Description

Technical Field

[0001] This utility model relates to the field of intelligent toilet equipment, specifically to a bed-based fecal collection and separation device. Background Technology

[0002] With the booming development of China's highway network and automotive industry, the causes of car accidents have become an increasingly important issue. Among them, mud and water sprayed from the sides of the tires of trucks or trailers, which affect the visibility of other drivers on the road, account for a large proportion of traffic accidents. Therefore, it is necessary to install water deflectors to block the splashed water and protect surrounding cars or pedestrians.

[0003] With the increasing aging of the population, the number of disabled people is constantly rising. Due to the loss of physical functions, disabled people are unable to independently complete basic daily activities, such as defecation, and require long-term care and attention. Traditional identification methods mainly rely on manpower, which is not only labor-intensive and inefficient, but also prone to misjudgment, making it difficult to meet the needs of disabled people, and also placing a heavy burden on their families.

[0004] Chinese utility model patent application No. 202311231967.6 discloses a feces collector. The monitoring system includes a collection unit, a monitoring unit, and a processing unit. The collection unit is configured to collect internal excrement and perform fecal sampling to obtain a fecal sample. The monitoring unit monitors the sample and, after obtaining monitoring data for one or more indicators, transmits the monitoring data to the processing unit for analysis and processing. The collection unit utilizes the principles of positive and negative air pressure to drive the user's feces, causing the feces to undergo a first processing process within a first pipe, thereby collecting a portion of the feces into a storage chamber as the sample. The system further includes performing a first and second monitoring process on the sample, and after the second monitoring process is completed, performing a second processing process on the storage chamber and the first pipe, thereby discharging the contents of the first pipe and the storage chamber through a second pipe.

[0005] However, for incontinent patients with incomplete spinal cord injury, who still retain some autonomy in urination, the risk of urinary tract infection is too high with catheterization. Therefore, a supine urinary bedpan allows patients to urinate while lying on their side. The above approach does not separate urine and feces. When monitoring water content, the mixture of feces and urine leads to inaccurate fecal monitoring results, thus requiring separation of urine and feces first. Furthermore, the lack of a recognition system makes timely monitoring and treatment after defecation impossible. Utility Model Content

Detailed Implementation

[0018] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings: Example: like Figures 1 to 8 As shown, this utility model provides a bedridden fecal collection and separation device, including a base 1, a bucket 2 for collecting urine and feces at the top of the base 1, a feces identification module 3 for identifying feces and monitoring feces shape, a guide mechanism 4 for separating feces and urine at the bottom wall of the bucket 2, wherein urine is discharged from the discharge part of the guide mechanism 4, and a sewage discharge mechanism 5 is provided on the side of the bucket 2 near the side that receives urine and feces, the sewage discharge mechanism 5 discharges feces from the bucket 2, the sewage discharge mechanism 5 is connected to the feces identification module 3, and the opening or closing of the sewage discharge mechanism 5 is controlled by the feces identification module 3.

[0019] The base 1 includes a load-bearing support 11 and a load-bearing bracket 12. The top of the load-bearing support 11 is detachably connected to the load-bearing bracket 12, and the top of the load-bearing bracket 12 is detachably connected to the bucket body 2. The top of the bucket body 2 is provided with a receiving interface 21 for discharging feces and urine into the bucket body 2. The bucket body 2 is provided with a sewage outlet 23 in the direction perpendicular to the axis of the receiving interface 21 for discharging feces.

[0020] Both the load-bearing support 11 and the load-bearing bracket 12 are made of metal and are connected by bolts to support the weight of the bucket 2 and the human body. The bucket 2 is made of ceramic or high-strength plastic. This application uses ceramic, which provides a smoother glaze. The bucket 2 and the load-bearing bracket 12 are connected by bolts. The entire bucket 2 is designed as a horizontal design for collecting feces. The human body can lie on top of the bucket 2. The human excretory organs are located at the urine and feces receiving area of ​​the bucket 2. The feces discharge of the bucket 2 is located on the side of the human body near the legs and feet. Feces or urine fall from the receiving interface 21 into the bottom wall of the bucket 2. Urine is discharged by the guide mechanism 4. Feces are detected by the feces recognition module 3. If feces are found, the feces recognition module 3 identifies the feces and analyzes its state, controlling the sewage discharge mechanism 5 to discharge the feces from the bucket 2.

