Abstract

This application discloses a carrier component, a counting plate, and a sample analyzer. By setting a heating block on a first carrier base to heat and incubate the sample on the first detection area, the incubation requirements of the sample on the first detection area are met, improving the detection efficiency of the sample analyzer for the sample on the first detection area. Furthermore, the heating function of the heating block does not affect the sample on the second detection area of ​​the counting plate, thus isolating the temperature influence of the first detection area from that of the second detection area, further improving the detection efficiency of the sample analyzer for the sample on the counting plate. Simultaneously, since the heating block is set on the first carrier base, there is no need to separately set up the detection channels or the sample reaction container; samples on both detection areas can be detected simultaneously, reducing the setup space of the sample analyzer, further improving the detection efficiency of the sample analyzer, and enhancing the user experience of the carrier component.

Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a carrier component, a counting plate, and a sample analyzer. Background Technology

[0002] During sample testing in the instrument, if the sample is tested in the RBC detection channel, it generally needs to be heated and incubated to improve the testing efficiency. However, when the sample is tested in the WBC or PLT detection channels, since incubation is not required, significant temperature influences can lead to no test results or inaccurate results due to temperature interference. Therefore, it is necessary to isolate the temperature of the RBC detection channel from that of the WBC / PLT detection channels.

[0003] In existing technologies, the RBC detection channel and the WBC / PLT detection channel are generally set up in separate reaction chambers within the instrument. The channels are relatively independent, so the temperature of the RBC detection channel will not affect the other channels. Alternatively, different sample reaction containers are set up, and samples for different detection items are reacted in different sample reaction containers. Then, the samples for RBC detection are heated and incubated separately before being sent to different detection channels for detection. Alternatively, the samples are tested in different detection channels at different times, and the samples are tested in the WBC / PLT detection channel first, and then the samples are tested in the RBC detection channel.

[0004] However, the above methods require a large installation space, which will increase the overall size of the instrument, increase the space occupied by the instrument, and increase the cost of independent detection channels / independent reaction containers, or prolong the detection time of samples and reduce the detection efficiency of samples. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a support component for a sample analyzer, which can be used to support a counting plate and a reagent compartment. The support component includes a first support base for supporting the counting plate.

[0006] The counting plate includes at least a first detection area and a second detection area, wherein the first detection area and the second detection area are arranged adjacent to each other along the length direction of the counting plate;

[0007] The first support is provided with a heating block, which is arranged corresponding to the first detection area. The heating block is used to contact the first detection area of ​​the counting plate when the counting plate is placed on the first support and to heat the sample carried on the first detection area.

[0008] The first support seat is provided with a support groove, and the counting plate is disposed in the support groove;

[0009] The first support seat is further provided with a fixing groove and a heat insulation groove. The fixing groove and the heat insulation groove are located at the bottom of the support groove. The fixing groove is corresponding to the first detection area, and the heat insulation groove is corresponding to the second detection area and the third detection area. The heating block is disposed in the fixing groove.

[0010] The first support seat has a plurality of protrusions on the side wall forming the fixed through groove. The plurality of protrusions are provided on at least two opposite side walls. The heating block passes through the fixed through groove. The protrusions abut against the heating block. The plurality of protrusions are used to fix the heating block in the fixed through groove.

[0011] The supporting component further includes a second supporting seat for supporting the reagent compartment. The first supporting seat and the second supporting seat are connected and configured, and at least one heat-insulating groove is provided at the connection between the first supporting seat and the second supporting seat.

[0012] The supporting assembly further includes a heat insulation component. The first supporting seat and the second supporting seat are connected through the heat insulation component. The first supporting seat has at least one heat insulation groove on the side near the heat insulation component, and / or the second supporting seat has at least one heat insulation groove on the side near the heat insulation component.

[0013] The supporting component further includes a positioning detection component, which is disposed on the first supporting base and spaced apart from the supporting groove, for detecting that the counting plate is placed in place.

[0014] The supporting component further includes a temperature sensor, which is disposed on the first supporting base and spaced apart from the heating block, for detecting the temperature on the heating block.

