Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary equipment technology, specifically relating to an integrated device for collecting and analyzing sputum in internal medicine. Background Technology

[0002] In the field of clinical medicine, sputum, as an important secretion of the human respiratory tract, has its composition, properties, color, and viscosity closely related to the diagnosis, treatment efficacy evaluation, and prognosis of respiratory diseases. Especially in internal medicine clinical diagnosis and treatment, sputum testing is an indispensable auxiliary diagnostic tool for common respiratory diseases such as pneumonia, chronic obstructive pulmonary disease, tuberculosis, and bronchiectasis. By analyzing pathogens, inflammatory factors, and cellular components in sputum, key evidence can be provided for clinicians to formulate precise treatment plans.

[0003] Existing equipment often separates functions such as sputum suction, testing, disinfection, and waste disposal into different devices. Medical staff need to manually transfer sputum from the suction device to the analyzer and manually pour out the waste after testing. This process is not only cumbersome and time-consuming, increasing the workload of medical staff, but also prone to sputum leakage and aerosol diffusion, causing cross-contamination. Moreover, most existing equipment can only process one sputum sample at a time, and cannot achieve orderly flow and stable residence of the testing container at the suction, analysis, disinfection, and drainage stations, resulting in low sample processing efficiency and difficulty in meeting the testing needs of multiple patients and high frequency in internal medicine. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an integrated device for sputum collection and analysis in internal medicine.

[0005] The technical solution adopted to solve the above technical problems is: an integrated device for collecting and analyzing sputum in internal medicine, including a mobile cabinet. The top of the mobile cabinet is equipped with a display screen and a sputum suction interface. The inside of the mobile cabinet is equipped with two storage compartments. One storage compartment contains multiple disposable suction tubes, and the other storage compartment contains multiple waste tubes. The mobile cabinet is rotatably connected to a turntable inside. The mobile cabinet is equipped with an intermittent rotation mechanism for rotating the turntable. Multiple detection tanks are installed on the top of the turntable. Gravity sensors corresponding to the detection tanks are installed inside the turntable. A negative pressure suction mechanism for performing negative pressure suction on the detection tanks is installed on the top of the turntable. A waste liquid discharge mechanism for draining liquid is installed inside the mobile cabinet. An electronic telescopic rod assembly is installed on the inner wall of the mobile cabinet near the top. A bottle mouth sealing block is fixedly connected to the output end of the electronic telescopic rod assembly. An analysis and processing mechanism for analyzing sputum is provided on the top of the bottle mouth sealing block. Multiple storage tanks are fixedly connected inside the mobile cabinet.

[0006] Furthermore, the intermittent rotation mechanism includes a rotating motor installed inside the mobile cabinet, an incomplete gear plate fixedly connected to the output end of the rotating motor, and an incomplete gear ring that mates with the incomplete gear plate fixedly connected to the bottom of the turntable.

[0007] With the above technical solution, when the rotating motor starts, its output end will drive the incomplete gear plate to rotate synchronously. Since the incomplete gear plate only has teeth in a local area, the power of the rotating motor will only be transmitted to the incomplete gear ring when the toothed area of ​​the gear plate meshes with the toothed area of ​​the incomplete gear ring at the bottom of the turntable, thereby driving the turntable to rotate together. When the incomplete gear plate rotates to the smooth area without teeth, its meshing relationship with the incomplete gear ring is broken, the turntable loses power input and remains stationary. During the continuous operation of the rotating motor, the incomplete gear plate and the incomplete gear ring will periodically complete the cycle of "meshing transmission - disengagement and stop", ultimately realizing the intermittent rotation of the turntable so that the detection tank on the turntable can complete the corresponding operation process during the stationary phase.

[0008] Furthermore, the disk diameter of the incomplete gear plate is smaller than the annular inner diameter of the incomplete gear ring, and the incomplete gear plate is embedded in the annular space of the incomplete gear ring.

[0009] Through the above technical solution, the incomplete gear plate is embedded in the annular space of the incomplete gear ring, which makes the structure of the entire intermittent rotation mechanism more compact, reduces the volume it occupies inside the device, and adapts to the limited installation space of the mobile cabinet.

