Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an intestinal flora detection device with a structure for preventing cross contamination. Background Art

[0002] In the field of intestinal flora testing, the use and storage of collection swabs are key links to ensure the accuracy and reliability of test results. In the traditional intestinal flora testing process, the collection swabs are usually manually removed from the storage container by the user and then manually broken or discarded after the sample collection is completed. This method has several potential problems:

[0003] Complicated operation: Manually taking and breaking the collection swab requires the user to perform multiple hand operations, which increases the complexity and time cost of the operation.

[0004] High risk of cross-contamination: During manual operation, the collection swab is easily exposed to external contaminants. This is especially true in environments such as medical institutions or scientific research laboratories, where the risk of cross-contamination increases significantly due to the diversity and complexity of samples. In addition, if the used collection swab is not properly handled, it may also become a source of contamination.

[0005] Improper storage: Some existing intestinal flora testing devices lack dedicated storage modules, leading to used swabs being easily discarded or placed in inappropriate locations. This not only increases the risk of cross-contamination but also violates environmental protection principles. Furthermore, improper storage can damage the swabs, affecting the accuracy of subsequent test results.

[0006] To address these issues, the present invention proposes a device for detecting intestinal flora with a cross-contamination prevention mechanism. Through its innovative design, this device aims to facilitate the access and storage of collection swabs while effectively preventing cross-contamination and improving the hygiene and accuracy of the detection process. By employing an automated mechanical structure and a rational storage design, the present invention aims to overcome the shortcomings of traditional intestinal flora detection devices, providing users with a safer and more environmentally friendly detection tool. Summary of the Invention

[0007] To solve the above problems, the present invention provides an intestinal flora detection device with a structure for preventing cross-contamination. Through the ingenious design of the sample storage component and the pushing component, the present invention realizes the automatic retrieval and storage of the collection swab, which is not only simple and quick to operate, but also effectively prevents the occurrence of cross-contamination.

[0008] To achieve the above-mentioned object, the technical solution of the present invention is as follows: an intestinal flora detection device with a structure for preventing cross-contamination includes a collection module, the collection module includes a housing, and a storage module for storing used collection swabs is detachably connected to the bottom of the housing;

[0009] The shell is a hollow structure, and a sample storage component and a pushing component are installed in the shell. The sample storage component includes a sample storage plate, a sample storage groove is provided at the bottom of the sample storage plate, a collection swab is placed in the sample storage groove, a connecting rod is fixedly connected to the back of the sample storage plate, a cam is sleeved on the connecting rod, a button is sleeved on the end of the cam away from the connecting rod, and a serration is provided on one end of the button. A through groove is provided on the side wall of the shell, and a plurality of guide rails are provided on the side wall of the through groove, and one end of the guide rail is fixedly connected with an oblique tooth, and a plurality of slot keys that are slidably matched with the guide rail are fixedly connected to the side wall of the button. The outer side wall of the cam is fixedly connected with a convex strip that is slidably matched with the guide rail, and the convex strips are engaged with the oblique teeth and the serrations. A first spring is sleeved on the connecting rod, and a fixing ring is provided in the through groove;

[0010] The pushing assembly includes a push rod, a circular hole is opened on the top of the shell, the push rod and the circular hole are slidably matched, a fixed groove is fixedly connected to the bottom of the push rod, and a limiting assembly is fixedly connected to the push rod. The limiting assembly includes a limiting block, and a plurality of limiting grooves matching the limiting blocks are opened on the sample storage plate.

[0011] The technical principle of the above scheme is as follows: the intestinal flora detection device of the present invention mainly includes a collection module, in which a sample storage component and a pushing component are cleverly designed in the shell of the collection module to achieve safe and convenient use of the collection swab, while effectively preventing cross contamination.

[0012] The sample storage plate serves as a platform for storing collection swabs, and the sample storage slot at its bottom is used to place collection swabs. The cam is mounted on the connecting rod and is connected to the button to achieve transmission. The serrations on one end of the button cooperate with the beveled teeth on the guide rail on the side wall of the shell, while the slot key on the side wall of the button slides with the guide rail to ensure that the button slides stably on the guide rail. The ridges on the outer wall of the cam engage with both the beveled teeth and the serrations. When the button is pressed, the cam is driven to rotate through the engagement of the serrations with the beveled teeth and the engagement of the ridges with the serrations. The first spring provides a reset force for the button to ensure that the sample storage plate can return to its initial position after the button is released.

