Description

Medical testing equipment and test kits for medical testing equipment Technical Field

[0001] The present application relates to the field of analytical instruments, in particular to medical testing equipment and test kits for medical testing equipment. Background Art

[0002] Medical testing equipment is typically equipped with a removable test kit. While the reagents in the kit are used for sample testing, the removable kit also allows for convenient reagent replenishment or replacement. Currently, common medical testing equipment typically connects the test kit and test card via a fluid pathway within the device body, facilitating easy removal and replacement of the kit.

[0003] However, because the fluid pathways within the device body are reusable, maintaining them requires significant maintenance costs to ensure proper function. Furthermore, reagent cartridge replacement requires disassembly and assembly of the interface between the device body and the reagent cartridge. Repeated disassembly and replacement of the reagent cartridge can lead to leaks and docking difficulties, negatively impacting the durability and stability of the medical testing equipment.

[0004] Utility Model Content

[0005] The technical problem to be solved by this application is how to provide medical testing equipment and a test kit for medical testing equipment, which can solve the technical problems of high maintenance cost, low durability and stability of the main body of the medical testing equipment.

[0006] The present application provides an analytical instrument comprising a device body, a reagent cartridge, and an actuator. The reagent cartridge is interchangeably docked with the device body. The reagent cartridge comprises a first fluid pathway, comprising a fluid outlet and at least one fluid inlet. The fluid outlet is configured to connect to a test card, and the fluid inlet is configured to connect to a fluid bag / external space. A movable valve is provided between the fluid inlet and the fluid outlet of the first fluid pathway, or adjacent to the fluid inlet of the fluid bag / external space. The actuator is mounted on the device body and is configured to actuate the movable valve to open or close.

[0007] The present application provides a medical testing device comprising a device body, a reagent kit, and an actuator. The reagent kit is interchangeably docked with the device body and includes a first fluid pathway, comprising a fluid outlet and at least one fluid inlet. The fluid outlet is configured to connect to a test card, and the fluid inlet is configured to connect to a fluid bag / external space. The actuator is connected to the device body and is configured to compress the first fluid pathway to disconnect the test card from the fluid bag / external space, or to release the first fluid pathway to connect the test card to the fluid bag / external space.

[0008] The present application provides a test kit for a medical testing device, which can be replaceably docked with the device body of the medical testing device. The test kit is provided with an independent first fluid passage, and the first fluid passage has a fluid outlet and at least one fluid inlet. The fluid outlet is used to connect to a test card, and the fluid inlet is used to connect to a liquid bag / external space. A movable valve body is provided between the fluid inlet and the fluid outlet of the first fluid passage, or at the fluid inlet adjacent to the liquid bag / external space. The movable valve body is used to open or close under the drive of an actuator.

[0009] Different from the prior art, the present application discloses a medical testing device and a test kit for the medical testing device, which can connect the test card and the liquid bag / external space using a first fluid passage separately provided in the test kit. The device body does not need to be provided with a fluid passage, and the execution component on the device body is not in the first fluid passage. Therefore, integrating the fluid conveying structure of the medical testing device into the test kit can reduce the sealing requirements and maintenance costs of the device body and improve the stability and durability of the medical testing device.

[0038] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] The terms "first," "second," and the like in this application are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "comprising," and "provided with," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0040] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] With the advancement of analytical technology, medical testing equipment is generally equipped with detachable integrated test kits, which makes it easier to replenish or replace reagents and gases in medical testing equipment. The inventors of this application have discovered that the detachable nature of the test kits raises concerns about the sealing of the interface between the test kit and the test card or medical testing equipment, as well as the maintenance of the fluid pathways within the main body of the medical testing equipment.

[0042] Because the main body of medical testing equipment is equipped with many sensitive detection devices, it is very troublesome to disassemble, maintain, or replace them. The liquid circuit installed in the main body of the equipment is also inconvenient to maintain and cannot be replaced frequently like the test kit. Once damaged, not only will there be leakage problems, but it may also cause damage to the equipment and bring huge repair costs. As for the docking interfaces between the test kit and the main body of the equipment, and between the main body of the equipment and the test card, since the test kit and the test card are consumables, the docking interfaces on one side of the main body of the equipment will inevitably age gradually after repeated use, resulting in problems such as reduced sealing and difficulty in assembly, which is not conducive to the stability and durability of medical testing equipment.

[0043] How to provide medical testing equipment and test kits for medical testing equipment, reduce the probability of fluid path failure, and improve the stability and durability of medical testing equipment is a major problem that this application aims to solve.

[0044] Referring to Figures 1 and 2, Figure 1 is a schematic diagram of the fluid pathway structure of an embodiment of the medical testing device of the present application. Figure 2 is a schematic diagram of the structure of an embodiment of the medical testing device of the present application. The present application provides a medical testing device comprising a device body 2, a reagent kit 1, and an actuator 21.

[0045] The test kit 1 can be interchangeably docked with the device body 2, and a liquid bag containing a reagent can be integrated into the test kit 1. A first fluid passage 11 is provided inside the test kit 1, through which the reagent in the liquid bag or the gas in the external space can flow into the test card 3. Specifically, the first fluid passage 11 has a fluid outlet 111 and at least one fluid inlet 112. The fluid outlet 111 is used to connect to the test card 3, and the fluid inlet 112 is used to connect to the liquid bag and / or the external space. A movable valve body 163 can be provided between the fluid inlet 112 and the fluid outlet 111 of the first fluid passage 11, or at a position where the fluid bag / external space is adjacent to the fluid inlet 112, so as to control the connection or disconnection of the first fluid passage 11 by using the movable valve body 163.

[0046] The actuator 21 can be mounted on the device body 2 and is used to selectively drive the movable valve body 163 to open or close. The actuator 21 mounted on the device body 2 is reusable. Even if the old reagent kit 1 is replaced with a new one, the actuator 21 can still normally drive the movable valve body 163. Optionally, the energy source for the actuator 21 mounted on the device body 2 can be provided by the circuitry of the medical testing device.

[0047] Optionally, the actuator 21 may also be provided on the replaceable reagent box 1. Furthermore, the actuator 21 provided on the reagent box 1 may be powered by an energy storage device such as a battery, or connected to the device body 2 using components such as electrical contacts and wires.

[0048] Optionally, the medical detection device may further include a detection component 22. The detection component 22 may be disposed in the device body 2, and is used to detect a sample using the test card 3 and a reagent introduced into the test card 3.

