The phrase appears at various places in the specification does not necessarily all refer to the same embodiments, nor is it necessarily independent or alternative embodiments to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] The present application provides a sample analysis device 100, please refer to Figures 1 to 3 , wherein Figure 1 is a structural schematic diagram of the sample analysis device provided by the present application in a first state, Figure 2 is Figure 1 a structural schematic diagram of the sample analysis device shown in the second state.

[0045] The sample analysis device 100 is used to detect the collected sample to obtain an analysis report, so as to facilitate medical staff to judge whether the biological index of the sample is normal and assist medical staff to understand the disease condition.

[0046] The sample analysis device 100 includes a host 10 and a refrigeration assembly 20 movably arranged on the host 10, wherein the refrigeration assembly 20 is used to store reagents that need to be refrigerated. For example, latex reagents for CRP (C-reactive protein, C-reactive protein) or SAA (Serum amyloid A, serum amyloid A) detection, calibration solution or cleaning solution and other reagents that need to be refrigerated.

[0047] In the present embodiment, the refrigeration assembly 20 is slidingly arranged on the host 10, which can slide relative to the host 10 to be accommodated in the host 10 or extend out of the host 10.

[0048] Optionally, the refrigeration assembly 20 can also be hinged to the main machine 10, so that it can rotate relative to the main machine 10, rotate towards the main machine 10 to be accommodated in the main machine 10, or rotate away from the main machine 10 to extend out of the main machine 10.

[0049] The refrigeration assembly 20 can be arranged on the right side, the left side, the front, or the back of the main machine 10, wherein the direction is defined as the scenario in which the user faces the sample loading position of the sample analysis device 100 as the reference. As shown in Figure 1 and Figure 2 In the present embodiment, the refrigeration assembly 20 is arranged on the right side of the main machine 10.

[0050] As shown in Figure 1 and Figure 2 The refrigeration assembly 20 has two states relative to the main machine 10, namely a first state and a second state. In the first state, the refrigeration assembly 20 is in a closed state relative to the main machine 10, and the sample analysis device 100 can also perform sample detection. In the second state, the refrigeration assembly 20 is in an open state relative to the main machine 10, and the user can replace reagents.

[0051] As shown in Figure 2 The sample analysis device 100 is in the second state, and the refrigeration assembly 20 extends out of the main machine 10, which can facilitate the user to replace or supplement reagents that need to be refrigerated. As shown in Figure 1 The sample analysis device 100 is in the first state, and the refrigeration assembly 20 is accommodated in the main machine 10. The reagents stored therein are in a state that can be picked up, so that the reagent dispensing assembly in the main machine 10 can obtain the reagents and add them to the reaction pool.

[0052] Referring to Figure 3 , Figure 3 is Figure 1 a cross-sectional structural schematic diagram of the refrigeration assembly in the sample analysis device. The refrigeration assembly 20 includes a reagent refrigeration chamber 21 and a refrigeration module 22. The refrigeration module 22 is connected with the refrigeration chamber 21 and is used to supply cold to the reagent refrigeration chamber 21.

[0053] In combination with reference to Figures 1 to 3 In the first state, the reagent refrigeration chamber 21 and the refrigeration module 22 are both accommodated in the main machine 10. In the second state, the reagent refrigeration chamber 21 and the refrigeration module 22 are both extended out of the main machine 10. In other words, the positions of the reagent refrigeration chamber 21 and the refrigeration module 22 are relatively fixed, for example, the reagent refrigeration chamber 21 and the refrigeration module 22 can be directly fixedly connected, or fixedly connected through auxiliary materials such as a fixing frame, so that the reagent refrigeration chamber 21 and the refrigeration module 22 are simultaneously changed between the first state and the second state, that is, the refrigeration module 22 also follows the reagent refrigeration chamber 21 to be extended out of the main machine 10.

[0054] The reagent refrigeration chamber 21 can store multiple reagents of the same type or different types at the same time, and the amount of each reagent can be different. When part of the reagents need to be replaced because they are consumed, part of the reagents are not consumed, and therefore, when the reagents are replaced, the reagent refrigeration chamber 21 needs to continue to be cooled.

[0055] The reagent refrigeration chamber 21 can store multiple reagents of the same type or different types at the same time, and the amount of each reagent can be different. When part of the reagents need to be replaced because they are consumed, part of the reagents are not consumed, and therefore, when the reagents are replaced, the reagent refrigeration chamber 21 needs to continue to be cooled.

