[0030] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0031] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0032] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0033] See also Figure 1 The present application provides a point-of-care testing device, which can be used to implement at least one point-of-care testing item.

[0034] In some embodiments, the instant detection device includes one or more instant detection modules, and the instant detection module may include at least one of the following: an immunochromatographic detection module, a microfluidic biochemical detection module, a urine dry chemical detection module, a blood gas and electrolyte detection module, and a blood cell detection module; for example, when the instant detection module includes a microfluidic biochemical detection module, the instant detection module may be referred to as a microfluidic biochemical detection module; when the instant detection module includes an immunochromatographic detection module, the instant detection module may be referred to as an immunochromatographic detection module. When the instant detection device includes multiple instant detection modules, the types of detection modules included in different instant detection modules may be the same or different.

[0035] The instant detection module may also include a sample pre-detection operation component, which is used to perform relevant operations on the sample in the process from the time the sample is added to the time the sample can be detected by the detection module. The sample pre-detection operation component can realize at least one of the following functions: sample preparation, reagent / consumable material preparation, incubation reaction, and state monitoring. For example, in some embodiments, the sample pre-detection operation component may include a component that processes the sample as required into a processed sample that can be detected by the detection module in the instant detection module, a scanning component that helps identify the identity of the sample or reagent card, and a conveying component for conveying the sample or reagent. In addition, the sample pre-detection operation component may also be a component that only performs a part of the operations in the process of sample preparation, reagent / consumable material preparation, incubation reaction, and / or state monitoring. In different types of instant detection modules, the sample pre-detection operation component may be set differently depending on the type. Of course, in other embodiments, the sample pre-detection operation component may also be omitted in the instant detection module, and these operations may be performed by other components outside the instant detection module or manually.

[0036] For ease of explanation, the embodiments of the present application are mainly described by taking the example that the point-of-care detection device includes an immunochromatographic detection module. In some embodiments, the point-of-care detection device also includes a microfluidic biochemical detection module.

[0037] The sample pre-test operation component of the immunochromatographic detection module may include a temperature control module (a module for incubating the reagent card at a constant temperature). In addition, in some embodiments, the sample pre-test operation component may also include a reagent card entry and exit mechanism (a mechanism for inserting and exiting the reagent card), a scanning mechanism (to identify the identity of the sample and / or reagent card), an ID card reading module (to store the calibration information on the ID card), etc.

[0038] Before the microfluidic biochemical detection module detects the sample, it needs to be centrifuged so that the sample and the corresponding diluent are mixed and flow into the set position of the microfluidic chip. In some embodiments, the sample pre-detection operation component of the microfluidic biochemical detection module may include a disc centrifugal mechanism for centrifuging the microfluidic chip. Of course, in other embodiments, the sample pre-detection operation component may also include a disc entry and exit mechanism (a mechanism for inserting and exiting the microfluidic chip), a temperature control module (a module for maintaining a constant temperature of the microfluidic chip), and a calibration QR code reading module, etc.

[0039] like Figure 1 As shown, the instant detection device of the embodiment of the present application includes a card holder assembly 10, a detection assembly 20, a driving assembly 30 and a controller 40.

[0040] The card holder assembly 10 includes at least two carrying portions 11 , which are arranged along a first direction and are used to carry a reagent card 50 .

[0041] like Figure 1 As shown, the card base assembly 10 includes three bearing parts 11. In other examples, the card base assembly 10 includes two bearing parts 11, four bearing parts 11, or more than four bearing parts 11. The bearing parts 11 in the card base assembly 10 can be independently provided, or can also be provided in an integrated manner. In some embodiments, each bearing part 11 can be referred to as a channel.

[0042] like Figure 1 As shown, at least two bearing parts 11 of the card holder assembly 10 can be arranged along a straight line; of course, it is not limited thereto, for example, at least two bearing parts 11 of the card holder assembly 10 can be arranged along an arc.

[0043] In some embodiments, each carrying portion 11 can carry one reagent card 50, or the cartridge assembly 10 can carry a multi-pack of reagent cards 50, and the multi-pack of reagent cards 50 is provided with multiple reagent cards 50 in an integrated manner, which can be placed in the carrying portion 11 of the cartridge assembly 10 at the same time.

