[0060] This application provides a valve assembly, including: a control element, a first pipe, a first inlet, and a first outlet; wherein, the control element is used to control the first inlet to be connected to one end of the first pipe, and the other end of the first pipe to be connected to the first outlet; the first inlet is used to dock or disconnect with a first interface of a reagent kit, so that when docking, the control element controls the first inlet to obtain fluid from the reagent kit; and the first outlet is used to be connected to a docking slot of the reagent kit, so that when docking, the liquid in the reagent kit can reach the docking slot through the first outlet, and the liquid in the docking slot can reach the recycling package of the reagent kit through a second pipe of the reagent kit.

[0062] The fluid detection instrument provided in this application embodiment allows for docking or detachment of the reagent kit via a valve assembly, facilitating reagent kit replacement. Furthermore, when the valve assembly is docked with the reagent kit, a control element connects the first conduit to the docking slot, enabling liquid within the reagent kit to reach the docking slot. Simultaneously, the second conduit of the reagent kit connects to a recovery pack within the kit, allowing liquid from the docking slot to reach the recovery pack. This forms a liquid conduit, ensuring that liquid from the reagent kit reaches the recovery pack after reaching the docking slot. The liquid reaching the docking slot can be used to clean the sampling end of the sampling element on the reagent kit, maintaining the cleanliness of the sampling end and thus extending the lifespan of the reagent kit.

[0063] This application provides a liquid bag having a body and a connector. The body is used to contain liquid, and the connector is configured to control the liquid in the liquid bag to flow out of the connector or to seal the body. The connector has a pipe communicating with the internal space of the body and a seal disposed in the pipe. The seal is movable within the pipe under the action of an external force to open the pipe and returns to its initial position to seal the pipe when the external force is removed.

[0064] The liquid bag provided in this application embodiment has a pipe that connects to the internal space of the liquid bag body and a sealing element is provided in the pipe. This allows the sealing element to move inside the pipe to open or seal the pipe, eliminating the need to set a structure on the liquid bag to open or seal the pipe, thus improving the convenience of using the liquid bag.

The cleaned liquid can reach the recovery bag, so that the sampling end of the sampling element of the reagent kit can be kept clean during use.

[0069] This application provides a sample analysis device, including: a reagent kit having a sampling component, an adjustment component, and a moving component. The adjustment component is used to drive the sampling component to rotate relative to the reagent kit; the moving component is configured to correspond to the sampling component; the moving component and the sampling component are capable of docking or separating; wherein, the moving component is capable of moving relative to the sampling component between a first position and a second position, wherein in the first position the moving component is docked with the sampling component, and in the second position the moving component is separated from the sampling component; the first position corresponds to limiting the sampling component so that the sampling component can collect liquid inside the reagent kit, and the second position corresponds to releasing the limitation on the sampling component so that the adjustment component can drive the sampling component to rotate, thereby enabling the sampling component to collect liquid outside the reagent kit.

[0070] The sample analysis device provided in this application embodiment allows the moving component to move between a first position and a second position relative to the sampling component, thereby achieving different sampling states of the sampling component. Specifically, in the first position, the sampling component is limited to collect liquid inside the reagent kit; in the second position, the limitation on the sampling component is released, allowing the adjusting component to rotate the sampling component, thus enabling the sampling component to collect liquid outside the reagent kit. In other words, the moving component and the adjusting component work together to allow the sampling component to switch between different sampling states, meeting the need for variable sampling positions in the sample analysis device.

[0071] This application provides a biological sample analysis device, comprising: a drive assembly having an output shaft; a reagent storage device having a storage cavity, a first connecting pipe, a second connecting pipe, and a squeezing assembly, wherein the storage cavity is used to place a reagent pack, a cleaning pack, and a recovery pack; the first connecting pipe and the second connecting pipe are both partially embedded in the squeezing assembly; one end of the first connecting pipe is used to connect to the reagent pack, and the other end is used to connect to the recovery pack; one end of the second connecting pipe is used to connect to the cleaning pack, and the other end is used to connect to the recovery pack; wherein the drive assembly and the reagent storage device can be docked or separated, so that the output shaft docks or separates from the squeezing assembly; when docked, the output shaft can drive the squeezing assembly to synchronously squeeze the first connecting pipe and the second connecting pipe so that the liquid in the first connecting pipe or the second connecting pipe can flow.

[0072] This application provides a reagent storage device, including: a storage cavity, a first connecting pipe, a second connecting pipe, and a squeezing assembly; wherein, the storage cavity is used to place a reagent pack, a cleaning pack, and a recycling pack, and the first connecting pipe and the second connecting pipe are both partially embedded in the squeezing assembly; one end of the first connecting pipe is used to connect to the reagent pack and the other end is used to connect to the recycling pack; one end of the second connecting pipe is used to connect to the cleaning pack and the other end is used to connect to the recycling pack; the squeezing assembly is used to dock with or disengage from the output shaft of a drive assembly, so that when docking, the output shaft drives the squeezing assembly to synchronously squeeze the first connecting pipe and the second connecting pipe so that the liquid in the first connecting pipe or the second connecting pipe can flow.

