DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] like Figure 1 As shown, the present embodiment provides a temperature calibration device dedicated to the novel coronavirus instant molecular diagnostic system, including a tube body 1, the tube body 1 having an internal cavity and its upper end is sealed, an upper partition 2 and a lower partition 3 are arranged from top to bottom in the tube body 1, thereby dividing the internal cavity into three mutually isolated spaces of upper, middle and lower layers, the upper, middle and lower spaces are respectively filled with a certain amount of standard liquid 4, the upper, middle and lower spaces are respectively provided with temperature sensors 5 and immersed in the corresponding standard liquid 4, the connecting wires 6 of the three temperature sensors 5 pass upward through the partition and the upper end of the tube body, are led out to the outside of the tube body 1 and are connected to a high-precision temperature collector 7.

[0022] Among them, the shape of the tube body 1 is adapted to the shape of the sample tube of the novel coronavirus instant molecular diagnosis system so as to adapt to the shape of the temperature control area of ​​the novel coronavirus instant molecular diagnosis system.

[0023] In order to meet the calibration test requirements, the standard liquid is a liquid with a boiling point higher than 100°C. In this embodiment, the standard liquid is silicone oil. It should be noted that when the standard liquid is filled in each layer of space, the standard liquid does not fill the entire space, and the filling amount of the standard liquid refers to the amount of the sample to be tested, thereby simulating the state of the sample when the device is actually used, so that the measured temperature is closer to the actual use situation.

[0024] In this embodiment, the temperature sensor is a thermocouple. It should be noted that before the device is used, the temperature sensor will be calibrated using a standard platinum resistor and a constant temperature bath to ensure the accuracy of its temperature.

[0025] like Figure 1As shown, in one embodiment of the utility model, the upper partition 2 and the lower partition 3 are non-detachable structures, which are fixedly connected to the side wall of the tube body 1 as a whole. The upper end 8 of the tube body 1 is fixedly connected to the side wall of the tube body 1 as a whole. The characteristics of this non-detachable structure are simple structure, which is manufactured as a whole during production, and is convenient to use and maintain in the later stage; but the disadvantage is that when calibrating the temperature sensor (thermocouple) in the device, the calibration cycle is long, and the entire device needs to be placed in a constant temperature bath, and the temperature sensor therein can be calibrated only after the temperature of the entire device is stable; moreover, the standard liquid cannot be replaced in this structure, and if the temperature sensor is damaged in the later stage, it is difficult to repair and replace.

[0026] like Figure 2 As shown, in another embodiment of the utility model, the upper partition 202 and the lower partition 203 are detachable structures, and the inner wall of the tube body 201 has inner flanges 11 corresponding to the installation positions of the upper and lower partitions, and the inner flanges 11 are provided with sealing rings 9, and the upper and lower partitions are respectively clamped on the corresponding inner flanges 11 through the sealing rings 9. The device also includes a pipe cover 10 with internal threads, and the outer wall of the upper end of the tube body 201 has external threads correspondingly. The pipe cover 10 is sealed and connected with the upper end of the tube body 201 to form the sealed upper end of the tube body. The characteristic of this detachable structure is that the temperature sensor (thermocouple) can be removed from the device for separate calibration, the calibration cycle of the temperature sensor is short, and if the temperature sensor is damaged, it can be repaired and replaced separately; the structure can also replace the standard liquid as needed. However, this structure also has some disadvantages, that is, the structure is more complicated and has higher requirements for users; and during use, the sealing of the sealing ring must be ensured, and the sealing ring needs to be replaced when necessary.

[0027] In this device, the temperature sensor can have a variety of fixed positions and fixing methods.

[0028] like Figure 1 As shown, in one embodiment, the temperature sensor 5 is fixed on the inner wall of the tube body 1, and its connecting wire 6 passes through the partition and the upper end of the tube body upwards and is led out of the tube body 1. It should be noted that the connecting wire passes through the position of the partition and the upper end of the tube body, and the connecting wire is sealed and fixedly connected to the partition and the upper end of the tube body.

[0029] like Figure 2As shown, in another embodiment, the device includes three vertically arranged hollow rigid tubes, wherein the lower end of the first hollow rigid tube 12 is located in the lower space, and it passes through the lower partition, the upper partition and the upper end of the tube body in sequence upwards and is led out of the tube body, the lower end of the second hollow rigid tube 13 is located in the middle space, and it passes through the upper partition and the upper end of the tube body in sequence upwards and is led out of the tube body, and the lower end of the third hollow rigid tube 14 is located in the upper space, and it passes through the upper end of the tube body in sequence upwards and is led out of the tube body. The connecting wires 6 of the three temperature sensors 5 are respectively arranged in the corresponding hollow rigid tubes, and the lower ends of the connecting wires pass through the hollow rigid tubes and the corresponding temperature sensors. It should be noted that the hollow rigid tube passes through the partition and the upper end of the tube body, and the hollow rigid tube is sealed and fixedly connected to the partition and the upper end of the tube body.

[0030] The working principle of the temperature calibration device for the novel coronavirus instant molecular diagnosis system of the utility model is as follows: put the device into the novel coronavirus instant molecular diagnosis system like a simulated sample test tube, and connect the connecting wire of the temperature sensor to a high-precision temperature collector. Then, start the novel coronavirus instant molecular diagnosis system to perform the diagnosis. During the operation of the system, compare the temperature index displayed by the system with the temperature data collected by the temperature collector, and realize the calibration detection of the temperature performance index of the novel coronavirus instant molecular diagnosis system through comparative calculation.

[0031] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
