The sample analyzer may be, but is not limited to, a coagulation analyzer, and the coagulation analyzer includes a storage device 10, a reagent needle and a sample needle (the reagent needle and the sample needle are not shown), wherein the storage device 10 includes a mounting rack 11, a cooling member 12 and a carrying rack 13, the mounting rack 11 is used for placing one or more reagent racks 20, the reagent racks 20 are used for placing a plurality of reagent containers 30, and the sizes of the reagent containers 30 placed on the same reagent rack 20 may be the same or different. The reagent needles are used for sucking reagents from the reagent containers 30, the refrigerating part 12 is used for refrigerating the reagent rack 20, the bearing frame 13 is used for placing a sample rack, and the sample needles are used for sucking samples from the sample rack. Wherein, the reagent includes but is not limited to various hemolytic agents, various blood coagulants, displacing agents, inhibitors, diluents, cleaning solutions, etc.; samples include, but are not limited to, blood samples.
In one embodiment, the carrier 13 is arranged alongside the mounting frame 11, which enables a more compact layout of the coagulation analyzer; in other embodiments, the carrier 13 and the mounting bracket 11 may be spaced apart from each other.
The mounting rack 11 comprises a placing surface 111, the placing surface 111 is used for placing the reagent rack 20, in one embodiment, the refrigerating piece 12 is laid on the placing surface 111, and after the reagent rack 20 is placed on the mounting rack 11, the refrigerating piece 12 can refrigerate the reagent rack 20. Specifically, the refrigeration member 12 may be a thin plate, and the thin plate-shaped refrigeration member 12 is directly attached to the placement surface 111. In another embodiment, the placing surface 111 is provided with a concave accommodating hole, and the refrigerating element 12 is filled in the accommodating hole. In a further embodiment, the refrigeration element 12 is embedded inside the mounting frame 11, and the refrigeration element 12 refrigerates from inside the mounting frame 11, in this embodiment, the mounting frame 11 is made of a material with good cold conducting property, such as aluminum, copper, alloy, etc.
It should be noted that, in the present embodiment, the placing surface 111 is inclined with respect to the horizontal plane, that is, the placing surface 111 has a certain slope, and in the use process of the blood coagulation analyzer, both the condensed water generated on the placing surface 111 and the condensed water flowing from the reagent rack 20 to the placing surface 111 can be automatically collected to the lower end along the placing surface 111, and will not be always accumulated on the whole placing surface 111, which will not affect the normal operation of the blood coagulation analyzer, and improves the working efficiency of the blood coagulation analyzer, and the condensed water is collected at the lower end of the placing surface 111, which can facilitate the centralized processing of the condensed water, and can reduce the processing difficulty of the condensed water, and improve the processing efficiency of the condensed water.
The placing surface 111 includes a first end 1111 and a second end 1112 arranged opposite to each other, and when the operator places the reagent rack 20 into the mounting rack 11, the reagent rack 20 is pushed into the mounting rack 11 along the direction from the first end 1111 to the second end 1112.

Of course, in other embodiments, the placing surface 111 may be arranged such that the first end 1111 is lower than the second end 1112, that is, the second end 1112 is inclined to the upper left with respect to the first end 1111 as viewed in fig. 4, so that the condensed water generated during the cooling process is collected at the first end 1111, which is convenient for an operator to handle the collected condensed water.
As shown in fig. 4, an included angle between the placing surface 111 and the horizontal plane is a first angle a, the range of the first angle a is not less than 1 °, for example, 1 °, 3 °, 5 °, 7 °, 10 °, 15 °, 20 °, and the like, the first angle a is only required to ensure that the placing surface 111 can play a role in guiding flow, and the specific angle can be adjusted according to the actual needs of the instrument. In one embodiment, the first angle A is in the range of 1 ° to 5 °, preferably the first angle A is 1 ° to 2 °, e.g., 1 °, 1.2 °, 1.3 °, 1.5 °, 1.7 °, 1.8 °, 2 °, etc. Within this angle range, the placement surface 111 can not only play a role in guiding the blood flow, but also does not affect the overall appearance of the blood coagulation analyzer. In the present embodiment, the first angle a between the placement surface 111 and the horizontal plane is 1.5 °.
