Description

Technical Field

[0001] This application relates to the field of analytical instruments, and particularly to fluid control components and medical detection devices. Background Art

[0002] Common medical detection devices generally have a reagent pack, a sampling component for obtaining samples, and a docking groove for docking with the sampling component. The outer surface of the sampling component that has just collected a biochemical sample may be contaminated with the sample, and it may contaminate the inside of the docking groove when docking with the docking groove. Therefore, medical detection devices usually also come with valves, which can not only control the liquid in the reagent pack to enter the sampling component, but also control the cleaning liquid to clean the outer surface of the sampling component.

[0003] Due to numerous tasks to be completed, the internal channels of commonly used valves are complex. In order to facilitate separating the liquid leading to the inside of the sampling component and the liquid for cleaning the sampling component in the docking groove, the valves usually set these two channels as independent channels. Therefore, there are many redundant and unnecessary structures on the valves, and these structures will also affect the volume of the valves, reducing the usability of the valves.

[0032] In order to make the above-mentioned purposes, 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 is to 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 structures related to the present application are shown in the accompanying drawings, rather than all structures. 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.

[0033] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "provided with" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or devices.

[0034] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] With the increasing progress of analysis technology, the sampling component of a medical detection device can be used to obtain samples and / or other reagents, and then the sampling component is docked with the docking slot of the medical detection device, so that the samples in the sampling component can be input into the detection component of the medical detection device through the pipeline in the docking slot. However, after the sampling component collects the samples, the outer surface of the sampling component may have residual samples, or the samples in the sampling component may drip before docking, which will affect the cleanliness of the docking slot. Therefore, it is necessary to clean the outer wall of the sampling component before the sampling component is docked with the docking slot. Therefore, a medical detection device usually also comes with a fluid control component to control the cleaning liquid to clean the outer surface of the sampling component.

[0036] And since in a medical detection device, it is necessary to introduce liquid into the sampling component and introduce liquid for cleaning the sampling component into the docking slot, these two channels can be set as independent channels in the medical detection device. How to set these two channels as independent channels with high efficiency and reduce redundant structures is an urgent problem to be solved. Specifically, the second fluid control component for introducing liquid into the sampling component can control whether the fluid conveyed in the channel is gas or liquid. When the second fluid control component closes the gas channel and connects the liquid channel, the pipeline between the second fluid control component and the detection component conveys liquid. To prevent the liquid in the channel from staying in the pipeline and ensure that all the liquid reaches the detection component, the liquid channel can be closed and the gas channel can be opened to push all the liquid in the pipeline to the detection component by air. Similarly, the second fluid control component for introducing liquid for cleaning the sampling component into the docking slot can also control whether the fluid conveyed in the channel is gas or liquid.

[0037] Since air needs to be introduced into both the first flow control component and the second flow control component, the first flow control component and the second flow control component need to be connected to the air intake passage. However, adding an additional air intake passage in the medical detection component will make the internal structure of the device complex. To improve or solve the above technical problems, the present application proposes at least the following embodiments.

[0038] As Figures 1 to 5 shown, the present application proposes a medical detection device, which includes a main body 10, a first flow control component 4, and a second flow control component 5. Among them, the first flow control component 4 is used to introduce a cleaning liquid for cleaning the sampling component into the docking slot, and the second flow control component 5 is used to introduce a reagent into the sampling component and send it to the detection component. A first infusion path 101 and a second infusion path 102 are formed in the main body 10. The first infusion path 101 is used to introduce a cleaning liquid into the docking slot of the reagent kit 1. The second infusion path 102 is used to introduce a reagent into the test card 3 through the sampling component of the reagent kit 1. The test card 3 is the above-mentioned detection component. The first infusion path 101 and the second infusion path 102 are two independent channels as described above.

[0039] As previously mentioned, both the first flow control component 4 and the second flow control component 5 can control whether the fluid transported in the first infusion path 101 and the second infusion path 102 is a gas or a liquid. Therefore, both the first flow control component 4 and the second flow control component 5 need to be provided with an inlet to connect the external space and the liquid space.

