Description

TECHNICAL FIELD

[0001] The utility model relates to portable urine and stool parameter detection field, concretely relates to a portable urine and stool detection main part. BACKGROUND

[0002] At present, the morbidity of intestinal cancer and stomach cancer has risen to the 3rd and 4th in the ranking of cancer morbidity in the country. At the same time, the morbidity of kidney disease is as high as 10.8% of the total population, about 1.2 billion people. Most intestinal and stomach diseases and kidney diseases have no obvious symptoms in the early stage of the disease, resulting in the user delaying the treatment time and reducing the survival rate of patients.

[0003] However, most intestinal and stomach diseases and kidney diseases in the early stage of the disease often have intermittent or continuous abnormalities in some indicators of urine and stool, including the detection indicators of stool and urine. Through the discovery and continuous monitoring of these abnormal indicators, the discovery time of intestinal and stomach diseases and kidney diseases can be advanced with high probability.

[0004] However, due to the busy work and study of people or the lack of awareness of disease prevention of the elderly, people are unwilling to go to the hospital for regular physical examination when they have no obvious symptoms, or they are unwilling to go to the specialist for further examination when the physical examination has individual abnormal indicators. Even if they feel a little abnormal, it is difficult to achieve continuous monitoring of indicators due to the cumbersome procedures of hospital examination. In addition, if regular hospital visits for continuous monitoring of some abnormal indicators are required, it will cost a lot of money and increase the economic pressure on people, making it more difficult for people to continuously monitor abnormal indicators.

[0005] Therefore, if people can detect urine and stool indicators at home quickly, provide urine and stool indicator rapid detection instruments similar to blood glucose meters, blood pressure meters, blood oxygen meters, etc., the above-mentioned various shortcomings and obstacles can be overcome, and people can be willing to continuously monitor abnormal indicators to detect the existence of some diseases or monitor the development of diseases in advance, achieve the effect of disease screening, save a lot of time and cost for users, and also gain time for later treatment.

[0006] The market for home physiological indicator detection is huge. According to the data of Global Point of Care Testing Market Outlook 2022, the global POCT (not considering the market of COVID-19 detection) industry size was 97 billion US dollars in 2022, and it is expected to grow at a CAGR of 11.9% in the next four years, reaching more than 120 billion US dollars in 2024. The domestic market reached 119.7 billion yuan in 2022, with an annual growth rate of not less than 15.68%, and it is expected to exceed 170 billion yuan in 2024. At present, various platforms have also begun to establish home detection business, and some institutions have achieved sales of 800 million yuan in convenient detection. Therefore, home physiological indicator detection is a future development trend.

[0007] However, the current market for urine and feces detection is different from blood glucose meters, blood pressure meters, and blood oxygen meters. The special properties of urine and feces lead to user resistance to using related detection tools. In particular, the detection of feces is mostly solid, and it needs to be diluted with detection liquid. Users are easily affected by the strong and unpleasant odor and the appearance of the liquid sample, and some uncomfortable physiological phenomena such as vomiting may occur.

[0008] Alternatively, the design of the sampling tool is unreasonable, making it difficult to take samples, and the design of the detection tool is unreasonable, making it easy for urine and feces to stick to the user's hands or other places, causing the user's psychological discomfort and disgust.

[0009] Therefore, the applicant provides a portable urine and feces detection device, which is simply hung on both sides of the toilet or the toilet bowl by the bracket. The user normally uses the toilet, and the urine or feces produced by the user naturally falls to the top of the main structure of the portable urine and feces detection device, so as to be received by the detection assembly inside the main structure. Then the detection assembly automatically transmits the urine or feces liquid sample to the test strip, so that the test strip develops color. Then the display result of the test strip is identified, the detection result is automatically judged, and the indication light is directly displayed. After the detection is completed, the user lifts the entire portable urine and feces detection device from both sides of the toilet or the toilet bowl and throws it into the garbage can. The structure is simple, easy to operate, and not easy to get dirty. The detection result is intuitive.

[0010] However, when designing the main structure of the portable urine and feces detection device, a simple natural sampling method is selected. In addition, the amount of liquid sample required for the test of the test strip is small. If the amount of liquid sample is too much, it will cause the test strip to be completely soaked in the liquid sample, which may cause inaccurate test of the test strip. Therefore, the main structure needs to solve the technical problem of excessive amount of liquid sample received by the natural receiving method when designing the main structure. The internal structure of the main body needs to be able to control the amount of liquid sample received by the test strip.