[0073] The biological sample analysis device provided in this application embeds a first connecting pipe and a second connecting pipe into a squeezing assembly. This allows the squeezing assembly to simultaneously squeeze the first and second connecting pipes, enabling liquid flow within either the first or second connecting pipe. This saves the space required for a separate squeezing assembly for each connecting pipe in the reagent storage device. Furthermore, the drive assembly can be docked with or detached from the reagent storage device. Specifically, the output shaft of the drive assembly can dock with or detach from the squeezing assembly. When docked, the drive assembly can drive the squeezing assembly to perform the aforementioned operation. Conversely, the reagent storage device can be detached from the drive assembly for easy replacement of the reagent storage device.

[0074] This invention provides a bioparameter analysis device, comprising: a housing having a window and a door capable of covering the window; a reagent kit capable of being moved into or out of the housing, the reagent kit having a sampling component and a docking component, wherein when the reagent kit is located inside the housing, the sampling component can be rotated out from the window to collect liquid outside the housing; the docking component can dock with the sampling component to enable the sampling component to collect liquid inside the reagent kit; and a linkage component that links the door and the docking component to drive the door to cover the window when the sampling component and the docking component are docked, and to drive the door to open the window when the sampling component and the docking component are separated.

[0075] The bioparameter analysis device provided in this application embodiment, by setting a linkage component between the door on the linkage housing and the docking component on the reagent kit, enables the door to close the window when the sampling component on the reagent kit docks with the docking component to collect the liquid inside the reagent kit, and drives the door to open the window when the sampling component and the docking component separate. At this time, the sampling component can rotate out from the window to collect the liquid outside the reagent kit. By setting the above-mentioned linkage component to link the movement relationship between the docking component and the door, the separate drive mechanism for opening and closing the door can be eliminated, which helps to simplify the overall structure of the device.

[0076] This application provides a sample parameter analysis device, comprising: a housing having a window and a door capable of covering the window; the housing having a first side and a second side disposed opposite to each other, the door being disposed on the first side and rotatably connected to the housing; a connecting assembly disposed on the second side of the housing to connect the housing and the door when the door covers the window; the connecting assembly including a locking member, a driving member, and a first elastic member, one end of the first elastic member being connected to the middle of the locking member and the other end being connected to the housing, one end of the locking member being connected to the driving member and the other end being used to restrict the position of the door when the door covers the window; wherein, the driving member is used to drive the locking member to move to release the restriction on the door, so that the door can rotate relative to the housing and thus open the window, and the first elastic member deforms to generate elastic force when the locking member moves, the elastic force acting on the locking member when the driving member retracts its drive to the locking member, thereby causing the locking member to return to its original position.

[0077] The sample parameter analysis device provided in this application embodiment uses a connecting component to fix the door when it blocks the window, and the connecting component can also release the restriction on the door to allow the door to move and open the window. Specifically, a locking member is used to restrict and fix the door when it closes the window, and a driving member is used to drive the locking member to move and release the restriction on the door. Simultaneously, a first elastic member connects the locking member and the housing, so that when the locking member releases the restriction on the door, it deforms to generate elastic force. This elastic force allows the locking member to return to its original position without requiring the driving member to re-drive it back to its original position, resulting in a simple overall structure.

[0078] This application provides a sample analysis kit, comprising: a base having a first cavity, a second cavity, and an isolator, wherein the isolator is configured to connect or isolate the first cavity and the second cavity, wherein when the first cavity and the second cavity are connected, liquid in the first cavity can flow to the second cavity; wherein the isolator can change its state under the action of an external force to make the first cavity and the second cavity connect, and when the external force is removed, the isolator returns to its state to isolate the first cavity and the second cavity.

[0079] The sample analysis kit provided in this application embodiment isolates the first and second cavities within the housing. When the kit is not in use, the isolation element is changed by external force to connect the first and second cavities, allowing liquid in the first cavity to flow into the second cavity for analysis. Furthermore, when the kit is not in use at the factory, the isolation between the first and second cavities ensures that salt bridges exposed in the second cavity remain dry, thus extending the kit's shelf life.

[0080] This application provides a detection component, including: a first liquid path, a second liquid path, an inlet, an outlet, and a valve assembly; one end of the first liquid path is connected to the inlet, and the other end is connected to the outlet; one end of the second liquid path is connected to the inlet, and the other end is connected to the outlet; the valve assembly is located between the inlet, the outlet, and / or the inlet and the outlet, and can switch between a first conducting state and a second conducting state to control the first liquid path and the second liquid path to be selectively conducting; wherein, in the first conducting state, a first external liquid of the detection component can flow into the first liquid path from the inlet and flow out of the first liquid path from the outlet; in the second conducting state, a second external liquid of the detection component can flow into the second liquid path from the inlet and flow out of the second liquid path from the outlet.

[0081] The detection component provided in this application embodiment controls the selective conduction of a first liquid path and a second liquid path via a valve assembly. When the second liquid path is open, a second external liquid, such as a reference liquid, can enter the second liquid path. When the first liquid path is open, a first external liquid, such as a test sample, can enter the first liquid path. This eliminates the need to pre-fill the detection component with auxiliary measurement liquids such as reference liquids when it is assembled. Instead, the valve assembly controls the conduction of the second liquid path and injects the auxiliary measurement liquids such as reference liquids into it during use. This reduces the volume of the assembled detection component and avoids the problem of the auxiliary measurement liquids such as reference liquids expiring due to the detection component being placed inside and the component not being used for a long time.
