Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a glass slide heating device. Background Technology
[0002] FISH (fluorescence in situ hybridization) is a technique used in the biomedical field to suppress the chromosomal localization of genes or sequences, and it plays a significant role in the qualitative and quantitative integration and expression of genes.
[0003] Each step of the FISH pretreatment process requires heating the slides to provide sufficient reaction temperature. However, there are several existing methods for heating slides. One method involves heating the flat slides using a flat-laying oven. This method results in more uniform heating of the slides, but because the slides are relatively thin, placing and removing them is difficult and inconvenient. Another method involves heating the slides by arranging them in a louvered pattern or by placing them at an angle on a drying rod. Both of these methods result in low stability of the slides, making them prone to tilting due to external vibrations. Furthermore, the drying rod method can lead to uneven heating.

The sliding cover is slidably installed on the top of the glass slide loading frame to cover and shield the top of the glass slides.
[0011] Preferably, the insertion direction of the glass slide is parallel to the length direction of the glass slide, and the arrangement direction of the glass slide is parallel to the width direction of the glass slide.
[0012] Preferably, the slide loading rack includes a main body plate and limiting posts arranged at intervals on the same side of the main body plate.

[0031] See Figure 1-7 As shown in the figure, as an embodiment of the present invention, a slide heating device is provided for providing heating and cooling functions for the preheating and heat preservation stage of sample processing before pathological analysis (i.e., fluorescence in situ hybridization (FISH) detection pretreatment). The slide heating device includes a heating module with a receiving groove 12 and a slide loading assembly detachably installed in the receiving groove 12. The slide loading assembly is used for the slide 1 to be laid flat and inserted side by side on it. A heat transfer medium is injected into the receiving groove 12. The heating module is used to heat the heat transfer medium in the receiving groove 12 to heat the slide 1. Specifically, the heat transfer medium is water. An inverted conical joint 11 communicating with the receiving groove 12 is installed on the heating plate 3. The inverted conical joint 11 is used to connect an external water pipe to inject water into the receiving groove 12 or to drain water from the receiving groove 12. In this technical solution, the glass slide 1 is laid flat and inserted side by side on the glass slide loading assembly, and then the glass slide 1 and the glass slide loading assembly are installed together in the receiving groove 12 of the heating module. The heating module heats the water in the receiving groove 12, and thus heats the glass slide 1 by water bath heating. The glass slide 1 is heated more evenly, and the placement and removal of the glass slide 1 is simpler and faster. In addition, the placement stability of the glass slide 1 is higher, avoiding the problem of the glass slide 1 tilting due to external vibration.
[0032] In this embodiment, the heating module includes a heating plate 3 and a sealing plate 4 and a silicone heating film 2 respectively installed on opposite sides of the heating plate 3. Specifically, an installation groove is formed on the side of the heating plate 3 away from the sealing plate 4. The silicone heating film 2 is bonded and fixed to the installation groove. The sealing plate 4 is covered on one side of the heating plate 3 and then locked and fixed by screws. A receiving groove 12 is formed between the heating plate 3 and the sealing plate 4. The silicone heating film 2 is heated by electricity and then the heat is transferred to the water in the receiving groove 12 through the heating plate 3 to achieve water bath heating of the glass slide 1. The receiving groove 12 is a flat groove with an open top. The glass slide loading assembly is inserted into the receiving groove 12 from top to bottom. The structural design of the receiving groove 12 maximizes the space compression of the heating module. The combined use of the heating module and the glass slide loading rack 6 reduces the amount of water required for a single water inlet and outlet, thereby reducing the amount of water used and reducing water loss.
[0033] In this embodiment, the sealing plate 4 is an acrylic sealing plate. A cooling fan (not fixed to the heating module, so it is not shown in the drawing) is also provided on one side of the heating module to dissipate heat and cool down the glass slide heating device. The acrylic sealing plate makes it difficult to conduct heat, thereby reducing the amount of heat that needs to be discharged when the glass slide heating device dissipates heat.
[0034] In this embodiment, a silicone heat insulation pad 13 is clamped between the heating plate 3 and the sealing plate 4, so that the heat of the heating plate 3 can be concentrated and transferred to the water in the receiving tank 12, avoiding excessive heat transfer to the sealing plate 4, and ensuring efficient heating of the glass slide 1. A support plate 5 is installed on the top of the heating plate 3, so that the glass slide heating device can be fixedly placed in a specific position by the support plate 5.
