Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological detection technology, and in particular to a biological detection device. Background Technology
[0002] Bioaerosols are colloids formed by the interaction of various biological components with gases and particles in the air. They include liquid and solid components suspended in the air, such as microorganisms, microbial metabolites, and biotoxins. Because airborne bioaerosols can be transported over long distances, they can easily become a medium for the spread of epidemic pathogens; therefore, the detection of airborne aerosols is essential.
[0003] In related technologies, separate devices are set up for collecting and detecting bioaerosols. During the detection process, one device is used to collect the bioaerosols, and then another device is used to detect the specimen formed by the collected bioaerosols. To avoid interference between the collection and detection processes, the collection and detection devices are usually set up in two separate operating areas. However, the separate sampling and detection devices not only increase costs, but also affect the continuity and convenience of sampling and detection. Utility Model Content

[0039] This invention proposes a biological detection device.
[0040] Please refer to Figure 1 and Figure 7 In one embodiment of this utility model, the biological detection device includes:
[0041] Device body 100;
[0042] Sampling component 200 is disposed on device body 100, and sampling part 210 of sampling component 200 is exposed outside device body 100 to form test piece 400;
[0043] Detection component 300 is disposed on the device body 100 and is used to detect the object to be tested 400; and
[0044] The device body 100 is used to identify the item to be tested 400 and to generate a test result based on the test data from the test component 300.
[0045] The technical solution of this utility model integrates the sampling component 200 and the detection component 300 into the same device body 100, realizing an integrated design for bioaerosol collection and detection. This effectively solves the problems of low efficiency, easy contamination during sample transfer, high system cost, and large space occupation caused by the independent collection and detection devices in the prior art. The sampling component 200 is set in the device body 100, and its sampling part 210 is exposed outside the device body 100, which can directly collect bioaerosols in the air to form a test sample 400. Subsequently, the test sample 400 can be detected manually or through the device body 100 by the detection component 300 set in the same device body 100, improving the timeliness and convenience of the operation from sampling to detection. The device body 100 has the function of identifying the object to be tested 400 and can automatically generate test results based on the test data output by the detection component 300. This ensures that the object to be tested 400 detected by the detection component 300 is recorded before being tested, and then the test results of the detection component 300 are used for matching, thereby ensuring the reliability of the output test results. In this way, the multi-area operation process required by traditional separate detection and sampling devices is simplified, the threshold for use and maintenance costs are reduced, and the environmental adaptability and portability of the device are enhanced. This allows the device to be flexibly deployed in various scenarios such as hospitals, airports, and laboratories, providing reliable support for rapid response to the spread of pathogenic microorganisms and improving public health safety monitoring capabilities.
[0046] It should be noted that the test piece 400 can be automatically generated on the sampling unit 210, or it can be collected within the sampling unit 210, or the sampling unit 210 itself can become the test piece 400. Subsequently, the test piece 400 is automatically or manually transferred to the detection assembly 300 for detection. For example, the test piece 400 can be manually removed from the sampling assembly 200 and placed in the detection assembly 300 for detection; or the sampling assembly 200 can transport the test piece 400 to the detection assembly 300 through a pump or pipeline within the device body 100. After the sampling component 200 completes sampling, the control module inside the device body 100 is activated to automatically transport the test piece 400 to the detection component 300 for detection. Alternatively, the test piece 400 can be generated externally by reacting the bioaerosols collected by the sampling unit 210 with sampling tubes, sampling cotton, etc. The test piece 400 generated from the reaction of the sampling tubes, sampling cotton, etc., and the bioaerosols collected by the sampling unit 210 is then placed manually or automatically by external equipment into the detection component 300 for detection. It can be understood that before the detection component 300 detects the test piece 400, the device body 100 first identifies the test piece 400, and then the detection component 300 can detect the test piece to generate detection data. The device body 100 then generates the detection result based on the detection data and by matching it with the identified test piece 400.