[0044] The instant detection device can realize multi-channel sample detection through a multi-channel structure including multiple bearing parts 11. Taking the veterinary instant detection device as an example, the use of a veterinary immunoassay analyzer with a multi-channel structure can speed up the detection rate of the veterinary reagent card 50. Multi-channel detection can greatly improve the doctor's work efficiency, reduce the doctor's waiting time when testing a large number of reagent cards 50, and meet the growing demand for veterinary immunoassays in the laboratory department.

[0045] In some embodiments, the card holder assembly 10 includes a temperature control module, which can incubate the reagent card 50 on at least one carrier portion 11 .

[0046] The detection component 20 is used to obtain relevant information of the reagent card 50 carried by the carrying portion 11 .

[0047] The relevant information of the reagent card 50 includes but is not limited to at least one of the following: the detection information of the sample on the reagent card 50, the identity information of the sample, the identity information of the reagent card 50, the identity information of the reagent on the reagent card 50, and the identity information of the testing personnel. For example, the detection information of the sample on the reagent card 50 can be obtained after the sample reacts with the reagent on the reagent card 50, or the reagent card 50 may not be provided with a reagent; the detection information of the sample can indicate whether there is a specific substance in the sample and / or indicate the content of the specific substance in the sample. The identity information of the sample can indicate the source of the sample, the identity information of the reagent card 50 can indicate the traceability information of the reagent card 50 or the number of the reagent card 50, and the identity information of the reagent on the reagent card 50 can indicate the type or concentration of the reagent, etc.

[0048] Exemplarily, the detection component 20 includes one or more image sensors, such as a first image sensor and a second image sensor, the first image sensor is used to obtain the detection information of the sample, and the second image sensor is used to obtain the identity information of the reagent card 50; of course, it is not limited to this. For example, a variety of relevant information of the reagent card 50 can be obtained through the same image sensor, or the detection information of the sample can be obtained in a non-visual manner, such as the detection information of the sample includes electrical parameters such as resistance parameters and / or capacitance parameters of the sample.

[0049] The driving assembly 30 is used to drive the detection assembly 20 to move, and can drive the detection assembly 20 to move to the carrying portion 11 .

[0050] For example, see Figure 2 The driving assembly 30 at least includes a first driving mechanism 31, on which the detection assembly 20 is disposed, and the first driving mechanism 31 is used to drive the detection assembly 20 to move in a second direction, which is parallel to the first direction (the direction in which the bearing parts 11 are arranged); for example, the first driving mechanism 31 includes a first screw rod 311 and a first slider 312, and the detection assembly 20 is connected to the first slider 312, and the first slider 312 can move on the first screw rod 311 to drive the detection assembly 20 to move in the second direction. The driving assembly 30 can drive the detection assembly 20 to move from a position outside the card holder assembly 10 to the bearing part 11, and can also drive the detection assembly 20 to move between different bearing parts 11.

[0051] In some embodiments, the driving assembly 30 further includes a second driving mechanism 32, and the second driving mechanism 32 is used to drive the detection assembly 20 to move along a third direction, and the third direction intersects with the first direction (for example, when the supporting parts 11 are arranged along a straight line, the third direction is perpendicular to the first direction); the detection assembly 20 is connected to the first driving mechanism 31 through the second driving mechanism 32, or the detection assembly 20 is arranged on the first driving mechanism 31 and the first driving mechanism 31 is arranged on the second driving mechanism 32. For example, Figure 2 As shown, the second driving mechanism 32 includes a second screw rod 321 and a second slider 322, the second screw rod 321 is connected to the first slider 312, the detection component 20 is connected to the second slider 322, the second slider 322 can move on the second screw rod 321 to drive the detection component 20 to move along the third direction, and when the first slider 312 moves on the first screw rod 311, the detection component 20 moves along the second direction.

