Description

Technical Field

[0001] This utility model relates to the field of biological sampling technology, specifically a biological sampling preservation device. Background Technology

[0002] Biological sampling is the process of obtaining samples from organisms and analyzing, testing, or studying them. It can involve different types of organisms. During biological sampling, in order to ensure the accuracy and integrity of the samples, it is necessary to use suitable preservation devices to store them for subsequent research.

[0003] A microbial sampling preservation device, with announcement number CN222512455U, comprises a storage tank as the main body. A sealing cover is installed on the top side of the storage tank, and the connection between the sealing cover and the storage tank is sealed by a sealing strip. A storage component is provided inside the storage tank. A temperature monitor is installed at the center of the top side of the sealing cover. Connecting blocks are symmetrically fixed on the circumferential surface of the top side of the storage tank. A sleeve plate is installed inside the connecting block, and an L-shaped telescopic pressure plate is installed inside the sleeve plate. The L-shaped telescopic pressure plate is fastened to the top side of the sealing cover. The sealing cover can effectively prevent air and external pollutants from entering the storage tank, thereby preventing the microbial samples inside the storage tank from being affected by external factors, so as to facilitate subsequent research on the microbial samples.

[0004] The above-described microbial sampling preservation device still has a problem. During the use of this device, when storing and retrieving microbial samples, the sealed lid needs to be opened. At this time, the inside of the storage tank is exposed to the external environment, which makes its internal temperature or other factors easily affected by the external environment, resulting in inaccurate research results of microbial samples. Therefore, a biological sampling preservation device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, commercially available preservation devices require opening the sealed lid when storing or retrieving microbial samples. This exposes the inside of the storage container to the external environment, making its internal temperature or other factors susceptible to external influences, resulting in inaccurate research results for microbial samples. This invention proposes a preservation device for biological sampling.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The biological sampling preservation device of this utility model includes a tank; an access mechanism is provided on the inner side of the tank, a positioning mechanism is provided at the top of the inner side of the tank, a detection mechanism is provided on the circumferential surface of the tank, and a mounting base is fixed at the bottom of the inner side of the tank.

[0007] Preferably, the storage and retrieval mechanism includes a mounting base, a shaft rotatably mounted inside the mounting base, brackets evenly fixed on the bottom circumferential surface of the shaft, a limit frame evenly fixed on the circumferential surface of the shaft, a storage tank fastened to the inner side of the limit frame by a limit block, a discharge port opened on the top side of the tank, a rubber stopper fastened to the inner side of the discharge port, a lead screw rotatably mounted inside the tank, a drive motor fixed at the top edge of the tank, a push plate slidably mounted inside the tank, a servo motor fixed at the center of the top side of the tank, the output end of the servo motor passing through the tank and fixedly connected to the shaft, the push plate rotatably connected to the lead screw, and the output end of the drive motor passing through the tank and rotatably connected to the lead screw. Through the cooperation of the lead screw and the push plate, the storage tank can be pushed out from the discharge port or loaded into the storage tank from the discharge port, thereby reducing the impact of the external environment on the inner side of the tank.

[0008] Preferably, the positioning mechanism includes a disc with positioning holes evenly distributed on its surface. A limiting plate is fixed to the top of the inner side of the tank, and a rod is slidably inserted through the bottom side of the limiting plate. A limiting cap is fixed to the bottom of the rod, and a spring is fixedly connected between the limiting cap and the limiting plate. The spring is fitted onto the rod, and the disc is fixed to the top of the shaft. By cooperating with the positioning holes, the biological sample can be accurately moved to the discharge port, thus facilitating the storage and retrieval of the biological sample.

[0009] Preferably, the detection mechanism includes a glass tube with graduated grooves on its circumference. Both ends of the glass tube are connected to the inside of the tank through through holes. The glass tube is fixed to the circumference of the tank. An input valve is installed on the top circumference of the tank, and an output valve is installed on the bottom circumference of the tank. Through the structure of the glass tube, the input valve, and the output valve, the liquid level inside the tank can be adjusted as needed, and the biological sample will not be affected by external factors.

