[0008] In an embodiment of the present application, the calibration device also includes an elastic limiting component arranged in the calibration body, and the elastic limiting component and the position calibration part are respectively plugged into the opposite side walls of the calibration body. When the PCR analysis module pushes the position calibration part, the elastic limiting component is used to elastically limit the moving distance of the position calibration part.

[0009] In an embodiment of the present application, the elastic limiting component includes:

[0010] Block;

[0011] A limit post, one end of which is connected to the stopper, and the other end of which is spaced apart from the position calibration piece; and

[0012] The elastic member is arranged around the outer circumference of the limiting column and one end of the elastic member away from the stop block is elastically in contact with the position calibration member.

[0013] In an embodiment of the present application, a hollow cavity extending along the length direction is opened at one end of the position calibration member facing the elastic member, and the other end is closed, and the end of the elastic member facing away from the stop block is inserted into the hollow cavity.

[0014] In an embodiment of the present application, a sensing portion is provided at the bottom of the position calibration member, and a avoidance space for avoiding the sensing portion is opened in the first position detector.

At this time, the PCR analysis module pushes the position calibration part to move relative to the calibration body.

[0039] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0040] The calibration device according to the present application is described below with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 2 As shown, in an embodiment of the present application, a calibration device is proposed for calibrating a POCT all-in-one machine, the POCT all-in-one machine including a PCR analysis module, a pipetting and extraction module, and a heating module. Since the POCT all-in-one machine needs to calibrate the positions of the PCR analysis module and the pipetting and extraction module before leaving the factory and after being used for a period of time, and perform temperature calibration on the PCR analysis module, and perform temperature calibration on the heating module, based on the above background technology, the calibration device includes a calibration body 10, and the calibration body 10 is used to install various components for the calibration module, such as a position calibration mechanism for position calibration detection and a temperature calibration mechanism for temperature calibration detection.

[0042] Among them, the position calibration mechanism includes a position calibration part 21, a first position detector 22 and a second position detector 23. When the PCR analysis module pushes the position calibration part 21 to move relative to the calibration body 10, the first position detector 22 cooperates with the position calibration part 21 and detects the Y-axis coordinate of the PCR analysis module at the amplification position. When the pipetting and extraction module moves relative to the calibration body 10, the second position detector 23 can detect the Y-axis and Z-axis coordinates of the pipetting and extraction module at the extraction position.

[0043] When calibrating the amplification position of the PCR analysis module, the calibration device quickly moves to the vicinity of the PCR analysis module and then slowly approaches the PCR analysis module. At this time, the PCR analysis module pushes the position calibration component 21 to move relative to the calibration body 10. When the position calibration component 21 moves to the first position detector 22, it causes the position signal output of the first position detector 22 to obtain the Y-axis coordinate of the current amplification position. By adding the compensation value, the calibration of the PCR analysis module at the amplification position can be completed.

[0044] When the calibration device retreats to the vicinity of the pipetting extraction position, the pipetting pump of the pipetting extraction module descends to a predetermined position. During the movement of the calibration device in the left and right directions, the tip of the pipetting pump will pass through the second position detector 23. At this time, the second position detector 23 generates two signal changes, and obtains two Y-axis coordinates. By taking the middle value and then adding a compensation value (this value is fixed and defined by the distance between the theoretical extraction position and the actual calibration extraction position), the accurate Y position of the pipetting extraction can be calculated to complete the Y-axis coordinate calibration at the extraction position. At the pipetting extraction position, the pipetting pump moves upward, and when the second position detector 23 generates a signal change, the current Z-axis coordinate is obtained. After adding a compensation value, the calibration of the Z coordinate of the pipetting extraction position is completed. Among them, the Y axis refers to Figure 1 The left and right directions in the Z axis refer to Figure 1 The up and down directions in .

[0045] Furthermore, the temperature calibration mechanism includes a first temperature detection component 31 and a second temperature detection component 32. The first temperature detection component 31 is installed on the side wall of the calibration body 10 and is used to detect the temperature of the PCR analysis module. The second temperature detection component 32 is installed on the bottom of the calibration body 10 and is used to detect the heating temperature of the heating module.

