Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] Please refer to Figure 1 The present invention provides a sample analyzer, which can detect samples. The sample analyzer can be, but is not limited to, a coagulation analyzer, which includes a storage device 10, a reagent needle and a sample needle (the reagent needle and the sample needle are not shown in the figure), wherein the storage device 10 includes a mounting frame 11, a refrigeration unit 12 and a carrier frame 13, wherein the mounting frame 11 is used to place one or more reagent racks 20, and the reagent rack 20 is used to place multiple reagent containers 30, and the specifications of the reagent containers 30 placed on the same reagent rack 20 can be the same or different. The reagent needle is used to draw reagents from each reagent container 30, the refrigeration unit 12 is used to cool the reagent rack 20, the carrier frame 13 is used to place the sample rack, and the sample needle is used to draw samples from the sample rack. Among them, the reagents include, but are not limited to, various hemolytic agents, various coagulants, replacement agents, inhibitors, diluents, cleaning solutions, etc.; the samples include, but are not limited to, blood samples.

[0042] In one embodiment, the supporting frame 13 and the mounting frame 11 are arranged side by side, which can make the layout of the coagulation analyzer more compact; in other embodiments, the supporting frame 13 and the mounting frame 11 can also be arranged at a distance.

[0043] The mounting frame 11 includes a placement surface 111, and the placement surface 111 is used to place the reagent rack 20. In one embodiment, the refrigeration element 12 is laid on the placement surface 111. After the reagent rack 20 is placed on the mounting frame 11, the refrigeration element 12 can refrigerate the reagent rack 20. Specifically, the refrigeration element 12 can be a thin plate, and the thin plate-shaped refrigeration element 12 is directly attached to the placement surface 111. In another embodiment, a recessed accommodating hole is provided on the placement surface 111, and the refrigeration element 12 is filled in the accommodating hole. In another embodiment, the refrigeration element 12 is embedded in the inside of the mounting frame 11, and the refrigeration element 12 is refrigerated from the inside of the mounting frame 11. In this embodiment, the mounting frame 11 is made of a material with better cold conduction performance, such as aluminum, copper, alloy, etc.

[0044] It should be particularly noted that the placement surface 111 of the present embodiment is inclined relative to the horizontal plane, that is, the placement surface 111 has a certain slope. During the use of the coagulation analyzer, the condensed water generated on the placement surface 111 and the condensed water flowing from the reagent rack 20 to the placement surface 111 can automatically gather to the lower end along the placement surface 111, and will not be accumulated on the entire placement surface 111, which will not affect the normal operation of the coagulation analyzer and improve the working efficiency of the coagulation analyzer. Moreover, the collection of condensed water at the lower end of the placement surface 111 can facilitate its centralized treatment, which can reduce the difficulty of treating the condensed water and improve the treatment efficiency of the condensed water.

[0045] The placement surface 111 includes a first end 1111 and a second end 1112 that are arranged opposite to each other. When the operator places the reagent rack 20 into the mounting frame 11, the reagent rack 20 is pushed into the mounting frame 11 along the direction from the first end 1111 to the second end 1112. In this embodiment, the first end 1111 is higher than the second end 1112. Figure 4 The viewing angle is shown. The second end 1112 is tilted toward the lower left relative to the first end 1111. When the operator pushes the reagent rack 20 into the mounting frame 11, it is pushed from the higher end of the placement surface 111 to the lower end. The operation is relatively labor-saving. Moreover, since the inner end of the placement surface 111 (i.e., the second end 1112) is lower than the outer end (i.e., the first end 1111), the reagent rack 20 is not easy to slide after being placed on the placement surface 111. The condensed water generated during the refrigeration process will gather at the second end 1112, which can prevent the operator standing near the first end 1111 from touching the gathered condensed water. Of course, in other embodiments, the placement surface 111 can also be set so that the first end 1111 is lower than the second end 1112. Figure 4 As shown is the observation angle, the second end 1112 is inclined toward the upper left relative to the first end 1111, and the condensed water generated during the refrigeration process will be collected at the first end 1111, which can facilitate the operator to handle the collected condensed water.