[0052] Optionally, when the driving component 30 drives the detection component 20 to move, the first driving mechanism 31 can be controlled to drive the detection component 20 to move in the second direction and the second driving mechanism 32 can be controlled to drive the detection component 20 to move in the third direction in a time-sharing manner, and the moving trajectory of the detection component 20 is a broken line; or the first driving mechanism 31 and the second driving mechanism 32 can be controlled at the same time to drive the detection component 20 to move, and the moving trajectory of the detection component 20 is shorter, which can improve the efficiency of the movement of the detection component 20.

[0053] It should be noted that the drive assembly 30 is not limited to Figure 2 In the structure shown, for example, the driving component 30 may be a robot, etc., and the embodiment of the present application may not limit the structure of the driving component 30.

[0054] The controller 40 is used to control the driving component 30 to drive the detection component 20 to move to a preset waiting position, and in response to the detection requirement of the reagent card 50, control the driving component 30 to drive the detection component 20 to move from the preset waiting position to above the carrying part 11 carrying the reagent card 50 to obtain relevant information of the reagent card 50, and determine the detection result of the reagent card 50 according to the relevant information. There is at least one carrying part 11 on both sides of the preset plane where the preset waiting position is located, and the preset plane is perpendicular to the first direction.

[0055] Please combine Figure 1 See also Figure 3a to Figure 3f The detection component first moves to a preset waiting position to wait, and there is at least one of the bearing parts on both sides of the preset plane where the preset waiting position is located. When receiving the detection requirement of the reagent card, the detection component moves from the preset waiting position to the top of the bearing part to obtain the relevant information of the reagent card.

[0056] Please combine Figure 2 See also Figure 3f In the related art, the detection component is at the starting position by default. When the detection component is at the starting position, the slider in the driving component is usually located at the end of the screw rod or close to the end of the screw rod; when receiving the detection requirement of the reagent card, the detection component moves from the starting position to the top of the bearing part for detection. Figure 3f As shown, compared with the movement of the detection component from the starting position to the top of the carrying part, the path of the detection component of the embodiment of the present application moving from the preset waiting position to the top of each carrying part is shorter, so that the detection requirements of the reagent card can be responded to more quickly and the detection efficiency can be improved.

[0057] In some embodiments, the number of the bearing parts on both sides of the preset plane where the preset waiting position is located is equal. Figure 3a to Figure 3c or Figure 3f As shown, the preset waiting position is located in the middle of the arrangement direction of the multiple bearing parts, and the sum of the paths that the detection component moves from the preset waiting position to each bearing part is the shortest. When the reagent card on the middle bearing part needs to be detected, the detection component can move to the top of the bearing part in the shortest way to obtain the relevant information of the reagent card. For example, when the reagent card on the outer bearing part needs to be detected, no matter whether the reagent card is on the leftmost or rightmost side, the detection component can move to the top of the bearing part in a shorter way to obtain the relevant information of the reagent card.

[0058] In other embodiments, Figure 3d As shown, the number of the bearing parts on both sides of the preset plane where the preset waiting position is located is not equal, for example, the number of bearing parts on the left side of the preset plane is less than the number of bearing parts on the right side of the preset plane, that is, the preset waiting position is a position biased towards the left bearing part. When the reagent card on the bearing part on the left side needs to be detected, compared with the equal number of the bearing parts on both sides of the preset plane, the scheme of unequal number of bearing parts on both sides of the preset plane can facilitate the detection component to move to the top of the bearing part with a shorter path. It should be noted that, in the case where the user is accustomed to putting the reagent card in the bearing part on the left side first, by setting the number of bearing parts on the left side of the preset plane to be less than the number of bearing parts on the right side of the preset plane, the path of the detection component moving from the preset waiting position to the bearing part can be reduced, thereby improving the detection efficiency. Similarly, the number of bearing parts on the right side of the preset plane can also be set to be less than the number of bearing parts on the left side of the preset plane, that is, the preset waiting position is a position biased towards the right bearing part; in the case where the user is accustomed to putting the reagent card in the bearing part on the right side first, the path of the detection component moving from the preset waiting position to the bearing part can also be reduced, thereby improving the detection efficiency.