[0049] The medical testing device provided herein utilizes a first fluid passage 11, independently provided within the test kit 1, to connect the test card 3 with the fluid bag / external space. Furthermore, an actuator 21 actuates a movable valve 163 to control the flow of fluid into the test card 3. Integrating the structure for delivering fluid from the medical testing device to the test card 3 within the test kit 1 eliminates the need for maintaining the fluid passage within the device body 2, reduces the sealing requirements at the interface between the device body 2 and the test kit 1, and effectively improves the stability and durability of the medical testing device.

[0050] Specifically, the test kit 1 provided herein may include a box body 15 and a docking assembly 16. Referring to Figures 2 to 4 , Figure 3 is a schematic cross-sectional view of an embodiment of the medical testing device of the present invention. Figure 4 is an enlarged schematic view of area A in Figure 3 . A first installation space 151 may be formed within the box body 15, with a first opening 152 defined on a side proximal to the actuator 21.

[0051] Optionally, a test card 3 mounting position 155 may be provided in the box body 15 near the detection component 22 in the device body 2, and the fluid outlet 111 of the first fluid passage 11 may be provided in the test card 3 mounting position 155 to achieve docking between the first fluid passage 11 and the test card 3.

[0052] The docking assembly 16 may include a docking body 162 mounted to the first opening 152. The docking body 162 has a cavity 1622, a second opening 1623 communicating with the cavity 1622, and a third opening 1624. The second opening 1623 of the docking body 162 is used to connect to the fluid bag and / or the outside world. When the docking body 162 is mounted to the first opening 152, the third opening 1624 of the docking body 162 connects to the fluid inlet 112 of the first fluid passage 11, thereby connecting the fluid bag / the outside world with the first fluid passage 11, allowing reagents or air to enter the first fluid passage 11.

[0053] Optionally, when assembling the test kit 1 and installing the docking body 162, the liquid bag can be set in the first installation space 151, and the second opening 1623 is located at one end of the docking body 162 close to the first installation space 151. The liquid bag is connected to the first fluid passage 11 by docking with the second opening 1623 of the docking assembly 16.

[0054] Referring to FIG. 4 , the movable valve body 163 can be located within the cavity 1622 of the docking body 162. The movable valve body 163 is configured to move within the cavity 1622 under the drive of the actuator 21. When the movable valve body 163 moves to block the third opening 1624, the third opening 1624 is closed, and the reagent / air entering the cavity 1622 through the second opening 1623 cannot enter the first fluid passage 11 through the third opening 1624. When the movable valve body 163 moves away from the third opening 1624, the third opening 1624 opens, and the reagent / air in the cavity 1622 can enter the first fluid passage 11 through the third opening 1624.

[0055] Optionally, the movable valve body 163 may also be disposed on a side of the third opening 1624 close to the fluid inlet 112 .

[0056] Optionally, in addition to the situation where the movable valve body 163 moves in the cavity 1622 , the movable valve body 163 may also include a deformable structure, and the opening or closing of the first fluid passage 11 is controlled by controlling the deformation of the structure.

[0057] Optionally, the docking assembly 16 may further include an isolating member 164, which blocks the periphery of the third opening 1624 of the docking body 162 near the actuator 21 to isolate the first fluid passage 11 from the device body 2. Referring to Figures 8 to 11, Figure 8 is a schematic structural diagram of the docking assembly and the actuator in an embodiment of the medical detection device of the present application. Figure 9 is a schematic cross-sectional structural diagram of the docking assembly and the actuator in an embodiment of the medical detection device of the present application. Figure 10 is a schematic first cross-sectional structural diagram of the docking assembly in an embodiment of the medical detection device of the present application. Figure 11 is a schematic second cross-sectional structural diagram of the docking assembly in an embodiment of the medical detection device of the present application. The isolating member 164 has a transmission portion 1641, and the actuator 21 can apply force to the movable valve body 163 through the third opening 1624 and the transmission portion 1641, thereby controlling the opening or closing of the first fluid passage 11.

[0058] Specifically, the actuator 21 drives the movable valve body 163 in various ways. For example, it can be controlled by an electrical signal, in which case the transmission part 1641 can pass the electrical signal; or it can be controlled by magnetic force, in which case the transmission part 1641 can pass the magnetic lines; or it can be controlled by mechanical transmission, in which case the transmission part 1641 can transmit the power output by the actuator 21 to the movable valve body 163 when the actuator 21 applies force.

[0059] Optionally, the transmission portion 1641 may be a flexible component. The actuator 21 may include a driving member 211 and an operating member 212. The operating member 212 includes a push rod. When the driving member 211 is in operation, the push rod presses against the transmission portion 1641 from the side of the isolation member 164 facing away from the third opening 1624, causing the push rod to deform. The side of the transmission portion 1641 facing the third opening 1624 presses against the movable valve body 163. As a result, when the transmission portion 1641 is deformed, the movable valve body 163 is pushed to move, allowing the movable valve body 163, which is blocking the third opening 1624, to leave the third opening 1624.

[0060] As shown in Figures 9 to 11 , the transmission portion 1641 of the isolation member 164 can have a variety of profiles. Specifically, when the movable valve body 163 blocks the third opening 1624, the transmission portion 1641 can arch upward toward the actuator 21, supported by the movable valve body 163. The movable valve body 163 applies force against the arched transmission portion 1641, thereby pushing the movable valve body 163 away from the third opening 1624.

[0061] Specifically, the movable valve body 163 can be a movable rod 1631, and a convex ring 1632 is provided on the circumference of the movable rod 1631. The transmission member contacts one end of the movable rod 1631 to push the movable rod 1631 to move. The docking assembly 16 can also include an elastic member 165. The elastic member 165 can be disposed in the cavity 1622 and exert an elastic force on the convex ring 1632 of the movable valve body 163 so that one end of the movable rod 1631 is inserted into the third opening 1624. At the same time, when the end of the movable valve body 163 inserted into the third opening 1624 is not pushed by the push rod, the convex ring 1632 is clamped on the circumference of the third opening 1624 under the action of the elastic member 165, thereby blocking the third opening 1624.

[0062] Refer to Figure 13, which is a schematic diagram of the structure of the docking assembly in one embodiment of the medical detection device of the present application. The docking body 162 may include a packaging cover 1628, which is provided on the side of the docking body 162 where the second opening 1623 is provided. The packaging cover 1628 is provided with a third through-groove 16282 at a position corresponding to the movable rod 1631. The radial dimension of the third through-groove 16282 is smaller than the radial dimension of the convex ring 1632, and the fluid enters the cavity 1622 through the third through-groove 16282. When the docking assembly 16 is produced and assembled, the movable valve body 163 can be placed in the cavity 1622 through the second opening 1623, and the movable valve body 163 is limited by the packaging cover 1628.

