DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0036] Embodiment one Reference Figures 1-13 The application discloses a sputum-dampness syndrome auxiliary detection system, which comprises a scraping assembly 1 for tongue fur, wherein the scraping assembly 1 comprises a scraping strip plate 4, the middle part of the scraping strip plate 4 is provided with a suction pipe 401, one end of the scraping strip plate 4 is provided with an extension part 5, the bottom of the extension part 5 is provided with a rotating assembly 2, and the lower part of the scraping strip plate 4 is provided with a collecting assembly 3.

[0037] As an embodiment of the collecting assembly 3, the collecting assembly 3 comprises a sealed box 301 and a double-way air pump 302, the double-way air pump 302 is a medical double-acting air pump, and the double-way air pump 302 is used for generating negative pressure in the sealed box 301; one end of the suction pipe 401 is fixedly connected with the sealed box 301.

[0038] The extension part 5 comprises an air cylinder 501, the extension end of the air cylinder 501 is provided with an extension rod 502, the bottom of the air cylinder 501 is fixedly connected with the rotating assembly 2 through a supporting block 503, and the extension rod 502 penetrates through the supporting block 503 and is fixedly connected with the scraping strip plate 4.

[0039] The rotating assembly 2 comprises a supporting plate 201 and a transmission belt 202, the supporting block 503 is fixedly connected with the transmission belt 202; one side of the supporting plate 201 is provided with a speed reducer motor 203, the rotating end of the speed reducer motor 203 can rotate in positive and reverse directions, the rotating end of the speed reducer motor 203 penetrates through the supporting plate 201 and is provided with a driving gear 2031; the inner side of the transmission belt 202 is provided with a limiting block 2021, the inner side of the supporting plate 201 is provided with an internal gear rack 2022, the internal gear rack 2022 is in meshing connection with the driving gear 2031, the inner side of the supporting plate 201 is provided with a limiting groove 2011, the outer side of the transmission belt 202 is provided with a limiting block 2021, and the limiting block 2021 is movably connected in the limiting groove 2011.

[0040] One end of the suction pipe 401 located outside the scraping strip plate 4 is a flexible pipe; one end of the scraping strip plate 4 away from the extension part 5 is provided as a scraping end, and the scraping end is provided with a flexible brush head.

[0041] In the application, the air cylinder 501 in the extension part 5 drives the scraping strip plate 4 and the suction pipe 401 in the scraping strip plate 4 to move forward and backward through the extension rod 502, so as to scrape off the tongue fur on the tongue of a patient. The sealed box 301 generates negative pressure through the double-way air pump 302, and the negative pressure in the sealed box 301 is used to suck the scraped-off tongue fur on the tongue to the sealed box 301 through one end of the suction pipe 401 away from the sealed box 301. The tongue fur sample is temporarily stored in the sealed box 301 and used for further biochemical analysis, for example, detecting the content of mucin, polysaccharide and inflammatory factors in the tongue fur sample - the tongue fur of a sputum-dampness syndrome patient is often rich in sticky substances, and the quantitative data of these components can provide objective indexes for the differentiation of sputum-dampness and assist in distinguishing normal tongue fur from pathological sputum-dampness tongue fur.

[0042] Further, since the amount of tongue coating on the tongue is small, the horizontal movement of the transmission belt 202 is driven by the reduction motor 203 in the rotating assembly 2 through the meshing of the drive gear 2031 and the internal gear rack 2022, and then the air cylinder 501, the scraping strip plate 4 and the suction pipe 401 are moved horizontally through the support block 503, which is used for comprehensive and uniform collection of tongue coating on the tongue surface. When the amount of tongue coating is small, the scraping strip plate 4 and the suction pipe 401 are moved horizontally, and the scraping strip plate 4 and the suction pipe 401 are moved horizontally by the air cylinder 501 to scrape the tongue coating, which expands the scraping range to obtain sufficient detection samples to meet the minimum sample requirement for subsequent component analysis.

[0043] In addition, the scraping strip plate 4 has a narrow width. When scraping the tongue coating, the horizontal position of the scraping strip plate 4 and the suction pipe 401 is driven by the reduction motor 203 and the air cylinder 501, which can accurately limit the operation to the middle and front part of the tongue surface. Even if the tongue coating near the tongue root is scraped, the contact area with the throat mucosa can be reduced, thereby reducing the irritation threshold and the discomfort of the patient such as vomiting and nausea. In addition, the narrow scraping strip plate 4 accurately targets the target area for scraping, which can also avoid interference with the normal area of the tongue coating, ensuring that the collected sample is more representative, such as sampling from thick and greasy parts to reduce dilution of normal tongue coating. The narrow scraping strip plate 4 can also better fit the curved surface of the tongue surface, thereby improving the uniformity of the scraping strip plate 4 on the tongue surface and avoiding the problem of local omission caused by uneven force due to the over-width of the scraping strip plate 4.

