Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a precise lower digestive tract pathological specimen collector. Background Art

[0002] In the medical field, especially during the diagnosis of digestive system diseases, the collection and preservation of lower digestive tract pathological specimens are crucial. Traditional methods for collecting lower digestive tract pathological specimens are often relatively simple and crude. For example, ordinary containers are used for collection, lacking effective fixation and monitoring and regulation of the specimen preservation environment.

[0003] Most traditional lower digestive tract pathological specimen collection boxes are designed mainly for simple accommodation functions, and insufficient consideration is given to the fixation and stability of specimens during collection, transportation, and temporary storage. In actual application scenarios, the collection box may experience various situations. For example, after medical staff collect the specimens, they need to carry the collection box to different departments for submission for inspection, during which shaking, collision, and other situations will inevitably occur; or during transportation, external forces such as vehicle bumps and vibrations will also affect the collection box.

[0004] Due to the lack of effective fixation structures and stable guarantee mechanisms in traditional collection boxes, specimens are prone to displacement, shaking, and even mutual collision inside the box under these external interferences. This is very likely to cause damage to the specimens, such as the destruction of the tissue structure of the specimens and the deformation of cell morphology, etc., thereby affecting the accuracy of pathological test results. Moreover, once the specimens are damaged, all subsequent detection and diagnosis work based on these specimens will lose a reliable basis, which may lead to serious consequences such as misdiagnosis and missed diagnosis, causing great obstacles to the treatment of patients' diseases.

[0015] The communication and external interaction module is used to transmit information such as specimen-related data and device operating status recorded in the specimen collector to external devices through common communication interfaces such as USB, Bluetooth, and Wi-Fi equipped.

[0016] Preferably, the control core module includes: a micro-control unit, which is responsible for receiving signals transmitted from each sensor acquisition module and processing and analyzing these signals using its own computing power.

[0017] Preferably, the sensor signal acquisition module includes:

[0018] A temperature sensor unit, which is used to monitor the temperature inside the precise lower digestive tract pathological specimen collector in real time, convert the collected temperature-related physical signals into electrical signals, and transmit them to the micro-control unit after being processed by the corresponding interface circuit;

[0019] A humidity sensor unit, which is used to monitor the air humidity inside the precise lower digestive tract pathological specimen collector in real time, convert the detected humidity physical quantity into a corresponding electrical signal, and then transmit it to the micro-control unit after being processed by the supporting signal processing circuit;

[0021] Preferably, the data processing and analysis module includes:

[0022] A data fusion algorithm unit, which is used to comprehensively process multi-source data collected from different sensors;

[0023] A threshold judgment and alarm mechanism unit, which is used to compare the data collected by the sensor with various preset thresholds. Once the data exceeds the corresponding reasonable range, the alarm function will be immediately triggered;

[0024] A status recording and data analysis unit, which is used to record in real time the data collected by each sensor and the corresponding timestamp information during the operation of the precise lower digestive tract pathological specimen collector, and form a detailed operation log.

[0025] Preferably, the execution control module includes:

[0026] A temperature regulation control unit, which is used to receive relevant instructions from the control system, drive the temperature regulation device to work and adjust the internal temperature according to the comparison result between the internal temperature of the specimen collector fed back by the temperature sensor and the preset appropriate temperature range;

[0027] A humidity regulation control unit, which is used to drive the humidity regulation device to work and regulate the internal humidity according to the instructions transmitted by the control system and the internal humidity of the specimen collector fed back by the humidity sensor, in contrast to the preset appropriate humidity range;

[0028] The specimen processing prompt control unit is used to, based on the judgment made by the control system according to the data transmitted by various sensors, when situations such as the liquid level in the liquid cavity approaching the upper limit or specimens being placed occur during the specimen collection process, send prompt information to the user in a timely manner to remind them to perform operations such as specimen cleaning, transfer, or recording relevant information.

[0029] Preferably, the communication and external interaction module includes:

[0030] The data transmission interface unit is used to, by means of common communication methods such as USB, Bluetooth, and Wi-Fi, be responsible for transmitting information such as specimen-related data and equipment operating status recorded inside the precise lower digestive tract pathological specimen collector to external devices;

[0031] The remote control unit is used to establish a connection channel through the communication and external interaction module. On the premise of having corresponding permissions and a security authentication mechanism, it enables users such as medical staff to remotely send control instructions to the precise lower digestive tract pathological specimen collector through external devices.

