Description

Technical Field

[0001] This utility model relates to the field of medical laboratory equipment technology, specifically to an optical microscope immersion oil recovery device. Background Technology

[0002] In the daily work of a cytogenetics laboratory, the observation of metaphase cells is an important task, usually accomplished using a microscope. When using an oil immersion microscope to magnify images, the immersion oil plays a crucial role as a key optical medium. It allows light to pass directly through the medium after passing the slide into the objective lens, avoiding light refraction and thus improving the microscope's resolution and illumination. Traditional cedar oil microscopy and imaging rely on manual operation. However, with the widespread application of artificial intelligence technology in various fields, the inefficiency of this manual method has become increasingly apparent, making it difficult to meet the needs of daily work in medical laboratories.

[0003] To improve work efficiency, medical laboratories have introduced computer-controlled fully automated chromosome scanning systems. These systems feature automatic chromosome scanning, automatic immersion oil application, and automatic image acquisition, enabling one-stop operation and facilitating subsequent analysis. However, the immersion oils used in these automated systems are all imported, resulting in high prices and large consumption. Furthermore, laboratories typically absorb immersion oil by using baffles on slide holders or paper materials in slide boxes, leading to significant waste. Therefore, this application provides an optical microscope immersion oil recovery device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an optical microscope immersion oil recovery device, which solves the problem of significant waste of immersion oil caused by the existing technology that typically uses baffle paper on the slide holder or paper material placed inside the slide box for absorption.

[0005] The optical microscope immersion oil recovery device of this utility model includes a support bracket and a slide fixing frame disposed inside the support bracket. The bottom of the slide fixing frame is provided with a collection component for collecting the target object on the slide.

[0006] The slide fixing frame includes a fixing bracket, and sleeves are provided at both ends of the fixing bracket for adjusting the support width of the fixing bracket;

[0007] The inner side of the fixing frame is provided with a limiting strip, which is adapted to the glass slide. A limiting area is formed between two limiting strips for installing the glass slide.

[0008] As a further improvement of this utility model, a set of symmetrically arranged positioning cylinders are provided on the outer side of the fixing frame, and a telescopic rod is installed on the inner side of the positioning cylinder, with one end of the telescopic rod abutting against the inner wall of the bracket.

[0009] As a further improvement of this utility model, the collection component includes a guide plate disposed below the bracket, the bottom of the guide plate having a discharge port, and a collection bottle disposed at the bottom of the discharge port.

[0010] As a further improvement of this utility model, the bracket includes a frame and a support rod, the bottom of which is adapted to the support rod for supporting the frame.

[0011] As a further improvement of this utility model, the fixing frame includes a body, and a groove is provided on the inner side of the body. Vibration components arranged in a linear array are provided on the inner side of the groove.

[0012] As a further improvement of this utility model, a locking block is provided on the side of the vibration component near the limiting strip for fixing the limiting strip.

[0013] As a further improvement of this utility model, the limiting strip includes a strip body, and a positioning groove is provided on the side of the strip body near the vibration component. The positioning groove is adapted to the locking block on the vibration component.

[0014] As a further improvement of this utility model, a slot is provided on the side of the two strips that are close to each other, and the slot abuts against the outer side of the glass slide.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a vibration component within the groove of the fixed frame to accelerate the flow of immersion oil from the glass slide, reducing immersion oil residue. Combined with the inclined design of the guide plate and the rationally arranged discharge port, it can efficiently guide the immersion oil to the collection bottle, greatly improving the recovery efficiency of immersion oil and reducing waste. Furthermore, the sleeves at both ends of the fixed frame can adjust the support width, and the telescopic rod inside the positioning cylinder can adjust the length, allowing the device to adapt to glass slides of different sizes and brackets of different specifications, enhancing the versatility and applicability of the device.

