[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] References to "embodiments" herein 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 the 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.

[0024] Next, we'll discuss a blood gas analysis device that utilizes blood gas analysis technology. Blood gas analysis refers to a technique used in blood gas analysis equipment to measure the H+ concentration and dissolved gases (primarily CO2, O2, etc.) in a blood sample to understand a person's respiratory function and acid-base balance. This technique directly reflects lung ventilation function and its acid-base balance, and the specimen used is typically a blood sample.

[0025] Among them, blood gas analysis equipment can directly measure more than 50 indicators, such as the main indicators of blood gas: PO2, PCO2, CaO2, SaO2, TCO2, P 50 etc.; main indicators of acid-base balance: pH, PCO2, TCO2, ABE, SBE and electrolytes, etc.

[0026] See also Figures 1 to 3 , Figure 1 is a schematic structural diagram of a blood gas analysis device 1000 in some embodiments of the present application. Figure 2 yes Figure 1 A schematic diagram of the structure of the blood gas analysis device 1000 in the embodiment is shown. Figure 3 It is a schematic block diagram of the structure of the blood gas analysis device 1000 in some embodiments of the present application.

[0027] The blood gas analysis device 1000 may include a first detection assembly 100, a second detection assembly 200, a reagent reagent 300, and a mounting bracket 400. The first detection assembly 100, the second detection assembly 200, and the reagent reagent 300 may be detachably mounted on the mounting bracket 400. Alternatively, the blood gas analysis device 1000 may include only the first detection assembly 100 or the second detection assembly 200.

[0028] The first detection component 100 is configured to use electrochemical methods or AC impedance methods to complete the measurement of at least some of the above parameters, and it can also be called a "blood gas biochemistry test card" or "test card". The second detection component 200 is configured to use optical measurement methods to measure parameters such as blood oxygen saturation, or it can also measure blood oxygen saturation by measuring oxygen partial pressure. The second detection component 200 can also be called an "oximeter" or "oxygen partial pressure meter" in some application scenarios. Among them, the first detection component 100 can be used for blood gas detection, and the second detection component 200 can be used for blood oxygen detection.

[0029] One or more reagent packs (S1, S2, S3, S4, etc.) may be provided in the test kit 300, and at least one recovery pack w0 may further be provided. Each reagent pack may be equipped with functional reagents such as calibration liquid, quality control liquid, flushing liquid or disinfectant. The functional reagents in each of the above reagent packs can be selectively transported to the first detection component 100 to perform operations such as cleaning and calibration on the liquid circuit in the first detection component 100, thereby ensuring the accuracy of the detection data of the first detection component 100. The liquid flowing out of the first detection component 100 can be transported to the second detection component 200. The liquid flowing out of the second detection component 200 can reach the recovery pack w0 via a liquid pipeline. It can be understood that the recovery pack w0 generally refers to a device / structure for carrying liquid, such as a bag-shaped body, a liquid bag, a cavity / trough body provided inside the test kit 300, or a box body, but is not limited thereto. Of course, in other embodiments, the blood gas analysis device 1000 may include one of the first detection component 100 and the second detection component 200, and the functional reagents in each of the above reagent packages may be selectively delivered to the first detection component 100 or the second detection component 200.

[0030] The first detection component 100 can be docked with or separated from the reagent kit 300 . During docking, the functional reagents in each reagent package can be selectively delivered to the first detection component 100 .

[0031] The second detection component 200 can be docked with or separated from the reagent kit 300 . During docking, the functional reagents in each reagent package can be selectively delivered to the second detection component 200 .

[0032] When the first detection component 100 and the second detection component 200 are respectively docked with the reagent kit 300, the functional reagents in each reagent pack can be selectively delivered to the first detection component 100, and the liquid flowing out of the first detection component 100 can be delivered to the second detection component 200. The liquid flowing out of the second detection component 200 can reach the recovery bag w0 through the liquid pipeline.

[0033] The mounting bracket 400 is configured to assemble the first detection component 100, the second detection component 200, and the reagent kit 300 to form the overall structure of the blood gas analysis device 1000. In other words, the mounting bracket 400 can be a supporting bracket for the blood gas analysis device 1000. On the one hand, it can carry the first detection component 100, the second detection component 200, and the reagent kit 300, and on the other hand, it can serve as a carrier for the movement of the blood gas analysis device 1000 as a whole. Among them, the first detection component 100, the second detection component 200, and the reagent kit 300 can be detachably assembled with the mounting bracket 400 respectively to facilitate individual replacement. Of course, the first detection component 100 and the second detection component 200 can also be non-detachably assembled with the mounting bracket 400.