[0032] Working principle: In the sensor signal acquisition module, the temperature sensor unit continuously monitors the internal temperature and converts the physical signal into an electrical signal and transmits it to the micro control unit; the humidity sensor unit monitors the humidity and converts and transmits the corresponding electrical signal; the liquid level sensor unit tracks the change in the liquid level height of the liquid cavity and also converts and transmits the electrical signal.

[0033] After the micro control unit receives the signals from each sensor, the data processing and analysis module starts to function. The data fusion algorithm unit comprehensively processes multi-source data, removes redundant errors, and makes the information more accurate. The threshold judgment and alarm mechanism unit compares the data with the preset threshold, and triggers an alarm when it exceeds the range to prompt the user to pay attention to the abnormality. The status recording and data analysis unit records the data and time stamps in real time to form a log, and also analyzes the data to master the status changes.

[0034] The execution control module acts according to the above judgment results. The temperature regulation control unit drives the temperature regulation equipment according to the instructions to maintain an appropriate temperature; the humidity regulation control unit controls the internal humidity according to the preset humidity range; the specimen processing prompt control unit sends prompts to the user in a timely manner in situations such as the liquid level approaching the upper limit for operation.

[0035] In the communication and external interaction module, the data transmission interface unit transmits specimen-related data and equipment status to external devices by means of USB, Bluetooth, Wi-Fi, etc. The remote control unit allows users to remotely send control instructions to operate the collector after the permissions and security authentication are passed. At the same time, structural components such as the box, the box body, and the placement board cooperate with each other. The handle is convenient for carrying, the buckle and the hook are firmly connected, and the placement board provides buffer protection, jointly ensuring the stable operation of the collector and creating good conditions for the proper collection and preservation of lower digestive tract pathological specimens.

[0036] Meanwhile, in terms of the collector structure, components such as the inner shell, connecting rod, and spring cooperate. After the specimen is placed in the collection box and the box is put back into the inner shell, fixation is achieved through operations such as pressing. The handle, buckle, etc. ensure convenient overall handling and structural stability, and the placement plate and sandwich sponge also play a role in buffering and positioning. All parts work together to ensure the proper collection, preservation, and management of lower digestive tract pathological specimens.

[0037] The present invention provides a precise lower digestive tract pathological specimen collector, which has the following beneficial effects:

[0038] 1. Through such an operation and structural cooperation mechanism, the present invention realizes the effect that the collection box can be conveniently installed and disassembled before and after specimen collection, and can be firmly fixed after installation. This convenient fixing and disassembling method also facilitates the daily operation and use of medical staff, improving work efficiency. It solves the problem of unstable fixation of traditional lower digestive tract pathological specimen collection boxes.

[0039] 2. Through the setting of the handle, when medical staff carry the entire specimen collector, they can conveniently and comfortably hold the handle for lifting operation, making the handling process more convenient and labor-saving. Moreover, the fixing structure of the handle ensures that it remains stable and reliable under the condition of bearing a certain weight of the collector and the internal specimen, etc., without loosening, breaking, etc. It solves the problems of inconvenient handling and unstable structural connection of traditional collection devices.

[0040] 3. Through the positioning function of the placement groove on the upper surface of the placement plate, the collection-related components placed on it can be arranged more neatly and orderly, ensuring the relative position stability of each component in the collector and reducing problems such as mutual collision that may occur due to random placement. The buffering effect of the sponge in the sandwich of the placement plate ensures the integrity of the pathological specimens stored in the collection box. It solves the problem of insufficient buffering and protection in traditional lower digestive tract pathological specimen collection devices.

[0041] 4. Through the processing and analysis of the signals transmitted by each sensor acquisition module by the micro control unit, the present invention can accurately and in real time grasp the actual situation of various key parameters inside the specimen collector. It can accurately know whether the current internal temperature is within the range that can ensure the proper preservation of pathological specimens, whether the humidity is appropriate to avoid problems such as mildew or drying of the specimens, and whether the liquid level in the liquid cavity is normal to prevent abnormal situations such as liquid overflow. It solves the problem of the lack of precise monitoring, analysis, and judgment of the internal environment and related parameters in traditional lower digestive tract pathological specimen collection devices.