[0017] The vibration assembly, with its adjustable vibration frequency and amplitude, can adapt to the recovery needs of immersion oils of different viscosities. The positioning cylinder and telescopic rod ensure the slide fixing frame is securely installed within the bracket, preventing shaking or displacement. The entire device has a simple structural design; operators only need to adjust the telescopic rod and place the slides to complete the immersion oil recovery work, reducing operational difficulty and labor intensity. The control switch of the vibration assembly allows for convenient adjustment of the vibration frequency and amplitude, enabling flexible operation according to actual conditions, effectively recovering immersion oil, improving immersion oil utilization, reducing the consumption of imported immersion oil, and lowering laboratory costs related to immersion oil. The rubber pads on the inner wall of the slot protect the slides from scratches, extending their lifespan and further reducing laboratory costs. Attached Figure Description

[0030] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0031] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] Please see Figure 1-5 In cytogenetics laboratories, microscopes are frequently used to observe cells in metaphase. When using oil immersion to magnify images, immersion oil is often used as an optical medium, allowing light to pass directly through the medium to the objective lens without refraction after passing through the slide, thereby improving the microscope's resolution and illumination. With the widespread application of artificial intelligence, the inefficiency of manual cedar oil microscopy and imaging can no longer meet daily work needs. Medical laboratories have begun to adopt computer-automated chromosome scanning systems, which can automatically complete chromosome scanning, automatically add immersion oil to images, and automatically acquire photographs for further analysis in one stop. However, fully automated scanning systems use imported immersion oil, which is expensive and consumed in large quantities. The immersion oil on the slide is wasted by directly absorbing it with the baffle paper on the slide holder or the paper material in the slide box. Based on this, embodiments of this application provide an optical microscope immersion oil recovery device, including a support bracket 1 and a slide fixing frame 2 disposed inside the support bracket 1. A collection component 3 is disposed at the bottom of the slide fixing frame 2 for collecting the target object on the slide.

[0033] The slide fixing frame 2 includes a fixing frame 24, and sleeves 22 are provided at both ends of the fixing frame 24 for adjusting the support width of the fixing frame 24;

[0034] The inner side of the mounting bracket 24 is provided with a limiting strip 25, which is adapted to the glass slide. A limiting area 26 is formed between the two limiting strips 25 for the installation of the glass slide.

[0035] The bracket 1 can be made of metal, such as aluminum alloy, which has a certain strength and corrosion resistance. To ensure the stability of the entire device when placed, anti-slip pads can be installed on both sides of the bracket 1 to prevent the device from sliding during operation.

[0036] The mounting bracket 24 is also made of aluminum alloy, and its surface is smoothed to reduce friction with the glass slide. The length and width of the mounting bracket 24 can be designed according to the size of common glass slides, generally 15-20 cm in length and 5-8 cm in width.

[0037] The sleeve 22 is made of plastic and has internal threads. By rotating the sleeve 22 or by sliding it, the two ends of the fixing bracket 24 can be extended or retracted to adjust the support width. The sleeve 22 can be marked with scales to facilitate operators to accurately adjust to the appropriate width.

[0038] The limiting strip 25 is made of rubber and has a certain degree of elasticity. Its height is 2-3 mm and its width is 1-2 mm. The rubber material better protects the glass slide and prevents damage during installation.

[0039] The collection assembly 3 includes a collection trough and a collection bottle 33. The collection trough is installed at the bottom of the slide fixing frame 2 and is made of transparent plastic to facilitate observation of the immersion oil collection. The collection trough is funnel-shaped and its bottom is connected to the collection bottle 33 via a pipe. The collection bottle 33 is made of glass and has a certain capacity, such as 50-100 ml. The bottle has graduations to facilitate recording the amount of immersion oil recovered.

[0040] Operating procedures:

[0041] First, based on the size of the glass slide, the support width of the fixing frame 24 is adjusted by rotating the sleeve 22 so that the distance between the two limiting strips 25 is just enough to accommodate the glass slide.

[0042] Carefully place the slide that needs to have its immersion oil recycled into the limiting area 26, ensuring that the slide is placed stably.

[0043] The immersion oil will flow naturally down the glass slide into the collection trough at the bottom, and then flow into collection bottle 33 through the pipe.

[0044] When the mirror oil in collection bottle 33 reaches a certain amount, close the valve on the pipeline and remove collection bottle 33 for further processing.

[0045] The specialized collection component 3 effectively collects immersion oil from glass slides, preventing waste, improving the recycling rate of immersion oil, and reducing laboratory operating costs.

[0046] The sleeves 22 at both ends of the fixing frame 24 can adjust the support width, so that the device can be adapted to glass slides of different sizes, enhancing the versatility and applicability of the device.

[0047] The rubber limiting strip 25 on the inner side of the fixing bracket 24 can effectively prevent scratches and damage to the glass slide while installing and positioning it, thus extending the service life of the glass slide.