[0056] In the first state and the second state, the refrigeration module 22 keeps cooling the reagent refrigeration chamber 21, avoiding the risk of excessive temperature rise of the reagent refrigeration chamber 21 due to being outside the main machine 10.

[0057] Alternatively, in the second state, the refrigeration module 22 can be temporarily suspended to continue to cool the reagent refrigeration chamber 21 with the cold energy generated by itself. Since the time required for replacing reagents and the like is relatively short, even if the refrigeration module 22 is temporarily suspended, the cold energy remaining in the refrigeration module 22 is sufficient to cool the reagent refrigeration chamber 21, so that the temperature of the reagent refrigeration chamber 21 rises relatively little during the replacement of the reagents, and the quality of the refrigerated reagents is almost not affected.

[0058] Further, the sample analysis device 100 further comprises a heat dissipation assembly 30, which is used to accelerate heat dissipation of the refrigeration module 22.

[0059] Alternatively, the heat dissipation assembly 30 is connected with the refrigeration assembly 20, so that in the second state, the heat dissipation assembly 30 and the refrigeration assembly 20 are extended out of the main machine 10 at the same time.

[0060] Alternatively, the heat dissipation assembly 30 is fixedly arranged in the main machine 10, so that in the second state, the heat dissipation assembly 30 is located in the main machine 10 and does not extend out of the main machine 10 with the refrigeration assembly 20.

[0061] The heat dissipation assembly 30 can include a heat dissipation fan and / or a heat dissipation fin.

[0062] Alternatively, as shown in Figure 3 The heat dissipation assembly 30 and the refrigeration assembly 20 are fixedly connected, and the heat dissipation assembly 30 moves with the refrigeration assembly 20, and the heat dissipation assembly 30 can dissipate heat for the refrigeration module 22 in the first state and the second state.

[0063] Optionally, the heat dissipation assembly 30 is fixed in the main machine 10, and in the first state, the heat dissipation assembly 30 accelerates the heat dissipation of the refrigeration module 22, and in the second state, the heat dissipation assembly 30 is spaced from the refrigeration module 22. For example, the heat dissipation assembly 30 is a heat dissipation fan, and in the second state, the heat dissipation assembly 30 can be temporarily stopped, and then the heat dissipation assembly 30 resumes work after the refrigeration assembly 20 is returned to the main machine 10; or the heat dissipation assembly 30 can keep working in the first state and the second state.

[0064] Referring to Figures 4 to 6 , Figure 4 is a schematic view of the cooperation structure of the refrigeration assembly and the locking assembly in the sample analysis device shown in Figure 1 is a schematic view of the refrigeration assembly and the locking assembly shown in Figure 5 is a schematic view of the refrigeration assembly shown in Figure 4 Figure 6 Figure 4

[0065] The reagent refrigeration chamber 21 comprises a bin body 211 and a cover body 212, the bin body 211 has an opening, and the cover body 212 is connected with the bin body 211 and is arranged at the opening in correspondence, and the cover body 212 cooperates with the bin body 211 to open or close the opening.

[0066] In the first state, the reagent refrigeration chamber 21 is accommodated in the main machine 10, and the cover body 212 covers the bin body 211, i.e. the opening is closed. The cover body 212 is movably arranged on the bin body 211, and in the second state, the cover body 212 is extended out of the main machine 10 together with the bin body 211; or the cover body 212 is fixedly arranged in the main machine 10, in the first state, the cover body 212 cooperates with the bin body 211 to close the opening, and in the second state, the cover body 212 is located in the main machine 10 and does not extend out of the main machine 10 together with the bin body 211, and in this state, the opening is in an open state.

[0067] Optionally, the cover body 212 is hingedly connected with the bin body 211, and in the second state, the cover body 212 can be opened to expose the reagent stored in the bin body 211, and after the reagent is replaced or supplemented, the cover body 212 is arranged on the bin body 211, and then the refrigeration assembly 20 is pushed back into the main machine 10. Alternatively, the cover body 212 and the bin body 211 can be slidably connected.

[0068] Optionally, the cover body 212 is detachably connected with the bin body 211, i.e. the cover body 212 can be completely separated from the bin body 211. In the first state, the cover body 212 covers the bin body 211 to close the opening of the bin body 211; and in the second state, the cover body 212 uncovers the bin body 211 to open the opening of the bin body 211.

