Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary equipment and relates to embedding machines, specifically a rapid temperature-controlled embedding machine. Background Technology

[0002] An embedding machine, also known as a biological tissue embedding machine or paraffin embedding machine, is a Class I clinical laboratory instrument, classified as a sample processing instrument for pathological analysis. This device uses paraffin embedding technology to solidify biological tissue specimens into paraffin blocks, providing a basic sample for subsequent microscopic sectioning. It is mainly used in the fields of pathological diagnosis, forensic research, and teaching.

[0003] For example, a constant temperature ice water stage for an embedding machine, disclosed in CN214538900U, includes a main body. The main body is equipped with a refrigeration system, which includes a compressor, a condenser, an evaporator, a cooling fan, a dryer filter, and a capillary tube. The main body is equipped with an ice water tank for holding ice water. The evaporator is located at the bottom of the ice water tank, and a heater is also provided at the bottom of the ice water tank. A mounting hole is provided on one side wall of the ice water tank, and a temperature measuring device is installed in the mounting hole. The fan speed is adjustable.

[0004] The aforementioned embedding machine is a relatively common type. When in use, the embedding box containing the paraffin liquid and the specimen is placed on the cold stage. At this time, the low temperature on the cold stage can accelerate the solidification of the paraffin. However, during the operation, since the operator needs to move the embedding box, there is a possibility that the paraffin liquid will drip onto the cold stage and solidify. After using the embedding machine, the solidified paraffin on the cold stage is difficult to clean, affecting the flatness of the cold stage surface. Utility Model Content

[0005] This invention provides a rapid temperature-controlled embedding machine that can thoroughly remove solidified paraffin wax from the surface of a cold table.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a rapid temperature-controlled embedding machine, including a frame and a cold table fixed on the frame, characterized in that a scraper is slidably connected above the cold table on the frame, and a scraper that abuts against the surface of the cold table is fixedly connected on the scraper. There is an angle between the scraper and the cold table, and the angle is less than 90°. When the embedding machine is in use, the scraper is separated from the cold table and the scraper is attached to the frame.

[0007] A further preferred embodiment of this utility model is that the scraper is arranged at an angle, with the section of the scraper near the scraper frame being higher than the section near the cold table.

[0008] A further preferred embodiment of this utility model is as follows: a material box is fixedly connected to the scraper, and one end of the scraper abuts against the opening of the material box.

[0009] A further preferred embodiment of this utility model is as follows: a groove is provided on the frame, and when the scraper is in contact with the frame, the material box is embedded in the groove.

[0010] A further preferred embodiment of this utility model is: a magnetic sheet that can attract the machine frame is fixedly connected to the side wall of the material box near the groove.

[0011] A further preferred embodiment of this utility model is as follows: the frame is provided with sliding grooves on both sides of the cold table, and the bottom end of the scraper is fixedly connected to a slider that slides within the sliding groove.

[0012] A further preferred embodiment of this utility model is as follows: a baffle is hinged inside the material box via a pin, and there is an opening between the baffle and the bottom surface of the material box to facilitate the entry of paraffin wax.

[0013] A further preferred embodiment of this utility model is as follows: a torsion spring is sleeved on the pin shaft to facilitate the rotation of the baffle. When the opening becomes larger, the baffle rotates outward and the torsion spring deforms.

[0014] A further preferred technical solution of this utility model is: a defrosting solenoid valve is provided inside the machine body.

[0015] Compared with the prior art, this utility model includes a frame and a cold table fixed on the frame. A scraper is slidably connected to the frame above the cold table. A scraper blade is fixedly connected to the scraper blade and abuts against the surface of the cold table. There is an angle between the scraper blade and the cold table, which is less than 90°. When the embedding machine is in use, the scraper blade is separated from the cold table and the scraper blade is attached to the frame. Therefore, when it is necessary to clean the solidified paraffin wax on the cold table, the sliding scraper blade makes the scraper blade abut against the surface of the cold table. At this time, as the scraper blade slides, the scraper blade scrapes off the solidified and raised paraffin wax on the surface of the cold table, thereby effectively avoiding the occurrence of unevenness on the surface of the cold table and effectively improving the uniformity of condensation. The operation is simple, convenient and easy to implement. Attached Figure Description

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0021] like Figures 1-5 As shown, a rapid temperature-controlled embedding machine includes a frame 1 and a cold table 2 fixed on the frame 1. A scraper 3 is slidably connected to the frame 1 above the cold table 2. A scraper 4 is fixedly connected to the scraper 3 and abuts against the surface of the cold table 2. There is an angle 10 between the scraper 4 and the cold table 2, which is less than 90°. When the embedding machine is in use, the scraper 4 is separated from the cold table 2 and the scraper 3 is attached to the frame 1.