[0011] In addition, the waterproof problem of the whole main body structure and the internal detection assembly also needs to be solved at the same time to protect the normal work of various electrical elements arranged inside the main body structure.

[0012] Therefore, it is necessary to further improve the main body structure of the portable urine and stool detection device to ensure that each main body structure of the portable urine and stool detection device can be effectively detected and has a high detection result accuracy. Utility model content

[0013] The utility model aims at providing a portable urine and stool detection main body to solve the technical problems that when the main body structure of the portable urine and stool detection device receives a large amount of urine or stool liquid sample, the liquid sample amount flowing to the test strip is easy to be excessive, and the main body structure is waterproof.

[0014] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0015] A portable urine and stool detection main body, including upper shell and lower shell, the upper shell and lower shell are sealed and clamped, the upper shell and lower shell are detachable, the upper shell and lower shell have cavities, detection assembly is installed in the cavity, the detection assembly includes liquid storage cavity and detection site, the liquid storage cavity is provided with lifting platform, the lifting platform is slidably connected with the inner wall of the liquid storage cavity, the first sealing ring is arranged between the lifting platform and the inner wall of the liquid storage cavity, which prevents the sampling liquid sample in the liquid storage cavity from leaking out of the gap between the lifting platform and the liquid storage cavity.

[0016] The side wall of the liquid storage cavity is provided with a liquid outlet, the liquid outlet is provided with an outwardly extending flow guide water absorbing strip, and the flow guide water absorbing strip is used for adsorbing and guiding the liquid sample flowing out of the liquid outlet to the detection site for sample detection.

[0017] The initial position of the lifting platform is below the liquid storage cavity, the working position of the lifting platform is above the liquid storage cavity and below the liquid outlet, and is close to the liquid outlet.

[0018] The top of the upper shell is provided with a urine and stool channel, the top of the liquid storage cavity is provided with a second sealing ring, the sealing ring abuts against the inner wall of the periphery of the urine and stool channel, the urine and stool channel is communicated with the liquid storage cavity, and the liquid sample can enter the inside of the liquid storage cavity through the urine and stool channel.

[0019] In the scheme, the upper shell and the lower shell are sealingly connected, which can ensure that the liquid sample can only enter the liquid storage cavity through the urine and stool channel, and the sealing ring can prevent the liquid sample of urine or stool from flowing into other areas in the cavity through the urine and stool channel, causing short circuit of the circuit board or damage of the electromechanical equipment. The combination of the two can achieve sufficient waterproof function, ensuring that the portable urine and stool detection main body can normally perform detection work; the flow guide and water absorption strip can use the diffusion effect of the material to adsorb and guide the liquid sample to the detection position, which can avoid a large amount of liquid sample from rapidly entering the detection position in a short time, which may cause structural impact on the test strip placed in the detection position or exceed the maximum liquid sample amount that the test strip can receive, thereby causing detection failure or inaccurate detection results.

[0020] The portable urine and stool detection main body in the scheme integrates the detection assembly in a sealed shell. During detection, urine or stool passes through the urine and stool channel and reaches the detection assembly for detection. Sampling and detection are performed inside and outside the shell. After detection is completed, the detection result is displayed by the indicator light, which is very intuitive. Manual judgment is not required to determine whether a line or two lines are displayed on the test paper and the meaning of the lines. Manual sampling is also not required, and the hands are not dirty.

[0021] As an implementation manner of the lifting function of the lifting platform, a lead screw is fixed at the bottom of the lifting platform, one end of the lead screw away from the lifting platform is rotationally connected with a base, and the base is fixedly connected with the inner bottom of the lower shell. The lead screw is driven by a transmission mechanism to rotate forward to ascend or rotate reversely to descend. The transmission mechanism comprises a second motor, the output end of the second motor is fixed with a driving gear, and correspondingly, a driven gear is connected with the lead screw. The driving gear can drive the driven gear to rotate forward or reversely, thereby realizing the rotation of the lead screw forward to ascend or reversely to descend. When the lead screw rotates forward to ascend, the lifting platform is pushed to ascend, the volume of the liquid storage cavity is reduced, and when the lead screw reversely rotates to descend, the lifting platform descends, and the volume of the liquid storage cavity is increased. When the volume of the liquid storage cavity is reduced, the liquid level of the liquid sample to be detected in the liquid storage cavity rises, and when the liquid level rises to the liquid outlet, the liquid sample to be detected flows out from the liquid outlet.

