Abstract
Description
Technical Field
[0001] This application relates to the technical field of electrophoresis instruments, and particularly to a precision nucleic acid electrophoresis instrument capable of wirelessly transmitting data. Background Art
[0002] An electrophoresis instrument is an instrument for realizing electrophoresis analysis. Generally composed of a power supply, an electrophoresis tank, a detection unit, etc., it can enable charged particles to move in an electric field. Based on the different movement speeds of different substances in the electric field, qualitative and quantitative analysis of different substances can be achieved, or component analysis or single-component extraction of a certain mixture can be carried out.
[0003] In the prior art, there is a precision nucleic acid electrophoresis instrument capable of wirelessly transmitting data, which includes an electrophoresis box and a cover plate. The cover plate is rotatably connected to the electrophoresis box. An electrophoresis tank is provided on the top wall of the electrophoresis box, and an electrophoresis buffer solution is provided in the electrophoresis tank for nucleic acid electrophoresis. Electric connection plates are provided on both inner side walls of the electrophoresis tank along its length direction. A power supply and a control mechanism are also provided on the electrophoresis box. The power supply is used to energize the electric connection plates, and the circuit connected between the power supply and the electric connection plates is controlled by the control mechanism. The control mechanism is used to control the voltage supplied by the power supply to the electric connection plates and the duration of energizing the electric connection plates. The control mechanism is also used to detect and record relevant data during electrophoresis, and wirelessly transmit the recorded data to other data processing devices. When in use, first place the prepared agarose gel and the gel-making plate together in the electrophoresis tank, then load the sample into the sample wells on the gel with a pipette, then cover the cover plate, and connect the power supply and the electric connection plates through the control mechanism for analysis.
[0004] In view of the above related technologies, when it is necessary to conduct experimental detection on nucleic acids with relatively large molecular weights, usually the methods of increasing the voltage and prolonging the electrophoresis time are adopted to obtain better and more obvious data. However, too high a voltage and long-term power-on will cause the temperature of the electrophoresis buffer solution to rise, resulting in excessive local heating of the agarose gel, which is likely to cause local melting of the agarose gel, thereby being unfavorable for the movement of nucleic acid molecules and reducing the efficiency of the experiment. Summary of the Utility Model
[0005] In order to reduce the probability of local melting of the agarose gel, this application provides a precision nucleic acid electrophoresis instrument capable of wirelessly transmitting data.
[0006] A precision nucleic acid electrophoresis instrument capable of wirelessly transmitting data provided by this application adopts the following technical solutions:
[0007] A precision nucleic acid electrophoresis instrument capable of wirelessly transmitting data, comprising an electrophoresis box and a cover body. An electrophoresis tank is provided on the top wall of the electrophoresis box. Two electric connection plates are further provided on the opposite inner side walls of the electrophoresis tank. A control mechanism is arranged inside the electrophoresis box. The control mechanism includes a temperature detection component and a control component. A refrigeration mechanism is also arranged on the electrophoresis box. The temperature detection component and the refrigeration mechanism are both controlled by the control component. The temperature detection component is used to detect the temperature value of the electrophoresis buffer solution in the electrophoresis tank. The control component is used to control the opening and closing of the refrigeration mechanism based on the detected temperature value. The refrigeration mechanism is used to refrigerate the electrophoresis buffer solution in the electrophoresis tank.
[0008] By adopting the above technical solution, compared with the prior art, in which too high voltage and long-time power-on will cause the temperature of the electrophoresis buffer solution to rise, resulting in local melting of the agarose gel. In this application, by setting the control mechanism and the refrigeration mechanism, the temperature detection component can detect the temperature value of the electrophoresis buffer solution in the electrophoresis tank. Thus, when the temperature value of the electrophoresis buffer solution in the electrophoresis tank is too high, the refrigeration mechanism can be controlled to refrigerate the electrophoresis buffer solution, reducing the temperature of the electrophoresis buffer solution and keeping the temperature of the electrophoresis buffer solution at an appropriate value. Therefore, on the basis of ensuring that the voltage required for the experiment does not decrease, the probability of local melting of the agarose gel due to excessive heating and temperature rise is reduced, effectively ensuring the normal movement of nucleic acid molecules, ensuring the efficiency of the experiment, and at the same time effectively ensuring the accuracy of the final test data.
