Description

Technical Field

[0001] The present disclosure relates to the technical field of intelligent detection equipment, and in particular to a micro POCT detection equipment. Background Art

[0002] Currently, molecular POCT (point-of-care testing) equipment is widely developed and used because of its miniaturization, convenience, rapidity, integration and closedness.

[0003] Chinese patent application (CN 219991588 U) discloses a handheld nucleic acid detection device, which includes a main body, which is used for a user to hold; the main body is provided with an installation cavity for accommodating a carrier module, the carrier module is used for accommodating a reaction tube, and the reaction tube is used for accommodating an object to be detected; the carrier module is connected to a heating module, and the heating module is used to adjust the temperature of the carrier module to adjust the temperature of the reaction tube to a first temperature; the main body is connected to an excitation light module, the excitation light module is arranged at the bottom of the carrier module, and the carrier module is provided with an excitation light inlet toward the excitation light module, so that the excitation light signal of the excitation light module is irradiated on the reaction tube through the excitation light inlet; the main body is also provided with a signal acquisition module, and the signal acquisition module is used to collect the fluorescence signal of the reaction tube in real time under the irradiation of the excitation light signal and send it to the mobile terminal to obtain the detection result. In this patent application, the heating module is arranged on one side of the carrier module to heat the lower half of the heating tube in the carrier module.

[0004] However, in actual experiments, we found that under high temperature conditions (65°C or higher), since the lower half of the reaction tube is heated by a heating module and the upper half is exposed to the instrument space, the temperature of the lower half of the reaction tube is much higher than that of the upper half, dividing the entire reaction tube into two temperature zones, which in turn causes water vapor condensation on the top of the reaction tube.

[0005] In a precise, small-volume reaction system, even in a short-term experiment (temperature less than 70°C, reaction system greater than 20ul), water vapor condensation will have a certain impact on the experimental results. If the reaction temperature exceeds 90°C, the reaction evaporation will be more serious. If no control measures are taken, the evaporation will be too large, causing the water vapor to gather at the top and condense into small droplets, which eventually slide into the reaction system, causing errors in the experimental results. Generally, technicians will use non-instrumental means to assist, such as adding liquid paraffin to seal the liquid surface to solve this problem, but this also makes the experimental operation cumbersome.

DETAILED DESCRIPTION

[0032] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0033] According to one embodiment of the present disclosure, Figure 1-5 As shown, the utility model provides a micro POCT detection device, including a control module 1, a shell 2 and a top cover 3, the shell 2 is used to accommodate a reaction tube 4, the reaction tube 4 has a reaction tube cover 41, and a top cover heating module 5 is provided in the top cover 3, and the top cover heating module 5 is configured to be able to contact with the reaction tube cover 41 when the shell 2 and the top cover 3 are covered, and can heat the reaction tube cover 41 when in contact.

[0034] In the present application, the reaction tube 4 includes a reaction tube body and a reaction tube cover 41, and the reaction tube cover 41 is used to seal the reaction tube body to isolate the internal and external media; the top cover 3 and the shell 2 are both open cavity structures, and a top cover heating module 5 is added in the top cover 3. When the shell 2 and the top cover 3 are covered, the top cover heating module 5 can contact with the reaction tube cover 41 and heat the reaction tube cover 41. Thus, the temperature of the upper half of the reaction tube 4 can be adjusted, and when the lower half of the reaction tube 4 is heated by the heating module for reaction, when the water vapor evaporated in the reaction tube 4 rises to the reaction tube cover 41, because the temperature of the reaction tube cover 41 is slightly different from the reaction temperature of the reaction tube 4, the water vapor will not be pre-cooled and condensed on the reaction tube cover 41, thereby improving the precision and accuracy of the equipment during the experiment as a whole.

[0035] For example, although the top cover heating module 5 is in contact with the reaction tube cover 41 and directly heats the reaction tube cover 41, due to thermal conductivity, when the reaction tube cover 41 is heated, the heat can diffuse downward from the reaction tube cover 41 to the entire upper half of the reaction tube. Therefore, we can set the heating temperature of the reaction tube cover 41 by the top cover heating module 5 to be slightly higher than the reaction temperature of the reaction tube 4, which prevents water vapor from condensing at the reaction tube cover 41, thereby eliminating errors in the experiment.