[0044] Further, after the tongue coating sampling is completed, the transmission belt 202 is a circulating transmission belt, and the air cylinder 501, the scraping strip plate 4 and the suction pipe 401 are moved by the reduction motor 203 through the meshing of the drive gear 2031 and the internal gear rack 2022. When the air cylinder 501 moves to the end of the support plate 201, the scraping strip plate 4 and the suction pipe 401 move out of the tongue surface and are located in the gap between the teeth and the cheeks in the oral vestibule, and the sputum sample is sucked; or the air cylinder 501 drives the scraping strip plate 4 and the suction pipe 401 to move horizontally through the extension rod 502, adjusts the position of the front end of the scraping strip plate 4 and the suction pipe 401, and moves the suction pipe 401 to the sputum-attached parts such as the tongue root or the throat entrance, and then the sputum is sucked through the suction pipe 401.

[0045] In addition, the scraping strip plate 4 is provided with a lighting lamp and a camera at the end away from the telescopic part 5, which is used for illuminating and observing the oral cavity, facilitating the adjustment of the front end position of the scraping strip plate 4 and the suction pipe 401 by the reduction motor 203 and the air cylinder 501, corresponding to the sputum absorption, and improving the accuracy of sputum collection.

[0046] Through the scraping and collection of the tongue coating sample and the absorption and collection of the sputum sample, the tongue coating sample and the sputum sample are collectively used as the detection sample, i.e. the tongue coating reflects the function of the spleen and stomach, and the sputum reflects the degree of sputum accumulation. The two samples are continuously collected.

[0047] By quantifying and standardizing the sampling of tongue coating and sputum samples, human errors are avoided, and a reliable foundation is provided for subsequent omics analysis after collection is completed. For example, by analyzing the texture of tongue coating and detecting the viscosity of sputum, through data cross-validation, white greasy coating + high-viscosity sputum → phlegm-dampness; yellow greasy coating + high-viscosity sputum → damp-heat.

[0048] In addition, as an objective quantitative tool system, in this detection system, urine parameters and pulse feature data can also be included in the machine learning algorithm, and through a feature vector-symptom type mapping model, the accuracy and intelligent level of phlegm-dampness syndrome differentiation are improved.

[0049] Embodiment Two This embodiment is a further improvement of the above-mentioned embodiment. The inside of the straw 401 is provided with a suction assembly 6. The suction assembly 6 includes a first squeezing head 601. One side of the first squeezing head 601 is provided with a bellows 603. The end of the bellows 603 away from the first squeezing head 601 is provided with a second squeezing head 602. The middle part of the first squeezing head 601 is provided with a cannula 604. The inside of the scraping strip plate 4 is provided with a baffle 405. The middle part of the baffle 405 is provided with a through hole 4051. The inside of the straw 401 is provided with a first electromagnet 402. The outside of the first squeezing head 601 is provided with an iron sheet. The iron sheet is used for magnetic attraction with the first electromagnet 402. In this embodiment, the suction assembly 6 is used as an independent sampling unit. When in use, the mounting block 4013 is separated from the scraping strip plate 4, so that the main pipe part 4011 is separated from the split part 4012. The suction assembly 6 is placed in the straw 401. Then the sealing block 4014 is used to reseal the split part 4012 and the main pipe part 4011 by corresponding to the sealing slot 4015. The two sides of the iron sheet on the first squeezing head 601 are provided with sealing rings. The first squeezing head 601 is in interference fit with the inner wall of the straw 401 through the sealing rings. After the suction assembly 6 is placed in the straw 401, high-pressure gas is input into the sealed box 301 through the bidirectional air pump 302. After the high-pressure gas enters the straw 401, the gas pushes the first squeezing head 601 and drives the bellows 603 and the second squeezing head 602 to move forward under the interference fit of the first squeezing head 601 and the straw 401. The gas in the bellows 603 is pushed out forward through the cannula 604. After the first squeezing head 601 contacts the baffle 405, the bellows 603 is in a compressed state, and the cannula 604 is inserted into the through hole 4051 correspondingly. At this time, the iron sheet on the first squeezing head 601 corresponds to the first electromagnet 402. By electrifying the first electromagnet 402, the first squeezing head 601 is sealed and locked in the inside of the straw 401. The diameter of the second squeezing head 602 is slightly smaller than that of the first squeezing head 601. The outer wall of the second squeezing head 602 does not contact the inner wall of the straw 401. After the front end of the scraping strip plate 4 completes scraping of the local tongue sample under the driving of the air cylinder 501, the gas in the sealed box 301 is discharged outward by the bidirectional air pump 302, so that the internal part of the sealed box 301 generates negative pressure, the corrugated tube 603 in the compressed state is expanded by the suction force of the insertion tube 604 when the corrugated tube 603 is expanded, the tongue scraped by the front end of the scraping strip plate 4 is sucked into the inside of the corrugated tube 603, and the tongue in the corrugated tube 603 naturally falls to the bottom of the corrugated tube 603. With repeated forward and reverse gas delivery of the bidirectional air pump 302, the pressure difference in the suction tube 401 is repeatedly generated, the corrugated tube 603 is repeatedly compressed and extended by the pressure difference, and the tongue scraped by the front end of the scraping strip plate 4 is sucked into the corrugated tube 603 during each extension of the corrugated tube 603.