As shown in fig. 1 and 2, in order to provide a better diversion effect to the storage apparatus 10 of the present embodiment, a liquid guide groove 112 is provided on a lower side of the mounting surface 111, and in the present embodiment, the liquid guide groove 112 is provided at a second end of the mounting surface 111. It is understood that in other embodiments, the liquid guiding groove 112 is disposed at the first end of the placing surface 111 when the first end of the placing surface 111 is lower than the second end. The liquid guide groove 112 is formed by the placing surface 111 sinking downwards, condensed water can be collected and temporarily stored in the liquid guide groove 112, and the arrangement of the liquid guide groove 112 can prevent the condensed water from flowing to other places along the placing surface 111 again.
The mounting frame 11 further has a second through hole 113 communicating with the liquid guiding groove 112, as shown in fig. 3, the storage device 10 further includes a liquid path assembly 14, and the liquid path assembly 14 is used for guiding out the condensed water. Further, the storage device 10 further includes a header tank 15, and the liquid path assembly 14 is respectively communicated with the second through hole 113 and the header tank 15. The condensed water collected in the liquid guide groove 112 can automatically flow into the liquid collecting tank 15 through the liquid path assembly 14, the liquid collecting tank 15 can contain a large amount of condensed water, the liquid guide groove 112 does not need to be cleaned frequently by operators, and only the liquid collecting tank 15 needs to be cleaned regularly.
Specifically, the liquid path assembly 14 includes a power pump 141, a connecting member 142, a first pipeline 143, and a second pipeline 144, one end of the connecting member 142 is connected to the second through hole 113 in a sealing manner, and specifically, a sealing ring may be disposed between the second through hole 113 and the connecting member 142 to prevent the condensed water from leaking between the wall of the second through hole 113 and the connecting member 142. The other end of the connecting piece 142 is connected with the inlet end of the first pipeline 143, the outlet end of the first pipeline 143 is connected with the inlet of the power pump 141, the outlet of the power pump 141 is connected with the inlet end of the second pipeline 144, and the outlet end of the second pipeline 144 is connected with the header tank 15. The condensed water in the liquid guiding tank 112 can flow through the connecting member 142, the first pipeline 143, the power pump 141, and the second pipeline 144 in sequence, and finally is collected in the liquid collecting tank 15. The liquid path assembly 14 can rapidly suck the condensed water accumulated in the liquid guide groove 112 into the liquid collecting tank 15.
In one embodiment, the connecting member 142 is a connecting joint. In other embodiments, the connector 142 may also be a valve.
The number of the second through holes 113 may be one or more, when the number of the second through holes 113 is more, the plurality of second through holes 113 are arranged at intervals along the length direction of the liquid guide groove 112, a connecting piece 142 is hermetically connected in each second through hole 113, each connecting piece 142 is connected with a branch pipe, the plurality of branch pipes are connected to the first pipeline 143 through a multi-channel joint, and the first pipeline 143 is further communicated with the power pump 141. Therefore, the power pump 141 can communicate with the liquid guiding groove 112 through the second through holes 113 and suck the condensed water in the liquid guiding groove 112, so that the suction efficiency can be improved, and the second through holes 113 can be distributed in different positions in the liquid guiding groove 112 respectively to reduce the accumulated liquid in the liquid guiding groove 112.
In this embodiment, the fluid path assembly 14 further includes a control unit (not shown), which includes a manual control unit or an automatic control unit. In one embodiment, the control unit comprises an automatic control unit, which is a timing unit, and the timing unit is connected to the power pump 141 and is used for controlling the power pump 141 to be turned on or off at regular time so as to clean the condensed water in the liquid guide groove 112 at regular time. In the present embodiment, the timing means is controlled by a software program. It can be understood that, in a short time, the amount of the generated condensed water is not particularly large, and then the amount of the condensed water collected in the liquid guide groove 112 is not particularly large, so that the power pump 141 is not required to be in an on state all the time, and a certain time interval is provided, after enough condensed water is collected in the liquid guide groove 112, the power pump 141 is started again, so that the power pump 141 rapidly pumps and discharges the condensed water collected in the liquid guide groove 112 into the liquid collection tank 15; after one suction and discharge operation is completed, the power pump 141 is turned off again. Therefore, efficient cleaning of the condensate can be guaranteed, and power consumption of the power pump 141 can be saved.
