Like elements are referenced with like numerals throughout the specification and figures. Many of the details described herein are intended to provide an understanding of the application. However, it is apparent to one skilled in the art that some features, functions, compositions, or methodologies described herein can be omitted, or substituted for, by alternative features, functions, compositions, or methodologies in order to accomplish the same or similar results. In some instances, some of the operations described herein are not shown or described in the specification in order to avoid obscuring the core elements of the application, and in order to avoid unnecessarily obscuring the application beyond what is necessary for one of ordinary skill in the art to understand the application based on the disclosure herein and the general knowledge of the art.

[0040] In addition, features, operations, or functions described in the specification can be combined in any suitable manner in various embodiments. Moreover, the sequences in which various steps or acts are performed can be altered in any suitable manner, unless otherwise specifically limited, to assist with understanding various embodiments of the application. Therefore, the various sequences outlined herein are merely examples, and the order of various steps or acts can be changed unless otherwise specified or required.

[0041] The terms "first", "second", "third", etc., as used herein, are used only to distinguish one element from another, and do not necessarily have any ordinal or technical meaning. The terms "connect", "couple", etc., as used herein, include direct and indirect connections (couplings) unless otherwise specified.

[0042] Referring to FIG. 1 and FIG. 2, the application provides a point-of-care testing device, which can be used to implement at least one point-of-care testing item.

[0043] The point-of-care testing device includes a control module 10 and at least one point-of-care testing module 20. As shown in FIG. 1, the point-of-care testing device includes two point-of-care testing modules 20, and as shown in FIG. 2, the point-of-care testing device includes one point-of-care testing module 20. Of course, the number of point-of-care testing modules 20 is not limited to two or one, and can be three, four, or more.

[0044] In some embodiments, the point-of-care testing module 20 is used to test a sample to obtain a testing result of the sample, or each point-of-care testing module 20 can independently test a sample to obtain a corresponding testing result. In other embodiments, the point-of-care testing module 20 is used to test a sample to obtain intermediate testing data, which needs to be processed to obtain a testing result of the sample.

[0045] In some embodiments, the instant detection module 20 can include at least one of the following: an immunochromatographic detection device, a microfluidic biochemical detection device, a urine dry-chemical detection device, a blood gas and electrolyte detection device, a blood cell detection device. For example, when the instant detection module 20 includes a microfluidic biochemical detection device, the instant detection module 20 can be referred to as a microfluidic biochemical detection module; when the instant detection module 20 includes an immunochromatographic detection device, the instant detection module 20 can be referred to as an immunochromatographic detection module. When the instant detection device includes a plurality of instant detection modules 20, the types of detection devices included in different instant detection modules 20 can be the same or different.

[0046] The instant detection module 20 can also include a sample pre-detection operation assembly for performing relevant operations on the sample during the period from when the sample is added to when the sample can be detected by the detection device. The sample pre-detection operation assembly can implement at least one of the following functions: sample preparation, reagent / consumable preparation, incubation reaction, state monitoring. For example, in some embodiments, the sample pre-detection operation assembly can include an assembly for processing the sample into a processed sample that can be detected by the detection device in the instant detection module 20, a scanning assembly for helping to identify the identity of the sample or reagent, a handling assembly for handling the sample or reagent, etc. In addition, the sample pre-detection operation assembly can also be an assembly that only performs part of the operations in the processes of sample preparation, reagent / consumable preparation, incubation reaction, and / or state monitoring, etc. In different types of instant detection modules 20, the sample pre-detection operation assembly can be arranged differently according to the type. Of course, in other embodiments, the sample pre-detection operation assembly can be omitted from the instant detection module 20, and these operations can be performed by other components outside the instant detection module 20 or manually by a person.

[0047] For example, in a microfluidic biochemical detection module, the sample needs to be subjected to centrifugal motion before detection, so that the sample and the corresponding diluent are mixed and flow into the designated position of the microfluidic chip. In some embodiments, the sample pre-detection operation assembly of the microfluidic biochemical detection module can include a disc centrifugation mechanism for centrifuging the microfluidic chip. Of course, in other embodiments, the sample pre-detection operation assembly can also include a disc in-out mechanism (a mechanism for inserting and withdrawing the microfluidic chip), a temperature control module (a module for constant temperature of the microfluidic chip), and a calibration QR code reading module, etc.