[0015] To solve the above-mentioned technical problems, this application also provides a counting plate, which is applied to the carrier component as described above. The counting plate includes a first detection area and a second detection area. The first detection area and the second detection area are arranged adjacent to each other along the length direction of the counting plate. The first detection area is used to load samples that need to be heated, and the second detection area is used to load samples that do not need to be heated.

[0016] The counting plate is provided with a heat insulation groove, which extends along the width direction of the counting plate and is located between the first detection area and the second detection area.

[0017] To address the aforementioned technical problems, this application also provides a sample analyzer, including a counting plate, a reagent chamber, a pipetting assembly, a detection assembly, and a support assembly as described above. The support assembly is spaced apart from the pipetting assembly and the detection assembly. The support assembly supports the reagent chamber and the counting plate. The pipetting assembly moves the sample in the reagent chamber onto the counting plate. A heating block on the support assembly heats the sample in the first detection area of ​​the counting plate. The support assembly also moves the counting plate to the detection assembly. The detection assembly detects the samples in the first and second detection areas on the counting plate.

[0018] The beneficial effects of this application are as follows: Unlike existing technologies, the carrier component provided in this application is applied to a sample analyzer and can be used to support a counting plate. The carrier component includes a first carrier base for supporting the counting plate. A heating block is provided on the first carrier base, and the heating block is correspondingly arranged with respect to the first detection area of ​​the counting plate. The heating block is used to contact the first detection area of ​​the counting plate when the counting plate is placed on the first carrier base, and to heat the sample supported on the first detection area. By setting a heating block on the first carrier base to heat the sample supported on the first detection area, the heating and incubation requirements of the sample on the first detection area are met, improving the detection efficiency of the sample analyzer for the sample on the first detection area. Furthermore, the heating function of the heating block does not affect the sample on the second detection area of ​​the counting plate, thus isolating the temperature influence of the first detection area from the second detection area and improving the detection efficiency of the sample analyzer for the sample on the counting plate. Meanwhile, since the heating block is set on the first support, there is no need to set up the detection channel separately or the sample reaction container separately. Samples in the two detection areas can be detected simultaneously, which reduces the setup space of the sample analyzer, further improves the detection efficiency of the sample analyzer, and enhances the user experience of the support component.

[0029] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0030] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the carrier component of this application. The carrier component 1 provided in this application is applied to a sample analyzer and can be used to support the counting plate 2. The carrier component 1 includes a first support base 11, which is used to support the counting plate 2. In one embodiment, the counting plate 2 is a commercially available consumable, and the specific structure of the counting plate 2 will not be described in detail here.

[0034] Please continue reading for more details. Figure 2 , Figure 2 This is a schematic diagram of a counting plate according to an embodiment of the present application. The counting plate 2 includes a first detection area 21 and a second detection area 22, which are arranged adjacent to each other along the length of the counting plate 2. The first detection area 21 may be connected to the second detection area 22, or the first detection area 21 and the second detection area 22 may be spaced apart.

[0035] In one embodiment, the first detection area 21 can be an RBC detection area, and the second detection area 22 can be a WBC detection area. In other embodiments, the specific detection items of the first detection area 21 and the second detection area 22 can be changed according to the actual detection items performed by the user, and this application does not impose any restrictions on this.

[0036] In another embodiment, the counting plate 2 may further include a third detection area 23. The first detection area 21, the second detection area 22, and the third detection area 23 may be arranged adjacent to each other along the length of the counting plate 2. In one embodiment, the first detection area 21 may be an RBC detection area, the second detection area 22 may be a WBC detection area, and the third detection area 23 may be a PLT detection area. Increasing the number of detection areas on the counting plate 2 allows for simultaneous testing of more items on the sample, improving the efficiency of sample testing. It is understood that other numbers of detection areas may be provided on the counting plate 2, which can be set according to user needs, and this application does not limit this.

[0037] For further details, please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of the second embodiment of the carrier component of this application. A heating block 13 is provided on the first carrier 11. The heating block 13 is correspondingly arranged with the first detection area 21. The heating block 13 is used to contact the first detection area 21 of the counting plate 2 when the counting plate 2 is placed on the first carrier 11, and to heat the sample carried on the first detection area 21.