[0040] Specifically, referring to Figure 1 and Figure 5 , the first flow control component 4 is provided with a first fluid passage 41, and the first 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 the docking slot of the reagent kit 1 through the first infusion path 101. The at least two first fluid inlets 412 are respectively used to connect the cleaning liquid package 12 and the external space, and selectively connect to the first fluid outlet 411. In this way, it is possible to control whether the fluid transported in the first infusion path 101 is a gas or a liquid through the first flow control component 4, so as to realize introducing the cleaning liquid into the docking slot.

[0041] Similarly, referring to Figure 2 and Figure 1 , the second flow control component 5 is provided with a second fluid passage 51, and the second fluid passage 51 has a second fluid outlet 512 and at least one second fluid inlet 511. The second fluid outlet 512 is connected to the sampling component interface in the docking slot through the second infusion path 102. The second fluid inlet 511 is used to connect the liquid bag / external space. After the sampling component is docked with the sampling component interface, the second infusion path 102 is formed. In this way, it is possible to control whether the gas or liquid transported in the second infusion path 102 through the second flow control component 5, so as to realize introducing the reagent in the liquid bag into the test card 3.

[0042] By providing a first fluid passage 41 in the first fluid control component 4 and a second fluid passage 51 in the second fluid control component 5, independent channels can be formed in the medical detection device. Since the first fluid inlet 412 of the first fluid control component 4 can be connected to the external space, the gas-liquid channels can be integrated within the first fluid control component 4 without the need to provide an additional air inlet channel, thereby simplifying the structure of the fluid control component and further simplifying the structure of the medical detection device, improving the usability of the device.

[0043] The first fluid control component 4 will be described in detail below.

[0044] As Figures 1 to 7 shown, the present application provides a first fluid control component 4 for a medical detection device. In this medical detection device, there is a first infusion line 101 for introducing a cleaning solution into the docking slot in the reagent kit 1 to rinse the sampling component in the docking slot. The first fluid control component 4 is provided with a first fluid passage 41 having 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 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 external space and selectively connect to the first fluid outlet 411. That is to say, when the first fluid inlet 412 of the first fluid control component 4 connecting the cleaning solution package 12 is connected to the first fluid outlet 411, the first fluid inlet 412 of the first fluid control component 4 connecting the external space is not in communication with 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 first fluid control component 4 connecting the external space is connected to the first fluid outlet 411, the first fluid inlet 412 of the first fluid control component 4 connecting the cleaning solution package 12 is not in communication with the first fluid outlet 411, and the gas introduced into the first infusion line 101 can be used to flush all the cleaning solution remaining or staying in the first infusion line 101 into the docking slot.

[0045] As Figure 3 and Figure 4 shown, the first fluid control component 4 includes a cavity 6 and a movable valve body 7. The cavity 6 forms the first fluid passage 41 therein, and the movable valve body 7 is used to control whether the first fluid inlet 412 connecting the cleaning solution package 12 or the first fluid inlet 412 connecting the external space is connected to the first fluid outlet 411.

[0046] Specifically, referring to Figures 5 to 9, the cavity 6 has a cavity 615 and a first opening 611, a second opening 612, a third opening 613, and a fourth opening 624 that communicate with the cavity 615. The cavity 615 serves as at least a part of the first fluid passage 41. The first opening 611 serves as a first fluid inlet 412 for docking with a cleaning solution bag. The second opening 612 serves as another first fluid inlet 412 for communicating with the external space. The third opening 613 serves as a first fluid outlet 411 for connecting to the docking groove of the reagent kit 1 through the first infusion line 101. The fourth opening 624 serves as an external force operation window.

