Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pathological slide baking equipment, specifically an automatic pathological slide baking machine. Background Technology
[0002] Pathological sections are prepared by taking a certain size of diseased tissue, using pathological histological methods, usually embedding the diseased tissue in a paraffin block, cutting it into thin sections with a microtome, staining it with hematoxylin and eosin (HE), further examining the occurrence and development of the lesion under a microscope, and finally making a pathological diagnosis.
[0003] After slicing with a microtome, the slices are placed in water. The surface tension and temperature of the water naturally flatten the slightly wrinkled slices. Once the slices are fully flattened on a constant-temperature water surface, in order to dry the moisture and ensure the tissue adheres tightly to the glass slide, the inventors discovered the following problems with the existing technology during the development of this invention:
[0004] The current method involves tilting the slide at the middle of a glass slide to remove excess water before placing it in a constant temperature oven for drying. This process is repeated before drying the next slide, making it time-consuming, cumbersome, and inefficient. Therefore, an automated slide drying machine for pathological samples is designed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4 This utility model provides a technical solution: an automatic pathological slide baking machine, including an outer frame 1, a baking assembly 2 on the surface of the outer frame 1, a switch 3 installed on the front of the outer frame 1, a water guide trough 4 on one side of the baking assembly 2, and a water storage tank 5 installed at one end of the water guide trough 4.
[0023] The baking sheet assembly 2 includes a panel 201, a barrier strip 202 is bonded to the upper surface of the panel 201, an LCD screen 203 is provided on the surface of the panel 201, a glass slide 204 is embedded in the surface of the panel 201, a shaft 205 is welded to the back of the panel 201, a knob 206 is installed at one end of the shaft 205, and a gasket 207 is sleeved on the surface of the shaft 205.
[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the barrier strip 202, the glass slide 204 and the liquid crystal display screen 203 are set as a group, and there are several groups in total. It should be noted that by setting the barrier strip 202 on the surface of the panel 201, the glass slide 204 is prevented from shifting when the tilt of the panel 201 is adjusted. Each glass slide 204 has an independent baking area at the bottom, and the temperature of each baking area is independently adjustable.
[0025] In this embodiment, as Figure 1 As shown, the panel 201 is internally equipped with a temperature sensor, a resistance wire, and a solid-state relay, and the temperature sensor and the LCD display 203 are electrically connected. It should be noted that each baking area is equipped with an independent temperature control system. After the glass slide 204 is placed in, the temperature sensor detects the temperature change and transmits the signal to the solid-state relay. The solid-state relay controls the resistance wire to be energized for heating. The LCD display 203 on each independent baking area is electrically connected to the temperature sensor to display the baking temperature and automatic start time in real time.
[0026] In this embodiment, as Figure 3 and Figure 4As shown, the panel 201 forms a rotating structure through the shaft 205, and the shaft 205 is rotatably connected to the outer frame 1. It should be noted that the shaft 205 passes through the outer frame 1, and rotating the knob 206 can drive the shaft 205 to rotate. The shaft 205 is welded to the panel 201, and the shaft 205 drives the panel 201 to rotate. The tilt angle of the panel 201 is adjustable, preferably 80°. The panel 201 can automatically drain water after tilting. The panel 201 is made of waterproof ceramic material, which is more durable.
[0027] In this embodiment, as Figure 4 and Figure 1 As shown, the shim 207 is located between the outer frame 1 and the surface of the panel 201. It should be noted that by adding the shim 207 between the inner wall of the outer frame 1 and the panel 201, the shim 207 increases the rotational resistance of the shaft 205. The shaft 205 will only rotate when an external force is applied. After the panel 201 is adjusted to a suitable angle, the angle of the control panel 201 remains unchanged.
[0028] In this embodiment, as Figure 1 and Figure 3 As shown, there are three water guide channels 4, and the three water guide channels 4 are arranged in parallel structure, and the water guide channels 4 are inclined relative to the outer frame 1. It should be noted that a water guide channel 4 is set on one side of each row of panels 201. After the residual water flows into the water guide channel 4 by gravity, the water in the three rows of water guide channels 4 converges into the water storage tank 5 to collect the residual water.
[0029] In this embodiment, as Figure 2 As shown, the water storage tank 5 and the outer frame 1 are connected by a sliding connection. It should be noted that the sliding connection between the water storage tank 5 and the outer frame 1 is designed to be detachable, so that the water can be removed and emptied at any time when the water in the tank is full.
[0030] The method of use and advantages of this utility model: The automatic pathological slide baking machine operates as follows:
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first rotate knob 206 to adjust the tilt angle of panel 201. Rotating knob 206 clockwise causes panel 201 to rotate clockwise until the lower part of panel 201 aligns with the water channel 4. The other side of panel 201 is connected in series with switch 3. Turning on switch 3 powers panel 201. Place the glass slide 204 with the thin sheet directly onto panel 201. The separator strips 202 separate the individual glass slides 204. After placing the glass slide 204, the temperature sensor (model: B395)... 0) A change in surface temperature of panel 201 is detected and the value is displayed on the surface of LCD screen 203. Automatic startup is initiated. A 51 microcontroller is installed between the resistance wire and the solid-state relay (model: SSR-25DA). A countdown of one minute begins. When the countdown ends, a signal is transmitted to the solid-state relay. The solid-state relay controls the resistance wire to be energized and heated to a preset temperature, for example, 60-75℃, preferably 65℃. The temperature is then kept constant. After the glass slide 204 is removed, the signal is transmitted to the solid-state relay again, and the power is automatically cut off.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