[0038] As mentioned above, the first detection area 21 can be a detection area for RBC detection or other detection items that require heating, and the second detection area 22 can be a WBC detection area, a PLT detection area, or other detection areas that do not require heating. Therefore, before testing the sample in the first detection area 21, the sample in the first detection area 21 needs to be heated for incubation to improve the detection efficiency of the sample in the first detection area 21. The sample in the second detection area 22 should not be affected by temperature to avoid affecting the detection efficiency of the sample in the second detection area 22.

[0039] Therefore, this embodiment proposes that the heating block 13 is correspondingly arranged with the first detection area 21. Thus, when the counting plate 2 is placed on the first support 11, the heating block 13 can contact the first detection area 21, transferring heat to it and heating the sample in the first detection area 21 for incubation, thereby improving the detection efficiency of the sample in the first detection area 21. Simultaneously, since the heating block 13 does not contact the second detection area 22, it will not transfer heat to the second detection area 22, and the sample in the second detection area 22 will not be affected by temperature, ensuring the detection efficiency of the sample in the second detection area 22. This saves the space occupied by the heating block 13 and allows for simultaneous detection of samples in both the first and second detection areas 21 and 22 on the counting plate 2, improving the efficiency of sample detection. This improves the operating efficiency of the sample analyzer, enhances the practicality of the support component 1, and improves the user experience of the support component 1.

[0040] In one embodiment, the second detection area 22 may be a detection area that needs to be heated, such as an RBC detection area. In this case, the heating block 13 may be set in the corresponding second detection area 22. It is understood that the specific setting position of the heating block 13 may change as the detection area to be heated changes, and this application does not limit this.

[0041] Alternatively, please continue reading Figure 3 In this embodiment, the first support seat 11 is provided with a support groove 111, and the counting plate 2 is disposed in the support groove 111.

[0042] Furthermore, the bearing groove 111 can restrict the counting plate 2, preventing the counting plate 2 from falling off relative to the bearing component 1 when the bearing component 1 moves the counting plate 2, thereby improving the safety of the counting plate 2 placed on the first bearing seat 11 and further enhancing the user's experience with the bearing component 1.

[0043] For further details, please refer to the following: Figure 4 , Figure 4 This is a structural schematic diagram of the third embodiment of the bearing component of this application. The first bearing seat 11 is also provided with a fixing groove 112 and a heat insulation groove 113. The fixing groove 112 and the heat insulation groove 113 are located at the bottom of the bearing groove 111. The fixing groove 112 is correspondingly arranged with the first detection area 21, and the heat insulation groove 113 is correspondingly arranged with the second detection area 22. The heating block 13 is disposed in the fixing groove 112.

[0044] Specifically, since the fixed through groove 112 is correspondingly set to the first detection area 21 and the heating block 13 is set in the fixed through groove 112, the heating block 13 can be correspondingly set to the first detection area 21. When the first detection area 21 is placed in the bearing groove 111, the first detection area 21 can contact the heating block 13. The heating block 13 heats and incubates the sample on the first detection area 21 to improve the detection efficiency of the sample on the first detection area 21.

[0045] The heat insulation groove 113 is correspondingly set to the second detection area 22. When the counting plate 2 is placed in the bearing groove 111, the heat insulation groove 113 is not filled, which can form a cavity between the second detection area 22 of the counting plate 2 and the first bearing seat 11. This prevents the heat on the heating block 13 from being transferred to the second detection area 22 of the counting plate 2 through the first bearing seat 11, thus avoiding any impact on the sample in the second detection area 22. This further improves the practicality of the bearing component 1 and enhances the user's experience with the bearing component 1.

[0046] In one embodiment, the depth of the heat insulation groove 113 can be greater than 0.5 mm, such as 0.5 mm, 1 mm, 1.5 mm, 2 mm, etc., so as to form a sufficiently large cavity between the second detection area 22 and the first support seat 11 to prevent heat from the first support seat 11 from being transferred to the second detection area 22.