[0013] The push rod slides into the circular hole at the top of the housing, pushing the swab onto the sample reservoir for sample collection. A stopper is fixed to the push rod, while a stopper slot is defined in the sample reservoir. When the push rod descends to a certain position, the stopper snaps into the stopper slot, securing the push rod relative to the sample reservoir and ensuring the stability of the swab during the collection process.

[0014] The above scheme has the following beneficial effects:

[0015] 1. This solution, through the provision of a sample storage component and a pusher component, enables convenient access and storage of collection swabs, avoiding the cross-contamination issues that may result from traditional manual handling. Compared to the contamination risks associated with manual handling of collection swabs in existing technologies, this solution achieves automated handling of collection swabs through a mechanical structure, improving the hygiene and accuracy of the testing process.

[0016] 2. This solution utilizes a cam, button, ridges, beveled teeth, and serrations to automatically eject and reposition the collection swab. With a simple press of a button, the swab ejects from the sample reservoir, facilitating intestinal sample collection. Once the collection is complete, release the button, and the spring automatically resets the swab, ready for the next use. Compared to the cumbersome manual insertion and removal of the swab in existing technologies, this solution is much simpler and faster.

[0017] 3. This solution ensures the stability of the collection swab during storage and transport through the design of a stopper assembly. The matching structure of the stopper block and the stopper groove effectively prevents the collection swab from shaking within the housing, avoiding damage or contamination caused by shaking. Compared with the shortcomings of existing swabs that are easily damaged or contaminated by shaking, this design significantly improves the service life of the collection swab and the reliability of the test results.

[0018] 4. This solution, through the provision of a storage module, can facilitate users to store used collection swabs, avoiding the risk of cross-contamination caused by random discarding. Compared with the lack of an effective storage mechanism in the prior art, this enhances the practicality and environmental friendliness of the device.

[0019] Furthermore, the storage module includes an outer shell, which is a cylindrical structure. The outer shell is detachably connected to the end of the shell away from the circular hole. Both ends of the outer shell are detachably connected to a cover body, and a cutting assembly is installed inside the shell.

[0020] Beneficial effects: The storage module includes an outer shell, which is designed as a cylindrical structure, which is not only convenient for storage and carrying, but also can effectively protect the collection swabs stored inside from external contamination. The outer shell and the shell body are detachably connected at the end away from the circular hole. This design allows the storage module to be easily separated or combined with the collection module, which is convenient for users to operate according to actual needs. Both ends of the outer shell are detachably connected with a cover body. This design further enhances the sealing and protection of the storage module. The presence of the cover body can prevent external dust, bacteria and other pollutants from entering the interior of the outer shell, thereby ensuring the cleanliness and safety of the collection swab during storage. At the same time, the detachability of the cover body also makes it easy for users to open or close the outer shell when needed.

[0021] Furthermore, the cutting assembly includes a first blade, which is fixedly connected to the inner wall of the shell. A second blade is hinged to one side of the first blade. A sliding groove matching the second blade is provided on the shell, and the second blade slides in cooperation with the sliding groove at one end away from the first blade.

[0022] Beneficial Effects: The excision assembly includes a first blade fixedly attached to the inner sidewall of the housing and a second blade hingedly connected to the first blade. This design allows the second blade to rotate or move relative to the first blade, effectively cutting or processing the collection swab, eliminating the risk of contamination and injury associated with manual excision. A matching groove on the housing guides and limits the second blade's movement, ensuring stability and accuracy during the excision process and reducing the risk of cross-contamination.

[0023] Furthermore, a second spring is provided between the second blade and the slide groove, one end of the second spring is fixedly connected to the second blade, and the other end of the second spring is fixedly connected to the inner wall of the slide groove. The second spring is used to automatically reset the second blade after the second blade completes the cutting action.