[0009] Preferably, the refrigeration mechanism includes a liquid storage tank, a refrigerator, a cooling pipe, and a micro water pump. The liquid storage tank stores a coolant. The refrigerator is used to cool the coolant in the liquid storage tank. One end of the cooling pipe is communicated with the liquid storage tank. The other end of the cooling pipe extends into the electrophoresis tank, passes through the electrophoresis tank, and finally communicates with the liquid storage tank. The micro water pump is arranged on the cooling pipe. The micro water pump is electrically connected to the control component. The control component is used to control the opening and closing of the micro water pump.
[0010] By adopting the above technical solution, with the specific setting of the refrigeration mechanism, the control component can control the opening and closing of the micro water pump based on the temperature value detected by the temperature detection component. Thus, when the detected temperature value is too large, the control component can control the micro water pump to open, thereby pumping the coolant in the liquid storage tank into the cooling pipe. The coolant cools the cooling pipe through heat exchange, and the cooling pipe cools the electrophoresis buffer solution in the electrophoresis tank through heat exchange, ensuring that the temperature of the electrophoresis buffer solution is kept at an appropriate value and ensuring the cooling effect on the electrophoresis buffer solution.
[0011] Preferably, the liquid storage tank is slidably connected to the electrophoresis box. A locking component is also arranged on the electrophoresis box. The locking component is used to lock the liquid storage tank and the electrophoresis box.
[0012] By adopting the above technical solution, the sliding connection between the liquid storage tank and the electrophoresis box enables the experimenter to remove and replace the liquid storage tank by sliding it out, thus facilitating the replacement of the liquid storage tank by the experimenter. At the same time, the presence of the locking component also enables the experimenter to lock the liquid storage tank through the locking component after the liquid storage tank is installed in the electrophoresis box, thereby reducing the probability of the liquid storage tank slipping out.
[0013] Preferably, the locking component includes a locking frame and an elastic member. The locking frame is slidably connected to the electrophoresis box. The sliding direction of the locking frame is perpendicular to the sliding direction of the liquid storage tank. One end of the locking frame is inserted into the side wall of the liquid storage tank, and the elastic member is used to keep the locking frame inserted into the side wall of the liquid storage tank.
[0014] By adopting the above technical solution, the specific setting of the locking component enables the locking frame to be continuously inserted into the side wall of the liquid storage tank under the elastic force of the elastic member, thereby realizing the locking of the liquid storage tank. At the same time, the presence of the elastic member enables the locking frame to maintain the state of being inserted into the liquid storage tank, thus ensuring the locking effect on the liquid storage tank.
[0015] Preferably, the end of the locking frame away from the liquid storage tank extends out of the electrophoresis box.
[0016] By adopting the above technical solution, the setting that one end of the locking frame extends out of the liquid storage tank enables the experimenter to pull the end of the locking frame extending out of the liquid storage tank, so that the locking frame overcomes the elastic force of the elastic member, and thus the locking frame completely disengages from the outside of the liquid storage tank to realize the unlocking of the liquid storage tank, effectively facilitating the operation of the experimenter.
[0017] Preferably, an arc-shaped guiding surface is further provided on the locking frame along its sliding direction and close to the liquid storage tank.
[0018] By adopting the above technical solution, the setting of the arc-shaped guiding surface enables the end of the liquid storage tank to gradually abut against the arc-shaped guiding surface on the locking frame during the process of the liquid storage tank sliding into the electrophoresis box, thereby pushing the locking frame to slide in a direction away from the liquid storage tank, enabling the locking frame to overcome the elastic force of the elastic member, realizing the avoidance of the liquid storage tank, and enabling the liquid storage tank to slide in normally.
[0019] Preferably, the refrigeration mechanism further includes a mounting plate. The mounting plate is arranged in the electrophoresis tank. The cooling pipe includes a main body part and two hose parts. The main body part is mounted on the mounting plate. Both ends of the main body part extend out of the electrophoresis tank. One end of each of the two hose parts is communicated with both ends of the main body part respectively, and the other end of each hose part is communicated with the liquid storage tank.
