[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a staining apparatus for pathological techniques. (See also...) Figure 1-6 A staining device for pathological techniques includes a dewaxing staining machine 1. The dewaxing staining machine 1 includes a base 101, a card holder 102 fixedly connected to the top of the base 101, a staining vat 103 movably connected to the inner cavity of the card holder 102, a support rod 104 fixedly connected to the back side of the top of the base 101, an L-shaped movable rod 105 movably connected to the inner cavity of the support rod 104, a staining chamber 107 fixedly connected to the bottom of the L-shaped movable rod 105, a sample compartment 108 fixedly connected to the inner cavity of the staining chamber 107, a shell 111 fixedly connected to the top of the base 101, a front door 109 rotatably connected to the front side of the shell 111 via a hinge, a first handle 110 fixedly connected to the front side of the front door 109, an electric push rod 106 fixedly connected to the top of the shell 111, the output end of the electric push rod 106 passing through the support rod 104 and the shell 111 and fixedly connected to the top of the L-shaped movable rod 105, and a filter mechanism 2 installed on the back side of the shell 111.

[0026] The filtration mechanism 2 includes a filter chamber 201, which is fixedly connected to the back side of the outer shell 111. A first pipe 202 is fixedly connected to the top of the filter chamber 201 and extends into the inner cavity of the outer shell 111. A filter screen 206 is movably connected to the top of the inner cavity of the filter chamber 201. A filter box 207 is movably connected to the inner cavity of the filter chamber 201. The top and bottom of the filter box 207 are provided with through holes 208, and there are several through holes 208. A support plate 214 is fixedly connected to the bottom of the inner cavity of the filter chamber 201. The inner cavity of the support plate 214 is provided with suction holes 211 of varying sizes. Motors 213 are fixedly connected to both sides of the inner cavity of the support plate 214. A blade 212 is fixedly connected to the output end of the motor 213, and there are several blades 212. An air outlet 215 is provided at the bottom of the back side of the filter chamber 201.

[0027] Reference Figure 2 and Figure 3 The other end of the first pipe 202 is connected to the second pipe 203. Both sides of the bottom of the second pipe 203 are connected to the third pipe 204. The surface of the third pipe 204 is provided with air grooves 205. There are several air grooves 205. By setting the leak-stopping plate 5, the ventilation area is increased, which can cover the inside of the outer shell 111 well and prevent the benzoxylene volatilization inside the outer shell 111 from being unable to be quickly sucked into the purification device.

[0028] Reference Figure 5 The top and bottom of the filter cartridge 207 are fixedly connected with non-woven fabric 209. The non-woven fabric 209 is filled with activated carbon 210. The non-woven fabric 209 protects the activated carbon 210 and prevents it from leaking out of the through hole 208. The activated carbon 210 can also filter the volatile gases of benzoxide to prevent them from being inhaled by the operator and affecting their health.

[0029] Reference Figure 4 A snap-fit ​​nozzle 3 is fixedly connected to the right side of the inner cavity of the filter chamber 201. The snap-fit ​​nozzle 3 snaps onto the surface of the filter screen 206. Support columns 4 are fixedly connected to the front and back sides of the inner cavity of the filter chamber 201. There are several support columns 4. The top of the support column 4 is movably connected to the bottom of the filter screen 206. The snap-fit ​​nozzle 3 is used to fix the filter screen 206 and prevent it from shaking after being inserted into the inner cavity of the filter chamber 201. The support columns 4 are also used to support the position of the filter screen 206 and prevent it from falling out after being inserted into the filter chamber 201.

[0030] Reference Figure 6A leak-stopping plate 5 is fixedly connected to the left side of the filter screen 206, and the right side of the leak-stopping plate 5 is attached to the left side of the filter chamber 201. A second handle 6 is fixedly connected to the left side of the leak-stopping plate 5, and a third handle 7 is fixedly connected to the left side of the filter box 207. The leak-stopping plate 5 can block the small gap between the filter chamber 201 and the filter screen 206, preventing benzoxide volatile gas from escaping from the gap and affecting the health of the operator. The second handle 6 allows the operator to easily remove and replace the filter screen 206 from the filter chamber 201.

[0031] Reference Figure 3 , Figure 4 and Figure 5 Both sides of the inner cavity of the filter chamber 201 are fixedly connected to sliders 9, and both sides of the filter box 207 are provided with sliding grooves 8. The surface of the sliders 9 is movably connected to the inner cavity of the sliding grooves 8. Through the cooperation of the sliding grooves 8 and the sliders 9, the filter box 207 is supported and guided, making the movement of the filter box 207 more stable and preventing the filter box 207 from falling or shaking.

[0032] Reference Figure 1 A leather ring 10 is fixedly connected to the bottom of the dyeing chamber 107. The leather ring 10 is square and its diameter is larger than that of the dyeing vat 103. The bottom of the leather ring 10 fits against the top of the dyeing vat 103. A rubber pad 11 is fixedly connected to the back of the front door 109. The rubber pad 11 is made of rubber. The leather ring 10 prevents xylene solvent from splashing out of the inner cavity of the dyeing vat 103 when the test material is dewaxed. The rubber pad 11 also prevents xylene volatile gas from leaking out of the inner cavity of the outer shell 111 when the front door 109 is closed.

[0033] Working principle: First, the tissue to be stained is placed in the inner cavity of sample chamber 108 for dewaxing. The front door 109 is closed. Then, the electric push rod 106 is activated to drive the L-shaped movable rod 105 downwards until it is immersed in the phthalic acid solution inside the staining tank 103. At this time, the motor 213 is activated to drive the blade 212 to rotate. The rotation of the blade 212 provides power for extracting the phthalic acid volatile gas inside the outer shell 111. The phthalic acid volatile gas is then sucked into the third pipe 204 through the gas groove 205, and then into the first pipe 202. The phthalic acid volatile gas is then transported to the filter chamber 201 through the first pipe 202. After entering the filter chamber 201, the phthalic acid volatile gas first undergoes preliminary filtration through the filter screen 206 to remove particles from the gas. The filter intercepts the phthalic acid gas, which then enters the filter cartridge 207 through the through-hole 208. When the gas comes into contact with the non-woven fabric 209, it is further filtered. The phthalic acid gas then enters the activated carbon 210, which adsorbs the toxic and harmful substances in the phthalic acid gas. It is then filtered again through the non-woven fabric 209 at the bottom of the activated carbon 210, so that the phthalic acid gas is finally purified into standard gas and then discharged through the outlet 215. When the fine particles deposited on the surface of the filter screen 206 reach a certain level, the second handle 6 can be pulled to remove the filter screen 206 from the filter chamber 201 for cleaning. When the filter cartridge 207 needs to be replaced, the third handle 7 can also be pulled out for replacement, achieving a convenient and quick effect.

[0034] 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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
