Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an opening and closing door structure and a sample analyzer. Background Art

[0002] When performing high-speed sample analysis, sample analyzers often require reagents to perform the corresponding tests. Reagents are typically contained in reagent containers, which are stored in a reagent container storage mechanism. To achieve high-speed, non-stop sample analysis during the sample analysis process, online reagent replenishment is often performed through online loading to address the issue of continuous reagent depletion.

[0003] Since reagents often need to be stored under certain temperature conditions, the reagent container storage mechanism usually has a heat preservation function. During the online loading process of reagents, it is necessary to open / close the reagent compartment door so that the temperature environment in the reagent container storage mechanism can be restored as soon as possible after the online loading of reagents is completed.

[0004] Existing reagent compartment doors are often driven by setting up a separate driving device, resulting in a more complex structure and higher cost of the sample analyzer. In addition, during the online loading of reagent containers, the reagent compartment door is opened to a fully open state in advance and closed later each time, resulting in a large exchange flux and a long exchange time between the temperature inside the reagent container storage mechanism and the external ambient temperature. This is not only not conducive to controlling the temperature of the internal environment of the reagent container storage mechanism and affecting the refrigeration efficiency, but also easily causes the reagent container storage mechanism and the reagent containers stored in the reagent container storage mechanism to generate condensed water, affecting the use of reagents. Summary of the Invention

[0005] The main purpose of this application is to provide an opening and closing door structure and a sample analyzer to solve the problem in the prior art that the reagent compartment door is driven by a separate driving device, and the internal temperature of the reagent container storage mechanism is exchanged with the external ambient temperature to generate condensed water.

[0006] According to one aspect of the present application, there is provided an opening and closing door structure, comprising:

[0007] A follower door, which is openably and closably provided on the compartment cover of the reagent container storage mechanism;

[0008] The reagent container transfer mechanism has an initial position and a working position. The follower door can follow the reagent container transfer mechanism. When the reagent container transfer mechanism is in the initial position, the follower door is closed on the compartment cover. When the reagent container transfer mechanism is in the working position, the follower door is opened on the compartment cover. The reagent container transfer mechanism can place the reagent container in the reagent container storage mechanism or transfer the reagent container in the reagent container storage mechanism.

[0009] Furthermore, the reagent container transfer mechanism drives the follower door to move and gradually open during the movement from the initial position to the working position, and the reagent container transfer mechanism drives the follower door to move and gradually close during the movement from the working position to the initial position.

[0010] Furthermore, it further comprises a push handle, which is provided on the follower door or on the reagent container transfer mechanism;

[0011] The reagent container transfer mechanism includes a pick-up and placement device, a horizontal drive device and a lifting drive device, wherein the pick-up and placement device is horizontally moved by the horizontal drive device and is lifted and lowered by the lifting drive device;

[0012] When the reagent container transfer mechanism switches from the initial position to the working position, the pusher drives the follower door to gradually open.

[0013] Furthermore, the follower door is connected to the compartment cover via a guide assembly, and the guiding direction of the guide assembly is the same as the driving direction of the horizontal driving device;

[0014] The lifting drive device is provided at the output end of the horizontal drive device, and the picking and placing device is provided at the output end of the lifting drive device;

[0015] During the process of the reagent container transfer mechanism switching from the initial position to the working position, the horizontal drive device drives the lifting drive device and the pick-and-place device to move horizontally synchronously, and the lifting drive device is in contact with the push handle and drives the follow-up door to gradually open through the push handle.

[0016] Furthermore, the reagent container storage mechanism includes at least a rotatable first carrying tray and a second carrying tray, wherein the first carrying tray is arranged on the inner side of the second carrying tray, and the first carrying tray is structured to form a plurality of first carrying positions, and the second carrying tray is structured to form a plurality of second carrying positions, and each of the first carrying positions and each of the second carrying positions can respectively carry a reagent container;

[0017] The working position includes at least a first sub-working position and a second sub-working position. When the reagent container transfer mechanism is in the first sub-working position, the follower door is opened on the compartment cover with a first opening area, and the reagent container transfer mechanism can place the reagent container in a first carrying position or transfer the reagent container in the first carrying position. When the reagent container transfer mechanism is in the second sub-working position, the follower door is opened on the compartment cover with a second opening area, and the reagent container transfer mechanism can place the reagent container in a second carrying position or transfer the reagent container in the second carrying position, wherein the second opening area is smaller than the first opening area.

