It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0038] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0039] The present application embodiment provides a sample analyzer. Figure 1 , including a sample supply mechanism 1, a reagent loading disk 2, a sample dispensing mechanism 3, a reagent dispensing mechanism 4 and a detection device.

[0040] The sample supply mechanism 1 is used to carry a sample container containing a sample to be measured. The sample supply mechanism 1 can be a sample tray, which includes a plurality of sample positions such as sample tubes. The sample tray can dispatch the sample to a corresponding position by rotating its tray structure, for example, a position for the sample dispensing mechanism 3 to absorb the sample. Of course, the sample supply mechanism 1 can also be in other shapes.

[0041] The reagent loading tray 2 is used to carry reagent containers containing reagents. Exemplarily, the reagent tray is set in a disc-shaped structure, with multiple positions for carrying reagent containers, and the reagent loading tray 2 can rotate and drive the reagent containers it carries to rotate, and is used to rotate the reagent containers to a specific position, such as a position where the reagent is sucked by the reagent dispensing mechanism 4.

[0042] The sample dispensing mechanism 3 is used to add the sample to the reaction container. Exemplarily, the sample dispensing mechanism 3 includes a moving part and a sample needle disposed on the moving part, and the moving part is used to drive the sample needle to move between different operating positions to absorb or discharge the sample. For example, the sample needle moves to absorb the sample carried by the sample supply mechanism 1, moves to the reaction container to be added, and discharges the sample into the reaction container.

[0043] The reagent dispensing mechanism 4 is used to add the reagent in the reagent container to the corresponding reaction container. For example, the reagent dispensing mechanism 4 is configured with a reagent needle, which moves to absorb the reagent in the reagent container carried by the reagent loading disk 2, moves to the reaction container to be added with the reagent, and discharges the reagent into the reaction container.

[0044] The reaction device 6 has at least one placement position, which is used to place a reaction container and incubate the reaction liquid in the reaction container, wherein the reaction liquid is obtained by mixing at least the sample provided by the sample dispensing mechanism 3 and the reagent provided by the reagent dispensing mechanism 4. For example, the reaction component can be a reaction disk, which is arranged in a disc-shaped structure, and the reaction disk can rotate and drive the reaction container in its placement position to rotate, so as to arrange the reaction container in the reaction disk and incubate the reaction liquid in the reaction container.

[0045] The detection device is used to detect the reaction liquid containing the sample and the reagent in the reaction container to obtain the sample detection result. For example, the detection device performs optical measurement analysis on the reaction liquid to be tested, and calculates the concentration of the component to be tested in the sample through the calibration curve.

[0046] It should be noted that the optical measurement analysis may be immunoassay, biochemical analysis, coagulation analysis, blood rheology analysis, and the like.

[0047] Exemplarily, in some embodiments, the sample analyzer further comprises a mixing mechanism 5, which is used to mix the reaction liquid in the reaction container. Exemplarily, the mixing mechanism 5 is provided with a stirring rod, which is used to mix the reaction liquid in the reaction container.

[0048] The number of the mixing mechanism 5 can be one or more.

[0049] For example, see Figure 2 and Figure 3 The reagent loading tray 2 includes a tray body, a tray cover 21 , a cold source and a loading cover 22 .

[0050] The tray cover 21 is disposed on the top of the tray body, and the tray cover 21 and the tray body together form a storage space for loading reagent containers. In some embodiments, the tray cover 21 and a portion of the tray body are integrally formed. In other embodiments, the tray cover 21 and the tray body are two independent parts, and the tray cover 21 is installed on the top of the tray cover 21 in a detachable or non-detachable manner. In the embodiment of the present application, the tray cover 21 and the tray body are described as two independent parts.

[0051] The tray cover 21 has a reagent loading port 21a for the reagent container to pass through. That is, when the reagent container needs to be taken in and out, the external reagent container is placed in the storage space through the reagent loading port 21a, and the reagent container in the storage space is taken out through the reagent loading port 21a. In this way, when taking in and out the reagent container, there is no need to open the tray cover 21.

