DETAILED DESCRIPTION

[0033] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0034] The specific embodiment of the present invention provides a fully automatic urine sampling, detection and flushing system, as shown in the attached Figure 1 As shown, it includes a sampling mechanism 1, a flushing mechanism 2, an exhaust mechanism 3, a detection device 4, a discharge mechanism 5, a control panel 6 and necessary connecting pipelines, etc., wherein the sampling mechanism 1 is used for collecting urine samples, and the sampling mechanism needs to be connected to a urine collector. The sampling mechanism 1 includes a first pipeline 101, a first solenoid valve 102, a peristaltic pump 103, a motor-driven double-headed syringe 104 and a drip needle 105 connected in sequence, wherein the first pipeline 101 is used to achieve connection with the urine collector. The urine collectors currently used include toilets, squat toilets and urinals, etc. In order to achieve automation, it is also necessary to set a first liquid sensor 7 at one end of the first pipeline 101 close to the urine collector, and the first liquid sensor 7 is provided at the first end of the first pipeline 101 close to the urine collector. A liquid sensor 7 is connected to the control board 6. When the first liquid sensor 7 detects urine, it feeds back to the control board 6. The control board 6 starts the system to collect urine. One end of the first pipe 101 is connected to the urine collector, and the other end of the first pipe 101 is connected to the first solenoid valve 102. The first solenoid valve 102 controls the on-off of the first pipe 101 to prepare for the subsequent exhaust. The inlet of the peristaltic pump 103 is connected to the first solenoid valve 102, and the outlet is connected to the motor-driven double-headed syringe 104. The two ends of the motor-driven double-headed syringe 104 are respectively connected to the peristaltic pump 103 and the dripping needle 105, the first end is connected to the peristaltic pump 103, and the second end is connected to the dripping needle 105.

[0035] In order to make the system reusable and prevent the patient's urine sample from being mixed, a flushing mechanism 2 is also required to flush the necessary components in the system. The specific flushing mechanism 2 includes a second pipe 201, a second solenoid valve 202 and a third solenoid valve 203. The flushing mechanism 2 is connected to the external tap water pipe, and then controls the flow of tap water through the solenoid valve, thereby playing the role of flushing different pipes and components. One end of the second pipe 201 is connected to the external water pipe and the other end is connected to the second solenoid valve 202 and the third solenoid valve 203. The second solenoid valve 202 and the third solenoid valve 203 are respectively connected to different pipes, wherein the second solenoid valve 202 is connected to the first pipe 101, and the external tap water can enter the first pipe 101 through the second solenoid valve 202 to flush the first pipe 101. The third solenoid valve 203 is connected to the connecting pipe between the second head and the drip needle 105; it can flush the drip needle 105, the motor-driven double-headed syringe 104 and the peristaltic pump 103.

[0036] Since there is a problem of extracting air when extracting urine samples, it is necessary to exhaust the air before dropping the sample. The exhaust mechanism 3 provided in the present application includes a fourth solenoid valve and a pipeline. The fourth solenoid valve is connected to the liquid inlet end of the peristaltic pump 103 through the pipeline. It is also necessary to drive the double-headed syringe 104 with a motor to move up the double-headed end so that after the urine sample enters the motor-driven double-headed syringe 104, the liquid is located at the bottom due to its own weight. Pushing the push rod of the motor-driven double-headed syringe 104 can achieve the function of exhausting the air. The fourth solenoid valve is only in the open state when exhausting. When exhausting, all other solenoid valves are closed, and only the fourth solenoid valve is opened. When the push rod of the motor-driven double-headed syringe 104 is pushed, the air in the motor-driven double-headed syringe 104 will pass through the peristaltic pump 103 and then be discharged through the fourth solenoid valve.