[0018] Furthermore, the follower door is rotatably connected to the compartment cover;

[0019] The push handle is provided on the follow-up door, and the horizontal driving device drives the lifting driving device and the picking and placing device to move synchronously toward the follow-up door, and drives the follow-up door to rotate through the push handle to open the follow-up door.

[0020] Furthermore, the follower door is provided with a first magnetic member, and the reagent container transfer mechanism is provided with a second magnetic member that repel the first magnetic member;

[0021] When the reagent container transfer mechanism is in the initial position, the repulsive force between the first magnetic member and the second magnetic member is insufficient to drive the follower door to open, and the follower door is closed on the compartment cover. When the reagent container transfer mechanism is in the working position, under the mutual repulsion between the first magnetic member and the second magnetic member, the follower door opens on the compartment cover, and the reagent container transfer mechanism can place the reagent container in the reagent container storage mechanism, or transfer the reagent container in the reagent container storage mechanism away.

[0022] Furthermore, a telescopic rod is connected between the follow-up door and the reagent container transfer mechanism;

[0023] When the reagent container transfer mechanism is in the initial position, the telescopic rod is in the maximum extension state so that the follow-up door is closed on the compartment cover. When the reagent container transfer mechanism is in the working position, the telescopic rod is in the retracted state, and the follow-up door is opened on the compartment cover. The reagent container transfer mechanism can place the reagent container in the reagent container storage mechanism or transfer the reagent container in the reagent container storage mechanism.

[0024] Furthermore, a reset member is provided between the follower door and the bin cover, and the reset member is used to drive the follower door to close on the bin cover.

[0025] On the other hand, the present application also provides a sample analyzer, which includes an opening and closing door mechanism as described above, and also includes a reagent container cache tray, and the reagent container transfer mechanism can be used to transfer reagent containers between the reagent container cache tray and the reagent container storage mechanism.

[0026] In the present application, the reagent compartment door used for online loading of reagent containers is set as a follower door, and the follower door is driven to open synchronously by the reagent container transfer mechanism, thereby avoiding the need to set up a dedicated reagent compartment door driving device, thereby effectively controlling production costs. At the same time, by setting up the follower door, the opening time and opening area of ​​the follower door during the online loading of reagent containers can be effectively shortened, thereby effectively shortening the exchange time and exchange amount per unit time between the internal ambient temperature of the reagent container storage mechanism and the external ambient temperature, thereby facilitating the control of the internal temperature of the reagent container storage mechanism to reduce the impact of temperature changes on the reagent containers, and effectively reducing the risk of condensation water generation in the reagent container storage mechanism and the reagent containers stored inside the reagent container storage mechanism, thereby reducing the impact of condensation water on the reagent container storage mechanism and the reagents stored in the reagent containers.

DETAILED DESCRIPTION

[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0040] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0041] See Figure 1-4 As shown, the present application provides an opening and closing door structure, which includes a follower door 10 that is openably and closably provided on a compartment cover 21 of a reagent container storage mechanism 20, and a reagent container transfer mechanism. When the reagent container transfer mechanism transfers a target reagent container 100 into or out of the reagent container storage mechanism 20, the follower door 10 will follow the movement of the reagent container transfer mechanism to open or close on the compartment cover 21.

[0042] Furthermore, the reagent container transfer mechanism has an initial position and an operating position. When the reagent container transfer mechanism is in the initial position, the follower door 10 is closed on the compartment cover 21. At this point, the interior of the reagent container storage mechanism 20 is isolated from the external environment and is sealed, thereby effectively preventing convection of air with a temperature difference between the external and internal environments, thereby ensuring that the reagent containers 100 carried in the reagent container storage mechanism 20 are within a preset temperature range.

[0043] When the reagent container transfer mechanism is in the working position, the follower door 10 is opened on the compartment cover 21 , and the reagent container transfer mechanism can place the reagent container 100 in the reagent container storage mechanism 20 or transfer the reagent container 100 in the reagent container storage mechanism 20 away.