[0047] It is understandable that when the radial cross-sectional area of ​​the heat insulation groove 113 is small, a larger depth can be chosen to ensure that a sufficiently large cavity is formed between the second detection area 22 and the first support seat 11. Conversely, when the radial cross-sectional area of ​​the heat insulation groove 113 is large, a smaller depth can be chosen to reduce the processing difficulty of the heat insulation groove 113. However, even when the radial cross-sectional area of ​​the heat insulation groove 113 is sufficiently large, a smaller depth is not necessarily better. The thermal conductivity of the air in the environment must also be considered to avoid the heat insulation groove 113 being too shallow. If the depth is too shallow, the distance between the plane at the bottom of the heat insulation groove 113 and the surface of the counting plate 2 will be too small when the counting plate 2 is placed in the support groove 111. In this case, the cavity formed by the heat insulation groove 113 will not provide heat insulation, and the heat on the first support seat 11 can still be transferred to the counting plate 2 through the cavity, affecting the sample on the second detection area 22. Therefore, this application proposes that the depth of the heat insulation groove 113 be greater than 0.5 mm to ensure the heat insulation effect of the cavity formed by the heat insulation groove 113.

[0048] Optional, please refer to Figure 5 , Figure 5 yes Figure 3 The schematic diagram of region A in the bearing assembly shows that the first bearing seat 11 has multiple protrusions 1121 on its sidewall forming the fixing through groove 112. These protrusions 1121 are located on at least two opposite sidewalls. Figure 5 As shown, the heating block 13 is rectangular, so the radial cross-sectional shape of the fixing groove 112 can be rectangular, including a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall connected in sequence. The first sidewall and the third sidewall are arranged opposite to each other, and the second sidewall and the fourth sidewall are arranged opposite to each other. Multiple protrusions 1121 can be distributed on the first sidewall and the third sidewall, or on the second sidewall and the fourth sidewall. Thus, when the heating block 13 is disposed in the fixing groove 112, the multiple protrusions 1121 can apply force to the opposite sides of the heating block 13 to fix the heating block 13 in the fixing groove 112.

[0049] Meanwhile, since the protrusion 1121 abuts against the heating block 13, that is, the surface contact between the heating block 13 and the side wall is changed to the point contact between the heating block 13 and the protrusion 1121, the contact area between the heating block 13 and the side wall is reduced, thereby reducing the heat transferred from the heating block 13 to the first support seat 11, further reducing the impact of heat on the sample in the second detection area 22 on the counting plate 2, and improving the practicality of the support assembly 1.

[0050] In another embodiment, multiple protrusions 1121 may also be distributed on the first sidewall, the second sidewall, the third sidewall, and the fourth sidewall to further improve the fixing efficiency of the heating block 13.

[0051] In other embodiments, if the heating block 13 has other shapes and structures, the specific cross-sectional shape of the fixing groove 112 can be changed accordingly, and the specific setting position and specific setting number of the multiple protrusions 1121 can also be changed accordingly. Based on the fixing of the heating block 13, this application does not impose any restrictions on this.

[0052] Optional, please refer back to the previous section. Figure 1 The support component 1 also includes a second support seat 12, which is used to support the reagent chamber 3. The first support seat 11 and the second support seat 12 are connected. In one embodiment, the first support seat 11 and the second support seat 12 can be an integral structure, and at least one heat-insulating groove (not shown) is provided at the connection between the first support seat 11 and the second support seat 12.

[0053] The heat-insulating channel can reduce the connection area between the first support seat 11 and the second support seat 12, thereby reducing the heat transferred from the first support seat 11 to the second support seat 12, avoiding the heat from affecting the sample in the reagent chamber 3 on the second support seat 12, and improving the practicality of the support component 1.