[0022] As a preferred scheme of the transmission mechanism, the transmission mechanism further comprises a first gear set and a second gear set. The first gear set comprises a first large gear and a first small gear, and the first large gear is fixedly connected with the first small gear and coaxially arranged. The second gear set comprises a second large gear and a second small gear, and the second large gear is fixedly connected with the second small gear and coaxially arranged. The driven gear is engaged with the first small gear, the first large gear is engaged with the second small gear, and the second large gear is engaged with the driving gear. When the driving gear rotates forward or reversely, it can in turn drive the second large gear, the second small gear, the first large gear and the first small gear to rotate forward or reversely, thereby driving the driven gear to rotate forward or reversely, and further driving the lead screw to rotate forward to ascend or reversely to descend.

[0023] The multi-stage gear transmission has the following purposes: through the combination of gears of different sizes, the change of rotation speed can be realized, the multi-stage gear transmission can provide more fine speed and position control, when the large gear and the small gear are engaged, the rotation speed of the output shaft can be changed, so that the lifting platform can accurately control the speed during lifting; in addition, due to the limited space of the lower shell, the required motion transmission is realized through the multi-stage gear transmission, so that the space can be more effectively utilized, and through the multi-stage gear transmission, the load can be dispersed to multiple gears, so that the load of a single gear can be reduced, the service life of the gear can be prolonged, and noise and vibration can be reduced by reducing direct contact; when the driven gear needs to move in the reverse direction, the multi-stage gear transmission can more easily realize this.

[0024] As a preferred solution for detection, the detection site is arranged in the lower shell, and the detection site includes a test paper slot fixed to the inner wall of the lower shell for placing test paper; a liquid receiving port is formed in the test paper slot, and the two ends of the flow guide water absorption strip are respectively fixed to the liquid receiving port and the liquid outlet; an installation site is arranged beside the test paper slot for installing a color sensor. The sensing end of the color sensor faces the test paper slot for sensing the detection line displayed on the test paper.

[0025] As a preferred solution for the flow guide water absorption strip, the flow guide water absorption strip is externally covered with a waterproof film, and the two ends of the waterproof film are respectively fixedly connected with the liquid receiving port and the liquid outlet. The waterproof film is used to avoid the situation that the flow guide water absorption strip falls off due to saturation of the liquid absorbed in the flow guide water absorption strip, causing detection failure, or the situation that liquid gathers at the low point of the flow guide water absorption strip, causing liquid droplets to fall from the flow guide water absorption strip to other places in the cavity, damaging various electrical elements in the cavity.

[0026] A specific structure is used to guide the reaction of the liquid sample and the test paper, that is, the liquid in the liquid storage cavity is absorbed by the flow guide water absorption strip through the liquid outlet and guided to the liquid receiving port to contact the test paper in the test paper slot, and the index is detected by using the colloidal gold test paper method. This method can control the accuracy of the reaction, and the flow guide water absorption strip is used instead of a water pipe, which can effectively control the flow of the liquid sample.

[0027] As a mounting method of the color sensor, a sensor bracket is mounted at the installation site, and a first window and a second window are formed in the sensor bracket. Correspondingly, the color sensor has a first sensing end and a second sensing end, the first sensing end corresponds to the position of the first window, and the second sensing end corresponds to the position of the second window, so as to facilitate sensing the color of the test paper.

[0028] In detection, the test paper detection adopts the colloidal gold method, and the basic principle is to reduce gold ions into colloidal gold particles by chemical reduction method. These particles are usually between 10-100 nanometers in diameter, have stable red appearance, and when detecting, liquid samples are added to the test strip, and the sample moves along the test strip under capillary action. Usually, a test line (T line) and a control line (C line) are provided on the test strip, and whether the detection target molecule is present or not is determined by judging whether the T line and the C line appear. The first sensing end and the second sensing end correspond to the positions of the T line or the C line on the test paper respectively, so as to facilitate reading of the detection result, and after the control circuit board judges the detection result, the on-off or color change of the indicator light is controlled.