[0042] 5. Through the temperature, humidity, and liquid level sensor units, the microcontroller unit of the present invention can accurately and in real time obtain the temperature value inside the specimen collector, the real-time state of the air humidity, and the liquid level height. When an abnormality occurs, the user can be reminded in time to take corresponding measures, solving the problem that the traditional lower digestive tract pathological specimen collection device cannot monitor the internal key environmental parameters in real time and accurately.

Specific embodiments

[0057] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] Please refer to the attached Figure 2 - attached Figure 7 , an embodiment of the present invention provides a precise lower digestive tract pathological specimen collector, including a box 1, a box body 3 is provided at the bottom end of the box 1, an outer shell 7 is provided inside the box body 3, a first guiding block 16 is provided in the middle of the inner wall of the outer shell 7, a second guiding block 17 is provided on one side of the inner wall of the outer shell 7, a spring 15 is provided at the bottom end of the inner wall of the outer shell 7, the top end of the spring 15 is provided with an inner shell 11, sliding blocks 12 are fixedly provided on both sides of the inner shell 11, the outer wall of the inner shell 11 is rotationally connected to a connecting rod 13 through a second rotating shaft, one end of the connecting rod 13 is rotationally connected to a first rotating shaft 14, the outer wall of the first rotating shaft 14 is slidably connected to the edges of the first guiding block 16 and the second guiding block 17, clamping blocks 10 are symmetrically provided at the top end of the inner shell 11, a collection component is provided inside the inner shell 11, the collection component includes a collection box 19, the outer wall of the collection box 19 is slidably connected inside the inner shell 11, a top cover 9 is provided at the top end of the collection box 19, clamping grooves are provided on both sides of the top cover 9, a filter plate 20 is provided inside the collection box 19, a plurality of holes are provided on the upper surface of the filter plate 20, a specimen cavity 21 is provided above the filter plate 20, a liquid cavity 22 is provided below the filter plate 20, a heat-conducting silica gel sheet 18 is provided at the bottom end of the collection box 19, and the bottom end of the heat-conducting silica gel sheet 18 is provided at the bottom end of the inner wall of the inner shell 11.

[0059] Specifically, when collecting pathological specimens, the top cover 9 and the collection box 19 can be conveniently taken out from the inner shell 11. The specific operation is to draw them outwards along the sliding connection structure between the inside of the inner shell 11 and the collection box 19. Subsequently, open the top cover 9, and at this time, the pathological sample can be accurately placed inside the collection box 19. Here, the inside of the collection box 19 is divided into a specimen chamber 21 and a liquid chamber 22 by a filter plate 20, and the specimen is placed in the specimen chamber 21. After the collection is completed, cover the top cover 9. Its good sealing design can effectively seal the space where the specimen is located, preventing foreign impurities from entering and the internal specimen from being contaminated.

[0060] Then put the collection box 19 into the inner shell 11. Subsequently, the medical staff presses firmly on the upper surface of the top cover 9. The thrust applied will be transmitted to the collection box 19 and then act on the inner shell 11, causing the whole inner shell 11 to be pressed downwards. During the process of the inner shell 11 moving downwards, it will squeeze the spring 15 connected to its bottom end. The spring 15 starts to compress due to the force and stores elastic potential energy to buffer this pressing force.

[0061] The connecting rod 13 rotatably connected to the outer wall of the inner shell 11 through the second rotating shaft, and the first rotating shaft 14 rotatably connected to one end of the connecting rod 13 will also move downwards synchronously with the inner shell 11. During the movement, the first rotating shaft 14 will touch the slope of the first guiding block 16. Due to the special shape design of the slope, when the first rotating shaft 14 continues to move along the slope, it will rotate around its connection point with the connecting rod 13. And through this linkage relationship, the connecting rod 13 will also rotate through the second rotating shaft, thereby changing its original moving angle and adapting to the angle change along the slope of the first guiding block 16. When the first rotating shaft 14 moves to the edge of the slope of the first guiding block 16, under the action of the elastic restoring force of each component and the mutual restriction of the structure, the second rotating shaft will drive the connecting rod 13 to reset, making the connecting rod 13 return to a relatively initial angular state. At this time, the reset first rotating shaft 14 will be stuck in the groove of the first guiding block 16, playing a temporary limiting role to restrict the inner shell 11 from moving upwards randomly without external interference.

