[0031] See also Figure 1 , Figure 1 The detection device 1 provided in the embodiment of the present application is used to detect a sample and maintain a constant temperature state of the sample during the detection process, and includes a substrate 11, a heating element 12, a first reaction container 13 and a second reaction container 14.

[0032] Among them, the heating component 12 is arranged on the base body 11. The first reaction container 13 and the second reaction container 14 are used to load the samples to be detected. The first reaction container 13 and the second reaction container 14 are respectively arranged on the base body 11 and are symmetrically arranged on both sides of the axis with the central axis of the heating component 12 as the axis. The heating component 12 is used to heat the base body 11 to heat the samples in the first reaction container 13 and the second reaction container 14, so as to keep the samples at a constant temperature during the detection of the samples in the first reaction container 13 and the second reaction container 14 by the detection device 1, and improve the detection efficiency of the detection device 1 for the samples. Among them, the sample can be understood as a blood sample, or the sample can be understood as the sample to be detected after mixing the blood sample and the reagent; the sample can also be understood as the reagent for preparing the sample solution to be detected.

[0033] Specifically, since the first reaction container 13 and the second reaction container 14 are symmetrically arranged on the base body 11 with the central axis of the heating component 12 as the symmetry axis, that is, the distance between the heating component 12 and the first reaction container 13 is equal to the distance between the heating component 12 and the second reaction container 14. Furthermore, the heat conduction amount of the heating component 12 to the first reaction container 13 is equal to the heat conduction amount of the heating component 12 to the second reaction container 14, that is, it is ensured that on one base body 11, the temperatures of the samples in the first reaction container 13 and the second reaction container 14 are kept the same, so that the samples in the first reaction container 13 and the second reaction container 14 are kept at a constant temperature at the same temperature, improving the detection efficiency of the detection device 1 for the samples to be detected in the first reaction container 13 and the second reaction container 14, and improving the user experience of using the detection device 1.

[0034] At the same time, the first reaction container 13 and the second reaction container 14 are symmetrically arranged with the central axis of the heating component 12 as the symmetry axis, so that on one base body 11, one heating component 12 heats the samples in two reaction containers, improving the heating efficiency of the heating component 12. The detection device 1 does not need to set a heating device for one reaction container, reducing the volume of the detection device 1 and further enhancing the user experience of using the detection device 1.

[0035] In an embodiment, the shape of the heating component 12 can be rod-shaped, and the radial cross-sectional graph of the heating component 12 is a centrosymmetric graph, further ensuring that the distance between the heating component 12 and the first reaction container 13 is equal to the distance between the heating component 12 and the second reaction container 14. In other embodiments, the heating component 12 can also be other left-right symmetric shapes with the central axis as the symmetry axis, and the present application does not limit this.

[0036] Optionally, the substrate 11 includes a first bearing portion 111 and a second bearing portion 112. The first bearing portion 111 and the second bearing portion 112 are respectively disposed on both sides of the axis and are symmetrically arranged. The first reaction vessel 13 is disposed on the first bearing portion 111, and the second reaction vessel 14 is disposed on the second bearing portion 112.

[0037] Specifically, since the first bearing portion 111 and the second bearing portion 112 are symmetrical about the central axis of the heating element 12, that is, the mass and volume of the first bearing portion 111 and the second bearing portion 112 are equal, which further ensures that the heat conducted by the heating element 12 to the first reaction vessel 13 through the first bearing portion 111 is equal to the heat conducted by the heating element 12 to the second reaction vessel 14 through the second bearing portion 112, ensuring that the samples in the first reaction vessel 13 and the second reaction vessel 14 are kept at a constant temperature at the same temperature, and improving the detection efficiency of the detection device 1 for the samples to be detected in the first reaction vessel 13 and the samples to be detected in the second reaction vessel 14.

[0038] In one embodiment, the first bearing portion 111 is provided with a first placement groove, and the first reaction vessel 13 is located in the first placement groove; the second bearing portion 112 is provided with a second placement groove, and the second reaction vessel 14 is located in the second placement groove.

[0039] Wherein, both the first bearing portion 111 and the second bearing portion 112 are heat-conducting members. The first bearing portion 111 is used to conduct the heat of the heating element 12 to the first reaction vessel 13, and the second bearing portion 112 is used to conduct the heat of the heating element 12 to the second reaction vessel 14, so as to heat the samples to be detected in the first reaction vessel 13 and the samples to be detected in the second reaction vessel 14.

[0040] Wherein, the radial cross-sectional area of the first placement groove is equal to the radial cross-sectional area of the second placement groove, and the radial cross-sectional area of the first reaction vessel 13 is equal to the radial cross-sectional area of the second reaction vessel 14.

[0041] That is, the radial cross-sectional areas of the first placement groove and the second placement groove are equal, and the radial cross-sectional areas of the first reaction vessel 13 and the second reaction vessel 14 are equal. Since the first reaction vessel 13 and the second reaction vessel 14 are symmetrically arranged about the central axis of the heating element 12, it is strictly ensured that the first bearing portion 111, the first placement groove and the first reaction vessel 13, and the second bearing portion 112, the second placement groove and the second reaction vessel 14 are symmetrically arranged about the central axis of the heating element 12, ensuring that the heat of the heating element 12 is evenly transferred to the first reaction vessel 13 and the second reaction vessel 14.