[0046] like Figure 4 As shown, the angle between the placement surface 111 and the horizontal plane is a first angle A, and the range of the first angle A is not less than 1°, for example, 1°, 3°, 5°, 7°, 10°, 15°, 20°, etc. The first angle A can be adjusted according to the actual needs of the instrument as long as it can ensure that the placement surface 111 can play a diversion role. In one embodiment, the range of the first angle A is 1°-5°, and preferably, the first angle A is 1°-2°, for example, 1°, 1.2°, 1.3°, 1.5°, 1.7°, 1.8°, 2°, etc. Within this angle range, the placement surface 111 can play a diversion role without affecting the overall appearance of the coagulation analyzer. In this embodiment, the first angle A between the placement surface 111 and the horizontal plane is 1.5°.

[0047] like Figure 1 and Figure 2As shown, in order to make the storage device 10 of this embodiment have a better diversion effect, a liquid guide groove 112 is provided on the lower side of the placement surface 111. In this embodiment, the liquid guide groove 112 is provided at the second end of the placement surface 111. It can be understood that in other embodiments, when the first end of the placement surface 111 is lower than the second end, the liquid guide groove 112 is provided at the first end of the placement surface 111. The liquid guide groove 112 is formed by the placement surface 111 being concave downward, and the condensed water can be collected and temporarily stored in the liquid guide groove 112. The provision of the liquid guide groove 112 can prevent the condensed water from flowing to other places along the placement surface 111.

[0048] The mounting frame 11 is also provided with a second through hole 113 communicating with the liquid guiding groove 112. Figure 3 As shown, the storage device 10 further includes a liquid circuit assembly 14, which is used to guide the condensed water out. Further, the storage device 10 further includes a liquid collecting box 15, and the liquid circuit assembly 14 is connected to the second through hole 113 and the liquid collecting box 15 respectively. The condensed water collected in the liquid guiding groove 112 can automatically flow into the liquid collecting box 15 through the liquid circuit assembly 14. The liquid collecting box 15 can hold a large amount of condensed water, and the operator does not need to frequently clean the liquid guiding groove 112, but only needs to clean the liquid collecting box 15 regularly.

[0049] Specifically, the liquid circuit assembly 14 includes a power pump 141, a connector 142, a first pipeline 143 and a second pipeline 144. One end of the connector 142 is sealed and connected to the second through hole 113. Specifically, a sealing ring can be provided between the second through hole 113 and the connector 142 to prevent condensed water from leaking from the hole wall of the second through hole 113 and the connector 142. The other end of the connector 142 is connected to the inlet end of the first pipeline 143, the outlet end of the first pipeline 143 is connected to the inlet of the power pump 141, the outlet of the power pump 141 is connected to the inlet end of the second pipeline 144, and the outlet end of the second pipeline 144 is connected to the liquid collecting tank 15. The condensed water in the liquid guiding groove 112 can flow through the connector 142, the first pipeline 143, the power pump 141, and the second pipeline 144 in sequence, and finally collect in the liquid collecting tank 15. The liquid circuit assembly 14 can quickly draw the condensed water collected in the liquid guiding groove 112 into the liquid collecting tank 15 .

[0050] In one embodiment, the connecting member 142 is a connecting joint. In other embodiments, the connecting member 142 can also be a valve.

[0051] The number of the second through holes 113 can be one or more. When the number of the second through holes 113 is more than one, the multiple second through holes 113 are arranged at intervals along the length direction of the liquid-conducting groove 112. A connector 142 is sealed and connected in each second through hole 113. Each connector 142 is connected to a branch pipe. The multiple branch pipes are connected to the first pipeline 143 through a multi-channel joint. The first pipeline 143 is then connected to the power pump 141. In this way, the power pump 141 can be connected to the liquid-conducting groove 112 through the multiple second through holes 113 and suck the condensed water in the liquid-conducting groove 112, which can not only improve the suction efficiency, but also the multiple second through holes 113 are respectively distributed at different positions in the liquid-conducting groove 112 to reduce the accumulation of liquid in the liquid-conducting groove 112.

[0052] In this embodiment, the liquid circuit assembly 14 also includes a control unit (not shown in the figure), and the control unit includes a manual control unit or an automatic control unit. In one embodiment, the control unit includes an automatic control unit, and the automatic control unit is a timing unit, which is connected to the power pump 141 and is used to control the power pump 141 to be turned on or off at a fixed time, so as to clean the condensed water in the liquid guide groove 112 at a fixed time. In this embodiment, the timing unit is controlled by a software program. It can be understood that in a short period of time, the amount of condensed water generated will not be particularly large, so the amount of condensed water collected in the liquid guide groove 112 will not be particularly large. Therefore, there is no need to keep the power pump 141 in the turned-on state all the time. After a certain period of time, when enough condensed water is collected in the liquid guide groove 112, the power pump 141 can be turned on again, so that the power pump 141 can quickly suck and discharge the condensed water collected in the liquid guide groove 112 into the liquid collection box 15; after one suction and discharge action is completed, the power pump 141 is turned off again. In this way, the efficient cleaning of the condensed liquid can be guaranteed, and the power consumption of the power pump 141 can be saved.