[0069] ​​​Specifically, the cover 212 is fixedly arranged in the main machine 10, and during the process of sliding the refrigeration assembly 20 from the main machine 10 to outside of the main machine 10, the cover 212 is gradually separated from the bin body 211, so as to unseal the bin body 211, thereby omitting the step of manually opening the cover of the reagent refrigeration chamber 21 by the user, and enabling the opening operation of the reagent refrigeration chamber 21 to be completed at the same time of pulling out the refrigeration assembly 20, thereby making the reagent replacement more convenient.

[0070] For example, one of the bin body 211 and the cover 212 is provided with a sliding groove, and the other is provided with a sliding rail, the sliding rail and the sliding groove are in sliding cooperation, and the cover 212 can seal the bin body 211; or in the first state, the cover 212 is pressed on the bin body 211 to seal the opening of the bin body 211, and when the refrigeration assembly 20 needs to be pulled out to the outside of the main machine 10, the pressing force on the cover 212 is removed to release the fixed relationship, so that the bin body 211 can slide relative to the cover 212.

[0071] The bin body 211 is provided with at least one reagent placement position (not shown), and the cover 212 is arranged above the reagent placement position. The reagent placement position corresponds to a reagent container (not shown). The cover 212 is provided with a suction port 213, and the suction port 213 is arranged corresponding to the bottle opening of the reagent container.

[0072] The bin body 211 can be provided with one or more reagent placement positions. Each reagent placement position can correspond to a reagent container, and each reagent container can load the same type of reagent, or multiple reagent containers can load multiple types of reagents.

[0073] Optionally, the bin body 211 is provided with at least two reagent placement positions, and the reagent containers corresponding to the at least two reagent placement positions load at least two types of reagents. For example, the bin body 211 is provided with two reagent placement positions, and the corresponding two reagent containers load different types of reagents, i.e. two types of reagents, for example, the two different types of reagents can be CRP detection reagent and SAA detection reagent, or one can be CRP detection reagent or SAA detection reagent, and the other can be quality control or calibration standard; or the bin body 211 is provided with three reagent placement positions, and the corresponding three reagent containers can load two or three different types of reagents. If there are two different types of reagents, one reagent container loads one type of reagent, and the other two reagent containers load the same type of another type of reagent. If there are three different types of reagents, the three reagent containers load different types of reagents respectively.

[0074] For reference Figures 4 to 7 , wherein Figure 7 is Figure 4 the structure diagram of the locking assembly shown in FIG. 8.

[0075] The sample analysis device 100 further comprises a locking assembly 40 arranged in the main machine 10. The refrigeration assembly 20 is slidingly arranged on the bearing wall of the main machine 10, so that the refrigeration assembly 20 can have a closed state and an open state relative to the main machine 10, i.e. a first state and a second state; the locking assembly 40 is arranged on the bearing wall of the main machine 10, and cooperates with the refrigeration assembly 20 to lock or unlock the refrigeration assembly 20.

[0076] Specifically, the locking assembly 40 can change the refrigeration assembly 20 from the locked state to the unlocked state, and also can change the refrigeration assembly 20 from the unlocked state to the locked state.

[0077] In the unlocked state, the refrigeration assembly 20 can move relative to the main machine 10 to change from the first state to the second state, or change from the second state to the first state; in the locked state, the refrigeration assembly 20 cannot slide relative to the main machine 10 and is in the first state.

[0078] In this embodiment, the refrigeration assembly 20 is slidingly arranged on the bearing wall of the main machine 10 in the first direction, and the refrigeration assembly 20 is further provided with a first limiting piece 24. The reagent refrigeration chamber 21 is used to store reagents that need to be refrigerated.

[0079] The locking assembly 40 comprises a locking piece 42, which can be extended and retracted in a second direction, and the locking piece 42 cooperates with the first limiting piece 24 to lock or unlock the refrigeration assembly 20. The second direction can be perpendicular to the first direction, or can be arranged at an angle to the first direction.

[0080] In this embodiment, the second direction is perpendicular to the first direction.

[0081] The locking piece 42 extends outward to insert into the first limiting piece 24, thereby locking the refrigeration assembly 20; the locking piece 42 retracts inward to disengage from the first limiting piece 24, thereby unlocking the refrigeration assembly 20.

[0082] In this embodiment, the locking piece 42 is a shaft structure, and the first limiting piece 24 is provided with a limiting hole or a limiting slot, and the locking piece 42 is inserted into the limiting hole or the limiting slot, so as to limit the cooperation with the first limiting piece 24 to lock the refrigeration assembly 20; the locking piece 42 disengages from the limiting hole or the limiting slot, so as to unlock the refrigeration assembly 20.