[0034] See also Figures 4 to 6 , Figure 4 is a schematic structural diagram of the first detection component 100 in some embodiments of the present application, Figure 5 yes Figure 4 A structural diagram of the first detection component 100 from another perspective in the embodiment, Figure 6 yes Figure 4 Schematic diagram of the cross-sectional structure of the first detection component 100 in the embodiment.

[0035] The first detection assembly 100 may include a detection element 110, a first liquid circuit 120, and a first interface 130. The first liquid circuit 120 and the first interface 130 are connected. The detection element 110 is used to detect the liquid in the first liquid circuit 120 to obtain a detection signal. Optionally, the first detection assembly 100 may further include a housing 140. The detection element 110 and the first liquid circuit 120 are disposed within the housing 140. The first interface 130 is disposed on the housing 140 and is connected to the first liquid circuit 120 within the housing 140. The detection element 110 is disposed within the housing 140 and exposed to the first liquid circuit 120 for detecting the liquid in the first liquid circuit 120 to obtain a detection signal.

[0036] In one embodiment, the housing 140 may further include a connection terminal 150, which is electrically connected to the detection element 110 and exposed to the exterior of the housing 140. The connection terminal 150 is configured to electrically connect to the processing circuit of the blood gas analysis device 1000 to transmit the detection signal. The connection terminal 150 may be electrically connected to the processing circuit via a plug-in pin or a spring clip.

[0037] In one embodiment, the first detection assembly 100 has a third interface 160 spaced apart from the first interface 130, and the third interface 160 is in communication with the first interface 130 via the first fluid path 120. In other words, the first interface 130 and the third interface 160 can be configured as the inlet and outlet of the first fluid path 120, such that liquid can flow from the first interface 130 to the first fluid path 120, and liquid in the first fluid path 120 can flow out through the third interface 160.

[0038] One end of the first interface 130 is connected to the first liquid circuit 120, and the other end is configured to be docked with the reagent box 300. One end of the third interface 160 is connected to the first liquid circuit 120, and the other end is configured to be docked with the reagent box 300. Optionally, the ends of the first interface 130 and the third interface 160 that dock with the reagent box 300 have a conical depression or a conical protrusion to guide the first interface 130 and the third interface 160 to dock with the reagent box 300. Figure 5 As shown, the ends of the first interface 130 and the third interface 160 that dock with the reagent reagent 300 have tapered recesses.

[0039] In one embodiment, a first positioning member 170 is provided on the housing 140 of the first detection component 100 for positioning the first detection component 100 and the reagent kit 300 when docking. The first positioning member 170 may be a convex column or a slot formed on the housing 140. Figure 5 As shown, the first positioning member 170 is a slot formed on the housing 140. There can be one or more first positioning members 170.

[0040] Preferably, the first interface 130 , the third interface 160 and the first positioning member 170 are arranged on the same side of the housing 140 , so as to facilitate docking of the first detection component 100 and the reagent kit 300 .

[0041] See again Figure 2 and Figure 3, the test kit 300 can have a cavity 310, a second fluid circuit 320 and a second interface 330. The cavity 310 is configured to place liquid packets such as the above-mentioned reagent packs and recovery packs, one end of the second fluid circuit 320 is configured to be connected to the liquid packet, and the other end is configured to be connected to the second interface 330. Wherein, the test kit 300 and the first detection component 100 can be docked or separated so that the second interface 330 and the first interface 130 are connected or separated. When the second interface 330 and the first interface 130 are connected, the second fluid circuit 320 is connected to the first fluid circuit 120 so that the reagent in the liquid packet can reach the first fluid circuit 120. It is understandable that one end of the second fluid circuit 320 is configured to be connected to the reagent pack, and the other end is configured to be connected to the second interface 330. When the second interface 330 and the first interface 130 are connected, the second fluid circuit 320 is connected to the first fluid circuit 120 so that the reagent in the reagent pack can reach the first fluid circuit 120.

[0042] In one embodiment, the reagent kit 300 may be provided with a sampling element 301. The sampling end of the sampling element 301 is configured to selectively collect reagents from a reagent pack placed in the chamber 310, or the sampling end of the sampling element 301 is configured to collect liquids outside the reagent kit 300 (e.g., a blood sample in a syringe or capillary tube). That is, the sample outlet end of the sampling element 301 is connected to the second interface 330, that is, the sampling element 301 can be configured to constitute a portion of the second liquid path 320 described above.