[0047] Refer to Figures 8 to 11 , the first fluid control assembly 4 further includes a movable valve body 7, which is located in the cavity 615. The movable valve body 7 is used to receive the action of an external force and move from the first position in the cavity 615 to the second position. When the movable valve body 7 is in the first position, the second opening 612 and the third opening 613 are in communication, and the first opening 611 and the third opening 613 are blocked. When the movable valve body 7 is in the second position, the first opening 611 and the third opening 613 are in communication, and the second opening 612 and the third opening 613 are blocked. That is to say, when the movable valve body 7 is in the first position, the first fluid outlet 411 and the first fluid inlet 412 connected to the cleaning solution bag are not in communication. At this time, the first fluid control assembly 4 is used to convey gas into the first infusion line 101. When the movable valve body 7 is in the second position, the first fluid outlet 411 and the other first fluid inlet 412 connected to the external space are not in communication. At this time, the first fluid control assembly 4 is used to convey the cleaning solution in the cleaning solution bag into the first infusion line 101.

[0048] Optionally, refer to Figure 2 , the main body 10 of the medical detection device may include an execution assembly 21. The execution assembly 21 can be installed on the main body 10 and is used to apply an external force to the movable valve body 7, that is, to selectively drive the movable valve body 7 to be in the first position or the second position. The execution assembly 21 provided on the main body 10 can be reused. Even if the old reagent kit 1 is replaced with a new reagent kit 1, the execution assembly 21 can still normally perform the work of driving the movable valve body 7. Optionally, the energy source of the execution assembly 21 installed on the main body 10 can be provided by the circuit of the medical detection device.

[0049] Optionally, the execution assembly 21 can also be provided on the replaceable reagent kit 1. Further, the execution assembly 21 provided on the reagent kit 1 can be powered by an energy storage device such as a battery, or can be connected to the main body 10 by using components such as electrical contacts and wires.

[0050] Optionally, refer to Figure 8, the cavity 6 may include a liquid passage main body 61 and a bracket 62. The liquid passage main body 61 has a receiving groove 614 for receiving the movable valve body 7, and the first opening 611, the second opening 612, and the third opening 613 are all provided on the liquid passage main body 61. The movable valve body 7 moves within the receiving groove 614. When the movable valve body 7 moves to the second position, that is, the second opening 612 and the third opening 613 are blocked. At this time, the cleaning liquid flows within the receiving groove 614, and since the second opening 612 communicating with the outside space of the receiving groove 614 is blocked, the cleaning liquid will not flow out from the second opening 612, thereby improving the tightness of the first fluid control assembly 4.

[0051] As Figures 4 to 11 shown, the first 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 movable valve body 7.

[0052] As Figure 8 and Figure 9 shown, when the movable valve body 7 is in the first position state, 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. In this way, the second opening 612 and the third opening 613 connecting to the outside space are connected, and the first fluid control assembly 4 conveys air to the first infusion line 101. As Figure 11 shown, when the movable valve body 7 is in the second position state, the other end of the first sub-passage and the other end of the third sub-passage are connected, and the other end of the second sub-passage and the other end of the third sub-passage are blocked. In this way, the first opening 611 connecting to the cleaning liquid bag and the third opening 613 are connected, and the first fluid control assembly 4 conveys the cleaning liquid to the first infusion line 101. In this way, it is possible to control whether the first fluid control assembly 4 conveys gas or cleaning liquid to the first infusion line 101 by moving the movable valve body 7, so that the cleaning liquid can be smoothly introduced into the docking groove, and when conveying gas, the cleaning liquid remaining in the liquid path can be pushed to the waste water pump.

[0053] Optionally, referring to Figure 8 and Figure 9 , the cavity 6 further includes a bracket 62, and the bracket 62 covers the opening side of the receiving groove 614 of the liquid passage main body 61 to form a cavity 615. The movable valve body 7 is located within the cavity 615. By forming the cavity 615, the movable valve body 7 can move within the receiving groove 614, so as to selectively connect the first opening 611 and the third opening 613, or the second opening 612 and the third opening 613.