[0024] Benefits: A second spring, added between the second blade and the chute, provides an automatic reset function for the cutting assembly. This design allows the second blade to automatically return to its initial position after completing a cut, without manual intervention, ready for the next cut. This automatic reset ensures that the cutting assembly returns to its initial position after each cut, maintaining the stability and reliability of the device and helping to reduce malfunctions and damage caused by improper operation or errors.

[0025] Furthermore, both the side walls of the shell and the top wall of the cover are provided with transparent observation windows, which are used to observe the status of the collection swab. The observation windows are made of transparent and wear-resistant material.

[0026] Beneficial Effects: Through the transparent observation window, users can observe the number, location, and contamination status of the collection swabs at any time, helping to promptly identify and address potential problems and ensure the quality and safety of the collection swabs. The addition of a transparent observation window allows users to understand the internal conditions without opening the storage module, thereby simplifying the operation process and helping to improve the ease of use and convenience of the device, especially in emergency situations or when the status of the collection swab needs to be quickly determined. The observation window is made of a transparent and wear-resistant material, ensuring its stability and reliability for long-term use. This material is resistant to scratches, wear, and contamination, thereby extending the service life of the observation window and maintaining the neatness and aesthetics of the device.

[0027] Furthermore, sealing components are installed at the connection between the shell and the outer shell and at the connection between the outer shell and the cover body. The sealing components include but are not limited to elastic sealing rings and sealing gaskets.

[0028] Beneficial Effects: Installing sealing components, such as elastic sealing rings and gaskets, at key connection points is crucial for ensuring a clean environment within the intestinal flora testing device and preventing external contamination. This design not only enhances the device's sealing performance but also improves its overall performance and user experience in multiple ways. The sealing components effectively prevent external contaminants such as dust, bacteria, and moisture from entering the device, thereby protecting the collection swab from contamination and ensuring the accuracy of test results, which is crucial for maintaining high standards for intestinal flora testing.

[0029] Furthermore, a monitoring component is installed on the side wall of the acquisition module, which includes a temperature sensor. The temperature sensor signal is connected to a controller, and the controller is used to transmit the temperature data monitored in real time by the temperature sensor to the smart device of the medical staff.

[0030] Beneficial effects: The temperature sensor can monitor the temperature inside the collection module in real time to ensure that the samples are stored under appropriate conditions. Once the temperature exceeds the preset range, the controller immediately triggers an early warning and notifies medical staff through smart devices. This instant feedback mechanism helps to respond quickly and prevent samples from being damaged or deteriorating due to improper temperature. Precise control of sample storage temperature is key to ensuring the accuracy of test results. Through the synergy of temperature sensors and controllers, it can be ensured that samples are stored under optimal temperature conditions, thereby improving sample quality and the reliability of test results. The controller can record historical data from the temperature sensor for subsequent analysis by medical staff, which helps to understand temperature changes during sample storage and provide a scientific basis for optimizing storage conditions and improving test accuracy.

[0031] Furthermore, it also includes an early warning module, which includes an indicator light and a buzzer. The indicator light is used to flash and emit light of different colors to indicate different early warning reminders, and the buzzer is used to emit different alarm sounds. The indicator light and the buzzer are both connected to the controller signal. When the controller determines that the real-time temperature data exceeds the preset threshold, the early warning module emits an audible and visual alarm signal.

[0032] Beneficial effects: When the controller detects that the real-time temperature data exceeds the preset threshold, the early warning module immediately issues an audible and visual alarm signal. This instant feedback mechanism can quickly attract the attention of medical staff, allowing them to take immediate measures to prevent samples from being damaged or deteriorating due to abnormal temperatures. The indicator light flashes and emits different colors of light to indicate different early warning reminders. This visual and intuitive representation helps medical staff quickly understand the alarm information. At the same time, the different alarm sounds emitted by the buzzer also facilitate auditory recognition. This combination of audio and video alarm method reduces the false alarm rate and improves the accuracy of the alarm. The addition of the early warning module enables the device to automatically alarm when the temperature is abnormal, thereby avoiding potential risks caused by insufficient manual monitoring. This enhances the reliability and safety of the device and ensures the quality and safety of samples during collection, storage and transportation.

