[0022] To make the above objects, features and advantages of the present application more obvious and understandable, the following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application rather than all the structures are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0023] The terms "first", "second", etc. in the present 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 optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0024] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears at various positions in the specification and 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.

[0025] With the gradual progress of analysis techniques, the sampling component of a blood gas analyzer can be used to obtain samples and / or other reagents, and then the sampling component is docked with the docking slot of the blood gas analyzer, so that the samples and / or other reagents in the sampling component can be input into the detection component of the blood gas analyzer through the pipeline in the docking slot. In the testing process of the blood gas analyzer in the related art, the liquid in the liquid bag is connected to the blood gas analyzer through the valve component of the blood gas analyzer, so that the liquid in the liquid bag enters the blood gas analyzer for measurement and analysis, and the waste liquid generated inside the blood gas analyzer flows into the liquid bag.

[0026] When the valve assembly is docked with the liquid bag, the liquid inlet of the valve assembly is docked with the liquid outlet of the liquid bag to achieve the connection of the channel. In the related art, it often occurs that it is difficult to dock the liquid inlet and the liquid outlet, and problems such as poor docking and liquid leakage are also likely to occur. And in the related art, the valve assembly is likely to cause bubbles to be generated in the liquid flowing through the valve assembly during the working process, thereby affecting the analysis accuracy of the blood gas analyzer.

[0027] In order to improve or solve the above technical problems, the present application proposes at least the following embodiments.

[0028] As Figure 1-2 shown, the present application proposes a blood gas analyzer 1. The blood gas analyzer 1 may include a device body 10 and a reagent kit 20. Among them, the reagent kit 20 is replaceably docked with the device body 10.

[0029] In some embodiments, the device body 10 may include: a sampling component (not labeled in the figure), a sample analysis component (not labeled in the figure), a control module (not labeled in the figure), a data processing module (not labeled in the figure), a display component (not labeled in the figure), and other devices. Among them, the sample analysis component is used to detect the sample by using a test card and a reagent introduced into the test card. The sampling component is used to extract and transport the liquid in the reagent kit or from the outside to the test card. It can be understood that the sampling component may be provided in the reagent kit 20. That is to say, the sampling component may not be provided on the device body 10. The control module is used to control the related processes of liquid extraction and detection. The data processing module is used to process and analyze the data generated by the detection to obtain the corresponding detection results. The display component is used to display information such as the detection results.

[0030] Optionally, as Figure 3-4 shown, in some embodiments, the present application provides a reagent kit 20 for the blood gas analyzer 1. The reagent kit 20 includes: a box body 21, a channel component 250, and a liquid passing valve 22. Among them, the box body 21 is provided with a receiving cavity, and the receiving cavity is provided with a liquid bag 24. Among them, the liquid bag 24 may include any one of a standard liquid bag, a cleaning liquid bag, and a waste liquid bag. The liquid passing valve 22 is provided on the box body 21 and is located between the liquid bag 24 and the channel component 250. The liquid passing valve 22 is used to dock with the liquid bag 24 and the channel component 250 respectively. The channel component 250 is docked with the sample analysis component. The liquid passing valve 22 is used to selectively connect or disconnect the channel component 250 and the liquid bag 24.

[0031] Specifically, the liquid bag 24, the channel assembly 250, and the liquid passage valve 22 are all arranged on the cartridge body 21. Such an arrangement can effectively reduce the space occupancy rate of components for guiding the flow, such as the channel assembly 250 and the liquid passage valve 22, on the equipment body 10. Moreover, components for guiding the flow in the reagent kit 20, such as the liquid bag 24, the channel assembly 250, and the liquid passage valve 22, are more likely to malfunction or be damaged. Therefore, by integrating components such as the liquid bag 24, the channel assembly 250, and the liquid passage valve 22 on the cartridge body 21, when it is necessary to repair or replace components such as the liquid bag 24, the channel assembly 250, and the liquid passage valve 22, only the separate reagent kit 20 needs to be taken out, and then the components such as the liquid bag 24, the channel assembly 250, and the liquid passage valve 22 on it can be repaired or replaced, without disassembling the equipment body 10, thereby effectively reducing the maintenance cost of the blood gas analyzer 1.

[0032] Moreover, the channel assembly 250 and the liquid passage valve 22 are arranged on the cartridge body 21, that is, the equipment body 10 does not have fluid passages, such as the liquid channel 220g (as Figure 7 shown), the gas channel, and the diversion channel (the diversion channel can be understood as the fluid channel arranged in the channel assembly 250), etc., so that the reagent kit 20 is in fluid communication with the test card, and there is no fluid path docking between the reagent kit 20 and the equipment body 10 outside the test card. Thus, while effectively improving the docking convenience between the reagent kit 20 and the equipment body 10, it can also effectively avoid liquid leakage when the reagent kit 20 is docked with the equipment body 10.