[0048] The sample pre-detection operation assembly of the immunochromatographic detection module can include a temperature control module (a module for maintaining the temperature of the reagent card). In addition, in some embodiments, the sample pre-detection operation assembly can further include a reagent card access mechanism (a mechanism for inserting and withdrawing the reagent card), a scanning mechanism (a mechanism for driving the optical to scan the detection area of the reagent card), an ID card reading module (a module for storing the calibration information on the ID card), and the like.

[0049] As shown in FIG. 1, the control module 10 has a first housing 11, and the control module 10 includes a main control unit 12, a first communication interface 13, and a first matching circuit 14. The main control unit 12 is connected with the first communication interface 13, and the first matching circuit 14 is connected with the first communication interface 13.

[0050] The first communication interface 13 is capable of being connected with at least one instant detection module 20.

[0051] In some embodiments, the main control unit 12 is configured to send a control instruction to the corresponding instant detection module 20 according to a user operation, so as to control the detection assembly 22 of the instant detection module 20 to perform an instant detection operation on a sample.

[0052] For example, the control module 10 further includes a display unit (not shown in the figure), and the display unit is connected with the main control unit 12. The main control unit 12 can provide an operation interface through the display unit, and can send a control instruction to the corresponding instant detection module 20 according to a user operation on the operation interface. For example, the operation interface includes a trigger area corresponding to each instant detection module 20, and a control instruction is sent to the instant detection module 20 corresponding to the trigger area according to a trigger area triggered by the user.

[0053] For example, the at least one instant detection module 20 is provided with a trigger member, such as a physical trigger member or a virtual trigger member, and the detection assembly 22 of the instant detection module 20 can be triggered to perform an instant detection operation on a sample according to a trigger operation of the trigger member by the user.

[0054] In some embodiments, the main control unit 12 can obtain detection data obtained by the instant detection module 20 performing an instant detection operation on a sample, such as a detection result obtained by the instant detection module 20, and / or intermediate detection data obtained by the instant detection module 20. The main control unit 12 can obtain a detection result of a sample by processing the intermediate detection data. For example, the detection result and / or the intermediate detection data can be displayed through the display unit.

[0055] Specifically, as shown in FIG. 1, each instant detection module 20 has a second housing 21 independent of the first housing 11, or in other words, the instant detection module 20 can be an entity independent of the control module 10.

[0056] In some embodiments, the second housing 21 of the at least one instant detection module 20 is detachably connected with the first housing 11. Exemplarily, the detachable connection can be at least one of clamping, screwing, magnetic attraction, fastener fixing, and bonding.

[0057] Each instant detection module 20 is also an independent entity. The second housing 21 of the at least one instant detection module 20 is detachably connected with the second housing 21 of another instant detection module 20. Exemplarily, the detachable connection can be at least one of clamping, screwing, magnetic attraction, fastener fixing, and bonding.

[0058] The control module 10 is connected with the at least one instant detection module 20 as a whole instant detection device. When the instant detection module 20 is multiple, the instant detection device can realize detection of multiple samples and / or multiple detection items of the samples.

[0059] As shown in FIG. 1 and FIG. 2, the instant detection module 20 comprises a detection assembly 22, a first interface assembly 23, a second interface assembly 24, and a second matching circuit 25. The detection assembly 22 is used for detecting samples to obtain detection data. The first interface assembly 23 of the at least one instant detection module 20 is detachably connected with the first communication interface 13. The detection data obtained by the detection assembly 22 can include detection results and / or intermediate detection data.

[0060] In some embodiments, the first interface assembly 23 can comprise at least one of a quick release connector, a pogo pin connector, and a gold finger connector. Correspondingly, the interface assembly of the first communication interface 13 can also comprise at least one of a quick release connector, a pogo pin connector, and a gold finger connector. Optionally, the connector type of the interface assembly of the first communication interface 13 is the same as that of the first interface assembly 23. Such connectors usually have a simple operation mode, such as pressing a button, rotating, or pushing and pulling, so that the user can quickly and conveniently connect or disconnect the instant detection module 20 and the control module 10.

[0061] The first interface assembly 23 comprises at least a second communication interface 231 connected with the detection assembly 22. The main control unit 12 is used for communication through the first communication interface 13 and the second communication interface 231, for example, the main control unit 12 is used for at least acquiring the detection data of the detection assembly 22 through the first communication interface 13 and the second communication interface 231; of course, it is not limited to this, for example, the main control unit 12 can also send detection instructions to the instant detection module 20 through the first communication interface 13 and the second communication interface 231.