[0047] The device body 100 includes a display mechanism 180, a scanning module 120, a printing module 130, a control module, and a heat dissipation module. In operation, each item 400 to be tested has a unique QR code or barcode label. This label is scanned and stored on the scanning module 120, and then transferred to the testing component 300 for testing. After the test results are obtained, the operator can operate the printing module 130 through the display interface of the display mechanism 180 to print the corresponding test results. For manual transfer of the item 400 to the testing component 300, the scanning module 120 uses a scanning head exposed on the device body 100 to scan the item 400. For automatic transfer of the item 400 to the testing component 300 via internal pipes or pumps within the device body 100, the scanning module 120 also has scanning heads on the pipes and pumps to scan the item 400. During this process, the control module coordinates the operation of each different module, the heat dissipation module dissipates the heat generated by each module during operation, and the display mechanism 180 displays the detection process.
[0048] In one embodiment, please refer to Figure 1 and Figure 7The sampling component 200 and the detection component 300 are respectively disposed at opposite ends of the device body 100 along the first direction. This layout fully considers the rationality of functional zoning and operational procedures in its structural design. By placing the sampling component 200 at one end of the device body 100 and exposing the sampling section 210 to directly contact bioaerosols in the air, efficient capture of target substances is achieved. The detection component 300 is disposed at the other end of the device body 100. This reduces mutual interference between the detection component 300 and the sampling component 200, and also creates a force balance on the device body 100 along the first direction, facilitating the placement of the biological detection device. Furthermore, this layout of the detection component 300 and the sampling component 200 ensures the continuity of sampling and detection operations while providing ample space for the device body 100. This facilitates the installation and arrangement of various modules within the device body 100, reducing the device's size and enhancing its portability and field applicability. It is particularly suitable for mobile monitoring scenarios requiring rapid deployment and efficient detection. For example, Figure 1 and Figure 2 As shown, the first direction is configured as the length direction of the biological detection device.
[0049] In one embodiment, please refer to Figure 1 and Figure 7 The device body 100 is provided with an exhaust port 110, the sampling component 200 is provided with an air inlet 213, and the sampling part 210 is located in the channel 321 that connects the air inlet 213 and the exhaust port 110. The air inlet 213 and the exhaust port 110 are arranged opposite to each other along the second direction. It should be noted that an air pump 170 is installed inside the device body 100. The air pump 170 draws external air sequentially through the air inlet 213, the sampling section 210, and the exhaust port 110, thereby promoting the collection of bioaerosols from the air by the sampling section 210. The air inlet 213 and the exhaust port 110 are arranged opposite each other along a second direction, which helps to form a uniform airflow field and avoids uneven sampling caused by local eddies or dead zones. At the same time, this airflow layout helps to reduce the repeated adsorption of air from the exhaust port 110 back to the air inlet 213, improving the sampling efficiency and reliability of the sampling section 210. This not only enhances the device's ability to collect bioaerosols from the air but also provides a reliable sample basis for the efficient analysis of the subsequent detection component 300, further improving the practicality of the equipment operation. For example, Figure 1 and Figure 2 As shown, the second direction is configured as the width or thickness direction of the biological detection device, and intersects the first direction as if it were perpendicular to it.
[0050] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 8The sampling assembly 200 includes a sampling section 210 and a transmission body 230. The device body 100 is equipped with an air pump 170. The transmission body 230 is connected to and communicates with the air pump 170, and the sampling section 210 is detachably connected to the transmission body 230. It can be understood that by connecting the transmission body 230 to the air pump 170 on the device body 100, stable control of the airflow path is achieved, enabling efficient intake of bioaerosols in the air and capture by the sampling section 210. The detachable connection of the sampling section 210 to the transmission body 230 facilitates the replacement of the sampling section 210 with different types of sampling media to adapt to diverse testing needs, and also helps avoid cross-contamination, improving the accuracy and repeatability of the test results. Thus, the detachable sampling section 210 not only enhances the flexibility and applicability of the system but also simplifies the maintenance and cleaning process, improving the overall ease of use and operational efficiency of the equipment, making it suitable for rapid on-site testing tasks in multiple scenarios and at high frequency.