[0043] The reagent kit 300 may include a first connecting tube 340, one end of which is connected to the reagent pack and the other end of which is connected to the sampling end of the sampling element 301. The first connecting tube 340 is configured to constitute another portion of the second fluid path 320. When the sampling element 301 collects liquid from the reagent pack within the reagent kit 300, the first connecting tube 340 and the sampling element 301 cooperate to form the second fluid path 320. When the sampling element 301 collects liquid from outside the reagent kit 300, the sampling element 301 forms the second fluid path 320.

[0044] In one embodiment, the reagent kit 300 may further include a second connecting tube 350, through which the sample outlet of the sampling element 301 may be connected to the second interface 330. Specifically, one end of the second connecting tube 350 is used to connect to the sample outlet of the sampling element 301, and the other end is used to connect to the second interface 330. The second connecting tube 350 is configured to constitute another portion of the second fluid path 320. When the sampling element 301 collects liquid from a reagent pack within the reagent kit 300, the first connecting tube 340, the sampling element 301, and the second connecting tube 350 cooperate to form the second fluid path 320. When the sampling element 301 collects liquid from outside the reagent kit 300, the sampling element 301 and the second connecting tube 350 cooperate to form the second fluid path 320.

[0045] In one embodiment, the reagent kit 300 further comprises a fourth interface 360 ​​and a third connecting tube 370, wherein the fourth interface 360 ​​is spaced apart from the second interface 330. One end of the third connecting tube 370 is configured to communicate with the fourth interface 360, and the other end is connected to a recovery bag disposed within the chamber 310. When the second interface 330 is in communication with the first interface 130, the fourth interface 360 ​​is in communication with the third interface 160. The third connecting tube 370 can be configured to constitute a portion of the second liquid path 320 described above.

[0046] The ends where the first interface 130 and the second interface 330 meet have a conical depression or a conical protrusion, and the ends where the third interface 160 and the fourth interface 360 ​​meet have a conical depression or a conical protrusion. Alternatively, the ends where the second interface 330 and the first interface 130 meet have a conical depression or a conical protrusion, and the ends where the fourth interface 360 ​​and the third interface 160 meet have a conical depression or a conical protrusion.

[0047] As previously mentioned, the ends where the first interface 130 and the second interface 330 mate have a conical depression, while the ends where the second interface 330 and the first interface 130 mate have a conical protrusion. The ends where the third interface 160 and the fourth interface 360 ​​mate have a conical depression, while the ends where the fourth interface 360 ​​and the third interface 160 mate have a conical protrusion. Of course, the above interfaces can also be mated in other ways, which will not be described in detail.

[0048] Preferably, the first connecting tube 340, the second connecting tube 350, the third connecting tube 370 and the sampling element 301 can be integrated on the reagent kit 300 to serve as a pipeline for liquid flow, and can be disassembled together with the reagent kit 300, that is, the liquid pipeline can be replaced simultaneously when the reagent kit 300 is replaced.

[0049] Among them, the first connecting tube 340, the second connecting tube 350, and the third connecting tube 370 can be connecting tubes, plug-in tubes, or a combination of connecting tubes and plug-in tubes, etc. The connecting tubes can be hoses such as plastic tubes, rubber tubes, silicone tubes, etc., the plug-in tubes can be hard tubes such as steel pipes, PVC tubes, etc., and the plug-in tubes can also be hoses, etc.

[0050] Furthermore, the sampling end of the sampling element 301 is used to selectively collect reagents from the reagent pack or liquids outside the reagent kit 300, that is, the sampling position of the sampling end of the sampling element 301 can be changed. When the sampling element 301 collects the reagents from the reagent pack, the reagents from the reagent pack can reach the first detection component 100 or the second detection component 200 via the sampling element 301. Optionally, the sampling end of the sampling element 301 can be switched between a first position, a second position, and a third position. In the first position, the sampling element 301 is generally vertical, and its sampling end can selectively collect reagents from the reagent pack; in the second position, the sampling element 301 is generally inclined relative to the horizontal plane, and its sampling end can collect liquids from an external container such as a syringe; in the third position, the sampling element 301 is generally parallel to the horizontal plane, and its sampling end can collect liquids from an external container such as a capillary tube.

[0051] In one embodiment, the blood gas analysis device 1000 may include a valve assembly 500 that can be docked with or detached from the reagent kit 300. The valve assembly 500 may include multiple valves (V1 to V4, etc.), configured to control the selective delivery of the aforementioned multiple functional liquids to the sampling element 301. The valve assembly 500 may be connected to the sampling element 301 via a connecting pipeline, etc. The connecting pipeline connecting the valve assembly 500 to the sampling element 301 may be a soft plastic hose or other pipe fitting. The valve assembly 500 may include valves such as a solenoid valve, a multi-way valve, and an air valve.