[0054] Alternatively, please continue reading Figure 6 , Figure 6 This is a schematic diagram of the structure of the fourth embodiment of the carrier component of this application. In this embodiment, the first carrier 11 and the second carrier 12 can be separate structures, and the carrier component 1 includes a heat insulation member 14, through which the first carrier 11 and the second carrier 12 are connected. In one embodiment, the heat insulation member 14 can be a heat insulation pad. Furthermore, the heat insulation member 14 can isolate the heat on the first carrier 11 from the second carrier 12, preventing the heat on the first carrier 11 from being transferred to the second carrier 12, thus ensuring the safety of the sample in the reagent chamber 3 carried by the second carrier 12.

[0055] Furthermore, the first support 11 is provided with at least one heat insulation groove 114 on the side near the heat insulation member 14, and / or the second support 12 is provided with at least one heat insulation groove 114 on the side near the heat insulation member 14.

[0056] In one embodiment, at least one heat-insulating groove 114 may be provided on the side of the first support 11 near the heat insulation member 14, so that at least one heat-insulating groove 114 is provided at the connection between the first support 11 and the second support 12, thereby reducing the contact area between the first support 11 and the heat insulation member 14 and reducing the heat transfer from the first support 11 to the heat insulation member 14.

[0057] In another embodiment, the second support 12 may have at least one heat-insulating groove 114 on the side near the heat insulation member 14 to reduce the contact area between the second support 12 and the heat insulation member 14, thereby further reducing the heat transferred from the first support 11 to the second support 12.

[0058] In other embodiments, the first support 11 may have at least one heat-insulating groove 114 on the side near the heat insulation member 14, and the second support 12 may also have at least one heat-insulating groove 114 on the side near the heat insulation member 14. This reduces the contact area between the first support 11 and the second support 12 and the heat insulation member 14, reduces the heat transferred from the first support 11 to the second support 12, improves the safety of the sample in the reagent chamber 3 carried by the second support 12, and improves the practicality of the support assembly 1.

[0059] Optionally, the first support 11 and the second support 12 may be made of different materials so that the thermal conductivity of the second support 12 is less than that of the first support 11, thereby further preventing the heat on the first support 11 from being transferred to the second support 12 and affecting the sample in the reagent chamber 3 on the second support 12, and improving the practicality of the support assembly 1.

[0060] Optional, please refer back to the previous section. Figure 1 The supporting component 1 also includes a heat insulation component 15, which is disposed on the side of the first supporting seat 11 away from the supporting groove 111 and covers the heating block 13 to keep the heating block 13 warm and prevent the heat generated by the heating block 13 from being lost through the air, thus affecting the heating efficiency of the heating block 13 on the sample in the first detection area 21.

[0061] In one embodiment, the insulation element 15 can be insulation cotton.

[0062] Optionally, the support component 1 may also include a temperature sensor (not shown). The temperature sensor is disposed on the first support 11 and spaced apart from the heating block 13. It is used to detect the temperature on the heating block 13. The user can obtain the current heating temperature of the heating block 13 through the temperature sensor and adjust the temperature on the heating block 13 according to the needs.

[0063] Optionally, the bearing assembly 1 further includes a positioning detection assembly 16, which is disposed on the first bearing seat 11 and spaced apart from the bearing groove 111, for detecting that the counting plate 2 is placed in the correct position.

[0064] In one embodiment, the positioning detection component 16 can be an optocoupler. When the counting plate 2 is not placed in the supporting groove 111, the light beam generated by the optocoupler will not be blocked, and the positioning detection component 16 can respond to the situation where the counting plate 2 is not positioned. Conversely, when the light beam generated by the optocoupler is blocked, i.e., when the counting plate 2 is placed in the supporting groove 111, the positioning detection component 16 can respond to the situation where the counting plate 2 is not positioned but the supporting component 1 proceeds to the next step, thus improving the orderly operation. For example, the supporting component 1 will only move the counting plate 2 after the positioning detection component 16 responds to the situation where the counting plate 2 is positioned.