[0048] Compared with existing technologies, the entire device has a simple structural design. Operators only need to make simple adjustments and placement operations to complete the recovery of mirror oil, which reduces the difficulty of operation and labor intensity.

[0049] Furthermore, the collection tank is made of transparent material, and the collection bottle 33 is marked with graduations, which makes it convenient for operators to observe the collection of immersion oil and record the amount recovered, which helps the laboratory to conduct cost accounting and resource management.

[0050] In one possible implementation, a set of symmetrically arranged positioning cylinders 23 are provided on the outer side of the fixing frame 24, and a telescopic rod 21 is installed on the inner side of the positioning cylinder 23, with one end of the telescopic rod 21 abutting against the inner wall of the bracket 1.

[0051] The collection component 3 includes a guide plate 32 disposed below the bracket 1, with a discharge port 31 at the bottom of the guide plate 32 and a collection bottle 33 disposed at the bottom of the discharge port 31.

[0052] The bracket 1 includes a frame 11 and a support rod 12. The bottom of the frame 11 is adapted to the support rod 12 to support the frame 11.

[0053] The positioning cylinder 23 is made of high-strength plastic material, such as polycarbonate, which has good wear resistance and impact resistance. Its inner diameter is slightly larger than the outer diameter of the telescopic rod 21, ensuring that the telescopic rod 21 can slide flexibly inside the positioning cylinder 23. Scale markings can be set on the outside of the positioning cylinder 23 to facilitate users in accurately controlling the extension length of the telescopic rod 21.

[0054] The telescopic rod 21 is made of stainless steel and the surface is polished to reduce friction with the inner wall of the positioning cylinder 23. A rubber buffer pad can be installed at the end of the telescopic rod 21 that abuts against the inner wall of the bracket 1, which can prevent scratches on the inner wall of the bracket 1 and increase friction to make the fixing frame more stable.

[0055] The guide plate 32 is made of metal, such as aluminum alloy, and its surface is smoothed to reduce the residue of mirror oil on the guide plate 32. The guide plate 32 is designed to be inclined at an angle of 15°-30° to ensure that the mirror oil can flow smoothly to the outlet 31.

[0056] The outlet 31 can also be equipped with a removable filter screen to filter impurities in the immersion oil. The filter screen is made of stainless steel, and the mesh size is determined according to the size of the impurities that may exist in the immersion oil.

[0057] Collection bottle 33 is made of transparent glass and has volume markings on the body. A sealing cap is fitted at the bottle opening to prevent evaporation and leakage of the immersion oil.

[0058] The frame 11 of bracket 1 is made of high-strength plastic or metal, such as polypropylene or stainless steel. The frame 11 is designed as a frame structure, which ensures strength while reducing weight.

[0059] The support rod 12 is made of solid metal, such as carbon steel, with a rust-proof surface. Rubber feet are installed at the bottom of the support rod 12 to increase friction with the ground and improve the stability of the device.

[0060] Operating procedures:

[0061] First, adjust the extension length of the telescopic rod 21 inside the positioning cylinder 23 as needed, and install the glass slide fixing frame 2 inside the bracket 1 so that the telescopic rod 21 is in close contact with the inner wall of the bracket 1.

[0062] A glass slide with immersion oil is placed in the slide fixing frame 2. The immersion oil flows down the glass slide and drips onto the guide plate 32. It is then guided by the guide plate 32 to the outlet 31, filtered through the filter screen, and flows into the collection bottle 33.

[0063] Maintenance process:

[0064] Clean the guide plate 32 and the outlet 31 regularly to prevent varnish residue and impurities from clogging the filter screen. Replace the filter screen regularly to ensure filtration effect.

[0065] Check the fit between the telescopic rod 21 and the positioning cylinder 23, and replace them promptly if there is any wear.

[0066] Compared with existing technologies, the positioning cylinder 23 and telescopic rod 21 enable the slide fixing frame 2 to be stably installed in the bracket 1, avoiding shaking or displacement during use and ensuring the stability and reliability of the immersion oil recovery process.

[0067] The inclined design of the guide plate 32 and the reasonable layout of the discharge port 31 can efficiently guide the luminous oil to the collection bottle 33, reduce the residue and waste of luminous oil, and improve the luminous oil recovery rate.

