Problems solved by technology

Because it is difficult to stir evenly with a glass rod, and it is easy to cause the sample liquid to splash during the stirring process, which not only affects the accuracy of the detection, but also has biochemical safety problems.
[0003] So we thought of magnetic stirring. Through experiments, we found that the existing magnetic stirring devices have the problems of unconcentrated magnetic field design, inconvenient installation of magnets, low efficiency, unreasonable design of magnetic particles, and low stirring performance.

Embodiment Construction

[0014] Such as figure 1 Shown, a kind of magnetic stirring device and manufacture method thereof, comprise stirring motor 1, mounting base 2, permanent magnet 3, magnetic particle 5, sample box 4, described mounting base 2 is provided with a central hole, and described stirring motor 1 is fixed on the installation base 2, and the output shaft of the stirring motor 1 is connected with the permanent magnet 3 through the central hole. The permanent magnet 3 is arc-shaped with a sleeve 7. The arc-shaped design is ingenious, which makes the magnetic field focus more concentrated, and has a stronger force on the magnetic particles 5 in the sample box 4. It also improves equipment efficiency and reduces energy consumption. . The sleeve pipe 7 of the permanent magnet 3 is fixed on the output shaft of the stirring motor 1 with screws.

[0015] The sample box is placed in front of the permanent magnet, and the magnetic particles 5 for stirring are placed in the sample box. The magneti...

Abstract

The invention relates to a magnetic stirring device and a manufacturing method thereof. The magnetic stirring device comprises a stirring motor, a mounting base, a permanent magnet, a magnetic particle and a sample box, wherein the stirring motor is fixedly installed on the mounting base, the permanent magnet is installed on an output shaft of the stirring motor, the sample box is arranged in front of the permanent magnet, and a magnetic particle used for stirring is arranged in the sample box. The magnetic stirring device has the advantages of sanitation in operation, high stirring speed and good stirring uniformity.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a magnetic stirring device for experiment or inspection. Background technique [0002] In the inspection process of human or animal secretions, hospitals now use small plastic cups and cotton swabs, or use small bamboo boards and small spoons for sampling. Then the inspectors take some of these collected samples based on experience, add an appropriate amount of diluent and stir with a glass rod to make a suspension, smear it on a glass slide and observe it under a microscope, then record the observation results, and issue a test report. Report. Because it is difficult to stir evenly with a glass rod, and it is easy to cause the sample liquid to splash during the stirring process, which not only affects the accuracy of the detection, but also has biochemical safety problems. [0003] So we thought of magnetic stirring. Through experiments, we found that the existing magnetic s...