[0052] The multiple valves of the valve assembly 500 each have an input end, each of which is used to connect to a corresponding reagent pack to selectively control the outflow of liquid from the multiple reagent packs. The multiple valves can share a single output end, so that liquid from multiple reagent packs can selectively flow out from one of the output ends. One end of the first connecting tube 340 is connected to the output end of the valve assembly 500, and the other end is connected to the input end of the sampling element 301, so that liquid from multiple reagent packs can selectively reach the sampling element 301.

[0053] Optionally, the blood gas analysis device 1000 may also include a drive assembly 600 for driving the flow of liquid in the sampling element 301, an adjustment assembly for adjusting the sampling position of the sampling element 301, a display electrically connected to the processing circuit board, a printer, a keyboard, a code scanning device and other input and output devices (not shown in the figure). Among them, the drive assembly 600 is used to drive the sampling element 301 to take a sample, and can be used to guide the liquid to flow to the recovery bag via the first detection component 100 or the second detection component 200. The drive assembly 600 can also be used to drive the reagent of the reagent pack to the sampling element 301, and can be transported to the first detection component 100 or the second detection component 200 via the sampling element 301 under the drive of the drive assembly 600.

[0054] The driving assembly 600 may be a hose-based peristaltic pump, which can squeeze the third connecting tube 370 and promote the flow of liquid in the third connecting tube 370 during operation.

[0055] The processing circuit is configured to electrically connect to the detection element of the first detection assembly 100 to receive detection signals from the first detection assembly 100 when connected. The blood gas analysis device 1000 can control the operating states of components such as the valve assembly 500, the drive assembly 600, and the adjustment assembly based on the received detection signals. The processing circuit can also be configured to establish a signal connection with the second detection assembly 200 to receive detection signals from the second detection assembly 200 when connected.

[0056] It should be noted that the terms "first," "second," "third," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Therefore, a feature identified as "first," "second," or "third" may explicitly or implicitly include one or more of the aforementioned features.

[0057] In one embodiment, the reagent kit 300 may be provided with a liquid conduit exposed outside the cavity 310, which constitutes another portion of the second liquid conduit 320. Liquid flowing out of the first liquid conduit 120 flows through the liquid conduit and then into the cavity 310. The second detection assembly 200 is configured to detect liquid in the liquid conduit exposed outside the cavity 310. In other words, the liquid conduit may be a portion of the third connecting tube 370, i.e., the third connecting tube 370 is partially exposed outside the cavity 310 to serve as the liquid conduit, allowing the second detection assembly 200 to detect liquid in the portion of the third connecting tube 370 exposed outside the cavity 310.

[0058] When the blood gas analysis device 1000 eliminates the first detection assembly 100, the second connecting tube 350 and the third connecting tube 370 can be combined into a single connecting tube, with one end of the combined connecting tube connected to the sample outlet of the sampling element 301 and the other end connected to the recovery bag within the cavity 310. In this case, the connecting tube formed by the combined second connecting tube 350 and the third connecting tube 370 can be partially exposed outside the cavity 310, allowing the second detection assembly 200 to detect liquid in the portion of the connecting tube exposed outside the cavity 310.

[0059] In one embodiment, a docking receptacle 302 is provided on the outer wall of the cavity 310. The second interface 330 and the fourth interface 360 ​​can be provided on the docking receptacle 302 and are respectively used to connect to or disconnect from the first interface 130 and the third interface 160. As previously mentioned, one end of the third connecting tube 370 is connected to the fourth interface 360, and the other end is connected to the recovery bag in the cavity 310. In other words, the third connecting tube 370 is partially located between the cavity wall of the cavity 310 and the docking receptacle 302.

[0060] See also Figure 7 and Figure 8 , Figure 7 is a schematic structural diagram of the reagent kit 300 in some embodiments of the present application, Figure 8 yes Figure 7 A schematic diagram of a partial cross-sectional structure of the reagent kit 300 in the embodiment.

[0061] The sampling element 301 and docking station 302 are both located outside the cavity 310 of the reagent kit 300. The sample outlet end of the sampling element 301 is connected to the docking station 302 and can rotate relative to the docking station 302 to change the sampling position of the sampling end of the sampling element 301, thereby allowing the sampling end of the sampling element 301 to selectively collect reagents from the reagent pack or liquid outside the reagent kit 300. The sample outlet end of the sampling element 301 can be inserted into one end of the docking station 302 and can rotate relative to the docking station 302. The docking station 302 can be fixed to the outside of the cavity 310 by means of a snap connection, screw connection, or welding.