[0063] Among them, the moving rod 1631 can be inserted into the third through groove 16282, the third through groove 16282 can be a square hole, and the part of the moving rod 1631 inserted into the third through groove 16282 is a cylindrical rod, and the side length of the square hole is the same as the radial dimension of the cylindrical rod, so that the moving rod 1631 can be limited in the third through groove 16282 while allowing the fluid to pass smoothly.

[0064] Optionally, the packaging cover 1628 includes a third limiting portion 16281 , and the docking body 162 is provided with a fourth limiting portion 1629 near the second opening 1623 . The third limiting portion 16281 and the fourth limiting portion 1629 are snap-fitted to fix the packaging cover 1628 on the docking body 162 .

[0065] Alternatively, the elastic member 165 may be a spring. The spring may be sleeved on the side of the movable rod 1631 away from the third opening 1624 and abutted between the packaging cover 1628 and the protruding ring 1632, thereby making the direction of the elastic force parallel to the axial direction of the movable rod 1631, thereby improving the stability of the movable valve body 163 in controlling the opening or closing of the first fluid passage 11.

[0066] In one embodiment, the movable valve body 163 provided herein may include a movable rod 1631 and a sealing member 1633. The sealing member 1633 is disposed at one end of the movable rod 1631 near the third opening 1624 and is capable of moving within the cavity 1622 in response to the axial movement of the movable rod 1631. The radial dimension of the side surface of the sealing member 1633 facing the third opening 1624 is greater than the radial dimension of the third opening 1624, so that when the sealing member 1633 moves to block the third opening 1624, the first fluid passage 11 is closed.

[0067] Optionally, the sealing member 1633 may be a flexible component, which is sleeved on the outer periphery of the protruding ring 1632. When the movable valve body 163 moves to block the third opening 1624, the flexible sealing member 1633 is deformed, thereby forming a tight seal on the third opening 1624.

[0068] Optionally, the movable rod 1631 can be at least partially inserted into the second opening 1623 and / or the third opening 1624, and the radial dimensions of the second opening 1623 and / or the third opening 1624 are slightly larger than the radial dimensions of the movable rod 1631, so as to limit the movable rod 1631 and prevent the axial change of the movable rod 1631 from affecting the operation of the seal 1633.

[0069] While limiting the movable rod 1631, the inner wall of the second opening 1623 and / or the third opening 1624 can be provided with a drainage groove 1625 for passing reagents or gases. When the seal 1633 leaves the third opening 1624, even if the movable rod 1631 is still inserted in the second opening 1623 and / or the third opening 1624, the drainage groove 1625 can still be used to connect the liquid bag / the external space and the first fluid passage 11.

[0070] Optionally, the reagent kit 1 may further include a flow guide 13. At least a portion of the first fluid passage 11 is disposed within the flow guide 13. At least one fluid inlet 112 is provided at one end of the flow guide 13, with the other end of the flow guide 13 serving as a fluid outlet 111. Alternatively, the other end of the flow guide 13 may be connected to one end of the remaining portion of the first fluid passage 11, with the other end of the remaining portion of the first fluid passage 11 connected to the fluid outlet 111.

[0071] Optionally, the docking assembly 16 may further include a guide hole 1643 adjacent to the third opening 1624. One end of the guide member 13 having the fluid inlet 112 is docked with the guide hole 1643, thereby connecting the fluid bag / external space and the first fluid passage 11.

[0072] As shown in Figure 12, which is a third cross-sectional structural diagram of the test kit in one embodiment of the medical testing device of the present application, the flow guide 13 may further include a flow guide end 131. The test kit 1 may have a through-groove 12a. The flow guide end 131 connects to the remaining portion of the first fluid passage 11 within the test kit 1 through the through-groove 12a, thereby connecting the fluid bag / external space with the first fluid passage 11.

[0073] Optionally, the remaining portion of the first fluid passage 11 may be disposed in the first installation space 151. The guide end 131 is connected to the remaining portion of the first fluid passage 11 in the first installation space 151 through the through groove 12a.

[0074] Optionally, the isolating member 164 may also seal the periphery of the third opening 1624 of the docking body 162 close to the actuator 21 , thereby forming a portion of the first fluid passage 11 between the third opening 1624 of the docking body 162 close to the actuator 21 and the isolating member 164 .

[0075] Furthermore, the isolation member 164 located in the peripheral area of ​​the third opening 1624 may further be formed with a protruding end 1642 , and the guide hole 1643 is formed at the protruding end 1642 .

[0076] Optionally, in order to achieve docking between the flow guide member 13 and the flow guide hole 1643 , the inner diameter of the flow guide hole 1643 may be slightly smaller than the outer diameter of the end of the flow guide member 13 where the fluid inlet 112 is provided.

[0077] Specifically, referring to Figures 9 to 11 , a first groove 1626 may be formed on one side of the third opening 1624 of the docking body 162. The third opening 1624 is located at the bottom of the first groove 1626. The docking assembly 16 also includes a pressure cover 161. Part of the outer contour of the pressure cover 161 is adapted to fit within the first groove 1626. The pressure cover 161 is pressed against the side of the first groove 1626 facing the actuator 21 and is capable of pressing the edge of the isolation member 164 against the bottom of the first groove 1626.

[0078] Optionally, a second groove 1627 connecting the third opening 1624 and the guide hole 1643 can be opened at the bottom of the first groove 1626, and the isolation member 164 covers and seals the second groove 1627, so that a partial fluid passage is formed between the docking body 162 and the isolation member 164 corresponding to the second groove 1627 to guide the fluid passing through the third opening 1624 into the guide hole 1643.

[0079] Furthermore, the side of the gland 161 facing the bottom of the first groove 1626 has a first through-groove 1611 and a second through-groove 1612. The first through-groove 1611 is used to avoid the portion of the isolation member 164 corresponding to the third opening 1624, so that the actuator 21 located on the side of the gland 161 facing away from the third opening 1624 can operate the movable valve body 163 through the first through-groove 1611.

[0080] Optionally, a boss 16411 may be further provided at the position of the transmission portion 1641 corresponding to the third opening 1624 . The boss 16411 protrudes toward the side away from the movable valve body 163 through the first through-groove 1611 so as to abut against the actuator 21 to achieve transmission cooperation.

[0081] Optionally, the second through-groove 1612 is used to avoid the protruding end 1642 provided with the guide hole 1643 , so that the guide member 13 can dock with the guide hole 1643 through the second through-groove 1612 .

[0082] Furthermore, the protruding end 1642 can be a flexible component, and the inner diameter of the guide hole 1643 is smaller than the outer diameter of the guide member 13, so that an interference fit is formed between the protruding end 1642 and the guide member 13 to complete the docking of the fluid inlet 112 of the first fluid passage 11 and the third opening 1624.