[0068] The filter screen installed at the discharge port 31 can effectively filter impurities in the immersion oil, improve the purity of the recovered immersion oil, and facilitate the secondary use of the immersion oil.

[0069] The telescopic rod 21 is adjustable in length, allowing the device to adapt to different specifications of brackets 1 and usage requirements, thus enhancing the device's versatility.

[0070] Each component has a relatively independent structure, making it easy to disassemble and clean. For example, the filter screen can be replaced regularly, and the guide plate 32 and the discharge port 31 can be cleaned at any time, reducing the maintenance difficulty and cost of the device.

[0071] The frame 11 of the bracket 1 is compatible with the support rod 12, and the bottom of the support rod 12 has rubber feet, which ensures the stability of the entire device and reduces problems such as immersion oil spillage caused by device shaking.

[0072] In one possible implementation, the mounting bracket 24 includes a body 242, the inner side of which is provided with a groove 241, and the inner side of the groove 241 is provided with vibration components 244 arranged in a linear array.

[0073] A locking block 243 is provided on the side of the vibration assembly 244 near the limiting strip 25 for fixing the limiting strip 25.

[0074] The limiting strip 25 includes a strip body 251, and a positioning groove 252 is provided on the side of the strip body 251 near the vibration component 244. The positioning groove 252 is adapted to the locking block 243 on the vibration component 244.

[0075] A slot 253 is provided on one side of the two strips 251 that are close to each other, and the slot 253 abuts against the outer side of the glass slide.

[0076] Vibration assembly 244 employs a small electromagnetic vibrator with a plastic housing that provides excellent insulation and corrosion resistance. The electromagnetic vibrator is powered by an external power source and its vibration frequency and amplitude are adjustable to meet various spectral oil recovery needs.

[0077] The locking block 243 is made of rubber and has a certain degree of elasticity, which can better cooperate with the positioning groove 252, provide a certain buffer when installing and removing the limit strip 25, and enhance the fixing effect. The strip body 251 is made of aluminum alloy to ensure a tight fit with the locking block 243.

[0078] A soft rubber pad is attached to the inner wall of the slot 253, which can protect the surface of the slide from scratches and increase the friction with the slide, thereby further improving the stability of the slide.

[0079] The body 242 is made of high-strength engineering plastics, such as polyamide (nylon), which has good mechanical properties and chemical corrosion resistance. The depth and width of the groove 241 are matched according to the size of the vibration assembly 244 to ensure the vibration assembly 244 is securely installed.

[0080] Installation process:

[0081] First, install the vibration assembly 244 in the groove 241 of the body 242 of the fixing frame 24 in a linear array, and then connect the power supply line.

[0082] Align the positioning groove 252 of the limiting strip 25 with the locking block 243 on the vibration assembly 244, and press gently to firmly fix the limiting strip 25 on the fixing frame 24.

[0083] Slowly insert the slide along the slot 253, ensuring that the slide is in close contact with the slot 253.

[0084] Control process:

[0085] Depending on the viscosity of the immersion oil and its distribution on the slide, an appropriate vibration frequency and amplitude can be selected by adjusting the control switch of the electromagnetic vibrator. For example, for immersion oil with higher viscosity, the vibration frequency and amplitude can be appropriately increased.

[0086] The vibration component 244 can make the immersion oil on the slide flow down more quickly through vibration, reduce the residue of immersion oil on the slide, thereby improving the recovery efficiency of immersion oil and reducing the waste of immersion oil.

[0087] The limiting strip 25 is fixed to the fixing frame 24 by the cooperation of the locking block 243 and the positioning groove 252. This connection method not only ensures the firmness of the installation of the limiting strip 25, but also facilitates the disassembly and replacement of the limiting strip 25, making the maintenance and cleaning of the device convenient. The rubber pad on the inner wall of the locking groove 253 can effectively prevent scratches on the surface of the glass slide during installation and use, extend the service life of the glass slide, and reduce the use cost of the laboratory.

[0088] The vibration frequency and amplitude of the vibration component 244 are adjustable, and can be flexibly adjusted according to the characteristics of different immersion oils and the actual recycling situation, which improves the applicability and versatility of the device. The structural design of the fixed frame 24 body 242, the vibration component 244 and the limiting strip 25 cooperate with each other to make the entire glass slide fixing frame 2 structure compact and stable, providing reliable support for immersion oil recycling work.