[0062] During the entire process of the inner shell 11 moving downwards, the outwardly flared clamping block 10 at the top of the inner shell 11 will also move downwards together. When the clamping block 10 touches the edge of the outer shell 7, due to the limiting effect of the edge of the outer shell 7, an inward squeezing force will be applied to the clamping block 10, forcibly retracting the clamping block 10 and changing its angle from outwardly flared to vertical. And the changed clamping block 10 can just be accurately engaged with the clamping grooves on both sides of the top cover 9, thereby firmly fixing the collection box 19 inside the inner shell 11, completing the entire clamping operation, and ensuring that the collection box 19 can maintain a stable state during subsequent handling, transportation, etc.

[0063] When it is necessary to take out the collection box 19, medical staff can apply an appropriate external force to the top cover 9 again. This external force will be transmitted to the inner shell 11 through the collection box 19, causing the first rotating shaft 14 that was originally stuck in the groove of the first guiding block 16 to be subjected to the external force and break away from the groove, and then move along the slope of the second guiding block 17. When the medical staff releases their hand, under the action of the elastic restoring force of the spring 15, the inner shell 11 will tend to move upward. At this time, the first rotating shaft 14 will rise along another slope of the first guiding block 16 until it returns to the position before being pressed, and each component will complete the reset operation accordingly. In this way, the collection box 19 can be taken out of the inner shell 11 again, facilitating subsequent operations such as specimen processing.

[0064] Through such an operation and structural cooperation mechanism, it is realized that the collection box 19 can be conveniently installed and disassembled before and after specimen collection, and can be firmly fixed after installation. After the specimen collection is completed, through the above-mentioned pressing and clamping operations, during the subsequent short-distance transfer of the collection device by medical staff between different departments within the hospital or long-distance transportation by transportation means, the collection box 19 will not easily become loose or displaced and other unstable situations. This convenient fixing and disassembling method also facilitates the daily operation and use of medical staff, improves work efficiency, and the movement and cooperation of each component are relatively smooth during the whole process, without situations such as jamming that affect the use. It solves the problem of unstable fixation of traditional lower digestive tract pathological specimen collection boxes.

[0065] Please refer to the appendix Figure 1 - appendix Figure 3 On the upper surface of the box 1, a handle 2 is fixedly arranged. On both sides of the outer wall of the box 1, hooks 4 are provided. On both sides of the outer wall of the box body 3, buckles 5 are provided. One end of the buckle 5 is arranged on one side of the hook 4.

[0066] Specifically, on the upper surface of the box 1, a handle 2 is fixedly arranged. The handle 2 and the box 1 are fixed together by a stable connection method, providing a part for the user to easily grasp and apply force. And on both sides of the outer wall of the box 1, hooks 4 are provided. Correspondingly, on both sides of the outer wall of the box body 3, buckles 5 are provided. One end of the buckle 5 can be placed on one side of the hook 4. When it is necessary to assemble and fix the box 1 and the box body 3, the user can manually operate to align one end of the buckle 5 with the hook 4 and make it embed into a suitable position on one side of the hook 4. Relying on the elastic deformation of the buckle 5 itself and the clamping structure with the hook 4, the two are tightly connected together, thus realizing the stable assembly of the box 1 and the box body 3. Similarly, when it is necessary to separate the box 1 and the box body 3, apply an appropriate external force to make the buckle 5 overcome the resistance generated by its own elastic deformation and break away from one side of the hook 4, and the disassembly operation can be completed.

[0067] With the provision of the handle 2, when medical staff carry the entire specimen collector, they can conveniently and comfortably hold the handle 2 for lifting and carrying operations, making the handling process more convenient and labor-saving. Moreover, the fixing structure of the handle 2 ensures that it remains stable and reliable under the condition of bearing a certain weight of the collector and the internal specimens, etc., without loosening, breaking or other situations. It solves the problems of inconvenient handling and unstable structural connection of traditional collection devices.

