Description

Technical Field

[0001] This application relates to the field of medical storage device technology, and more specifically, to a magnetically driven oscillating thermostat for transporter storage. Background Technology

[0002] In fields such as biomedical testing and drug development, many liquid or suspension samples (such as whole blood, cell suspensions, and PCR reaction systems) are prone to sedimentation or stratification during static storage and transportation due to the uneven density of their internal components and the influence of gravity. Sample stratification can lead to changes in concentration gradients, cell precipitation, and uneven reagent distribution, thus seriously affecting the accuracy and reliability of subsequent test results.

[0003] To avoid stratification, existing technologies typically employ two methods: one is to store the sample statically in a dedicated storage device (such as a refrigerator or freezer) and then transfer it to a separate shaker or vortex mixer for mixing before use; the other is to use a simple portable sample box, which only has the function of heat preservation or fixation and cannot perform mixing operations during storage.

[0004] The first method has significant drawbacks: the frequent transfer of samples between storage and mixing equipment is not only cumbersome and inefficient, but also increases the risk of sample labeling errors, leakage, and cross-contamination. More importantly, during the time between removing the sample from the storage device and mixing it, the sample is actually still in a static state and has already undergone varying degrees of stratification, affecting the accuracy of the analysis. The second method completely fails to solve the stratification problem.

[0005] Therefore, there is an urgent need in the field for an integrated storage device that can dynamically and proactively prevent stratification of samples throughout their entire storage and transportation cycle. Summary of the Invention

[0006] This application provides a magnetically driven oscillating thermostatic chamber for storing transported samples, thereby addressing at least the problem in related technologies of the lack of integrated storage devices that dynamically and proactively prevent stratification of samples throughout the entire storage and transportation cycle.

[0007] According to an embodiment of this application, a magnetic drive oscillation constant temperature chamber for transporter storage is provided, including a chamber body, a magnetic drive mechanism, an oscillation mechanism and a control system; The box body is composed of an upper box body and a lower box body hinged together, and both the upper and lower box bodies are equipped with heat-insulating linings; The magnetic drive mechanism is located inside the lower housing and includes a magnetic push plate assembly and a magnetic tooth assembly. The magnetic push plate assembly includes a movable magnetic strip push plate and a first magnetic strip array disposed thereunder. The magnetic tooth assembly includes a fixed magnetic array plate and a second magnetic strip array disposed thereunder. The corresponding magnetic poles of the first magnetic strip array and the second magnetic strip array are arranged opposite each other with the same pole. The magnetic push plate assembly is connected to the electromagnet via a transmission mechanism. The oscillation mechanism is a shaking table assembly disposed inside the lower housing; The control system is used to control the on / off state of the electromagnet and the start / stop of the oscillation mechanism.

[0008] Preferably, the transmission mechanism is a swing arm scissor mechanism.

[0009] Preferably, the upper housing is provided with a battery, a battery circuit board, and contact probes; the lower housing is provided with contacts corresponding to the positions of the contact probes on the upper housing; when the upper and lower housings are combined, the contact probes are connected to the contacts to supply power to the electromagnet.

[0010] Preferably, the magnetic push plate assembly is located on the left or right side of the magnetic tooth assembly.

[0011] Preferably, the shaker assembly includes a drive shaft, the lower end of which is connected to the magnetic array disk of the magnetic gear assembly via a low-temperature self-lubricating composite bearing and driven to rotate by the drive shaft; at least one eccentric wheel is fixed to the drive shaft; a turntable seat cooperates with the eccentric wheel to convert the eccentric rotational motion into horizontal oscillation; an eccentric tray is fixedly installed above the turntable seat; a tray lower plate is connected to the eccentric tray via multiple tray support rods; the eccentric tray is provided with a circular hole with the same diameter as the migration tube orifice for accommodating the migration tube.

[0012] Preferably, the upper and lower housing shells are made of aluminum alloy with a vacuum structure.

[0013] Preferably, the lower box includes a lower box liner, and the lower box liner is provided with at least one ice box partition.