[0033] Optionally, as Figure 5-7 shown, in some embodiments, the liquid passage valve 22 includes a valve body assembly 220 and a switch assembly 221.

[0034] Among them, the valve body assembly 220 is provided with a first channel port 220a and a second channel port 220b. The first channel port 220a is used to connect with the liquid bag 24, the second channel port 220b is used to output liquid, and a liquid channel 220g is formed between the first channel port 220a and the second channel port 220b.

[0035] Further, the switch assembly 221 includes a movable member 2210 (in some embodiments, the movable member 2210 is also referred to as the second part of the switch assembly 221). The movable member 2210 can deform at least a part of the liquid channel 220g, thereby closing or connecting the liquid channel 220g, so that the channel assembly 250 is selectively disconnected or connected to the liquid bag 24. For example, when the blood gas analyzer 1 needs to analyze a sample, the liquid channel 220g can be controlled to be connected through the movable member 2210, so that the liquid in the liquid bag 24 (such as a calibration liquid bag containing calibration liquid) can flow to the sample analysis assembly, thereby realizing the analysis of the sample. When sample analysis is not required, the liquid channel 220g can be controlled to be closed through the movable member 2210. For another example, when the fluid channel needs to be cleaned, the liquid channel 220g can be controlled to be connected through the movable member 2210, so that the liquid channel 220g can be connected to the fluid channel between the second channel port 220b and the sample analysis assembly, so that the cleaning liquid in the liquid bag 24 (such as a cleaning liquid bag containing cleaning liquid) can flow in the fluid channel to clean the fluid channel. It should be noted that the deformation of the liquid channel 220g can be understood as a change in the overall or local spatial form of the liquid channel 220g.

[0036] Moreover, the movable member 2210 is located outside the liquid channel 220g, that is, the movable member 2210 is arranged outside the liquid channel 220g to isolate the liquid from the movable member 2210. Specifically, since the movable member 2210 needs to move or travel quickly when controlling the deformation of the liquid channel 220g, arranging the movable member 2210 outside the liquid channel 220g can effectively reduce the probability of air bubbles appearing in the liquid in the liquid channel 220g, thereby effectively improving the analysis accuracy of the blood gas analyzer 1. In addition, arranging the movable member 2210 outside the liquid channel 220g can also effectively prevent the movable member 2210 from contaminating the liquid flowing through the liquid channel 220g, thereby effectively ensuring the quality of the calibration liquid or other liquids in the liquid bag 24, and further effectively improving the analysis accuracy of the blood gas analyzer 1.

[0037] Optionally, as Figure 6 shown, in some embodiments, the valve body assembly 220 includes: a valve body 2201 and a sealing portion (not labeled in the figure). Among them, the valve body 2201 forms a part of the liquid channel 220g, and the second channel port 220b is arranged on the valve body 2201; the sealing portion is arranged on the valve body 2201, and a part of the liquid channel 220g is formed between the sealing portion and the valve body 2201.

[0038] For example, in some embodiments, the sealing portion may be a flexible pipe fitting such as a hose. The sealing portion is used to separately form the deformable portion of the liquid passage 220g. The movable member 2210 is used to deform the sealing portion so as to deform the liquid passage 220g, thereby enabling the liquid passage valve 22 to selectively connect or disconnect the channel assembly 250 and the liquid bag 24.

[0039] Alternatively, in some implementations, the sealing portion and the valve body 2201 may cooperate together to form the deformable portion of the liquid passage 220g, so that the movable member 2210 can move the sealing portion relative to the valve body 2201 by holding, and change the spatial shape of the portion of the liquid passage 220g formed by the cooperation of the sealing portion and the valve body 2201, that is, to deform the liquid passage 220g, and further enable the liquid passage valve 22 to selectively connect or disconnect the channel assembly 250 and the liquid bag 24.

[0040] Optionally, as Figure 5-7 shown, in some embodiments, the liquid passage 220g at least includes a first liquid sub-passage 220c and a second liquid sub-passage 220d. Among them, the second liquid sub-passage 220d is the deformable portion of the liquid passage 220g. Specifically, the first end of the first liquid sub-passage 220c is docked with the second channel port 220b, the second end of the second liquid sub-passage 220d is docked with the first end of the first liquid sub-passage 220c, the second end of the second liquid sub-passage 220d is docked with the first channel port 220a. The first liquid sub-passage 220c is disposed in the valve body 2201. The sealing portion includes a sealing assembly 2200. The sealing assembly 2200 is movably matched with the valve body 2201 to jointly enclose and form the second liquid sub-passage 220d with the valve body 2201. The sealing assembly 2200 is used to move or deform relative to the valve body 2201 under the drive of the movable member 2210, so as to close or connect the second liquid sub-passage 220d, and further enable the liquid passage valve 22 to selectively connect or disconnect the channel assembly 250 and the liquid bag 24.