In another embodiment, a liquid level sensor may be used instead of the timing unit, and specifically, the liquid level sensor may be disposed between the liquid guiding tank 112 and the power pump 141, for example, on the first pipeline 143, the liquid level sensor is in signal connection with the power pump 141, when the condensed water detected by the liquid level sensor reaches a preset amount, the power pump 141 is turned on, and after performing a pumping and discharging operation, the power pump 141 is turned off automatically.
In other embodiments, the switch includes a manual switch connected to the power pump 141, which facilitates an operator to manually control the power pump 141 to be turned on or off, and an electronic control element is not required, thereby saving cost. When enough condensed water is stored in the liquid guide tank 112, an operator can start the power pump 141 through the manual switch, and after one suction and discharge action, the power pump 141 is turned off through the manual switch.
Further, the mounting rack 11 further comprises a guide rail 114, and the guide rail 114 is used for guiding the reagent rack 20. When placing reagent frame 20 in the mounting bracket 11, can push reagent frame 20 along guide rail 114 in the mounting bracket 11, not only can avoid reagent frame 20 to put askewly, and reagent frame 20 is placed in the mounting bracket 11 after moreover, and the cooperation structure between guide rail 114 and the reagent frame 20 can be fixed a position reagent frame 20 for reagent frame 20 is more firm, prevents that reagent frame 20 from empting in mounting bracket 11.
In one embodiment, the mounting rack 11 is provided with a plurality of guide rails 114, the plurality of guide rails 114 are arranged on the placing surface 111 side by side, and the plurality of reagent racks 20 can slide into the mounting rack 11 along the plurality of guide rails 114, respectively.
The spacing between different rails 114 and their adjacent rails 114 may be the same or different. Since the storage periods of the reagents in the blood coagulation analyzer are different and the detection amounts of different customers are different, the sizes of the corresponding reagent bottles are different, and correspondingly, the widths (the sizes perpendicular to the extending direction of the guide rail 114) of the reagent racks 20 are different. In order to better satisfy the customer requirements and ensure stable and reliable detection results, for the reagent rack 20 with a large consumption of reagent, the distance between the guide rail 114 and the adjacent guide rail 114 is large, that is, when the adjacent guide rails 114 are used to accommodate reagent racks 20 with different sizes, the distance between the adjacent guide rails 114 is correspondingly set. Obviously, in order to smoothly and stably place the reagent rack 20 at the corresponding position, the spacing between different rails 114 and their adjacent rails 114 is matched to the size of the reagent rack 20 to be placed.
As shown in fig. 4 to 7, the present invention also provides a reagent rack 20, wherein the reagent rack 20 can be well matched with the storage device 10, so that the lowermost ends of the reagent containers 30 are located in the same horizontal plane after the reagent rack 20 is placed on the placing surface 111 of the storage device 10. It is understood that, as shown in fig. 7, if the axial direction of each reagent container 30 is parallel to the vertical direction after the reagent rack 20 is placed on the placement surface 111, the entire bottom surface of each reagent container 30 is located in the same horizontal plane; as shown in fig. 4, when the axial direction of each reagent container 30 is inclined with respect to the vertical direction after the reagent rack 20 is placed on the placement surface 111, the lowermost end of the bottom surface of each reagent container 30 may be located in the same horizontal plane.
Specifically, the reagent rack 20 is provided with a plurality of mounting hole sites 23 for placing the reagent containers 30, when the plurality of reagent containers 30 are respectively accommodated in the plurality of mounting hole sites 23, the bottommost end of each reagent container 30 is located in the working plane 201, the reagent rack 20 includes the contact bottom surface 202, when the contact bottom surface 202 is parallel to the horizontal plane, the working plane 201 is inclined with respect to the horizontal plane, and an included angle between the working plane 201 and the horizontal plane is a first angle, that is, the included angle between the working plane 201 and the horizontal plane is equal to an included angle between the placing plane 111 and the horizontal plane, and an inclined direction of the working plane 201 with respect to the horizontal plane is opposite to an inclined direction of the placing plane 111 with respect to the horizontal plane.