[0042] In one embodiment, the radial cross-sectional area of the first placement groove may also be equal to the radial cross-sectional area of the first reaction vessel 13, and the radial cross-sectional area of the second placement groove may also be equal to the radial cross-sectional area of the second reaction vessel 14. When the first reaction vessel 13 is placed in the first placement groove, the outer wall of the first reaction vessel 13 contacts the groove wall of the first placement groove. When the second reaction vessel 14 is placed in the second placement groove, the outer wall of the second reaction vessel 14 contacts the groove wall of the second placement groove. This can better achieve heat transfer between the substrate 11 and the first reaction vessel 13 and the second reaction vessel 14, so that the samples to be detected in the first reaction vessel 13 and the second reaction vessel 14 are at the same temperature and maintained in a constant temperature state, improving the heating efficiency of the heating component 12, improving the detection efficiency of the detection device 1 for the samples to be detected in the first reaction vessel 13 and the second reaction vessel 14, and enhancing the user experience of using the detection device 1.

[0043] Optionally, the detection device 1 further includes a detection component 15, which is arranged on the substrate 11 and is used to detect the samples in the first reaction vessel 13 and the second reaction vessel 14.

[0044] In one embodiment, the first bearing portion 111 is provided with a first through hole 113, the extending direction of the first through hole 113 is perpendicular to the extending direction of the first placement groove, and one end of the first through hole 113 communicates with the first placement groove; the second bearing portion 112 is provided with a second through hole 114, the extending direction of the second through hole 114 is perpendicular to the extending direction of the second placement groove, and one end of the second through hole 114 communicates with the second placement groove.

[0045] The detection component 15 includes a first light beam emitter 151, a second light beam emitter 152, a first light beam receiver and a second light beam receiver. The first light beam emitter 151 and the first light beam receiver are arranged on the substrate 11 through the first through hole 113, and the first light beam emitter 151 and the second light beam receiver are arranged on opposite sides of the first reaction vessel 13; the second light beam emitter 152 and the second light beam receiver are arranged on the substrate 11 through the second through hole 114, and the second light beam emitter 152 and the second light beam receiver are arranged on opposite sides of the second reaction vessel 14.

[0046] Furthermore, the light beam emitted by the first light beam emitter 151 disposed at the first through hole 113 enters the first placement groove through the first through hole 113 and irradiates the first reaction vessel 13 located in the first placement groove. Then, the first light beam receiver receives the light beam passing through the first reaction vessel 13 to detect the sample to be detected in the first reaction vessel 13. The light beam emitted by the second light beam emitter 152 disposed at the second through hole 114 enters the second placement groove through the second through hole 114 and irradiates the second reaction vessel 14 located in the second placement groove. Then, the second light beam receiver receives the light beam passing through the second reaction vessel 14 to detect the sample to be detected in the second reaction vessel 14.

[0047] The light beam emitted by the first light beam emitter 151 enters the first reaction vessel 13 through the sealed first through hole 113, and the light beam emitted by the second light beam emitter 152 enters the second reaction vessel 14 through the sealed second through hole 114, avoiding the influence of the external environment on the light beams emitted by the first light beam emitter 151 and the second light beam emitter 152, and improving the quality of the light beams emitted by the first light beam emitter 151 and the second light beam emitter 152. At the same time, the first light beam receiver and the second light beam receiver are also separated from the outside world, avoiding the influence of the received light beam by the external environment, further improving the quality of the light beam received by the first light beam receiver and the second light beam receiver, and improving the detection efficiency of the detection component 1 for the samples in the first reaction vessel 13 and the second reaction vessel 14.

[0048] Optionally, the distance between the connection of the first through hole 113 and the first placement groove and the bottom of the first placement groove is less than or equal to one-half of the depth of the first placement groove. The distance between the connection of the second through hole 114 and the second placement groove and the bottom of the second placement groove is less than or equal to one-half of the depth of the second placement groove.

[0049] Furthermore, the light beam emitted by the first light beam emitter 151 can irradiate the lower region of the first reaction vessel 13, and the light beam emitted by the second light beam emitter 152 can irradiate the lower region of the second reaction vessel 14, irradiating the samples in the first reaction vessel 13 and the second reaction vessel 14, and avoiding the situation that the light beams emitted by the first light beam emitter 151 and the second light beam emitter 152 irradiate the area in the reaction vessel without samples, which affects the detection efficiency of the detection device 1 for the samples, and improving the detection efficiency of the detection device 1 for the samples.

[0050] Specifically, the distance between the connection of the first through hole 113 and the first placement groove and the bottom of the first placement groove can be one-half, two-fifths, one-third, etc. of the depth of the first placement groove; the distance between the connection of the second through hole 114 and the second placement groove and the bottom of the second placement groove can be one-half, two-fifths, one-third, etc. of the depth of the second placement groove. This application does not limit the specific values of the distance between the connection of the first through hole 113 and the first placement groove and the bottom of the first placement groove, and the distance between the connection of the second through hole 114 and the second placement groove and the bottom of the second placement groove.