[0041] Specifically, as Figure 7-9As shown, the valve body 2201 is provided with a first recessed portion 2201a spaced apart from the second channel opening 220b, the second end of the first liquid sub-channel 220c is provided in the first recessed portion 2201a, and the sealing assembly 2200 includes: a blocking member 2203. The blocking member 2203 includes a central body portion 2203a and a connecting portion 2203b arranged around the outer edge of the central body portion 2203a. The central body portion 2203a is linked with the movable member 2210 and movably cooperates with the first recessed portion 2201a to enclose and form a second liquid sub-channel 220d, wherein at least part of the central body portion 2203a is arranged to be movable relative to the valve body 2201, so that all or part of the central body portion 2203a blocks or opens the second end of the first liquid sub-channel 220c, thereby closing or connecting the liquid channel 220g. Furthermore, the connecting portion 2203b is sealedly fitted with the peripheral area of ​​the first recessed portion 2201a, so that the connecting portion 2203b and the peripheral area of ​​the first recessed portion 2201a are sealed, thereby effectively ensuring the sealing of the connection between the sealing member 2203 and the valve body 2201, and effectively preventing liquid from leaking along the connection between the valve body 2201 and the sealing member 2203, thereby effectively improving the sealing of the liquid channel 220g and reducing the probability of leakage inside the liquid valve 22.

[0042] Specifically, the movable member 2210 and the central body 2203a are in linkage, which means that the force-bearing member 2210 will trigger the movable member 2210 to move when it moves, so that the position of the movable member 2210 changes. The linkage between the two components is explained as follows.

[0043] Furthermore, if Figure 7-9 As shown, in some embodiments, the connection part 2203b or the valve body 2201 is provided with an annular sealing structure 2203g, which is arranged around the outer periphery of the first recessed part 2201a and located between the connection part 2203b and the valve body 2201. The annular sealing structure 2203g is used for filling and dispensing or for deforming under the mutual extrusion of the connection part 2203b and the valve body 2201 to seal the outer periphery of the first recessed part 2201a, thereby effectively improving the sealing performance of the connection between the plugging member 2203 and the valve body 2201. For example, the plugging member 2203 is a flexible component. When the plugging member 2203 is formed, the annular sealing structure 2203g can be used as a part of the plugging member 2203 and integrally formed on the connection part 2203b of the plugging member 2203, so that the components of the liquid-passing valve 22 can be effectively simplified, thereby effectively improving the assembly efficiency of the liquid-passing valve 22.

[0044] Alternatively, in some embodiments, the valve body assembly 220 includes an annular seal (not shown in the figures). The annular seal surrounds the outer periphery of the first recess 2201a and is located between the connecting portion 2203b and the valve body 2201 to seal the connection between the plugging member 2203 and the valve body 2201, thereby effectively improving the sealing performance of the connection between the plugging member 2203 and the valve body 2201. For example, the annular seal can be an element with sealing performance such as a rubber ring.

[0045] Further, as Figure 7-9 shown, in some embodiments, a first groove 2201b is formed by the bottom depression of the first recess 2201a. The second end of the first liquid sub-channel 220c is disposed within the first groove 2201b. The plugging member 2203 includes a convex top structure 2203c that protrudes relative to the central main body portion 2203a (that is, the convex top structure 2203c is formed by a part of the central main body portion 2203a protruding). The convex top structure 2203c is movably engaged with the first groove 2201b, and the convex top structure 2203c is connected to the movable member 2210 and is used to move relative to the valve body 2201 under the drive of the movable member 2210 to plug or open the second end of the first liquid sub-channel 220c. Specifically, the first groove 2201b is the inner groove structure of the first recess 2201a, that is, the first recess 2201a is arranged as a structure of a groove within a groove. The radial structural dimension of the first groove 2201b is smaller than the radial structural dimension of the first recess 2201a. The first groove 2201b with a smaller structural dimension is movably engaged with the convex top structure 2203c with a smaller structural dimension, and the movable member 2210 is connected to the convex top structure 2203c, so that the acting force of the movable member 2210 on the plugging member 2203 can be more effectively concentrated in the vicinity of the area near the second end of the first liquid sub-channel 220c, thereby enabling the plugging member 2203 to better plug the second end of the first liquid sub-channel 220c, and further effectively improving the sealing performance of the liquid passage valve 22 in the closed state, and effectively reducing the probability of gas entering the liquid bag 24 when the liquid passage valve 22 is in the closed state (that is, when the liquid passage 220g is closed).

[0046] Further, when the movable member 2210 controls the plugging member 2203 to open the second end of the first liquid sub-channel 220c, the entire central main body portion 2203a will move relative to the valve body 2201 to effectively expand the volume of the second liquid sub-channel 220d, and further effectively reduce the risk of generating noise due to the flow of liquid in the second liquid sub-channel 220d with too small a volume when the second end of the first liquid sub-channel 220c is opened.