[0053] In another embodiment, a liquid level sensor can be used instead of the timing unit. Specifically, the liquid level sensor can be set between the liquid guiding groove 112 and the power pump 141, for example, on the first pipeline 143. The liquid level sensor is connected to the power pump 141 signal. When the condensed water detected by the liquid level sensor reaches a preset amount, the power pump 141 is turned on, and after a suction and discharge action, the power pump 141 is automatically turned off.

[0054] In other embodiments, the switch includes a manual switch, which is connected to the power pump 141, so that the operator can manually control the power pump 141 to start or shut down, without the need to set up electronic control components, which can save costs. When enough condensed water is stored in the liquid guide groove 112, the operator can start the power pump 141 through the manual switch, perform a suction and discharge action, and then shut down the power pump 141 through the manual switch.

[0055] Furthermore, the mounting frame 11 further includes a guide rail 114, which is used to guide the reagent rack 20. When the operator places the reagent rack 20 in the mounting frame 11, the reagent rack 20 can be pushed into the mounting frame 11 along the guide rail 114, which can not only prevent the reagent rack 20 from being placed crooked, but also after the reagent rack 20 is placed in the mounting frame 11, the matching structure between the guide rail 114 and the reagent rack 20 can position the reagent rack 20, making the reagent rack 20 more stable and preventing the reagent rack 20 from tipping over in the mounting frame 11.

[0056] In one embodiment, a plurality of guide rails 114 are disposed on the mounting frame 11 . The plurality of guide rails 114 are arranged side by side on the placement surface 111 . The plurality of reagent racks 20 can slide into the mounting frame 11 along the plurality of guide rails 114 , respectively.

[0057] The intervals between different guide rails 114 and their adjacent guide rails 114 can be the same or different. Due to the different storage periods of reagents in the coagulation analyzer, and the detection amounts of different customers are different, the sizes of the corresponding reagent bottles are different, and accordingly, the widths (dimensions perpendicular to the extension direction of the guide rails 114) of the reagent rack 20 are different. In order to better meet customer needs and ensure that the test results are stable and reliable, for the reagent rack 20 with large consumption of reagents, the distance between its guide rails 114 and the adjacent guide rails 114 is relatively large, that is, when the adjacent guide rails 114 are used to accommodate the reagent racks 20 with different sizes, the spacings of the adjacent guide rails 114 are correspondingly set. Obviously, in order to place the reagent rack 20 smoothly and stably in the corresponding position, the spacings between the different guide rails 114 and the adjacent guide rails 114 are matched with the size of the reagent rack 20 to be placed.

[0058] like Figures 4 to 7 As shown, the present invention further provides a reagent rack 20, which can be well matched with the storage device 10, so that after the reagent rack 20 is placed on the placement surface 111 of the storage device 10, the bottom ends of the reagent containers 30 are located in the same horizontal plane. It can be understood that, as Figure 7 As shown, if the reagent rack 20 is placed on the placement surface 111, the axial direction of each reagent container 30 is parallel to the vertical direction, and the entire bottom surface of each reagent container 30 is located in the same horizontal plane; Figure 4 As shown, if the reagent rack 20 is placed on the placement surface 111 and the axial direction of each reagent container 30 is inclined relative to the vertical direction, it is sufficient for the lowest ends of the bottom surfaces of each reagent container 30 to be located in the same horizontal plane.

[0059] Specifically, the reagent rack 20 is provided with a plurality of mounting holes 23 for placing reagent containers 30. When the plurality of reagent containers 30 are respectively accommodated in the plurality of mounting holes 23, the bottom end of each reagent container 30 is located in the working plane 201. The reagent rack 20 includes a contact bottom surface 202. When the contact bottom surface 202 is parallel to the horizontal plane, the working plane 201 is inclined relative to the horizontal plane, and the angle between the working plane 201 and the horizontal plane is a first angle, that is, the angle between the working plane 201 and the horizontal plane is equal to the angle between the placement surface 111 and the horizontal plane, and the inclination direction of the working plane 201 relative to the horizontal plane is opposite to the inclination direction of the placement surface 111 relative to the horizontal plane.