[0010] Furthermore, the negative pressure suction mechanism includes multiple tracheas installed on the outer wall of the detection tank. Each of the multiple tracheas is equipped with a gas one-way valve and a solenoid valve on its outer wall. A gas distributor is installed at the other end of each of the multiple tracheas. A negative pressure buffer tank is fixedly connected to the bottom of the gas distributor. A negative pressure pipe is installed on the outer wall of the negative pressure buffer tank near the bottom. An adjustable speed oil-free vacuum pump is installed at the other end of the negative pressure pipe. A high-efficiency filter is installed on one side of the adjustable speed oil-free vacuum pump.

[0011] The above technical solution involves activating an adjustable-speed oil-free vacuum pump, which evacuates the negative pressure buffer tank through a negative pressure tube, creating a stable negative pressure environment inside the buffer tank. When a test tank requires suctioning, the solenoid valve on the outer wall of the corresponding trachea opens simultaneously. The gas distributor transmits the negative pressure from the negative pressure buffer tank to the test tank through the trachea. At the same time, the gas one-way valve on the trachea prevents sputum or gas in the test tank from flowing back into the gas path. Under this negative pressure, sputum is drawn into the corresponding test tank for collection. During the process, the adjustable-speed oil-free vacuum pump can adjust the speed to change the negative pressure intensity, adapting to different suctioning scenarios. The gas discharged by the adjustable-speed oil-free vacuum pump must be filtered through a high-efficiency filter to prevent sputum aerosols from spreading and causing pollution.

[0012] Furthermore, the negative pressure buffer tank is embedded in the internal groove of the turntable, and the top of the negative pressure buffer tank is connected to the bottom of the gas distributor by a flange seal.

[0013] The above technical solution embeds the negative pressure buffer canister into the internal groove of the turntable, which makes full use of the idle space inside the turntable and avoids the buffer canister occupying additional device volume. This allows the negative pressure suction mechanism and the turntable to form a compact integrated layout, reducing space waste caused by the scattered installation of components. At the same time, the buffer canister rotates intermittently and synchronously with the turntable, which can prevent the trachea from being pulled or twisted due to the rotation of the turntable, reduce the wear and leakage risk of the airway connection parts, and ensure the stability of negative pressure transmission.

[0014] Furthermore, the waste liquid discharge mechanism includes multiple check valves installed at the bottom of the detection tank. Each of the multiple check valves is fixedly connected to a waste liquid pipe at its bottom. A manifold is installed at the other end of each of the multiple waste liquid pipes. A rotary sealing joint rotating end is installed at the bottom of the manifold. A rotary sealing joint fixing end is provided on the outer wall of the rotary sealing joint rotating end. A waste liquid tank is fixedly connected to the bottom of the rotary sealing joint fixing end. A drain pipe is fixedly connected to the bottom of the waste liquid tank.

[0015] With the above technical solution, after the sputum in the testing tank is collected, analyzed, and rinsed, the check valve at the bottom of the testing tank is opened. Under the assistance of gravity and residual negative pressure, the waste liquid in the tank is collected into the manifold through the independent waste liquid pipes. Since the manifold rotates intermittently and synchronously with the turntable, the rotating end of the rotary sealing joint connected to its bottom will form a dynamic sealing fit with the fixed end of the fixed rotary sealing joint. This ensures that the waste liquid channel is not interrupted when the turntable rotates and prevents waste liquid leakage. Subsequently, the waste liquid flows into the waste liquid tank below through the fixed end of the rotary sealing joint for centralized storage. When the waste liquid in the waste liquid tank reaches the preset capacity, the waste liquid can be discharged and treated by opening the drain pipe at the bottom, realizing the orderly collection and compliant discharge of waste liquid.