[0047] Optionally, as Figure 7-9As shown, in some embodiments, the blocking member 2203 also serves as a component docking with the first channel opening 220a, so that the second sub-channel docks with the first channel opening 220a. Such a configuration can effectively improve the parts reuse rate of the liquid-passing valve 22, thereby effectively simplifying the component composition of the liquid-passing valve 22, and further effectively improving the assembly efficiency of the liquid-passing valve 22. Specifically, the blocking member 2203 also includes a guide portion 2203d, the guide portion 2203d is arranged between the connecting portion 2203b and the central main body portion 2203a, the guide portion 2203d forms a third liquid sub-channel 220e, the guide portion 2203d is arranged on a side facing the valve body 2201 with a first end of the third liquid sub-channel 220e, for docking with the second liquid sub-channel 220d, and the guide portion 2203d is arranged on a side away from the valve body 2201 with a second end of the third liquid sub-channel 220e, for docking with the first channel opening 220a.

[0048] Alternatively, if Figure 7 As shown, in some embodiments, the valve body 2201 is further provided with a second groove 220f, and the second groove 220f is connected to the second liquid sub-channel 220d. The second groove 220f is arranged opposite to the guide portion 2203d, and is connected to the second end of the third liquid sub-channel 220e. In this way, the first groove 2201b can serve as a buffer groove between the first end of the third liquid sub-channel 220e and the second end of the second liquid sub-channel 220d, thereby effectively reducing the working noise of the liquid valve 22 when it is in an open state.

[0049] Alternatively, if Figure 7 As shown, in some embodiments, the sealing assembly 2200 further includes a pressing member 2202, which is disposed on the side of the blocking member 2203 away from the valve body 2201, and is used to press the connection portion 2203b against the valve body 2201. Specifically, the hardness of the pressing member 2202 and the hardness of the valve body 2201 are both higher than the hardness of the blocking member 2203, so the pressing member 2202 is further disposed on the side of the blocking member 2203 away from the valve body 2201, so that the connection portion 2203b of the blocking member 2203 is pressed against one side of the valve body 2201 through the pressing member 2202, thereby effectively improving the sealing between the connection portion 2203b and the valve body 2201.

[0050] Furthermore, if Figure 7 and Figure 9As shown, in some embodiments, the valve body 2201 is provided with an abutment plane 2201c which is arranged around the periphery of the first recessed portion 2201a and protrudes relative to the first recessed portion 2201a, the connecting portion 2203b is arranged opposite to the abutment plane 2201c, and the pressing member 2202 is used to press the connecting portion 2203b against the abutment plane 2201c, so that the connecting portion 2203b can be attached to the abutment plane 2201c under the interaction between the pressing member 2202 and the valve body 2201, thereby effectively improving the sealing between the connecting portion 2203b and the valve body 2201.

[0051] Alternatively, if Figure 7 , Figure 9 and Figure 10 As shown, in some embodiments, the liquid-passing valve 22 further includes a docking body 222, which is disposed on the box body 21, and the docking body 222 forms a receiving space 222b with an opening, wherein the valve body 2201, the sealing assembly 2200 and the movable part 2210 are all disposed in the receiving space 222b. Specifically, the docking body 222 serves as a docking piece between the liquid-passing valve 22 and the box body 21, and it also forms a receiving space 222b, and the valve body assembly 220 and the switch assembly 221, such as the valve body 2201, the sealing assembly 2200 and the movable part 2210, are all disposed in the receiving space 222b. Such a configuration can effectively reduce the risk of the liquid-passing valve 22 being accidentally opened or closed.

[0052] Furthermore, in some embodiments, the valve body 2201 is embedded in the accommodating space 222b, and the sealing component 2200 and the movable part 2210 are both located on the side of the valve body 2201 away from the opening of the accommodating space 222b. In other words, the sealing component 2200 and the movable part 2210 are both located on the side of the valve body 2201 away from the opening end of the docking body 222. This arrangement enables the sealing component 2200 and the movable part 2210 to be located in the area between the bottom wall 222a of the docking body 222 and the valve body 2201, thereby effectively preventing either the sealing component 2200 or the movable part 2210 from being accidentally touched, causing the liquid channel 220g to be accidentally connected or closed, thereby effectively improving the working stability of the liquid valve 22.