[0020] By adopting the above technical solution, the specific setting of the cooling pipe enables the main body of the cooling pipe to be installed in the electrophoresis tank along with the mounting plate, and the flexible hose part of the cooling pipe can be communicated with the liquid storage tank. As a result, the experimenter can disassemble the end of the flexible hose part from the liquid storage tank and then replace the liquid storage tank, effectively facilitating the replacement of the liquid storage tank by the experimenter.
[0021] Preferably, the bottom end of the mounting plate is embedded in the inner bottom wall of the electrophoresis tank and is detachably connected to the inner bottom wall of the electrophoresis tank.
[0022] By adopting the above technical solution, the detachable connection between the mounting plate and the inner bottom wall of the electrophoresis tank enables the experimenter to detach the main body of the cooling pipe uniformly through the dismounting plate, thus facilitating the disassembly and replacement of the main body of the cooling pipe by the experimenter.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The setting of the control mechanism and the refrigeration mechanism enables the temperature detection component to detect the temperature value of the electrophoresis buffer solution in the electrophoresis tank. Therefore, when the temperature value of the electrophoresis buffer solution in the electrophoresis tank is too high, the refrigeration mechanism can be controlled to refrigerate the electrophoresis buffer solution, reducing the temperature of the electrophoresis buffer solution so that the temperature of the electrophoresis buffer solution can be maintained at an appropriate value. Thus, on the basis of ensuring that the required voltage for the experiment does not decrease, the probability of local melting of the agarose gel due to excessive heating is reduced, effectively ensuring the normal movement of nucleic acid molecules, ensuring the efficiency of the experiment, and at the same time effectively ensuring the accuracy of the final test data;
[0025] 2. The specific setting of the refrigeration mechanism enables the control component to control the opening and closing of the micro water pump based on the temperature value detected by the temperature detection component. Therefore, when the detected temperature value is too large, the control component can control the micro water pump to open, thereby pumping the coolant in the liquid storage tank into the cooling pipe. The coolant cools the cooling pipe through heat exchange, and the cooling pipe cools the electrophoresis buffer solution in the electrophoresis tank through heat exchange, thus ensuring that the temperature of the electrophoresis buffer solution is maintained at an appropriate value and ensuring the cooling effect on the electrophoresis buffer solution;
[0026] 3. The setting of the sliding connection between the liquid storage tank and the electrophoresis box enables the experimenter to slide out the liquid storage tank to achieve the disassembly and replacement of the liquid storage tank, thus facilitating the replacement of the liquid storage tank by the experimenter. At the same time, the presence of the locking component also enables the experimenter to lock the liquid storage tank through the locking component after the liquid storage tank is installed in the electrophoresis box, thereby reducing the probability of the liquid storage tank coming out.

[0032] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.
[0033] An embodiment of the present application discloses a precision nucleic acid electrophoresis instrument capable of wirelessly transmitting data. Referring to Figure 1 , the precision nucleic acid electrophoresis instrument capable of wirelessly transmitting data includes an electrophoresis box 1 and a cover body 2. An electrophoresis tank 11 is provided on the top wall of the electrophoresis box 1, and two electrical connection plates 3 are further provided on the opposite inner side walls of the electrophoresis tank 11.

A refrigeration mechanism 5 is also provided on the electrophoresis box 1. Both the temperature detection element 41 and the refrigeration mechanism 5 are controlled by the control element 42. The temperature detection element 41 is used to detect the temperature value of the electrophoresis buffer solution in the electrophoresis tank 11, and the control element 42 is used to control the opening and closing of the refrigeration mechanism 5 based on the detected temperature value. The refrigeration mechanism 5 is used to refrigerate the electrophoresis buffer solution in the electrophoresis tank 11.