[0033] Furthermore, the shell, the push rod and the outer side wall of the outer shell are all provided with anti-slip textures, which are used to increase the friction when the medical staff holds it.

[0034] Beneficial Effects: The anti-slip texture significantly increases friction when medical staff grip the device, preventing accidental dropout or operational errors due to slippage, and helping to ensure the safety and stability of the device during collection, storage, and transportation. The anti-slip texture design makes it easier for medical staff to grip the device during operation, maintaining a good grip even in wet or greasy environments, helping to improve work efficiency and reduce delays caused by operational inconvenience. The anti-slip texture not only increases friction but also reduces wear and scratches on the device casing to a certain extent, helping to extend the device's lifespan and reduce maintenance costs.

[0035] Furthermore, an intelligent identification component is installed on the side wall of the shell. The intelligent identification component includes a QR code label to ensure that the usage status, replacement time and operator information of the collection swab can be tracked and recorded after each use.

[0036] Benefits: The QR code labels enable the rapid recording and tracking of swab usage status, replacement time, and operator information. This significantly simplifies the traditional manual recording process, improves management efficiency, and allows medical staff to focus more on the testing process itself. By scanning the QR code label, relevant information is automatically recorded, avoiding errors and omissions that may occur in manual recording. This ensures data accuracy and provides a reliable foundation for subsequent data analysis and quality control.

[0047] The following is further described in detail through specific implementation methods:

[0048] Example 1:

[0049] As attached Figures 1 to 5 As shown: A device for detecting intestinal flora with a structure for preventing cross-contamination includes a collection module, which includes a shell 1, a circular hole 101 is opened on the top of the shell 1, and a storage module for storing used collection swabs 4 is detachably connected to the bottom of the shell 1 through a thread; the storage module includes an outer shell 13, and the outer shell 13 is a cylindrical structure. The outer shell 13 is detachably connected to the end of the shell 1 away from the circular hole 101, and both ends of the outer shell 13 are detachably connected to a cover.

[0050] The shell 1 is a hollow structure, and a sample storage component and a pushing component are installed in the shell 1. The sample storage component includes a sample storage plate 2, a sample storage slot 3 is provided at the bottom of the sample storage plate 2, a collection swab 4 is placed in the sample storage slot 3, a connecting rod 5 is fixedly connected to the back of the sample storage plate 2, a cam 6 is sleeved on the connecting rod 5, a button 7 is sleeved on the end of the cam 6 away from the connecting rod 5, and a serration 701 is provided on one end of the button 7. A through slot 8 is provided on the side wall of the shell 1, and a number of guide rails 801 are provided on the side wall of the through slot 8, and one end of the guide rail 801 is fixedly connected to a bevel tooth 802, and a number of slot keys 702 that slide with the guide rail 801 are fixedly connected to the side wall of the button 7, and a convex strip 601 that slides with the guide rail 801 is fixedly connected to the outer wall of the cam 6, and the convex strip 601 can engage with the bevel tooth 802 and the serration 701. A first spring 9 is sleeved on the connecting rod 5, and a fixing ring is provided in the through slot 8.

[0051] The pushing assembly includes a push rod 10, which slides with the circular hole 101 on the top of the shell 1. A fixing groove 11 is welded and fixed to the bottom of the push rod 10. A limiting assembly is fixedly connected to the push rod 10. The limiting assembly includes a limiting block 12. The sample storage plate 2 is provided with several limiting grooves 201 that match the limiting block 12.

[0052] A cutting assembly is mounted within the housing 1 and includes a first blade 14, which is adhesively fixedly attached to the inner wall of the housing 1. A second blade 15 is hingedly connected to one side of the first blade 14. A slot is defined in the housing 1 to mate with the second blade 15, and the end of the second blade 15, distal from the first blade 14, slides in engagement with the slot. A second spring 16 is disposed between the second blade 15 and the slot. One end of the second spring 16 is fixedly attached to the second blade 15, while the other end is fixedly attached to the inner wall of the slot. The second spring 16 is configured to automatically reset the second blade 15 after the second blade 15 completes its cutting action.