[0036] Furthermore, since the top cover heating module 5 heats the reaction tube cover 41 alone, the heating temperature of the reaction tube cover 41 can be set to be consistent or close to the reaction temperature of the reaction tube 4, so that the entire reaction tube is in a temperature-uniform experimental parameter, thereby improving the precision and accuracy of the experiment.

[0037] In one embodiment, a micro POCT detection device of the present application also includes a pin connector, which is connected to the top cover heating module 5 and the control module 1. The pin connector is configured to conduct the connection between the control module 1 and the top cover heating module 5 when the top cover 3 is in a closed state, and to disconnect the connection between the control module 1 and the top cover heating module 5 when the top cover 3 is in an open state; wherein when the control module 1 and the top cover heating module 5 are conducted, the control module 1 controls whether the top cover heating module 5 is heated.

[0038] In one embodiment, Figure 1-5 As shown, the top cover heating module 5 is configured to form a downward elastic pressing force on the reaction tube 4 when the shell 2 and the top cover 3 are covered, and the reaction tube cover 41 can be heated during the pressing. When the shell 2 and the top cover 3 are in the covered state, the top cover heating module 5 is configured to form a downward elastic pressing force on the reaction tube 4, which can not only further press and fix the reaction tube 4, but also make the top cover heating module 5 and the reaction tube cover 41 in close contact, ensuring that the heat generated by the top cover heating module 5 can be effectively conducted to the reaction tube cover 41. In addition, since the top cover heating module 5 is elastically pressed on the reaction tube cover 41, the top cover heating module 5 can be adaptively adjusted for reaction tubes 4 of different heights.

[0039] For example, the top cover heating module 5 includes a heating plate assembly 51, which is installed in the top cover 3 through an elastic member 9, and is connected to the control module 1 through an ejector connector; the heating plate assembly 51 is configured to form a downward elastic pressing force on the reaction tube cover 41 when the housing 2 and the top cover 3 are closed, and the control module 1 can control whether to heat the reaction tube cover 41 during pressing. Therefore, the present application can achieve heating and temperature control of the heating tube cover 41 by setting an ejector connector and a top cover heating module. It is simple, convenient, and has high experimental accuracy.

[0040] Further, the heating plate assembly 51 includes a heating plate 511 and a heat conducting plate 512, the heating plate 511 is fixedly arranged on the heat conducting plate 512, and the heating plate 511 is connected to the control module through a pin connector, and the control module controls whether to heat. The heat conducting plate 512 is arranged outside the heating plate 511, and the heat conducting plate 512 is connected to the top cover 3 through an elastic member 9, so that when the elastic member 9 is compressed, the heating plate 511 moves together with the heat conducting plate 512. The heat conducting plate 512 is configured to form a downward elastic pressing force on the reaction tube cover 41 when the housing 2 and the top cover 3 are covered, and can conduct heat to the reaction tube cover 41 when the heating plate 511 is heated.

[0041] Furthermore, the top cover heating module 5 also includes a fastening plate 52, which is arranged on the outside of the heating plate 511 and fixedly connected to the heat conducting plate 512, so as to clamp the heating plate therebetween.

[0042] Among them, since the heat conducting plate 512 is connected to the top cover 3 through the elastic member 9, the elastic member 9 can be a spring. Therefore, when the top cover 3 is in the closed state, since the reaction tube 4 is accommodated in the shell, the reaction tube 4 is restricted from moving in the vertical direction. Therefore, when the reaction tube cover 41 presses against the heat conducting plate 512, the heat conducting plate 512 moves away from the shell. At this time, the elastic member 9 is compressed due to the movement of the heat conducting plate 512, and a rebound force is generated to make the heat conducting plate 512 react on the reaction tube 4, forming a downward pressing force on the reaction tube 4; and since the heating plate 511 and the fastening plate 52 move together with the heat conducting plate 512, the heat generated by the heating plate 511 is effectively transferred to the heat conducting plate 512, and then transferred to the reaction tube cover 41. In addition, due to the elastic member 9, the heat conducting plate 512 is movable. Therefore, for reaction tubes 4 of different heights, the top cover heating module 5 can be adaptively adjusted and can be used for reaction tubes 4 of different heights.