[0062] As shown in FIG. 1, the second interface assembly 24 is detachably connected with the first interface assembly 23 of another instant detection module 20; and multiple instant detection modules 20 can be connected with the control module 10. The first interface assembly 23 and / or the second interface assembly 24 can include at least one of the following: a quick release connector, a pogo pin connector, a gold finger connector. Optionally, the connector type of the second interface assembly 24 is the same as the first interface assembly 23. Such connectors usually have a simple operation mode, such as pressing a button, rotating or pushing and pulling, etc., so that the user can quickly and conveniently connect or disconnect the instant detection module 20 and the control module 10.

[0063] The second interface assembly 24 includes a third communication interface 241 connected with the second communication interface 231. As shown in FIG. 1, when the second interface assembly 24 of the first instant detection module 20 connected with the control module 10 is connected with the first interface assembly 23 of another (which can be referred to as the second) instant detection module 20, the second communication interface 231 of the second instant detection module 20 is connected with the third communication interface 241 of the first instant detection module 20 and the second communication interface 231 of the first instant detection module 20; since the second communication interface 231 of the first instant detection module 20 is connected with the first communication interface 13 of the control module 10, the second communication interface 231 of the second instant detection module 20 is also connected with the control module 10, and the control module 10 can also communicate with the second instant detection module 20.

[0064] As shown in FIG. 1, a communication bus is formed between the main control unit 12 and the first instant detection module 20 and the second instant detection module 20; and as shown in FIG. 2, a communication bus is also formed between the main control unit 12 and the first instant detection module 20.

[0065] In the embodiments of the present application, the second matching circuit 25 of each instant detection module 20 is selectively connected or disconnected with the second communication interface 231.

[0066] In some embodiments, the detection assembly 22 is connected with the second matching circuit 25, and the detection assembly 22 is further configured to control the second matching circuit 25 to be disconnected from the second communication interface 231 when the second interface assembly 24 is connected with the first interface assembly 23 of another instant detection module 20; and to control the second matching circuit 25 to be connected with the second communication interface 231 when the second interface assembly 24 is not connected with the first interface assembly 23.

[0067] Please refer to Fig. 1, the second interface assembly 24 of the first instant detection module 20 is connected with the first interface assembly 23 of the second instant detection module 20, and the second matching circuit 25 of the first instant detection module 20 is disconnected with the second communication interface 231; the second interface assembly 24 of the second instant detection module 20 is not connected with the first interface assembly 23 of any instant detection module 20, and the second matching circuit 25 of the second instant detection module 20 is connected with the second communication interface 231.

[0068] Please refer to Fig. 2, the second interface assembly 24 of the instant detection module 20 is not connected with the first interface assembly 23 of any instant detection module 20, and the second matching circuit 25 of the instant detection module 20 is connected with the second communication interface 231.

[0069] By controlling the second matching circuit 25 of the instant detection module 20 at the farthest end connected with the control module 10 to connect the corresponding second communication interface 231, the matching circuit at both ends of the communication bus can be realized to ensure the communication between the main control unit 12 and each instant detection module 20. By controlling the second matching circuit 25 of the instant detection module 20 at the non-farthest end to be disconnected with the corresponding second communication interface 231, the communication between the instant detection module 20 at the farthest end and the control unit can be ensured, that is, the embodiment of the application can ensure the communication between the control module 10 and all instant detection modules 20 in the instant detection device.

[0070] In some embodiments, as shown in Fig. 3, the main control unit 12 includes a main controller 121 and a first CAN driver 122. The main controller 121 is connected with the first communication interface 13 through the first CAN driver 122. In other embodiments, the main control unit 12 includes a main controller 121, and the first CAN driver 122 can be built-in in the main controller 121.

[0071] For example, as shown in Fig. 3, the first matching circuit 14 includes a first resistor 141, the first end of the first resistor 141 is connected with the first communication terminal CAN_H of the first communication interface 13, and the second end of the first resistor 141 is connected with the second communication terminal CAN_L of the first communication interface 13.

[0072] The detection assembly 22 includes a detection unit 221 and a second CAN driver 222, and the detection unit 221 is connected with the second communication interface 231 through the second CAN driver 222. Of course, it is not limited to this, for example, the second CAN driver 222 can be built-in in the sub-controller 2231 of the detection unit 221.

[0073] The second matching circuit 25 can include a second resistor 251 and a first switch 252, the second resistor 251 and the first switch 252 are connected in series between the first communication terminal CAN_H and the second communication terminal CAN_L of the second communication interface 231. The detection unit 221 is connected with the first switch 252, and the detection unit 221 can control the first switch 252 to connect or disconnect the second resistor 251 with the second communication interface 231.