[0052] The cold source is used to provide cold energy to the storage space so that the storage space can be maintained at the low temperature required by the reagent, for example, it can be above zero degrees and below fifteen degrees, or below zero degrees, and can be set according to actual use requirements.

[0053] The specific type of the cold source is not limited, for example, an evaporator of a heat pump system or a semiconductor refrigeration sheet can be used, which is not limited here. In some embodiments, the cold source also includes a fan, which is used to transport cold energy to the accommodation space, and is also conducive to promoting uniform distribution of cold energy in the accommodation space.

[0054] The loading cover 22 is openably disposed at the reagent loading port 21a. When the loading cover 22 closes the reagent loading port 21a, the accommodating space is a relatively closed space.

[0055] In the related art, after the loading cover closes the reagent loading port, air is easily leaked through the gap between the loading cover and the disk cover, causing the air around the reagent loading port of the disk cover and the loading cover to condense and form condensed water due to the temperature being lower than the dew point. When the sample analyzer is used for a long time, the condensed water may drip into the reagent container in the accommodating space to dilute the reagent and affect the test results, while also affecting the user experience.

[0056] In view of this, in the embodiment of the present application, the reagent loading disk 2 further includes an integrated sealing ring 23, that is, the sealing ring 23 is an integrated structure. The material of the sealing ring 23 is not limited, and can be silicone, rubber, etc.

[0057] See also Figure 6 The sealing ring 23 is arranged on the outer periphery of the reagent loading port 21a and / or on the loading cover 22. The sealing ring 23 is used to elastically deform under the clamping force of the loading cover 22 and the disk cover 21, thereby sealing the gap between the loading cover 22 and the disk cover 21.

[0058] It should be noted that the sealing ring 23 is arranged on the periphery of the reagent loading port 21a and / or on the loading cover 22, which includes three situations. The first situation is that the sealing ring 23 is arranged on the periphery of the reagent loading port 21a, the sealing ring 23 will not move with the loading cover 22, and the loading cover 22 is not provided with the sealing ring 23; the second situation is that the sealing ring 23 is arranged on the loading cover 22, the sealing ring 23 will move with the loading cover 22, and the disk cover 21 is not provided with the sealing ring 23; the third situation is that the number of the sealing rings 23 is at least two, the sealing ring 23 is provided on the periphery of the reagent loading port 21a, and the sealing ring 23 is also provided on the loading cover 22.

[0059] It should be noted that no matter the sealing ring 23 is disposed on the outer periphery of the reagent loading port 21 a or on the loading cover 22 , when the loading cover 22 closes the reagent loading port 21 a , the sealing ring 23 surrounds the outer periphery of the reagent loading port 21 a .

[0060] In the sample analyzer of the embodiment of the present application, since an integrated sealing ring 23 is provided between the loading cover 22 and the disk cover 21, when the loading cover 22 closes the reagent loading port 21a, the sealing ring 23 can continuously surround the outer circumference of the reagent loading port 21a, which can effectively improve the sealing performance between the loading cover 22 and the disk cover 21, and reduce the probability of cold air in the accommodating space leaking from the gap between the loading cover 22 and the disk cover 21, thereby reducing the probability of generating condensed water and improving the reliability of the reagent loading disk 2.

[0061] For example, see Figure 3 and Figure 7 The disk cover 21 is provided with a groove 21b, which surrounds the outer periphery of the reagent loading port 21a. It should be noted that the groove 21b is formed with a groove bottom wall and groove side walls on two opposite sides along the width direction, and the groove side walls and the groove bottom wall on both sides surround the groove 21b.

[0062] In some embodiments, the sealing ring 23 is accommodated in the groove 21b, that is, when the loading cover 22 opens the reagent loading port 21a, the sealing ring 23 is still accommodated in the groove 21b and does not move with the loading cover 22. In other embodiments, the sealing ring 23 is provided on the loading cover 22, and the groove 21b is used to cooperate with the sealing ring 23, that is, the sealing ring 23 moves with the loading cover 22, when the loading cover 22 closes the reagent loading port 21a, the sealing ring 23 enters the groove 21b, and when the loading cover 22 opens the reagent loading port 21a, the sealing ring 23 is separated from the groove 21b.