[0051] Furthermore, in this embodiment, please continue to refer to... Figure 3 , Figure 4 and Figure 8 The sampling assembly 200 also includes a first locking member 220. The sampling unit 210 includes an air inlet valve 212 and a collection head 211. The air inlet valve 212 is provided with an air inlet 213. The collection head 211 is sealed to the air inlet valve 212 by a first sealing ring 214 and communicates with the air inlet 213. The end of the air inlet valve 212 away from the collection head 211 is sealed to the transmission body 230 by the first locking member 220. The collection head 211 is connected to the transmission body 230 through the air inlet valve 212. The connection between the collection head 211 and the air inlet valve 212 is provided with a first sealing ring 214, which can be one or more. The first sealing ring 214 can seal the connection between the two in the circumferential or axial direction, which solves the problems of poor sealing, unstable connection and easy leakage in the traditional bioaerosol collection process, resulting in low sampling efficiency, sample contamination or loss. By setting a first sealing ring 214 between the collection head 211 and the air inlet valve 212, the airtightness of the sampling path is ensured, preventing aerosol leakage during transmission. Simultaneously, the air inlet valve 212 achieves a detachable yet reliable sealed connection with the transmission body 230 via a first locking element 220. This allows users to quickly replace different types of sampling units 210 to adapt to diverse detection needs while ensuring stable air transmission. This connection method, combining high sealing performance and modularity, not only improves the overall device's efficiency in collecting bioaerosols and sample integrity but also enhances the safety and convenience of equipment operation, making it suitable for airborne microbial monitoring scenarios with high requirements for detection accuracy and on-site adaptability. It should be noted that the sealed connection referred to in this embodiment, and as referred to below, means that the joint between the two is tightly abutted to prevent leakage from the connecting channel 321.
[0052] The first locking member 220 is equipped with a third sealing ring 221. While the first locking member 220 connects the intake valve 212 and the transmission body 230 through screwing, snap-fitting, or plugging, the third sealing ring 221 is also clamped at the abutment between the intake valve 212 and the transmission body 230. The third sealing ring 221 can be clamped between the intake valve 212 and the transmission body 230 in the locking direction of the first locking member 220, such as when the first locking member 220 is configured as a nut. One end of the intake valve 212 connected to the transmission body 230 is threaded. The transmission body 230 is inserted into the intake valve 212. The third sealing ring 221 is arranged around the outer periphery of the transmission body 230 and is interference-fitted with the transmission body 230. The first locking member 220 clamps the third sealing ring 221 at the end of the intake valve 212. Alternatively, if the transmission body 230 is inserted into the intake valve 212, the third sealing ring 221 is clamped on the radially opposite sides of the transmission body 230 and the intake valve 212.
[0053] Without loss of generality, the intake valve 212 has a nested tube, and the channel 321 in the nested tube is connected to the transmission body 230 and the sampling head respectively. The intake port 213 is located in the outer channel 321 of the nested tube and is connected to the sampling head along the outer channel 321 of the nested tube. The sampling head is set in a conical shape in the direction away from the intake valve 212 and is placed vertically in an inverted cone shape. Air enters the outer channel 321 of the nested tube through the air inlet 213 and flows into the collection head 211. The collection head 211 contains a solution. When the collection head 211 is assembled with the air inlet valve 212, air enters through the air inlet 213 and is injected into the solution in the collection head 211 by the air inlet valve 212. The air then undergoes centrifugal motion in the collection head 211 to achieve uniform mixing with the solution in the collection head 211. The particulate matter in the air is dissolved into the solution to form a reagent solution. The remaining excess air, due to its relatively light mass, rises from the channel 321 in the nested tube to the transmission body 230, and then from the transmission body 230 to the air pump 170, and is then discharged from the exhaust port 110 by the air pump 170.
