Description

Technical Field

[0001] This utility model relates to the field of high-magnification oil immersion microscopy imaging technology, specifically, to an oil dripping device for high-magnification oil immersion microscopy imaging. Background Technology

[0002] In high-powered microscopy, oil application is a common technique used to improve microscope resolution and image sharpness. It is particularly important when observing minute biological samples, such as bacteria or internal cellular structures. By filling the space between the objective lens and the sample with oil (usually cedarwood oil or impregnated oil), the numerical aperture is increased, achieving higher resolution. Because oil has a higher refractive index than air, more light passing through it is collected and transmitted to the objective lens, thus enhancing the brightness of the field of view and making the image bright and clear. This technique is especially crucial for observing transparent or translucent samples, as it significantly improves image sharpness, allowing minute structures to be revealed, which is of great significance for scientific research and medical diagnosis.

[0003] An oil-drip apparatus is an automated tool specifically designed for oil-drip operations in microscopes. Its purpose is to improve the accuracy and repeatability of the oil-drip process and reduce human error. The apparatus needs to precisely control the size and placement of the oil droplets to ensure consistency in each drip. Furthermore, it should have an anti-backflow function to prevent oil from flowing back into the tubing, avoiding contamination and waste. Another important function is the ability to flexibly adjust the position of the drip needle to adapt to the observation needs of different samples. Through automation and precise control, the oil-drip apparatus not only improves experimental efficiency but also helps obtain higher-quality microscopic images, playing a crucial role in enhancing the accuracy of scientific research and medical testing.

[0004] However, while existing oil-drip devices have improved the automation of oil dripping to some extent, they still have many shortcomings. For example, patent CN201417338Y discloses a manual oil-drip device for a microscope oil immersion lens. This device uses manual squeezing of the oil bottle to drip oil, which easily introduces air bubbles, affecting the dripping effect and potentially causing contamination. The amount of oil dripped is difficult to control precisely, depending on the squeezing force and the amount of oil. In addition, the fixed position of the oil outlet limits the flexibility of the dripping location. Utility Model Content

[0036] To address the problems existing in the prior art, this invention provides a high-magnification oil immersion microscopy dripping device, aiming to overcome the shortcomings of the prior art. The device employs a metering pump assembly to precisely control the amount of oil extracted, ensuring consistency in the amount of oil dripped each time and achieving quantitative dripping. Through a designed pipeline and one-way valve structure, backflow of oil in the pipeline is effectively prevented, avoiding contamination and waste.

The metering pump 3 is fixedly mounted on a fixing plate 7 of the support adjustment module. The oil dripping needle 4 is fixedly mounted on an adjusting bracket 5 of the support adjustment module through the oil dripping needle retainer 6. The adjusting bracket 5 is used to adjust the position of the oil dripping needle 4. The oil dripping needle 4, the metering pump 3, and the oil storage module are connected in sequence through the oil delivery pipe 2.

[0038] Furthermore, the bracket adjustment module includes: a fixing plate 7, a vertical fixing bracket 10, a horizontal fixing bracket 11, and an adjustment bracket 5. The fixing plate 7 is used to fix the metering pump 3; the fixing brackets 10 and 11 are used to firmly install the oil dripping device on the microscope to ensure that the device remains stable during use; the adjustment bracket 5 is used to realize multi-directional adjustment of the oil dripping and determine the appropriate oil dripping position of the oil dripping needle relative to the slice.

[0039] Furthermore, the oil storage module includes: an oil storage container 1 and a liquid level sensor 8. The oil storage container 1 is used to store the oil required for dripping, providing a stable oil source for the dripping system; the liquid level sensor 8 is used to remind the user to replenish the oil in time, ensuring the continuous operation of the dripping system.

[0040] Furthermore, the oil delivery module includes: a metering pump 3, an oil delivery pipe 2, an oil dripping needle 4, and an oil dripping needle retainer 6. The metering pump 3 is used to precisely control the oil delivery volume, ensuring that the amount of oil dripped each time is consistent and avoiding fluctuations in the amount of oil dripped. The oil delivery pipe 2 is used to deliver the oil from the oil storage module to the oil dripping needle 4, ensuring smooth oil flow and no air bubbles are generated. The oil dripping needle retainer 6 is used to firmly install the oil dripping needle and ensure that the oil dripping needle 4 remains stable during use, preventing the oil dripping position from shifting due to external force. The oil dripping needle 4 is used to accurately drip the oil onto the microscope slide, avoiding splashing and contamination during the oil dripping process.

[0041] Furthermore, the electric control module includes: a function for receiving signals from the liquid level sensor 8 and controlling the operation of the oil dripping system according to a preset program, including the frequency of oil dripping, the amount of oil dripping, and the start and stop of oil dripping;

[0042] Furthermore, the adjusting bracket 5 can be freely adjusted in the XYZ direction, and the vertical fixing bracket 10 and the horizontal fixing bracket 11 are used to fix each module device, and the brackets are connected to each other by fixing clips.

[0043] Furthermore, the oil storage container 1 is transparent and has a scale display showing the oil level, and is connected to the adjustment bracket 5 by bolts; the liquid level sensor 8 is connected to the oil storage container 1 by a snap-fit.

[0044] Furthermore, the metering pump 3 is a high-precision (microliter) unidirectional flow pump, which is connected to the fixing plate 7 by bolts; the oil storage container 1 is connected to the metering pump 3 through the oil delivery pipe 2, and after the metering pump 3 outputs the oil in a metered manner, it is delivered to the oil dripping needle 4 through the oil delivery pipe 2 for dripping; the oil dripping needle retainer 6 is connected to the adjusting bracket 5 by bolts, which can realize the adjustment of the tilt angle;

[0045] Furthermore, the electric control module 9 is used to precisely drive the metering pump and receive feedback signals from the liquid level sensor to achieve closed-loop control and automated operation;

[0046] The following will, in conjunction with the above content, fully describe the usage process of the oil dripping device for high-magnification oil immersion microscopy in this embodiment: Before dripping, adjust the adjusting bracket 5 to ensure the accurate relative position between the oil dripping needle 4 and the slide. Subsequently, the electric control module 11 controls the metering pump 3 to perform precise metering oil dripping. After dripping, the one-way valve of the metering pump 3 is activated to prevent the oil in the oil delivery pipe from dripping due to gravity, thus avoiding oil waste and contamination of the dripping location. At the same time, the pipeline maintains a vacuum state and the pump chamber is compressed by the solenoid valve to effectively prevent the formation of air bubbles. When the oil level in the oil storage container 1 decreases to the specified level, the level sensor 8 triggers a signal to the electric control module 9, issuing an oil level alarm to remind the user to replenish the oil in time and ensure the normal operation of the device.

[0047] This invention achieves high-precision oil dripping from a metering pump by periodically switching the power on and off, and solves the problems of backflow, air bubbles, and low dripping accuracy in microscope oil dripping devices due to issues with the oil delivery pipe and the need for adjusting the position of the dripping needle.