[0043] For example, in this embodiment, in order to facilitate the installation of the top cover heating module 5, a top plate 31 adapted thereto may be provided inside the top cover 3, and the top plate 31 is installed in the cavity of the top cover 3, so as to facilitate the fixing of the top cover heating module 5. Specifically, a avoidance opening 311 and a first installation opening 312 are formed on the top plate 31, and the shape of the avoidance opening 311 is adapted to the top cover heating module 5, and is used for the installation and movement of the top cover heating module 5, specifically, the heating plate 511 is fixed on the first side surface of the heat conducting plate 512, and the first side surface is away from the heating tube, the fastening plate 52 is arranged on the outside of the heating plate 511, and the fastening plate 52 is fixedly connected to the heat conducting plate 512, so that the heating plate 511 is clamped between the fastening plate and the heat conducting plate, thereby completing the assembly of the top cover heating module 5.

[0044] Among them, mounting holes 5121 are respectively opened at both ends of the heat conducting plate 512, and the assembled top cover heating module 5 is placed in the avoidance opening 311, and the mounting holes 5121 opened at both ends of the heat conducting plate 512 pass through the connecting column 32 and press against the elastic member 9 sleeved on the outside of the connecting column 32, and are threadedly connected to the end of the connecting column 32 by screws, so as to restrict the top cover heating module 5 on the connecting column 32 in the avoidance opening 311; wherein, the connecting column 32 is formed on the inner wall surface of the top cover 3 and extends toward the shell direction.

[0045] For example, in order to enable the heat conducting plate 512 to better conduct the heat of the heating plate 511 , a heat conducting glue may be provided between the heat conducting plate 512 and the heating plate 511 .

[0046] For example, the top cover may not be provided with the elastic member 9, and after the heating plate 511 and the fastening plate 52 are fixed on the heat conducting plate 512, the heat conducting plate 512 is fixed in the top cover through the connecting column 32. When the shell and the top cover are closed, the heat conducting plate 512 contacts the reaction tube cover 41 and exerts a slight downward pressing force on the reaction tube. This method can only be applied to reaction tubes of a given height, and cannot be applied to reaction tubes of different heights. However, for portable detection equipment, only one reaction tube of a given height can be applied, which can also meet the detection requirements.

[0047] More preferably, in order to enable the heat conducting plate 512 to better conduct the heat of the heating plate 511 , a heat conducting glue may be provided between the heat conducting plate 512 and the heating plate 511 .

[0048] For example, in this embodiment, when the heating plate 511 is heated, in order to prevent the fastening plate 52 from sharing part of the heat of the heating plate 511 and causing heat loss, the fastening plate 52 can be made of a high temperature resistant heat insulating material. Therefore, when the heating plate 511 is heated, the heat conducting plate 512 can conduct the heat generated by the heating plate 511 to the heating tube cover 41 as much as possible.

[0049] For example, Figure 6 As shown, the top pin connector is a spring pin connector 6, which includes a conductive connector male end 61 and a connector female end 62; one of the connector male end 61 and the connector female end 62 is arranged in the top cover 3 and connected to the heating plate 511 of the top cover heating module 5, and the other of the connector male end 61 and the connector female end 62 is arranged in the shell 2 and connected to the control module 1.

[0050] like Figure 6 As shown, the connector male end 61 adopts a spring needle commonly used in the market, and the connector male end 61 includes a needle tube 611, a welding terminal 612, a spring 613 and a needle shaft 614. The needle tube 611 is a cavity structure with a closed bottom and an open top. The spring 613 is installed in the needle tube 611 and one end is connected to the bottom of the needle tube 611. The other end of the spring 613 is connected to the needle shaft 614 that can be retracted back and forth in the needle tube 611. The bottom of the needle tube 611 is connected to the welding terminal 612. The connector female end 62 adopts a commonly used copper column. Of course, other types of connector male ends and connector female ends on the market can also be used, as long as the two can achieve signal conduction.