[0068] Please refer to the attached Figure 2 -attached Figure 3 , inside the box body 3, there is a placement plate 6. On the upper surface of the placement plate 6, there are several placement grooves. On the lower surface of the placement plate 6, there is a sandwich layer 8. Inside the sandwich layer 8 of the placement plate 6, there is a sponge, and the bottom end of the sponge is set at the bottom end of the inner wall of the box body 3.

[0069] Specifically, the upper surface of the placement plate 6 is designed with several placement grooves. These placement grooves have specific shapes and sizes, which can be adapted to the inner shell 11, enabling the corresponding components to be accurately embedded into the placement grooves, thereby realizing the preliminary positioning and placement function.

[0070] And the lower surface of the placement plate 6 is provided with a sandwich layer 8, and a sponge is placed inside this sandwich layer 8. The sponge itself has good elasticity and buffering performance, and its bottom end is directly in contact with the bottom end of the inner wall of the box body 3. When the entire collector is subjected to external impacts, such as being collided during handling or vibrating due to bumps during transportation, the external force will first be transmitted to the box body 3 and then act on the placement plate 6. At this time, the sponge inside the sandwich layer 8 of the placement plate 6 will rely on its own elastic deformation to absorb and buffer a part of the external force, reducing the external force transmitted to the upper surface of the placement plate 6 and the related components placed in the placement grooves, and avoiding damage to the components placed on the placement plate 6 or unstable situations such as displacement due to excessive external force.

[0071] Through the positioning function of the placement grooves on the upper surface of the placement plate 6, the collection-related components placed on it can be placed more neatly and orderly, facilitating medical staff to manage and operate each component. At the same time, it also ensures the relative position stability of each component inside the collector, reducing problems such as mutual collision that may occur due to random placement. And the buffering effect of the sponge inside the sandwich layer 8 of the placement plate 6 effectively reduces the impact force on the internal components of the entire collector in the face of various external force interferences. For example, key components such as the inner shell 11 and the collection box 19 placed in the placement grooves can maintain a relatively stable state and will not easily shake or shift due to external forces, thus ensuring the integrity of the pathological specimens stored in the collection box 19. It solves the problem of insufficient buffer protection in traditional lower digestive tract pathological specimen collection devices.

[0072] Please refer to the attached Figure 8 -attached Figure 13, a precise lower digestive tract pathological specimen collection system, for a precise lower digestive tract pathological specimen collector, including the following systems:

[0073] The control core module is used to receive signals transmitted from various sensor units, process and analyze this information using data fusion algorithms, record relevant data for subsequent analysis, and at the same time send instructions to execution control modules such as temperature regulation, humidity regulation, specimen processing prompt, and structural protection;

[0074] The sensor signal acquisition module is used to process the original signals obtained by temperature, humidity, and liquid level sensors through corresponding interface circuits, convert them into digital signals or standard electrical signals that can be recognized by the microcontroller, and then transmit them to the control core unit;

[0075] The data processing and analysis module is used to comprehensively process the multi-source data transmitted from the sensor signal acquisition module using data fusion algorithms to eliminate errors and redundant information;

[0076] The execution control module is used to receive instructions transmitted from the data processing and analysis module and drive the corresponding execution devices to work according to the judgment results of the internal state of the specimen collector;

[0077] The communication and external interaction module is used to transmit information such as specimen-related data and device operation status recorded in the specimen collector to external devices through common communication interfaces such as USB, Bluetooth, and Wi-Fi equipped.

[0078] The control core module includes: a micro control unit, which is responsible for receiving signals transmitted from each sensor acquisition module and processing and analyzing these signals using its own computing power.

[0079] Specifically, it establishes a stable connection with each sensor acquisition module (such as temperature sensors, humidity sensors, liquid level sensors, etc.) through pre-set communication lines and interfaces. When these sensor acquisition modules monitor different physical quantities such as temperature, humidity, and liquid level at corresponding positions in the specimen collector and obtain corresponding signals, they will send these analog signals or digital signals along the established transmission lines to the micro control unit. For the signal reflecting the internal temperature of the specimen collector transmitted by the temperature sensor, the micro control unit will perform a comparison operation with the pre-set temperature range value suitable for specimen preservation; for the humidity signal transmitted by the humidity sensor, it will also perform corresponding data analysis with reference to the set reasonable humidity range; for the liquid level signal transmitted by the liquid level sensor, it will also judge whether it is within the normal range, etc. Through such a series of operations such as calculation, comparison, and logical judgment, to accurately analyze the actual state information represented by these signals.