[0046] In summary, under the premise of ensuring that the POCT all-in-one machine is not disassembled, the present application integrates the position calibration and temperature calibration into the calibration body 10, and adjusts and calibrates the working position and temperature performance of the POCT all-in-one machine, specifically including the adjustment of the amplification position, extraction position, and temperature performance. The overall calibration device structure is more compact, which improves the calibration efficiency of the POCT all-in-one machine.

[0047] In an embodiment of the present application, the calibration device also includes an elastic limiting component 40 arranged in the calibration body 10, and the elastic limiting component 40 and the position calibration component 21 are respectively plugged into the opposite side walls of the calibration body 10, that is, the elastic limiting component 40 and the position calibration component 21 are maintained in a straight line on the left and right, and the end of the position calibration component 21 facing away from the elastic limiting component 40 protrudes from the side wall of the calibration body 10, and the left and right sliding of the position calibration component 21 is achieved by squeezing or detaching the PCR analysis module. When the PCR analysis module pushes the position calibration component 21, the elastic limiting component 40 is used to elastically limit the moving distance of the position calibration component 21.

[0048] like Figures 2 to 3 As shown, the elastic limit assembly 40 includes a stop block 41, a limit column 42 and an elastic member 43; one end of the limit column 42 is connected to the stop block 41, and the other end is spaced apart from the position calibration member 21; the elastic member 43 is arranged around the outer periphery of the limit column 42 and the end away from the stop block 41 is elastically abutted against the position calibration member 21.

[0049] When calibrating the amplification position of the PCR analysis module, the elastic member 43 extends in the left-right direction and is elastically connected to the position calibration member 21, so that a moving force can be provided to the position calibration member 21. The limit column 42 is fixed to the stopper 41 by screws, which can reduce the difficulty of processing and is also easy to replace. The elastic member 43 is sleeved on the limit column 42, so that the limit column 42 can provide a radial constraint to the elastic member 43. Whether in the assembly process or the movement process, the elastic member 43 will be in a relatively stable state. When not in contact with the PCR analysis module, the limit column 42 maintains a certain distance from the end of the position calibration member 21. When the PCR analysis module pushes the position calibration member 21, the position calibration member 21 moves slowly to the left under the buffering effect of the elastic member 43 until the position calibration member 21 contacts the limit column 42, thereby stopping the movement. That is to say, the limit column 42 acts on the position calibration member 21 to limit the distance of the position calibration member 21 to the left.

[0050] like Figure 2 As shown, the position calibration member 21 has a hollow cavity 211 extending in the length direction at one end facing the elastic member 43, and the other end is closed, and the end of the elastic member 43 away from the stopper 41 is inserted into the hollow cavity 211. Under the limiting action of the limiting column 42, the elastic member 43 can be ensured to always extend in the left-right direction, and the right end of the elastic member 43 is inserted into the hollow cavity 211, so that the position calibration member 21 always maintains a state of being connected to the elastic member 43, ensuring the stability of the position calibration member 21 during the movement in the left-right direction.

[0051] In the embodiment of the present application, the bottom of the position calibration member 21 is provided with a sensing portion 212, and the first position detector 22 is provided with an escape space for evading the sensing portion 212. When the position calibration member 21 is sliding, the sensing portion 212 can pass through the escape space. When calibrating the amplification position of the PCR analysis module, the entire calibration device is quickly moved to the vicinity of the position of the PCR analysis module, and then slowly moved closer. When the PCR analysis module touches the position calibration member 21, the entire position calibration member 21 slides toward the limit column 42 under the external force of the PCR analysis module. During the sliding process, the sensing portion 212 also slides simultaneously. When the sensing portion 212 slides to the escape space on the first position detector 22, the first position detector 22 can detect the signal of the position calibration member 21 and output the signal, so as to obtain the Y coordinate of the current PCR analysis module. At this time, by adding the pre-set compensation value, the position calibration detection of the PCR analysis module can be completed.

[0052] Among them, the position calibration part 21 is made of brass. Since brass is light and easy to insert and slide along the left and right directions, and the surface of the brass material does not require special treatment, it is more convenient to use. In addition, brass has good sliding performance, which is conducive to the left and right sliding of the sensing part 212 under the squeezing and pushing of the PCR analysis module.