[0022] like Figures 1-5 As shown, when scraping off the solidified paraffin on the surface of the cold table 2, the scraper 3 is moved. As the scraper 3 moves, the scraper 4 comes into contact with the surface of the cold table 2. As the scraper 3 moves, the scraper 4 removes the solidified and protruding paraffin on the surface of the cold table 2, thus keeping the cold table 2 clean and ensuring the flatness of the surface of the cold table 2, which facilitates the subsequent placement of the embedding box and the condensation of the paraffin. like Figures 2-4 As shown, the scraper 4 is set at an angle, with the section of the scraper 4 near the scraper frame 3 being higher than the section near the cold table 2. Because the scraper 4 is set at an angle, while scraping off the paraffin wax, the scraped paraffin wax is discharged out of the scraper 4 along the angled scraper 4, thereby avoiding the accumulation of paraffin wax in the front section of the scraper 4 and affecting the scraping effect. This design effectively improves the cleaning effect of the scraper 4.

[0023] like Figures 2-4As shown, the machine body 1 is equipped with a defrosting solenoid valve, which can melt the frost generated on the surface of the paraffin due to low temperature, thereby making it easier for the scraper 4 to remove the paraffin, improving the convenience of dewaxing, and effectively avoiding damage to the surface of the cold table 2 caused by vigorous dewaxing.

[0024] like Figures 2-4 As shown, a material box 5 is fixedly connected to the scraper frame 3, and one end of the scraper 4 abuts against the opening of the material box 5. Therefore, after the scraper 4 scrapes off the paraffin wax, the scraped paraffin wax enters the material box 5 along the obliquely set scraper 4 for collection, which facilitates subsequent centralized cleaning, improves the convenience of cleaning, and can effectively prevent the paraffin wax from scattering and affecting the sliding of the scraper 4, further ensuring the smooth sliding of the scraper frame 3.

[0025] like Figures 2-4 As shown, a baffle 11 is hinged inside the material box 5 via a pin 13. There is an opening 12 between the baffle 11 and the bottom surface of the material box 5 to facilitate the entry of paraffin wax. By setting the baffle 11, when there is a lot of paraffin wax in the material box 5, it can block it to a certain extent, preventing a large amount of paraffin wax from leaking out and making cleaning inconvenient. This design plays a role in limiting the range of paraffin wax movement inside the material box 5, so that the collected paraffin wax can be better located inside the material box 5.

[0026] like Figures 2-4 As shown, a torsion spring 14 is sleeved on the pin 13 to facilitate the rotation of the baffle 11. When the opening becomes larger, the baffle 11 rotates outward and the torsion spring 14 deforms. When it is necessary to clean the paraffin in the material box 5, the baffle 11 is rotated outward through the opening 12. At this time, due to the force, the baffle 11 rotates around the pin 13 and the torsion spring 14 deforms. At the same time, the opening 12 becomes larger, which facilitates the cleaning of the paraffin in the material box 5. like Figures 2-4 As shown, after cleaning is completed, the deformed torsion spring 14 drives the baffle 11 to reset, thereby restoring the opening 12 to its original state, making it easier to collect the paraffin wax again.

[0027] like Figures 2-4 As shown, a groove 7 is provided on the frame 1. When the scraper 3 is attached to the frame 1, the material box 5 is embedded in the groove 7. This design serves to hide the material box 5 when the embedding machine is in use, to prevent the material box 5 from protruding and affecting the use of the cold table 2, and to reduce the footprint of the material box 5.

[0028] like Figures 2-4 As shown, a magnetic sheet 9 that can be attracted to the frame 1 is fixedly connected to the side wall of the material box 5 near the groove 7. This allows the material box 5 to be fixed to the frame 1 when the scraper 3 is not in use, thereby preventing the scraper 3 from shifting when the embedding machine moves or is hit, which would cause the material box 5 to be exposed.

[0029] like Figures 2-4As shown, the frame 1 has sliding grooves 6 on both sides of the cold table 2. The bottom of the scraper 3 is fixedly connected to a slider 8 that slides in the sliding groove 6. By setting the sliding groove 6, the sliding trajectory of the scraper 3 can be restricted, so as to prevent the scraper 3 from shifting left and right during the sliding process, thereby affecting the effect of removing paraffin.

[0030] The above describes a rapid temperature-controlled embedding machine provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