[0034] Referring to Figure 1 , one end of the cover body 2 and one side of the electrophoresis box 1 along its width direction are rotatably connected through a pin shaft. Buffer tanks 12 are provided at both ends of the top wall of the electrophoresis box 1 along its length direction. Each buffer tank 12 communicates with the electrophoresis tank 11, and the bottom end of each buffer tank 12 is lower than the bottom end of the electrophoresis tank 11. The electrical connection plates 3 correspond to the buffer tanks 12, and the bottom end of each electrical connection plate 3 extends into the corresponding buffer tank 12. Each electrical connection plate 3 is electrically connected to the power supply inside the electrophoresis box 1 through a circuit.
[0035] Reference Figure 1 、 Figure 2 and Figure 3 , the refrigeration mechanism 5 includes a liquid storage tank 51, a refrigerator 52, a cooling pipe 53 and a micro water pump 54. The liquid storage tank 51 stores a coolant. The liquid storage tank 51 is slidably connected to the electrophoresis box 1 through a slide rail. The sliding direction of the liquid storage tank 51 is the width direction of the electrophoresis box 1. On the inner side wall of the electrophoresis box 1 along its width direction, a sliding groove 13 for the electrophoresis box 1 to slide is also penetrated and opened.
[0036] Reference Figure 1 and Figure 4 , a locking assembly 6 is further provided on the electrophoresis box 1. The locking assembly 6 is located on one side of the electrophoresis box 1 along its width direction. The locking assembly 6 includes a locking frame 61 and an elastic member 62. The locking frame 61 is slidably connected to the electrophoresis box 1. The sliding direction of the locking frame 61 is the length direction of the electrophoresis box 1, so that the sliding direction of the locking frame 61 is perpendicular to the sliding direction of the liquid storage tank 51.
[0037] Reference Figure 1 and Figure 4 , one end of the locking frame 61 along its sliding direction and close to the liquid storage tank 51 is inserted into the side wall of the liquid storage tank 51 to lock the liquid storage tank 51. An arc-shaped guiding surface is also opened on one end of the locking frame 61 inserted into the liquid storage tank 51, so that during the process of the liquid storage tank 51 sliding into the electrophoresis box 1, the end of the liquid storage tank 51 can abut against the arc-shaped guiding surface, so that the locking frame 61 slides away from the liquid storage tank 51 to realize the avoidance of the liquid storage tank 51.
[0038] Reference Figure 1 and Figure 4 , at the other end of the locking frame 61 along its sliding direction, a pulling-out portion 611 is further extended. The cross-sectional area of the pulling-out portion 611 is smaller than the cross-sectional area of the other positions of the locking frame 61. The pulling-out portion 611 extends out of the electrophoresis box 1 for the experimenter to pull the locking frame 61. In the embodiment of the present application, the elastic member 62 is set as a compression spring. The spring is sleeved on the pulling-out portion 611, and one end of the compression spring abuts against one end of the locking frame 61 close to the pulling-out portion 611, and the other end of the compression spring abuts against the inner wall of the electrophoresis box 1.
[0039] Reference Figure 1 and Figure 4 , in the initial state, the end of the pulling-out portion 611 extending out of the electrophoresis box 1 abuts against the outer wall of the electrophoresis box 1. At this time, the compression spring is still in a compressed state to apply an elastic force to the locking frame 61. When it is necessary to unlock the liquid storage tank 51, pull the pulling-out portion 611, so that the locking frame 61 slides away from the liquid storage tank 51, so that the locking frame 61 completely slides out of the liquid storage tank 51 to realize the unlocking of the liquid storage tank 51, so as to facilitate the experimenter to slide the liquid storage tank 51 out of the electrophoresis box 1.
[0040] Referring to Figure 1 and Figure 2 , the cooler 52 is fixedly installed on the liquid storage tank 51 along the width direction of the electrophoresis cassette 1 and near one end of the locking assembly 6. The cooler 52 is used to cool the coolant in the liquid storage tank 51. The micro water pump 54 is fixedly installed on the liquid storage tank 51 by bolts, and is located on the side of the liquid storage tank 51 away from the cooler 52 and at the bottom of the liquid storage tank 51. One end of the micro water pump 54 is communicated with the chamber in the liquid storage tank 51 through a pipeline for pumping out the coolant in the liquid storage tank 51.