[0037] After the liquid discharge is completed, the sample drop detection stage is entered. The detection device 4 includes a linear drive mechanism 401, a test paper push box 402 and an image collector 403. The drop needle 105 is arranged on the linear drive mechanism 401. The linear drive mechanism 401 can drive the drop needle 105 to move from the liquid discharge mechanism 5 to the test paper push box 402 to drop the sample. After the sample is dropped, it will return to its original position under the action of the linear drive mechanism 401. The test paper push box 402 is arranged below the drop needle 105 and is located on one side of the liquid discharge mechanism 5. The linear drive mechanism 401 is used to drive the drop needle 105 to move between the funnel 501 and the test paper push box 402. The image collector 403 is arranged on the linear drive mechanism 401. The image collector 403 is used to collect the image of the test paper after the urine sample is dropped and feed it back to the control board 6. The image collector 403 is connected to the control board 6; the image collector 403 can be a camera, which can clearly collect the image of the test paper after the sample is dropped. The control board 6 records the colors of each image in advance, compares the collected image with the pre-recorded image, and obtains the structure of the patient's urine sample through the display terminal or sends a signal to the patient's mobile terminal.

[0038] After the dripping of urine is completed, the excess urine sample needs to be discharged through the drainage mechanism 5, which includes a funnel 501 and a third pipe 502. The funnel 501 is located below the dripping needle 105, and one end of the third pipe 502 is connected to the funnel 501 and the other end is connected to the drainage pipe; the drainage pipe connected to the third pipe 502 can be directly connected to the urine collector for discharge, or connected to the sewer. After the drainage is completed, the system is flushed through the flushing mechanism 2.

[0039] It is worth mentioning that in order to realize the automation of the system, the control board 6 needs to be connected with the motor-driven double-head syringe 104, the first solenoid valve 102, the second solenoid valve 202, the third solenoid valve 203, the fourth solenoid valve and the linear drive mechanism 401, and each mechanism is pre-set to meet the conditions of the action of each component, so as to finally realize the complete automation of sampling, detection and flushing.

[0040] It is also necessary to set a second liquid sensor 8 to realize the action of dripping the sample after the gas is emptied. The second liquid sensor 8 is set on the connecting pipeline between the motor-driven double-headed syringe 104 and the dripping needle 105. When the motor-driven double-headed syringe 104 is emptied, the upper air in the motor-driven double-headed syringe 104 will be discharged from the dripping needle 105 and the peristaltic pump 103. After the air is discharged, the urine sample will continue to be discharged from the dripping needle 105 and the peristaltic pump 103. After the urine sample enters the dripping needle 105, it will be sensed by the second liquid sensor 8, and then the second liquid sensor 8 will be fed back to the control board 6, and the control board 6 receives it. After the lower signal, a control signal is sent to the fourth solenoid valve to close and stop exhausting the gas. At the same time, the control board 6 will also send a control signal to the linear drive mechanism 401 to drive the drip needle 105 to move toward the detection device 4. At the same time, the motor drives the double-headed syringe 104 to continuously discharge the urine sample, and the urine sample is dripped onto the test paper on the detection device 4 to complete the dripping. After the dripping is completed, the image collector 403 on the linear drive mechanism 401 sends the collected image of the dripping test paper to the control board 6. The control board 6 obtains the patient's urine sample structure based on the pre-recorded image and the collected image and finally sends it to the terminal (mobile phone, etc.) used by the patient.

[0041] Specifically, the fourth solenoid valve is connected to the connecting pipeline between the fourth solenoid valve and the peristaltic pump 103 through the first three-way valve 9. The motor-driven double-headed syringe 104 is vertically arranged with the double-headed end as the upper end. When the other solenoid valves are closed and the fourth solenoid valve is opened, it can be used to exhaust the air in the motor-driven double-headed syringe 104.

[0042] The motor-driven double-headed syringe 104 provided in the specific embodiment of the present application includes a double-headed syringe 1041, a first screw nut pair 1042 and a first motor 1043. The double-headed syringe 1041 is used for extracting and pushing out urine samples. The specific action is completed by the first motor 1043 driving the first screw nut pair 1042. The double-headed syringe 1041 is connected to the first screw nut pair 1042, and the first screw nut pair 1042 is connected to the push rod 14 of the double-headed syringe 1041. The first screw nut pair 104 2 is connected to the first motor 1043, the motor can drive the nut of the first screw nut pair 1042 to move linearly, and the push rod 14 connected to the nut will move with the movement of the nut, thereby completing the pushing and pulling actions. The first motor 1043 is connected to the control board 6. After the first liquid sensor 7 senses the urine sample, it will send a signal to the control board 6. The control board 6 receives the signal and then sends a control signal to the first motor 1043, so that it works to drive the first screw nut pair 1042 to move, thereby completing the work of extracting the urine sample.