[0029] As a preferred solution of the detection assembly, the detection assembly further comprises a stirring device; the stirring device extends into the liquid storage cavity for stirring the liquid sample in the liquid storage cavity; the stirring device comprises a first motor, and a propeller is fixed to an output end of the first motor; the propeller extends into the liquid storage cavity; and the first motor can drive the output end to rotate, thereby driving the propeller to rotate.

[0030] The stirring device is suitable for detection of the liquid sample of the stool, because the liquid sample of the stool is usually solid. In detection, the detection reagent is first dripped into the liquid storage cavity, and after the liquid sample of the stool falls into the liquid storage cavity, the stirring device is started to make the detection reagent and the liquid sample of the stool fully mixed. As the lifting platform rises, the liquid sample to be detected in the liquid storage cavity flows out from the liquid outlet. Since the flow guide water absorption strip is used, only liquid is enriched by the flow guide water absorption strip, and the solid liquid sample does not flow out.

[0031] As a preferred solution, a control circuit board is installed in the upper shell, temperature sensor mounting positions are arranged on the top of the upper shell on both sides of the urine and stool channel for installing temperature sensors, the temperature sensors are electrically connected with the control circuit board; a strip-shaped hole is formed in the upper shell, and an indicator light is installed in the strip-shaped hole; the detection assembly and the indicator light are respectively electrically connected with the control circuit board; when the urine or the stool falls into the urine and stool channel, the temperature sensor senses the temperature and transmits the temperature sensor signal to the control circuit board, and the control circuit board controls the detection circuit to be turned on, thereby starting the detection operation of the detection assembly; a switch button is arranged on the lower shell, one side of the switch button towards the inside of the shell corresponds to a power switch on the control circuit board, and the switch button extends out of the side wall of the lower shell, so as to facilitate operation of the operator.

[0032] As a preferred solution, a through hole is formed in the middle of the control circuit board, and the liquid storage cavity extends from the bottom of the inside of the shell through the through hole and extends to the urine and stool channel.

[0033] As preferred, the top of the upper shell is provided with a protective cover, which can cover the urine and stool passage, for protecting the main body structure during transportation or storage.

[0034] The portable urine and stool detection main body has the following beneficial effects: the upper shell and the lower shell are sealingly connected, so that liquid samples can only enter the liquid storage cavity through the urine and stool passage, and the sealing ring can prevent liquid samples of urine or stool from flowing into other areas in the cavity after passing through the urine and stool passage, so as to cause short circuit of the circuit board or damage of the electromechanical equipment, and the combination of the two can achieve sufficient waterproof function, so as to ensure that the portable urine and stool detection main body can normally perform detection work; the flow guide water absorption strip can use the diffusion effect of the material to adsorb and guide the liquid sample to the detection position, so as to avoid that a large amount of liquid sample rapidly enters the detection position in a short time, which may cause structural impact on the test strip placed in the detection position or exceed the maximum liquid sample amount that the test strip can receive, so as to cause detection failure or inaccurate detection result; the portable urine and stool detection main body can solve the technical problems that when the main body structure of the portable urine and stool detection device receives a large amount of liquid samples of urine or stool, the liquid sample amount flowing to the test strip is prone to be excessive, and the main body structure is waterproof.

DETAILED DESCRIPTION

[0045] In order to better understand the purpose, structure and function of the utility model, the utility model is described in further detail below in combination with the drawings.

[0046] The utility model can be applied to the field of portable urine and stool index detection, and solves the technical problems that when the main body structure of the portable urine and stool detection device receives a large amount of urine or stool liquid sample, the liquid sample amount flowing to the test paper strip is prone to be excessive, and the main body structure is waterproof.

[0047] Please refer to Figures 1 to 3 , based on the above-mentioned solved technical problem, the utility model discloses a kind of portable urine and stool detection main body, including upper shell 101 and lower shell 102, the upper shell 101 and lower shell 102 sealing clamping, the upper shell 101 and lower shell 102 can be detached, the upper shell 101 and lower shell 102 have cavity, detection assembly 300 is installed in the cavity, the detection assembly 300 includes liquid storage cavity 301 and detection site, the liquid storage cavity 301 is provided with lifting platform 304, the lifting platform 304 with the liquid storage cavity 301 inner wall slidingly connected, first sealing ring 307 is arranged between the lifting platform 304 and the liquid storage cavity 301 inner wall, for preventing the liquid sample in liquid storage cavity 301 from the gap between the lifting platform 304 and the liquid storage cavity 301 leakage;

[0048] The side wall of the liquid storage cavity 301 is provided with a liquid outlet 303, and an outwardly extending flow guide water absorbing strip 316 is arranged at the liquid outlet 303, which is used to absorb and guide the liquid sample flowing out of the liquid outlet 303 to the detection position for sample detection.