[0074] The communication bus between the control module 10 and the instant detection module 20 in the embodiment of the application adopts a bus with simple interface, medium-long distance transmission and strong anti-interference ability, such as the CAN bus mode, to realize data transmission between modules. The CAN bus mode can also facilitate the expansion of multiple instant detection modules 20. The rate of high-speed CAN communication can reach 1 Mbps at most, and the transmission distance can reach 40 meters. The CAN bus adopts differential signal transmission, only needs CAN_H and CAN_L signals, and has strong anti-interference ability. Preferably, the first resistor 141 and the second resistor 251 can be 120-ohm resistors, which can match the impedance of the communication bus and improve the anti-interference ability and reliability of data communication.

[0075] In other embodiments, different matching circuits can be provided according to different types of communication buses between the control module 10 and the instant detection module 20. For example, the matching circuit is not limited to including a resistor, and for example, can include a capacitor and / or an inductor. For example, other types of communication buses can be RS485 bus, IIC bus, SPI bus, and the like, which can mount multiple instant detection devices on the bus

[0076] In some embodiments, referring to FIG. 3, the first interface assembly 23 of the at least one instant detection module 20 further includes a first in-place terminal 232, and the second interface assembly 24 further includes a second in-place terminal 242, the second in-place terminal 242 and the second matching circuit 25 are connected with the detection assembly 22.

[0077] For example, the detection assembly 22 can determine whether the second interface assembly 24 is connected with another instant detection module 20 according to the state of the second in-place terminal 242, and control the second matching circuit 25 to be connected or disconnected with the second communication interface 231.

[0078] For example, the second in-place terminal 242 is connected with the first in-place terminal 232 of another instant detection module 20 when the second interface assembly 24 is connected with the first interface assembly 23 of another instant detection module 20, and the electrical signal of the second in-place terminal 242 when connected with the first in-place terminal 232 is different from the electrical signal of the second in-place terminal 242 when not connected with the first in-place terminal 232. The detection assembly 22 is configured to control the second matching circuit 25 to be connected or disconnected with the second communication interface 231 according to the electrical signal of the second in-place terminal 242.

[0079] For example, the electrical signal of the second in-situ terminal 242 when not connected with the first in-situ terminal 232 is high level; the electrical signal of the second in-situ terminal 242 when connected with the first in-situ terminal 232 is low level. Of course, it is not limited to this, for example, the detection assembly 22 can obtain any preset signal output by the first in-situ terminal 232 when the second in-situ terminal 242 is connected with the first in-situ terminal 232, and can control the second matching circuit 25 to be connected or disconnected with the second communication interface 231 according to the preset signal to identify another instant detection module 20. For example, when the second interface assembly 24 is connected with the first interface assembly 23 of another instant detection module 20, communication can be performed with another instant detection module 20 to identify another instant detection module 20.

[0080] Optionally, as shown in FIG. 3, the second in-situ terminal 242 is connected with high level through the pull-up resistor Rup, and the first in-situ terminal 232 is connected with low level, such as ground. Of course, it is not limited to this, for example, the second in-situ terminal 242 can be connected with low level, and the first in-situ terminal 232 can be connected with high level.

[0081] In other embodiments, whether the second interface assembly 24 is connected with the first interface assembly 23 of another instant detection module 20 can be determined in a non-contact manner, for example, through electric field coupling, optical coupling, electromagnetic field coupling between the second interface assembly 24 and the first interface assembly 23 to determine whether the second interface assembly 24 is connected with the first interface assembly 23 of another instant detection module 20.

[0082] For example, the detection assembly 22 of the instant detection module 20 at least includes the first detection device and the sub-control unit 223. For example, as shown in FIG. 3, the detection assembly 22 includes the detection unit 221 and the second CAN driver 222, and the detection unit 221 includes the first detection device (not shown) and the sub-control unit 223. Of course, it is not limited to this, for example, the sub-controller 2231 of the sub-control unit 223 itself can also have the second CAN driver 222. The first detection device is used to detect the sample to obtain detection data. For example, the sub-control unit 223 can control the first detection device to detect the sample according to the detection instruction of the control module 10, and the sub-control unit 223 can send the detection data to the control module 10 or send the processed detection data to the control module 10.

[0083] Referring to FIG. 3, the sub-control unit 223 is connected with the second in-situ terminal 242 and the second matching circuit 25, and the sub-control unit 223 is used to control the second matching circuit 25 to be connected or disconnected with the second communication interface 231 according to the electrical signal of the second in-situ terminal 242.