[0050] As a further improvement of the above scheme, a second electromagnet 406 is arranged in the inside of the suction tube 401, the distance between the second electromagnet 406 and the first electromagnet 402 is half of the distance between the first pressing head 601 and the second pressing head 602 in the extended state of the corrugated tube 603; the second pressing head 602 is the same in structure as the first pressing head 601, that is, the outer side of the second pressing head 602 is provided with an iron sheet, and the sealing ring is arranged on both sides of the iron sheet on the second pressing head 602.

[0051] The inside of the sealed box 301 is provided with a negative pressure sensor for detecting the negative pressure value in the sealed box 301 and the suction tube 401.

[0052] In the use process, the bidirectional air pump 302 inputs high-pressure gas into the sealed box 301, the high-pressure gas pushes the first pressing head 601, the corrugated tube 603 and the second pressing head 602 to move forward after entering the suction tube 401, the second electromagnet 406 is energized and started after the first pressing head 601 contacts the baffle 405, the high-pressure gas continues to push the second pressing head 602 to extrude the gas in the corrugated tube 603 forward through the insertion tube 604, and when the corrugated tube 603 is pushed forward by the second pressing head 602 and moves forward to the second electromagnet 406, the second electromagnet 406 is magnetically adsorbed with the iron sheet of the second pressing head 602.

[0053] At this time, the gas in the sealed box 301 is discharged outward by the bidirectional air pump 302, so that a negative pressure is generated in the sealed box 301, and a negative pressure threshold is preset in the negative pressure sensor. When the negative pressure sensor detects that the negative pressure in the sealed box 301 reaches the preset negative pressure threshold, the second electromagnet 406 is powered on again after being powered off for a short time. During the short power-off period of the second electromagnet 406, the second squeezing head 602 is quickly moved away from the first squeezing head 601 by the attraction of the negative pressure in the straw 401 to the second squeezing head 602, and the corrugated pipe 603 in the half-compressed state is quickly extended and unfolded. The high negative pressure adsorption force generated in the corrugated pipe 603 at the moment enables the tongue sample to quickly pass through the cannula 604 into the corrugated pipe 603, and then the bidirectional air pump 302 inputs gas into the sealed box 301 to increase the pressure and push the second squeezing head 602 to move forward to the magnetic adsorption position of the second electromagnet 406. The bidirectional air pump 302 inputs and outputs gas into and out of the sealed box 301, and the on-off control of the second electromagnet 406 is matched, so that the corrugated pipe 603 repeatedly attracts and samples the tongue sample at the front end of the cannula 604.

[0054] Through the above improvement, the attraction pressure of the corrugated pipe 603 on the tongue sample can be ensured to be stable and strong each time, and the problem of uneven adsorption of the tongue sample caused by unstable attraction pressure is improved.

[0055] In addition, in order to determine that the first squeezing head 601 and the baffle 405 are in contact with each other, the scraping strip plate 4 and the front end of the straw 401 can be made of transparent material, so that the position of the suction assembly 6 can be directly observed.

[0056] Further, the gas pipe 403 is arranged on the straw 401, one end of the gas pipe 403 away from the straw 401 penetrates through the scraping strip plate 4 and is located outside the scraping strip plate 4, and the electromagnetic valve is arranged on the gas pipe 403 and is used to control the communication state between the gas pipe 403 and the outside.

[0057] Meanwhile, the blocking piece 404 is arranged on one side of the baffle 405, and the blocking piece 404 is used to form a closed state for the straw 401.

[0058] As an embodiment of the blocking piece 404, the blocking piece 404 comprises a rotating groove 4041, a fixed column 4043 is arranged in the middle of the rotating groove 4041, the fixed column 4043 is connected with a rotating ring 4044 through a torsional spring 4045, and the rotating ring 4044 is rotationally connected in the inside of the rotating groove 4041. The inside of the rotating ring 4044 is provided with a sealing disc 4042, and the outside of the sealing disc 4042 is provided with a sealing gasket 40421.