[0060] After the reagent rack 20 of this embodiment is placed on the mounting frame 11, the contact bottom surface 202 is in contact with the placement surface 111 or is parallel to the placement surface 111. At this time, the contact bottom surface 202 is inclined relative to the horizontal plane and forms a first angle with the horizontal plane, while the working plane 201 and the contact bottom surface 202 form a first angle, so that the working plane 201 is parallel to the horizontal plane, and the bottom ends of the reagent containers 30 on the reagent rack 20 are at the same height. When the reagent needle on the coagulation analyzer draws reagents from different reagent containers 30, the height to which the reagent needle descends can remain consistent. This can simplify the control program of the reagent needle, improve the working efficiency of the coagulation analyzer, and reduce the error probability of the coagulation analyzer.

[0061] The reagent rack 20 includes a support body 21 and a reagent rack body 22, and mounting holes 23 are provided on the reagent rack body 22. The support body 21 and the reagent rack body 22 cooperate to ensure that when the reagent rack 20 is placed on the placement surface 111, the working plane 201 at the bottom end of the reagent container 30 in each mounting hole 23 is parallel to the horizontal plane.

[0062] Figure 4 The first specific embodiment of the reagent rack 20 is shown. In the first specific embodiment, the support body 21 is located at the bottom end of the reagent rack body 22, the top surface of the support body 21 is in contact with the bottom surface of the reagent rack body 22, and the contact bottom surface 202 is located at the bottom end of the support body 21. The support body 21 and the reagent rack body 22 are integrally formed, that is, there is no obvious dividing line between the support body 21 and the reagent rack body 22. Figure 4 As shown, the placement surface 111 is tilted downward along the X direction, and the multiple installation holes 23 on the reagent rack 20 are arranged in sequence along the X direction. In the X direction, the distances between the bottom ends of the multiple installation holes 23 and the bottom surface of the support body 21 (that is, the contact bottom surface 202) are increased in sequence, thereby offsetting the influence of the tilted placement surface 111 on the reagent rack 20, ensuring that after the reagent rack 20 is placed on the placement surface 111, the working plane 201 where the bottom ends of the reagent containers 30 in each installation hole 23 are located is parallel to the horizontal plane.

[0063] Figure 5 The second specific embodiment of the reagent rack 20 is shown. The main difference between the second specific embodiment and the first specific embodiment is that the support body 21 and the reagent rack body 22 are separately arranged, and the support body 21 is detachably connected to the bottom end of the reagent rack body 22, and is used to lift one end of the reagent rack body 22, so that after the reagent rack body 22 is placed on the placement surface 111, the bottom ends of the reagent containers 30 in each installation hole 23 are located in the same horizontal plane. In this embodiment, the reagent rack body 22 can directly adopt the current common reagent rack, and a single support body 21 can be placed between the common reagent rack and the placement surface 111, without the need to design and produce a special reagent rack 20 that matches the placement surface 111, which can reduce production costs.

[0064] During the operation of the coagulation analyzer, the support body 21 can be fixed to the bottom surface of the reagent rack body 22 by means of snap connection or threaded connection, so as to avoid any shaking of the support body 21 during the operation and ensure the stability of the reagent rack body 22; when the reagent rack 20 is not in use, the support body 21 can be removed from the reagent rack body 22 to facilitate the storage of the reagent rack body 22.

[0065] In the second specific embodiment, the size of the cross section of the support body 21 in the horizontal direction may be the same as the bottom surface of the reagent rack body 22, or may be smaller than the bottom surface of the reagent rack body 22. It is understandable that when the cross section of the support body 21 in the horizontal direction is smaller than the bottom surface of the reagent rack body 22, the support body 21 may be disposed at any position at the bottom end of the reagent rack body 22, as long as it can be ensured that when the reagent rack 20 is placed on the placement surface 111, the working plane 201 where the bottom end of each reagent container 30 is located is parallel to the horizontal plane.

[0066] Figure 6 The third specific embodiment of the reagent rack 20 is shown. The difference between the third specific embodiment and the first specific embodiment is that the support body 21 is accommodated in the installation hole 23 and is used to support the reagent containers 30 so that the bottom end of each reagent container 30 is located in the working plane 201, the contact bottom surface 202 is located at the bottom end of the reagent rack body 22, and there is a first angle between the working plane 201 and the contact bottom surface 202.