[0083] Alternatively, the locking piece 42 can also be a rod structure.

[0084] The application sets the refrigeration assembly 20 to be arranged in sliding along the first direction, and is provided with a locking assembly 40 for locking or unlocking the refrigeration assembly 20, wherein the locking piece 42 extends outward to be inserted into the first limiting piece 24, thereby being capable of locking the refrigeration assembly 20; the locking piece 42 is retracted inward to be separated from the first limiting piece 24, thereby being capable of unlocking the refrigeration assembly 20, and after the refrigeration assembly 20 is unlocked, it can slide out along the first direction, so as to replace the reagent stored therein, thereby making the refrigeration mechanism open more conveniently and facilitating the replacement of the reagent.

[0085] The locking piece 42 can be manually driven, for example, the user manually controls the locking piece 42 to extend or retract.

[0086] In the embodiment, as shown in Figure 4 and Figure 6 , the locking assembly 40 further comprises a power piece 44 for driving the locking piece 42 to move, the power piece 44 can be used for driving the locking piece 42 to retract inward, and the power piece 44 can also be used for driving the locking piece 42 to extend outward.

[0087] Optionally, the power piece 44 is an electric motor or an air cylinder, which is connected with the locking piece 42 and is used for driving the locking piece 42 to extend or retract.

[0088] Specifically, the power piece 44 is an electromagnet, and when the power piece 44 is powered on, the electromagnet magnetically attracts the locking piece 42 to drive the locking piece 42 to retract inward, thereby unlocking the first limiting piece 24.

[0089] The locking assembly 40 further comprises a resilient piece 45, which is elastically compressed between the power piece 44 and the stop portion of the locking piece 42, and when the power piece 44 is powered off, the resilient piece 45 drives the locking piece 42 to extend outward.

[0090] Specifically, when the power piece 44 is powered on, the electromagnet has a magnetic attraction force, the locking piece 42 is made of ferromagnetic material at least towards one end of the power piece 44, the electromagnet magnetically attracts the locking piece, so that the locking piece 42 moves towards the electromagnet to retract inward and compresses the resilient piece 45, thereby unlocking the first limiting piece 24; when the power piece 44 is powered off, the electromagnet loses the magnetic attraction force, and the resilient piece 45 rebounds to drive the locking piece 42 to extend outward.

[0091] The resilient piece 45 can be a compression spring or an elastic sleeve.

[0092] By setting the power piece 44 as an electromagnet to drive the locking piece 42 to retract inward, and setting the resilient piece 45 between the power piece 44 and the locking piece 42 to drive the locking piece 42 to extend outward, compared with the scheme of using an electric motor or an air cylinder, the scheme adopted in the embodiment has obvious advantages in cost, is low in cost, and can be extremely small in size, occupies small space, and is convenient to install in the main machine 10.

[0093] Specifically, as shown in Figure 5 The first limiting member 24 has a guide slope 241 and a limiting groove 242, and during the process that the refrigeration assembly 20 is transformed from the second state to the first state, the locking member 42 is inserted into the limiting groove 242 along the guide slope 241.

[0094] Further, as shown in Figure 6 The locking assembly 40 further includes a position detector 46 and a support block 47, the locking member 42 is arranged through the support block 47, and the position detector 46 is arranged on the support block 47 and used for detecting whether the locking member 42 is connected with the first limiting member 24.

[0095] The position detector 46 adopts a trigger of a push piece, which cooperates with the first limiting member 24, when the locking member 42 is connected with the first limiting member 24, the push piece on the position detector 46 is also triggered by the first limiting member 24, so that it can be confirmed that the refrigeration assembly 20 is locked.

[0096] Further, as shown in Figure 3 and Figure 5 The sample analysis device 100 further includes a switch member 51, which is electrically connected with the power member 44 and used for controlling the start and stop of the power member 44. After the switch member 51 is triggered, the power member 44 can be powered for a set time, for example, 2 seconds or 3 seconds, so that the locking member 42 contacts the locking of the first limiting member 24, and after the set time, the power member 44 is powered off.

[0097] The switch member 51 can be a physical button switch, which can be arranged on the side panel of the refrigeration assembly 20, that is, the side panel of the reagent refrigeration chamber 21 exposed outside the host 10, and a handle 52 can also be arranged on the side panel, so as to facilitate the user to hold the handle 52 to push and pull the refrigeration assembly 20.