[0083] For the flexible protruding end 1642, a second mounting space 1614 communicating with the second through-groove 1612 can be provided on the side of the gland 161 facing the isolation member 164. The radial dimension of the second mounting space 1614 is slightly larger than that of the protruding end 1642, thereby accommodating the protruding end 1642 while also limiting its position. This prevents the protruding end 1642 from deforming under the pressure of the flow guide 13, which could result in a poor seal in the first fluid passage 11.

[0084] Optionally, the opening of the first through-groove 1611 toward the actuator 21 may be provided with a guiding slope to facilitate smooth docking of the actuator 21 with the first through-groove 1611. The opening of the second through-groove 1612 and / or the guide hole 1643 toward the flow guide member 13 may also be provided with a guiding slope to facilitate smooth docking of the flow guide member 13 with the guide hole 1643.

[0085] 12 , a mounting groove 1613 may be further provided on a side of the pressure cover 161 facing away from the third opening 1624 , into which the flow guide 13 is embedded. One end of the flow guide 13 having a fluid inlet 112 is connected to the flow guide hole 1643 through the second through-groove 1612 .

[0086] Specifically, the second through-groove 1612 can be opened at the bottom of the installation groove 1613 , and one end of the guide member 13 provided with the guide inlet directly passes through the second through-groove 1612 from the installation groove 1613 and connects with the guide hole 1643 .

[0087] Referring to Figures 5 to 7, Figure 5 is a schematic diagram of the structure of the reagent box in one embodiment of the medical testing device of the present application. Figure 6 is a schematic diagram of the first cross-sectional structure of the reagent box in one embodiment of the medical testing device of the present application. Figure 7 is a schematic diagram of the second cross-sectional structure of the reagent box in one embodiment of the medical testing device of the present application.

[0088] Furthermore, the edge of the first opening 152 can be provided with one of the sliding rails 1621 and the slider 153, and the docking body 162 can be provided with the other of the sliding rails 1621 and the slider 153, and the sliding rails 1621 and the slider 153 are slidably fitted to install the docking body 162 in the first opening 152.

[0089] 5 , 6 and 7 , the first opening 152 may be an opening with one side open. There are at least two docking assemblies 16 , and all docking bodies 162 are stacked in the first opening 152 along the direction of the slide rail 1621 through the open side of the first opening 152 .

[0090] The docking body 162 closest to the open side of the first opening 152 can be used to connect the external space and the first fluid passage 11 .

[0091] The reagent kit 1 may further include a fixing member 14 , which blocks the open side of the first opening 152 and restricts all the docking bodies 162 installed in the first opening 152 to be located in the first opening 152 .

[0092] In one embodiment, the fixing member 14 may be provided with a first stopper 141 near the box body 15 and / or the first opening 152, and the box body 15 may be provided with a corresponding second stopper 154. The fixing member 14 is fixed to the box body 15 through the cooperation between the first stopper 141 and the second stopper 154, thereby blocking the open side of the first opening 152 and confining the docking body 162 in the first opening 152.

[0093] The present application also provides a medical testing device, comprising a device body 2, a reagent cartridge 1, and an actuator 21. The reagent cartridge 1 is interchangeably docked with the device body 2. The reagent cartridge 1 is provided with a first fluid passage 11, having a fluid outlet 111 and at least one fluid inlet 112. The fluid outlet 111 is configured to connect to a test card 3, and the fluid inlet 112 is configured to connect to a fluid bag / external space. The actuator 21 is connected to the device body 2 and is configured to squeeze the first fluid passage 11 to disconnect the test card 3 from the fluid bag / external space, or to loosen the first fluid passage 11 to connect the test card 3 to the fluid bag / external space.

[0094] Specifically, the position where the first fluid passage 11 is squeezed by the actuator 21 can be set as a flexible component, and the actuator 21 cuts off the first fluid passage 11 by squeezing the flexible component.

[0095] Referring to FIG. 5 , the present application also provides a test kit 1 for use in a medical testing device. The test kit 1 is interchangeably docked with the device body 2 of the medical testing device. The test kit 1 includes an independent first fluid passage 11 having a fluid outlet 111 and at least one fluid inlet 112. The fluid outlet 111 is configured to connect to a testing system, while the fluid inlet 112 is configured to connect to a fluid bag / external space. A movable valve 163 may be provided between the fluid inlet 112 and the fluid outlet 111 of the first fluid passage 11, or adjacent to the fluid inlet 112 in the fluid bag / external space. The movable valve 163 is configured to block or allow fluid in the first fluid passage 11 under the control of the actuator 21.

[0096] The test system may be a test card 3 , or other components or devices that can utilize the fluid in the first fluid passage 11 for testing.

[0097] Optionally, the reagent kit 1 may specifically include a box body 15 and a docking assembly 16. A first installation space 151 is formed inside the box body 15, and the first installation space 151 has a first opening 152 on a side close to the execution assembly 21 of the medical detection device.

[0098] The docking assembly 16 may include a docking body 162. The docking body 162 is mounted to the first opening 152 and has a cavity 1622, a second opening 1623, and a third opening 1624 communicating with the cavity 1622. The second opening 1623 of the docking body 162 is used for docking with the fluid bag / external space. When the docking body 162 is mounted to the first opening 152, the third opening 1624 of the docking body 162 docks with the fluid inlet 112, thereby connecting the fluid bag / external space with the first fluid passage 11.

[0099] Optionally, the movable valve body 163 may be located within the cavity 1622 and may be movable within the cavity 1622 under the drive of the actuator 21. When the movable valve body 163 moves within the cavity 1622 to a position blocking the third opening 1624, the first fluid passage 11 is closed. When the movable valve body 163 leaves the position blocking the third opening 1624, the first fluid passage 11 is opened.

[0100] Optionally, the movable valve body 163 may specifically include a moving rod 1631 and a sealing member 1633. The sealing member 1633 is disposed at one end of the moving rod 1631 close to the third opening 1624 and can move in the cavity 1622 along the axial direction of the moving rod 1631.

[0101] The radial dimension of the surface of the sealing member 1633 facing the third opening 1624 may be larger than the radial dimension of the third opening 1624 , so that the first fluid passage 11 is closed when the sealing member 1633 moves to a position blocking the third opening 1624 .

[0102] Specifically, the movable rod 1631 can be at least partially inserted into the second opening 1623 and / or the third opening 1624. The radial dimensions of the second opening 1623 and / or the third opening 1624 are slightly larger than the radial dimensions of the movable rod 1631, thereby utilizing the second opening 1623 and / or the third opening 1624 to limit the axial position of the movable rod 1631. Furthermore, a drainage groove 1625 is defined on the inner wall of the second opening 1623 and / or the third opening 1624, such that when the sealing member 1633 leaves the position blocking the third opening 1624, at least the fluid bag and the first fluid passage 11 can be connected through the drainage groove 1625.