[0051] For example, Figure 5As shown, taking the connector male end 61 disposed in the top cover 3 as an example, the heating plate 511 is welded and connected to the welding terminal 612 of the connector male end 61 through a wire, thereby realizing the connection between the two. Then the corresponding connector female end 62 is disposed in the housing 2, so the control module 1 is also welded and connected to the welding terminal of the connector female end 62 through a wire, thereby realizing the connection between the two. The connector male end 61 is installed on the first installation port 312. Of course, the connector female end can also be disposed in the top cover and the connector male end can be disposed in the housing, and the conduction of the circuit can also be realized.

[0052] For example, in order not to change the general structure of the shell of the existing molecular detection equipment, corresponding improvements can be made on the original structure, such as the original mounting plate in the shell for mounting the carrying module, the carrying module is used to carry the reaction tube, so we can make slight improvements on the mounting plate to install the male end of the connector or the female end of the connector. For example, the female end of the connector 62 is installed in the shell 2, and a second mounting port 211 can be opened on the mounting plate 21 provided in the shell 2. The second mounting port 211 is used to install the female end of the connector 62. Then, correspondingly, the male end of the connector 61 is installed in the first mounting port 312 provided on the top plate. The positions where the first mounting port 312 and the second mounting port 211 are opened correspond to each other, so that the male end of the connector and the female end of the connector can be correspondingly connected.

[0053] The control module 1 can control whether the heating plate 511 is heated by connecting the male end of the connector and the female end of the connector. Therefore, the spring pin connector 6 is used in this application to replace the traditional wiring method to achieve the connection of the circuit. This is because the traditional wiring method, if the wiring is exposed, is not beautiful and causes a large loss to the wiring. Frequent opening of the cover will cause the loss of the wiring and damage the instrument. If the wiring is hidden, that is, the wiring is set in the shaft, this method is more complicated and requires a precise shaft design. At the same time, the complex structure will cause the instrument to expand in size and be inconvenient to carry.

[0054] In one embodiment, the micro POCT detection device of the present application further includes a temperature sensor, which can be installed in the top cover 3 or in the housing 2. The following is a detailed description:

[0055] First, when the temperature sensor is disposed in the top cover 3, the temperature sensor and the top cover heating module are disposed in the top cover 3 together, so the temperature sensor and the heating plate 511 of the top cover heating module 5 can be directly connected by wires to collect temperature information of the top cover heating module 5. Since the installation position of the control module 1 is not improved, that is, the control module 1 is still disposed in the housing 2, in order to realize the connection between the temperature sensor and the control module 1, the temperature sensor is connected to the control module through a spring pin connector, so that the temperature sensor transmits the collected temperature information to the control module 1, and the control module 1 controls the opening or closing of the top cover heating module 5 and the heating power of the top cover heating module 5 after processing the received temperature information.

[0056] Among them, since the spring pin connector not only needs to connect the control module 1 and the heating plate of the top cover heating module, but also needs to connect the control module 1 and the temperature sensor, there are at least 4 spring pin connectors, such as Figure 4 As shown, the present application has four spring pin connectors, two of which are used to connect the control module and the heating plate of the top cover heating module, and the other two spring pin connectors are used to connect the control module 1 and the temperature sensor.

[0057] In which, taking the connector male end 61 of the spring pin connector 6 disposed in the top cover 3 as an example, the temperature sensor is connected to the welding terminal 612 of the connector male end 61 by welding through a wire. The welding terminal of the connector female end 62 is connected to the control module 1, so the electrical connection between the temperature sensor and the control module 1 can be achieved through the conduction between the connector female end 62 and the connector male end 61.

[0058] The second type is that when the temperature sensor is arranged in the housing 2, the temperature sensor and the control module 1 are both located in the housing 2, so the temperature sensor and the control module 1 can be directly connected by wires, and the collected temperature information can be transmitted to the control module. At this time, the temperature sensor is far away from the top cover heating module 5, so in order to smoothly collect the temperature information of the top cover heating module 5, the temperature sensor is connected to the top cover heating module 5 through a spring pin connector, and the temperature information of the top cover heating module 5 is collected through the spring pin connector 6 and transmitted to the control module. After the control module processes the received temperature information, it controls the opening or closing of the top cover heating module 5 and controls the heating power of the top cover heating module 5.