[0053] Alternatively, if Figure 6-7As shown, the switch assembly 221 also includes a force-bearing member 2211 (in some embodiments, the force-bearing member 2211 is also referred to as the first part of the switch assembly 221). The force-bearing member 2211 is linked with the movable member 2210, and the force-bearing member 2211 is used to receive external force, so as to drive the movable member 2210 to move under the action of the external force, so as to connect or close the liquid channel 220g. Specifically, a part of the force-bearing member 2211 is located on the side of the opening of the valve body 2201 toward the accommodating space 222b, and is used to receive external force, and another part of the force-bearing member 2211 is linked with the movable member 2210, so as to drive the movable member 2210 to move. With such arrangement, the reagent kit 20 can be mechanically docked with the actuator of the blood gas analyzer 1 through the force-bearing member 2211, so that the flow of the fluid on the reagent kit 20 can be controlled without liquid docking between the device body 10 and the reagent kit 20, thereby effectively improving the docking convenience between the reagent kit 20 and the device body 10 and effectively avoiding liquid leakage when the reagent kit 20 and the device body 10 are docked.

[0054] For example, in some embodiments, another part of the force-bearing member 2211 can be linked with the movable member 2210 by means of magnetic coupling, or another part of the force-bearing member 2211 (for example, the extended bracket bar 2211a of the force-bearing member 2211) can extend to the side of the valve body 2201 away from the opening of the accommodating space 222b, and abut against the movable member 2210, thereby achieving linkage cooperation.

[0055] Furthermore, the force-bearing member 2211 is located outside the liquid channel 220g so that the liquid is isolated from the force-bearing member 2211. Specifically, since the force-bearing member 2211 needs to move or move quickly when it is linked with the movable member 2210, the force-bearing member 2211 is arranged outside the liquid channel 220g, which can effectively reduce the probability of bubbles appearing in the liquid in the liquid channel 220g, thereby effectively improving the analysis accuracy of the blood gas analyzer 1. In addition, the force-bearing member 2211 is arranged outside the liquid channel 220g, which can also effectively prevent the force-bearing member 2211 from contaminating the liquid flowing through the liquid channel 220g, thereby effectively ensuring the quality of the calibration liquid or other liquid in the liquid bag 24, thereby effectively improving the analysis accuracy of the blood gas analyzer 1.

[0056] Alternatively, if Figure 6As shown, in some embodiments, the force-bearing member 2211 includes a plate 2211b and one or two extended bracket strips 2211a, the plate 2211b is mounted between the two extended bracket strips 2211a, the plate 2211b is arranged on the side of the opening of the valve body 2201 facing the accommodating space 222b, the extended bracket strip 2211a extends to the space on the side of the opening of the valve body 2201 away from the accommodating space 222b, the extended bracket strip 2211a is used to abut against the movable member 2210, and the plate 2211b is used to receive external force so that the extended bracket strip 2211a drives the movable member 2210 to move. Specifically, the extended support strip 2211a is the part of the force-bearing member 2211 that cooperates with the movable member 2210, and the plate member 2211b is the part of the force-bearing member 2211 that receives external force. The part of the force-bearing member 2211 that receives external force is set as a plate-shaped plate member 2211b, and the part of the force-bearing member 2211 that cooperates with the movable member 2210 is set as a strip-shaped extended support strip 2211a, which can effectively reduce the structural size of the force-bearing member 2211, thereby effectively reducing the weight of the liquid valve 22. Under the premise of meeting the force strength, the radial size of the plate member 2211b (that is, the plate surface size of the plate member 2211b) can be set as small as possible to reduce the probability of the plate member 2211b being accidentally touched.

[0057] Of course, in some embodiments, the number of the extended support bars 2211 a may also be three or four, etc., so as to effectively improve the structural strength of the force-bearing member 2211 .

[0058] Alternatively, if Figure 6-9As shown, in some embodiments, the movable member 2210 is a rod-shaped movable rod 2210a. One end of the movable rod 2210 is connected to the central main body portion 2203a, and the other end is movably engaged with the docking main body 222. The axial direction of the movable rod 2210 is the same as the acting direction of the external force (in some embodiments, the acting direction of the external force is perpendicular to the plate surface of the plate member 2211b). Specifically, in some embodiments, a clamping groove is formed on the side of the convex top structure 2203c facing away from the valve main body 2201, and a clamping buckle is formed at one end of the movable rod 2210. The clamping buckle is clamped and engaged with the clamping groove to fixedly connect the movable rod 2210 to the convex top structure 2203c, thus effectively improving the assembly efficiency between the movable rod 2210 and the plugging member 2203. Further, the switch assembly 221 further includes a switch pressing piece 2213, and the switch pressing piece 2213 is in linkage cooperation with the movable rod 2210 (for example, the switch pressing piece 2213 can be in linkage cooperation with the movable rod 2210 by being fixedly connected, that is, fixing the switch pressing piece 2213 on the movable rod 2210). The two extending support strips 2211a respectively abut against or are connected to both ends of the switch pressing piece 2213, so that the switch pressing piece 2213 can be in linkage cooperation with the force-receiving member 2211, and further the force-receiving member 2211 and the movable rod 2210 are in linkage cooperation. The sealing portion (or the sealing assembly 2200) is located in the space between the two extending supports, the plate member 2211b and the switch pressing piece 2213, so as to effectively avoid the interference of the linkage cooperation between the two extending supports, the plate member 2211b and the switch pressing piece 2213 on the sealing portion.