[0054] To enable the movable valve body 7 to abut against the actuating assembly 21 and move under an external force, the bracket 62 has a fourth opening 624, and the fourth opening 624 communicates with the accommodating groove 614. In this way, one end of the movable valve body 7 located outside the fourth opening 624 can receive the external force from the actuating assembly 21, causing the movable valve body 7 to move within the accommodating groove 614.

[0055] Optionally, referring to Figure 8 and Figure 11 , the movable valve body 7 moves in the accommodating groove 614 towards or away from the bracket 62, and one of the first opening 611 and the second opening 612 and the third opening 613 are all provided on the side of the liquid channel body 61 close to the bracket 62. Figure 9 As shown, the first opening 611 and the third opening 613 are provided on the side of the liquid channel body 61 close to the bracket 62. In some embodiments, the positions of the first opening 611 and the second opening 612 can be interchanged, that is, the originally gas-passing opening can be changed to a liquid-passing opening. At this time, the second opening 612 and the third opening 613 are provided on the side of the liquid channel body 61 close to the bracket 62.

[0056] Optionally, referring to Figure 8 and Figure 6 , since the fourth opening 624 of the bracket 62 communicates with the accommodating groove 614, to prevent the cleaning liquid from flowing out of the outlet other than the first fluid outlet 411 to other components of the device, such as flowing out from the first fluid control assembly 4 and dripping on the housing of the device, the cavity 6 can include a separator 64. The separator 64 is arranged outside the fourth opening 624 of the bracket 62 facing away from the liquid channel body 61, and wraps the area of the cavity 6 with the fourth opening 624 on the outside. In this way, the cleaning liquid input from the first fluid inlet 412 is isolated by the separator 64 within the first fluid control assembly 4 and flows out from the first fluid outlet 411.

[0057] Optionally, in the first fluid control assembly 4, a first fluid passage 41 is formed among the liquid channel body 61, the bracket 62 and the separator 64. Specifically, as Figure 4 and Figure 6 shown, the area of the bracket 62 wrapped by the separator 64 has a through hole 623 and a first communication groove 621. Both ends of the first communication groove 621 communicate with one end of the through hole 623 and the fourth opening 624 respectively, and the other end of the through hole 623 communicates with the first opening 611. As Figure 12 and Figure 13, on one side where the bracket 62 presses against the liquid passage body 61, there is a second communication groove 622. The two ends of the second communication groove 622 are respectively communicated with the accommodation groove 614 and the third opening 613. In this way, the cleaning liquid introduced from the first fluid inlet 412 passes through the first opening 611 of the liquid passage body 61, then flows through the through hole 623 and the first communication groove 621, and finally flows from the fourth opening 624 to the accommodation groove 614. The accommodation groove 614 is communicated with the second communication groove 622 that communicates with the third opening 613. Therefore, the cleaning liquid finally flows through the accommodation groove 614, through the second communication groove 622, and flows out from the first fluid outlet 411 through the third opening 613.

[0058] Specifically, when the movable valve body 7 moves towards the bracket 62 to the first position state, the movable valve body 7 leaves the second opening 612 and blocks the fourth opening 624 to block the first sub-passage formed by the first opening 611, the through hole 623, the first communication groove 621, and the third opening 613. And the movable valve body 7 leaves the second opening 612 to open the second sub-passage formed by the second opening 612 and the accommodation groove 614.

[0059] When the movable valve body 7 moves away from the bracket 62 to the second position state, the movable valve body 7 leaves the fourth opening 624 and blocks the second opening 612 to open the first sub-passage formed by the first opening 611, the through hole 623, the first communication groove 621, and the third opening 613, and blocks the second sub-passage formed by the second opening 612 and the accommodation groove 614.