[0044] In the present application, the follower door 10 can follow the reagent container transfer mechanism to open or close, so that the follower door 10 can be opened or closed on the compartment cover 21 without setting up a dedicated driving device for driving; and thereby the overall structure of the opening and closing door structure is simplified, thereby reasonably reducing the cost of the opening and closing door structure.

[0045] At the same time, compared with the prior art in which a dedicated driving device is provided to drive the reagent compartment door to open in advance and close with a delay, the present application can also effectively shorten the time for the follower door 10 to be opened during the transfer of the target reagent container 100, thereby effectively shortening the time for air convection to occur between the inside of the reagent container storage mechanism 20 and the outside world, thereby reducing the impact of air convection with temperature difference on the reagents contained in the reagent container 100 carried in the reagent container storage mechanism 20, and reducing the risk of condensation water generated by air convection, thereby avoiding the impact of condensation water on the reagent container storage mechanism 20 and the reagents contained in the reagent container 100 carried by it.

[0046] In addition, when transferring the target reagent container 100, the existing reagent compartment door needs to be driven by the dedicated driving device and opened to the maximum opening state, resulting in a large amount of air convection flux between the interior of the reagent container storage mechanism 20 and the external environment per unit time. The follower door 10 of the present application follows the reagent container transfer mechanism to prevent the follower door 10 from opening to the maximum opening state. Therefore, the follower door 10 of the present application can effectively control the opening area of ​​the follower door 10, thereby reducing the air convection flux per unit time, thereby reducing the impact of air convection on the reagents contained in the reagent containers 100 carried in the reagent container storage mechanism 20, and further reducing the risk of condensation due to air convection, thereby preventing the impact of condensation on the reagent container storage mechanism 20 and the reagents contained in the reagent containers 100 carried therein.

[0047] Furthermore, when the reagent container transfer mechanism moves from the working position to the initial position, the follower door 10 follows the movement of the reagent container transfer mechanism and gradually closes, so as to avoid delayed closing of the follower door 10 .

[0048] In the first embodiment, the opening and closing door structure further includes a push handle 40 , and the push handle 40 is provided on the follower door 10 or on the reagent container transfer mechanism.

[0049] When the reagent container transfer mechanism switches from the initial position to the working position, the pusher 40 is used to push the follower door 10 to open on the compartment cover 21 along with the reagent container transfer mechanism.

[0050] During the process of the reagent container transfer mechanism switching from the working position to the initial position, the pusher 40 is used to restrict the follower door 10 from gradually closing on the compartment cover 21 along with the reagent container transfer mechanism.

[0051] Preferably, a buffer 34 is further provided on the reagent container transfer mechanism, and the buffer 34 is used to prevent the reagent container transfer mechanism and the pusher 40 from colliding and causing wear when the reagent container transfer mechanism drives the follow-up door 10 to follow; or prevent the pusher 40 from colliding and causing wear with the follow-up door 10.

[0052] Furthermore, a reset member 60 is provided between the follow-up door 10 and the compartment cover 21 , and the reset member 60 is used to drive the follow-up door 10 to remain closed on the compartment cover 21 .

[0053] In one embodiment, the push handle 40 is provided on the follower door 10. When the reagent container transfer mechanism gradually opens the follower door 10 via the push handle 40, the reset member 60 is subjected to the force of the follower door 10 and gradually accumulates force. After the reagent container transfer mechanism completes the transfer of the target reagent container 100, the reagent container transfer mechanism moves from the working position to the initial position. At this point, the reset member 60 gradually releases the accumulated force to drive the follower door 10 and the reagent container transfer mechanism to follow each other until the follower door 10 closes on the compartment cover 21.

[0054] It should be noted that the reset member 60 may be an elastic element, such as a spring, a metal spring, a silicone member, etc. During the movement of the reagent container transfer mechanism from the initial position to the working position, the elastic element is gradually compressed to store force.

[0055] The reset member 60 may also be a mutually repelling magnetic component, such as the reset member 60 includes a first magnetic member and a second magnetic member that repel each other, the first magnetic member is provided on the follow-up door 10, and the second magnetic member is provided on the compartment cover 21 and corresponds to the position of the first magnetic member; or the reset member 60 may also be a third magnetic member and a fourth magnetic member that attract each other, the third magnetic member is provided on the follow-up door 10, and the fourth magnetic member is provided on the reagent container transfer mechanism.

