Description

Technical Field

[0001] This utility model relates to the field of nucleic acid detection technology, specifically a nucleic acid concentration multi-sample detection device. Background Technology

[0002] Nucleic acids are one of the most basic biological macromolecules that make up living organisms. They can store and transmit genetic information. Nucleic acids need to be detected in many fields such as life sciences, public health and social management. Nucleic acid concentration detection is a technical method for quantitative analysis of the nucleic acid content in a nucleic acid sample. It can accurately determine the concentration of nucleic acids and provide accurate data support for subsequent experiments.

[0003] An investigation revealed a Chinese utility model patent (Publication No.: CN222099976U) disclosing a nucleic acid concentration detection and homogenization device, comprising a body and a sample rack. Multiple sample racks are arranged in a linear matrix on the upper surface of the body. Each sample rack includes a shell and an overlapping assembly. The shell includes a placement cavity extending through both vertical ends of the shell. The overlapping assembly includes a slider and an overlapping plate, with the overlapping plate slidably connected to the slider in a horizontal direction. The shell has through slots on its opposite side walls for the slider to slide vertically. One end of the overlapping plate is movable into the placement cavity. Using this device, it is more convenient for staff to place experimental sample plates into the sample rack.

[0004] Although the aforementioned patent improves the portability of the test tubes by using the overlapping components and the cooperation between the slider and the overlapping plate, the sliding overlapping plate makes it easier for operators to place the test tubes into the box for testing. However, since there are many samples to be tested, the component still requires operators to place the test tubes separately into the placement chamber and then slide them into the box for testing. This operation is cumbersome and inefficient, which is not conducive to improving the testing efficiency.

[0005] Therefore, this invention provides a nucleic acid concentration multi-sample detection device to solve the above problems. Utility Model Content

[0007] This invention provides a nucleic acid concentration multi-sample detection device, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A nucleic acid concentration multi-sample detection device includes a housing, a support pad is fixedly connected to the bottom end of the housing, and a detection component is arranged inside the housing;

[0011] The detection assembly includes a fixed frame fixedly connected to the inner wall of the chamber. A limiting slide is fixedly connected to the outer wall of the fixed frame. A slide rod is slidably connected to the inner wall of the limiting slide. A test tube holder is fixedly connected to the outer wall of the slide rod.

[0017] (III) Beneficial Effects

[0018] By setting up a detection component, detection efficiency can be improved. The uniformly spaced test tube holders allow operators to easily place multiple test tubes into the holders simultaneously. Utilizing the coordinated movement of a limiting slide, sliding rod, telescopic spring, sliding block, and abutment rod, the operator closes the lid and presses down the abutment rod, causing the test tube holders to move downwards. The limiting slide further restricts the movement of multiple test tube holders, increasing the distance between the test tubes and facilitating detection by the instrument, thus improving efficiency. This component has a simple structure and high practicality. The automatically resetting and uniformly spaced test tube holders allow operators to place test tubes into the holders in batches for testing at once, reducing operator workload and increasing efficiency.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This invention provides a multi-sample nucleic acid concentration detection device, such as... Figures 1-5As shown, the nucleic acid concentration multi-sample detection device includes a box 1, a support pad is fixedly connected to the bottom of the box 1, and a detection component is installed inside the box 1.

[0028] The testing assembly includes a fixed frame 2 fixedly connected to the inner wall of the housing 1, a limiting slide 3 fixedly connected to the outer wall of the fixed frame 2, a slide rod 4 slidably connected to the inner wall of the limiting slide 3, a test tube holder 5 fixedly connected to the outer wall of the slide rod 4, the side walls of multiple test tube holders 5 being fixedly connected by a telescopic spring 6, a slide seat 7 fixedly connected to the inner bottom of the housing 1, an abutment rod 8 slidably connected to the inner wall of the slide seat 7, a telescopic locking ball 9 fixedly connected to the side wall of the abutment rod 8, a locking groove opened on the inner wall of the slide seat 7, and an adjustment component provided on the side wall of the test tube holder 5.

[0029] A pressing rod 14 is fixedly connected to the upper top of the abutment rod 8, and a return spring 15 is fixedly connected to the lower bottom of the slide block 7.

[0030] The top of the box body 1 is connected to the box cover 16 by a hinge. The top of the box body 1 is provided with a snap-fit ​​groove 17. The bottom of the box cover 16 is connected to the snap-fit ​​groove 17 by a snap-fit ​​rod 18.

[0031] Specifically, the support pad at the bottom of the box 1 provides sufficient support to ensure its stability during the testing process. The testing components allow operators to test multiple nucleic acid tubes at once. Multiple tubes are clamped together using a uniform clamp. Because the spacing of the tube holders 5 is uniform, operators can quickly place the tubes into the tube holders 5 and then close the lid 16. The closing of the lid 16 causes the downward-pressing rod 14 to move. When the downward-pressing rod 14 slides longitudinally, it causes the abutment rod 8 to move downwards, thus abutting against the tube holders 5. The sliding rods 4 on the side walls of the multiple tube holders 5 are limited by the sliding frame 3. Because of the limited position, the tubes will scrape along the groove inside the limiting slide 3, thus achieving rapid separation and increasing the distance between the test tubes for easier testing. Since the side wall of the abutment rod 8 is equipped with a telescopic locking ball 9, it will be locked by the locking groove inside the slide 7 when it slides down. When the test is completed, the operator opens the box cover 16 and pulls the downward pressing round rod 14 to separate the telescopic locking ball 9 from the locking groove. Since the side walls of multiple test tube seats 5 are connected by telescopic springs 6, they will return to their original position as the springs contract when they move upward, making it easy for the operator to remove the test tubes. This component has a simple structure, is highly practical, and can improve the testing efficiency by facilitating nucleic acid testing for operators.

[0032] The adjustment assembly includes an adjustment rod 10 threaded to the side wall of the test tube holder 5, a friction plate 11 fixedly connected to the end of the adjustment rod 10, and a knob fixedly sleeved at the end of the adjustment rod 10 away from the friction plate 11.

[0033] The adjustment assembly also includes a compression spring 12 fixedly connected to the inner wall of the test tube holder 5, with an annular washer 13 fixedly connected to the end of the compression spring 12, and a digital rotary wheel rotatably connected to the top of the test tube holder 5.

[0034] A detector 19 is fixedly connected to the inner wall of the enclosure 1, a reflector 20 is fixedly connected to the bottom inner end of the enclosure 1, and a display is fixedly connected to the top of the enclosure cover 16.

[0035] Specifically, when the test tube is slightly smaller than the test tube holder 5, the adjusting rod 10 on the side wall of the test tube holder 5 is adjusted. By rotating the knob on the outer wall of the adjusting rod 10, the friction plate 11 at the end of the adjusting rod 10 continuously contracts inward, thus squeezing the test tube. Through friction, the test tube is stably pressed against the inside of the test tube holder 5. At the same time, when the test tube is placed, the compression spring 12 on the side wall of the test tube holder 5 will also cause the annular gasket 13 to contract. When the test tube is placed, the squeezing force of the spring can further improve the stability of the test tube and prevent the test tube from slipping during the test. The digital wheel rotating at the top of the test tube holder 5 makes it easier for the operator to distinguish the nucleic acid samples inside the test tube, improving the accuracy of the test data. The detector 19 inside the box 1 can quickly test multiple samples, saving test time and improving test efficiency.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