[0021] As another embodiment, such as Figure 3 As shown, the fecal identification module 3 of this application includes a sensing unit 31, a data processing unit 32, and an execution control unit 33. The sensing unit 31 is electrically connected to the data processing unit 32, the data processing unit 32 is electrically connected to the execution control unit 33, the execution control unit 33 is electrically connected to the sewage discharge mechanism 5, and the execution control unit 33 controls the opening or closing of the sewage discharge mechanism 5.

[0022] The sensing unit 31 includes an excrement falling monitoring unit 311, a weight and temperature monitoring unit 312 and 312, and a space monitoring unit 313. The falling monitoring unit 311 includes an infrared beam sensor 3111 and an ultrasonic sensor 3112, with multiple infrared beam sensors 3111 and multiple ultrasonic sensors 3112 symmetrically distributed on the inner side wall of the tank 2. The weight and temperature monitoring unit includes a pressure sensor 3121 and a thermal sensor 3122, with multiple pressure sensors 3121 evenly arranged on the inner bottom wall of the tank 2, and multiple thermal sensors 3122 located within a 5-10 cm diameter range of the pressure sensors 3121. The space monitoring unit includes a gas sensor 3131 and a millimeter-wave radar 3132, with the gas sensor 3131 and the millimeter-wave radar 3132 located on both sides of the inner wall of the tank 2.

[0023] The sensing unit 31 is used to identify the presence and shape of feces, and transmits the identified data to the data processing unit 32. This unit is equipped with an excrement morphology feature database, which can identify the type of feces by comparing the reflected waveform of the millimeter-wave radar 3132 with the preset excrement feature template. It can also determine whether the feces are feces by analyzing the shape of the feces, thereby judging the patient's diet and gastrointestinal status. After the data processing unit 32 determines that it is feces, it transmits a command to the execution control unit 33. The execution control unit 33 controls the sewage discharge mechanism 5 to discharge sewage from the inside of the bucket 2, and discharges the feces from the bucket 2. The bucket 2 is equipped with a sewage discharge pipe at one end of the flow guiding mechanism 4 for sewage discharge.

[0024] The pressure sensor 3121 consists of an array of multiple sensors arranged at equal intervals. When the values ​​of multiple adjacent pressure sensors 3121 exceed the baseline pressure by 20% for 5 seconds or more, a gravity recognition signal is triggered and transmitted to the data processing system. Infrared beam sensors 3111 form a cross-monitoring network on the inner sidewall of the container 2, working in conjunction with ultrasonic sensors 3112 to monitor for fecal impact. A millimeter-wave radar 3132, located on the inner sidewall of the container 2, determines the shape of the feces. This comprehensive approach, combining data from multiple sensors to determine the presence and shape of feces, is more accurate than using a single sensor. It allows for immediate data transmission and precise identification of feces for timely cleaning, reducing the likelihood of bedsores in patients.

[0025] As another embodiment, such as Figures 4 to 8 As shown, the flow guiding mechanism 4 of this application includes a flow guiding plate 41 disposed on the inner bottom wall of the barrel 2. The flow guiding plate 41 is in close contact with the inner bottom wall of the barrel 2. A pressure sensor 3121 and a millimeter-wave radar 3132 are disposed on the flow guiding plate 41. A urination port 22 is provided at the end point of the flow guided by the flow guiding plate 41 in the barrel 2. An opening and closing component 42 is provided at the urination port 22 in the barrel 2. When urine flows through, the opening and closing component 42 opens, and urine is discharged from the urination port 22. When no urine flows through, the opening and closing component 42 closes. A flow guiding groove 411 is provided on the upper surface of the flow guiding plate 41. The depth of the flow guiding groove 411 gradually becomes shallower along the flow guiding direction. A side plate 412 is extended from the side of the flow guiding plate 41 near the urination port 22. The inclination angle of the side plate 412 is smaller than the inclination angle of the flow guiding plate 41.