[0059] Optionally, as Figure 7 and Figure 10 shown, in some embodiments, a second recessed portion 2220 is provided on the bottom wall 222a of the docking main body 222. The first recessed portion 2201a is disposed opposite to the second recessed portion 2220 to enclose an activity space. The switch pressing piece 2213, the movable rod 2210 and the central main body portion 2203a are all located in the activity space. Specifically, the second recessed portion 2220 includes a first activity groove 2222 and a second activity groove 2221 that communicate with each other. The second activity groove 2221 is provided at the bottom of the first activity groove 2222. The switch pressing piece 2213 is movably disposed in the first activity groove 2222, and at least a part of the movable rod 2210 is disposed in the second activity groove 2221. At least a part of the circumferential side surface of the movable rod 2210 is in sliding cooperation with the groove wall of the second activity groove 2221. In this way, the groove wall of the second activity groove 2221 restricts the freedom degree of the activity along its radial direction, so that the axial direction of the movable rod 2210 can always be parallel to the acting direction of the external force, effectively improving the movement stability of the movable rod 2210, and further effectively improving the working stability of the liquid passing valve 22.

[0060] Optionally, asFigure 7 As shown, in some embodiments, in the absence of an external force, the movable member 2210 is arranged to close the liquid channel 220g. For example, in some embodiments, when the execution component of the blood gas analyzer 1 provides an external force to the force-receiving member 2211, or when the reagent kit 20 is not docked with the device body 10, the movable member 2210 is arranged to be able to close the liquid channel 220g, so as to effectively ensure that the liquid passage valve 22 is always in a closed state in the natural state, thereby effectively preventing the liquid bag 24 from leaking or admitting air during the transfer or assembly of the reagent kit 20.

[0061] Specifically, as Figure 6-7 As shown, in some embodiments, the movable member 2210 is provided with an abutting portion, such as a switch pressing piece 2213. The switch assembly 221 further includes an elastic member 2212, which is arranged on the opening side of the valve body 2201 facing away from the accommodating space 222b, that is, arranged in the second movable groove 2221. One end of the elastic member 2212 abuts against the abutting portion, and the other end of the elastic member 2212 abuts against the docking body 222, for providing an elastic force to the movable member 2210, so that the movable member 2210 (such as the movable rod 2210) presses against the sealing portion, thereby closing the liquid channel 220g.

[0062] Optionally, as Figure 6-9 As shown, in some embodiments, the connecting portion 2203b is located between the docking body 222 and the bottom wall 222a of the docking body 222. The docking body 222 is further used to press the connecting portion 2203b against the bottom wall 222a of the docking body 222, so as to effectively improve the sealing performance between the connecting portion 2203b and the valve body 2201. Among them, in some embodiments, the connecting portion 2203b abuts against the bottom wall 222a of the docking body 222 through a pressing member 2202.

[0063] Optionally, as Figure 9-10 As shown, in some embodiments, a connecting structure 2201d is provided on one side of the valve body 2201 facing the bottom wall 222a. The bottom wall 222a is provided with a through hole 2226. The through hole 2226 communicates the accommodating space 222b with the outside of the docking body 222, and the through hole 2226 is spaced from the first channel port 220a. The reagent kit 20 further includes a connecting component (not shown in the figure). A part of the connecting component abuts against the bottom wall 222a, and another part of the connecting component passes through the through hole 2226 and is connected to the connecting structure 2201d, so as to effectively improve the connection stability between the valve body 2201 and the docking body 222.

[0064] Optionally, as Figure 7As shown, in some embodiments, the first channel opening 220a is disposed on the bottom wall 222a of the docking body 222, and the first channel opening 220a is spaced apart from the second recess 2220, so that there is a structural basis on the docking body 222 for disposing the movable member 2210 outside the liquid channel 220g.

[0065] Further, as Figure 8-10 shown, in some embodiments, the valve body assembly 220 includes a diversion portion 2203d, that is, as described above, the plugging member 2203 is provided with a diversion portion 2203d, and the diversion portion 2203d forms a third liquid sub-channel 220e. Among them, the diversion portion 2203d is partially embedded in the first channel opening 220a so that the third liquid sub-channel 220e is docked with the first channel opening 220a.