[0067] In the third specific embodiment, the reagent rack body 22 can also directly adopt the currently common reagent rack. It only needs to adaptively fill the support body 21 in the installation hole 23 of the common reagent rack, which is low in cost. When the inclination angle of the placement surface 111 of the coagulation analyzer relative to the horizontal plane changes, it is only necessary to replace the support body 21 of different heights in each installation hole 23, which is highly flexible.

[0068] In the third specific embodiment, when the placement surface 111 is tilted downward along the X direction, the multiple mounting holes 23 on the reagent rack 20 are arranged sequentially along the X direction. In the X direction, the heights of the support bodies 21 in the multiple mounting holes 23 increase sequentially. The height dimension of the support body 21 filled in the mounting holes 23 closer to the lower end of the placement surface 111 is larger, and the height dimension of the support body 21 filled in the mounting holes 23 farther away from the lower end of the placement surface 111 is smaller (the height dimension of the support body 21 filled in the mounting holes 23 farthest from the lower end of the placement surface 111 can be zero, that is, the support body 21 can be placed in the mounting holes 23 farthest from the lower end of the placement surface 111). In this way, the influence of the tilted placement surface 111 on the reagent container 30 is offset, so that when the multiple reagent containers 30 are respectively accommodated in the multiple mounting holes 23, the bottom ends of the multiple reagent containers 30 can still be in the same horizontal plane.

[0069] In the third specific embodiment, the shape of the support body 21 is not limited and can be adaptively adjusted according to actual needs, as long as it is ensured that after each reagent container 30 is accommodated in the installation hole, there is a first angle between the working plane 201 where the bottom end of each reagent container 30 is located and the contact bottom surface 202.

[0070] In a common reagent rack, when the reagent container 30 is placed in the mounting hole 23 of the common reagent rack, the reagent container 30 is mostly in an upright state. In the upright state, when the amount of reagent remaining in the reagent container 30 is small, it is difficult for the reagent needle to effectively absorb the reagent, so that the dead space in the reagent container 30 is large, resulting in reagent waste and rising costs. In the reagent rack 20 of the present embodiment, the mounting hole 23 is tilted, and after the reagent container 30 is placed in the mounting hole 23, the reagent container 30 is also in an inclined state, and even if the amount of reagent remaining in the reagent container 30 is small, the reagent needle can also smoothly absorb the reagent, which can greatly reduce the dead space of the reagent and reduce the waste of the reagent.

[0071] like Figure 4 As shown, the side wall of the mounting hole 23 extends along the Y direction, and a second angle B is provided between the Y direction and the vertical direction. The second angle B ranges from 6° to 10°, for example, 6°, 7°, 8°, 8.5°, 9°, 10°, etc. Within this angle range, the dead space of the reagent can be minimized, and the volume ratio of the reagent container 30 to the reagent container 30 can be ensured to be large.

[0072] It is understandable that the inclination degrees of the multiple mounting holes 23 can be the same or slightly different, without affecting the reagent needle to absorb the reagent, and ensuring that when the multiple reagent containers 30 are respectively accommodated in the multiple mounting holes 23, the bottom ends of the multiple reagent containers 30 are located in the working plane 201.

[0073] In this embodiment, the inclination degrees of the plurality of mounting holes 23 are the same, and the second angles B between the extension directions of the side walls of the plurality of mounting holes 23 and the vertical direction are all 8°.

[0074] Furthermore, an opening 24 is provided on the side wall of the mounting hole 23, and the opening 24 is connected to the mounting hole 23. The opening 24 penetrates the side wall of the mounting hole 23 and is used to expose the barcode on the reagent container 30. When the reagent container 30 is accommodated in the mounting hole 23, the barcode on the reagent container 30 can correspond to the opening 24, and the scanning device on the coagulation analyzer can scan the barcode on the reagent container 30, and then record the reagent container 30, so that the reagent needle can accurately absorb the reagent in the corresponding reagent container 30 in the subsequent working process.

[0075] In one embodiment, a first through hole is further provided on the bottom wall of the mounting hole 23. During the refrigeration process, the condensed water generated on the reagent container 30 and the condensed water generated on the inner wall of the mounting hole 23 can flow to the placement surface 111 through the first through hole, and then flow along the placement surface 111 to the liquid guide groove 112 for collection, thereby preventing the condensed water from gathering in the mounting hole 23.

[0076] It should be noted that Figure 4-Figure 6 The states shown are all those in which the reagent rack 20 and the mounting rack 11 are not in contact, which is only for illustration in the present invention. In actual use, the reagent rack 20 and the mounting rack 11 are in contact.

Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