[0010] The advantages of this utility model are:

[0011] 1. This utility model, through the structural design of a biological sampling preservation device, sets up a storage and retrieval mechanism, controls a servo motor to move the storage tank to the bottom of the discharge port, at which point the drive motor drives the push plate to slide upward, the push plate contacts the limit block, and drives the storage tank to rise, so that it extends out from the discharge port, thereby removing the storage tank. This solves the problem that existing preservation devices are easily affected by the external environment when storing and retrieving samples.

[0012] 2. This utility model, through the structural design of a biological sampling preservation device, sets up a positioning mechanism. When the shaft rotates, it drives the disc to rotate. At this time, the disc pushes the insertion rod to slide downward, thereby stretching the spring. When the biological sample is moved to the required position, the positioning hole moves to the top side of the insertion rod. The spring pushes the insertion rod to extend through its elastic force, causing the insertion rod to be fastened inside the positioning hole, thereby positioning the biological sample inside the container and facilitating the storage container.

[0020] 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 scope of protection of the present utility model.

[0021] Please see Figure 1-4As shown, a biological sampling preservation device includes a container 1; an access mechanism is provided on the inner side of the container 1, a positioning mechanism is provided at the top of the inner side of the container 1, a detection mechanism is provided on the circumferential surface of the container 1, and a mounting base 4 is fixed at the bottom of the inner side of the container 1.

[0022] Please see Figure 2 As shown, the storage and retrieval mechanism includes a mounting base 4, a shaft 3 rotatably mounted inside the mounting base 4, brackets 5 evenly fixed on the bottom circumferential surface of the shaft 3, and limit frames 6 evenly fixed on the circumferential surface of the shaft 3. A storage tank 8 is fastened to the inside of the limit frame 6 through a limit block 7. A discharge port 9 is opened on the top side of the tank 1, and a rubber stopper 10 is fastened to the inside of the discharge port 9. A lead screw 11 is rotatably mounted inside the tank 1. A drive motor 13 is fixed at the top edge of the tank 1. A push plate 12 is slidably mounted inside the tank 1. A servo motor 2 is fixed at the center of the top side of the tank 1. The output end of the servo motor 2 passes through the tank 1 and is fixedly connected to the shaft 3. The push plate 12 is rotatably connected to the lead screw 11. The drive motor 13 outputs... The outlet end passes through the tank body 1 and is rotatably connected to the lead screw 11. During operation, when encountering the problem that the internal environment of existing storage devices is easily affected when storing and retrieving biological samples, the structure of the storage mechanism controls the servo motor 2 to drive the output end shaft 3 to rotate, thereby moving the storage tank 8 inside the bracket 5 and the limiting frame 6 to the bottom side of the discharge port 9. At this time, the rubber stopper 10 is opened, and the drive motor 13 is controlled to drive the output end lead screw 11 to rotate, thereby driving the push plate 12 to slide upward inside the tank body 1. At this time, the push plate 12 contacts the limiting block 7, and through the limiting block 7, the storage tank 8 is raised, so that it extends out from the discharge port 9, thereby taking out the storage tank 8 so that the biological samples inside can be studied. This structure can reduce the impact of external factors on the sample storage environment.

[0023] Please see Figure 3 As shown, the positioning mechanism includes a disc 14 with positioning holes 15 evenly distributed on its surface. A limiting plate 16 is fixed to the top of the inner side of the tank 1, and a rod 17 is slidably inserted through the bottom of the limiting plate 16. A limiting cap 18 is fixed to the bottom of the rod 17, and a spring 19 is fixedly connected between the limiting cap 18 and the limiting plate 16. The spring 19 is fitted onto the rod 17, and the disc 14 is fixed to the top of the shaft 3. During operation, when a sample cannot be retrieved because it has not been moved to the correct position, the positioning mechanism works by rotating the shaft 3, which in turn rotates the disc 14. The disc 14 pushes the rod 17 downward, stretching the spring 19. When the biological sample is moved to the desired position, the positioning hole 15 moves to the top of the rod 17, and the spring 19 pushes the rod 17 to extend through its elastic force, causing the rod 17 to be fastened inside the positioning hole 15. This positions the biological sample inside the tank 1, facilitating the storage of the tank 8.