[0056] Furthermore, the reagent container transfer mechanism includes a pick-up and placement device 31, a horizontal drive device, and a lifting drive device. The pick-up and placement device 31 is moved horizontally by the horizontal drive device, so that the pick-up and placement device 31 can transfer the target reagent container 100 in the horizontal direction. The pick-up and placement device 31 can also be moved up and down by the lifting drive device, so that the pick-up and placement device 31 can move in the vertical direction to pick up or place the target reagent container 100.

[0057] In one embodiment, the horizontal drive device is provided at the output end of the lifting drive device, so that the lifting drive device can drive the horizontal drive device to move up and down in the vertical direction. The pick-and-place device 31 is provided at the output end of the horizontal drive device, so that the horizontal drive device can drive the pick-and-place device 31 to move in the horizontal direction.

[0058] In another embodiment, the lifting drive device is provided at the output end of the horizontal drive device, so that the horizontal drive device can drive the lifting drive device to move in the horizontal direction. The pick-and-place device 31 is provided at the output end of the lifting drive device, so that the lifting drive device can drive the pick-and-place device 31 to move in the vertical direction.

[0059] Therefore, during the process of the reagent container transfer mechanism switching from the initial position to the working position, the horizontal drive device drives the lifting drive device and the picking and placing device 31 to move horizontally synchronously, and the lifting drive device is in contact with the push handle 40 and drives the follow-up door 10 to gradually open through the push handle 40.

[0060] Furthermore, the pick-up and placement device 31 is used to pick up and place the target reagent container 100, and to transfer and hold the target reagent container 100 during the picking and placement. For example, when the reagent container 100 is in the initial position, the lifting drive device drives the pick-up and placement device 31 to move downward in the vertical direction until the pick-up and placement device 31 picks up the target reagent container 100 to be loaded into the reagent container storage mechanism 20; then, the lifting drive device drives the pick-up and placement device 31 that has picked up the target reagent container 100 to move upward in the vertical direction to the initial position; then, the horizontal drive device drives the lifting drive device and the pick-up and placement device 31 that has picked up the target reagent container 100 to move horizontally to the initial position. working position, during which the follow-up door 10 follows and opens; then, the lifting drive device drives the picking and placing device 31 to move downward in the vertical direction again until the target reagent container 100 passes through the compartment cover 21 to be placed in the reagent container storage mechanism 20; then, the lifting drive device drives the picking and placing device 31 to move in the vertical direction to the working position again; then, the horizontal drive device drives the lifting drive device and the picking and placing device 31 from the working position to the initial position, during which the follow-up door 10 follows and closes.

[0061] Furthermore, the pick-and-place device 31 may be a clamp, and the clamp is used to clamp the target reagent container 100. The clamp may be an electric clamp, a pneumatic clamp, or an electromagnetic clamp.

[0062] Alternatively, the taking and placing device 31 may be a vacuum suction member, which can suck or release the target reagent container 100. The vacuum suction member may be a vacuum suction cup.

[0063] Furthermore, the lifting drive device is installed on a first mounting frame 35, and the first mounting frame 35 is installed on a bracket 36. The bracket 36 is provided with a yield area 361, and a reagent container cache tray 70 can be set below the yield area 361. The reagent container cache tray 70 is used to cache reagent containers 100. The reagent container 100 can be a reagent container 100 to be loaded into the reagent container storage mechanism 20, or a reagent container 100 transferred out of the reagent container storage mechanism 20.

[0064] Furthermore, the reagent container cache tray 70 is rotatable and has a plurality of placement positions, each of which can accommodate one reagent container 100 .

[0065] When the reagent container transfer mechanism is in the initial position, the lifting drive device can drive the pick-up and placement device 31 to move in the vertical direction and pass through the clearance area 361 to pick up the target reagent container 100 from the reagent container cache tray 70, or place a reagent container 100 on one of the placement positions.

[0066] Furthermore, in one embodiment, the lifting drive device includes a first motor 331, a first screw rod, and a first nut. The first motor 331 is mounted on the first mounting frame 35, the first screw rod is arranged in the vertical direction, and one end of the first screw rod is connected to the output end of the first motor 331.