[0054] Regarding the connection method between the transmission body 230 and the device body 100, in one embodiment, please refer to... Figure 3 , Figure 4 and Figure 8The sampling assembly 200 also includes a second locking member 240. The transmission body 230 includes a connecting pipe 231 and a mounting part 232. The mounting part 232 is engaged with the device body 100 and is sealed to the air pump 170 by a second sealing ring 233. The connecting pipe 231 is sealed to the mounting part 232 by the second locking member 240. The other end of the connecting pipe 231 away from the mounting part 232 is connected to the sampling part 210. A second sealing ring 233 is provided at the connection between the connecting pipe 231 and the mounting part 232. One second sealing ring 233 or multiple second sealing rings 233 can be provided. The second sealing ring 233 can be provided circumferentially between the mounting part 232 and the inlet of the air pump 170, or at the axial contact point. This effectively solves the problems of gas leakage, reduced sampling efficiency, and unstable system operation caused by poor gas path connection in traditional bioaerosol collection. By securing the mounting part 232 to the device body 100 and placing a second sealing ring 233 between it and the air pump 170, the airtightness between the air pump 170 and the transmission body 230 is ensured. The connecting pipe 231 is detachably and sealed to the mounting part 232 via a second locking member 240. This not only enhances the overall structural robustness but also allows users to easily replace the transmission body 230 or sampling part 210 with different specifications as needed, improving the modularity and flexibility of the biological detection device. This sealing connection method comprehensively strengthens the stability and sealing effect of the sampling path, ensuring the integrity of bioaerosol collection and the accuracy of subsequent detection results. It is suitable for rapid on-site detection tasks with high airtightness requirements and complex operating environments.
[0055] The second locking member 240 is provided with a fourth sealing ring 241. While the second locking member 240 connects the connecting pipe 231 and the mounting part 232 via screwing, snap-fitting, or plugging, the fourth sealing ring 241 is also clamped at the abutment between the connecting pipe 231 and the mounting part 232. The fourth sealing ring 241 can be clamped between the connecting pipe 231 and the mounting part 232 in the locking direction of the second locking member 240, such as when the second locking member 240 is configured as a nut. The mounting part 232 is threaded at one end of the connecting pipe 231. The connecting pipe 231 is inserted into the mounting part 232. The fourth sealing ring 241 is arranged around the outer periphery of the connecting pipe 231 and is interference-fitted with the mounting part 232. The second locking member 240 clamps the fourth sealing ring 241 at the end of the mounting part 232. Alternatively, when the connecting pipe 231 is inserted into the mounting part 232, the fourth sealing ring 241 is clamped on the radially opposite sides of the connecting pipe 231 and the mounting part 232.
[0056] Without loss of generality, the lower part of the mounting part 232 is fixed to the device body 100 by means of screwing, snap-fitting, etc. The device body 100 is provided with an opening corresponding to the mounting part 232. A retaining ring is formed on the outer periphery of the mounting part 232, and the retaining ring is engaged with the opening of the device body 100 to limit and fix the mounting part 232 in the circumferential and axial directions, so as to ensure the stability of the connection between the two ends of the mounting part 232 and the connecting pipe 231 and the air pump 170, respectively. The lower end of the mounting part 232 is provided with an inner ring, and the outer periphery of the inner ring forms a limiting ring groove. The second sealing ring 233 is placed at the bottom of the limiting ring groove. The inlet pipe of the air pump 170 is inserted into the limiting ring groove, so as to clamp the second sealing ring 233 at the bottom of the limiting ring groove, thereby ensuring the connection and sealing of the mounting part 232 and the air pump 170.