[0062] In one embodiment, a pipe 303 is formed on one side of the docking seat 302 close to the cavity 310, one end of the second interface 330 is connected to the pipe 303, and the other end is used to dock or separate with the first interface 130; one end of the fourth interface 360 ​​is connected to the pipe 303, and the other end is used to dock or separate with the third interface 160.

[0063] Among them, the second connecting tube 350 is arranged in the pipeline 303, one end of which is passed through or embedded in the second interface 330, and the other end is used to communicate with the sample outlet end of the sampling element 301, so that the liquid collected by the sampling element 301 can reach the first detection component 100 via the second connecting tube 350. Optionally, the sample outlet end of the sampling element 301 can be inserted into the docking seat 302 and connected to the pipeline 303, and the other end of the second connecting tube 350 can be docked and connected with the sample outlet end of the sampling element 301. The third connecting tube 370 is partially arranged in the pipeline 303, one end of which is passed through or embedded in the fourth interface 360, and the other end is used to communicate with the recovery bag in the cavity 310, so that the liquid in the first detection component 100 can reach the recovery bag in the cavity 310 via the third connecting tube 370. Optionally, the pipe 303 is located between the docking seat 302 and the cavity wall of the cavity 310 , and the third connecting pipe 370 is partially located between the docking seat 302 and the cavity wall of the cavity 310 .

[0064] Of course, in other embodiments, the docking station 302 is disposed outside the cavity wall of the chamber 310, and the conduit 303 is formed inside the docking station 302 and is respectively connected to the second interface 330 and the fourth interface 360. The sample outlet end of the sampling element 301 can be inserted into the docking station 302 and connected to the conduit 303, thereby allowing the liquid collected by the sampling element 301 to reach the first detection assembly 100 via the conduit 303. One end of the third connecting tube 370 can be inserted into the docking station 302 and connected to the conduit 303, thereby allowing the liquid in the first detection assembly 100 to reach the third connecting tube 370 via the conduit 303.

[0065] In one embodiment, a second positioning member 390 is provided in the area where the second interface 330 and the fourth interface 360 ​​are located on the docking station 302 for positioning and docking with the first detection assembly 100. The second positioning member 390 can be a protrusion or a slot formed on the docking station 302 and is configured to cooperate with the first positioning member 170 to enable docking between the first detection assembly 100 and the reagent kit 300. There can be one or more second positioning members 390.

[0066] It can be understood that when one of the first positioning member 170 and the second positioning member 390 is a protruding column and the other is a slot, the first positioning member 170 and the second positioning member 390 are arranged in a one-to-one correspondence.

[0067] See also Figure 9 and Figure 10 , Figure 9 is a schematic structural diagram of the mounting bracket 400 in some embodiments of the present application. Figure 10 yes Figure 9 Schematic diagram of partial structural disassembly of the mounting bracket 400 in the embodiment.

[0068] The mounting bracket 400 has a first mounting position for detachably mounting the first detection assembly 100 and a second mounting position for placing the reagent cartridge 300. The first detection assembly 100 and the reagent cartridge 300 can be docked or detached to connect or disconnect the first detection assembly 100 and the reagent cartridge 300; when connected, the reagent in the reagent cartridge 300 can reach the first detection assembly 100.

[0069] Of course, in other embodiments, the mounting bracket 400 may further include a third mounting position for removably mounting the second detection assembly 200. The reagent cartridge 300 may include a liquid conduit exposed outside the mounting bracket 400. This liquid conduit may be a portion of the aforementioned third connecting tube 370. Liquid flowing out of the first detection assembly 100 flows through this liquid conduit and into the reagent cartridge 300. The second detection assembly 200 is used to detect the liquid in the liquid conduit exposed outside the mounting bracket 400.

[0070] Specifically, the mounting bracket 400 may include a fixed bracket 400 a and a movable bracket 400 b , wherein the movable bracket 400 b is disposed on the fixed bracket 400 a and is movable relative to the fixed bracket 400 a .

[0071] The fixing bracket 400a has a cavity 401, which is configured to form a second installation position for placing the reagent kit 300. One end of the cavity 401 is open, namely, a take-out port 402, and the reagent kit 300 can be moved into or out of the cavity 401 through the take-out port 402.