[0059] Similarly, the spring pin connector 6 not only needs to connect the control module 1 and the heating plate of the top cover heating module 5, but also needs to connect the temperature sensor and the heating plate of the top cover heating module, so at least 4 spring pin connectors are provided. Figure 1-5As shown, the present application has four spring pin connectors, two of which are used to connect the control module and the heating plate of the top cover heating module, and the other two spring pin connectors are used to connect the temperature sensor and the heating plate of the top cover heating module.

[0060] In which, taking the connector female end 62 of the spring pin connector 6 disposed in the housing 2 as an example, the temperature sensor is connected to the welding terminal of the connector female end by welding through a wire. The welding terminal 612 of the connector male end is connected to the heating plate, and the temperature sensor can collect the temperature information of the heating plate of the top cover heating module 5 through the conduction between the connector male end and the connector female end.

[0061] When there are four spring pin connectors, two of them are used for heating power and the other two are used for data acquisition. Therefore, the number of spring pin connectors can be greater than four, and all of them can be used as power lines, control lines, and data lines.

[0062] In one embodiment, Figure 1-5 As shown, a micro POCT detection device of the present application also includes a first magnetic member 71 and a second magnetic member 72 that can attract each other. The first magnetic member 71 and the second magnetic member 72 are respectively and correspondingly arranged on the end surfaces where the top cover and the shell are in contact, and are used to cover the top cover and the shell.

[0063] Furthermore, the present application discloses a micro POCT detection device further including a plastic part 8, wherein two plastic parts 8 are provided, and the two plastic parts 8 are respectively provided in the top cover and the shell, and the magnetic part is fixed in the plastic part. Specifically, the two plastic parts 8 are respectively named as the first plastic part 81 and the second plastic part 82. Since the spring pin connector 6 is composed of a split connector male end 61 and a connector female end 62, taking the connector female end 62 provided in the shell 2 as an example, in order to further fix the connector female end 62, the connector female end 62 can be embedded in the second plastic part 82, and the second magnetic part 72 is also embedded in the second plastic part 82, and the second plastic part 82 is fixed on the second mounting port 211 of the mounting plate 21 in the shell 2.

[0064] Similarly, the connector male end 61 and the first magnetic attraction member 71 are embedded in the first plastic member 81, and the first plastic member 81 is fixed to the first mounting opening 312 of the top plate 31 in the top cover 3. Therefore, when the housing 2 and the top cover 3 are closed, the needle shaft 614 of the connector male end 61 can contact with the connector female end 62 to achieve conduction.

[0065] For example, the connector male end 61, the first magnetic member 71 and the first plastic member 81 can be integrally formed by a bonding process; the connector female end 62, the second magnetic member 72 and the second plastic member 82 can be integrally formed by a bonding process. For example, since the connector male end / connector female end, the magnetic member and the plastic member are integrally formed, a magnetic connector having all three parts can also be purchased directly from the market.

[0066] Taking the example that the temperature sensor is arranged in the top cover 3, the connector male end 61 is arranged in the top cover 3, and the connector female end 62 is arranged in the shell 2, the working process of the device of the present application is described in detail: when the top cover 3 and the shell 2 are closed, the control module 1 is connected to the heating plate of the top cover heating module 5 through the connector female end 62 and the connector male end 61, and the control module 1 is connected to the temperature sensor through the connector female end 62 and the connector male end 61. After receiving the temperature information collected by the temperature sensor and processing it, it is compared with the set value to determine whether the heating plate needs to be heated. If heating is required, the power of the heating plate is adjusted by conducting the connector female end 62 and the connector male end 61, so as to control the heating temperature of the heating plate and achieve temperature control.

[0067] In one embodiment, the micro POCT detection device of the present application can also be a portable nucleic acid detector, such as Figure 7 The nucleic acid detector can also heat and control the reaction tube cover by setting a magnetic connector, a top cover heating module, and combining a control module and a temperature sensor.
