[0025] Please refer to Figure 1 , Figure 1 which is a three-dimensional structural schematic diagram of an embodiment of the incubation device 10 provided by the present application. The incubation device 10 in this embodiment includes an incubation base 11 and an incubation assembly 12.
[0026] Please also refer to Figure 2 and Figure 3 , Figure 2 which is Figure 1 a cross-sectional schematic diagram of the incubation device 10 in the F-F direction in Figure 3 which is Figure 2Schematic cross-sectional view of the incubation seat 11. The incubation seat 11 is formed with an accommodation space 101, and the incubation component 12 is disposed in the accommodation space 101.
[0027] Among them, the incubation component 12 is formed with an incubation groove 102 and a pick-up and placement opening 103 communicating with the incubation groove 102. The incubation groove 102 is used to accommodate the sample container 110. That is, in practical applications, the sample container 110 is placed into the incubation groove 102 through the pick-up and placement opening 103, so that the incubation component 12 heats and incubates the sample in the sample container 110. After the incubation is completed, the sample container 110 is taken out of the incubation groove 102 through the pick-up and placement opening 103.
[0028] It can be understood that the number of the incubation grooves 102 can be one or multiple, and can be set according to actual needs.
[0029] Please also refer to Figure 2 、 Figure 4 and Figure 5 , Figure 4 is Figure 1 the three-dimensional structure schematic diagram of the sample container 110 in Figure 5 is Figure 2 the enlarged schematic diagram of part M in . The sample container 110 includes an upper cup body 110a and a lower cup body 110b. The outer diameter Φ1 of the upper cup body 110a is greater than the outer diameter Φ2 of the lower cup body 110b. The incubation groove 102 includes an upper groove section 1021 and a lower groove section 1022. The groove diameter R1 of the upper groove section 1021 is greater than the groove diameter R2 of the lower groove section 1022. The upper groove section 1021 is used to accommodate the upper cup body 110a, and the lower groove section 1022 is used to accommodate the lower cup body 110b.
[0030] Furthermore, the incubation component 12 includes a first circumferential side wall 12a disposed on one side close to the upper groove section 1021. The first circumferential side wall 12a is used to fit with the upper cup body 110a, so as to position the sample container 110 through the first circumferential side wall 12a. On the one hand, in the embodiment of the present application, the positioning of the sample container 110 is to position the upper cup body 110a of the sample container 110 through the first circumferential side wall 12a. Compared with the prior art, the center of gravity position of the sample container 110 in the incubation groove 102 is reduced, and the risk that the sample container 110 is unstable in the center of gravity and tilts or even falls when shaking occurs is reduced or even eliminated. On the other hand, through the setting method that the groove diameter R1 of the upper groove section 1021 is greater than the groove diameter R2 of the lower groove section 1022, it is avoided that the incubation component 12 interferes with the sample container 110 during the process of placing the sample container 110 into the incubation groove 102, resulting in the situation that the sample container 110 cannot be placed into the incubation groove 102.
[0031] Specifically, the sample container 110 is as shown in Figure 2During the process of placing the incubation tank 102 in the direction A1 as shown, the lower cup 110b of the sample container 110 is first placed into the upper tank section 1021 through the loading and unloading opening 103, and then gradually placed into the lower tank section 1022. In order to prevent the incubation component 12 from interfering with the sample container 110 and causing the situation where the sample container 110 cannot be placed in the incubation tank 102, before the sample container 110 is placed in the incubation tank 102, the sample container 110 and the incubation tank 102 need to be aligned. However, in actual applications, if there are operating errors, the sample container 110 and the incubation tank 102 may not be aligned. Therefore, in this embodiment, by setting the groove diameter R1 of the upper tank section 1021 to be greater than the groove diameter R2 of the lower tank section 1022, the groove diameter R1 of the upper tank section 1021 is made greater than the outer diameter Φ2 of the lower cup 110b. Even if the sample container 110 and the incubation tank 102 are not aligned, the lower cup 110b of the sample container 110 can still be placed into the upper tank section 1021. After the lower cup 110b of the sample container 110 is placed in the upper tank section 1021, it is gradually placed into the lower tank section 1022 until the upper cup 110a of the sample container 110 is placed in the upper tank section 1021. At this time, the first circumferential side wall 12a fits with the upper cup 110a of the sample container 110, thereby realizing the positioning of the upper cup 110a of the sample container 110.
[0032] Furthermore, the incubation component 12 further includes a second circumferential side wall 12b disposed on one side close to the lower tank section 1022.
[0033] Optionally, the groove diameter R2 of the lower tank section 1022 is greater than the outer diameter Φ2 of the lower cup 110b, so that the second circumferential side wall 12b and the lower cup 110b are spaced apart to form a heating gap 104, and the heat emitted by the incubation component 12 is transmitted to the lower cup 110b through this heating gap 104.
[0034] Furthermore, the incubation component 12 further includes a bottom wall 12c disposed on one side close to the lower tank section 1022 and facing the opening direction of the loading and unloading opening 103, that is, in the direction A2 as shown Figure 2 The bottom wall 12c is provided with a positioning portion 12d, and the positioning portion 12d is used to be cooperatively arranged with the lower cup 110b, so that the positioning portion 12d positions the bottom of the sample container 110. Through this setting method, the positioning portion 12d and the above-mentioned first circumferential side wall 12a jointly position the sample container 110, improving the positioning effect of the sample container 110.