[0035] In this embodiment, a glass slide 1 is also included. The glass slide loading assembly includes a glass slide loading frame 6 and a sliding cover 7. The glass slide 1 is laid flat and inserted side by side on the glass slide loading frame 6, and the tops of the glass slide loading frame 6 and the glass slide 1 respectively protrude from the outside of the receiving groove 12. The sliding cover 7 is slidably installed on the top of the glass slide loading frame 6 to cover and shield the top of the glass slide 1, thereby reducing the evaporation of water in the receiving groove 12 and preventing external cold air from entering the receiving groove 12, thus ensuring the heat preservation effect of the glass slide 1.
[0036] In this embodiment, the insertion direction of the glass slide 1 is parallel to the length direction of the glass slide 1, and the arrangement direction of the glass slide 1 is parallel to the width direction of the glass slide 1. This ensures that the glass slide 1 is heated more evenly, further improves the convenience of placing and removing the glass slide 1, and makes the placement stability of the glass slide 1 higher, avoiding the problem of the glass slide 1 tilting due to external vibration.
[0037] In this embodiment, the slide loading rack 6 includes a main body plate 61 and limiting posts 62 arranged at intervals on the same side of the main body plate 61. A plurality of limiting slots 31 are provided on the inner side wall of the heating plate 3 of the heating module on one side of the receiving slot 12. The limiting slots 31 and the limiting posts 62 are matched to limit each other, thereby ensuring the installation stability of the slide loading rack 6 in the heating module. The limiting posts 62 are provided with sliding grooves 63 that slide with the slide 1. The bottom side of the main body plate 61 is provided with a supporting protrusion 64 for supporting the slide 1. A slide loading slot 65 is formed between two adjacent limiting posts 62, the supporting protrusion 64 and the main body plate 61. The slide 1 is inserted into the slide loading slot 65. This arrangement can improve the placement stability of the slide 1 on the slide loading rack 6, and one side of the slide 1 is in direct contact with the water, which improves the heating efficiency.
[0038] In this embodiment, the top of the main body plate 61 extends horizontally in opposite directions to form a sliding extraction part 66. The interior of the sliding cover 7 has a glass slide end receiving groove 9 and a T-shaped sliding groove 10 that are connected vertically. The sliding extraction part 66 and the T-shaped sliding groove 10 slide and engage, thereby allowing the sliding cover 7 to slide and be installed on the top of the glass slide loading rack 6, so that the top of the glass slide 1 is located in the glass slide end receiving groove 9. One end of the sliding direction of the sliding cover 7 is an open structure, and the other end is a sealed structure. This structure ensures the installation stability of the sliding cover 7 on the glass slide loading rack 6, while ensuring the heat preservation effect of the glass slide 1. The surface of the sliding cover 7 is provided with friction protrusions 8 to facilitate stable picking up by the user.
[0039] The working process of the glass slide heating device in this embodiment is as follows:
[0040] First, multiple glass slides 1 are laid flat and inserted side-by-side into the slide loading slots 65 of the slide loading rack 6. Then, the sliding cover 7 is slid and installed on the top of the slide loading rack 6 to cover and shield the top of the glass slides 1. Next, the assembled slide loading assembly is lifted and inserted into the receiving slot 12 of the heating module. Purified water is injected through the hose connected to the inverted conical connector 11 at the bottom of the heating plate 3. The silicone heating film 2 is energized and heated, allowing heat to be transferred through the heating block to the water in the receiving slot 12, thus achieving water bath heating of the glass slides 1. The thermistor of the silicone heating film 2 is used to achieve... The temperature is fed back in real time. Once the required temperature is reached, the temperature control element of the silicone heating film 2 stops heating. The cooling fan is responsible for temperature control. Hot air is exhausted from the equipment through the heat dissipation duct reserved on the external instrument. When the heating step is over, water is drained through the inverted conical joint 11 at the bottom of the heating plate 3, which can quickly remove some of the heat. The above technical solution achieves temperature control and heat preservation of the glass slide. The glass slide 1 is heated more evenly, and the placement and removal of the glass slide 1 is simpler and faster. The placement stability of the glass slide 1 is also higher, avoiding the problem of the glass slide 1 tilting due to external vibration.