[0098] Alternatively, the switch member 51 can also be integrated on the handle 52 and hidden by the handle 52, so that when the user drags the refrigeration assembly 20 through the handle 52, the switch member 51 can be triggered, so that the switch key 31 is triggered to release the locking of the refrigeration assembly 20, and the refrigeration assembly 20 is dragged to transform from the first state to the second state, and the two actions are combined into one action, that is, the action of dragging the refrigeration assembly 20 through the handle 52, which greatly optimizes and simplifies the operation procedure of opening the sample analysis device 100, and makes it more convenient to replace the reagent of the sample analysis device 100.

[0099] For example, the switch key 31 is a photoelectric switch, which is arranged behind the handle 52 and is blocked by the handle 52, and when the user drags the handle 52, the user's fingers can trigger the switch member 51 after blocking the photoelectric switch.

[0100] For example, the switch member 51 is a knob on the handle 52, and the user can press the trigger switch member 51 when pulling the handle 52.

[0101] The handle 52 can be arranged horizontally or vertically to facilitate the user to hold the handle 52.

[0102] Alternatively, the switch member 51 can also be arranged on the main machine 10.

[0103] In other embodiments, the start and stop of the power member 44 can also be controlled by a program, and a corresponding control icon is arranged on the program interface to trigger the start and stop of the power member 44 by clicking the mouse or touching the icon with the user's finger.

[0104] Referring to Figure 4 The reagent refrigeration chamber 21 is further provided with a first tension member 53 on the side away from the handle 52, and the sample analysis device 100 further comprises a second tension member (not shown). When the locking member 42 locks the refrigeration assembly 20, the second tension member further cooperates with the first tension member 53 to fix the refrigeration assembly 20 and prevent the refrigeration assembly 20 from shaking.

[0105] The locking member 42 cooperates with the first limiting member 24, and when the locking member 42 locks the first limiting member 24, there is a slight gap between the locking member 42 and the first limiting member 24, so that the refrigeration assembly 20 can shake. As a whole, if the refrigeration assembly 20 can still shake in the closed state, it will greatly affect the quality of the sample analysis device 100, such as affecting the sampling of reagents, or affecting the appearance of the sample analysis device 100. By arranging the second tension member and the first tension member 53, the refrigeration assembly 20 can be further fixed after the locking member 42 locks the refrigeration assembly 20 to prevent the refrigeration assembly 20 from shaking.

[0106] The first tension member 53 and the second tension member can be one of a magnet and a ferromagnetic member, and can be fixed by magnetic attraction to prevent the refrigeration assembly 20 from shaking.

[0107] The first tension member 53 and the second tension member can also be two structural members that are buckled to each other.

[0108] The refrigeration assembly 20 has a first limiting position and a second limiting position on the movement trajectory in the first direction. When the refrigeration assembly 20 is in the first limiting position, it is accommodated in the main machine 10, i.e. the sample analysis device 100 is in the first state, and the locking member 42 is used to limit the refrigeration assembly 20 to be located at the first limiting position. When the refrigeration assembly 20 is in the second limiting position, the refrigeration assembly 20 extends out of the main machine 10, i.e. the sample analysis device 100 is in the second state. During the movement of the refrigeration assembly 20 from the first limiting position to the second limiting position, the sample analysis device 100 changes from the first state to the second state.

[0109] AsFigures 3 to 5 As shown, the refrigeration assembly 20 is further provided with a second limiting member 25. The sample analysis device 100 further comprises a positioning member (not shown) arranged on the bearing wall of the main machine 10, and the positioning member is used to cooperate with the second limiting member 25 to limit the refrigeration assembly 20 at the second limiting position.

[0110] When the refrigeration assembly 20 is at the first limiting position, the locking member 42 extends outward to lock the first limiting member 24; when the refrigeration assembly 20 is at the second limiting position, the positioning member cooperates with the second limiting member 25 to limit the refrigeration assembly 20 at the second limiting position.

[0111] In the embodiment, the second limiting member 25 is a ferromagnetic block, and the positioning member is a magnet. The positioning member magnetically attracts the second limiting member 25, so that the user can obtain obvious feedback when pulling the refrigeration assembly 20 to the second limiting position, and the refrigeration assembly 20 can be stably limited at the second limiting position. At the same time, it is also convenient for the user to push the refrigeration assembly 20 back, so that the refrigeration assembly 20 returns to the first limiting position.

[0112] Alternatively, the second limiting member 25 can also be a marble, and the positioning member is a structural member provided with a groove. When the marble is clamped in the groove on the positioning member, the refrigeration assembly 20 is at the second limiting position.

