Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a gastrointestinal flora sampling device. Background Art

[0002] The gastrointestinal microbiome refers to the community of microorganisms that live in our gastrointestinal tract, including bacteria, fungi, and viruses. These microorganisms form a symbiotic relationship with our bodies and participate in many important physiological functions, such as food digestion, energy metabolism, and immune regulation. However, an imbalance in the gastrointestinal microbiome can lead to a range of health problems, such as intestinal inflammation, obesity, diabetes, and cardiovascular disease. Therefore, timely understanding the health of the gastrointestinal microbiome is crucial for preventing and treating related diseases.

[0003] Studies have shown that the intestinal microbiome of some gastrointestinal tumor patients differs significantly from that of healthy controls. Characteristic changes in characteristic bacterial communities and their metabolites may serve as biomarkers for early screening and diagnosis of gastrointestinal tumors. For example, characteristic intestinal microorganisms such as Fusobacterium nucleatum (Fn) have been extensively studied in the diagnosis of colorectal cancer (CRC). Diagnostic models constructed using these characteristic microorganisms have high accuracy, with the area under the receiver operating characteristic curve (AUC) ranging from 0.80 to 0.98. Changes in the abundance of certain characteristic intestinal microorganisms are closely associated with the prognosis of gastrointestinal tumors. For example, in CRC patients, a higher abundance of Fn may indicate a poor prognosis. Other opportunistic pathogens, such as Prevotella, Bacteroides sp., and Dialister invisus, are also associated with a higher risk of CRC progression and mortality.

[0004] Based on the results of fecal microbiome and microbiome sequencing, more personalized treatment plans can be developed for patients with gastrointestinal tumors. For example, intervention measures targeting specific microorganisms may help improve the sensitivity of immunotherapy. Regular fecal microbiome and microbiome sequencing can monitor changes in the intestinal microbial community structure of patients with gastrointestinal tumors and promptly detect potential recurrence risks. With the continuous advancement of technology and in-depth research, the application of fecal microbiome and microbiome sequencing in the diagnosis and prognosis of gastrointestinal tumors will become more extensive and in-depth. Future research can further explore the interaction mechanism between microorganisms and tumors, as well as develop more sensitive and specific biomarkers.

[0005] Gastrointestinal microbiome sampling technology analyzes the types, numbers, and distribution of microorganisms within the gastrointestinal tract to understand the health of the gastrointestinal flora. Sampling and analysis can identify potential gastrointestinal flora imbalances, allowing timely adjustments to maintain gastrointestinal health. This technology is crucial for studying the pathogenesis of gastrointestinal diseases, developing personalized treatment plans, and evaluating treatment effectiveness.

[0006] Feces is the main sample source for gastrointestinal flora testing, and its sampling method is crucial to the accuracy of the test results. The existing sampling scheme mainly adopts the natural defecation sampling method, and its steps are: make sure that the ice bag in the sampling bag has been placed in the freezer of the refrigerator for pre-cooling, and stick the label paper on the stool collection tube and ziplock bag. Try to empty the urine before defecation to avoid urine contamination of the fecal sample. After defecation, use a sterile spoon or a special collection tool to cut off a spoonful (about the size of a soybean) from the middle of the stool as a sample. Place the collected fecal sample in a sterile collection tube, tighten the lid, place it in a ziplock bag, and then place it in an insulation bag together with the pre-cooled ice bag. Make sure to send the sample back to the laboratory for processing within 24 hours.

[0007] The above process often requires patients to perform it themselves. Due to the patient's mobility, some patients have difficulty in sampling. In addition, the existing device does not have a self-cleaning function and is difficult to reuse, which undoubtedly increases the cost of using the device. Summary of the Invention

[0008] In order to solve the above problems, the present invention provides a gastrointestinal flora sampling device for reducing the difficulty of feces sampling.