[0063] The groove 21 b can provide better positioning for the sealing ring 23 , thereby improving the sealing reliability of the sealing ring 23 .

[0064] For example, see Figure 7, the groove width h1 of the groove 21b is 1.1 to 1.3 times the width h2 of the sealing ring 23, that is, h1 = h2*(1.1 to 1.3), for example, 1.1 times, 1.13 times, 1.15 times, 1.18 times, 1.2 times, 1.22 times, 1.25 times, 1.27 times, 1.3 times, etc. The groove width of the groove 21b is the dimension perpendicular to the extending direction of the groove 21b.

[0065] In this embodiment, the groove 21 b allows the sealing ring 23 to undergo elastic deformation while controlling the elastic deformation of the sealing ring 23 within a suitable range, thereby reducing the probability of the sealing ring 23 being twisted or displaced due to excessive deformation.

[0066] For example, see Figure 3 The groove sidewall and the groove bottom wall of the groove 21b extend continuously in the direction surrounding the reagent loading port 21a, so that the groove 21b can be used to hold condensed water. The groove 21b is a continuously extending structure. Even if a small amount of condensed water is generated around the reagent loading port 21a by the loading cover 22 and the tray cover 21, the condensed water can be collected in the groove 21b to prevent the condensed water from dripping into the reagent container in the accommodation space.

[0067] It should be noted that the condensed water collected in the groove 21 b can be removed by natural evaporation or the like, or the user can absorb the condensed water with cloth, paper or the like after opening the loading cover 22 .

[0068] For example, see Figure 3 The disk cover 21 is formed with a first mounting surface 21c, and the first mounting surface 21c surrounds the outer circumference of the groove 21b.

[0069] See also Figure 4 The loading cover 22 is formed with a second mounting surface 22a; when the loading cover 22 closes the reagent loading port 21a, the first mounting surface 21c abuts against the second mounting surface 22a.

[0070] See also Figure 3 and Figure 7 The reagent loading tray 2 further includes a sealing cotton 24, which is disposed on the first mounting surface 21c and / or the second mounting surface 22a and is located at the periphery of the sealing ring 23. When the loading cover 22 closes the reagent loading port 21a, the first mounting surface 21c and the second mounting surface 22a clamp the sealing cotton 24 therebetween.

[0071] The sealing cotton 24 is arranged on the first mounting surface 21c and / or the second mounting surface 22a, including three situations. The first situation is that the sealing cotton 24 is arranged on the first mounting surface 21c, and the sealing cotton 24 is not arranged on the second mounting surface 22a; the second situation is that the sealing cotton 24 is arranged on the second mounting surface 22a, and the sealing cotton 24 is not arranged on the first mounting surface 21c; the third situation is that the sealing cotton 24 is respectively arranged on the first mounting surface 21c and the second mounting surface 22a.

[0072] Please note that Figure 7 The sealing cotton 24 is located at the periphery of the sealing ring 23, which means that when the loading cover 22 closes the reagent loading port 21a, the sealing cotton 24 is located at the periphery of the sealing ring 23, that is, the sealing cotton 24 and the sealing ring 23 will not squeeze each other along the direction in which the loading cover 22 closes the reagent loading port 21a.

[0073] In this embodiment, the sealing ring 23 is used to form a first seal, and the sealing cotton 24 is used to form a second seal. The two seals can further improve the sealing reliability and further reduce the probability of generating condensed water.

[0074] For example, see Figure 4 The loading cover 22 includes a cover shell 221 and a heat preservation structure 222. The peripheral edge of the cover shell 221 is folded toward the side where the disk cover 21 is located to form a folded edge 2211 (refer to Figure 7 ), the heat preservation structure 222 is arranged on the bottom side of the cover shell 221. The heat preservation structure 222 has a heat preservation effect, which is conducive to maintaining the low temperature in the accommodation space.