[0103] As shown in Figures 1 and 2, the present application also proposes a test kit 1, which includes a docking slot 103 and a sampling component 104. The docking slot 103 includes a sampling component docking interface 1032. One end of the sampling component 104 is connected to the test card, and the other end can be selectively docked with the sampling component docking interface 1032. The sample input from the outside can be input into the test card through the sampling component 104. The test kit 1 can be provided with a first infusion line 101, which is used to pass a cleaning liquid into the docking slot 103 of the test kit 1 to clean the outer surface of the sampling component 104 and the docking slot 103 when the sampling component 104 is docked with the sampling component docking interface 1032.

[0104] The reagent kit 1 is interchangeably docked with the device body 2. A cleaning solution package 12 may be provided in the reagent kit 1. A fluidics assembly 4 is provided on the reagent kit 1, and a second fluid passage 41 is provided in the fluidics assembly 4. The second fluid passage 41 may have a first fluid outlet 411 and at least two first fluid inlets 412. The first fluid outlet 411 is configured to connect to the docking slot 103 of the reagent kit 1 via the first infusion line 101. The at least two first fluid inlets 412 are configured to connect the cleaning solution package 12 to the outside world and selectively connect to the first fluid outlet 411.

[0105] Optionally, the fluid outlet 111 of the first fluid passage 11 is disposed at the end of the sampling assembly 104 connected to the test card. The first fluid passage 11 is at least partially disposed within the sampling assembly 104. The remaining portion of the first fluid passage 11 near the fluid inlet 112 can be connected to the portion of the first fluid passage 11 within the sampling assembly 104 via the sampling assembly docking port 1032 of the docking slot 103. When the sampling assembly docking port 1032 is docked with the other end of the sampling assembly 104, the first fluid passage 11 connects the fluid bag / external space to the test card.

[0106] By using the mutually independent second fluid passage 41 and first fluid passage 11, a fluid passage can be formed only in the reagent kit 1, thereby eliminating the maintenance cost of the fluid passage in the device body and improving the stability of the medical detection device; and because the first fluid inlet 412 can be connected to the external space, the gas-liquid passage of the input docking groove 103 can be integrated into one, without the need to set up an additional air inlet passage, which can simplify the structure of the fluid passage in the reagent kit 1, and further simplify the structure of the medical detection device, reduce production costs, and improve the availability of the device.

[0107] Specifically, as shown in Figures 1, 2, and 14-18, the second fluid passage 41 has a first fluid outlet 411 and at least two first fluid inlets 412. The first fluid outlet 411 is used to connect to the docking slot 103 of the reagent kit 1 through the first infusion line 101. The at least two first fluid inlets 412 are respectively used to connect to the cleaning solution package 12 and the outside world, and are selectively connected to the first fluid outlet 411. In other words, when the first fluid inlet 412 of the fluidics assembly 4 connected to the cleaning solution package 12 is connected to the first fluid outlet 411, the first fluid inlet 412 of the fluidics assembly 4 connected to the outside world is disconnected from the first fluid outlet 411, and the cleaning solution package 12 is transported in the first infusion line 101. When the first fluid inlet 412 of the fluid control component 4 connected to the external space is connected to the first fluid outlet 411, the first fluid inlet 412 of the fluid control component 4 connected to the cleaning liquid bag 12 is not connected to the first fluid outlet 411, and the gas passed into the first infusion line 101 can be used to pass all the cleaning liquid that stays or remains in the first infusion line 101 into the docking groove 103.

[0108] As shown in Figures 14 and 15, the fluid control assembly 4 may include a cavity 6 and a first movable valve body 7. A second fluid passage 41 is formed in the cavity 6, and the first movable valve body 7 is used to control whether the first fluid outlet 411 is connected to the first fluid inlet 412 connected to the cleaning liquid bag 12 or the first fluid inlet 412 connected to the external space.

[0109] Specifically, referring to Figures 17 to 20, the cavity 6 has a first cavity 615 and a fourth opening 611, a fifth opening 612, a sixth opening 613 and a seventh opening 624 connected to the first cavity 615. The first cavity 615 serves as at least a part of the second fluid passage 41, the fourth opening 611 serves as a first fluid inlet 412 for docking with the cleaning fluid bag, the fifth opening 612 serves as another first fluid inlet 412 for communicating with the external space, the sixth opening 613 serves as a first fluid outlet 411 for connecting to the docking slot 103 of the reagent kit 1 through the first infusion line 101, and the seventh opening 624 serves as an external force operation window.

[0110] Referring to Figures 19 to 22, the fluid control assembly 4 further includes a first movable valve body 7, which is positioned within the first cavity 615. The first movable valve body 7 is configured to respond to external forces and move from a first position within the first cavity 615 to a second position. When the first movable valve body 7 is in the first position, the fifth opening 612 and the sixth opening 613 are in communication, while the fourth opening 611 and the sixth opening 613 are blocked. When the first movable valve body 7 is in the second position, the fourth opening 611 and the sixth opening 613 are in communication, while the fifth opening 612 and the sixth opening 613 are blocked. In other words, when the first movable valve body 7 is in the first position, the first fluid outlet 411 is disconnected from the first fluid inlet 412 connected to the cleaning fluid bag. In this case, the fluid control assembly 4 is configured to deliver gas to the first infusion path 101. When the first movable valve body 7 is in the second position, the first fluid outlet 411 is disconnected from the first fluid inlet 412 connected to the outside world. In this case, the fluid control assembly 4 is configured to deliver cleaning fluid from the cleaning fluid bag to the first infusion path 101.

[0111] Optionally, referring to FIG. 2 , the main body 10 of the medical testing device may include an actuator 21. The actuator 21 may be mounted on the main body 10 and configured to apply an external force to the first movable valve body 7, thereby selectively actuating the first movable valve body 7 between the first and second positions. The actuator 21 mounted on the main body 10 is reusable; even if an old reagent kit 1 is replaced with a new one, the actuator 21 can still function to actuate the first movable valve body 7. Optionally, the actuator 21 mounted on the main body 10 may be powered by the circuitry of the medical testing device.

[0112] Optionally, the actuator 21 may also be provided on the replaceable reagent box 1. Furthermore, the actuator 21 provided on the reagent box 1 may be powered by an energy storage device such as a battery, or connected to the main body 10 using components such as electrical contacts and wires.