[0016] Furthermore, the analysis and processing mechanism includes a protective cover installed on top of the bottle neck sealing block. Inside the protective cover are a micro peristaltic pump, a signal processing module, a small metering pump, and a high-pressure pump. A flushing pipe is fixedly connected to the bottom of the high-pressure pump, and a flow divider ring is fixedly connected to the other end of the flushing pipe. Multiple evenly distributed flushing nozzles are installed at the bottom of the flow divider ring. A sealing head is installed near the center of the top of the bottle neck sealing block. Two connecting pipes are fixedly connected to the top of the sealing head, and these two connecting pipes are respectively connected to the micro peristaltic pump and the small metering pump. A stirring motor is installed inside the bottle neck sealing block, and a drive gear is fixedly connected to the output end of the stirring motor. A rotatable connection is made to the top of the bottle neck sealing block and the drive gear. A meshing transmission gear ring has a hollow tube fixedly connected to its bottom. Polytetrafluoroethylene-coated nylon bristles are installed on the outer wall of the hollow tube near its bottom. Multiple drainage holes are opened on the outer wall of the hollow tube near its bottom. Two external bearings are installed between the hollow tube and the bottle mouth sealing block. A release tube is installed inside the hollow tube. Two internal bearings are installed between the hollow tube and the release tube. The bottoms of two connecting tubes are sleeved inside the release tube. A protective tube is installed inside the release tube. Two data cable bundle tubes are installed inside the protective tube. One end of each data cable bundle tube is connected to an RGB color sensor and a viscosity sensor, respectively. The other end of each data cable bundle tube is connected to a signal processing module.

[0017] With the above technical solution, after the testing tank intermittently rotates to the analysis station and is sealed by the sealing head on top of the bottle mouth sealing block, the small metering pump inside the protective cover is first started. A fixed amount of diluent from the storage tank is then delivered to the release tube through the corresponding connecting pipe, and then evenly injected into the sputum in the testing tank through multiple drainage holes on the outer wall of the hollow tube. Subsequently, the stirring motor inside the bottle mouth sealing block starts, and its output drive gear drives the meshing transmission gear ring to rotate, thereby driving the hollow tube, which is fixedly connected to the transmission gear ring, to rotate synchronously. The hollow tube maintains a stable rotational engagement with the bottle mouth sealing block through an external bearing, and forms a relative rotation with the stationary release tube through an internal bearing, preventing pipe entanglement. The polytetrafluoroethylene-coated nylon bristles on the outer wall of the hollow tube rotate with the tube body. The system ensures thorough mixing of sputum and diluent, completing the sputum dilution pretreatment. After dilution, two data cable bundles inside the protective tube of the release tube are connected to an RGB color sensor and a viscosity sensor, respectively. The collected sputum dilution color and viscosity data are transmitted in real time to the signal processing module for analysis and detection, generating test results. After detection, a micro peristaltic pump is activated to deliver the disinfectant from the storage tank to the test tank through another connecting tube for disinfection. At the same time, a high-pressure pump delivers the rinsing solution to the diversion ring through the rinsing pipe. Multiple evenly distributed rinsing nozzles at the bottom of the ring spray the solution onto the inner wall of the test tank and the bristles of the hollow tube. With the continuous rotation of the bristles, efficient rinsing and disinfection of the test tank are achieved, ensuring sealing performance throughout the process and preventing waste liquid leakage or aerosol diffusion.

[0018] Furthermore, the diversion ring is an annular hollow cavity structure, and the multiple flushing nozzles at its bottom are angled downwards at 45° toward the inner wall of the detection tank.

[0019] Through the above technical solution, the diversion ring of the annular hollow cavity can evenly distribute the rinsing liquid to each rinsing nozzle, and the downward 45° spray angle can accurately cover the entire inner wall of the test tank, achieving rinsing without dead angles, effectively avoiding sputum residue and bacterial growth, and ensuring the cleaning and disinfection effect.

[0020] Furthermore, the outer wall of the hollow tube and the inner wall of the testing tank are both coated with a medical-grade ceramic coating, and the polytetrafluoroethylene coated nylon bristles are arranged in a spiral pattern. A diaphragm-type one-way valve is installed inside each of the multiple drainage holes.

[0021] Through the above technical solutions, the medical-grade ceramic coating possesses excellent biocompatibility, wear resistance, and low surface energy, which can significantly reduce the risk of sputum and reagents adhering to the outer wall of the hollow tube and the inner wall of the testing vessel, reducing residual contamination. At the same time, it can withstand long-term friction of the bristles without being easily damaged, and can be quickly cleaned by rinsing liquid. The spiral sparse arrangement of the PTFE-coated nylon bristles can generate spiral shear force during stirring, improving the uniformity of mixing of sputum and diluent, while avoiding the accumulation of liquid residue caused by dense arrangement. Combined with the non-stick properties of the coating, it further reduces the probability of contaminant adhesion. The diaphragm-type one-way valve in the drain hole can accurately control the one-way release of diluent and disinfectant, effectively preventing the backflow of sputum or waste liquid in the testing vessel to the pipeline and pump body, avoiding cross-contamination, and ensuring the purity of reagents and the accuracy of test data.