[0009] To achieve the above-mentioned object, the technical solution of the present invention is as follows: a gastrointestinal flora sampling device, comprising a collection component, the collection component is used to collect patient feces, the collection component is connected to a classification component, the classification component is used to divide and transport feces, and the classification component is also used to self-clean during the transportation of feces, the output end of the classification component is connected to a sampling component and a processing component, the sampling component is used to store feces for gastrointestinal flora examination, and the processing component is used to process feces not used for gastrointestinal flora examination;

[0010] Also included is a control system, the control system is used to obtain the sample volume required by the patient, and the control system is also used to determine the morphology of each group of feces in the classification component;

[0011] When the feces are solid, the control system determines whether there is mucus or pus and blood in each group of feces, and controls the classification component to give priority to sampling feces with mucus or pus and blood, then randomly selects feces from different groups for sampling, and controls the processing component to process feces that cannot be used for gastrointestinal flora examination;

[0012] When the feces are in liquid form, the control system determines whether each group of feces is full, and controls the classification component to work after the group of feces closest to the collection component is full, and determines whether each piece of feces can be used for gastrointestinal flora examination. When the feces can be used for gastrointestinal flora examination, the sampling component is controlled to sample the group of feces. When the feces cannot be used for gastrointestinal flora examination, the classification component and the processing component are controlled to work to process the feces.

[0013] Furthermore, the classification component includes a fixed disk, a first transmission motor and a hose made of transparent material. The hose is wrapped around the fixed disk. The input end of the hose is connected to the collection component, and a first solenoid valve is provided at the connection between the hose and the collection component. The sampling component and the processing component are both connected to the output end of the hose, and a second solenoid valve is provided at the connection between the sampling component and the processing component and the hose. The output end of the first transmission motor is coaxially fixedly connected to a rotating rod, and a plurality of extrusion rods are provided on the side wall of the rotating rod. The extrusion rods are evenly arranged along the circumference of the rotating rod. The extrusion rods are used to squeeze the hose. The control system controls the operation of the first transmission motor and the second solenoid valve according to whether the feces can be used for gastrointestinal flora inspection.

[0014] Furthermore, the processing component includes an incineration chamber, which is connected to the output end of the hose. A burner is provided in the incineration chamber, which is used to incinerate the feces in the incineration chamber. The control system controls the operation of the incinerator according to whether the feces can be used for gastrointestinal flora inspection.

[0015] Furthermore, the control system includes a camera and a controller, the camera is used to collect image information of the hose, and the controller is used to determine whether the feces meet the sampling standard based on the image information. When the feces are solid, the control system determines whether there is mucus or pus and blood in each group of feces, and controls the first electromagnetic valve and the first transmission motor to operate, so that feces with mucus or pus and blood are sampled and feces of different groups are randomly selected to enter the sampling component, and controls the second electromagnetic valve and the burner (12) to process feces that cannot be used for gastrointestinal flora examination;

[0016] When the feces are in liquid form, the control system determines whether each group of feces is full, and controls the first transmission motor to work after the group of feces closest to the collection component is full, and determines whether each piece of feces can be used for gastrointestinal flora examination. When the feces can be used for gastrointestinal flora examination, the sampling component is controlled to sample the group of feces. When the feces cannot be used for gastrointestinal flora examination, the first transmission motor and the incinerator are controlled to work to process the feces.

[0017] Furthermore, it also includes a cleaning component, which includes a water tank for storing cleaning liquid. The output end of the water tank is connected to a pump component, and the output end of the pump component is connected to the collection component. A nozzle is provided at the connection between the pump component and the collection component, and the nozzle is used to spray cleaning liquid into the collection component.

[0018] Furthermore, the controller is further configured to control the pump assembly to operate according to the image information when a group of feces closest to the hose in the image information is no longer increasing.

[0019] Furthermore, the cleaning assembly includes a film with reels at both ends, each wound around the film. The reels are fixedly connected to the collection assembly. A transmission assembly is provided on the film, configured to move the film along the sidewalls of the collection assembly. The controller is further configured to control the transmission assembly to operate when the group of feces closest to the hose in the image information stops increasing within a set time.

[0020] Furthermore, a closing component is provided on the collection component, which is used to close the connection between the collection component and the outside world. The closing component includes symmetrically arranged baffles, which are all slidingly connected to the collection component, and the sides of the baffles close to each other are fixedly connected to electromagnets.

[0021] Furthermore, the control system also includes an infrared sensor, which is used to obtain distance information between the patient and the acquisition component, and the controller controls the operation of the sealing component according to the distance information.

[0022] Furthermore, the control system also includes an angular velocity sensor, which is used to obtain angle information between the acquisition component and the horizontal plane. When the angle information is less than a set value and the distance information is greater than a set distance, the controller controls the closing component to work.