[0026] The opening and closing assembly 42 includes an inclined groove 421 formed in the bottom wall of the inner wall of the barrel 2. The deeper side of the inclined groove 421 is connected to the urination port 22. An opening and closing plate 423 is rotatably connected in the inclined groove 421 via a rotating shaft 422. The rotating shaft 422 is in the inclined groove 421 and closer to the urination port 22. One end of the opening and closing plate 423 is spaced apart from the urination port 22, and the other end of the opening and closing plate 423 moves to abut against the edge of the inclined groove 421.

[0027] The guide plate 41 is made of ceramic with a smooth surface and is inclined, pointing in the direction of sewage discharge, with an inclination angle not exceeding 15 degrees. The opening and closing plate 423 is located below the end of the guide plate 41 on the drainage side. The guide channels 411 can converge to a single point at their endpoint or be arranged in parallel; this design uses the convergence method to reduce the number of opening and closing components 42. The gap between the opening and closing plate 423 and the urination port 22 is designed to prevent the arc-shaped trajectory formed by the end of the opening and closing plate 423 when rotating around the rotating shaft 422 from being blocked by the urination port 22. The end of the opening and closing plate 423 can be connected to the top edge of the urination port 22.

[0028] In actual use, there are different situations. For example, if there is only urine in the tank 2, the urine flows along the guide groove 411 on the guide plate 41 to the end of the guide groove 411. Since the urine flows along the guide plate 41 entirely by its own weight, the distance it is thrown forward when passing the side plate 412 is relatively short. It lands on the side of the opening and closing plate 423 near the urine outlet 22, and presses down the opening and closing plate 423 by its own weight and is discharged from the urine outlet 22. If only feces are present, the feces recognition module 3 can control the sewage discharge mechanism 5 to discharge the feces. When the sewage discharge mechanism discharges feces, pressure needs to be applied, whether by water flushing, gas flushing, or a combination of both, which requires greater pressure. Therefore, when the feces and the impact water flow fall from the side plate 412, the projection distance is farther. After jumping over the opening and closing plate 423 or flowing to the side of the opening and closing plate 423 away from the urination port 22, it continues to move forward. In order to prevent the feces from losing power after falling to the side of the opening and closing plate 423 away from the urination port 22, the opening and closing plate 423 is set as a plate parallel to the inner bottom wall of the barrel 2 on the side away from the urination port 22, and tilted towards the side closer to the urination port 22 at the rotation axis 422.

[0029] If urine and feces are produced simultaneously, the feces identification module needs several seconds to provide feedback. Urine will first flow along the guide channel 411 to the urination port 22. Subsequently, feces will be discharged by the sewage discharge mechanism 5.

[0030] As another embodiment, such as Figure 3 As shown, the sewage discharge mechanism 5 of this application includes a spray module 51 and a pneumatic module 52 connected to the execution control unit 33. The spray head of the spray module 51 and the output part of the pneumatic module 52 are located on the periphery inside the tank body 2, and are controlled by the execution control unit 33 to spray or output pneumatic pressure into the tank body 2.

[0031] The spray module 51 and the air pressure module 52 are existing technologies. The spray module 51 typically includes a water source and a pressure pump, which pressurizes water and sprays it from the side wall of the tank 2. Specifically, the side wall of the tank 2 is the side opposite to the direction of flow guided by the guide plate 41, and the spray head sprays water onto the side guided by the guide plate 41. The air pressure module 52 typically includes an air source and a compression tank, which pressurizes air and sprays it from the side wall of the tank 2, pushing the feces towards the side guided by the guide plate 41. During operation, the execution control unit 33 first controls the spray module 51 to spray water onto the inner wall of the tank 2 and the surface of the dirt, which serves to moisten, soften, and initially rinse. Then, the control unit 52 outputs a high-speed pulsed airflow to the same area, using the impact kinetic energy of the airflow to directly peel off the dirt and form strong turbulence in the tank to break up and suspend the dirt. The synergistic effect of water flow and airflow, with water lubrication reducing resistance and air propulsion accelerating the motion, together form a strong swirling force, which efficiently pushes the dirt toward and flushes it away from the drain outlet 23.

[0032] In addition to the spray module 51 and the air pressure module 52, a drying module can also be added. After cleaning is completed, the execution control unit 33 controls the opening of the drying module to dry the inside of the barrel 2.

[0033] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