[0022] Furthermore, the storage tanks independently store disinfectant, diluent, and rinsing solution. The storage tank containing rinsing solution is connected to the inlet of the high-pressure pump via a pipeline, the storage tank containing disinfectant is connected to the inlet of the micro peristaltic pump via a pipeline, and the storage tank containing diluent is connected to the inlet of the small metering pump via a pipeline.

[0023] Through the above technical solution, multiple storage tanks independently store disinfectant, diluent and rinsing solution, which can avoid cross-contamination of different reagents from the source, ensure the purity and effectiveness of each reagent, meet the aseptic operation requirements in medical scenarios, the high-pressure pump can meet the high-pressure spraying requirements of rinsing solution, the metering pump can accurately control the amount of diluent added, and the peristaltic pump can avoid corrosion or contamination caused by direct contact between disinfectant and pump body.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs a negative pressure suction mechanism and a waste liquid discharge mechanism. The negative pressure suction mechanism ensures the safety and pollution prevention of suctioning through a one-way valve and a high-efficiency filter. It achieves a compact structure and precise control of multiple detection tanks by means of the buffer tank embedding and gas path distributor design, thereby improving the stability of negative pressure and the convenience of operation. The waste liquid discharge mechanism solves the dynamic sealing problem by means of a rotary sealing joint to prevent leakage. It achieves compliant and efficient collection of waste liquid through the convergence and collection. The structure is adapted to the integrated layout of the turntable and is easy to maintain. (2) The present invention designs an analysis and processing mechanism. It achieves precise delivery of reagents through the corresponding connection of a dedicated pump body and a storage tank. It ensures uniform dilution and mixing of sputum and reduces residue by means of the optimized design of the stirring mechanism, coating and bristles. It achieves real-time detection and analysis of sputum indicators by means of the built-in sensor and signal processing module. Subsequently, it completes the process by means of the diversion ring and the directional nozzle. The test canister is rinsed and disinfected without dead angles. The entire process relies on the sealed structure and one-way valve design to block cross-contamination, which not only greatly improves the efficiency and data accuracy of sputum analysis and reduces the operating intensity of medical staff, but also fully meets the medical aseptic operation standards; (3) This invention designs an intermittent rotating mechanism, which cleverly realizes the periodic cycle of "transmission-stop" of the turntable through the meshing of the incomplete gear plate and the incomplete gear ring, so that multiple test canisters can be sequentially transferred to the work stations such as sputum suction, analysis, and drainage, and the corresponding operations are stably completed during the dwell stage, ensuring that the connection between each process is smooth and efficient. Moreover, the force is stable and the shaking is small during the transmission process, which can reduce the pulling and wear of connecting parts such as trachea and waste liquid pipe, and improve the overall operating stability of the device. This not only improves the automation level and work efficiency of the device, but also reduces the maintenance cost, and forms an efficient linkage with the negative pressure sputum suction, analysis and processing, and waste liquid discharge mechanisms.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figure 1 - Figure 5 As shown, an integrated sputum collection and analysis device for internal medicine in this embodiment includes a mobile cabinet 1. A display screen 2 and a sputum suction interface 3 are respectively installed on the top of the mobile cabinet 1. Two storage compartments 4 are installed inside the mobile cabinet 1. One storage compartment 4 contains multiple disposable suction tubes, and the other storage compartment 4 contains multiple waste tubes. A turntable 5 is rotatably connected inside the mobile cabinet 1.