[0024] Please see Figure 4 As shown, the detection mechanism includes a glass tube 20 with a graduated groove 21 on its circumferential surface. Both ends of the glass tube 20 are connected to the inside of the tank body 1 via through holes 22. The glass tube 20 is fixed to the circumferential surface of the tank body 1. An input valve 24 is installed on the top circumferential surface of the tank body 1, and an output valve 23 is installed on the bottom circumferential surface of the tank body 1. During operation, when existing storage devices cannot adjust the liquid level in a timely manner, affecting the biological sample storage environment, the detection mechanism allows direct observation of the liquid level inside the tank body 1 via the graduated groove 21 on the circumferential surface of the glass tube 20. When adjustment of the liquid level inside the tank body 1 is required, the output valve 23 or the input valve 24 can be opened to discharge or inject liquid into the tank body 1, thereby promptly changing the liquid level inside the tank body 1 and making it easier for operators to use.

[0025] Please see Figure 5 As shown, a heat insulation pad 25 is fixedly mounted on the circumferential surface of the glass tube 20. During operation, when the external environment can easily affect the temperature change inside the storage device, the structure of the heat insulation pad 25 can separate the glass tube 20 from the external environment while making it convenient for operators to observe the liquid level, thus preventing the temperature change inside the glass tube 20 from affecting the storage environment of the storage device.

[0026] Working Principle: Biological sampling is the process of obtaining samples from organisms and analyzing, detecting, or researching them. It can involve different types of organisms. During biological sampling, to ensure the accuracy and integrity of the samples, suitable preservation devices are needed for storage so that they can be studied later. In existing preservation devices, the sealed lid needs to be opened when storing or retrieving microbial samples. This exposes the inside of the storage container to the external environment, making it susceptible to external influences on internal temperature and other factors, leading to inaccurate research results. To solve this problem, a storage and retrieval mechanism and a positioning mechanism are incorporated. Opening the rubber stopper 10 allows the stored sample to be retrieved through the outlet 9. The biological sample storage container 8 is placed inside the container 1, so that it is inserted between the support 5 and the limiting frame 6. At this time, the limiting block 7 on the circumferential surface of the storage container 8 is fastened to the top side of the limiting frame 6. Then, the rubber stopper 10 is fastened to the outlet 9 to prevent the inside of the container 1 from being affected by the external environment. During storage, the liquid level inside the container 1 can be directly observed through the graduated groove 21 on the circumferential surface of the glass tube 20. When it is necessary to adjust the liquid level inside the container 1, the output valve 23 or the input valve 24 can be opened to discharge the liquid inside the container 1 or inject liquid into the container 1, thereby changing the liquid level inside the container 1 in a timely manner and keeping the storage container 8 within a suitable environmental and temperature range.

[0027] When a biological sample needs to be retrieved, the servo motor 2 is controlled to rotate the output shaft 3. The shaft 3 rotates the disc 14, which pushes the insertion rod 17 downward, thus stretching the spring 19. When the biological sample is moved to the desired position, the positioning hole 15 moves to the top of the insertion rod 17. The spring 19 pushes the insertion rod 17 to extend through its elastic force, causing the insertion rod 17 to be fastened inside the positioning hole 15, thereby positioning the biological sample inside the tank 1. At this time, the shaft 3 drives the storage tank 8 inside the bracket 5 and the limiting frame 6 to move to the bottom of the discharge port 9. Open the rubber stopper 10 and control the drive motor 13 to drive the output screw 11 to rotate, thereby driving the push plate 12 to slide upward inside the tank 1. At this time, the push plate 12 contacts the limiting block 7 and drives the storage tank 8 to rise through the limiting block 7, so that it extends out from the discharge port 9, thereby taking out the storage tank 8. Then, the rubber stopper 10 is reattached to the discharge port 9, and the extracted biological sample is studied. This structure can reduce the impact of external factors on the sample storage environment and solve the problem that the existing preservation device is easily affected by the external environment when storing and retrieving samples.