[0059] In some embodiments, the at least two carrying parts are disposed in a reagent card carrying area of ​​the cartridge assembly, and a projection of the preset waiting position on the cartridge assembly is located in the reagent card carrying area.

[0060] like Figure 3a or Figure 3e As shown, the projection of the preset waiting position on the holder assembly is located in the reagent card carrying area, and when the detection component is in the preset waiting position, the projection of the detection component on the holder assembly is located in the first direction of the carrying portion.

[0061] Exemplarily, the reagent card includes an area to be scanned. For example, see Figure 2 or Figure 3f The area to be scanned of the reagent card includes at least the sample detection area and may also include the identity information area; correspondingly, the carrier includes at least the detection start position and the detection end position corresponding to the sample detection area, and may also include the scanning position and / or the photographing position corresponding to the identity information area.

[0062] The detection component includes a scanning component, and the scanning component includes one or more image sensors. For example, when the detection component moves from the detection start position to the detection end position, it can obtain the detection information of the sample on the reagent card. The detection component can obtain at least one of the following at the scanning position and / or the photographing position of the carrier: the identity information of the sample, the identity information of the reagent card, the identity information of the reagent on the reagent card, and the identity information of the detection personnel.

[0063] For example, Figure 3a As shown, when the detection component is in the preset waiting position, it is located above a preset area of ​​at least one of the carrying parts, and the preset area is an area of ​​the carrying part corresponding to the area to be scanned; or Figure 3e As shown, when the detection component is in the preset waiting position, it can move along the first direction to above a preset area of ​​at least one of the carrying parts.

[0064] See also Figure 3b See also Figure 3a , or see Figure 3d See also Figure 3e By setting the projection of the preset waiting position on the card holder assembly to be located in the reagent card carrying area, the path of the detection component moving from the preset waiting position to the carrying part can be shortened and the time taken can be shortened. Specifically, the path and time of the detection component moving in the third direction can be saved.

[0065] In some embodiments, the controller is used to control the driving component to drive the detection component to move to the preset waiting position when the instant detection device is initialized.

[0066] like Figure 4 As shown, the instant detection device is initialized after being powered on, and the detection component moves to the preset waiting position at the end of the initialization. It should be noted that during the initialization process, before the detection component moves to the preset waiting position, the movement process of the detection component is not limited; for example, during the initialization process, the driving component first drives the detection component to move to the initial position and / or the preset calibration position or first moves to one or more positions other than the initial position, the preset calibration position, and the preset waiting position, and then moves from these positions to the preset waiting position; or during the initialization process, the driving component can drive the detection component to move directly from the position before initialization to the preset waiting position.

[0067] In some embodiments, the controller is used to control the driving component to drive the detection component to move to the preset waiting position when the detection component is idle, and the detection component does not need to obtain relevant information of any of the reagent cards when it is idle.

[0068] Exemplarily, the controller determines that the detection assembly is idle when all the carrying parts of the card holder assembly are not carrying a reagent card.

[0069] like Figure 4 As shown, when the instant detection device is initialized and all the carrying parts are not carrying reagent cards, or when all the reagent cards in the carrying parts have been ejected, the instant detection device is in state 1. In this state 1, the driving component stops driving the detection component, and the detection component waits at a preset waiting position; when receiving a detection requirement of a reagent card, the controller controls the driving component to drive the detection component to move from the preset waiting position to above the carrying part carrying the reagent card in response to the detection requirement to obtain relevant information of the reagent card.

[0070] In some embodiments, the controller is used to control the driving component to drive the detection component to move from the preset waiting position to the carrying portion carrying the reagent card when it is detected that the carrying portion carries a reagent card, and to obtain relevant information about the reagent card carried by the carrying portion.

[0071] like Figure 4 As shown, when there are one or more reagent cards on the instant testing device, the instant testing device is in state 2. In this state 2, the detection component moves from the preset waiting position to the carrying part that carries the reagent card to obtain relevant information of the reagent card carried by the carrying part.

[0072] Exemplarily, when there is a reagent card on the instant testing device, in state 2, the detection component moves from the preset waiting position to the carrying portion of the reagent card to obtain relevant information of the reagent card.