[0066] Specifically, in some embodiments, on the side of the bottom wall 222a of the docking body 222 facing the valve body assembly 220 (that is, the side facing the valve body 2201), there are an embedding groove 2224 and a sealing plane 2225. The sealing plane 2225 is disposed around the periphery of the embedding groove 2224. The first channel opening 220a is disposed at the bottom of the embedding groove 2224 (it can also be understood that one end of the first channel opening 220a close to the accommodation space 222b expands to form the embedding groove 2224). The diversion portion 2203d includes an embedding main body 2203e and an annular sealing portion 2203f. Among them, the embedding main body 2203e is used to form the third liquid sub-channel 220e, and the annular sealing portion 2203f is disposed around the periphery of the embedding main body 2203e. Further, at least a part of the embedding main body 2203e is embedded in the embedding groove 2224, and the annular sealing portion 2203f is in sealing contact with the sealing plane 2225, so as to realize the sealing docking of the diversion portion 2203d and the first channel opening 220a, and further effectively improve the sealing performance of the liquid channel 220g.

[0067] Among them, in some embodiments, the sealing plane 2225 is recessed as a whole towards the inside of the bottom wall 222a of the docking body 222, so as to form an annular groove around the periphery of the embedding groove 2224. Among them, the annular sealing portion 2203f is embedded in the annular groove and is in sealing contact with the bottom surface of the annular groove (that is, the sealing plane 2225).

[0068] Optionally, as Figure 7-10 shown, in some embodiments, the annular sealing portion 2203f is located on the side of the pressing member 2202 away from the connecting portion 2203b. The pressing member 2202 abuts against the annular sealing portion 2203f to press the annular sealing portion 2203f into the annular groove, so as to effectively improve the docking sealing performance between the diversion portion 2203d and the first channel opening 220a.

[0069] Optionally, asFigure 5-7 As shown, in some embodiments, the kit 20 further includes an end cap 223, and the end cap 223 covers the opening of the accommodation space 222b. Among them, the plate member 2211b (in some embodiments, also referred to as a part of the force-bearing member 2211) is located between the end cap 223 and the valve body 2201. In this way, the whole or part of the force-bearing member 2211 is located in the space between the end cap 223 and the docking body 222, thereby effectively reducing the probability of accidental contact with the force-bearing member 2211, and further effectively improving the working stability of the liquid passage valve 22. Further, the end cap 223 and the force-bearing member 2211 are arranged at intervals (or at least along the direction of the external force, the plate member 2211b and the end wall of the end cap 223 are arranged at a preset interval distance). In this way, during the assembly process of the end cap 223 and the docking body 222, it can effectively prevent the end cap 223 from coming into contact with the force-bearing member 2211, thereby accidentally opening the liquid passage valve 22, resulting in gas entering the liquid package and affecting the quality of the calibration liquid in the liquid package.

[0070] Optionally, in some embodiments, the switch assembly 221 further includes a magnetic member, and the magnetic member is arranged on the plate member 2211b; or the plate member 2211b is a magnetic member, and the magnetic member is connected to a part of the force-bearing member 2211; among them, the magnetic member is used to couple with the execution assembly of the blood gas analyzer 1 to drive the movable member 2210 to move. With such a setting, the force-bearing member 2211 can achieve non-contact transmission with the execution assembly located outside the docking body 222, so that the force-bearing member 2211 does not need to be exposed outside the docking body 222 to achieve the transmission connection with the execution assembly, thereby effectively reducing the probability of accidental contact with the force-bearing member 2211.

[0071] Optionally, as Figure 5-7 As shown, in some embodiments, the end cap 223 is provided with a through hole 2230, and the plate member 2211b is arranged opposite to the through hole 2230, so that the execution assembly of the blood gas analyzer 1 can pass through the through hole 2230 and abut against the plate member 2211b, thereby transmitting the external force to the plate member 2211b. With such a setting, on the premise of ensuring the smooth docking of the liquid passage valve 22 with the execution assembly, it can also reduce the probability of accidental contact with the force-bearing member 2211 to a certain extent. Further, in some embodiments, the through hole 2230 is arranged on the end wall of the end cap 223 opposite to the valve body 2201, and the ratio of the area of the through hole 2230 to the total area of the end face of the end wall is less than or equal to 0.2 - 0.5. With such a setting, it can further reduce the probability of accidental contact with the force-bearing member 2211, thereby effectively reducing the probability of accidental opening or closing of the liquid passage valve 22.

[0072] Optionally, as Figure 4As described above, in some embodiments, the kit 20 further includes a channel assembly 250 disposed on the cartridge body 21. Among them, at least a part of the channel assembly 250 is located in the space between the force-bearing member 2211 and the movable member 2210. For example, at least a part of the channel assembly 250 can be disposed on the side of the plate member 2211b facing the valve body 2201.