[0084] For example, the sub-control unit 223 further comprises a sub-controller 2231 connected with the first detection device and the second communication interface 231, and the sub-controller 2231 is configured to control the first detection device to detect the sample according to the control instruction of the control module 10, process the detection data of the first detection device, and send the processed detection data to the control module 10. Of course, the sub-controller 2231 can also send the detection data of the first detection device to the control module 10 for processing.

[0085] Optionally, the sub-controller 2231 is connected with the second in-place terminal 242 and the second matching circuit 25, and the sub-controller 2231 is configured to control the second matching circuit 25 to be connected or disconnected with the second communication interface 231 according to the electrical signal of the second in-place terminal 242. The sub-controller 2231 can also determine whether the second interface assembly 24 is connected with the first interface assembly 23 of another instant detection module 20 according to the electrical signal of the second in-place terminal 242, and send the determined result to the control module 10, and the control module 10 can determine the position of the instant detection module 20 on the communication bus.

[0086] Optionally, as shown in FIG. 3, the sub-control unit 223 at least comprises a resistance control circuit 2232 connected with the second in-place terminal 242 and the second matching circuit 25, and the resistance control circuit 2232 is configured to control the second matching circuit 25 to be connected or disconnected with the second communication interface 231 according to the electrical signal of the second in-place terminal 242. As shown in FIG. 3, the sub-control unit 223 comprises the sub-controller 2231 and the resistance control circuit 2232, and the resistance control circuit 2232 is specially configured to control the second matching circuit 25 to be connected or disconnected with the second communication interface 231 according to the electrical signal of the second in-place terminal 242.

[0087] In some embodiments, referring to FIG. 4, the first in-place terminal 232 can be connected to a low level through a second switch K. The second switch K can be controlled to be open, for example, by the sub-controller 2231, when the second interface assembly 24 is not connected to the first interface assembly 23 of another instant detection module 20, and the second matching circuit 25 fails to connect to the second communication interface 231. As shown in FIG. 4, when the second interface assembly 24 of the second instant detection module 20 is not connected to another instant detection module 20, and the second matching circuit 25 of the second instant detection module 20 fails to connect to the second communication interface 231, for example, when the first switch 252 or the resistance control circuit 2232 fails, by controlling the second switch K to be open, the second in-place terminal 242 of the first instant detection module 20 can correspond to a result that the second interface assembly 24 of the first instant detection module 20 is not connected to another instant detection module 20, and the second matching circuit 25 of the first instant detection module 20 is connected to the second communication interface 231 of the first instant detection module 20, so as to enable higher quality communication between the controller and the first instant detection module 20.

[0088] Referring to FIG. 5, in some embodiments, the control module 10 further comprises a first power supply circuit 15 and a first power supply interface 16, and the first power supply circuit 15 is connected to the first power supply interface 16. The first interface assembly 23 further comprises a second power supply interface 233, and the second power supply interface 233 of the instant detection module 20 is connected to the first power supply interface 16 when the first interface assembly 23 is connected to the control module 10, so as to obtain power from the first power supply interface 16, and the obtained power can at least supply the detection assembly 22 of the instant detection module 20.

[0089] As shown in FIG. 5, the second interface assembly 24 further comprises a third power supply interface 243, and the third power supply interface 243 is connected to the second power supply interface 233; the third power supply interface 243 is connected to the second power supply interface 233 of another instant detection module 20 when the second interface assembly 24 is connected to the first interface assembly 23 of another instant detection module 20, so as to supply power to the another instant detection module 20, for example, to supply the detection assembly 22 of the another instant detection module 20.

[0090] For example, the instant detection module 20 further comprises a second power supply circuit 26, and the second power supply circuit 26 is connected to the second power supply interface 233 and the detection assembly 22. The second power supply circuit 26 can supply the detection assembly 22 with power obtained from the second power supply interface 233, for example, by performing voltage conversion, filtering, and the like to provide appropriate power to the detection assembly 22.

[0091] Optionally, as shown in FIG. 5, the third power interface 243 is connected with the second power interface 233 through the second power circuit 26, and the second power circuit 26 supplies power to the third power interface 243 based on the power obtained through the second power interface 233.

[0092] For example, after the control module 10 is powered on, the power can be output through the first power interface 16, the first instant detection module 20 obtains the power and is powered on, and the third power interface 243 can be supplied with power by the second power circuit 26, so that another instant detection module 20 connected with the third power interface 243 obtains the power and is powered on.