[0029] like Figure 6 and Figure 7As shown, the mobile cabinet 1 is equipped with an intermittent rotation mechanism 6 for rotating the turntable 5. The intermittent rotation mechanism 6 includes a rotation motor 601 installed inside the mobile cabinet 1. An incomplete gear plate 602 is fixedly connected to the output end of the rotation motor 601. An incomplete gear ring 603 that mates with the incomplete gear plate 602 is fixedly connected to the bottom of the turntable 5. The diameter of the disc of the incomplete gear plate 602 is smaller than the inner diameter of the ring of the incomplete gear ring 603, and the incomplete gear plate 602 is embedded in the annular space of the incomplete gear ring 603. This embedding of the incomplete gear plate 602 in the annular space of the incomplete gear ring 603 makes the structure of the entire intermittent rotation mechanism 6 more compact, reducing its volume occupied inside the device and adapting to the limited installation space of the mobile cabinet 1. Multiple detection tanks 7 are installed on the top of the turntable 5, and a gravity transmission corresponding to the detection tanks 7 is installed inside the turntable 5. When the rotating motor 601 starts, the output of sensor 8 will drive the incomplete gear plate 602 to rotate synchronously. Since the incomplete gear plate 602 only has teeth in a local area, the power of the rotating motor 601 will be transmitted to the incomplete gear ring 603 only when the tooth area of ​​the gear plate meshes with the tooth area of ​​the incomplete gear ring 603 at the bottom of the turntable 5, thereby driving the turntable 5 to rotate together. When the incomplete gear plate 602 rotates to the smooth area without teeth, its meshing relationship with the incomplete gear ring 603 will be broken, the turntable 5 will lose power input and remain stationary. During the continuous operation of the rotating motor 601, the incomplete gear plate 602 and the incomplete gear ring 603 will periodically complete the cycle of "meshing transmission - disengagement and stop", ultimately realizing the intermittent rotation of the turntable 5 so that the detection tank 7 on the turntable 5 can complete the corresponding operation process during the stationary phase.

[0030] like Figure 8 and Figure 9As shown, the top of the turntable 5 is equipped with a negative pressure suction mechanism 9 for performing negative pressure suction on the test canister 7. The negative pressure suction mechanism 9 includes multiple tracheas 901 installed on the outer wall of the test canister 7. Each trachea 901 has a gas one-way valve 902 and a solenoid valve 903 installed on its outer wall. The other end of each trachea 901 is equipped with a gas distributor 904. A negative pressure buffer tank 905 is fixedly connected to the bottom of the gas distributor 904. The negative pressure buffer tank 905 is embedded in the internal groove of the turntable 5, and the top of the negative pressure buffer tank 905 is sealed to the bottom of the gas distributor 904 by a flange. The design fully utilizes the unused space inside the turntable 5, avoiding the buffer tank occupying additional device volume, allowing the negative pressure suction mechanism 9 and the turntable 5 to form a compact integrated layout, reducing space waste caused by the scattered installation of components. At the same time, the buffer tank rotates intermittently and synchronously with the turntable 5, which can prevent the trachea 901 from being pulled or twisted due to the rotation of the turntable 5, reduce the wear and leakage risk of the airway connection parts, and ensure the stability of negative pressure transmission. A negative pressure pipe 906 is installed on the outer wall of the negative pressure buffer tank 905 near the bottom. An adjustable speed oil-free vacuum pump 907 is installed at the other end of the negative pressure pipe 906, and a high-efficiency filter 908 is installed on one side of the adjustable speed oil-free vacuum pump 907.

[0031] like Figure 8 and Figure 9 As shown, the adjustable speed oil-free vacuum pump 907 is started, which evacuates the negative pressure buffer tank 905 through the negative pressure pipe 906, creating a stable negative pressure environment inside the buffer tank. When a certain detection tank 7 needs to be suctioned, the solenoid valve 903 on the outer wall of the corresponding trachea 901 opens simultaneously. The gas distributor 904 transmits the negative pressure in the negative pressure buffer tank 905 to the detection tank 7 through the trachea 901. At the same time, the gas one-way valve 902 on the trachea 901 prevents sputum or gas in the detection tank 7 from flowing back into the gas path. Under this negative pressure, sputum is sucked into the corresponding detection tank 7 for collection. During the process, the adjustable speed oil-free vacuum pump 907 can change the negative pressure intensity by adjusting the speed to adapt to different suctioning scenarios. The gas discharged by the adjustable speed oil-free vacuum pump 907 needs to be filtered through the high-efficiency filter 908 to prevent sputum aerosol from spreading and causing pollution.