[0023] The technical principles and beneficial effects of the above scheme are as follows:

[0024] The design of the classification component in this solution uses an extrusion rod to drive the deformation of the hose to achieve even division of the feces, thereby realizing quantitative sampling according to the detection requirements. At the same time, since the even division of the feces is carried out synchronously with the patient's defecation process, it is easy to obtain whether the feces is in the front, middle or back section according to the position of the feces in the hose, which helps to evenly collect the feces and improve the reliability of the sample.

[0025] At the same time, when the feces are divided equally, the state of the feces in each area is judged through image acquisition, and feces containing blood concentration, mucus, etc. are preferentially sampled to ensure that representative samples are retained.

[0026] Compared with the existing technology, this solution does not require users to directly contact feces during the entire sample collection process, which can reduce the resistance of patients or caregivers during the sampling process, and can also prevent patients or caregivers from contaminating fecal samples during operation. And because this solution realizes automated sampling, it can avoid the situation where patients lack relevant knowledge reserves, resulting in ineffective fecal sampling, and can also reduce the difficulty of accompanying personnel in assisting patients with limited mobility to take samples on their beds. At the same time, it can also prevent patients from directly defecate into the toilet, which will cause the toilet to contaminate feces.

[0027] This solution uses a hose to transport feces, preventing it from coming into contact with the device's internal structure, which could affect its use and cause fecal contamination. Furthermore, as the hose is squeezed by the different extrusion rods, the inner walls of the hose come into close contact. The inner walls of the hose at the contact point push the feces to the sides. As the extrusion rods move, the feces is driven to the rear of the hose, achieving self-cleaning. Compared to existing technologies, this solution can initially complete the cleaning of the device's interior, reducing the number of steps required by the operator, while also enabling sustainable use and lowering the cost of each use.

[0028] This solution also processes feces that are not selected as samples through an incineration chamber, etc., further reducing the user's operating steps.

[0029] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] The following is further described in detail through specific implementation methods:

[0039] Example 1:

[0040] As attached Figure 1 -Attached Figure 4 As shown: A gastrointestinal flora sampling device, including a collection component, which is used to collect patient feces. In this embodiment, the sampling component includes a sampling cup 5, and the collection component is connected to a classification component 4, which is used to divide and transport feces. The classification component 4 is also used to self-clean during the transportation of feces. The classification component 4 includes a fixed disk 42, a first transmission motor 41 and a hose 3 made of a transparent material. The hose 3 is wound on the fixed disk 42, and the input end of the hose 3 is connected to the sampling cup 5, and a first solenoid valve is provided at the connection between the hose 3 and the sampling cup 5. The output end of the first transmission motor 41 is coaxially fixedly connected to a rotating rod 44, and a plurality of extrusion rods 43 are provided on the side wall of the rotating rod 44. The extrusion rods 43 are evenly arranged along the circumference of the rotating rod 44, and the extrusion rods 43 are used to squeeze the hose 3, and the input end of the hose 3 is connected to the output end of the sampling cup 5.

[0041] The output end of the classification component 4 is connected to the sampling component and the processing component 1. The sampling component is used to store feces for gastrointestinal flora examination. In this embodiment, the sampling component is a sampling tube 2, which is detachably connected to the hose 3. The processing component 1 is used to process feces that are not used for gastrointestinal flora examination. The processing component 1 includes an incineration chamber 11, which is connected to the output end of the hose 3. A burner 12 is provided in the incineration chamber 11, and the burner 12 is fixedly connected to the top wall of the incineration chamber 11 by bolts. The burner 12 is used to incinerate feces in the incineration chamber 11. The input end of the hose 3 is connected to the collection component, and the sampling component and the processing component 1 are both connected to the output end of the hose 3, and a second solenoid valve is provided at the connection between the sampling component and the processing component 1 and the hose 3.

[0042] It also includes a control system, which includes a camera and a controller. The camera is fixedly connected to the inner wall of the fixed plate 42 by bolts, and the controller is fixedly connected to the inner wall of the fixed plate 42 by bolts. The camera, the first solenoid valve, the second solenoid valve, the first transmission motor 41 and the burner 12 are all electrically connected to the controller. The camera is used to collect image information of the hose 3, and the controller is used to determine whether the feces meets the sampling standards based on the image information, and control the second solenoid valve, the first transmission motor 41 and the incinerator to operate according to whether the feces meets the sampling standards.

[0043] The specific implementation process is as follows: During use, a reasonable sampling position is selected for the patient according to the patient's physical condition, and then the input end of the sampling cup 5 is placed close to the patient's anus until the patient's skin is deformed, the input end of the sampling cup 5 is closed, and then the device is started.