[0014] This invention provides a magnetically driven oscillating thermostatic chamber for storing transported samples, comprising a chamber body, a magnetic drive mechanism, an oscillation mechanism, and a control system. The chamber body is constructed by hinged upper and lower chamber bodies, both of which are lined with heat-insulating inner linings. The magnetic drive mechanism is located inside the lower chamber body and includes a magnetic pusher plate assembly and a magnetic tooth assembly. The magnetic pusher plate assembly includes a movable magnetic strip pusher plate and a first magnetic strip array disposed below it. The magnetic tooth assembly includes a fixed magnetic array plate and a second magnetic strip array disposed below it. The corresponding magnetic poles of the first and second magnetic strip arrays are arranged with the same poles facing each other. The magnetic pusher plate assembly is connected to an electromagnet via a transmission mechanism. The oscillation mechanism is a shaker assembly located inside the lower chamber body. The control system controls the on / off state of the electromagnet and the start / stop of the oscillation mechanism. The shaker is directly driven by the magnetic tooth assembly to oscillate, which can actively prevent sample stratification throughout the storage process. The eccentric tray features circular holes that match the test tubes, enabling direct, orderly placement and precise positioning. Non-contact drive is achieved using the repulsive force between like-pole magnetic strips, stably pressing and fixing the transporter. Force transmission is uniform and wear-free, providing reliable protection during oscillation and transportation. The functions of constant temperature storage and active oscillation are highly integrated into a single enclosure. Automated operation—"power on and oscillate immediately upon closing the lid"—is achieved through upper and lower enclosure contact points, simplifying the process and improving safety. The enclosure shell uses an aluminum alloy vacuum structure, combined with an internal heat-insulating lining, forming a highly efficient insulation system that maintains a low-temperature environment inside the enclosure for extended periods. The magnetic drive mechanism and oscillation mechanism share the same power source, resulting in a compact structure. Ice box partitions in the lower enclosure lining facilitate modular placement and management of ice boxes, improving space utilization and practicality. Attached Figure Description

[0027] Preferably, the upper housing 1 is provided with a battery 1-3, a battery circuit board 1-4, and a contact probe 1-10; the lower housing 2 is provided with a contact 2-3 corresponding to the position of the contact probe 1-10 of the upper housing; when the upper and lower housings are combined, the contact probe 1-10 is connected to the contact 2-3 to supply power to the electromagnet 6.

[0028] Preferably, the magnetic push plate assembly 5 is located on the left or right side of the magnetic tooth assembly 4.

[0029] Preferably, the shaker assembly 7 includes a drive shaft 7-5, the lower end of which is connected to the magnetic array disk 4-1 of the magnetic gear assembly 4 via a low-temperature self-lubricating composite bearing 7-7 and driven to rotate by it; at least one eccentric wheel 7-3 is fixed on the drive shaft 7-5; a turntable seat 7-6 cooperates with the eccentric wheel 7-3 to convert the eccentric rotational motion into horizontal oscillation; an eccentric tray 7-11 is fixedly installed above the turntable seat 7-6; a tray lower plate 7-8 is connected to the eccentric tray 7-11 via multiple tray support rods 7-9; the eccentric tray 7-11 is provided with a circular hole with the same diameter as the migration tube, for accommodating the migration tube.

Eccentric wheel 7-3: Fixed on the drive shaft 7-5, at least one in number (two in this embodiment).

[0033] Working principle: The user inserts the migration tube into the corresponding round hole in the eccentric tray 7-11 and places the ice box in the ice box partition 3 of the lower shell liner 2-2, then closes the box. At the moment the box closes, the contact probe 1-10 of the upper box 1 connects with the contact 2-3 of the lower box 2, and the circuit is completed. Immediately, the electromagnet 6 is powered, and it actuates, driving the magnetic push plate assembly 5 towards the magnetic tooth assembly 4 via the swing arm scissor motion mechanism composed of the electromagnet link 2-7, the swing arm 2-9, and the scissor-type rotating seat 2-6. Because the first magnetic strip array 5-2 and the second magnetic strip array 4-2 are opposite each other with the same poles, a strong magnetic repulsion force is generated. Simultaneously, the magnetic array disk 4-1 of the magnetic tooth assembly 4 begins to rotate, and the power is transmitted to the shaking table assembly 7 via the transmission shaft 7-5. The eccentric wheel 7-3 rotates accordingly, converting the eccentric rotational motion into regular horizontal oscillations via the turntable seat 7-6. This ultimately drives the eccentric tray 7-11 and the test tubes fixed on it to oscillate together, achieving uniform mixing of the samples and actively preventing stratification. Throughout the process, the vacuum outer shell of the chamber and the internal heat-insulating linings 1-9 and 2-2 together constitute a highly efficient insulation system, which, together with the ice box, can maintain the set low-temperature environment inside the chamber for an extended period.
