Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a test tube shaker for medical testing. Background Technology

[0002] Current mainstream test tube shakers have achieved significant breakthroughs in core functionality and compatibility. Their multi-level oscillation frequency adjustment system and freely adaptable clamp components not only accurately output uniform oscillation force to ensure thorough mixing of reagents in test tubes, meeting the needs of molecular experiments, sample pretreatment, and other scenarios, but also flexibly accommodate various test tube types, from 1.5mL centrifuge tubes to 50mL centrifuge tubes and ELISA plates, eliminating the need for frequent replacement of parts and greatly improving experimental efficiency.

[0003] However, existing equipment still has significant shortcomings: on the one hand, the open motor drive structure used in most models lacks effective noise reduction design. During high-speed oscillation, the noise generated by mechanical friction and airflow disturbance often exceeds 65 decibels, which can easily interfere with the laboratory environment and may also affect the operator's concentration in the long run. On the other hand, the equipment itself does not integrate a temperature control module. When processing temperature-sensitive biological samples, it is necessary to use additional temperature control devices such as water baths and incubators, which not only increases the purchase cost of experimental equipment, but also requires manual transfer of test tubes, which prolongs the operation process and may also affect the sample activity and the accuracy of experimental results due to temperature fluctuations.

Detailed Implementation

[0019] 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.

[0020] As attached Figure 1 With appendix Figure 5 The medical testing tube shaker shown includes a housing 1, which is cylindrical and has an internal space. A bearing 16 is installed in the internal space of the housing 1, located at the bottom center of the internal space of the housing 1. A buffer shaft 8 is rotatably mounted on the bearing 16, and an auger blade is wrapped around the buffer shaft 8. A support rod 14 is movably mounted on the buffer shaft 8. The support rod 14 is a hollow cylinder with internal threads that mesh with the auger blade of the buffer shaft 8. Rotating the support rod 14 allows for up-and-down movement.

[0021] The space between the interior of the housing 1 and the outer wall is a hollow area 17. Multiple partitions 13 are set on the support rod 14 to divide the support rod 14 into multiple parts. In order to facilitate the rotation of the support rod 14, multiple rotating blocks 9 are set at the uppermost end of the support rod 14. The rotating blocks 9 and the support rod 14 are a whole. When the rotating blocks 9 are rotated, the support rod 14 also rotates and moves vertically up and down along the buffer shaft 8.

[0022] Multiple test tube racks 11 are installed on the support rods 14 between the partitions 13 to fix the test tubes. To make the test tubes more stable, multiple placement grooves 12 are set on the partitions 13. The number of placement grooves 12 and test tube racks 11 are the same and correspond one-to-one, which makes the test tubes more stable. A resonant plate 15 is also set on each partition 13. A piezoelectric ceramic 10 is set on the resonant plate 15. A power supply is set on the bottom partition 13 to supply power to the piezoelectric ceramic 10. The piezoelectric ceramic 10 vibrates as a vibration source, and the vibration is amplified by the resonant plate 15 and transmitted to the partition 13, so that the entire vibration device produces the required intensity of oscillation. In order to make the vibration more uniform, the piezoelectric ceramics 10 are staggered.

[0023] A liquid injection port 6 is provided at the bottom of the chamber 1 for injecting liquid into the hollow area 17 of the chamber 1. The injected liquid is glycerin. After the liquid injection is completed, the injection port 6 is blocked by a piston 7 to ensure that the added liquid does not leak out and to play a role in sound insulation. A heater 2 is provided at the lower end of the chamber 1. The heater 2 includes a copper tube 201 and a controller 202. The copper tube 201 is located in the hollow area 17 of the chamber 1 and is in direct contact with the added liquid. The controller 202 is located on the outside of the chamber 1 and is used to control the copper tube 201 to heat the added liquid to the ideal temperature to achieve a constant temperature effect. An observation window 3 is also provided on the side of the chamber 1. The observation window 3 is composed of glass blocks, and the middle of the glass blocks is a vacuum part, which plays a role in sound insulation.

[0024] To ensure the sound insulation effect of the enclosure 1, the enclosure 1 is equipped with a sound insulation cover 4. The inside of the sound insulation cover 4 is filled with a large amount of sponge to reduce noise. A handle 5 is provided on the sound insulation cover 4 to facilitate the opening and closing of the sound insulation cover 4.

[0025] First, rotate the chamber 1 180 degrees and inject the required liquid through the injection port 6. After filling, cover the piston 7 and rotate the chamber 1 back to its original state. Then, start the heater 2 to raise the added liquid to the required temperature. Next, fix the test tube to be vibrated on the test tube rack 11 and rotate the rotating block 9 to make the entire vibration device rotate along the buffer shaft 8 into the chamber 1, while making the test tube vibrate initially. Then, start the piezoelectric ceramic 10 to make the entire vibration device vibrate. Finally, hold the handle 5 and put the soundproof cover 4 on the chamber 1, and observe the state of the liquid in the test tube through the observation window 3. When the required state is reached, hold the handle 5 to open the soundproof cover 4, then rotate the rotating block 9 to move the vibration device out of the chamber 1. Then, turn off the vibration device and take out the test tube.