[0060] When the movable valve body 7 is in the first position, the movable valve body 7 blocks the fourth opening 624. Therefore, the cleaning liquid cannot flow to the accommodation groove 614 communicated with the fourth opening 624. Therefore, when extracting air, there will be no situation of extracting the cleaning liquid from the cleaning liquid package 12. In this way, the usability of the first fluid control component 4 can be improved. And when the movable valve body 7 is in the second position, the movable valve body 7 blocks the second opening 612. Therefore, even if the fourth opening 624 is communicated with the second communication groove 622 and the second communication groove 622 is communicated with the accommodation groove 614, the cleaning liquid may flow to the vicinity of the second opening 612. But at this time, the second opening 612 is blocked by the movable valve body 7. Therefore, even if the cleaning liquid flows to the vicinity of the second opening 612, there will be no liquid leakage, improving the tightness of the first fluid control component 4. In this way, the first fluid control component 4 realizes multiple functions through a simple structure and has high usability.

[0061] Optionally, when the movable valve body 7 is in the first position, the second opening 612 and the third opening 613 are communicated through the accommodation groove 614 and the second communication groove 622. To enable gas or cleaning liquid to flow from the second opening 612 to the third opening 613, the diameter of the movable valve body 7 can be smaller than the diameter of the accommodation groove 614, or the side surface of the movable valve body 7 has an axial third communication groove to communicate the second opening 612 and the second communication groove 622 in the first position state.

[0062] Optionally, referring to Figure 14 , the movable valve body 7 may be a movable rod, and the movable rod has a convex ring 73. To enable gas or cleaning liquid to flow from the second opening 612 to the third opening 613, the radial dimension of the convex ring 73 may be smaller than the diameter of the accommodating groove 614 and larger than the dimension of the fourth opening 624. In this way, the purpose of blocking the fourth opening 624 can be achieved by using the convex ring 73. That is to say, when the movable rod is in the first position, the convex ring 73 with a radial dimension larger than the dimension of the fourth opening 624 can block the fourth opening 624.

[0063] Optionally, regarding how to determine that the convex ring 73 of the movable valve body 7 can block the fourth opening 624 and how to reset the movable valve body 7 from the second position to the first position after being subjected to an external force, the following embodiments can be adopted. As Figure 8 shown, the first fluid control assembly 4 may include an elastic member 8. The elastic member 8 is located in the cavity 615 and applies an elastic force to the convex ring 73 of the movable valve body 7 such that one end of the movable rod passes through the fourth opening 624, and at the same time, the end of the movable valve body 7 inserted into the fourth opening 624 is such that the convex ring 73 is clamped on the periphery of the fourth opening 624 to block the fourth opening 624 when not subjected to an external force; the elastic member 8 contracts when the movable valve body 7 is subjected to an external force, and at the same time, the side of the convex ring 73 close to the elastic member 8 opens the fourth opening 624 and blocks the second opening 612. Optionally, the elastic member 8 may be a spring.

[0064] For example, the elastic member 8 may be arranged at one end of the movable valve body 7 away from the fourth opening 624 and can apply an elastic force to the convex ring 73 of the movable valve body 7 such that one end of the movable rod passes through the fourth opening 624, and at the same time, the end of the movable valve body 7 inserted into the fourth opening 624 is such that the convex ring 73 is clamped on the periphery of the fourth opening 624 to block the fourth opening 624 when not subjected to an external force. When the movable valve body 7 is subjected to an external force, the elastic body in contact with the convex ring 73 is subjected to an external force and contracts, and the movable valve body 7 also moves under the action of the external force to open the fourth opening 624, and at the same time, the side of the convex ring 73 close to the elastic member 8 blocks the second opening 612. In this way, it can be achieved that the fourth opening 624 is selectively opened or blocked by the movable valve body 7, so that the cleaning liquid packet 12 or air can be selectively introduced into the first infusion path 101 through the first fluid control assembly 4.

[0065] Optionally, to strengthen the blocking of the second opening 612 by the movable valve body 7 in the first position, a sealing member may be provided on the movable valve body 7. Referring to Figure 15 and Figure 16, the movable valve body 7 may include a first seal 71 disposed at one end of the movable valve body 7 close to the second opening 612. The radial dimension of the surface of the first seal 71 facing the second opening 612 is greater than the inner diameter of the second opening 612 to block the second opening 612 when the movable valve body 7 is subjected to an external force.