[0080] Through the processing and analysis of the signals transmitted by each sensor acquisition module by the micro-control unit, the actual situations of various key parameters inside the specimen collector can be grasped in real time and accurately. For example, it can be accurately known whether the current internal temperature is within the range that can ensure the proper preservation of pathological specimens, whether the humidity is appropriate to avoid problems such as mildew or drying of specimens, and whether the liquid level in the liquid cavity is normal to prevent abnormal situations such as liquid overflow. It solves the problem that the traditional lower digestive tract pathological specimen collection device lacks accurate monitoring, analysis and judgment of the internal environment and related parameters.

[0081] The sensor signal acquisition module includes:

[0082] A temperature sensor unit for real-time monitoring of the temperature inside the precise lower digestive tract pathological specimen collector, converting the collected temperature-related physical signals into electrical signals, and transmitting them to the micro-control unit after being processed by the corresponding interface circuit;

[0083] A humidity sensor unit for real-time monitoring of the air humidity inside the precise lower digestive tract pathological specimen collector, converting the detected humidity physical quantity into a corresponding electrical signal, and then transmitting it to the micro-control unit after being processed by the supporting signal processing circuit;

[0084] A liquid level sensor unit for real-time monitoring of the liquid level height of the liquid cavity 22 in the precise lower digestive tract pathological specimen collector, converting the liquid level change into a corresponding electrical signal, and transmitting it to the micro-control unit after being processed by the adapted signal processing circuit.

[0085] Specifically, the temperature sensor unit utilizes its own temperature-sensitive physical characteristics to sense the temperature of the surrounding environment. In the internal environment of the specimen collector, the temperature will change due to factors such as external environmental influence, possible heat sources or cooling sources inside. The temperature sensor can capture these subtle temperature changes in real time. Based on physical effects such as thermal resistance and thermocouple, the collected temperature physical signal is converted into a corresponding electrical signal. Subsequently, this electrical signal is transmitted along the pre-connected wire to the corresponding interface circuit, and the interface circuit will perform processing operations such as filtering and amplification on it, removing the interference components in the signal and enhancing the signal strength, so that it can be transmitted to the micro-control unit in a more stable and accurate state for subsequent analysis and judgment.

[0086] The humidity sensor unit has a sensitive response mechanism to air humidity. When the air humidity inside the collector changes, such as due to the evaporation of moisture from the specimen or the infiltration of external air, causing the humidity to change, the humidity sensor will accurately convert the detected humidity physical quantity into a corresponding electrical signal based on its own moisture absorption and desorption characteristics, as well as the principles of capacitance and resistance changing with humidity. Then, this electrical signal will pass through a dedicated signal processing circuit that is matched with it. The signal processing circuit will condition the electrical signal according to established procedures and rules, such as calibrating its numerical range, removing noise interference, etc., and then transmit the processed electrical signal to the micro - control unit, providing a reliable data source for the micro - control unit to know the internal humidity situation.

[0087] The liquid - level sensor unit monitors the change in the liquid - level height in the liquid chamber 22 in real - time through different liquid - level detection principles such as ultrasonic, float, and capacitance (depending on the specific type of liquid - level sensor used). When the liquid level in the liquid chamber 22 changes due to an increase in the exudate of the specimen or the inflow and outflow of liquid during the collection process, the liquid - level sensor can quickly convert this liquid - level change into a corresponding electrical signal. Then, this electrical signal will be processed by a matching signal processing circuit. The matching signal processing circuit will optimize the electrical signal according to the output characteristics of the liquid - level sensor, such as amplifying the weak electrical signal to an appropriate amplitude range, linearizing the non - linear electrical signal, etc., and finally transmit the processed electrical signal to the micro - control unit to facilitate the micro - control unit to accurately judge the liquid - level situation.