[0059] In the initial state, the two sealing discs 4042 are kept coincident on both sides under the elastic support of the torsion spring 4045 to the rotating ring 4044, and the rotating groove 4041 is provided with a movable gap in the direction close to the baffle 405, for the rotating disc 4042 to rotate in the direction close to the baffle 405. When the suction assembly 6 moves forward, the first extrusion head 601 is pushed close to the baffle 405 by the pressure in the suction pipe 401, and is blocked by the rotating ring 4044 to be positioned on one side of the rotating ring 4044. At this time, the cannula 604 pushes the two sealing discs 4042 to rotate in the direction close to the baffle 405 with the fixed column 4043 as the center, and the cannula 604 is inserted into the through hole 4051.

[0060] When the collection of the sample of the tongue coating is completed by the suction assembly 6, the first electromagnet 402 and the second electromagnet 406 are powered off. At this time, the gas in the sealed box 301 is discharged outward by the bidirectional air pump 302, and the suction assembly 6 is collected by moving into the sealed box 301 by using the negative pressure of the sealed box 301 and the suction pipe 401. In this process, the valve on the air pipe 403 is opened, and the two sealing discs 4042 are kept coincident on both sides under the elastic support of the torsion spring 4045 to the rotating ring 4044, and the rotating groove 4041 is provided with a movable gap in the direction close to the baffle 405, for the rotating disc 4042 to rotate in the direction close to the baffle 405. When the suction assembly 6 moves forward, the first extrusion head 601 is pushed close to the baffle 405 by the pressure in the suction pipe 401, and is blocked by the rotating ring 4044 to be positioned on one side of the rotating ring 4044. At this time, the cannula 604 pushes the two sealing discs 4042 to rotate in the direction close to the baffle 405 with the fixed column 4043 as the center, and the cannula 604 is inserted into the through hole 4051.

[0061] According to the needs of use, not less than two suction assemblies 6 are used to collect the sample of the tongue coating and the sample of the sputum each time. When the collection of the sample is completed, the gas in the sealed box 301 is discharged outward by the bidirectional air pump 302, so that the suction assembly 6 enters the sealed box 301. When the negative pressure sensor in the sealed box 301 suddenly decreases, it indicates that the suction assembly 6 enters the sealed box 301. The sealed box 301 can be provided with a closed door, and the suction assembly 6 containing the sample can be taken out by opening the closed door for further biochemical analysis.

In the initial state, the closing plate 702 forms a closure to the first opening 3011.

[0063] The sealing box 301 is provided with a shunt part 8, which comprises a shunt shell 801 and a second electric push rod 802. The telescopic end of the second electric push rod 802 is provided with a clamping plate 803, and one end of the clamping plate 803 inside the sealing box 301 is provided with an inclined surface. The middle part of the shunt shell 801 is provided with a partition plate 804, which divides the shunt shell 801 into two temporary storage cavities 805 for temporarily storing the suction assembly 6.

[0064] Second openings 3012 corresponding to the clamping plate 803 are formed on the front and back sides of the sealing box 301. In the initial state, the clamping plate 803 closes the second openings 3012.

[0065] In use, the suction assembly 6 entering the sealing box 301 falls above the closure plate 702. According to different types of samples collected, such as tongue coating samples and sputum samples, two different samples are stored in the two temporary storage cavities 805. Specifically, the first electric push rod 701 drives the closure plate 702 to move out of the sealing box 301, the suction assembly 6 on the closure plate 702 falls between the two clamping plates 803 and directly above the partition plate 804, and the suction assembly 6 is stored according to the preset storage position. For example, for tongue coating samples, the second electric push rod 802 on the front side drives the clamping plate 803 to move away from the sealing box 301, and the suction assembly 6 containing the tongue coating sample falls into the temporary storage cavity 805 on the front side under the influence of natural gravity. For sputum samples, the second electric push rod 802 on the back side drives the clamping plate 803 to move away from the sealing box 301, and the suction assembly 6 containing the sputum sample falls into the temporary storage cavity 805 on the back side. In this way, different samples are stored separately to meet the different storage needs of different samples and reduce cross-contamination between different samples.

[0066] Further, a third electric push rod 806 is arranged at a position corresponding to the temporary storage cavity 805 of the shunt shell 801. The telescopic end of the third electric push rod 806 penetrates one side of the shunt shell 801 and is provided with a push block 8061. The end of the shunt shell 801 away from the third electric push rod 806 is provided with a connecting head 807.

[0067] In the initial state, the connecting head 807 is in a closed state. When the suction assembly 6 is to be taken out, the telescopic end of the third electric push rod 806 extends and pushes the suction assembly 6 out of the connecting head 807 through the push block 8061. The two connecting heads 807 correspond to two different types of samples respectively. A protective bag can be pre-installed on the connecting head 807 to allow the suction assembly 6 to directly fall into the protective bag.