[0113] Further, as shown in Figure 4 The refrigeration assembly 20 is further provided with a third limiting member 26, and the sample analysis device 100 further comprises a stop member (not shown) used to block the third limiting member 26 to prevent the refrigeration assembly 20 from being overloaded and disengaged from the slide rail, that is, to prevent the refrigeration assembly 20 from disengaging from the main machine 10.

[0114] The movement track of the refrigeration assembly 20 further has a stop position, which is arranged near the second limiting position and between the first limiting position and the stop position. When the refrigeration assembly 20 is at the stop position, the third limiting member 26 is blocked by the stop member, and the positioning member can still magnetically attract the second limiting member 25, so that the refrigeration assembly 20 returns to the second limiting position to limit the refrigeration assembly 20 at the second limiting position in the open state, and avoid the refrigeration assembly 20 from freely sliding uncontrollably in the open state.

[0115] The third limiting member 26 can be a protrusion, and the stop member can be a stop block or a protruding column, etc., which can block the third limiting member 26.

[0116] Referring to Figure 8 , Figure 8 is a top view structural schematic diagram of an embodiment of the cascade sample analysis system provided by the present application.

[0117] Based on this, the application further provides a cascade sample analysis system 200, which comprises a first sample analysis device 201 and a second sample analysis device 202, and at least one of the first sample analysis device 201 and the second sample analysis device 202 is the sample analysis device 100 as described above.

[0118] For example, the cascade sample analysis system 200 comprises the first sample analysis device 201 and the second sample analysis device 202 arranged side by side, and the front side of the first sample analysis device 201 and the second sample analysis device 202 is further provided with a sample feeding rail 203 for conveying detection samples to the first sample analysis device 201 and the second sample analysis device 202, wherein the first sample analysis device 201 has a CRP detection module or a SAA detection module, and the first sample analysis device 201 is provided with the refrigeration assembly 20 for storing and providing latex reagents, and the second sample analysis device 202 is a blood cell analyzer, the first sample analysis device 201 is located at the right side of the second sample analysis device 202, and the refrigeration assembly 20 can be arranged at the right side of the first sample analysis device 201, where the right side is the right side of the user when the user faces the instrument, so that the refrigeration assembly 20 is arranged at the right side to facilitate the user with right-handed habit to replace the latex reagent; the refrigeration assembly 20 can also be arranged at the front side of the first sample analysis device 201, so that the space layout between the instruments of the entire cascade sample analysis system 200 can be more compact, and the user can also conveniently replace the latex reagent at the front side of the instrument. Alternatively, the first sample analysis device 201 and the second sample analysis device 202 both have a CRP detection module or a SAA detection module, and the first sample analysis device 201 and the second sample analysis device 202 are both provided with the refrigeration assembly 20 for storing and providing reagents.

[0119] The cascade sample analysis system 200 comprises the first sample analysis device 201 and the second sample analysis device 202, and it can be understood that the cascade sample analysis system 200 comprises at least two sample analysis devices, and at least one of the sample analysis devices is the sample analysis device 100 as described above.

[0120] The cascade sample analysis system 200 can further comprise a third sample analysis device, which can be the sample analysis device 100 as described above or a sample analysis device without the refrigeration assembly 20.

[0121] The plurality of sample analysis devices comprised by the cascade sample analysis system 200 can be arranged side by side or in an L shape, and the application does not make specific limitations in this regard.

[0122] In practical applications, for example, three sample analysis devices are arranged in a row, the three sample analysis devices detect different items, and a reagent needs to be refrigerated in one of the sample analysis devices. In this case, the sample analysis device 100 described above is used, and the remaining sample analysis devices can be non-refrigerated sample analysis devices.

[0123] Different from the prior art, the application discloses a sample analysis device and a cascaded sample analysis system. The refrigeration module and the reagent refrigeration chamber can be extended out of the main machine together, so that the reagent refrigeration chamber can supply cold to the refrigeration module when the reagent is replaced or loaded, and the temperature change of the reagent refrigeration chamber during replacement of the reagent is avoided, so that the adverse effects on the reagents stored in the reagent refrigeration chamber and the reagents replaced are avoided. That is, the sample analysis device provided by the application can provide a good refrigeration environment for the reagents throughout the process, and the risk of failure of the reagents due to temperature change is reduced.

[0124] The above is only an embodiment of the application, and does not limit the patent scope of the application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the application.