[0088] Through the temperature, humidity, and liquid - level sensor units, the micro - control unit can accurately and real - time master the internal temperature value, the real - time state of air humidity, and the liquid - level height of the specimen collector. When an abnormality occurs, it can promptly remind the user to take corresponding measures. It solves the problem that traditional lower - digestive - tract pathological specimen collection devices cannot monitor key internal environmental parameters in real - time and accurately.

[0089] The data processing and analysis module includes:

[0090] The data fusion algorithm unit is used to comprehensively process multi - source data collected from different sensors;

[0091] The threshold judgment and alarm mechanism unit is used to compare the data collected by the sensors with various pre - set thresholds. Once the data exceeds the corresponding reasonable range, the alarm function will be immediately triggered;

[0092] The status recording and data analysis unit is used to record in real - time the data collected by each sensor and the corresponding timestamp information during the operation of the precision lower - digestive - tract pathological specimen collector, forming a detailed operation log.

[0093] Specifically, the data fusion algorithm unit first receives multi-source data collected from different sensors (such as temperature sensors, humidity sensors, liquid level sensors, etc.) through a preset data receiving channel. Due to different sensor types and measurement principles, these data vary in format, accuracy, time synchronization, etc. The data fusion algorithm unit will comprehensively process these multi-source data according to specific fusion algorithms such as weighted average method, Kalman filtering method, Bayesian estimation, etc.

[0094] The threshold judgment and alarm mechanism unit internally pre-stores various reasonable threshold ranges set for different sensor data. These thresholds are determined based on the optimal environmental conditions required for the proper preservation of lower digestive tract pathological specimens and the parameter requirements for the normal operation of the collector. When the data collected from the sensors is transmitted, this unit will compare each received data (such as temperature data, humidity data, liquid level data, etc.) with the corresponding preset threshold one by one. Once a certain data exceeds its corresponding reasonable range, for example, the temperature is higher than the maximum temperature threshold that the specimen can tolerate, or the humidity is lower than the minimum humidity threshold to prevent the specimen from drying, or the liquid level exceeds the maximum liquid level threshold that the liquid chamber can accommodate, etc., the alarm function will be immediately triggered.

[0095] The status recording and data analysis unit is always in a working state. It obtains the data collected by each sensor and the corresponding timestamp information in real time through a stable communication link established with each sensor. Each time the data is collected, it will be accurately recorded, and the specific time point when the data is obtained will be recorded along with it. These information will be stored in the internal storage medium in a certain format, and gradually form a detailed operation log over time.

[0096] Through the operation of the data fusion algorithm unit, it can provide a more reliable and accurate data basis for subsequent various decisions and controls. The multi-source data after fusion processing enables users to more comprehensively and accurately understand the actual environmental state inside the specimen collector, avoiding making wrong judgments due to the limitations or errors of single-sensor data, and thus helping to more scientifically regulate the specimen preservation environment and improve the quality and safety of specimen preservation. It solves the deficiencies of traditional lower digestive tract pathological specimen collection devices in data processing, abnormal warning, and operation status recording and analysis.

[0097] The execution control module includes:

[0098] The temperature regulation control unit is used to receive relevant instructions from the control system, and drive the temperature regulation device to work and adjust the internal temperature according to the comparison result between the internal temperature of the specimen collector feedback by the temperature sensor and the preset appropriate temperature range;

[0099] A humidity regulation control unit, which is used to drive a humidity regulation device to work according to the instructions transmitted by a control system and the internal humidity condition of a specimen collector feedback by a humidity sensor, and compare with a preset suitable humidity range to regulate the internal humidity;

[0100] A specimen processing prompt control unit, which is used to, according to the judgment made by the control system based on the data transmitted by various sensors, when situations such as the liquid level in the liquid cavity 22 approaching the upper limit or a specimen being placed occur during the specimen collection process, timely send a prompt message to the user to remind him / her to clean, transfer the specimen or record relevant information.

[0101] Specifically, the temperature regulation control unit maintains a stable communication connection with the control system and a temperature sensor. After the temperature sensor monitors the internal temperature condition of the precise lower digestive tract pathological specimen collector in real time, it will transmit the corresponding temperature data to the control system. Relevant modules in the control system (such as the threshold judgment and analysis unit in the data processing and analysis module, etc.) will compare and analyze this temperature data with the preset suitable temperature range for specimen preservation. If the comparison result shows that the current temperature exceeds the suitable range, for example, too high temperature may affect the cell activity of the specimen, or too low temperature has the risk of damaging the specimen, the control system will generate a corresponding regulation instruction and send it to the temperature regulation control unit.