[0075] The material of the heat-insulating structure 222 is relatively soft, for example, it can be foam sponge, etc. The cover shell 221, as the appearance part of the loading cover 22, needs to have good structural strength, for example, it can be hard plastic.

[0076] In some embodiments, the sealing cotton 24 is disposed on the first mounting surface 21c, and the sealing ring 23 is disposed in the groove 21b, see Figure 7 The heat-insulating structure 222 is used to abut against the sealing ring 23 , and the folded edge 2211 is used to abut against the sealing cotton 24 .

[0077] The cooperation between the folded edge 2211 and the sealing cotton 24 is a cooperation between hard material and soft material. The sealing performance can be further enhanced by squeezing the sealing cotton 24 by the folded edge 2211.

[0078] Exemplarily, in an embodiment where the sealing cotton 24 is disposed on the first mounting surface 21c and the sealing ring 23 is disposed in the groove 21b, the top edge of the sealing ring 23 is higher than the top edge of the sealing cotton 24. Therefore, when the loading cover 22 closes the reagent loading port 21a, the second mounting surface 22a will squeeze the sealing cotton 24 and the sealing ring 23. Since the top edge of the sealing ring 23 is higher than the top edge of the sealing cotton 24, it is possible to ensure that the sealing ring 23 reliably undergoes elastic deformation.

[0079] The material of the sealing cotton 24 is not limited, for example, it can be polyurethane foam, polyester foam, natural rubber foam, synthetic rubber foam, etc.

[0080] For example, see Figure 3 , the reagent loading port 21a is roughly fan-shaped.

[0081] The sealing ring 23 includes an arc segment 231, a first straight segment 232, and a second straight segment 233 connected to each other. The arc segment 231 extends along the circumference of the disk cover 21. The first straight segment 232 and the second straight segment 233 extend from opposite ends of the arc segment 231 toward the center of the disk cover 21. The sealing ring 23 is generally fan-shaped. The transition connection between the first straight segment 232 and the second straight segment 233, the transition connection between the first straight segment 232 and the arc segment 231, and the transition connection between the second straight segment 233 and the arc segment 231 are smooth transitions.

[0082] The inventor of the present application has found through a large number of experiments and studies that in a comparison scheme in which a sealing ring 23 is provided but no sealing cotton is provided, a small amount of condensed water is sometimes generated in the arc segment and the two aforementioned corners, while basically no condensed water is generated in the remaining parts.

[0083] To this end, in the embodiment of the present application, the arc segment 231, the corner where the arc segment 231 and the first straight segment 232 are connected, and the corner where the arc segment 231 and the second straight segment 233 are connected are all provided with sealing cotton 24 on the side away from the reagent loading port 21a. In this way, the condensation phenomenon can be improved in a targeted manner.

[0084] It should be noted that, in some embodiments, the sealing cotton 24 may completely surround the circumference of the sealing ring 23 , that is, the shape of the sealing cotton 24 is similar to that of the sealing ring 23 .

[0085] In some other embodiments, please refer to Figure 3 The sealing cotton 24 is in the shape of strip segments, and the sealing cotton 24 is only arranged at the above-mentioned arc segment 231 and the two corners. The sealing cotton 24 may not be arranged on the periphery of the remaining parts of the sealing ring 23.

[0086] For example, see Figure 6 and Figure 8The disk cover 21 includes a main structure 211, and the main structure 211 is an integrated structure, for example, an integrated plastic part.

[0087] The disk cover 21 further includes a heat-insulating layer 212 , which is disposed on the inner side of the main structure 211 (the side facing the accommodation space).

[0088] For example, see Figure 3 , Figure 5 , Figure 6 and Figure 8 The reagent loading disk 2 includes a track structure 25, which is disposed on the disk cover 21, wherein the track structure 25 is formed with a track groove 25a, and a sampling hole 25b for the reagent needle to pass through is formed on the bottom wall of the track groove 25a.