[0057] Regarding the use of the detection component 300, in one embodiment, please refer to... Figure 5 , Figure 6 and Figure 9 The device body 100 is provided with a detection port 140, and the detection component 300 is disposed at the detection port 140. The detection port 140 is covered by a flip-up cover 150. A sensor 160 is provided on the device body 100 corresponding to the flip-up cover 150. The sensor 160 is used to detect the opening and closing of the detection port 140 by the flip-up cover 150. The device body 100 is used to control the operation of the detection component 300 based on the signal output by the sensor 160. It should be noted that the item to be detected 400 has two specifications, such as... Figure 6 As shown, in one specification, the component to be tested 400 is shorter, and the flip cover 150 is rotatably connected to the detection port 140 of the device body 100. The component to be tested 400 can be inserted into the detection port 140 for testing by the component to be tested 300. In another specification, the component to be tested 400 is longer, and one end of the component to be tested 400 is inserted into the detection port 140. The flip cover 150 is rotatably connected to the end of the component to be tested 400 away from the detection port 140 and can be opposite to the sensor 160, and the flipping state of the flip cover 150 is detected by the sensor 160.
[0058] It is understandable that the operation of the detection component 300 requires the sensor 160 to detect that the flip cover 150 has opened the detection port 140. The flip cover 150 opening the detection port 140 also indicates that the test piece 400 is not placed or is not properly placed in the detection component 300. At this time, the detection component 300 cannot operate. Once the sensor 160 detects that the flip cover 150 has closed the detection port 140, it also indicates that the test piece 400 is in the detection component 300 or has been removed. This allows the sensor 160 to control the operation or stop the operation of the detection component 300, thus solving the problem that traditional bioaerosol detection equipment lacks an automated linkage mechanism and is prone to detection failure or equipment damage due to misoperation. By integrating a sensor 160 onto the flip cover 150, the sealing status of the detection port 140 can be monitored in real time. The detection component 300 is automatically activated when the flip cover 150 is closed and a good seal is confirmed, ensuring the detection process takes place in a stable and safe environment. Simultaneously, this structure prevents accidental activation of the detection process when the flip cover 150 is not closed, thereby avoiding sample exposure or detection errors and improving the reliability of the detection results and the safety of equipment use. Furthermore, this mechanism of automatically triggering the detection process based on the flip cover 150's status further enhances the human-machine interface and intelligence level of the equipment, simplifies operation steps, and is suitable for quick use by various non-professionals, demonstrating strong practicality and adaptability to the field. It should be noted that the closing of the detection port 140 by the flip cover 150 also mutually distinguishes with the sampling component 200, reducing the impact of the sampling component 200's operation on the detection component 300.
[0059] In one embodiment, please refer to Figure 1 and Figure 7The biological detection device also includes a base plate (not shown in the figure), which is snapped onto the bottom of the device body 100 and has a fixing part for securing the biological detection device. It should be noted that the biological detection device needs to be positioned at a specific height. For different detection environments, the biological detection device is also paired with a triangular support frame. The base plate is snapped onto the bottom of the device body 100, and the fixing part on the base plate connects to the triangular support frame, effectively solving the problems of unstable placement, easy tipping, and inconvenient on-site installation that exist in traditional detection equipment during practical applications. By detachably snapping the base plate onto the bottom of the device body 100, not only is the overall structural stability and center of gravity balance of the device enhanced, but a physical support foundation is also provided for flexible deployment in different scenarios. The fixing part on the base plate can be used to firmly install the device onto a desktop, stand, or mobile platform using screws, magnets, or clips, ensuring that the device will not be displaced or damaged due to external disturbances during sampling and detection. This design enhances the device's adaptability and operational reliability in complex environments, making it particularly suitable for on-site testing tasks that require long-term continuous operation or high equipment stability, further improving the practicality and operational safety of the biological detection device.