[0102] The humidity regulation control unit also has a close communication link with the control system and the humidity sensor. The humidity sensor constantly monitors the humidity condition of the air inside the specimen collector and transmits the humidity data to the control system. The control system will compare the received humidity data with the preset suitable humidity range. When it is found that the humidity data deviates from this suitable range, for example, too high humidity is likely to cause specimen mildew, or too low humidity may cause specimen drying and dehydration, the control system will send a corresponding regulation instruction to the humidity regulation control unit.

[0103] The specimen processing prompt control unit is connected to the control system and simultaneously receives data transmitted from various sensors (such as a liquid level sensor, a photoelectric sensor, etc., sensors for detecting the situation of specimen placement). The control system will make a comprehensive judgment based on these sensor data. For example, when the liquid level sensor monitors that the liquid level in the liquid cavity 22 is approaching the upper limit, it means that the liquid volume is about to reach the accommodation limit. If not processed in time, there may be a situation where the liquid overflows and contaminates the specimen and other components of the collector; or when the photoelectric sensor detects that a specimen is placed in the collection box, in order to ensure the standard and orderly progress of subsequent specimen collection, recording and other processes.

[0104] The communication and external interaction module includes:

[0105] A data transmission interface unit, which is responsible for transmitting information such as specimen-related data and device operating status recorded inside the precise lower digestive tract pathological specimen collector to external devices by means of common communication methods such as USB, Bluetooth, and Wi-Fi;

[0106] A remote control unit, which is used to establish a connection channel with an external interaction module through communication. On the premise of having corresponding permissions and a security authentication mechanism, it enables users such as medical staff to remotely send control instructions to the precise lower digestive tract pathological specimen collector through external devices.

[0107] Specifically, the data transmission interface unit is connected to various relevant data storage and processing modules (such as the status recording and data analysis module, etc.) inside the precise lower digestive tract pathological specimen collector, and corresponding external interfaces are reserved. It has built-in communication protocol stacks and hardware circuits adapted to common communication methods such as USB, Bluetooth, and Wi-Fi.

[0108] When it is necessary to transmit specimen-related data recorded inside the collector (such as specimen collection time, source information, and specimen preservation environment data monitored by various sensors, etc.) and device operating status (such as working parameters of each component, whether there are fault prompts, etc.) to external devices (such as the hospital's pathological information management system, mobile devices of medical staff, etc.), corresponding configurations will be made first according to the communication methods supported by the external devices.

[0109] Based on the connection channel established by the remote control unit with the external interaction module through communication, it works relying on network communication technology and a security protection mechanism. On the one hand, it establishes a server function at the collector end or follows a specific network service protocol, and provides corresponding interfaces externally to receive external control instructions; on the other hand, a supporting control application program is installed on external devices (such as smartphones and tablets of medical staff). When this program communicates with the collector end, it needs to perform permission verification and security authentication operations first. After receiving the instruction, the remote control unit at the collector end will parse the instruction, verify its legality and effectiveness, and after confirming that it is correct, pass the instruction to the corresponding internal execution module (such as each unit in the execution control module), so as to drive the collector to perform corresponding functional operations.

[0110] Through the operation of the data transmission interface unit, data sharing and intercommunication between the inside and outside devices of the precise lower digestive tract pathological specimen collector are realized. The relevant management departments of the hospital can timely obtain various data of the specimen collector through the pathological information management system, which is convenient for comprehensively supervising the specimen collection work and subsequent data analysis and statistics, and helps to optimize the specimen collection process and improve work efficiency; medical staff can view the detailed information of the specimen and the operating status of the collector at any time through the mobile device, which is convenient for them to make corresponding preparations in advance and timely process and track the specimen, ensuring the smooth progress of the specimen collection and preservation work. It solves the problem of the deficiency of the traditional lower digestive tract pathological specimen collection device in data interaction and remote control.

The scope of the present invention is defined by the appended claims and their equivalents.