[0044] When the first transmission motor 41 is not working, the extrusion rod 43 squeezes the hose 3, so that the space inside the part of the hose 3 located inside the fixed plate 42 is evenly divided into several chambers. Then, as the first transmission motor 41 works, the first transmission motor 41 drives the rotating rod 44 to rotate, and the rotating rod 44 drives the extrusion rod 43 to rotate around the axis of the rotating rod 44. The position where the extrusion rod 43 squeezes the hose 3 gradually moves as it moves, so that the chamber gradually moves toward the output end of the hose 3 following the rotation of the extrusion rod 43.

[0045] After the patient defecates, the feces naturally falls under the action of gravity, passes through the first solenoid valve and enters the hose 3. As the squeezing rod 43 moves, the feces entering the hose 3 are gradually cut off, and following the movement of the corresponding chamber, they are pushed by the squeezing rod 43 and gradually move to the output end of the hose 3. During this process, due to the design of the squeezing rod 43, the squeezing rod 43 squeezes the position where it contacts the hose 3, so that the inner wall of the hose 3 at this position is tightly attached. The hose 3 squeezes the feces attached to its wall, reducing the residue of feces on the wall of the hose 3.

[0046] As feces move along the hose 3, the camera continuously collects image information of the hose 3. Since the hose 3 is made of transparent material, the controller can evaluate the state of the feces inside the chamber based on the image information, such as the degree of dryness and color of the feces. Under normal circumstances, human feces are mostly long and strip-shaped, brown or yellowish-brown, and there will be no mucus, pus or blood on it.

[0047] When the patient's feces is generally solid, the controller selects feces samples according to the shape of the feces in each chamber during this process. For example, when there is mucus or pus and blood in the feces in a certain chamber, the feces in the chamber is first selected for sampling. For other feces that do not have abnormal conditions, feces in different chambers are randomly selected for sampling. Since the dimensions of the hose 3, the extrusion rod 43, the fixed disk 42 and the working power of the first transmission motor 41 are all known data, the approximate volume of the feces in each chamber can be calculated based on the above data. After all the feces enter the hose 3 and the feces in the chamber are in normal condition, the controller determines the amount of feces that needs to be sampled based on the volume of the feces entering the sampling tube 2 and the amount of samples required to be collected, and selects whether the feces in the chamber needs to be sampled based on the judgment result, thereby achieving the purpose of collecting an appropriate amount of samples according to the needs of the examination.

[0048] When the feces selected as the sample is about to reach the output end of the hose 3, the controller controls the second solenoid valve connected to the sampling tube 2 to open, and under the action of the squeezing rod 43 and gravity, the feces enters the collection tube; and when the feces not selected as the sample is about to reach the output end of the hose 3, the controller controls the second solenoid valve connected to the incineration chamber 11 to open, and at the same time controls the burner 12 to operate. After the feces enters the incineration chamber 11 under the action of the squeezing rod 43 and the stop, it is burned under the action of the burner 12, thereby achieving the processing of the feces.

[0049] When the patient's feces is liquid, the controller continuously determines the content of feces in each chamber based on the image information. Only after the chamber closest to the input end of the hose 3 is filled, the first transmission motor 41 is controlled to work, and the feces are driven to move in the hose 3 through the squeezing rod 43. During the movement of the feces, it is judged whether the feces can be sampled. If the chamber closest to the input end of the hose 3 still cannot reach the filled state within the set time, the patient's defecation is completed, and the controller closes the first solenoid valve to prevent the feces in the chamber from escaping due to the subsequent actions of the patient, etc., causing environmental pollution and affecting the patient's experience.

[0050] The design of the extrusion rod 43 in this solution squeezes the hose 3, thereby evenly dividing the feces within the hose 3. This even division of the feces allows for quantitative fecal collection, meeting the needs of different examinations. Simultaneously, as the extrusion rod 43 squeezes the hose 3, the sidewalls of the hose 3 squeeze against each other, causing the feces at the extrusion point to move into the two adjacent chambers under the action of pressure. After the feces has completely entered the hose 3, the first transmission motor 41 is kept operating for a certain period of time, allowing the extrusion rod 43 to clear the feces within the hose 3. When the next patient uses this device, the feces of that patient, left behind by the previous patient at the connection between the collection cup and the hose 3, is driven into the hose 3. As the extrusion rod 43 operates, it gradually moves to the output end of the hose 3. At this point, the controller can discard the feces at the front end during the initial test state to avoid contamination of fecal samples from previous and subsequent patients.