[0089] It should be noted that the track groove 25a is located on the moving track of the reagent needle, and the track groove 25a has an opening along at least one end of its extension direction. For example, in some embodiments, the track of the reagent needle is arc-shaped, and the track groove 25a is also arc-shaped. The reagent needle enters the track groove 25a along the opening on one side of the track groove 25a, and the reagent needle is aligned with the sampling hole 25b, and enters the sample container in the containing space through the sampling hole 25b to absorb the reagent.

[0090] The number of the sampling holes 25b may be one, two or more, and is not limited here.

[0091] Exemplarily, the reagent loading tray 2 further includes a heating assembly 26, which is used to heat the track structure 25. Since the track structure 25 is formed with a sampling hole 25b, if the track structure 25 generates condensed water, the condensed water may also penetrate into the reagent container in the accommodation space from the sampling hole 25b. In the embodiment of the present application, the track structure 25 is heated by the heating assembly 26 so that the temperature of the track structure 25 is above the dew point temperature, so that the track structure 25 is not easy to generate condensed water.

[0092] The material of the track structure 25 is not limited. For example, in some embodiments, the track structure 25 can be hard plastic, ceramic, etc. In some embodiments, the track structure 25 is a metal piece, that is, the material of the track structure 25 is metal.

[0093] For some examples, see Figure 3 The disk cover 21 is formed with a mounting groove 21d, and the track structure 25 is arranged in the mounting groove 21d. The shape of the mounting groove 21d is adapted to the shape of the track structure 25.

[0094] See also Figure 8The heating assembly 26 is disposed between the side wall 251 of the track structure 25 and the groove wall 21a1 of the mounting groove 21d. The sampling hole 25b penetrates the bottom wall of the track structure 25. In this embodiment, the heating assembly 26 does not affect the arrangement of the sampling hole 25b, nor does it affect the appearance of the disk cover 21.

[0095] Exemplarily, the heating assembly 26 is disposed near the sampling hole 25 b so that the portion of the track structure 25 near the sampling hole 25 b has a relatively high temperature.

[0096] For some examples, see Figure 3 The heating assembly 26 includes a heating sheet 262 and a pressing plate 261, and the pressing plate 261 is connected to the side wall 251 of the track structure 25, for example, by screws. The pressing plate 261 and the side wall 251 of the track structure 25 fix the heating sheet 262 therebetween. The heating sheet 262 is in a sheet shape, which is also conducive to being arranged along the surface of the side wall 251 of the track structure 25, reducing the installation space required for the heating assembly 26, and having a compact structure.

[0097] In this embodiment, since the pressure plate 261 fixes the heating plate 262 on the track structure 25, before the track structure 25 is placed in the installation groove 21d, the heating component 26 and the track structure 25 can be assembled into a whole, and then the whole can be placed in the installation groove 21d, which is convenient for installation.

[0098] For example, see Figure 3 The heating assembly 26 further includes a buffer pad 263, which is disposed between the pressing plate 261 and the heating plate 262. The buffer pad 263 can fill the gap between the pressing plate 261 and the heating plate 262, so that the pressing plate 261 can reliably hold the heating plate 262 against the side wall of the track structure 25, and can also play a good buffering role and protect the heating plate 262.

[0099] The specific structure of the heating plate 262 is not limited. For example, the heating plate 262 can be a soft and bendable film structure. In other embodiments, the heating plate 262 can be a hard metal plate.

[0100] The embodiment of the present application also provides a reagent loading tray 2 for use in a sample analyzer.

[0101] The reagent loading tray 2 comprises a tray body, a tray cover 21 , a cold source and a loading cover 22 .