[0035] Specifically, a positioning structure (not shown in the figure) is provided at the bottom of the sample container 110. In this embodiment, the positioning structure is a positioning hole, and the positioning portion 12d is a positioning protrusion. After the lower body 110b of the sample container 110 is placed into the lower slot section 1022 from the upper slot section 1021, the positioning protrusion is inserted into the positioning hole, so that the two are in a matching state, realizing the positioning of the sample container 110.
[0036] Further referring to Figure 2 , the incubation tank 102 in this embodiment further includes an intermediate slot section 1023. The intermediate slot section 1023 is respectively communicated with the upper slot section 1021 and the lower slot section 1022. The slot diameter R3 of the intermediate slot section 1023 is smaller than the slot diameter R1 of the upper slot section 1021 and larger than the slot diameter R2 of the lower slot section 1022.
[0037] Among them, the intermediate slot section 1023 gradually decreases in the extending direction from the upper slot section 1021 to the lower slot section 1022, that is, in the direction A1 as shown in Figure 2 . Thus, during the process of the lower body 110b of the sample container 110 being placed into the lower slot section 1022 from the upper slot section 1021, it can gradually slide down to the lower slot section 1022, playing a guiding role for the process of the sample container 110 being placed from the upper slot section 1021 to the lower slot section 1022.
[0038] Furthermore, in this embodiment, a first guiding surface 12e is provided on one side of the incubation component 12 close to the access port 103. The first guiding surface 12e is inclined with respect to the opening direction A2 of the access port 103.
[0039] Specifically, as described above, during the process of the lower body 110b of the sample container 110 being placed into the upper slot section 1021 through the access port 103, if an operation error occurs and the sample container 110 is misaligned with the incubation tank 102, the lower body 110b of the sample container 110 first contacts the first guiding surface 12e, and then gradually slides down along the first guiding surface 12e to the upper slot section 1021, playing a guiding role for the process of the sample container 110 being placed from the access port 103 to the upper slot section 1021.
[0040] Optionally, the incubation component 12 in this embodiment includes a heating module 121 and a cover plate 122. The heating module 121 is disposed in the accommodation space 101 and forms the above-mentioned incubation tank 102. The cover plate 122 is pressed on the heating module 121 and forms the above-mentioned access port 103.
[0041] Among them, the diameter R4 of the access port 103 is larger than the slot diameter R1 of the upper slot section 1021, avoiding the risk that when the lower body 110b of the sample container 110 is placed into the access port 103, the incubation component 12 interferes with the lower body 110b of the sample container 110, resulting in the sample container 110 being unable to be placed into the access port 103.
[0042] Furthermore, the heating module 121 includes a heating layer 1211 and a heat conduction layer 1212. The heating layer 1211 is disposed within the accommodation space 101. The heat conduction layer 1212 is stacked on the heating layer 1211 and forms the above-mentioned incubation tank 102. The cover plate 122 is pressed against the heat conduction layer 1212. When the heating layer 1211 is energized and generates heat, the heat generated by the heating layer 1211 is conducted to the heat conduction layer 1212, and then conducted to the sample container 110, so as to heat and incubate the sample in the sample container 110.
[0043] Optionally, a pressing member 13 is further provided between the heating layer 1211 and the incubation seat 11. By cooperating the pressing member 13 with the cover plate 122, the heating layer 1211 and the heat conduction layer 1212 are pressed between the cover plate 122 and the pressing member 13, improving the structural firmness of the heating module 121.
[0044] The embodiment of the present application further provides a sample analyzer, which includes a detection device and the incubation device 10 in the above embodiment.
[0045] Among them, the detection device is used to detect the sample in the sample container 110 after the incubation is completed.
[0046] It can be understood that in this embodiment, the specific type of the sample analyzer and the specific detection method of the detection device are not limited. For example, the sample analyzer can be an analyzer for male diseases, female diseases, blood, etc.
[0047] The beneficial effects of the present application are as follows: Different from the prior art, the incubation device provided by the present application includes: an incubation base, which forms a receiving space; an incubation component, which is arranged in the receiving space, the incubation component forms an incubation groove and a pick-up and placement opening communicated with the incubation groove, the incubation groove is used for accommodating a sample container, the sample container includes an upper cup body and a lower cup body, the outer diameter of the upper cup body is larger than that of the lower cup body, the incubation groove includes an upper groove section and a lower groove section, the groove diameter of the upper groove section is larger than that of the lower groove section, the upper groove section is used for accommodating the upper cup body, the lower groove section is used for accommodating the lower cup body, the incubation component includes a first circumferential side wall arranged on one side close to the upper groove section, and the first circumferential side wall is used for fitting with the upper cup body, so as to position the sample container through the first circumferential side wall. On the one hand, in the implementation manner of the present application, the positioning of the sample container is carried out by positioning the upper cup body of the sample container through the first circumferential side wall. Compared with the prior art, the center of gravity position of the sample container in the incubation groove is reduced, and the risk of the sample container tilting or even falling due to the unstable center of gravity when shaking or the like occurs is reduced or even eliminated. On the other hand, by setting the groove diameter of the upper groove section to be larger than that of the lower groove section, the situation that the incubation component interferes with the sample container and causes the sample container to be unable to be placed in the incubation groove during the process of placing the sample container into the incubation groove is avoided.