[0072] It should be noted that Figure 9 The X, Y, and Z directions of the mounting bracket 400 are shown in the figure, mainly to facilitate the corresponding description in the following text. Among them, the X, Y, and Z directions can be directions perpendicular to each other. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship and movement of the various components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0073] Alternatively, the X-direction can be defined as the direction in which the reagent cartridge 300 moves into the cavity 401, with the direction opposite to the X-direction being the direction in which the reagent cartridge 300 moves out of the cavity 401. The Z-direction can be defined as the direction in which the first detection assembly 100 moves away from the mounting bracket 400 to separate from the reagent cartridge 300, with the direction opposite to the Z-direction being the direction in which the first detection assembly 100 moves toward the mounting bracket 400 to dock with the reagent cartridge 300. In other words, the first detection assembly 100 can move in the Z-direction to separate from the reagent cartridge 300, or it can move in the direction opposite to the Z-direction to dock with the reagent cartridge 300.

[0074] In one embodiment, the fixed bracket 400a may include a top plate 410 and a bottom plate 420 that are arranged opposite to each other, and a side plate 430 that is arranged between the top plate 410 and the bottom plate 420. The top plate 410, the bottom plate 420, and the side plate 430 can each be in the shape of a plate, or of course, other shapes, which will not be described in detail. Among them, the top plate 410, the bottom plate 420, and the side plate 430 are jointly arranged to form a cavity 401 having a take-in and put-out port 402. The top plate 410, the bottom plate 420, and the side plate 430 can be an integral structure. Of course, in other embodiments, the top plate 410, the bottom plate 420, and the side plate 430 can be separately molded and assembled into a fixed bracket 400a having a cavity 401.

[0075] The top plate 410 and the bottom plate 420 are spaced apart, and their surfaces are generally parallel. That is, the top plate 410 and the bottom plate 420 are spaced apart in the Z direction, which can be used to define the height of the fixed bracket 400a in the Z direction. The side plates 430 are disposed between the top plate 410 and the bottom plate 420, and the side plates 430 are bent and connected to the top plate 410 and the bottom plate 420 on opposite sides in the Z direction. Preferably, the side plates 430 can be perpendicular to the top plate 410 and the bottom plate 420 on opposite sides in the Z direction. It should be understood that, unless otherwise defined in the specific context, the use of the terms "substantially" or "generally" herein in relation to numerical quantities or other quantifiable relationships (e.g., perpendicularity or parallelism) should be understood to indicate a quantity within ±10%. Thus, for example, lines that are generally perpendicular to each other can form an angle between 81° and 99°.

[0076] In one embodiment, the side panels 430 may include a first side panel 431, a second side panel 432, and a third side panel 433, which are connected in a bent manner. The second side panel 432 is disposed opposite the access opening 402 to limit the travel of the reagent reagent 300 into the cavity 401. The first side panel 431 and the third side panel 433 are disposed opposite each other. Optionally, the top panel 410, the bottom panel 420, the second side panel 432, and the third side panel 433 are located on the same side of the first side panel 431, and the ends of the top panel 410, the bottom panel 420, the second side panel 432, and the third side panel 433 facing away from the first side panel 431 are arranged to form the access opening 402. In some embodiments, the terms "first side panel," "second side panel," "third side panel," and "side panel" may be interchangeable. For example, in one embodiment, the "first side panel" in other embodiments may be referred to as the "second side panel" or "side panel," and accordingly, the "second side panel" in other embodiments may be referred to as the "first side panel" or "side panel."

[0077] In one embodiment, the top plate 410 may be provided with a first escape opening 411 that connects to the cavity 401. Specifically, the first escape opening 411 extends through two opposite sides of the top plate 410 in the Z direction. When the reagent cartridge 300 is moved into the cavity 401, the docking station 302 on the reagent cartridge 300 may be exposed through the first escape opening 411, allowing the interface on the docking station to dock with the interface of the first detection assembly 100, thereby allowing the liquid collected by the sampling element 301 to reach the first detection assembly 100. Specifically, the second interface 330 and the fourth interface 360 ​​on the docking station 302 may be exposed through the first escape opening 411 to connect or disconnect with the first interface 130 and the third interface 160 of the first detection assembly 100. In other words, the first escape opening 411 may serve as an escape passage for the docking of the first detection assembly 100 and the reagent cartridge 300, allowing the first fluid path 120 of the first detection assembly 100 and the second fluid path 320 of the reagent cartridge 300 to connect via the first escape opening 411. When the reagent box 300 is moved into the cavity, the docking seat 302 and the second positioning member 390 thereon are exposed from the first avoidance opening 411 , so as to facilitate accurate positioning between the first detection component 100 and the reagent box 300 .