[0113] Optionally, referring to Figure 19, the cavity 6 may include a liquid channel body 61 and a bracket 62. The liquid channel body 61 has a receiving groove 614 for accommodating the first movable valve body 7, and the fourth opening 611, the fifth opening 612, and the sixth opening 613 are all arranged on the liquid channel body 61. The first movable valve body 7 moves in the receiving groove 614. When the first movable valve body 7 moves to the second position, the fifth opening 612 and the sixth opening 613 are blocked. At this time, the cleaning liquid flows in the receiving groove 614, and since the fifth opening 612 connecting the receiving groove 614 to the external space is blocked, the cleaning liquid will not flow out from the fifth opening 612, thereby improving the airtightness of the fluid control component 4.

[0114] As shown in Figures 15 to 22, the second fluid passage 41 may include a first sub-passage, a second sub-passage and a third sub-passage, one end of the first sub-passage is a first fluid inlet 412, one end of the second sub-passage is another first fluid inlet 412, one end of the third sub-passage is a first fluid outlet 411, and the other ends of the first sub-passage and the second sub-passage are selectively connected to the other end of the third sub-passage by the movement of the first movable valve body 7.

[0115] As shown in Figure 19, when the first movable valve body 7 is in the first position, the other end of the second sub-passage is connected to the other end of the third sub-passage, and the other end of the first sub-passage and the other end of the third sub-passage are blocked, so that the fifth opening 612 and the sixth opening 613 connected to the external space are connected, and the fluid control component 4 delivers air to the first infusion path 101.

[0116] As shown in FIG22 , when the first movable valve body 7 is in the second position, the other end of the first sub-channel is connected to the other end of the third sub-channel, while the other end of the second sub-channel is blocked from the other end of the third sub-channel. Thus, the fourth opening 611 and the sixth opening 613 connected to the cleaning fluid bag are connected, and the fluid control assembly 4 delivers cleaning fluid into the first infusion path 101. In this way, the fluid control assembly 4 can control whether it delivers gas or cleaning fluid into the first infusion path 101 by moving the first movable valve body 7, thereby smoothly delivering the cleaning fluid into the docking tank 103. When delivering gas, any cleaning fluid remaining in the fluid path can be pushed to the wastewater pump.

[0117] Optionally, referring to Figures 19 and 20, the cavity 6 further includes a bracket 62, which covers the opening of the receiving groove 614 of the liquid channel body 61 to form a first cavity 615. The first movable valve body 7 is located within the first cavity 615. By forming the first cavity 615, the first movable valve body 7 can move within the receiving groove 614, thereby selectively connecting the fourth opening 611 and the sixth opening 613, or the fifth opening 612 and the sixth opening 613.

[0118] To allow the first movable valve body 7 to abut the actuator 21 and move in response to external forces, the bracket 62 has a seventh opening 624 that communicates with the accommodating groove 614. This allows the end of the movable valve body 7 located outside the seventh opening 624 to receive external forces from the actuator 21, allowing the first movable valve body 7 to move within the accommodating groove 614.

[0119] Optionally, referring to Figures 19 and 22, the first movable valve body 7 moves in the accommodating groove 614 toward or away from the bracket 62, and the fourth opening 611, one of the fifth opening 612, and the sixth opening 613 are all disposed on the side of the liquid channel body 61 near the bracket 62. The fourth opening 611 and the sixth opening 613 shown in Figure 20 are disposed on the side of the liquid channel body 61 near the bracket 62. In some embodiments, the positions of the fourth opening 611 and the fifth opening 612 can be interchanged, i.e., the opening originally intended for gas flow can be replaced with an opening intended for liquid flow, in which case the fifth opening 612 and the sixth opening 613 are disposed on the side of the liquid channel body 61 near the bracket 62.

[0120] Optionally, referring to Figures 19 and 17 , since the seventh opening 624 of the bracket 62 is connected to the receiving groove 614, the cavity 6 may include a first isolating member 64 to prevent the cleaning fluid from flowing out of outlets other than the first fluid outlet 411 into other components of the medical testing device, such as from the fluidics assembly 4 and dripping onto the housing of the medical testing device. The first isolating member 64 is disposed outside the seventh opening 624 on the side of the bracket 62 facing away from the fluid channel body 61, and surrounds the area outside the cavity 6 having the seventh opening 624. In this manner, the cleaning fluid input from the first fluid inlet 412 is isolated by the first isolating member 64 within the fluidics assembly 4, allowing it to flow out through the first fluid outlet 411.

[0121] Optionally, in the fluidic control assembly 4, a second fluid passage 41 is formed between the liquid channel body 61, the bracket 62, and the first isolating member 64. Specifically, as shown in Figures 15 and 17, the area of ​​the bracket 62 surrounded by the first isolating member 64 has a through hole 623 and a first connecting groove 621. The two ends of the first connecting groove 621 respectively connect one end of the through hole 623 and the seventh opening 624, and the other end of the through hole 623 connects to the fourth opening 611.

[0122] As shown in Figures 23 and 24, the side of the bracket 62 that presses against the liquid channel body 61 has a second connecting groove 622, with both ends of the second connecting groove 622 connected to the receiving groove 614 and the sixth opening 613. Thus, the cleaning fluid entering from the first fluid inlet 412 passes through the fourth opening 611 of the liquid channel body 61, then flows through the through-hole 623 and the first connecting groove 621, and finally flows from the seventh opening 624 to the receiving groove 614. The receiving groove 614 is connected to the second connecting groove 622 connected to the sixth opening 613. Therefore, the cleaning fluid finally flows from the receiving groove 614 through the second connecting groove 622 and out of the first fluid outlet 411 through the sixth opening 613.

[0123] Specifically, when the first movable valve body 7 moves toward the bracket 62 to the first position, the first movable valve body 7 leaves the fifth opening 612 and blocks the seventh opening 624 to block the first sub-passage formed by the fourth opening 611, the through hole 623, the first connecting groove 621, and the sixth opening 613, and the first movable valve body 7 leaves the fifth opening 612 to open the second sub-passage formed by the fifth opening 612 and the accommodating groove 614.

[0124] When the first movable valve body 7 moves to the second position away from the bracket 62, the first movable valve body 7 leaves the seventh opening 624 and blocks the fifth opening 612 to open the first sub-passage formed by the fourth opening 611, the through hole 623, the first connecting groove 621, and the sixth opening 613, and blocks the second sub-passage formed by the fifth opening 612 and the accommodating groove 614.

[0125] When the first movable valve body 7 is in the first position, it blocks the seventh opening 624, preventing cleaning fluid from flowing into the receiving groove 614 connected to the seventh opening 624. Consequently, when air is extracted, cleaning fluid will not be drawn from the cleaning fluid bag 12. This improves the usability of the fluid control assembly 4. Furthermore, when the first movable valve body 7 is in the second position, it blocks the fifth opening 612. Therefore, even if the seventh opening 624 is connected to the second connecting groove 622, which in turn is connected to the receiving groove 614, cleaning fluid may flow to the vicinity of the fifth opening 612. However, at this time, the fifth opening 612 is blocked by the first movable valve body 7. Therefore, even if cleaning fluid flows to the vicinity of the fifth opening 612, leakage will not occur, thereby improving the airtightness of the fluid control assembly 4. In this way, the fluid control assembly 4 achieves multiple functions through a simple structure, resulting in high usability.