[0068] In other embodiments, the lifting drive device includes a first motor 331, a first gear, and a first rack. The first motor 331 is mounted on the first mounting bracket 35. The first gear is rotatably mounted at the output end of the first motor 331. The first rack is vertically connected to the pick-and-place device 31, and the first gear meshes with the first rack. The first motor 331 drives the first gear to move forward and reverse, thereby moving the first rack vertically, thereby driving the pick-and-place device 31 to move upward and downward.

[0069] Preferably, a first guide assembly is further provided on the first mounting frame 35 in the vertical direction. The first guide assembly is connected to the pick-and-place device 31 and is used to cooperate with the lifting drive device to drive the pick-and-place device 31 to move more stably in the vertical direction.

[0070] Furthermore, the first guide assembly may be a first guide rail 371 and a first slide, wherein the first slide is connected to the pick-and-place device 31 and is slidably connected to the first guide rail 371. Alternatively, the first guide assembly may be a first guide rod and a first guide sleeve, wherein the first guide sleeve is connected to the pick-and-place device 31 and is slidably sleeved on the first guide rod.

[0071] Furthermore, the horizontal driving device is installed on the second mounting frame 38, the second mounting frame 38 is installed on the bracket 36, and the lifting drive is installed at the output end of the horizontal driving device.

[0072] Furthermore, in one embodiment, the horizontal drive device includes a second motor, a second screw rod, and a second nut.

The second nut changes its position on the second screw rod as the second screw rod rotates, thereby driving the pick-up and placement device 31 to move in the horizontal direction.

[0073] In another embodiment, the horizontal drive device includes a second motor, a second driving wheel, a second driven wheel, and a second belt. The second motor is mounted on the second mounting frame 38, the second driving wheel is rotatably mounted on the output end of the second motor, the second driven wheel is rotatably mounted on the second mounting frame 38 and is located directly below the second driving wheel in the horizontal direction, the second belt is disposed between the second driving wheel and the second driven wheel and can be transmitted between the second driving wheel and the second driven wheel under the drive of the second motor.

[0075] Preferably, a second guide assembly is further provided on the second mounting frame 38 along the horizontal direction. The second guide assembly is connected to the pick-and-place device 31 and is used to cooperate with the horizontal driving device to drive the pick-and-place device 31 to move more stably along the horizontal direction.

[0077] In a second embodiment, a first magnetic element is provided on the movable door 10, and a second magnetic element is provided on the reagent container transfer mechanism that repel the first magnetic element. The opening of the movable door 10 can be controlled by utilizing the mutual repulsive force between the first and second magnetic elements, as well as by controlling the distance between the first and second magnetic elements. Compared to the push handle 40 described in the first embodiment, this embodiment avoids direct contact between the reagent container transfer mechanism and the movable door 10, thereby preventing collisions from affecting the accuracy of the movable door 10 and the reagent container transfer mechanism, as well as preventing wear caused by collisions.

[0078] Furthermore, when the reagent container transfer mechanism is in the initial position, the repulsive force between the first magnetic member and the second magnetic member is insufficient to drive the follower door 10 to open, and the follower door 10 is closed on the compartment cover 21 under the action of the reset member 60 .

[0079] When the reagent container transfer mechanism is in the working position, the first magnetic member and the second magnetic member repel each other, causing the follower door 10 to overcome the force of the reset member 60 and open onto the compartment cover 21. At this point, the reagent container transfer mechanism can place a target reagent container 100 into the reagent container storage mechanism 20 or remove a target reagent container 100 from the reagent container storage mechanism 20.

[0080] In the third embodiment, a telescopic rod is connected between the movable door 10 and the reagent container transfer mechanism, and the telescopic rod can be extended and retracted correspondingly with the movement of the reagent container transfer mechanism, so that the movable door 10 can be opened or closed accordingly.

[0081] Furthermore, when the reagent container transfer mechanism is in the initial position, the telescopic rod is in the maximum extension state, so that the follower door 10 is closed on the compartment cover 21. In this embodiment, by utilizing the extension of the telescopic rod to drive the follower door 10 to close, the use of the reset member 60 to reset the follower door 10 can be avoided, thereby simplifying the overall structure of the opening and closing door structure.