[0043] The double-headed syringe 1041 is vertically arranged and includes a double-headed screw cap 10, a syringe 11, a plunger 12, a bottom screw cap 13 and a push rod 14. The double-headed screw cap 10 is a cover body with two parallel outlets. The two heads are respectively connected to the peristaltic pump 103 and the drip needle 105. The double-headed screw cap 10 is arranged at the top of the syringe 11. The double-headed syringe 1041 is arranged in a vertical opening upward. An internal thread can be arranged in the double-headed screw cap 10, and an external thread can be arranged on the outer wall of the syringe 11, and they are connected by threads. The bottom screw cap 13 is arranged at the lower end of the syringe 11, and a threaded connection can also be adopted similar to the above. The push rod 14 is slidably connected to the bottom screw cap 13. A through hole is arranged in the center of the bottom screw cap 13, and the push rod 14 is penetrated in the through hole and slidably connected thereto. The plunger 12 is arranged inside the injection barrel 11 , one end of the push rod 14 extends into the injection barrel 11 and is connected to the plunger 12 , and the other end is located outside the injection barrel 11 . The end of the push rod 14 located outside the injection barrel 11 is connected to the nut of the first screw nut pair 1042 .

[0044] The double-headed syringe 1041 can also be provided with two heads separately to ensure that other components remain unchanged, and then the double-headed screw cap 10 is changed into a single-headed screw cap, and the single-headed screw cap is arranged at the bottom of the syringe 11, wherein the first head is arranged at the bottom end of the double-headed syringe 1041, the second head is arranged on the side wall of the syringe 11, and the bottom screw cap 13 is arranged at the top of the syringe 11. At this time, the double-headed syringe 1041 is arranged vertically downward, and then the first head is connected to the peristaltic pump 103, and the second head is connected to the drip needle 105. The setting position of the second head and the side wall of the syringe 11 can be adjusted later to ensure that the internal air of the double-headed syringe 1041 can be effectively discharged.

[0045] The linear drive mechanism 401 can adopt a structural form of a second motor 4011, a second screw nut pair 4012 and a needle mounting bracket 4013. Specifically, the second motor 4011 is connected to the second screw nut pair 4012 to provide power for the second screw nut pair 4012, and the second motor 4011 is connected to the screw of the second screw nut pair 4012. The needle mounting bracket 4013 is arranged on the second screw nut pair 4012, specifically, on the nut connected to the second screw nut pair 4012, and can move with the movement of the nut. The drip needle 105 is arranged on the needle mounting bracket 4013, and the second motor 4011 drives the second screw nut pair 4012 to move and indirectly drives the drip needle 105 to move.

[0046] The image collector 403 and the needle mounting bracket 4013 are both arranged on the nut of the second screw nut pair 4012. The image collector 403 and the needle mounting bracket 4013 move simultaneously with the movement of the nut. The image collector 403 is arranged on the side of the needle mounting bracket 4013 away from the double-headed syringe 1041. At this time, when the dripping needle 105 completes dripping and moves back, it will pass above the dripping test paper away from the double-headed syringe 1041, thereby completing the image acquisition of the dripping test paper.

[0047] In order to achieve the connection between the pipeline and each solenoid valve, it is necessary to use multiple three-way connectors to meet the connection of different positions, such as the attached Figure 1 As shown, the second solenoid valve 202 is connected to the first pipeline 101 through the second three-way connection 15; the second pipeline 201 needs to be connected to the second solenoid valve 202 and the third solenoid valve 203, so they can be connected separately through the third three-way connection 16. The third solenoid valve 203 is connected to the connecting pipeline between the second head and the drip needle 105, and a fourth three-way connection 17 needs to be provided on the connecting pipeline, and the third connector of the fourth three-way connection 17 can be connected to the third solenoid valve 203.

[0048] The following introduces the working mode of the fully automatic urine sampling, testing and flushing system by explaining the actions of each solenoid valve and motor during different actions.