[0126] Optionally, when the first movable valve body 7 is in the first position, the fifth opening 612 and the sixth opening 613 are connected via the accommodating groove 614 and the second connecting groove 622. To allow gas or cleaning liquid to flow from the fifth opening 612 to the sixth opening 613, the diameter of the first movable valve body 7 can be smaller than the diameter of the accommodating groove 614, or the first movable valve body 7 can have a third axial connecting groove on its side to connect the fifth opening 612 and the second connecting groove 622 in the first position.

[0127] Alternatively, referring to Figure 25, the first movable valve body 7 can be a rod-shaped movable member having a first convex ring 73. In order to allow gas or cleaning liquid to flow from the fifth opening 612 to the sixth opening 613, the radial dimension of the first convex ring 73 can be smaller than the diameter of the accommodating groove 614 and larger than the size of the seventh opening 624. In this way, the first convex ring 73 can be used to block the seventh opening 624. In other words, when the rod-shaped movable member is in the first position, the first convex ring 73, whose radial dimension is larger than the size of the seventh opening 624, can block the seventh opening 624.

[0128] Optionally, how to determine whether the first protruding ring 73 of the first movable valve body 7 can block the seventh opening 624, and how to reset the first movable valve body 7 from the second position to the first position after the first movable valve body 7 is moved from the first position to the second position by an external force, can be achieved by adopting the following embodiments. As shown in Figure 19, the fluid control component 4 may include a first elastic member 8. The first elastic member 8 is located in the cavity 615 and applies elastic force to the first protruding ring 73 of the first movable valve body 7 so that one end of the rod-shaped movable member passes through the seventh opening 624. At the same time, when the end of the first movable valve body 7 inserted into the seventh opening 624 is not subjected to external force, the first protruding ring 73 is clamped around the seventh opening 624 to block the seventh opening 624; when the first movable valve body 7 is subjected to external force, the first elastic member 8 contracts, and at the same time, the side of the first protruding ring 73 close to the first elastic member 8 opens the seventh opening 624 and blocks the fifth opening 612. Optionally, the first elastic member 8 may be a spring.

[0129] For example, the first elastic member 8 can be disposed at an end of the first movable valve body 7 away from the seventh opening 624 and can exert an elastic force on the first protruding ring 73 of the first movable valve body 7, so that one end of the rod-shaped movable member passes through the seventh opening 624. Simultaneously, when no external force is applied to the end of the first movable valve body 7 inserted into the seventh opening 624, the first protruding ring 73 is secured around the seventh opening 624 to block the seventh opening 624. When the first movable valve body 7 is subjected to an external force, the elastic member in contact with the first protruding ring 73 contracts, causing the first movable valve body 7 to also move under the external force, thereby opening the seventh opening 624. Simultaneously, the side of the first protruding ring 73 closer to the first elastic member 8 blocks the fifth opening 612. In this manner, the first movable valve body 7 can selectively open or block the seventh opening 624, thereby selectively allowing the fluid control assembly 4 to selectively introduce cleaning fluid from the cleaning fluid bag 12 or air from the outside into the first infusion path 101.

[0130] Optionally, to enhance the sealing of the fifth opening 612 by the first movable valve body 7 when the first movable valve body 7 is in the first position, a sealing gasket may be provided on the first movable valve body 7. Referring to Figures 26 and 27 , the first movable valve body 7 may include a first sealing gasket 71 disposed at one end of the first movable valve body 7 proximal to the fifth opening 612. The radial dimension of the surface of the first sealing gasket 71 facing the fifth opening 612 is greater than the inner diameter of the fifth opening 612, thereby sealing the fifth opening 612 when the first movable valve body 7 is subjected to an external force.

[0131] Optionally, the first sealing gasket 71 may be a flexible component, sleeved on the outer circumference of the first protruding ring 73. When the first movable valve body 7 moves to block the fifth opening 612, the flexible sealing gasket is deformed, thereby forming a tight blockage for the fifth opening 612.

[0132] Optionally, the radial dimension of the first sealing gasket 71 is smaller than the diameter of the accommodating groove 614 , so that when the first movable valve body 7 is in the first position, a gap is formed between the first sealing gasket 71 and the inner wall of the accommodating groove 614 to connect the fifth opening 612 and the second communicating groove 622 .

[0133] Optionally, referring to FIG. 19 , a second limiting ring 712 is provided on the circumferential side of the rod-shaped movable member on which the first sealing gasket 71 is sleeved, and the second sealing gasket 72 wraps the second limiting ring 712 .

[0134] Optionally, the side of the first sealing gasket 71 may have an axial fifth communication groove, so that the air flowing in from the fifth opening 612 can be connected to the second communication groove 622 through the fifth communication groove, and can flow out of the fluid control component 4 from the first fluid outlet 411.

[0135] Optionally, one end of the rod-shaped movable member having the first sealing gasket 71 extends beyond the first sealing gasket 71 and is inserted into the fifth opening 612. In some embodiments, when the first movable valve body 7 is in the second position, the one end of the rod-shaped movable member having the first sealing gasket 71 extends beyond the first sealing gasket 71 and is inserted into the fifth opening 612. In this way, while the first sealing gasket 71 blocks the fifth opening 612, the one end of the rod-shaped movable member having the first sealing gasket 71 can also block the air inlet 92, thereby enhancing the effect of blocking the fifth opening 612.

[0136] Alternatively, the radial dimension of one end of the rod-shaped moving member near the fifth opening 612 is smaller than the radial dimension of the fifth opening 612, so that fluid can pass through while the moving member is restricted. For example, the fifth opening 612 can be a circular hole, and the cross-section of the rod-shaped moving member in the radial direction can be a square, and the length of the line connecting the diagonals of the square is the same as the diameter of the circular hole of the fifth opening 612. In this way, fluid can pass through while the rod-shaped moving member is restricted.

[0137] Optionally, to enhance the effect of the first movable valve body 7 in blocking the seventh opening 624 , the first protruding ring 73 includes a second sealing gasket 72 at least located on the surface of the first protruding ring 73 .