[0078] Of course, in other embodiments, the first avoidance opening 411 may also be provided at other locations on the mounting bracket 400, which will not be described in detail. Furthermore, the first avoidance opening 411 may extend through opposite sides of the top plate 410 in the direction in which the reagent reagent 300 is moved into the cavity 401, i.e., in the X-direction, so that the end of the first avoidance opening 411 facing away from the first side plate 431 communicates with the access opening 402, thereby avoiding the docking station 302 during the process of moving the reagent reagent 300 into or out of the cavity 401.

[0079] In one embodiment, the liquid pipeline on the reagent cartridge 300 exposed outside the mounting bracket 400 can be exposed through the first avoidance opening 411. Correspondingly, a third mounting position is formed on the top plate 410 and located outside the cavity 401. Optionally, the third mounting position is adjacent to the first avoidance opening 411. That is, the second detection assembly 200 can be disposed on the top plate 410 and adjacent to the first avoidance opening 411 to detect the liquid in the liquid pipeline exposed through the first avoidance opening 411.

[0080] In one embodiment, the first side plate 431 is provided with a second escape opening 412 that communicates with the cavity 401. Specifically, the second escape opening 412 extends through two opposite sides of the first side plate 431 in the X direction. When the reagent cartridge 300 is inserted into the cavity 401, the sampling element 301 on the reagent cartridge 300 is exposed through the second escape opening 412, allowing the sampling element 301 to collect liquid from the outside of the reagent cartridge 300.

[0081] Furthermore, the second avoidance opening 412 can be connected to the side of the first side plate 431 adjacent to the top plate 410, so that the second avoidance opening 412 can communicate with the first avoidance opening 411, thereby avoiding the joint between the sampling element 301 and the docking seat 302 when the reagent kit 300 is moved into the cavity 401.

[0082] The movable bracket 400b is provided on the top plate 410 and has a receiving cavity 403, which is configured to form a first mounting position for detachably assembling the first detection component 100. When the test kit 300 moves into the cavity 401, the movable bracket 400b can move relative to the fixed bracket 400a so that the first detection component 100 can be docked with the test kit 300. In other words, the first detection component 100 can move relative to the fixed bracket 400a or the test kit 300 under the drive of the movable bracket 400b. Optionally, the movable bracket 400b can be a frame structure with an opening facing the top plate 410, and its opening is connected to the receiving cavity 403. The first interface 130 and the third interface 160 of the first detection component 100 can be exposed outside the movable bracket 400b from the above-mentioned opening to achieve docking or separation with the second interface 330 and the fourth interface 360. The movable bracket 400b can move relative to the fixed bracket 400a in the Z direction or the opposite direction of the Z direction under the action of external force, so that the first detection component 100 can be docked with or separated from the reagent kit 300.

[0083] In one embodiment, the movable support 400b may include a first support 450 that is movable relative to the fixed support 400a in a first direction, and a second support 460 that is movable relative to the fixed support 400a in a second direction. When the first support 450 moves relative to the fixed support 400a in the first direction, the first detection assembly 100 can move into or out of the first support 450. When the second support 460 moves relative to the fixed support 400a in the second direction, the first detection assembly 100 can dock with or detach from the reagent cartridge 300. The first direction may be the Y direction and its opposite direction, and the second direction may be the Z direction and its opposite direction.

[0084] The first bracket 450 has a receiving cavity 403 and is slidably connected to the second bracket 460. The movable bracket 400b may further include a power assembly 470 disposed on the second bracket 460, the power assembly 470 being configured to drive the first bracket 450 to move relative to the second bracket 460 in a first direction.

[0085] In one embodiment, a guide rod 404 is provided on the top plate 410, and a second bracket 460 is sleeved on the guide rod 404 and can move relative to the guide rod 404 along the axial direction of the guide rod 404. The axial direction of the guide rod 404 is substantially parallel to the Z direction. The guide rod 404 can be fixedly connected to the top plate 410 by screwing, plugging, snapping, welding, or bonding. Furthermore, the second bracket 460 can drive the first bracket 450 so that the first bracket 450 can move relative to the guide rod 404 along the axial direction of the guide rod 404, thereby enabling the first detection assembly 100 to dock or detach with the reagent kit 300.

[0086] In one embodiment, the second bracket 460 may be a box structure having a hollow space, with a channel 461 extending through the second bracket 460. The first bracket 450 may move relative to the second bracket 460 along the channel 461 to facilitate access to and placement of the first detection assembly 100. The direction of movement of the first bracket 450 is substantially perpendicular to the direction in which the axis of the guide rod 404 extends.