[0102] The tray cover 21 is disposed on the top of the tray body, and the tray cover 21 and the tray body together form a storage space for loading reagent containers. In some embodiments, the tray cover 21 and a portion of the tray body are integrally formed. In other embodiments, the tray cover 21 and the tray body are two independent parts, and the tray cover 21 is installed on the top of the tray cover 21 in a detachable or non-detachable manner. In the embodiment of the present application, the tray cover 21 and the tray body are described as two independent parts.

[0103] The tray cover 21 has a reagent loading port 21a for the reagent container to pass through. That is, when the reagent container needs to be taken in and out, the external reagent container is placed in the storage space through the reagent loading port 21a, and the reagent container in the storage space is taken out through the reagent loading port 21a. In this way, when taking in and out the reagent container, there is no need to open the tray cover 21.

[0104] The cold source is used to provide cold energy to the storage space so that the storage space can be maintained at the low temperature required by the reagent, for example, it can be above zero degrees and below fifteen degrees, or below zero degrees, and can be set according to actual use requirements.

[0105] The specific type of the cold source is not limited, for example, an evaporator of a heat pump system or a semiconductor refrigeration sheet can be used, which is not limited here. In some embodiments, the cold source also includes a fan, which is used to transport cold energy to the accommodation space, and is also conducive to promoting uniform distribution of cold energy in the accommodation space.

[0106] The loading cover 22 is openably disposed at the reagent loading port 21a. When the loading cover 22 closes the reagent loading port 21a, the accommodating space is a relatively closed space.

[0107] In the related art, after the loading cover closes the reagent loading port, air is easily leaked through the gap between the loading cover and the disk cover, causing the air around the reagent loading port of the disk cover and the loading cover to condense and form condensed water due to the temperature being lower than the dew point. When the sample analyzer is used for a long time, the condensed water may drip into the reagent container in the accommodating space to dilute the reagent and affect the test results, while also affecting the user experience.

[0108] In view of this, in the embodiment of the present application, the reagent loading disk 2 further includes an integrated sealing ring 23, that is, the sealing ring 23 is an integrated structure. The material of the sealing ring 23 is not limited, and can be silicone, rubber, etc.

[0109] See also Figure 6 The sealing ring 23 is arranged on the outer periphery of the reagent loading port 21a and / or on the loading cover 22. The sealing ring 23 is used to elastically deform under the clamping force of the loading cover 22 and the disk cover 21, thereby sealing the gap between the loading cover 22 and the disk cover 21.

[0110] It should be noted that the sealing ring 23 is arranged on the periphery of the reagent loading port 21a and / or on the loading cover 22, which includes three situations. The first situation is that the sealing ring 23 is arranged on the periphery of the reagent loading port 21a, the sealing ring 23 will not move with the loading cover 22, and the loading cover 22 is not provided with the sealing ring 23; the second situation is that the sealing ring 23 is arranged on the loading cover 22, the sealing ring 23 will move with the loading cover 22, and the disk cover 21 is not provided with the sealing ring 23; the third situation is that the number of the sealing rings 23 is at least two, the sealing ring 23 is provided on the periphery of the reagent loading port 21a, and the sealing ring 23 is also provided on the loading cover 22.

[0111] It should be noted that no matter the sealing ring 23 is disposed on the outer periphery of the reagent loading port 21 a or on the loading cover 22 , when the loading cover 22 closes the reagent loading port 21 a , the sealing ring 23 surrounds the outer periphery of the reagent loading port 21 a .

[0112] The reagent loading disk of the embodiment of the present application has an integrated sealing ring 23 provided between the loading cover 22 and the disk cover 21. When the loading cover 22 closes the reagent loading port 21a, the sealing ring 23 can continuously surround the outer circumference of the reagent loading port 21a, thereby effectively improving the sealing performance between the loading cover 22 and the disk cover 21 and reducing the probability of cold air in the accommodating space leaking from the gap between the loading cover 22 and the disk cover 21. Therefore, the probability of generating condensed water can be reduced, thereby improving the reliability of the reagent loading disk 2.

[0113] The reagent loading disk 2 may be the reagent loading disk 2 of any of the above embodiments, which will not be described in detail here.