[0093] For example, after the first instant detection module 20 obtains the power and is powered on, it can be determined whether the second interface assembly 24 is connected with another instant detection module 20 according to the electrical signal of the second in-situ terminal 242; after it is determined that the second interface assembly 24 is connected with the second instant detection module 20, the second matching circuit 25 is controlled to be disconnected with the second communication interface 231, and the second power circuit 26 is controlled to supply power to the third power interface 243, so that the second instant detection module 20 obtains the power and is powered on, and it is determined whether the second interface assembly 24 of the second instant detection module 20 is connected with another instant detection module 20; thereby, the step-by-step power-on of the instant detection module 20 and the determination of whether there is a next-level instant detection module 20 can be realized, the connection between the second matching circuit 25 and the second communication interface 231 of the instant detection module 20 is disconnected when there is a next-level instant detection module 20, the second matching circuit 25 of the instant detection module 20 that is not the farthest end is controlled to be disconnected with the corresponding second communication interface 231, so as to ensure the communication between the instant detection module 20 that is the farthest end and the control unit. Moreover, the second power circuit 26 can not supply power to the third power interface 243 when there is no next-level instant detection module 20, so as to improve the safety.

[0094] Optionally, the third power interface 243 can also be directly connected with the second power interface 233, and the second power circuit 26 is connected with the second power interface 233. After the control module 10 is powered on, the power can be output through the first power interface 16, and each instant detection module 20 can quickly obtain the power to start, so as to improve the starting efficiency.

[0095] In some embodiments, the main control unit 12 is further configured to configure a communication address of each instant detection module 20, and the communication addresses of different instant detection modules 20 are different. For example, each instant detection module 20 can not need to be assigned a unique CAN address when it is produced, and for example, each instant detection module 20 can share a CAN address. After the instant detection module 20 is assembled into the instant detection device, the instant detection module 20 can be automatically assigned a communication address after the instant detection device is powered on, and communication between instant detection devices can be realized. For example, the sub-controller 2231 of the instant detection module 20 can store the communication address assigned to itself, and communicate with the control module 10 based on the communication address.

[0096] In some embodiments, referring to FIG. 4, the instant detection device includes the control module 10 and at least one instant detection module 20, the at least one instant detection module 20 is sequentially connected in series, and the first instant detection module 20 is connected to the control module 10.

[0097] When the instant detection module 20 is powered on and the second interface assembly 24 is connected to the first interface assembly 23 of another instant detection module 20, the instant detection module 20 can send a first preset signal, the control module 10 can receive the first preset signal through the communication bus and assign a communication address to the instant detection module 20 according to the first preset signal, and the instant detection module 20 can receive the communication address assigned by the control module 10 according to the first preset signal. The communication address assigned to the instant detection module 20 is different from the communication address of the control module 10 and different from the communication addresses of other instant detection modules 20 that have been assigned.

[0098] When the instant detection module 20 is powered on and the second interface assembly 24 is not connected to the first interface assembly 23 of another instant detection module 20, the instant detection module 20 can send a second preset signal, the control module 10 can receive the second preset signal through the communication bus and assign a communication address to the instant detection module 20 according to the second preset signal, and the instant detection module 20 can receive the communication address assigned by the control module 10 according to the second preset signal. The communication address assigned to the instant detection module 20 is different from the communication address of the control module 10 and different from the communication addresses of other instant detection modules 20 that have been assigned.

[0099] Specifically, the second preset signal is further configured to indicate that the instant detection module 20 is the last one in the instant detection modules 20 connected in series, so that the control module 10 stops assigning the communication address. For example, the operation of assigning the communication address can be stopped after the instant detection module 20 sending the second preset signal is assigned the communication address, and the operation interface of the display unit can also display information of the instant detection module 20 that has been assigned the communication address.

[0100] For example, when the instant detection device includes multiple instant detection modules 20, during the power-on process of the instant detection device, the control module 10 can assign an address to each instant detection module 20 according to the connection order of the instant detection modules 20 and the control module 10, or the order of the first preset signal and the second preset signal. For example, the CAN address of the control module 10 is 10 by default, the CAN address of the first instant detection module 20 is automatically increased by 10, i.e., 20, and the CAN address of the second instant detection module 20 is automatically increased by 10, i.e., 30. This can avoid communication address conflicts between different instant detection modules 20.