[0066] Optionally, the first seal 71 may be a flexible component sleeved on the outer periphery of the convex ring 73. When the movable valve body 7 moves to block the second opening 612, the flexible seal deforms, thereby tightly blocking the second opening 612.

[0067] Optionally, the radial dimension of the first seal 71 is smaller than the diameter of the receiving groove 614, so that when the movable valve body 7 is in the first position, a gap is formed between the first seal 71 and the inner wall of the receiving groove 614 to communicate the second opening 612 and the second communication groove 622.

[0068] Optionally, refer to Figure 8 , the circumferential side of the movable rod sleeving the first seal 71 has a second limiting ring 712, and the second seal 72 wraps the second limiting ring 712.

[0069] Optionally, the side surface of the first seal 71 may have an axial fifth communication groove, so that the air flowing in from the second opening 612 can be connected to the second communication groove 622 through the fifth communication groove, and thus can flow out of the first fluid control assembly 4 from the first fluid outlet 411.

[0070] Optionally, one end of the movable rod having the first seal 71 extends beyond the first seal 71 and is inserted into the second opening 612. In some embodiments, when the movable valve body 7 is in the second position, one end of the movable rod having the first seal 71 extends beyond the first seal 71 and is inserted into the second opening 612. Thus, while the first seal 71 blocks the second opening 612, it can also be realized that the end of the movable rod having the first seal 71 blocks the air inlet 92, thereby strengthening the effect of blocking the second opening 612.

[0071] Optionally, the radial dimension of one end of the movable rod close to the second opening 612 is smaller than the radial dimension of the second opening 612 to pass fluid while limiting the movable rod. For example, the second opening 612 may be a circular hole, and the cross-section of the movable rod in the radial direction may be a square surface, and the length of the connection line between the diagonals of the square surface is the same as the diameter of the circular hole of the opening. Thus, fluid can pass while limiting the movable rod.

[0072] Optionally, to strengthen the effect of the movable valve body 7 blocking the fourth opening 624, the convex ring 73 includes at least a second seal 72 located on the surface of the convex ring 73.

[0073] When the second seal 72 seals the fourth 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 seal 72 is smaller than the diameter of the receiving groove 614 or the side surface of the second seal 72 has an axial fourth communication groove. A gap is formed between the second seal 72 and the inner wall of the receiving groove 614 to communicate the second opening 612 and the second communication groove 622.

[0074] Optionally, the second seal 72 is sleeved on the moving rod. The circumferential side of the moving rod sleeved with the second seal 72 has a first limiting ring 721, and the second seal 72 wraps the first limiting ring 721. By providing the first limiting ring 721 on the circumferential side of the moving rod sleeved with the second seal 72 and the second seal 72 wrapping the first limiting ring 721, the position of the second seal 72 on the moving rod can be fixed, avoiding the situation that the second seal 72 cannot completely seal the fourth opening 624 when the movable valve body 7 is in the first position state, thereby improving the usability and working effect of the first fluid control assembly 4.

[0075] Optionally, refer to Figure 8 , the area of the spacer 64 corresponding to the fourth opening 624 is a transmission part 641. The transmission part 641 is used to receive the force outside the spacer 64 and deform under the force to abut against the movable valve body 7.

[0076] Optionally, the transmission part 641 is an elastic member. The side of the transmission part 641 facing away from the fourth opening 624 deforms towards the fourth opening 624 under the force, abuts against and pushes the movable valve body 7 to move, so that the movable valve body 7 blocking the fourth opening 624 leaves the fourth opening 624. After the external force is released, the transmission part 641 elastically restores and is spaced from the fourth opening 624. For example, the spacer 64 can be silica gel.