[0049] First, the first liquid sensor 7 collects urine sample information in the urine collector and sends it to the control board 6. At this time, the control board starts the sampling working mode:

[0050] The first solenoid valve 102 is opened, and the other solenoid valves are closed. At the same time, the first motor 1043 starts to rotate forward, pulling the push rod 14 to move, so that the double-headed syringe 1041 completes the extraction action. At this time, the urine sample enters from the first pipeline 101 through the second three-way valve 15, the first solenoid valve 102, and the first three-way valve 9 and then enters the peristaltic pump 103, and then is discharged from the peristaltic pump 103 into the double-headed syringe 1041 to complete the sampling.

[0051] After sampling is completed, the control board 6 performs the emptying work:

[0052] At this time, the fourth solenoid valve opens, and then the remaining solenoid valves are closed, the first motor 1043 reverses, pushing the push rod 14 to move, compressing the space inside the double-headed syringe 1041, and the air located in the upper part of the double-headed syringe 1041 is discharged from the double-head position and enters the drip needle 105 and the peristaltic pump 103 respectively. The air entering the peristaltic pump 103 is discharged from the fourth solenoid valve. When the air in the double-headed syringe 1041 is discharged, the urine sample will enter the drip needle 105 and the peristaltic pump 103. The urine sample enters the drip needle 105 and is detected by the second liquid sensor 8 arranged therein, and then fed back to the control board 6.

[0053] The control panel 6 performs the next step of urine sample testing:

[0054] At this time, all four solenoid valves are in a closed state, and while the first motor 1043 is reversed, the second motor 4011 also moves. The second motor 4011 drives the dripping needle 105 to move to the detection device 4 to drip samples. The urine sample is pushed out by the push rod 14 pushed by the first motor 1043 and drips onto the test paper. When the dripping is completed, the second motor 4011 reverses and drives the dripping needle 105 to return. During the return process, the image collector 403 located on the second screw nut pair 4012 collects the image of the test paper after the sample is dripped and sends it to the control board 6. After the control board 6 compares and obtains the result, it sends the information to the user terminal (mobile phone, etc.). At the same time, the push rod 14 is pushed to the top to discharge the internal urine sample, and then the fourth solenoid valve is opened. At this time, the peristaltic pump 103 rotates forward to draw external gas from the fourth solenoid valve, and finally discharges the urine sample through the first three-way 9, the peristaltic pump 103, the double-headed syringe 1041 and the dripping needle 105 in sequence.

[0055] Control panel 6 performs flushing action:

[0056] During flushing, the first solenoid valve 102, the second solenoid valve 202 and the third solenoid valve 203 are all opened, and then the fourth solenoid valve is closed, the second motor 4011 returns to its position and stops moving, the first motor 1043 returns to its position and stops moving, and the outside water enters through the second pipe 201, and part of the outside water passes through the third three-way 16 and then passes through the second solenoid valve 202 and the first pipe to achieve flushing of the sampling tube part; part of the outside water passes through the third three-way 16 and then passes through the third solenoid valve 203, the fourth three-way 17, the double-headed syringe 1041, the peristaltic pump 103, the first three-way 9, and the first solenoid valve 102, and is finally discharged from the first pipe 101 to flush the double-headed syringe. At the same time, the first motor 1043 drives the push rod to move up and down to empty the liquid in the double-headed syringe 1041; and part of the liquid passes through the third three-way 16, the third solenoid valve 203, the fourth three-way 17 and then the drip needle 105 to flush the drip needle part.

[0057] Finally, empty the machine:

[0058] After the flushing process is completed, another exhaust process is performed. At this time, the four solenoid valves are closed, and the first motor 1043 rotates, pushing the push rod 14 to move, so that the liquid in the double-headed syringe 1041 is discharged, and part of the gas is discharged from the needle. Then the control board 6 controls the peristaltic pump 103 to operate, so that it runs forward for a short time. This time is checked according to the flow rate and power consumption of the pump, and then the fourth solenoid valve is opened to let air enter. The peristaltic pump 103 continues to run, thereby removing excess liquid in the double-headed syringe 1041 and achieving no excessive residual liquid residue during the next sampling process.

[0059] Eventually, all parts return to their original state, ready for the next urine sampling, testing, and flushing.

[0060] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