[0049] The initial position of the lifting platform 304 is below the liquid storage cavity 301, and the working position of the lifting platform 304 is above the liquid storage cavity 301 and below the liquid outlet 303, and is close to the liquid outlet 303.

[0050] The top of the upper shell 101 is provided with a urine and feces passage 105, and the top of the liquid storage cavity 301 is provided with a second sealing ring 317 which abuts against the inner wall of the outer periphery of the urine and feces passage 105. The urine and feces passage 105 is connected with the liquid storage cavity 301, and the liquid sample can enter the inside of the liquid storage cavity 301 through the urine and feces passage 105.

[0051] In this scheme, the upper shell 101 and the lower shell 102 are sealingly connected, which can ensure that the liquid sample can only enter the liquid storage cavity 301 through the urine and feces passage 105, and the first sealing ring 307 can prevent the liquid sample of urine or feces from flowing into other areas in the cavity after passing through the urine and feces passage 105, causing short circuit of the circuit board or damage of the electromechanical equipment. The combination of the two can achieve sufficient waterproof function, ensuring that the portable urine and feces detection main body can normally perform detection work. The flow guide water absorbing strip 316 can use the diffusion effect of the material to absorb and guide the liquid sample to the detection position, which can avoid a large amount of liquid sample from entering the detection position rapidly in a short time, which may cause structural impact on the test strip placed in the detection position or exceed the maximum liquid sample amount that the test strip can receive, causing detection failure or inaccurate detection results.

[0052] The portable urine and feces detection main body in this scheme integrates the detection assembly 300 in a sealed shell. During detection, urine or feces passes through the urine and feces passage 105 and reaches the detection assembly 300 for detection. Sampling and detection are performed inside and outside the shell. After detection is completed, the detection result is displayed by the indicator light 109, which is very intuitive. Manual judgment is not required to determine whether a line or two lines are displayed on the test paper and the meaning of the lines. Manual sampling is also not required, and the hands are not dirty.

[0053] The working process of the scheme is: when the home urine and stool detection is carried out, the portable urine and stool detection main body is simply hung on both sides of the toilet or the toilet bowl, and the normal toilet is used, the urine and stool passage 105 at the top of the main body is used to collect urine or stool, and then the detection assembly 300 is used for detection. In the initial state, the lifting platform 304 is located below the liquid storage cavity 301, and the urine liquid sample is collected in the liquid storage cavity 301. After the urine liquid sample is collected, the lifting platform 304 starts to rise to the working position, and the liquid level of the urine liquid sample is lifted, so that the urine can be discharged from the liquid outlet 303; after the detection is completed, the detection result is displayed by the indicator light 109, and the whole detection device is directly discarded in the garbage can.

[0054] As an implementation manner of the lifting function of the lifting platform 304, please refer to Figure 3 , the bottom of the lifting platform 304 is fixed with a lead screw 308, one end of the lead screw 308 away from the lifting platform 304 is rotatably connected with a base 309, and the base 309 is fixedly connected with the inner bottom of the lower shell 102; the lead screw 308 is driven by a transmission mechanism to rotate forward to rise or rotate reversely to descend; the transmission mechanism comprises a second motor 314, the output end of the second motor 314 is fixed with a driving gear 310, correspondingly, a driven gear 311 is connected on the lead screw 308, the driving gear 310 can drive the driven gear 311 to rotate forward or reversely, thereby realizing the rotation of the lead screw 308 to rise or descend reversely.

[0055] When the lead screw 308 rotates forward to rise, the lifting platform 304 is pushed to rise, the volume of the liquid storage cavity 301 is reduced, and when the lead screw 308 reversely rotates to descend, the lifting platform 304 descends, and the volume of the liquid storage cavity 301 becomes larger; when the volume of the liquid storage cavity 301 is reduced, the liquid level of the liquid sample to be detected in the liquid storage cavity 301 rises, and when the liquid level rises to the liquid outlet 303, the liquid sample to be detected flows out from the liquid outlet 303.