[0060] In one embodiment, please refer to Figure 5 , Figure 6 and Figure 9 The detection component 300 includes a detection module 310 and a detection connector 320. The detection module 310 is disposed on the device body 100. The detection connector 320 is provided with at least two independent output channels 322 connected to the internal channel 321 of the detection connector 320. The detection connector 320 is connected to the device body 100 and can be connected to the outside of the device body 100. The detection module 310 selects one output channel 322 to detect the object to be tested 400 in the channel 321 of the device body. It can be understood that the detection module 310 detects the object to be tested 400 in the detection connector 320 through the output channel 322. The detection connector 320 is provided with multiple independent output channels 322, which provides the detection module 310 with multiple ways to detect the object to be tested 400, effectively solving the problems of traditional bioaerosol detection devices having single function, poor expandability, and inability to flexibly adapt to different detection needs. By setting multiple independent output channels 322 in the detection connector 320, interface support is reserved for possible future functional expansion; and the detection module 310 can select one of the output channels 322 to connect to and detect the test piece 400 in the channel 321 according to actual needs, thereby improving the intelligence level and operational adaptability of the entire detection process.
[0061] The two output channels 322 can be configured as two channels of different sizes, corresponding to the test pieces 400 requiring different detection accuracies, as mentioned above regarding the two specifications of the test pieces 400. When this detection component 300 is installed, it is no longer necessary to assemble multiple detection components 300 with different accuracy to meet the different accuracy requirements for detecting different microorganisms. In practical use, the purchasing personnel only need to report the required accuracy standard to the manufacturer in advance. The manufacturer will then assemble and connect one side of the output channel 322 with the corresponding accuracy on one of the detection connectors 320 to the corresponding detection module 310 according to the purchasing requirements. This overcomes the previous technical problem of manufacturers having to produce different detection connectors 320 to accommodate different detection accuracies, which was time-consuming and wasteful of materials. It should be noted that the axial angle between the two output channels 322 is less than 180°. If they are set vertically, since the different detection modules 310 are located on the same side of the detection connector 320, the axial direction of the two output channels 322 needs to have a certain angle, which needs to be less than 180° to correspond with the different detection modules 310. Specifically, when different detection accuracies need to be adjusted during assembly, it is only necessary to adjust the corresponding direction of the output channel 322 of the detection connector 320 relative to the detection module 310, and then start the detection operation of the corresponding accuracy in the detection module 310. Here, adjusting the orientation of the output channel 322 of the detection connector 320 can be achieved by rotating the detection connector 320, which is rotatably connected to the device body 100.
[0062] Furthermore, in this embodiment, please continue to refer to... Figure 5 , Figure 6 and Figure 9 The output channel 322 is located on the horizontal side of the detection connector 320. In the direction away from the inner channel 321 of the detection connector 320, the output channel 322 is flared. To ensure a more secure assembly between the detection connector 320 and the detection module 310, and to prevent the detection connector 320 from shifting relative to the detection module 310 during assembly, the output channel 322 is flared, such as with a flared step or a flared inclined wall. After the output channel 322 contacts and connects with the detection module 310, the assembly end of the detection module 310 abuts against the wall of the channel 321 of the output channel 322, thus preventing the detection connector 320 from shifting relative to the detection module 310 and ensuring a more secure assembly. In addition, the flared output channel 322 allows the assembly end of the detection module 310 to abut against the wall of the channel 321 of the output channel 322, so that the connection between the detection module 310 and the output channel 322 is sealed, thereby preventing light leakage when the detection module 310 detects the substance to be detected in the test piece 400, thus ensuring the smooth execution of the detection.
[0063] In one embodiment, please continue following Figure 5 , Figure 6 and Figure 9 The detection connector 320 is rotatably mounted on the device body 100 around its inner channel 321, and one output channel 322 connects to the detection module 310, while the other output channel 322 is covered. Without loss of generality, the outer periphery of the output channel 322 also has a sealing plate capable of sealing it, which is detachably mounted on the outer periphery of the output channel 322. When one output channel 322 is needed for detection, the other output channel 322 needs to be sealed with the sealing plate to prevent inaccurate detection of the substance to be detected in the test piece 400 due to light leakage during detection.