[0032] like Figure 10As shown, the mobile cabinet 1 is equipped with a waste liquid discharge mechanism 10 for draining liquid. The waste liquid discharge mechanism 10 includes multiple check valves 1001 installed at the bottom of the testing tank 7. Each check valve 1001 has a waste liquid pipe 1002 fixedly connected to its bottom. A manifold 1003 is installed at the other end of each waste liquid pipe 1002. A rotary sealing joint rotating end 1004 is installed at the bottom of the manifold 1003. A rotary sealing joint fixing end 1005 is provided on the outer wall of the rotary sealing joint rotating end 1004. A waste liquid tank 1006 is fixedly connected to the bottom of the rotary sealing joint fixing end 1005. A drain pipe 1007 is fixedly connected to the bottom of the waste liquid tank 1006. After the sputum in the testing tank 7 is collected, analyzed, and rinsed, the corresponding test... When the check valve 1001 at the bottom of tank 7 is opened, the waste liquid inside the tank, aided by gravity and residual negative pressure, is collected into the manifold 1003 through the independent waste liquid pipes 1002. As the manifold 1003 rotates intermittently in sync with the turntable 5, the rotating end 1004 of the rotary sealing joint connected to its bottom will form a dynamic sealing fit with the fixed end 1005 of the rotary sealing joint, which ensures that the waste liquid channel is not interrupted when the turntable 5 rotates and prevents waste liquid leakage. Subsequently, the waste liquid flows into the waste liquid tank 1006 below through the fixed end 1005 of the rotary sealing joint for centralized storage. When the waste liquid in the waste liquid tank 1006 reaches the preset capacity, the waste liquid can be discharged and treated by opening the drain pipe 1007 at its bottom, so as to achieve orderly collection and compliant discharge of waste liquid.

[0033] like Figure 11 As shown, an electronic telescopic rod assembly 11 is installed on the inner wall of the mobile cabinet 1 near the top, and a bottle mouth sealing block 12 is fixedly connected to the output end of the electronic telescopic rod assembly 11.

[0034] like Figure 12 - Figure 21 As shown, the top of the bottle neck sealing block 12 is provided with an analysis and processing mechanism 13 for analyzing sputum. The analysis and processing mechanism 13 includes a protective cover 1301 installed on the top of the bottle neck sealing block 12. Inside the protective cover 1301, a micro peristaltic pump 1302, a signal processing module 1303, a small metering pump 1304, and a high-pressure pump 1305 are respectively installed. The bottom of the high-pressure pump 1305 is fixedly connected to a flushing pipe 1306, and the other end of the flushing pipe 1306 is fixedly connected to a diversion ring 1307. 1307 is an annular hollow cavity structure. The multiple rinsing nozzles 1308 at its bottom are all angled downwards at 45° towards the inner wall of the test tank 7. The flow distribution ring 1307 of the annular hollow cavity can evenly distribute the rinsing liquid to each rinsing nozzle 1308. The downward 45° spray angle can accurately cover the entire inner wall of the test tank 7, achieving rinsing without dead angles, effectively avoiding sputum residue and bacterial growth, and ensuring the cleaning and disinfection effect. Multiple evenly distributed rinsing nozzles 1308 are installed at the bottom of the flow distribution ring 1307.