[0056] As a preferred scheme of the transmission mechanism, please refer to Figure 3 , the transmission mechanism further comprises a first gear set 312 and a second gear set 313, the first gear set 312 comprises a first large gear and a first small gear, the first large gear and the first small gear are fixedly connected and coaxially arranged; the second gear set 313 comprises a second large gear and a second small gear, the second large gear and the second small gear are fixedly connected and coaxially arranged; the driven gear 311 is engaged with the first small gear, the first large gear is engaged with the second small gear, and the second large gear is engaged with the driving gear 310;

[0057] When the driving gear 310 rotates forward or reversely, the second large gear, the second small gear, the first large gear and the first small gear can be sequentially driven to rotate forward or reversely, thereby driving the driven gear 311 to rotate forward or reversely, and further driving the lead screw 308 to rotate forward to rise or reversely to descend.

[0058] The multi-stage gear transmission has the following purposes: through the combination of gears of different sizes, the change of rotation speed can be realized, the multi-stage gear transmission can provide more precise speed and position control, when the large gear and the small gear are engaged, the rotation speed of the output shaft can be changed, so that the lifting platform 304 can accurately control the speed during lifting; in addition, due to the limited space of the lower shell 102, the required motion transmission is realized through the multi-stage gear transmission, so that the space can be used more effectively, and through the multi-stage gear transmission, the load can be distributed to multiple gears, so that the load of a single gear can be reduced, the service life of the gear can be prolonged, and noise and vibration can be reduced by reducing direct contact; when the driven gear 311 needs to move in the opposite direction, the multi-stage gear transmission can more easily realize this.

[0059] As a preferred solution for detection, please refer to Figures 5 to 7 , the detection site is arranged in the lower shell 102, the detection site includes a test paper slot 111, the test paper slot 111 is fixed to the inner wall of the lower shell 102, for placing test paper; a liquid inlet 315 is formed on the test paper slot 111, and the two ends of the flow guide water absorption strip 316 are respectively fixed at the liquid inlet 315 and the liquid outlet 303; an installation site 117 is arranged beside the test paper slot 111, for installing a color sensor 112. The sensing end of the color sensor 112 faces the test paper slot 111, for sensing the detection line displayed on the test paper.

[0060] A specific structure is used to guide the reaction of the liquid sample and the test paper, that is, the liquid in the liquid storage cavity 301 is absorbed by the flow guide water absorption strip 316 through the liquid outlet 303, and is guided to the liquid inlet 315, and contacts the test paper in the test paper slot 111, and the index is detected by the colloidal gold test paper method. This method can control the accuracy of the reaction, and the flow guide water absorption strip 316 is used instead of a water pipe, which can effectively control the flow of the liquid sample.

[0061] As a preferred solution for the flow guide water absorption strip 316, the flow guide water absorption strip 316 is covered with a waterproof film 318, and the two ends of the waterproof film 318 are respectively fixedly connected with the liquid inlet 315 and the liquid outlet 303. The waterproof film 318 is used to avoid the situation that the liquid absorbed in the flow guide water absorption strip 316 is saturated, causing the flow guide water absorption strip 316 to fall off and causing detection failure, or the situation that the liquid gathers at the low point of the flow guide water absorption strip 316, causing the liquid to gather into droplets and fall from the flow guide water absorption strip 316 to other places in the cavity, damaging various electrical elements in the cavity.

[0062] Specifically, the flow guide water absorption strip 316 is made of a fiber material, and the fiber material is one of cotton, paper, and plastic.

[0064] During detection, the test paper detection adopts the colloidal gold method, the basic principle of which is to reduce gold ions into colloidal gold particles through chemical reduction method, the particles usually have a diameter of 10-100 nanometers and have a stable red appearance. During detection, the liquid sample is added to the test paper strip, and the sample moves along the test paper strip under capillary action. Usually, a test line (T line) and a control line (C line) are arranged on the test paper strip, and whether the detection target molecule is detected is determined by judging whether the T line and the C line appear. Then the first sensing end and the second sensing end correspond to the positions of the T line or the C line on the test paper respectively, so as to facilitate reading of the detection result, and after the control circuit board 104 judges the detection result, the on-off or color change of the indicator light 109 is controlled.