[0073] Specifically, in some embodiments, the assembly process between the force-bearing member 2211 and the movable member 2210 is usually behind the assembly process of the channel assembly 250 and the docking process between the channel assembly 250 and the first channel port 220a. In this way, it can effectively prevent accidental contact with the switch assembly 221 during the assembly process of the channel assembly 250 (for example, the docking process between the adapter pipe member 252 and the first channel port 220a and the docking process between the adapter pipe member 252 and the conduit member 251), resulting in accidental connection of the liquid channel 220g, and further causing the risk of air flowing into the liquid bag 24 or leakage of the liquid in the liquid bag 24. Therefore, setting at least a part of the channel assembly 250 between the force-bearing member 2211 and the movable member 2210 can provide spatial conditions for the sequence of the assembly process between the force-bearing member 2211 and the movable member 2210 and the assembly process of the channel assembly 250, thereby effectively reducing the risk of air flowing into the liquid bag 24 or leakage of the liquid in the liquid bag 24 during the docking process between the channel assembly 250 and the first channel port 220a.

[0074] Furthermore, as Figure 11-13 shown, in some embodiments, the channel assembly 250 includes an adapter pipe member 252 and a conduit member 251. Specifically, the adapter pipe member 252 is a component for docking the second channel port 220b with the conduit member 251, that is, the adapter pipe member 252 is disposed between the second channel port 220b and the conduit member 251, and the adapter pipe member 252 is docked with the second channel port 220b and also docked with the conduit member 251 to enable the docking of the second channel port 220b with the conduit member 251. Among them, the conduit member 251 is a component for forming a complex fluid channel and is used to dock with the sample test card of the blood gas analyzer 1. Therefore, docking the second channel port 220b with the conduit member 251 through the adapter pipe member 252 can effectively reduce the assembly complexity between the liquid passing valve 22 and the conduit member 251, and further effectively improve the assembly efficiency between the liquid passing valve 22 and the conduit member 251. The adapter pipe member 252 is located on the side of the plate member 2211b facing the valve body 2201, so it can provide spatial conditions for the sequence of the assembly process between the force-bearing member 2211 and the movable member 2210 and the assembly process of the channel assembly 250, thereby effectively reducing the risk of air flowing into the liquid bag 24 or leakage of the liquid in the liquid bag 24 during the docking process between the channel assembly 250 and the first channel port 220a.

[0075] Optionally, as Figure 11-13 shown, in some embodiments, the kit 20 includes a ventilation valve 23 and a plurality of liquid communication valves 22. Each liquid communication valve 22 is respectively docked with a corresponding liquid bag 24. For example, the plurality of liquid communication valves 22 can be respectively docked with corresponding calibration liquid bags and are respectively docked with a conduit member 251 through an adapter member 252. Among them, the ventilation valve 23 is disposed on the box body 21. The ventilation valve 23 is docked with the conduit member 251 through the adapter member 252, and the ventilation valve 23 is provided with a gas passage that can be selectively communicated or closed to at least selectively communicate or close the flow passage in the adapter member 252. Thus, when it is necessary to clean the fluid passages in the adapter member 252 and the conduit member 251, the execution assembly can control the ventilation valve 23 to open so that air enters the fluid passages in the adapter member 252 and the conduit member 251, and the residual liquid in the adapter member 252 and the conduit member 251 can be blown away by blowing, thereby effectively improving the cleaning efficiency.

[0076] Specifically, in some embodiments, the adapter member 252 includes an extension section 2521 and a plurality of connection sections 2520. Among them, the plurality of connection sections 2520 are respectively connected to the extension section 2521. The plurality of connection sections 2520 are respectively docked with the corresponding liquid communication valves 22 and the ventilation valve 23. The extension section 2521 straddles the open ends of a plurality of docking bodies 222, and the plurality of connection sections 2520 and at least a part of the extension section 2521 are disposed in the corresponding accommodation spaces 222b. For example, in some embodiments, the side wall of the docking body 222 is provided with an open slot 2223. The open slot 2223 communicates the accommodation space 222b with the outside of the docking body 222. Among them, the extension section 2521 of the adapter member 252 sequentially passes through the corresponding docking bodies 222 along the corresponding open slots 2223 and is respectively connected to the connection sections 2520 located in the corresponding accommodation spaces 222b. And, the extension section 2521 is also in limit cooperation with the open slot 2223, so that the adapter member 252 can be effectively prevented from shaking relative to the valve body 2201, thereby effectively improving the docking stability between the adapter member 252 and the first channel opening 220a. The extension section 2521 can be spaced from the plate member 2211b, and the spaced distance is greater than or equal to the stroke length of the plate member 2211b.

[0077] Optionally, in some embodiments, the kit 20 further includes a plurality of docking rubber plugs 224. Among them, the connection section 2520 is docked with the second channel opening 220b through the plurality of docking rubber plugs 224, so that the docking sealing performance between the connection section 2520 and the second channel opening 220b can be effectively improved.

[0078] The above are only the implementation manners of the present application, and do not thus limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall similarly be included in the patent protection scope of the present application.