[0077] Optionally, refer to Figure 15 , the side of the bracket 62 close to the spacer 64 has a groove 625. The spacer 64 covers the bottom of the groove 625. The first fluid control assembly 4 further includes a gland 9. The shape of the gland 9 is adapted to the groove 625. The gland 9 is pressed on the groove 625 and presses the edge of the spacer 64 against the bottom of the groove 625. The side of the gland 9 facing the fourth opening 624 has a first through groove 91. The first through groove 91 avoids the part of the spacer 64 corresponding to the fourth opening 624. The external force operates on the movable valve body 7 through the first through groove 91. By pressing the gland 9 on the groove 625 and pressing the edge of the spacer 64 against the bottom of the groove 625, the structural tightness of the first fluid control assembly 4 can be improved.

[0078] For example, the actuating assembly 21 abuts against the transmission part 641 through the first through groove 91. The actuating assembly 21 applies a force to the transmission part 641, causing the transmission part 641 to deform. The movable valve body 7 moves, and the movable valve body 7 blocking the fourth opening 624 leaves the fourth opening 624.

[0079] Optionally, in order not to require an additional air inlet channel outside the first fluid control assembly 4, an air inlet channel 616 can be provided in the liquid channel main body 61 of the first fluid control assembly 4. Specifically, as Figure 15 and Figure 16 shown, the gland 9 has an independent air inlet 92, the liquid channel main body 61 has an air inlet channel 616, one end 6161 of the air inlet channel is connected to the air inlet 92, the other end 6162 of the air inlet channel communicates with the second opening 612, and the air inlet channel 616 sequentially penetrates through the gland 9, the spacer 64, the bracket 62 and the liquid channel main body 61. Specifically, the bracket 62 has a first through hole 626, the spacer 64 has a second through hole 642, and one end 6161 of the air inlet channel is sequentially connected to the first through hole 626, the second through hole 642 and the air inlet 92. The air inlet 92 can be provided on the outer periphery of the reagent kit 1, that is, an independent air inlet 92 is provided on the gland 9 for introducing air into the first fluid control assembly 4. Therefore, the air inlet channel 616 can sequentially penetrate through the gland 9, the spacer 64, the bracket 62 and the liquid channel main body 61, and finally communicate with the second opening 612 through the liquid channel main body 61.

[0080] Optionally, as Figure 16 and Figure 8 shown, the liquid channel main body 61 can include a receiving groove main body 617 and a cover body 618. The receiving groove main body 617 has parallel first through grooves 6171 and second through grooves 6172. The cover body 618 is covered on the same-side end of the first through groove 6171 and the second through groove 6172. There is a fifth communication groove 6175 between the cover body 618 and the receiving groove main 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 a receiving groove 614, and the fifth communication groove 6175 and the second through groove 6172 form the air inlet channel 616.

[0081] By providing the air inlet channel 616 in the first fluid control assembly 4, the air channel and the liquid channel can be integrated inside the first fluid control assembly 4, without the need to provide an additional air inlet channel to connect the first fluid control assembly 4 to the external space.

[0082] Optionally, as Figure 15 and Figure 16As shown in the figure, the cavity 6 may include a third seal 63 for guiding the liquid flowing in the first fluid control component 4 and improving the sealing performance of the first fluid control component 4 to reduce liquid leakage. Specifically, the third seal 63 may have two convex portions 631. An extension portion 619 extends laterally from the opening edge of the accommodation groove 614 of the liquid channel body 61. The extension portion 619 has a clamping groove 6191 on the side facing the bracket 62. The accommodation groove 614 is formed at the bottom of the clamping groove 6191. The third seal 63 is clamped in the clamping groove 6191. The third seal 63 is provided with a fifth opening 635. The fifth opening 635 communicates with the accommodation groove 614 and the fourth opening 624. The extension portion 619 corresponding to the convex portion 631 has a through hole 6192. The convex portion 631 is inserted into the through hole 6192. The convex portion 631 has a through hole 6311. One end of the through hole 6311 of one convex portion 631 facing away from the third seal 63 serves as the first opening 611, and the other end communicates with the first opening 611 and the through hole 623. One end of the through hole 6311 of the other convex portion 631 facing away from the third seal 63 serves as the third opening 613, and the other end communicates with the second communication groove 622.