[0073] See also Figure 2 The detection component obtains relevant information of the reagent card in the carrying part, including: the controller controls the driving component to move along the third direction to the scanning position and / or the photographing position and / or from the detection starting position to the detection ending position; to obtain at least one relevant information of the reagent card.

[0074] In some embodiments, the detection mode of the reagent card includes a read-only mode and / or a standard mode. Wherein in the read-only mode, the instant detection device does not need to incubate the sample of the reagent card, for example, the detection of the sample does not require an incubation process or the sample has been incubated outside the instant detection device. In the standard mode, the instant detection device needs to incubate the sample of the reagent card before obtaining the detection information of the sample on the reagent card. For example, the controller can determine the detection mode of the reagent card according to the user operation, or can determine the detection mode of the reagent card according to the identity information of the reagent card.

[0075] like Figure 5 As shown, in state 2, the controller controls the driving component to drive the detection component to move along the third direction to the scanning position and / or the photographing position of the carrying part, so as to obtain at least one of the following through the detection component: the identity information of the sample, the identity information of the reagent card, the identity information of the reagent on the reagent card, and the identity information of the detection personnel (the signature of the detection personnel in the signature area). Figure 6 When the detection mode of the reagent card is read-only mode, the controller controls the driving component to drive the detection component to move along the third direction to the detection starting position of the carrying part, and starts to scan the sample detection area of ​​the reagent card, such as driving the detection component to move from the detection starting position to the detection ending position. During the movement, the controller obtains the detection data of the detection component as the detection information of the sample on the reagent card; if the detection data is successfully obtained, the driving component can be controlled to eject the reagent card or output a prompt message to prompt the user to remove the reagent card; if the monitoring data acquisition fails, the driving component is controlled to drive the detection component to return to the detection starting position to scan the reagent card again; if the number of failures reaches a preset number (such as three times), an alarm message is output to prompt the user that the reagent card is invalid.

[0076] For example, Figure 7 The figure shows the process flow of controlling the drive component to eject the reagent card. Figure 2 See also Figure 7, control the drive component to drive the detection component to move from the detection end position to the card ejection position. During the movement, the detection component pushes the reagent card out of the carrying part. When the reagent card is pushed out of the carrying part, the switch state of the micro switch changes. The controller can determine that the card ejection is successful based on the change in the switch state of the micro switch. If the card ejection fails, control the drive component to drive the detection component back to the detection end position to control the drive component again to eject the reagent card. If the number of failures reaches a preset number (such as three times), an alarm message is output to prompt the user that the reagent card ejection has failed.

[0077] For example, please combine Figure 4 See also Figure 8 , when there is a reagent card on the instant detection device, and the detection mode of the reagent card is read-only mode, in state 2, the controller obtains at least one of the following through the detection component: the identity information of the sample, the identity information of the reagent card, the identity information of the reagent on the reagent card, and the identity information of the detection personnel (the signature of the detection personnel in the signature area), then stops scanning the reagent card and enters the incubation countdown. After the incubation is completed, the drive component is controlled to drive the detection component to move to the detection start position of the bearing part corresponding to the reagent card, and starts scanning the sample detection area of ​​the reagent card. If other reagent cards are detected to be inserted into the instant detection device during the waiting process for incubation, the controller controls the drive component to drive the detection component to move to the bearing part of the other reagent cards to obtain the relevant information of the other reagent cards.

[0078] In some embodiments, the instant detection device further includes a display, and the controller can control the display to output at least one of the identity information of the sample, the identity information of the reagent card, the identity information of the reagent on the reagent card, and the identity information of the detection personnel (the signature of the detection personnel in the signature area), and in response to the user's confirmation operation of these information, scan the sample detection area of ​​the reagent card,

[0079] In some embodiments, when there are multiple reagent cards on the instant detection device, the controller is also used to: obtain the information acquisition order of the reagent cards carried by each of the multiple carrying parts; the controller is used to control the driving component to drive the detection component to move from the preset waiting position to at least one of the multiple carrying parts according to the information acquisition order of the reagent cards carried by each of the multiple carrying parts.