After the reagent rack 20 of the present embodiment is placed on the mounting rack 11, the contact bottom surface 202 is attached to the placing surface 111 or is parallel to the placing surface 111, at this time, the contact bottom surface 202 is inclined with respect to the horizontal plane and forms a first angle with the horizontal plane, and the working plane 201 and the contact bottom surface 202 form a first angle again, so that the working plane 201 is parallel to the horizontal plane, the heights of the lowermost ends of the reagent containers 30 on the reagent rack 20 are the same, and when reagent needles on the blood coagulation analyzer suck reagents from different reagent containers 30, the descending heights of the reagent needles can be kept the same, which can simplify the control procedure of the reagent needles, improve the working efficiency of the blood coagulation analyzer, and reduce the error probability of the blood coagulation analyzer.
The reagent rack 20 comprises a support body 21 and a reagent rack body 22, the mounting holes 23 are formed in the reagent rack body 22, and when the reagent rack 20 is placed on the placing surface 111 through the cooperation of the support body 21 and the reagent rack body 22, the working plane 201 where the bottommost end of the reagent container 30 in each mounting hole 23 is located is parallel to the horizontal plane.
Fig. 4 shows a first embodiment of the reagent rack 20, in which 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 attached to 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. As shown in fig. 4, the placing surface 111 is inclined downward in the X direction, the plurality of mounting holes 23 on the reagent rack 20 are sequentially arranged in the X direction, and the distance between the bottom ends of the plurality of mounting holes 23 and the bottom surface (i.e., the contact bottom surface 202) of the support body 21 increases sequentially in the X direction, so as to offset the influence of the inclined placing surface 111 on the reagent rack 20, and ensure that the working plane 201 where the bottommost end of the reagent container 30 in each mounting hole 23 is located is parallel to the horizontal plane after the reagent rack 20 is placed on the placing surface 111.
Fig. 5 shows a second embodiment of the reagent rack 20, which differs from the first embodiment mainly in 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 for lifting one end of the reagent rack body 22, so that after the reagent rack body 22 is placed on the placing surface 111, the bottommost ends of the reagent containers 30 in the mounting holes 23 are located in the same horizontal plane. In this embodiment, the reagent rack body 22 may be a currently general reagent rack, and only one support body 21 is required to be separately inserted between the general reagent rack and the placing surface 111, so that it is not necessary to additionally design and produce a special reagent rack 20 matched with the placing surface 111, and the production cost can be reduced.
In the working process of the blood coagulation analyzer, the support body 21 can be fixed on the bottom surface of the reagent rack body 22 in a clamping or threaded connection mode, so that the support body 21 can be prevented from shaking randomly in the working process, and the stability of the reagent rack body 22 is ensured; in the non-use state of the reagent rack 20, the support body 21 can be detached from the reagent rack main body 22, facilitating storage of the reagent rack main body 22.
In the second embodiment, the cross section of the support body 21 in the horizontal direction may be the same size 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 understood 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 of the bottom end of the reagent rack body 22 as long as it is ensured that the working plane 201 where the bottom end of each reagent container 30 is located is parallel to the horizontal plane when the reagent rack 20 is placed on the placing surface 111.
Fig. 6 shows a third embodiment of the reagent rack 20, which differs from the first embodiment in that: the supporting body 21 is accommodated in the mounting hole 23, and is used for supporting the reagent containers 30 so that the bottommost 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 a first angle is formed between the working plane 201 and the contact bottom surface 202.
In the third embodiment, the reagent rack body 22 may also be directly used as a current general reagent rack, and only the support bodies 21 need to be adaptively filled in the mounting holes 23 of the general reagent rack, so that the cost is low, and when the inclination angle of the placement surface 111 of the blood coagulation analyzer relative to the horizontal plane is changed, only the support bodies 21 with different heights need to be replaced in the mounting holes 23, so that the flexibility is high.
