Description

Technical Field

[0001] This utility model relates to the field of fluorescence quantitative detection technology, and in particular to a portable fluorescence quantitative PCR instrument with a PCR module. Background Technology

[0002] Quantitative fluorescence detection technology refers to a method that adds fluorescent probe groups to the PCR reaction system and uses the accumulation of fluorescence signals to quantitatively analyze the target analyte.

[0003] In existing quantitative PCR instruments, most require pulling and retrieving the test items, which is inconvenient for personnel and makes it difficult for them to position the instrument during use. This can cause the instrument to shake and affect the accuracy of the test data. Therefore, those skilled in the art provide a movable quantitative PCR instrument with a PCR module to solve the problems mentioned in the background. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0023] Reference Figures 1-4 A portable real-time PCR instrument with a PCR module includes a real-time PCR instrument body 1. A square groove is provided on one side of the front of the real-time PCR instrument body 1. An ejection component 2 is provided inside the square groove. A detection stage 3 is provided on the top of the ejection component 2. The ejection component 2 includes an ejection spring 21 fixedly connected to both sides of the inner wall of the square groove. A placement plate 22 is fixedly connected to one end of the ejection spring 21. A sealing plate 23 for fixing is fixedly connected to one side of the placement plate 22.

[0024] With the ejector component 2 and the main body 1 of the real-time PCR instrument, when personnel need to test an item, the item to be tested can be placed on top of the testing platform 3. Then, the personnel can push the placement plate 22 to make the rolling ball 9 fit against the two side walls inside the square groove, causing the ejector spring 21 to retract. Then, the locking block 8 can be locked onto the inner wall of the square groove, allowing the testing platform 3 to quickly test the item. Afterwards, when personnel need to remove the item, they can press the locking block 8 to retract the locking spring 7, causing the ejector spring 21 to be released from its constraint. Then, the ejector spring 21 drives the placement plate 22 to pop out automatically, making it convenient for personnel to remove the item to be tested.

[0025] In this utility model, both sides of the outer surface of the main body 1 of the fluorescence quantitative PCR instrument are fixedly connected to the connecting pieces 4. The middle of the top surface of the connecting piece 4 is threaded through a positioning component 5 for improving stability. The positioning component 5 includes a threaded rod 51 threadedly connected to the inside of the connecting piece 4. The bottom of the threaded rod 51 is rotatably connected to a suction cup 52.

[0026] With the positioning component 5 and the main body 1 of the real-time PCR instrument, when personnel need to position the main body 1 of the real-time PCR instrument, they can place the main body 1 of the real-time PCR instrument in the designated working position, and then the personnel can turn the threaded rod 51 to move the suction cup 52 downward, so that the suction cup 52 is attached to the designated table, thereby facilitating the personnel to quickly fix the main body 1 of the real-time PCR instrument.

[0027] In this utility model, square pieces 6 are fixedly connected to both sides of the placement plate 22, a snap-fit ​​spring 7 is fixedly connected to one side of the square piece 6, a snap-fit ​​block 8 is fixedly connected to one end of the snap-fit ​​spring 7, and a rolling ball 9 is rotatably connected inside the snap-fit ​​block 8.

[0028] With the setting of snap-fit ​​spring 7 and rolling ball 9, when personnel need to fix and constrain the placement plate 22, snap-fit ​​block 8 moves along the square groove to the snap-fit ​​position, and then snap-fit ​​spring 7 drives snap-fit ​​block 8 to pop out to both sides of the fluorescent quantitative PCR instrument body 1, thereby facilitating the personnel to fix the placement plate 22.

[0029] In this utility model, a screw is threadedly connected to one side of the main body 1 of the fluorescence quantitative PCR instrument, and a maintenance plate 10 for maintenance is threadedly connected to the surface of the screw. A card plate 11 is provided at the adjacent position of the square piece 6, and heat dissipation grooves are equidistantly opened on the surface of the card plate 11.

[0030] With the installation of the inspection plate 10 and screws, when personnel need to maintain the main body 1 of the real-time PCR instrument, they can unscrew the screws to disassemble the inspection plate 10, thereby disassembling the main body 1 of the real-time PCR instrument and facilitating the maintenance of the main body 1 of the real-time PCR instrument.

[0031] In this utility model, a display screen 12 for displaying data is embedded on one side of the top surface of the real-time PCR instrument body 1, and a control panel 13 is provided on the adjacent side of the front of the real-time PCR instrument body 1.

[0032] With the settings of the display screen 12 and control panel 13, when personnel are observing the test data, they can use the control panel 13 to start the power of the real-time PCR instrument 1, so that the display screen 12 will start displaying the data, thus facilitating the use of the real-time PCR instrument 1.

[0033] Working principle: When the real-time PCR instrument 1 is needed, the personnel can place the item to be tested on the top of the testing platform 3. Then, the personnel can push the placement plate 22 to make the rolling ball 9 fit against the two side walls inside the square groove, causing the spring 21 to retract. Then, the locking block 8 can be locked onto the inner wall of the square groove, allowing the testing platform 3 to quickly test the item. Afterwards, when the personnel need to remove the item, they can press the locking block 8 to retract the locking spring 7, causing the spring 21 to be released from its constraint. Then, the spring 21 drives the placement plate 22 to pop out automatically. Next, when the personnel need to position the real-time PCR instrument 1, they can place the real-time PCR instrument 1 in the designated working position. Then, the personnel can turn the threaded rod 51 to move the suction cup 52 downwards, causing the suction cup 52 to adhere to the designated table surface. Afterwards, when the personnel need to observe the test data, they can use the control panel 13 to turn on the power of the real-time PCR instrument 1, so that the display screen 12 starts to display the data.
