DETAILED DESCRIPTION

[0028] To facilitate a better understanding of this utility model, the following examples are provided in conjunction with the accompanying drawings. These examples fall within the protection scope of this utility model, but do not limit the protection scope of this utility model.

[0029] Example 1

[0030] A pathological paraffin block sealing device, such as Figures 1-6 As shown, it includes: a support frame 1; a conveyor assembly 2, including: a conveyor belt 21, mounted on the support frame 1; a drive device 22, mounted on the support frame 1, which can drive the conveyor belt 21 through power transmission; and a sealing wax assembly 3, including: a housing 31, mounted on the support frame 1, with a feeding port 311 and a discharging port 312 at both ends of the housing 31; a heating element 32, located inside the housing 31; a pump body 33, connected to the discharging port 312 via a discharging pipe 313; and an atomizing nozzle 34, connected to the output end of the pump body 33 via a pipe.

[0031] The drive unit can be an electric motor, which drives the conveyor belt.

[0032] The top of the box has a feeding port for adding paraffin raw materials; the bottom has a discharge port for discharging liquid paraffin.

[0033] The heating element can be an electric heating wire, which can be installed inside the chamber to heat the chamber so that the paraffin inside the chamber is in a liquid state.

[0034] The pump body is used to pressurize and pump the paraffin solution in the tank to the atomizing nozzle so that the atomizing nozzle can spray out the paraffin solution; the pipe connecting the pump output end to the atomizing nozzle can be a telescopic pipe, which makes it easy to adjust the height position of the atomizing nozzle according to actual needs to meet usage requirements.

[0035] Instructions for use: Activate the drive unit and place the pathological paraffin block (cut side up) on the conveyor belt. The movement of the conveyor belt will cause the paraffin block to enter the sealing component area. When the paraffin block enters the spraying range of the atomizing nozzle, the pump will start, and the atomizing nozzle will spray out paraffin liquid, thereby sealing the cut surface of the paraffin block. The spraying time can be set to a timer. After spraying is completed, the pump will enter standby mode. The sealed paraffin block will continue to move forward and be removed from the conveyor belt by the laboratory personnel for subsequent processing. Repeat the above operation to seal other unsealed paraffin blocks.

[0036] Example 2

[0037] like Figures 1-4 As shown, the wax sealing device also includes: a carrying plate 4 for loading wax blocks; the carrying plate 4 is provided with several loading slots 41 at intervals in the length and / or width direction; in use, the wax blocks are placed into the loading slots 41 in sequence, and then the carrying plate 4 is placed on the conveyor belt 21. After the wax blocks are sprayed with paraffin wax by the atomizing nozzle 34, the carrying plate 4 is removed from the conveyor belt 21.

[0038] likeFigures 1-4 As shown, the carrier plate 4 is made of magnetic metal; the corresponding conveying belt 21 is provided with a flexible magnetic strip 23, so that the carrier plate 4 and the flexible magnetic strip 23 are fixed by magnetic attraction.

[0039] As shown, the atomizing nozzle 34 is strip-shaped and can cover the carrier grooves 41 in the width direction of the carrier plate 4. Figure 1

[0040] As shown, the top of the discharge pipe 313 is Y-shaped, one end of the top is connected with the discharge port 312, and the other end is connected with a pressurizing device. Figure 1 Figure 5 As shown, the top of the discharge pipe 313 is Y-shaped, one end of the top is connected with the discharge port 312, and the other end is connected with a pressurizing device.

[0041] As shown, the top of the discharge pipe 313 is Y-shaped, one end of the top is connected with the discharge port 312, and the other end is connected with a pressurizing device. Figure 1 As shown, the wax sealing instrument further comprises a collection box 5 arranged at the end of the support 1 and used for storing the wax blocks after the wax sealing treatment.

[0042] The carrier grooves arranged on the carrier plate are used for placing pathological wax blocks, so as to avoid placing the wax blocks directly on the conveying belt and to avoid the problems of inconvenience in cleaning after being contaminated and inconvenience in placing the wax blocks.

[0043] The carrier plate is made of magnetic metal, such as iron-containing stainless steel material; the flexible magnet can use a rubber magnetic strip, which is an existing product; the carrier plate is fixed on the conveying belt by the magnetic attraction of the magnetic metal and the flexible magnet, so as to accurately spray the paraffin by the atomizing nozzle; handles can be arranged at both ends of the top to facilitate grasping and improve the convenience of use.

[0044] Since the carrier plate has a certain width and length, in order to facilitate the atomizing nozzle to spray paraffin liquid, a long strip-shaped atomizing nozzle is adopted, so that the paraffin sprayed from the nozzle also has a certain width, which can ensure that the carrier grooves in the width range of the carrier plate can be covered, so as to seal the wax blocks in the carrier grooves with paraffin.

[0045] Since the paraffin liquid will solidify after the temperature drops, in order to prevent the residual paraffin liquid from solidifying and blocking in the pipeline when the atomizing nozzle sprays, the discharge pipe is arranged in a Y shape, and valves are arranged at both ends of the top of the Y-shaped discharge pipe.