[0035] like Figure 12 - Figure 21 As shown, a sealing head 1309 is installed near the center of the top of the bottle mouth sealing block 12. Two connecting pipes 1310 are fixedly connected to the top of the sealing head 1309. The two connecting pipes 1310 are respectively connected to a micro peristaltic pump 1302 and a small metering pump 1304. A stirring motor 1311 is installed inside the bottle mouth sealing block 12. A drive gear 1312 is fixedly connected to the output end of the stirring motor 1311. A transmission gear ring 1313 that meshes with the drive gear 1312 is rotatably connected to the top of the bottle mouth sealing block 12. A hollow tube 1314 is fixedly connected to the bottom of the transmission gear ring 1313. The outer wall of the hollow tube 1314 and the inner wall of the detection tank 7 are both coated with a medical-grade ceramic coating. The polytetrafluoroethylene coated nylon bristles 1315 are arranged in a spiral pattern. A diaphragm-type one-way valve is installed inside each of the multiple drainage holes 1316. The medical-grade ceramic coating has excellent biocompatibility, wear resistance and low surface area. The surface energy significantly reduces the risk of sputum and reagents adhering to the outer wall of the hollow tube 1314 and the inner wall of the test tank 7, reducing residual contamination. It also withstands long-term friction of the bristles without easily breaking and is easily cleaned by rinsing liquid. The spirally sparse arrangement of the PTFE-coated nylon bristles 1315 creates a spiral shear force during stirring, improving the uniformity of mixing sputum and diluent, while avoiding the accumulation of liquid residue caused by dense arrangement. Combined with the non-stick properties of the coating, it further reduces the probability of contaminant adhesion. The diaphragm-type one-way valve in the drain hole 1316 can precisely control the one-way release of diluent and disinfectant, effectively preventing the backflow of sputum or waste liquid from the test tank 7 into the pipeline and pump body, avoiding cross-contamination, and ensuring reagent purity and test data accuracy. PTFE-coated nylon bristles 1315 are installed on the bottom of the outer wall of the hollow tube 1314, and multiple drain holes 1316 are opened on the bottom of the outer wall of the hollow tube 1314.

[0036] like Figure 12 - Figure 21As shown, two external bearings 1317 are installed between the hollow tube 1314 and the bottle mouth sealing block 12. A release tube 1318 is installed inside the hollow tube 1314, and two internal bearings 1319 are installed between the hollow tube 1314 and the release tube 1318. The bottoms of two connecting tubes 1310 are sleeved inside the release tube 1318. A protective tube 1320 is installed inside the release tube 1318. Two data cable bundle tubes 1321 are installed inside the protective tube 1320. One end of the data cable bundle tube 1321 is connected to the RGB color sensor 1322 and the viscosity sensor 1323, respectively, and the other end of the data cable bundle tube 1321 is connected to the signal processing module 1303. Multiple storage tanks 14 are fixedly connected inside the mobile cabinet 1. Each storage tank 14 independently stores disinfectant, diluent, and rinsing solution. The storage tank 14 containing rinsing solution is connected to the inlet of the high-pressure pump 1305 via a pipeline. The storage tank 14 containing disinfectant is connected to the inlet of the micro peristaltic pump 1302 via a pipeline. The storage tank 14 containing diluent is connected to the inlet of the small metering pump 1304 via a pipeline. The independent storage of disinfectant, diluent, and rinsing solution by multiple storage tanks 14 can avoid cross-contamination of different reagents from the source, ensure the purity and effectiveness of each reagent, and meet the aseptic operation requirements in medical scenarios. The high-pressure pump 1305 can meet the high-pressure spray requirements of the rinsing solution, the metering pump can accurately control the amount of diluent added, and the peristaltic pump can avoid corrosion or contamination caused by direct contact between the disinfectant and the pump body.

[0037] like Figure 12 - Figure 21As shown, when the test tank 7 rotates intermittently with the turntable 5 to the analysis station and is sealed by the sealing head 1309 on the top of the bottle mouth sealing block 12, the small metering pump 1304 inside the protective cover 1301 is first started to deliver a quantitative amount of diluent from the storage tank 14 to the release pipe 1318 through the corresponding connecting pipe 1310, and then evenly injects it into the sputum in the test tank 7 through multiple drainage holes 1316 on the outer wall of the hollow pipe 1314. Subsequently, the stirring motor 13 inside the bottle mouth sealing block 12... When 11 is activated, the drive gear 1312 at its output end drives the meshing transmission gear ring 1313 to rotate, which in turn drives the hollow tube 1314, which is fixedly connected to the transmission gear ring 1313, to rotate synchronously. The hollow tube 1314 maintains a stable rotational engagement with the bottle mouth sealing block 12 through the external bearing 1317, and forms a relative rotation with the fixed release tube 1318 through the internal bearing 1319, avoiding tube entanglement. The polytetrafluoroethylene-coated nylon bristles on the outer wall of the hollow tube 1314 As the tube rotates, sputum and diluent are thoroughly mixed, completing the sputum dilution pretreatment. After dilution, the two data cable bundles 1321 inside the protective tube 1320 of the release tube 1318 are connected to the RGB color sensor 1322 and the viscosity sensor 1323 respectively. The collected sputum dilution color and viscosity data are transmitted in real time to the signal processing module 1303 for analysis and detection, generating detection results. After detection, the micro peristaltic pump 1302 is started to deliver the disinfectant in the storage tank 14 to the detection tank 7 through another connecting tube 1310 for disinfection. At the same time, the high-pressure pump 1305 delivers the rinsing liquid to the diverting ring 1307 through the rinsing pipe 1306. The liquid is then sprayed onto the inner wall of the detection tank 7 and the bristles of the hollow tube 1314 through multiple evenly distributed rinsing nozzles 1308 at its bottom. With the continuous rotation of the bristles, efficient rinsing and disinfection of the inside of the detection tank 7 are achieved, ensuring sealing performance throughout the process and preventing waste liquid leakage or aerosol diffusion.