[0080] Exemplarily, the controller is used to determine the order of information acquisition of the reagent cards carried by each of the multiple carrying parts according to the order in which the multiple carrying parts carry the reagent cards, and / or the distance between the carrying parts and the preset waiting position. For example, the closer the distance to the preset waiting position, the earlier the information acquisition order of the reagent card carried by the carrying part, and the earlier the reagent card is placed in the carrying part, the earlier the information acquisition order; optionally, the reagent card carried by the carrying part with the closest distance to the preset waiting position is the first in the information acquisition order; for multiple carrying parts with close distances, the earlier the reagent card is placed, the earlier the information acquisition order is.

[0081] For example, please combine Figure 4 See also Figure 8 In state 2, for reagent cards that are at the front of the information acquisition order, at least one of the relevant information of the sample's identity information, the reagent card's identity information, the reagent's identity information on the reagent card, and the tester's identity information (the tester's signature in the signature area) can be obtained first; if the test mode of the reagent card is read-only mode (incubation outside the machine or no incubation required), the test information of the sample on the reagent card is also obtained; if the test mode of the reagent card is standard mode (incubation inside the machine), the incubation countdown begins, and if there are other reagent cards that need to obtain relevant information, the controller controls the drive component to drive the detection component to move to the carrying part of the other reagent cards to obtain relevant information of the other reagent cards.

[0082] The controller is also used to: after the detection component reads the relevant information of the reagent card carried by the carrier, determine the order of obtaining information of the reagent cards carried by the remaining carriers according to the sequence of the remaining carriers carrying the reagent cards and / or the distance between the remaining carriers and the carrying part where the reagent card from which the relevant information has been read is located; and control the driving component to drive the detection component to move from the carrying part where the reagent card from which the relevant information has been read is located to the remaining carriers according to the order of obtaining information of the reagent cards carried by the remaining carriers.

[0083] For example, please combine Figure 4 See also Fig. 9In state 3, after the detection component obtains the relevant information of a reagent card on a bearing part, if there are other reagent cards that need to be read, the reagent card whose relevant information is to be read next is determined, and the driving component is controlled to drive the detection component to move to the bearing part where the reagent card whose relevant information is to be read next is located. For example, among the remaining reagent cards, the reagent card whose bearing part is closest to the bearing part where the reagent card whose relevant information was obtained last time is located is the reagent card whose relevant information is to be read next, so that the detection component can move to the position where the reagent card is located more quickly, thereby improving the efficiency of obtaining information from the reagent card; it can prevent the reagent card from waiting for detection for a timeout to affect the accuracy of the detection data, while reducing the waiting time of the user.

[0084] In some embodiments, the controller determines that the detection component is idle when all the bearing parts of the card holder assembly are in any of the following states: the bearing part does not bear a reagent card; the relevant information of the reagent card carried by the bearing part has been acquired; the reagent card carried by the bearing part does not need to read the relevant information within a preset time. For example, the instant detection device also includes an incubation component, which is used to incubate the reagent card carried by the bearing part; when the controller incubates the reagent card carried by the bearing part, it determines that the reagent card does not need to read the relevant information within a preset time.

[0085] When the detection component is idle, the driving component is controlled to drive the detection component to move to the preset waiting position to wait. When a reagent card needs to be read, it can move from the preset waiting position to the position corresponding to the reagent card more quickly with a shorter path to obtain relevant information of the reagent card.

[0086] Exemplarily, the controller is used to control the drive component to drive the detection component to move from the preset waiting position to the bearing part, and obtain the relevant information of the reagent card carried by the bearing part when the reagent card carried by the bearing part needs to read the relevant information within a preset time. Exemplarily, multiple reagent cards on the instant detection device all need to be incubated in the machine, and the incubation time is greater than the preset time, then the detection component can wait at the preset waiting position; wait until the incubation of a reagent card is about to end or has just ended, control the drive component to drive the detection component to move from the preset waiting position to above the bearing part where the reagent card is located to obtain the relevant information of the reagent card. When there is no reagent card that needs to read the relevant information, the detection component waits at the preset waiting position, and when there is a reagent card that needs to read the relevant information, it can move more quickly to the position corresponding to the reagent card to obtain the relevant information of the reagent card.