[0053] like Figure 1 As shown, a receiving groove matching the shape of the second position detector 23 is provided at the top of the calibration body 10, and the second position detector 23 is embedded in the receiving groove. The upper top surface of the second position detector 23 is flush with the entire calibration body 10 and does not protrude from the calibration body 10, so that the second position detector 23 can be prevented from being exposed outside the calibration body 10, and the structure of the entire calibration device is more complete and beautiful from the appearance.

[0054] In an embodiment of the present application, the first temperature detection component 31 includes a detection probe and a first temperature detector arranged in the detection probe. The side wall of the calibration body 10 is provided with a temperature detection cavity. The detection probe is accommodated in the temperature detection cavity and the detection end extends out of the calibration body 10.

[0055] Among them, the detection probe includes a mounting base and a flat tube inserted into the mounting base. In the present application, the mounting base is installed in the temperature detection cavity, and the temperature measuring end of the flat tube extends from the temperature detection cavity. When the temperature measuring end is inserted into the PCR analysis module, the heat of the PCR analysis module is transferred to the first temperature detector through the heat conduction effect of the flat tube, so that the first temperature detector can transmit the temperature signal of the PCR analysis module, thereby realizing temperature detection of the PCR analysis module.

[0056] In an embodiment of the present application, the second temperature detection member 32 includes a heat conducting portion 321, a second temperature detector and a heat insulating plate 322. The second temperature detector is arranged in the heat conducting portion 321. One end of the heat conducting portion 321 passes through the heat insulating plate 322 and is inserted into the calibration body 10. During the temperature detection process, the heat conducting portion 321 contacts the heating module, and the heat of the heating module is transferred to the internal second temperature detector through the heat conducting portion 321. The second temperature detector can sense the temperature signal and transmit it, thereby realizing the temperature detection of the heating module. In order to prevent the calibration body 10 from being damaged due to the excessive temperature of the heat conducting portion 321 and direct contact with the calibration body 10 during the temperature detection process, a heat insulating plate 322 is provided on the side of the heat conducting portion 321 facing the calibration body 10. The setting of the heat insulating plate 322 can block the heat of the heat conducting portion 321 from being transferred to the calibration body 10, so as to protect the calibration body 10.

[0057] In the embodiment of the present application, a first cable cover 323 is further provided on the periphery of the heat insulation board 322, and the first cable cover 323 and the calibration body 10 cooperate to wrap the periphery of the heat insulation board 322 and the heat conducting part 321 to protect the heat insulation board 322 and the heat conducting part 321, thereby improving the service life of the entire second temperature detection member 32. In addition, a second cable cover 80 is further provided on the periphery of the second temperature detection member 32 to prevent the second temperature detection member 32 from frequently contacting the calibration body 10 during use and shortening the service life, and the cable of the second temperature detector can be electrically connected to the circuit control board 50 in the calibration body 10 via the first cable cover 323 and the second cable cover 80 to achieve normal transmission of the temperature detection signal.

[0058] Furthermore, if Figure 4 As shown, the calibration body 10 has a receiving cavity 11, and the calibration device also includes a circuit control board 50 disposed in the receiving cavity 11. Since the circuit control board 50 is arranged with various electronic components required for calibration, considering the limitation of space, two layers of circuit boards are stacked to handle it, so that the required control components can be arranged in a small space, which fully saves space. In addition, a cover 60 is covered above the circuit control board 50. The cover 60 cooperates with the calibration body 10 to seal the circuit control board 50 in the receiving cavity 11. On the one hand, it can protect the circuit control board 50 and prevent the electronic components on the circuit control board 50 from being exposed to the outside. On the other hand, it improves the entire structure and makes the overall calibration mechanism more complete. In addition, a wire clamp 70 for collecting the circuit is also provided on the outside of the entire calibration body 10.

[0059] In order to realize the automation of calibration, the first position detector 22, the second position detector 23, the first temperature detector and the second temperature detector are all photoelectric sensors and electrically connected to the circuit control board 50, so that the entire circuit control board 50 controls the operation of the first position detector 22, the second position detector 23, the first temperature detector and the second temperature detector, with higher accuracy and convenient operation, thereby improving the client's experience.