[0101] For example, when the instant detection module 20 is connected to the first interface assembly 23 of another instant detection module 20 through the second interface assembly 24, the instant detection module 20 supplies power to the other instant detection module 20 to start up. For example, after the first instant detection module 20 obtains power and starts up, it is determined whether the second interface assembly 24 is connected to another instant detection module 20. After it is determined that the second interface assembly 24 is connected to the second instant detection module 20, the second power supply circuit 26 supplies power to the third power supply interface 243 to enable the second instant detection module 20 to obtain power and start up. This realizes step-by-step startup of the instant detection module 20 and determination of whether there is a next instant detection module 20, so that the control module 10 can assign communication addresses to the instant detection modules 20 one by one.

[0102] The instant detection device provided by the embodiments of the present application can accurately assign a unique CAN address to each instant detection module 20 (or an instant detection module in place) in the instant detection device, even if the number of instant detection modules 20 in the instant detection device is increased or decreased, so that the control module 10 can normally communicate with each instant detection module 20 in place.

[0103] The first interface assembly 23 of the instant detection module 20 comprises a second communication interface 231, the second interface assembly 24 comprises a third communication interface 241, and the third communication interface 241 is connected with the second communication interface 231; the second communication interface 231 of the first instant detection module 20 is connected with the first communication interface 13; the instant detection module 20 controls the second matching circuit 25 to be disconnected with the second communication interface 231 when the second interface assembly 24 is connected with the first interface assembly 23 of another instant detection module 20; and the second matching circuit 25 is connected with the second communication interface 231 when the second interface assembly 24 is not connected with the first interface assembly 23. The matching circuits can be arranged at both ends of the communication bus to ensure the communication between the main control unit 12 and the instant detection modules 20.

[0104] In some embodiments, the first communication interface 13 and the first power interface 16 of the control module 10 are arranged on the first shell 11; and the first interface assembly 23 and the second interface assembly 24 of the instant detection module 20 are arranged on the second shell 21. The first interface assembly 23 can be connected with the first communication interface 13 and the first power interface 16 when the second shell 21 of at least one instant detection module 20 is connected with the first shell 11; and the second shell 21 of at least one instant detection module 20 can be detachably connected with the second shell 21 of another instant detection module 20. The instant detection modules 20 can be expanded when the second shells 21 of different instant detection modules 20 are connected, and the detection capability of the instant detection device can be improved.

[0105] For example, the first communication interface 13 and the first power interface 16 are arranged on the bottom of the first shell 11; the first interface assembly 23 of at least one instant detection module 20 is arranged on the top of the second shell 21, and the second interface assembly 24 is arranged on the bottom of the second shell 21. The control module 10 can form a certain height by stacking the instant detection modules 20, so as to facilitate the user to operate the control module 10 and view information from the control module 10. Moreover, the control module 10 is above the instant detection modules 20, which is convenient for taking and placing samples on the instant detection modules 20.

[0106] In some embodiments, the control module 10 further comprises a display unit (not shown) connected with the main control unit 12; the main control unit 12 is further configured to control the display unit to display module information of at least one instant detection module 20, the module information comprising at least one of the following: module identification, position in the instant detection device, detection item, detection state, fault state, communication address of the instant detection module 20, so that the user can know the module information of each instant detection module 20 in the instant detection device, such as supported detection items and states. For example, the user can trigger the corresponding instant detection module 20 to perform detection of the corresponding item as needed.

[0107] The instant detection device provided by the embodiments of the present application can realize multiplexing of a plurality of instant detection modules 20 with one control module 10, facilitate the user to expand instant detection modules 20 in the same instant detection device, and has high integration, small size, high cost performance, low coupling degree, and convenient disassembly and assembly; the detection function is modularized, which facilitates positioning, disassembly and maintenance, and product iteration and upgrading. Moreover, the second matching circuit 25 of each instant detection module 20 can be connected or disconnected with the corresponding second communication interface 231, so as to ensure the communication between the control module 10 and all instant detection modules 20 in the instant detection device.

[0108] It can be understood that the embodiments of the present application also provide an instant detection module 20, which will be described in combination with the foregoing embodiments with reference to FIG. 6.

[0174] The instant detection device provided by the embodiments of the present application can accurately allocate a unique CAN address to each instant detection module (or an instant detection module in place) in the instant detection device, and ensure that the control module and each instant detection module in place can normally communicate.

[0175] The specific principles and implementation manners of the control method of the instant detection device provided by the embodiments of the present application are similar to those of the instant detection device of the foregoing embodiments, which will not be described herein.