[0038] The working principle of this embodiment is as follows: The operator takes out a disposable suction tube and connects it to the suction interface 3. At the same time, the adjustable speed oil-free vacuum pump 907 is started. A stable negative pressure is formed by evacuating the negative pressure buffer tank 905 embedded inside the turntable 5 through the negative pressure pipe 906. At this time, the solenoid valve 903 on the trachea 901 corresponding to the empty detection tank 7 opens, and the gas distributor 904 transmits the negative pressure to the detection tank 7. Sputum is drawn into the tank under the negative pressure. The gas one-way valve 902 on the trachea 901 prevents sputum backflow. The exhaust gas is filtered by the high-efficiency filter 908 to avoid aerosol contamination. The gravity sensor 8 at the bottom of the turntable 5 detects the weight of the sputum in real time and feeds it back to the display screen 2. After suctioning is completed, the... The rotating motor 601 of the intermittent rotating mechanism 6 drives the incomplete gear plate 602 to rotate, which periodically meshes with the incomplete gear ring 603 at the bottom of the turntable 5, causing the turntable 5 to intermittently rotate with the sputum-containing test canister 7 to the analysis station and then stop. At the same time, the empty test canister 7 rotates to the suction station to wait for use. Then, the electronic telescopic rod assembly 11 pushes the bottle mouth sealing block 12 down, and the bottle mouth of the test canister 7 is sealed through the sealing head 1309. The analysis and processing mechanism 13 is started: the small metering pump 1304 injects the quantitative diluent into the test canister 7 through the connecting pipe 1310, the release pipe 1318 and the drain hole 1316 of the hollow pipe 1314, with a built-in diaphragm one-way valve to prevent backflow. The stirring motor 1311 is activated. Driven by the drive gear 1312 and transmission gear ring 1313, the hollow tube 1314 rotates. The sparsely arranged, spirally arranged polytetrafluoroethylene-coated nylon bristles 1315 on its outer wall, in conjunction with the medical-grade ceramic coating on the inner wall of the hollow tube 1314 and the detection container 7, thoroughly mix the sputum and diluent. Then, the RGB color sensor 1322 and viscosity sensor 1323 transmit the collected sputum diluent data to the signal processing module 1303 via the data cable bundle tube 1321. The analysis results are displayed in real-time on the display screen 2. After the detection is complete, the micro peristaltic pump 1302 injects disinfectant into the detection container 7 through another connecting tube 1310, while the high-pressure pump 1305 pumps the rinsing solution through… The flushing pipe 1306 delivers the sputum to the diversion ring 1307 of the annular hollow cavity. The sputum is then sprayed onto the inner wall and brush bristles of the testing tank 7 through multiple downward-angled 45° flushing nozzles 1308. The continuous rotation of the brush bristles ensures thorough flushing and disinfection. Finally, the check valve 1001 at the bottom of the testing tank 7 opens, and the waste liquid is collected through the waste liquid pipe 1002 into the manifold 1003 under the action of gravity and residual negative pressure. The waste liquid then flows into the waste liquid tank 1006 for centralized storage through the dynamic sealing cooperation between the rotating end 1004 and the fixed end 1005 of the rotary sealing joint. Once the waste liquid reaches the preset capacity, it is discharged through the drain pipe 1007 for treatment, completing the entire process of sputum collection, analysis, disinfection flushing, and waste liquid discharge.