[0051] In one embodiment, the distance between the connection of the first through hole 113 and the first placement groove and the bottom of the first placement groove can be equal to the distance between the connection of the second through hole 114 and the second placement groove and the bottom of the second placement groove.

[0052] In another embodiment, the distance between the connection of the first through hole 113 and the first placement groove and the bottom of the first placement groove can be greater than one-fourth of the depth of the first placement groove; the distance between the connection of the second through hole 114 and the second placement groove and the bottom of the second placement groove can be greater than one-fourth of the depth of the second placement groove, so as to prevent the light beams emitted by the first light beam emitter 151 and the second light beam emitter 152 from hitting the bottom of the reaction vessel instead of the sample area in the reaction vessel, and improve the detection efficiency of the detection device 1 for the sample.

[0053] Optionally, the detection device 1 further includes a temperature sensor 16, which is disposed on the base 11 to detect the temperature on the base 11, and thus detect the temperatures of the samples in the first reaction vessel 13 and the second reaction vessel 14, to prevent the heating temperature of the heating component 12 from being too high.

[0054] Specifically, when the temperature sensor 16 detects that the temperature on the base 11 is high, the detection device 1 can reduce the input current to the heating component 12 to reduce the heat generated by the heating component 12. When the temperature sensor 16 detects that the temperature on the base 11 is low, the detection device 1 can increase the input current to the heating component 12 to increase the heat generated by the heating component 12. By monitoring the temperature of the base 11 by the temperature sensor 16, the heat generated by the heating component 12 can be regulated in real time, so that the samples in the first reaction vessel 13 and the second reaction vessel 14 are at the temperature required by the user, and the detection efficiency of the samples is improved.

[0055] In summary, in the detection device 1 provided by the embodiments of the present application, the first reaction container 13 and the second reaction container 14 are symmetrically arranged with respect to the central axis of the heating component 12, ensuring that the temperature transferred by the heating component 12 to the sample in the first reaction container 13 is equal to the temperature transferred by the heating component 12 to the sample in the second reaction container 14, enabling the samples in the first reaction container 13 and the second reaction container 14 to maintain a constant temperature at the same temperature, and improving the detection efficiency of the detection device 1 for the samples in the first reaction container 13 and the second reaction container 14.

[0056] Moreover, the first bearing portion 111 and the second bearing portion 112 of the base body 11 are symmetrically arranged with respect to the central axis of the heating component 12, further ensuring that the temperature transferred by the heating component 12 to the sample in the first reaction container 13 is equal to the temperature transferred by the heating component 12 to the sample in the second reaction container 14, and improving the heating efficiency of the heating component 12 for the samples in the first reaction container 13 and the second reaction container 14.

[0057] Meanwhile, the detection assembly 15 detects the sample in the first reaction container 13 through the first through hole 113 and detects the sample in the second reaction container 14 through the second through hole 114, avoiding the influence of the external environment on the detection assembly 15, further improving the detection efficiency of the detection device 1 for the sample, and improving the detection efficiency of the user for the detection device 1.

[0058] The present application also provides a sample analyzer (not shown in the figure), including a detection device 1 and a sample injection assembly. The detection device 1 and the sample injection assembly are arranged at intervals. The sample injection assembly is used to add blood samples into the first reaction container 13 and the second reaction container 14 of the detection device 1.

[0059] When the blood sample needs to be detected, the sample injection assembly moves to the detection device 1 and injects the sample into the first reaction container 13 and the second reaction container 14. The heating component 12 simultaneously heats the samples in the first reaction container 13 and the second reaction container 14, enabling the samples in the first reaction container 13 and the second reaction container 14 to be in a constant temperature state at the same temperature, facilitating the detection device 1 to detect the blood samples in the first reaction container 13 and the second reaction container 14, and improving the detection efficiency of the sample analyzer for the sample.

[0060] Optionally, the sample analyzer further includes a control component. The control component is connected to the heating component 12, and the control component is used to control the magnitude of the current input to the heating component 12 to adjust the heating temperature of the heating component 12.

[0061] Specifically, the control component can also be connected to the temperature sensor 16. Further, when the temperature sensor 16 detects that the temperature of the substrate 11 is relatively high, the control module receives a signal indicating a high temperature, and reduces the current input to the heating element 12, so as to reduce the heat generated by the heating element 12 and lower the heating temperature of the heating element 12. When the temperature sensor 16 detects that the temperature of the substrate 11 is relatively low, the control module receives a signal indicating a low temperature, and increases the current input to the heating element 12, so as to increase the heat generated by the heating element 12 and raise the heating temperature of the heating element 12. By controlling the magnitude of the current input to the heating element 12 by the control module, the heating temperature of the heating element 12 is adjusted, the adaptability of the heating element 12 to heat the sample is improved, and the detection efficiency of the sample analyzer for the sample is enhanced.

[0062] The above description is only the implementation mode of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