[0087] In some embodiments, the controller is also used to control the driving component to drive the detection component to move from the carrying part where the reagent card that has read the relevant information is located to another carrying part, and to obtain the relevant information of the reagent card carried by the other carrying part.

[0088] Exemplarily, the controller is used to control the driving component to drive the detection component to move from the carrying part where the reagent card that has read the relevant information is located to the carrying part where the reagent card that needs to read the relevant information is located when the reagent card carried by the carrying part needs to read the relevant information within a preset time period.

[0089] For example, after the detection component obtains the relevant information of a reagent card carried by a certain carrying part, it can stay above the carrying part; when other reagent cards need to read the relevant information, the driving component is controlled to drive the detection component to move from the carrying part to the carrying part where the reagent card that needs to read the relevant information is located.

[0090] For example, when the detection component finishes obtaining relevant information of a reagent card carried by a certain carrying part, if it is determined that the remaining reagent cards need to read the relevant information within a preset time period, the driving component is controlled to drive the detection component to move from the carrying part to the carrying part where the reagent card that needs to read the relevant information is located.

[0091] For example, when the detection component finishes obtaining the relevant information of a reagent card carried by a certain carrying part, if it is determined that the remaining reagent cards do not need to read the relevant information within a preset time period, the driving component is controlled to drive the detection component to move from the carrying part to the preset waiting position to wait; when there is a reagent card that needs to read the relevant information, the driving component is controlled to drive the detection component to move from the preset waiting position to the carrying part where the reagent card that needs to read the relevant information is located, so that when there is a reagent card that needs to read the relevant information, the detection component can be moved more quickly to the position corresponding to the reagent card to obtain the relevant information of the reagent card.

[0092] In some embodiments, the controller is further used to control the driving component to drive the detection component to move to a preset calibration position to perform positioning calibration at the preset calibration position to eliminate the position error of the detection component.

[0093] For example, the movement of the slider on the screw rod will accumulate certain errors due to the manufacturing and process errors of the slider and the screw rod. Even if the detection device is stationary for a long time, the position of the slider on the screw rod will also produce errors due to handling, shaking, vibration, human factors, etc., which will cause errors in the position of the detection component. By performing positioning calibration to eliminate the position error of the detection component, the drive component can be controlled to drive the detection component to accurately move to the preset waiting position and above each bearing part, and the accuracy of the relevant information of the reagent card (such as the detection component) obtained by the detection component can also be improved.

[0094] Exemplarily, the controller is used to control the driving component to drive the detection component to move to a preset calibration position when the instant detection device is turned on, so as to eliminate positioning errors generated when the instant detection device is stationary or transported.

[0095] For example, please combine Figure 4 See also Fig.10 , the controller is used to control the drive assembly to drive the detection assembly to move to a preset calibration position when the instant detection device completes the detection of a preset number of reagent cards; and / or the controller is used to control the drive assembly to drive the detection assembly to move to a preset calibration position when the time interval of the most recent positioning calibration is greater than or equal to the time interval threshold. For example, the number of card withdrawals can be counted, and when the count value reaches a preset number (such as 3), the drive assembly is controlled to drive the detection assembly to move to a preset calibration position for positioning calibration. For example, when the drive assembly does not drive the detection assembly to move for half an hour, the drive assembly is controlled to drive the detection assembly to move to a preset calibration position for positioning calibration; optionally, when the drive assembly does not drive the detection assembly to move for half an hour, and there is no reagent card that needs to read relevant information within a preset time, the drive assembly is controlled to drive the detection assembly to move to a preset calibration position for positioning calibration.