[0051] As the squeezing rod 43 squeezes the hose 3, the thickness of the feces gradually becomes thinner as the distance between the feces and the squeezing rod 43 increases. The controller can further detect the state of this part of the feces through image information to avoid objects hidden in the feces, such as food residues, from being sampled, which may affect subsequent detection and the accuracy of sampling.

[0052] Example 2:

[0053] As attached Figure 1 As shown, the difference from Example 1 is that the cleaning component 6 includes a water tank (not shown in the figure), which is used to store cleaning liquid. The output end of the water tank is connected to a pump component (not shown in the figure). In this embodiment, the pump component is a water pump, and the output end of the pump component is connected to the collection component. A nozzle 61 is provided at the connection between the pump component and the collection component. The nozzle 61 is used to spray cleaning liquid into the collection component. The pump component is electrically connected to the controller, and the controller is also used to control the operation of the pump component according to image information.

[0054] The cleaning component 6 also includes a film 63, and a shell 62 is provided at both ends of the film 63. The shell 62 is bonded and fixed to the outer wall of the collection cup and is connected. The inner wall of the shell 62 is rotatably connected to a reel 64, and both ends of the film 63 are wound on the reel 64. A transmission component is provided on the film 63, and the transmission component is used to drive the film 63 to move along the side wall of the collection component. The transmission component includes a second transmission motor (not shown in the figure) and a spring. The output end of the second transmission motor is coaxially welded and fixed to the reel 64 located below the film 63, the spring is welded and fixed to another reel 64, and the other end of the spring is welded and fixed to the inner wall of the shell 62, and the second transmission motor is fixed to the inner wall of the shell 62 by bolts. The controller is electrically connected to the second transmission motor, and the controller controls the operation of the second transmission motor according to image information.

[0055] The specific implementation process is as follows: During the use of this device, when the patient finishes defecation, the feces in the chamber closest to the input end of the hose 3 no longer increase. Therefore, according to the image information, when the feces in the chamber in the image information no longer increase, the patient's defecation is finished. At this time, the controller closes the first solenoid valve and starts the pump assembly to work for a certain period of time, so that the cleaning liquid is sprayed from the nozzle 61 into the collection cup to rinse and soak the feces in the collection cup. When all the feces in the hose 3 are discharged from the hose 3, the controller controls the first solenoid valve to open, and controls the second solenoid valve of the incineration chamber 11 to open and controls the burner 12 to work, so that the cleaning liquid dissolved with feces in the collection cup passes into the hose 3. The controller controls the first transmission motor 41 to work and discharge the cleaning liquid into the incineration chamber 11 to achieve cleaning of the inside of the device.

[0056] Compared with the existing technology, this solution achieves further cleaning of the device, avoiding the difficulty of completely closing the hose 3 due to wear of the extrusion rod 43, thereby causing feces residue in the hose 3, and further contaminating the feces specimens of the patients used subsequently. At the same time, for some patients with sticky or unformed feces, by cleaning the inner wall of the collection cup, it can also prevent the feces of these patients from sticking to the collection cup, increasing the workload of the operator.

[0057] At the same time, if the patient has poor mobility and cannot use squatting or sitting postures, the patient can be assisted to adopt a side-lying posture or the like when collecting feces in a posture that allows the hose 3 to droop naturally. At this time, since the hose 3 can be deformed, the accompanying personnel can adjust the positions of the fixed plate 42 and the incineration chamber 11 to achieve sampling of the patient's feces. During use, the sampling cup 5 needs to be tilted with the horizontal plane, and the film 63 is located on the lower side. During defecation, the patient's feces falls on the film 63, and the accompanying personnel starts the second transmission motor, which drives the reel 64 to rotate. As the reel 64 rotates, the film 63 carries the feces to the hose 3 , with the movement of the film 63, feces gradually accumulates at the position of the first solenoid valve. After the second transmission motor starts for a set time, the controller opens the first solenoid valve and controls the first transmission motor 41 to work. Since the feces block the input end of the hose 3, with the movement of the extrusion rod 43, negative pressure gradually appears in the chamber closest to the input end of the hose 3. Under the action of air pressure, the feces is sucked into the hose 3. Then the controller can judge and screen the feces through image information. The above steps are repeated until the second transmission motor works for a set time, at which point the controller controls the first solenoid valve to open, and no feces enters the hose 3.

