body. The entire excretion process requires no additional personnel assistance, ensuring privacy and providing timely and hygienic treatment. It should be noted that the controller's response to a signal, such as turning another component on or off, and the controller's control according to a time sequence, are all conventional technologies in the field of automatic control.

[0039] See Figures 2 to 4 The power supply module includes a voltage regulator and filter component 11, a first step-down component 12 connected to the voltage regulator and filter component 11, a second step-down component 13 connected to the voltage regulator and filter component 11, and a third step-down component 14 connected to the second step-down component 13. The voltage regulator and filter component 11 regulates and filters the external 24V power supply to output a stable 24V power supply. The first step-down component 12 adjusts the 24V to an output 12V power supply. The second step-down component 13 adjusts the 24V to an output 5V power supply, and the third step-down component 14 adjusts the 5V to an output 3.3V power supply to power the controller and other modules.

[0040] See Figure 5 and Figure 6 In this embodiment, the controller uses STM32F407ZET6, which supports all Arm single-precision data processing instructions and data types, high-speed embedded memory (flash memory up to 1MB, SRAM up to 192KB), backup SRAM up to 4KB, and various enhanced I / O and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix, and also has timing function.

[0041] See Figure 7 The sensing module includes a sensing head 21 and an amplification component 22 connected to the sensing head 21. The sensing head 21 is positioned on the path of the excrement flow. The output of the amplification component 22 is connected to the AD_URINE pin of the controller. The excrement signal collected by the sensing head 21 is amplified and transmitted to the controller.

[0042] See Figure 8The pulverizing module includes a pulverizing drive component 31, a pulverizing adjustment component 32, and a pulverizing feedback component 33. The pulverizing drive component 31 is connected to the controller, the pulverizing adjustment component 32, and the pulverizing motor 34. The pulverizing drive component 31 is used to start and drive the pulverizing motor 34 according to the pulverizing signal RL_BACK_IO from the controller. The pulverizing adjustment component 32 is connected to the pulverizing drive component 31, the pulverizing feedback component 33, and the controller. The pulverizing adjustment component 32 is used to control the output power of the pulverizing motor 34 according to the adjustment signal PWM_BACK_IO from the controller. The pulverizing feedback component 33 is connected to the controller and is used to provide feedback on the power of the pulverizing motor to the controller.

[0043] More specifically, when the crushing motor 34 needs to be started, the controller's crushing signal RL_BACK_IO goes high, turning on transistor Q16, which in turn energizes the coil of relay K1. This causes the contacts of relay K1 to move, connecting the crushing motor 34 to the power supply, and the crushing motor 34 begins to operate. The controller's adjustment signal PWM_BACK_IO controls the PWM duty cycle, thereby controlling the on / off state of transistor Q20, which in turn controls the on / off state of MOSFET Q18, thus adjusting the power of the crushing motor. When MOSFET Q18 is on, the crushing feedback component 33 is connected to the crushing motor 34, collecting the electrical signals of the crushing motor 34 during operation and feeding them back to the controller AD_CUR_BACK.

[0044] See Figure 9 The rinsing module includes a heating component and a rinsing component. The heating component includes a heating element 41 housed in a water tank, a hot water control component 42 that controls the heating element 41 to turn on, and a hot water feedback component 43 connected to the heating element 41 when it is working. The hot water control component 41 controls the heating element 31 to work according to the rinsing signal PWM_MOTOR1_IO from the controller. Specifically, when rinsing is required, PWM_MOTOR1_IO outputs a high level, controlling transistor Q15 to turn on, pulling down the gate voltage of MOSFET Q14, causing MOSFET Q14 to turn off. This allows the 24V power supply to form a circuit with the heating element 41 after passing through resistor MR1 and LED5, and the heating element 41 begins to work. The hot water feedback component 43 feeds back the collected electrical signal to the controller.

[0045] The flushing assembly includes a pump connected to the controller and a flushing control assembly that controls the pump to turn on. The principle of the flushing control assembly is the same as that of the hot water control assembly 42, and will not be described again here.

[0046] See Figure 10The drying module includes a heating control component 51, a heating indicator component 52, and a heating feedback component 53. The control component is connected to the controller U5 and the heating fan 54. The heating control component starts the heating fan 54 according to the drying signal from the controller U5. The heating indicator component 52 is connected in parallel between the positive and negative poles of the heating fan 54 to indicate the working status of the heating fan. The heating feedback component 53 is connected to the heating indicator component 52 and the controller U5 to provide feedback on the power of the heating fan 54 to the controller U5.

[0047] Specifically, when drying the human body is required, the controller sends a high-level RL_BLOWER1_IO signal, which turns on transistor Q3, energizing the coil of relay K3. This, in turn, connects the heating fan 54, which is connected to the normally open contact of relay K3, and the heating fan 54 begins operation. A series resistor PR3 and a light-emitting diode (LED14) are connected in parallel across the positive and negative terminals of the heating fan 54 to indicate its operating status. The cathode of LED14 is grounded through a sampling resistor PR64, which is connected to the heating feedback component 53. The collected electrical signals are transmitted to the non-inverting and inverting inputs of operational amplifier U11A. The output of operational amplifier U11A is connected to the non-inverting input of amplifier U11B, and the inverting input of amplifier U11B is connected to its output. The output of amplifier U11B is connected to controller U5.

[0048] The negative pressure module includes a negative pressure fan connected to the sludge collection box, a negative pressure control component for controlling the operation of the negative pressure fan, a negative pressure indicator component connected in parallel across the positive and negative terminals of the negative pressure fan, and a negative pressure feedback component connected to the negative pressure indicator component. The negative pressure feedback component is used to feed back the power of the negative pressure fan to the controller. The negative pressure control component starts the negative pressure fan based on the negative pressure signal issued by the controller. In this embodiment, the specific circuit working principle of the negative pressure module is the same as that of the drying module, and can be referred to accordingly. Figure 10 .

[0049] This embodiment also provides an excrement disposal device for paralyzed patients, including the aforementioned excrement disposal control system, so that paralyzed patients can be cleaned up in a timely manner when excreting, which greatly reduces the intervention of nursing staff, reduces the burden on nursing staff, and also protects the dignity of patients.