[0087] The second bracket 460 has a test hole 462 and an avoidance hole 463 on opposite sides thereof, each of which is connected to the channel 461. When the first detection component 100 is located in the channel 461, the connection terminal 150 of the first detection component 100 can be exposed from the test hole 462 for electrical connection with the processing circuit; the first interface 130 and the third interface 160 of the first detection component 100 can be exposed from the avoidance hole 463 for connection or separation with the second interface 330 and the fourth interface 360 ​​on the docking station 302. Of course, in other embodiments, when the connection terminal 150, the first interface 130, and the third interface 160 of the first detection component 100 are located on the same side, the test hole 462 and the avoidance hole 463 can be located on the same side of the second bracket 460 and connected to the channel 461. In addition, in some embodiments, when the first bracket 450 and the second bracket 460 are arranged side by side in the X direction, the second bracket 460 can cancel the above structure and only be slidably connected to the first bracket 450.

[0088] In one embodiment, the first bracket 450 may be a plate-shaped structure having a receiving cavity 403. Alternatively, other structures may be employed, which will not be described in detail. The wall of the receiving cavity 403 may have openings for accommodating the first interface 130 and the third interface 160 of the first detection component 100, as well as a window for accommodating the connection terminal 150 of the first detection component 100.

[0089] The power assembly 470 can be a motor drive mechanism or a cylinder drive structure, etc., with its output end connected to or abutting the first bracket 450 to drive the first bracket 450 to move in the Y direction or the opposite direction of the Y direction. For example, the output end of the power assembly 470 can be a roller that abuts on the first bracket 450, and the rotation of the roller can drive the first bracket 450 to move. For another example, the output end of the power assembly 470 can be a gear, and the first bracket 450 is provided with a rack that meshes with the gear. The gear and rack cooperate to drive the first bracket 450 to move. Of course, the cooperation between the power assembly 470 and the first bracket 450 is not limited to this.

[0090] In one embodiment, the power assembly 470 may include a positioning member 471 assembled and connected to the second bracket 460, and a driving member 472 disposed on the positioning member 471. The positioning member 471 may be assembled to a side of the second bracket 460 by means of a snap connection, welding, or screw connection, avoiding the passage 461 of the second bracket 460. The driving member 472 may be a drive motor assembled on the positioning member 471, and its output shaft is used to drive the first bracket 450 to move relative to the second bracket 460 in the Y direction.

[0091] In the blood gas analysis device provided by the embodiment of the present application, when the test kit is moved into the cavity of the mounting bracket, the sampling element on the test kit can be exposed from the second avoidance port to the mounting bracket, so that the sampling element can collect the liquid outside the test kit. At the same time, the docking seat on the test kit is exposed from the first avoidance port to the mounting bracket, so that the second interface and the fourth interface on the docking seat can be exposed from the avoidance port to achieve connection or separation with the first interface and the third interface of the first detection component. Furthermore, the first detection component can be connected or separated with the test kit under the drive of the movable bracket, and the reagent in the test kit can reach the first detection component during docking. In addition, by partially exposing the third connecting tube of the test kit to the outside of the mounting bracket so that the second detection component can detect the liquid in the third connecting tube exposed to the outside of the mounting bracket, that is, by passing the liquid in the liquid path of the test kit through the first detection component and the second detection component in sequence, it is possible to achieve measurement of multiple parameters, thereby improving the measurement efficiency of the blood gas analysis device.

[0092] In addition, the blood gas analysis equipment provided in the embodiment of the present application can be docked or separated by setting the first detection component and the test kit to achieve detachable assembly of the first detection component and the test kit. Among them, when docking, the first liquid path of the first detection component can be connected to the second liquid path of the test kit, so that the reagent of the test kit can reach the first liquid path for blood gas detection. In addition, by setting a mounting bracket for assembling the test kit and the first detection component, and when the assembly is completed, the first detection component and the test kit can be docked or separated, and when separated, the test kit can be disassembled separately for replacement. Furthermore, the second detection component can also be assembled on the mounting bracket, and the test kit is provided with a liquid pipeline exposed to the outside, and the second detection component can perform blood oxygen detection on the liquid managed by the liquid, thereby improving the detection of the blood gas analysis equipment.

[0093] It should be noted that the terms "include," "comprise," and "have," 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 units is not limited to the listed steps or units, but may optionally include steps or units not listed, or other steps or units inherent to the process, method, product, or apparatus.

[0094] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