[0082] When the reagent container transfer mechanism is in the working position, the telescopic rod is in a retracted state. At this time, the follower door 10 is opened on the compartment cover 21, and the reagent container transfer mechanism can place the target reagent container 100 in the reagent container storage mechanism 20, or transfer the target reagent container 100 in the reagent container storage mechanism 20 away.

[0083] See also Figure 5As shown, in one embodiment, the reagent container storage mechanism 20 includes a rotatable single-circle carrier plate, on which a plurality of carrier positions are formed, wherein each carrier position can carry one reagent container 100 .

[0084] See also Figure 6 As shown, in another embodiment, the reagent container storage mechanism 20 includes at least a rotatable first carrier tray 22 and a second carrier tray 23. The first carrier tray 22 is disposed inside the second carrier tray 23, and the first carrier tray 22 is configured to have a plurality of first carrier positions 221, each of which can carry a reagent container 100. The second carrier tray 23 is configured to have a plurality of second carrier positions 231, each of which can also carry a reagent container 100.

[0085] Furthermore, the working position includes at least a first sub-working position and a second sub-working position. When the reagent container transfer mechanism is in the first sub-working position, the follower door 10 is opened on the compartment cover 21 with a first opening area. At this time, the reagent container transfer mechanism can place the reagent container 100 in one of the first loading positions 221 or transfer the reagent container 100 in the first loading position 221.

[0086] When the reagent container transfer mechanism is in the second sub-working position, the follower door 10 is opened on the compartment cover 21 with a second opening area. At this time, the reagent container transfer mechanism can place the reagent container 100 in one of the second loading positions 231 or transfer the reagent container 100 in the second loading position 231 away.

[0087] Furthermore, the second opening area is smaller than the first opening area. Thus, the follower door 10 can be opened adaptively according to the placement position of the target actual container, thereby preventing the follower door 10 from opening too large, which would lead to an unnecessary increase in the air convection flow between the interior of the reagent container storage mechanism 20 and the outside world per unit time. This is beneficial for controlling the temperature within the reagent container storage mechanism 20 and reducing condensation caused by air convection with temperature differences within the reagent container storage mechanism 20 and the reagent containers 100 carried therein.

[0088] Furthermore, in one embodiment, the first carrying plate 22 and the second carrying plate 23 can rotate independently of each other.

[0095] In some embodiments, the slider 53 and the follower door 10 are an integrated structure.

[0096] In the second embodiment, the guide assembly includes a slide rail and a slide seat. The slide rail is provided on the compartment cover 21 , and the slide seat is slidably provided on the slide rail and connected to the follower door 10 .

[0097] In a third embodiment, the guide assembly may also be a T-slot or a dovetail slot, and the follower door 10 is disposed in the T-slot or the dovetail slot along the horizontal movement direction.

[0098] Furthermore, in one embodiment, the follow-up door 10 is made of a heat-insulating material, so that the follow-up door 10 has a better heat-insulating effect.

[0099] In another embodiment, a heat insulating layer may be provided on the inner side and / or outer side of the movable door 10, thereby providing the movable door 10 with a better heat insulating and heat retaining effect. For example, a layer mounting groove may be constructed on the inner side of the movable door 10, and the heat insulating layer may be provided in the mounting groove.

[0100] Please refer to Figure 1-4As shown, the compartment cover 21 is further provided with a manual compartment door 24 , and the manual compartment door 24 can be used to manually replace the reagent container 100 .

[0101] Furthermore, the manual door 24 can be hingedly connected to the compartment cover 21 by means of a hinge 25 or the like, and a torsion spring can be provided to prevent the manual door 24 from closing automatically when in the open state; alternatively, an opening angle greater than 90 degrees can be provided to prevent the manual door 24 from closing automatically when in the open state.

[0102] Furthermore, the manual door 24 and the compartment cover 21 may be closed by magnetic attraction, or the manual door 24 may be locked and closed on the compartment cover 21 by means of a buckle or a snap.

[0103] Furthermore, a hand position 241 is provided on the manual door 24 , and the setting of the hand position 241 makes it convenient for the operator to open or close the manual door 24 .

[0106] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0107] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0108] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