[0053] Transparent observation windows are provided on the side walls of the housing 1 and the top wall of the cover. These windows are used to observe the status of the collection swab 4 and are made of a transparent, wear-resistant material. Sealing assemblies are installed at the connection between the housing 1 and the outer shell 13, and at the connection between the outer shell 13 and the cover. These sealing assemblies include, but are not limited to, elastic sealing rings and gaskets. The installation of these sealing assemblies effectively prevents the ingress of external contaminants and improves the hygiene of the sampling process. The outer walls of the housing 1, push rod 10, and outer shell 13 are all provided with anti-slip textures to increase friction when gripped by medical personnel.

[0054] The specific implementation process is as follows: During the preparation phase, first ensure that all components (including the housing 1, sample storage plate 2, connecting rod 5, cam 6, button 7, push rod 10, stop assembly, cutting assembly, outer shell 13, and cover) are rigorously cleaned and disinfected to eliminate potential sources of contamination. At the same time, check the connections between components for firmness, especially threaded connections, to ensure they will not loosen or leak during collection and storage.

[0055] When it is necessary to collect samples from the patient, the button 7 is pressed, and the key 702 of the button 7 and the serration 701 on the cam 6 slide along the guide rail 801. When the ridge 601 on the cam 6 is free from the restriction of the guide rail 801, the ridge 601 of the cam 6 will slide to the bottom of the serration 701 at the end of the button 7 under the action of the first spring 9. At the same time, the connecting rod 5 pushes out the sample storage plate 2, and the collection swab 4 in the sample storage tank 3 will be pushed into the fixed groove 11. After releasing the button 7, the button 7 and the cam 6 will reset under the action of the first spring 9. At this time, the ridge 601 of the cam 6 will gradually approach the beveled teeth 802 on the edge of the guide rail 801, and start to rotate under the action of the beveled teeth 802, and fall off the restriction of the serration 701 at the end of the button 7, and finally slide to the bottom of the beveled teeth 802 on the edge of the guide rail 801, and the cam 6 is forced to stop moving.

[0056] The push rod 10 is then pushed, pushing the collection swab 4 in the retaining groove 11 out of the housing 13 at the bottom of the housing 1. Depending on the patient's specific situation (i.e., whether the patient is a child or an adult), the stopper 12 is fixed in a different retaining groove 201, allowing the collection swab 4 to extend to different lengths (approximately 4-5 cm for adults and approximately 2-3 cm for children). During this process, medical personnel can observe the status of the collection swab 4 through the transparent observation window to ensure that the swab has been successfully extended and reached the appropriate collection position. Medical personnel use the collection swab 4 to collect a mucus or fecal sample from the patient's rectal surface. After the collection is completed, press the button 7 again, the convex strip 601 on the cam 6 will break away from the restriction of the guide rail 801 again, and get stuck on the serration 701 at the end of the button 7 again. Following the button 7, the slot key 702 of the button 7 and the serration 701 on the cam 6 return to the highest point along the guide rail 801. At this time, the collection swab 4 can be retracted into the inside of the shell 1, and then the cover of the shell 13 away from the end of the shell 1 is closed to ensure that the collection swab 4 is safely enclosed in the shell 13.

[0057] Then remove the outer shell 13 to proceed to the sample separation stage. The medical staff first confirms that the threaded connection between the outer shell 13 and the housing 1 has been loosened, and then gently rotates the outer shell 13 to remove it. During this process, the outer shell 13 will drive the second blade 15 in the slide to rotate together. When the second blade 15 rotates to a position in contact with the first blade 14, the two will cut each other, completing the cutting of the head of the collection swab 4 and the separation of the sample. At this time, the second spring 16 will automatically reset the second blade 15 to ensure that the cutting assembly is in the initial state. After the head of the collection swab 4 falls into the outer shell 13, the medical staff closes the cover at the other end of the outer shell 13 to ensure that the sample is safely enclosed in the outer shell 13 with the cover closed at both ends. This design ensures that the sample will not come into contact with the external environment after collection, thereby effectively preventing the risk of cross contamination.