[0176] Please refer to the foregoing embodiments in conjunction with FIG. 11. The embodiments of the present application provide a modularly designed instant detection device. The main control part and the detection part of the instant detection device can be physically separated. The module responsible for sampling and detection functions is separated out. The modules are connected through the form of a bus. They share a set of control modules. In this way, the cost is saved, the degree of reuse is improved, the detection function is modularized, the positioning of problems, disassembly and maintenance are facilitated, and product iteration and upgrading are facilitated.

[0177] The general functions are divided into control modules, and the sampling and detection functions are divided into detection modules. As shown in FIG. 12, a single instant detection device can be composed of one control module and multiple instant detection modules. The control module can include a main control subsystem and a power supply subsystem. The main control subsystem and the power supply subsystem respectively provide a communication bus and a power supply bus. Various instant detection modules are mounted to the buses. The internal structures of various instant detection modules are similar. Each instant detection module includes a specific machine electronic system and an acquisition subsystem. They are responsible for differentiated detection functions, such as the above-mentioned immunochromatographic detection, blood gas detection, biochemical detection, etc. These instant detection modules can work by relying on the power supply of the power supply subsystem. They interact with the main control subsystem through the communication bus, receive control instructions from the main control subsystem, and return data obtained by acquisition and detection.

[0178] Please refer to FIG. 13. The control module and the instant detection module, and different instant detection modules can adopt a quick-release interface for easy disassembly. The quick-release interface is used to connect the communication bus and the power supply bus. Through this bus connection mode, multiple detection modules can be mounted. The failure of a single instant detection module will not affect the work of other modules. At the same time, it is convenient for service personnel to locate module problems. When maintaining, only the faulty module needs to be replaced.

[0179] The power supply bus can adopt a rated direct current voltage for power supply. The voltage needs to meet the power supply requirements of various instant detection modules. The power supply subsystem of the control module provides sufficient output power. The bus voltage can be converted into the internal voltage value required by each instant detection module inside the module. The bus voltage can adopt a voltage lower than 36V direct current. Even if the human body touches the power supply of the quick-release interface, there is no risk of electric shock.

[0180] Please refer to Table 1. The signals of the quick-release interface include the bus power voltage, the ground, the CAN bus signal, and the in-place signal of each module. The definition of the quick-release interface needs to be simple and reliable, and has strong reusability. Each module adopts the same interface, which facilitates the extension and access of different modules.

[0181] Table 1 Definition of Quick-Release Interface

[0182] The communication bus adopts a bus with simple interface, medium-long distance transmission and strong anti-interference capability. The application adopts a CAN bus mode to realize cross-module data transmission and facilitate multi-module expansion. The high-speed CAN communication has a maximum rate of 1 Mbps and a transmission distance of 40 meters. It adopts differential signal transmission, only needs CAN_H and CAN_L signals, and has strong anti-interference capability. By using a 120-ohm terminating resistor and intelligent distribution of CAN addresses, the expansion of multiple modules can be realized. Moreover, the bus has a self-diagnosis function, automatically detects and distinguishes errors, and timely discovers error codes and packet loss problems.

[0183] A unified quick disassembly interface is adopted between modules. When the equipment is shipped, different modules can be assembled into finished products according to configuration requirements. For example, if a user needs to configure functions 1 and 2, only one control module, one instant detection module 1 and one instant detection module 2 need to be spliced one by one to form a finished product that meets the configuration. If a customer needs to configure functions 1 and 3, only instant detection module 2 needs to be modified into instant detection module 3. The unified quick disassembly interface has the advantages of strong scalability, convenient disassembly and assembly, convenient configuration and combination, and product iteration and update.

[0184] Referring to FIG. 14, the application embodiment can also automatically switch the matching circuit on the communication bus according to the in-place signal of the next instant detection module, such as switching the 120-ohm terminating resistor. When the equipment is powered on each time, each instant detection module can monitor the in-place signal of the next instant detection module to determine whether the next module is connected. If the next module is connected, the detection module is determined to be an intermediate module, and the 120-ohm terminating resistor can be disconnected. If there is no next module connected, the detection module is determined to be a terminal module, and the 120-ohm terminating resistor is connected, completing the CAN bus loop. As can be seen, each instant detection module can use the same detection method to determine its position on the CAN bus. Even if the instant detection module is added or removed in the instant detection device, the control module can accurately assign a unique CAN address to the instant detection module (or the in-place instant detection module) in the instant detection device, ensuring that the control module and each in-place instant detection module can communicate normally.

[0186] It should also be understood that the term "and / or" used in the application and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0187] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