[0058] Compared with the existing technology, this solution can collect feces from some patients with limited mobility, and during the collection process, there is no need for the accompanying personnel to come into contact with the patient's feces, which effectively reduces the accompanying personnel's resistance. At the same time, the design of the film 63 and the like can also prevent the feces of such patients from falling directly on the side wall of the sampling cup 5, requiring the accompanying personnel to adjust the position of the sampling cup 5 and the like. Since the effective time of the fecal sample is short, the design of the film 63 can achieve real-time movement of the patient's feces, shortening the steps and time for collecting feces from such patients and reducing the probability of fecal specimen failure. At the same time, through the connection between the sampling cup 5 and the shell 62, the feces above the film 63 can be cleaned, reducing the subsequent cleaning amount of the film 63 and the like. At the same time, in order to achieve continuous movement of the feces, the second transmission motor needs to drive the film 63 to rotate in the same direction, thereby preventing the feces of the patient who was sampling on his side from contaminating the feces of the subsequent patient, thereby improving the accuracy of the samples collected by this solution.

[0059] Example 3:

[0060] As attached Figure 1 As shown, the difference from Example 2 is that a closing component is further provided on the collection component, which is used to close the connection between the collection component and the outside world. The closing component includes symmetrically arranged baffles (not shown in the figure), which are all slidably connected to the top wall of the collection cup, and the sides of the baffles close to each other are fixedly connected to electromagnets by bolts.

[0061] The control system also includes an infrared sensor, which is fixedly connected to the top wall of any baffle by bolts. The infrared sensor and the solenoid valve are electrically connected to the controller. The infrared sensor is used to obtain distance information between the patient and the collection component. The controller controls the operation of the sealing component based on the distance information. The controller is also used to control the operation of the transmission component based on the distance information.

[0062] The control system also includes an angular velocity sensor, which is fixedly connected to the outer wall of the collection cup by bolts and electrically connected to the controller. The angular velocity sensor is used to obtain the angle information between the collection component and the horizontal plane. When the angle information is less than the set value and the distance information is greater than the set distance, the controller controls the closing component to work.

[0063] The specific implementation process is as follows: When using this device, the infrared sensor continuously collects the distance information between the patient and the collection cup. When the distance information gradually shrinks to the set size, the patient's buttocks have gradually approached the collection cup. The controller controls the electromagnet to work so that the two magnetic poles are the same, so that the two repel each other, pushing the baffle to move away from each other, so that the collection cup opens, and the patient can defecate into the collection cup. After defecation, the patient moves the collection cup away from his or her buttocks, and the distance information gradually increases again. At this time, the controller controls any electromagnet to change the magnetic pole, so that the two baffles attract each other and close the collection cup.

[0064] The design of the sealing component can prevent the collection cup from being contaminated when not in use, thereby contaminating the fecal sample entering the collection cup. It can also prevent external dust from contaminating the feces that have not yet entered the hose 3 in time after the sampling is completed. The design of the infrared sensor determines whether the patient is about to use the device by judging the position of the patient's buttocks, thereby realizing automatic opening and closing of the baffle, which is conducive to reducing the operating steps of the device and improving the convenience of the device. At the same time, it can also realize timely sealing of the collection cup after the patient defecates, shortening the time that feces are exposed to the air, thereby further reducing the probability of feces being contaminated, and can prevent the patient's hands or clothes from accidentally entering the collection cup when adjusting their posture after defecation, thereby dirtying their hands or clothes and causing resistance from the patient.

[0065] During the use of this device, the angular velocity sensor continuously obtains the angle information between the collection cup and the horizontal plane. According to the angle information, the controller can determine the posture of the patient in collecting feces. When the angle information is less than the set value, the collection cup is slightly tilted to the horizontal plane. At this time, it can be determined that the patient is in a side-lying state. At this time, according to the distance information, only when the distance information is greater than the set distance, that is, when the patient's buttocks is about to approach the input end of the collection cup, the collection cup is opened by the electromagnet for subsequent sampling. Compared with the existing technology, this solution can avoid the feces falling out of the gap between the collection cup and the patient's buttocks due to the large distance between the collection cup and the patient's buttocks during the side-lying sampling process, affecting the collection process and also causing contamination of the bed.

[0066] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