[0138] In order to ensure that when the second sealing gasket 72 blocks the seventh opening 624, the air flowing in from the other first fluid inlet 412 can flow out from the first fluid outlet 411, the radial dimension of the second sealing gasket 72 is smaller than the diameter of the accommodating groove 614 or the side of the second sealing gasket 72 has an axial fourth connecting groove, and a gap is formed between the second sealing gasket 72 and the inner wall of the accommodating groove 614 to connect the fifth opening 612 and the second connecting groove 622.

[0139] Optionally, the second sealing gasket 72 is sleeved on the rod-shaped movable member, and the circumferential side of the rod-shaped movable member on which the second sealing gasket 72 is sleeved is provided with a first limiting ring 721, and the second sealing gasket 72 wraps the first limiting ring 721. By providing the first limiting ring 721 on the circumferential side of the rod-shaped movable member on which the second sealing gasket 72 is sleeved, and the second sealing gasket 72 wraps the first limiting ring 721, the position of the second sealing gasket 72 on the rod-shaped movable member can be fixed, thereby preventing the position of the second sealing gasket 72 on the rod-shaped movable member from being displaced, which would result in the second sealing gasket 72 being unable to completely block the seventh opening 624 when the first movable valve body 7 is in the first position state, thereby improving the usability and working effect of the fluid control component 4.

[0140] Optionally, referring to FIG. 19 , the area of ​​the first isolation member 64 corresponding to the seventh opening 624 is the first transmission portion 641 . The first transmission portion 641 is configured to receive force from the outside of the first isolation member 64 and deform under the force to contact the first movable valve body 7 .

[0141] Optionally, the first transmission portion 641 is an elastic component. When a force is applied to the side of the first transmission portion 641 facing away from the seventh opening 624, the first transmission portion 641 deforms toward the seventh opening 624, thereby contacting and pushing the first movable valve body 7 to move, causing the first movable valve body 7, which was blocking the seventh opening 624, to move away from the seventh opening 624. After the external force is released, the first transmission portion 641 elastically recovers and is spaced apart from the seventh opening 624. For example, the first isolation member 64 may be silicone.

[0142] Optionally, referring to FIG. 26 , the bracket 62 has a third groove 625 on a side proximal to the first isolating member 64. The first isolating member 64 covers the bottom of the third groove 625. The fluid control assembly 4 further includes a first pressing cap 9 whose shape matches the third groove 625. The first pressing cap 9 is pressed into the third groove 625 and presses the edge of the first isolating member 64 against the bottom of the third groove 625. The first pressing cap 9 has a fourth through-groove 91 on the side facing the seventh opening 624. The fourth through-groove 91 avoids the portion of the first isolating member 64 corresponding to the seventh opening 624. External force operates the first movable valve body 7 through the fourth through-groove 91. By pressing the first pressing cap 9 into the third groove 625 and pressing the edge of the first isolating member 64 against the bottom of the third groove 625, the structural tightness of the fluid control assembly 4 can be improved.

[0143] For example, the actuator 21 abuts against the first transmission part 641 through the fourth through groove 91 , and the actuator 21 applies a force to the first transmission part 641 , causing the first transmission part 641 to deform, and the first movable valve body 7 to move, so that the first movable valve body 7 that blocks the seventh opening 624 leaves the seventh opening 624 .

[0144] Optionally, to eliminate the need for an additional air inlet channel outside the fluidic control assembly 4, an air inlet channel 616 can be provided within the fluidic control assembly 4's fluidic control assembly main body 61.

One end 6161 of the air inlet channel is connected to the air inlet 92, and the other end 6162 of the air inlet channel is connected to the fifth opening 612. The air inlet channel 616 sequentially passes through the first gland 9, the first isolator 64, the bracket 62, and the fluidic control assembly main body 61.

[0145] Specifically, the bracket 62 has a first through-hole 626, the first isolating member 64 has a second through-hole 642, and one end 6161 of the air inlet channel 616 is sequentially connected to the first through-hole 626, while the second through-hole 642 is connected to the air inlet 92. The air inlet 92 can be disposed on the periphery of the reagent container 1, that is, an independent air inlet 92 can be disposed on the first gland 9 for supplying air to the fluidics assembly 4. Thus, the air inlet channel 616 can sequentially penetrate the first gland 9, the first isolating member 64, the bracket 62, and the fluidic channel body 61, ultimately connecting to the fifth opening 612 through the fluidic channel body 61.

[0146] Optionally, as shown in Figures 27 and 19, the liquid channel body 61 may include a accommodating tank body 617 and a cover body 618, the accommodating tank body 617 has a parallel first through groove 6171 and a second through groove 6172, the cover body 618 is arranged on the same side of the first through groove 6171 and the second through groove 6172, and a fifth connecting groove 6175 is provided between the cover body 618 and the accommodating tank body 617, connecting the first through groove 6171 and the second through groove 6172, the first through groove 6171 and the cover body 618 form the accommodating tank 614, and the fifth connecting groove 6175 and the second through groove 6172 form the air intake channel 616.

[0147] By providing the air inlet channel 616 in the fluidic control component 4 , the air channel and the liquid channel can be integrated inside the fluidic control component 4 without providing an additional air inlet channel to connect the fluidic control component 4 with the external space.

[0148] 26 and 27 , the cavity 6 may include a third sealing gasket 63 for guiding the liquid flowing in the fluidic control component 4 and improving the sealing performance of the fluidic control component 4 to reduce leakage. Specifically, the third sealing gasket 63 may have two protrusions 631 . An extension portion 619 extends laterally from the opening edge of the accommodating groove 614 of the liquid channel body 61. The extension portion 619 has a locking groove 6191 on the side facing the bracket 62. The accommodating groove 614 is opened at the bottom of the locking groove 6191. The third sealing gasket 63 is locked in the locking groove 6191. The third sealing gasket 63 is provided with a fifth opening 635. The fifth opening 635 connects the accommodating groove 614 and the seventh opening 624. The extension portion 619 has a through-opening 6192 corresponding to the protrusion 631. The protrusion 631 is inserted into the through-opening 6192. The protrusion 631 has a through-hole 6311. The through-hole 6311 of one protrusion 631 serves as the fourth opening 611 at one end facing away from the third sealing gasket 63, and the other end connects the fourth opening 611 and the through-hole 623. The through-hole 6311 of the other protrusion 631 serves as the sixth opening 613 at one end facing away from the third sealing gasket 63, and the other end connects to the second connecting groove 622.

[0149] Optionally, referring to FIG12 , the through-groove 12a can be specifically provided in the fluidic control assembly 4. By providing the through-groove 12a in the fluidic control assembly 4, the flow guide 13 passes through the through-groove 12a of the fluidic control assembly 4, avoiding other components in the fluidic control assembly 4, and connects to the sampling assembly docking port 1032 in the docking slot 103. This can improve the structural compactness of the device and fully utilize the space of the device.