[0065] In summary, the carrier component 1 provided in this application, by setting a heating block 13 on the first carrier 11 to heat and incubate the sample carried on the first detection area 21, meets the incubation requirements of the sample on the first detection area 21, improves the detection efficiency of the sample analyzer for the sample on the first detection area 21, and the heating function of the heating block 13 does not affect the sample on the second detection area 22 of the counting plate 2, thus isolating the temperature influence of the first detection area 21 from the second detection area 22, and improving the detection efficiency of the sample analyzer for the sample on the counting plate 2. At the same time, since the heating block 13 is set on the first carrier 11, there is no need to separately set up the detection channel or the sample reaction container. The samples on the two detection areas can be detected simultaneously, reducing the setup space of the sample analyzer, further improving the detection efficiency of the sample analyzer for the sample, and enhancing the user experience of the carrier component 1.

[0066] This application also provides a counting plate 2, applied to the support component 1 as described above. Please refer to [link to relevant documentation]. Figure 7 , Figure 7 This is a schematic diagram of another embodiment of the counting plate of this application.

[0067] In this embodiment, the counting plate 2 includes a first detection area 21 and a second detection area 22. The first detection area 21 and the second detection area 22 are arranged adjacent to each other along the length direction of the counting plate 2. The first detection area 21 and the second detection area 22 are places where samples are subjected to different detection items.

[0068] The first detection area 21 is used to load samples that require heating, and is the location for detection items that require heating and incubation; the second detection area 22 is used to load samples that do not require heating, and is the location for detection items that do not require heating and incubation.

[0069] Furthermore, the counting plate 2 is also provided with a heat insulation groove 24, which extends along the width of the counting plate 2 and is located between the first detection area 21 and the second detection area 22. The heat insulation groove 24 isolates the heat transferred from the heating block 13 to the first detection area 21, confining the heat to the first detection area 21 and preventing heat transfer from the first detection area 21 to the second detection area 22, thus avoiding any impact on the sample in the second detection area 22. This further enables separate heating and incubation of the sample in the first detection area 21, while the sample in the second detection area 22 remains unaffected by temperature, improving the practicality of the counting plate 2.

[0070] In one embodiment, the position of the heat insulation groove 24 can be changed according to the location to be heated, so as to isolate the heated detection area from its adjacent detection areas. For example, if the counting plate 2 also includes a third detection area 23, and the detection area to be heated is the second detection area 22, then two heat insulation grooves 24 can be provided on the counting plate 2, respectively between the second detection area 22 and the first detection area 21, and between the second detection area 22 and the third detection area 23, to prevent the heat on the second detection area 22 from being transferred to the first detection area 21 and / or the third detection area 23.

[0071] This application also proposes a sample analyzer (not shown), including a counting plate 2 (which may be a counting plate 2 with or without a heat insulation groove 24), a reagent chamber 3, a pipetting assembly, a detection assembly, and a carrier assembly 1. The carrier assembly 1 is spaced apart from the pipetting assembly and the detection assembly. The carrier assembly 1 is used to carry the reagent chamber 3 and the counting plate 2. The pipetting assembly is used to move the sample in the reagent chamber onto the counting plate 2. The heating block 13 on the carrier assembly 1 is used to heat the sample on the first detection area 21 of the counting plate 2. The carrier assembly 1 is also used to move the counting plate 2 to the detection assembly, which is used to detect the samples on the first detection area 21 and the second detection area 22 of the counting plate 2.

[0072] Specifically, reagent compartment 3 can hold samples and detection auxiliary reagents (such as diluents, stains, hemolysins, etc.). After the counting plate 2 and reagent compartment 3 are placed on the carrier component 1, the pipetting assembly can pre-treat the samples in reagent compartment 3, such as mixing the samples with detection auxiliary reagents, and then the pipetting assembly moves the pre-treated samples to the detection areas on the counting plate 2. It can be understood that since the detection areas on the counting plate 2 are for different detection items on the samples, the pipetting assembly can pre-treat the samples differently in reagent compartment 3 before moving the samples to the corresponding detection areas.

[0073] The heating block 13 generates heat and transfers it to the first detection area 21 of the counting plate 2 to heat and incubate the sample on the first detection area 21. At the same time, the carrier component 1 can move the counting plate 2 and the reagent chamber 3 to the detection component. After the sample on the first detection area 21 has been incubated, the detection component performs different sample tests on the samples in each detection area on the counting plate 2.

[0074] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
