Description

Technical Field

[0001] The utility model relates to the technical field of dewaxing liquid recovery, in particular to a device for recovering and processing dewaxing liquid for tissue sections. Background Art

[0002] To explore the disease processes occurring in organs, tissues or cells, diseased tissues or cells are made into sections or smears, and after staining, they are observed under a microscope. Paraffin section is the most widely used method in the conventional histological section preparation technology. Its production method is as follows: the tissue is processed through operations such as fixation, sampling, washing, dehydration, clearing, and wax infiltration, so that paraffin infiltrates into the tissue and is embedded to form a wax block, and then sectioning, spreading, and baking are carried out to obtain the paraffin section. The obtained paraffin section can be observed under a microscope only after going through steps such as dewaxing, staining, re - dehydration, re - clearing, and sealing.

[0003] When paraffin tissue sections are dewaxed, usually xylene, the dewaxing liquid, is used to separate the sections from the paraffin. The dewaxing solution is directly drained away. With more and more paraffin tissue sections being dewaxed, more dewaxing liquid is wasted. Therefore, a device for recovering and processing dewaxing liquid for tissue sections is proposed. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a device for recovering and processing dewaxing liquid for tissue sections, which solves the problem that the dewaxing solution is directly drained away, resulting in more waste of dewaxing liquid.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A device for recovering and processing dewaxing liquid for tissue sections includes a recovery box and a processing box fixedly connected to the top of the recovery box through a fixing rod. A sealing cover is arranged on the top of the processing box. A sliding rod is slidably connected to the top of the sealing cover through an opening. A floating plate is fixedly connected to the bottom end of the sliding rod. A liquid suction pipe is communicated with the bottom of the floating plate. One end of the liquid suction pipe penetrates through the sealing cover and extends above the sealing cover. A sealing hole adapted to the liquid suction pipe is opened on the top of the sealing cover. A fixing ring is fixedly connected to the upper part of the outer surface of the sliding rod. The outer surface of the fixing ring is fixedly connected to the outer surface of the liquid suction pipe through a fixing block. An extraction pump is fixedly connected to the outer surface of the processing box through a connecting block. The liquid inlet end of the extraction pump is communicated with a liquid inlet pipe. One end of the liquid inlet pipe is communicated with one end of the liquid suction pipe. The liquid outlet end of the extraction pump is communicated with a liquid outlet pipe. One end of the liquid outlet pipe penetrates through the recovery box and extends into the interior of the recovery box.

[0006] Preferably, a filter frame is arranged at the bottom of the floating plate and below the liquid suction pipe.

[0007] Preferably, mounting plates are fixedly connected to the upper parts of both sides of the filter frame.

[0008] Preferably, the bottom of the mounting plate and the bottom of the floating plate are threadedly connected with bolts through openings.

[0009] Preferably, a support column is fixedly connected to the bottom of the floating plate and on one side of the filter box.

[0010] Preferably, a support column is fixedly connected to the bottom of the floating plate.

[0011] Beneficial effects

[0012] The utility model provides a device for recovering and treating a dewaxing solution for tissue sections. Compared with the prior art, the following beneficial effects are achieved:

[0013] (1) By adding the dewaxing solution to the treatment tank for precipitation, the floating plate will float in the upper layer of the liquid, so that the liquid suction pipe follows the floating plate in the upper layer of the liquid. The upper layer of the liquid is extracted through the liquid inlet pipe and the liquid suction pipe on the extraction pump, and the upper layer of the dewaxing solution is pumped into the recovery tank through the liquid outlet pipe. Therefore, the dewaxing solution can be well recovered and treated, reducing the waste of the dewaxing solution.

[0014] (2) With the filter box below the liquid suction pipe, the liquid extracted by the liquid suction pipe is filtered to prevent sediment from entering the liquid suction pipe. Description of the drawings

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0020] Please refer to Figures 1-3, the present utility model provides a technical solution: an apparatus for recycling and treating tissue section dewaxing liquid, including a recycling box 1 and a treatment box 2 fixedly connected to the top of the recycling box 1 through a fixing rod. A feeding pipe is communicated above the outer surface of the treatment box 2, and a discharging pipe is communicated at the bottom of the outer surface of the recycling box 1. A sealing cover 3 is arranged at the top of the treatment box 2. A sliding rod 4 is slidably connected to the top of the sealing cover 3 through an opening. A floating plate 5 is fixedly connected to the bottom end of the sliding rod 4. A liquid suction pipe 6 is communicated at the bottom of the floating plate 5. One end of the liquid suction pipe 6 penetrates through the sealing cover 3 and extends above the sealing cover 3. A sealing hole adapted to the liquid suction pipe 6 is opened at the top of the sealing cover 3. A fixing ring 7 is fixedly connected above the outer surface of the sliding rod 4. The outer surface of the fixing ring 7 is fixedly connected to the outer surface of the liquid suction pipe 6 through a fixing block. A suction pump 8 is fixedly connected to the outer surface of the treatment box 2 through a connecting block. The suction pump 8 is electrically connected to an external power supply and is controlled by a control switch. The liquid inlet end of the suction pump 8 is communicated with a liquid inlet pipe 9. One end of the liquid inlet pipe 9 is communicated with one end of the liquid suction pipe 6. The liquid outlet end of the suction pump 8 is communicated with a liquid outlet pipe 10. One end of the liquid outlet pipe 10 penetrates through the recycling box 1 and extends into the interior of the recycling box 1.

[0021] It should be noted that the sealing cover 3 can be taken out upwards, and the sealing cover 3 will take out the sliding rod 4, the floating plate 5 and the liquid suction pipe 6, and then the sediment in the treatment box 2 can be cleaned out.

[0022] Furthermore, in order to facilitate the sediment to enter the liquid suction pipe 6, a filter frame 12 is arranged below the bottom of the floating plate 5 and below the liquid suction pipe 6. Installation plates 13 are fixedly connected above both sides of the filter frame 12. The bottom of the installation plate 13 and the bottom of the floating plate 5 are threadedly connected with bolts 14 through openings.

[0023] It should be noted that by rotating the bolt 14, the filter frame 12 can be conveniently disassembled for cleaning.

[0024] Furthermore, in order to prevent the liquid suction pipe 6 from sticking to the precipitated paraffin and being blocked, a support column 11 is fixedly connected to the bottom of the floating plate 5.

[0025] During use, the used dewaxing liquid is added into the treatment box 2 through the feeding pipe and precipitated in the treatment box 2. The paraffin will precipitate at the bottom of the treatment box 2, and the dewaxing liquid is in the upper layer. The floating plate 5 will float on the upper layer of liquid. Then, the liquid inlet pipe 9 on the suction pump 8 is controlled to pump liquid, so that the liquid inlet pipe 9 extracts the upper layer of liquid in the treatment box 2 through the liquid suction pipe 6. At the same time, the filter frame 12 will filter the upper layer of liquid extracted by the liquid suction pipe 6, and the upper layer of liquid is pumped into the recycling box 1 through the liquid outlet pipe 10 for recycling. As the upper layer of liquid decreases, the floating plate 5 will descend along with the upper layer of liquid, and the support column 11 will descend onto the precipitated paraffin.