[0046] The top of the discharge pipe is connected with the discharge port and the pressurizing device respectively, that is, one end is used for discharging from the box, and the other end is used for conveying pressurized gas into the pipeline to blow out the residual paraffin liquid in the pipeline; in specific use, after the paraffin spraying is completed, the discharge port valve is closed, the pressurizing device is started to blow gas into the discharge pipe, and the paraffin in the pipeline is blown out by the pressure of the gas, so as to avoid pipeline blockage; after completion, the valve of the discharge pipe at this end is closed; the pressurizing device can be a gas pump or other existing products.

[0047] The collection box is arranged to store the wax blocks sealed on the conveying belt, so as to facilitate the experimental personnel to take and place, and prevent the pathological wax blocks on the conveying belt from accumulating.​​

[0048] Because pathological tissues vary in size, the embedding cassette molds used to prepare paraffin blocks come in various sizes, such as 2.0*2.0cm*0.7cm, 1.5*1.5cm*0.7cm, and 0.9*0.9cm*0.7cm. The different sizes of the grooves result in paraffin blocks of various shapes, which in turn leads to different sizes of cut surfaces formed on the paraffin blocks during sectioning. The sealing process only requires sealing the cut surfaces with wax. To facilitate the sealing of paraffin blocks of different shapes, multiple sets of loading slots of different sizes and shapes can be set on the substrate to accommodate paraffin blocks of different shapes.

[0049] The tray extends through the tray plate and has a structure that tapers from bottom to top, so as to fit the pathological paraffin block. One end of the cut surface of the paraffin block (containing the pathological tissue) is at the top of the tray (it can be flush with or slightly higher), which facilitates the sealing of the cut surface with paraffin.

[0050] The size of the top opening of the container can be pre-designed and manufactured according to the groove specifications of the main embedding box mold to meet the needs of wax blocks of different sizes.

[0051] At this time, the carrier plate includes a clamping plate 42 on the base plate and a handle on the top. The clamping plate 42 is used to clamp and fix the wax block from the bottom. The clamping plate and the base plate are movably connected. It is fixed when in use and can be loosened after use. The connection method can be screw connection, etc. The handle makes it easy to pick up the carrier plate. It can also be used to support the carrier plate when it is placed upside down to prevent the cut surface of the wax block from hitting the work surface and prevent contamination.

[0052] like Figures 2-4 As shown, during use, the carrier plate is placed upside down, causing the carrier slot to be inverted. At this time, the handle is supported on the work surface so that there is some distance between the carrier slot and the work surface. Then, insert the wax block with one end facing down into the carrier slot. After the wax block is placed, use the clamp to fix the wax block firmly (the clamp and the carrier plate can be fixed with screws). Then, straighten the carrier plate so that the cut side of the wax block is facing up. Then, place the carrier plate on the conveyor belt to perform the wax sealing operation. After the operation is completed, remove the carrier plate and place it upside down. Loosen the clamp to remove the wax block from the carrier slot and straighten it.

[0053] Since the tissue-containing end of the pathological paraffin block has various sizes, to avoid the paraffin liquid sprayed during the sealing operation adhering to the carrier plate and causing waste, several atomizing nozzles can be set in the width direction of the carrier plate to ensure that the cut surface of the paraffin block can be sealed with paraffin. The paraffin adhering to the carrier plate can be cleaned and recycled periodically.

[0054] Example 3

[0055] like Figure 1As shown, the wax sealing instrument further comprises: a blowing device 6 arranged on the side of the support 1 and used for blowing air towards the conveying belt 21; the blowing device 6 is arranged on the support 1 between the wax sealing assembly 3 and the collection box 5.

[0056] As shown, the conveying assembly 2 further comprises: a scraper 24 arranged on the support 1 below the end of the conveying belt 21; the scraper 24 is connected with the conveying belt 21; and a waste box 25 is arranged below the scraper 24. Figure 1 Since the wax used for sealing is in a molten state, in order to accelerate the solidification of the wax sprayed on the pathological wax block, a blowing device is used to blow cold air; the blowing device is arranged on the support, so that after the atomizing nozzle sprays the wax, the blowing device blows cold air to solidify the wax, and then the object plate can be taken out and the solidified wax block can be transferred to the collection box.

[0057] Since part of the wax sprayed by the atomizing nozzle will be sprayed on the conveying belt, in order to avoid affecting the normal use of the conveying belt, a scraper is arranged; since the interval between the scraper and the conveying belt is very small, when the accumulated wax reaches a certain thickness, it will be scraped off by the scraper; the scraped wax falls into the waste box; the length of the scraper can be slightly greater than or equal to the width of the conveying belt, so as to ensure that the wax adhering to the conveying belt can be fully scraped off.

[0058] The blowing device is arranged above the conveying belt and can be a small fan; the blown air passes through the conveying belt, which can accelerate the solidification of the wax used for sealing.

[0059] In use, the blowing device is kept in an activated state and continuously blows cold air towards the conveying belt; since the wax block is small in mass, if the wind speed is too high, the wax block can be blown down, which affects the sealing effect; therefore, the cold air blown by the blowing device should pass above the wax block, the wax block on the object plate should not be blown, and the wind speed should not be too high.

[0060] In order to avoid confusion of the samples during the sealing process, numbers can be arranged on the side of the object groove, which facilitates the placement and identification of the wax block.

[0061] The driving device, heating element, pump body, pressurizing device and blowing device involved in the present application are not the innovation points of the present application, and specific models will not be described herein; the electrical components adopt the existing connection mode, and the power supply can be a commercial power supply.