[0058] Next, medical personnel transport the sample-containing housing 13 to the laboratory for further analysis. In the laboratory, technicians can open the cover and easily remove the cut head of the collection swab 4 for intestinal flora testing. Because the entire collection and storage process is carried out in a closed environment, the accuracy and reliability of the test results are greatly improved.

[0059] Example 2:

[0060] The difference from Example 1 is that a monitoring component is installed on the side wall of the acquisition module, and the monitoring component includes a temperature sensor. The temperature sensor signal is connected to a controller, and the controller is used to transmit the temperature data monitored in real time by the temperature sensor to the medical staff's smart device (such as a mobile phone, tablet or computer).

[0061] The system also includes a warning module, which includes an indicator light and a buzzer. The indicator light flashes and emits different colors to indicate different warning alerts, while the buzzer emits different alarm sounds. Both the indicator light and the buzzer are connected to the controller signal. When the controller determines that the real-time temperature data exceeds the preset threshold, the warning module issues an audible and visual alarm signal. For example, when the temperature is slightly high but still within the acceptable range (users can set this according to actual needs), the indicator light may emit a yellow light and flash slowly; when the temperature exceeds the preset threshold, the indicator light emits a red light and flashes rapidly. A gentle alarm sound indicates that the temperature is approaching the threshold, while a loud alarm sound indicates that the temperature has exceeded the threshold.

[0062] The specific implementation process is as follows: During sample storage, the temperature sensor continuously monitors the temperature changes inside the shell 1 or the sample storage environment, and transmits real-time data to the controller. The controller receives and processes the temperature data, and sends it to the smart device of the medical staff. The medical staff can view the temperature data in real time through the application on the smart device to understand the temperature conditions of the sample storage environment. When the real-time temperature data exceeds the preset threshold, the controller immediately triggers the early warning module. The indicator light starts to flash and emit different colors of light, and the buzzer also emits a corresponding alarm sound. After hearing the alarm and seeing the indicator light flashing, the medical staff can quickly understand the possible problems in the sample storage environment and take appropriate measures to deal with them.

[0063] Medical staff, following the early warning module's prompts, check the sample storage environment for abnormalities (such as excessively high, low, or unstable temperatures). If any abnormalities are detected, they should immediately take corrective measures, such as adjusting the sample storage temperature or replacing the sample storage container. Medical staff can also record abnormalities and handling measures through the app on their smart devices for subsequent analysis and improvement.

[0064] Example 3:

[0065] The difference from Example 2 is that an intelligent identification component is installed on the side wall of the shell 13, and the intelligent identification component includes a QR code label for ensuring that the usage status, replacement time and operator information of the collection swab 4 can be tracked and recorded after each use.

[0066] The specific implementation process is as follows: Before using the intestinal flora detection device for the first time, ensure that the QR code label is correctly installed on the side wall of the housing 13. The medical staff uses a smart device to scan the QR code label, enter the information system, and enter the initial status of the collection swab 4, the recommended replacement time, and their own identity information as operator information. The sample is collected according to the previous steps, ensuring that the collection swab 4 remains clean and sterile during use. After the collection is completed, the medical staff uses the smart device to scan the QR code label again, updating the use status of the collection swab 4 to "used."

[0067] When the collection swab 4 reaches the recommended replacement time or needs to be replaced for other reasons, the medical staff first uses a smart device to scan the QR code label. Enter the information of the new collection swab 4 into the information system, including the unique identifier, initial status, recommended replacement time, and their own identity information as operator information. Then, remove the old collection swab 4 from the device and dispose of it according to the medical waste disposal process. Install the new collection swab 4 into the device and prepare for the next sample collection. The information system regularly collects and analyzes the usage data of the collection swab 4, including the number of uses, replacement frequency, operator information, etc. Based on the data analysis results, potential improvement points can be identified, such as optimizing the replacement strategy of the collection swab 4, improving the operational efficiency of medical staff, etc. Medical staff and managers can formulate corresponding improvement measures based on the analysis results and continuously monitor their effects.

[0068] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