[0096] For example, Fig. 9As shown, controlling the driving component to drive the detection component to move to a preset calibration position to perform positioning calibration at the preset calibration position includes: controlling the first slider of the first driving mechanism to move to the first preset position of the first screw rod for positioning calibration, and controlling the second slider of the second driving mechanism to move to the second preset position of the second screw rod for positioning calibration; wherein the detection component moves to the preset calibration position when the first slider moves to the first preset position of the first screw rod and the second slider moves to the second preset position of the second screw rod. For example, the first preset position of the first screw rod is provided with an optical coupling sensor, and when the first slider moves to the first preset position of the first screw rod, the output signal of the optical coupling sensor changes. The controller can determine that the first slider moves to the first preset position according to the change in the output signal of the optical coupling sensor. By calibrating the first preset position, the positioning calibration of the first driving mechanism can be realized; similarly, the positioning calibration of the second driving mechanism can be realized.

[0097] The preset calibration position may be a starting position of the detection component, or may be a position other than the starting position, for example, the preset calibration position may also be a preset waiting position.

[0098] Optionally, the controller is used to automatically control the drive component to drive the detection component to move from the preset calibration position to the preset waiting position after the positioning calibration is completed. For example, the detection component waits at the preset waiting position; when the detection requirement of the reagent card is received, the detection component can move to the position where the reagent card is located more quickly, thereby improving the efficiency of obtaining information from the reagent card; it can prevent the timeout of the reagent card waiting for detection from affecting the accuracy of the detection data, while reducing the waiting time of the user.

[0099] Optionally, the controller is used to control the driving component to drive the detection component to move from the preset calibration position to the bearing part after the positioning calibration is completed and when it is detected that the bearing part carries a reagent card. The detection component can move to the position where the reagent card is located more quickly, thereby improving the efficiency of obtaining information from the reagent card; it can prevent the reagent card from waiting for detection for a timeout, which affects the accuracy of the detection data, and at the same time reduce the waiting time of the user.

[0100] The instant detection device provided by the embodiment of the present application includes: a card holder component, a detection component, a drive component, and a controller; the card holder component includes at least two bearing parts, the at least two bearing parts are arranged along a first direction, and the bearing part is used to carry a reagent card; the detection component is used to obtain relevant information of the reagent card carried by the bearing part; the drive component is used to drive the detection component to move, and can drive the detection component to move to the bearing part; the controller is used to control the drive component to drive the detection component to move to a preset waiting position, and in response to the reagent card detection requirement, control the drive component to drive the detection component from the preset waiting position to the upper part of the bearing part carrying the reagent card to obtain relevant information of the reagent card, and determine the detection result of the reagent card according to the relevant information; wherein, there is at least one bearing part on both sides of the preset plane where the preset waiting position is located, and the preset plane is perpendicular to the first direction. When receiving the detection requirement of the reagent card, the detection component can move from the starting position to the upper part of the bearing part for detection, and the path of the detection component from the preset waiting position to the upper part of each bearing part is shorter, so that the detection requirement of the reagent card can be responded to more quickly, and the detection efficiency can be improved.

[0101] It should be noted that in the related art, for multi-channel instant detection equipment, there is no strong constraint on the priority and running sequence of each sub-function process in the detection scheduling process of each channel. The detection scheduling method is generally: the channel with priority insertion is scheduled for detection first. After the detection is completed, the next channel is scheduled for detection. All channels are detected in sequence according to the order in which the reagent card is inserted. When the amount of reagent card detection is relatively large or there are multiple cards, this scheduling method schedules the detection in the channel where the reagent card is inserted first. It lacks the optimization scheduling consideration of the priority of each sub-process of information acquisition, incubation, scanning detection, and card withdrawal under the entire detection process of multiple reagent cards and the movement of detection components. It lacks the distinction between continuous samples and single samples. The starting point of each detection component starts from the initial position, which does not meet the timeliness considerations of path optimization and time-saving. It lacks the consideration that the sample has a greater impact on the sample detection result as time goes by.

[0102] At least one implementation of the embodiments of the present application can achieve at least one of the following effects when testing multiple reagent cards under multiple channels: optimize the operation path of the detection component and compress the scheduling time; prioritize the timing of each sub-functional module in the detection process, decompose the scheduling, and compress the time; comprehensively consider the impact of the detection time on the sample results, reduce the doctor's waiting time for obtaining reagent card information and the time to scan the results, minimize the impact of the detection time on the sample detection, and plan the shortest mechanism action path to better meet user needs.