[0065] As a preferred scheme of the detection assembly 300, please refer to Figure 3 , the detection assembly 300 further comprises a stirring device 302; the stirring device 302 extends into the liquid storage cavity 301 and is used for stirring the liquid sample in the liquid storage cavity 301; the stirring device 302 comprises a first motor 306, and a propeller 305 is fixed to the output end of the first motor 306; the propeller 305 extends into the liquid storage cavity 301, and the first motor 306 can drive the output end to rotate, thereby driving the propeller 305 to rotate.

[0066] The stirring device 302 is suitable for detection of the liquid sample of the stool. Because the liquid sample of the stool is usually solid, the detection agent is first dripped into the liquid storage cavity 301, and when the stool block falls onto the area of the urine and stool channel 105 on the top of the upper shell, the detection agent in the liquid storage cavity contacts the stool block falling onto the urine and stool channel 105, or part of the stool block enters the liquid storage cavity 301 through the urine and stool channel 105 to contact the detection agent, forming a diluted liquid sample of the stool. After the liquid sample of the stool falls into the liquid storage cavity 301, the stirring device 302 is started to mix the detection agent and the liquid sample of the stool sufficiently. As the lifting platform 304 rises, the liquid sample to be detected in the liquid storage cavity 301 flows out from the liquid outlet 303. Because the flow guide and water absorbing strip 316 is used, only the liquid is enriched by the flow guide and water absorbing strip 316, and the solid liquid sample does not flow out.

[0067] As preferred, refer to Figure 1 and Figure 5 The upper shell 101 is internally provided with a control circuit board 104, and the top of the upper shell 101 is provided with temperature sensor mounting positions on both sides of the urine and stool passage 105 for mounting temperature sensors, and the temperature sensors are electrically connected with the control circuit board 104 in specific implementation; a strip-shaped hole 108 is formed in the upper shell 101, and an indicator lamp 109 is mounted in the strip-shaped hole 108, and the indicator lamp 109 is used for displaying detection results, and the indicator lamp 109 adopts a high-brightness LED lamp in specific implementation;

[0068] In specific implementation, the detection assembly 300 and the indicator lamp 109 are respectively electrically connected with the control circuit board 104; when urine or stool falls to the urine and stool passage 105, the temperature sensor senses the temperature and transmits a temperature sensor signal to the control circuit board 104, and the control circuit board 104 controls the detection circuit to be turned on, and then the detection assembly 300 starts detection work; the lower shell 102 is provided with a switch button 103, and the side of the switch button 103 facing the inside of the shell corresponds to a power switch on the control circuit board 104, and the switch button 103 extends from the side wall of the lower shell 102, so as to facilitate operation of an operator.

[0069] As preferred, refer to Figure 5 A through hole 110 is formed in the middle of the control circuit board 104, and the liquid storage cavity 301 extends from the bottom of the inside of the shell and passes through the through hole 110 and extends to the urine and stool passage 105.

[0070] As preferred, refer to Figure 4 The upper shell 101 is provided with a protective cover 106 on the top, and the protective cover 106 can cover the urine and stool passage 105 and is used for protecting the main body structure during transportation or storage.

[0075] Then, the liquid sample in the liquid storage cavity is tested, and the test result is waited, the bracket is lifted, the bracket and the whole portable urine and stool detection main body are discarded, and the urine and stool detection is completed.

[0076] The portable urine and stool detection main body has the following technical effects:

[0077] 1、 the portable urine and stool detection main body, the upper shell and the lower shell are sealed, liquid samples can only enter the liquid storage cavity through the urine and stool channel, the sealing ring can prevent the liquid samples of urine or stool from flowing into other areas in the cavity through the urine and stool channel, causing the circuit board to short circuit or the electromechanical equipment to be damaged, and the combination of the two can achieve sufficient waterproof function, ensuring that the portable urine and stool detection main body can normally perform detection work; the flow guide water absorption strip can use the diffusion effect of the material to adsorb and guide the liquid sample to the detection position, which can avoid a large amount of liquid sample from rapidly entering the detection position in a short time, which may cause structural impact on the test strip placed in the detection position or exceed the maximum liquid sample amount that the test strip can receive, causing detection failure or inaccurate detection results.

[0078] 2、 the portable urine and stool detection main body is designed to be disposable, which avoids cross contamination and ensures the detection accuracy of the product. Moreover, the portable urine and stool detection main body disclosed by the utility model has low cost and low price, and has higher cost performance and market competitiveness compared with similar products.