[0041] Referring to Figure 2 and Figure 3 , at the top of the end of the liquid storage tank 51 away from the cooler 52, a pipeline also extends outward. This pipeline is communicated with the chamber in the liquid storage tank 51. The cooling pipe 53 includes a main body portion 531 and two hose portions 532. One hose portion 532 is sleeved on the other end of the micro water pump 54 and is communicated with the micro water pump 54. The other hose portion 532 is sleeved on the pipeline extending outward from the liquid storage tank 51 and is communicated with the liquid storage tank 51 to facilitate the disassembly of the liquid storage tank 51.
[0042] Referring to Figure 2 and Figure 3 , an installation plate 7 is further provided in the electrophoresis tank 11. The installation plate 7 is embedded in the inner bottom wall of the electrophoresis tank 11 and is detachably connected to the inner bottom wall of the electrophoresis tank 11 by screws. One end of the main body portion 531 is located below one side of the installation plate 7 along its own width direction. The other end of the main body portion 531 extends vertically upward to the top of the installation plate 7, is serpentinely arranged, and extends to the other side of the installation plate 7 along its own width direction, and finally extends vertically downward to below the installation plate 7. The main body portion 531 and the installation plate 7 are integrally formed.
[0043] Referring to Figure 2 and Figure 3 , two communication holes 14 are also penetrated and opened on the inner bottom wall of the electrophoresis tank 11. The communication holes 14 correspond to the two ends of the main body portion 531 one by one. Each end of the main body portion 531 is inserted into the corresponding communication hole 14, and the outer wall of the end portion of the main body portion 531 is in contact with the inner side wall of the communication hole 14. Two communication pipes 8 are further provided on the bottom end of the electrophoresis cassette 1. The communication pipes 8 are integrally formed with the electrophoresis cassette 1. The communication pipes 8 correspond to the communication holes 14 one by one and are located directly below the corresponding communication holes 14. The top end of each communication pipe 8 is communicated with the corresponding communication hole 14. The hose portions 532 are provided corresponding to the communication pipes 8 one by one. One end of each hose portion 532 away from the liquid storage tank 51 is sleeved on the corresponding communication pipe 8 so that the main body portion 531 is communicated with the chamber in the liquid storage tank 51 through the hose portions 532.
[0044] Referring to Figure 1, in the embodiment of the present application, the temperature detection element 41 is set as a temperature sensor, and the control element 42 is set as a PLC controller. The PLC controller is fixedly installed on the outer wall of the electrophoresis box 1. The temperature detection element 41 and the micro water pump 54 are both electrically connected to the control element 42, and the temperature detection element 41 is fixedly installed on the inner bottom wall of the electrophoresis tank 11. The temperature detection element 41 is used to detect the temperature value of the electrophoresis buffer solution in the electrophoresis tank 11 and feedback the temperature value to the control element 42.
[0045] Refer to Figure 1 , Figure 2 and Figure 3 , a preset value is pre-stored in the control element 42, and this preset value is the maximum temperature of the electrophoresis buffer solution. The control element 42 is used to receive the temperature value detected by the temperature detection element 41 and to compare this temperature value with the preset value. When this temperature value is greater than or equal to the preset value, the control element 42 controls the micro water pump 54 to start, and the coolant in the liquid storage tank 51 is introduced into the main body part 531 through the hose part 532, the connecting pipe 8, and the communication hole 14, and the electrophoresis buffer solution is cooled by heat transfer. Otherwise, the micro water pump 54 is kept closed.
[0046] The implementation principle of a precision nucleic acid electrophoresis instrument capable of wirelessly transmitting data in the embodiment of the present application is as follows: during use, when the temperature detection element 41 detects that the temperature of the electrophoresis buffer solution is too high, the control element 42 controls the micro water pump 54 and the cooler 52 to start, and the coolant in the liquid storage tank 51 is introduced into the main body part 531 through the hose part 532, the connecting pipe 8, and the communication hole 14, and the electrophoresis buffer solution is cooled by heat transfer. The cooled coolant after heat transfer then flows back to the chamber of the liquid storage tank 51 through the communication hole 14, the connecting pipe 8, and the hose part 532 and is cooled under the action of the cooler 52.
[0047] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