In the third embodiment, when the mounting surface 111 is inclined downward in the X direction, the plurality of mounting holes 23 on the reagent rack 20 are arranged in order in the X direction, in the X direction, the heights of the supporting bodies 21 in the plurality of mounting holes 23 are sequentially increased, the height of the supporting bodies 21 filled in the mounting holes 23 closer to the lower end of the mounting surface 111 is larger, the height of the supporting bodies 21 filled in the mounting holes 23 farther from the lower end of the mounting surface 111 is smaller (the height of the supporting body 21 filled in the mounting hole 23 farthest from the lower end of the mounting surface 111 may be zero, that is, the supporting body 21 may not be filled in the mounting hole 23 farthest from the lower end of the mounting surface 111), the influence of the inclined mounting surface 111 on the reagent containers 30 is thereby offset, so that the bottom ends of the plurality of reagent containers 30 can be positioned in the same horizontal plane when the plurality of reagent containers 30 are respectively accommodated in the plurality of mounting holes 23.
In the third embodiment, the shape of the supporting body 21 is not limited, and may be adjusted adaptively according to actual needs, as long as the working plane 201 where the bottommost end of each reagent container 30 is located and the contact bottom surface 202 have the first angle after each reagent container 30 is accommodated in the mounting hole.
In the general-purpose reagent rack, when the reagent vessel 30 is set in the mounting hole 23 of the general-purpose reagent rack, the reagent vessel 30 is often in an upright state. In the upright state, when the amount of the reagent remaining in the reagent container 30 is small, it is difficult for the reagent needle to efficiently suck the reagent, so that the dead space in the reagent container 30 is large, resulting in waste of the reagent and increase in cost. In the reagent rack 20 of the present embodiment, the mounting hole 23 is disposed obliquely, and after the reagent container 30 is placed in the mounting hole 23, the reagent container 30 is also in an oblique state, so that even if the amount of the remaining reagent in the reagent container 30 is small, the reagent can be smoothly sucked by the reagent needle, the dead volume of the reagent can be greatly reduced, and the reagent waste can be reduced.
As shown in fig. 4, the side wall of the mounting hole 23 extends along the Y direction, and a second angle B is formed between the Y direction and the vertical direction. The second angle B ranges from 6 deg. -10 deg., such as 6 deg., 7 deg., 8 deg., 8.5 deg., 9 deg., 10 deg., etc. In this angle range, the dead space of the reagent can be minimized, and the volume ratio of the reagent filled in the reagent container 30 to the reagent container 30 can be ensured to be large.
It can be understood that the inclination degrees of the plurality of mounting holes 23 may be the same or slightly different, and on the premise of not affecting reagent suction by the reagent needle, when the plurality of reagent containers 30 are respectively accommodated in the plurality of mounting holes 23, the bottom ends of the plurality of reagent containers 30 are located in the working plane 201.
In the present embodiment, the inclination degrees of the plurality of mounting holes 23 are the same, and the second angles B between the extending directions of the side walls of the plurality of mounting holes 23 and the vertical direction are all 8 °.
Further, an opening 24 is disposed on a side wall of the mounting hole 23, and the opening 24 is communicated with the mounting hole 23, and the opening 24 penetrates through the side wall of the mounting hole 23 and is used for exposing the barcode on the reagent container 30. When the reagent container 30 is accommodated in the mounting hole 23, the bar code on the reagent container 30 corresponds to the opening 24, and the scanning device on the blood coagulation analyzer can scan the bar code on the reagent container 30, so as to record the reagent container 30, thereby facilitating the reagent needle to accurately suck the reagent in the corresponding reagent container 30 in the following working process.
In one embodiment, the bottom wall of the mounting hole 23 is further provided with a first through hole, and during the cooling process, both 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 onto the placing surface 111 through the first through hole, and then flow into the liquid guiding groove 112 along the placing surface 111 to be collected, so as to avoid the condensed water from gathering in the mounting hole 23.
It should be noted that fig. 4-6 all show the reagent rack 20 and the mounting rack 11 in a non-contact state, which is only an illustrative effect in the present invention, and in an actual use state, the reagent rack 20 is in contact with the mounting rack 11.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
