Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an in-tube heating device for a dewaxing liquid of a separate drop-staining system for pathological tissues. Background Art

[0002] At present, the existing methods for dewaxing pathological tissue sections on the market include environmental protection type and xylene dewaxing. During the environmental protection type dewaxing process, there may be a problem that paraffin cannot be completely removed, which may affect the work efficiency of the laboratory and the reading and diagnosis of tissue sections. Xylene dewaxing has high volatility and is easy to be released into the air during operation, which may cause pollution to air quality and the ecological system. Prolonged or frequent contact with xylene may cause dizziness and pose a risk to the health of operators.

[0003] The existing dewaxing devices have the problem of incomplete dewaxing, and most of them are heated by solenoid valves, resulting in poor system stability and reliability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an in-tube heating device for a dewaxing liquid of a separate drop-staining system for pathological tissues, aiming to facilitate cleaner dewaxing during dewaxing and improve the stability and reliability of the system.

[0005] To achieve the above purpose, the utility model provides an in-tube heating device for a dewaxing liquid of a separate drop-staining system for pathological tissues, which includes a device body and a heating body. The heating body includes a heating and heat preservation sleeve and a heating body sleeve. The heating and heat preservation sleeve is sleeved into the heating body, and the heating body sleeve is sleeved into the heating and heat preservation sleeve. An auxiliary component is also included;

[0006] The auxiliary component includes a winding tube, a temperature control switch, a temperature sensor, a heating rod, a fixing plate, a heat preservation component, and a fixing component. The winding tube is connected to the heating body and is located inside the heating body sleeve. The temperature control switch is inserted on the upper side of the heating body, the temperature sensor is installed on the upper side of the heating body, the heating rod is inserted into the heating body, the fixing plate is connected to the fixing component, the heat preservation component is arranged on the upper and lower sides of the heating body, and the fixing component is arranged on one side of the fixing plate.

[0007] Wherein, the heat preservation component includes an upper heat preservation cotton and a lower heat preservation cotton. The upper heat preservation cotton is fixedly connected to the heating body and is located on the upper side of the heating body; the lower heat preservation cotton is fixedly connected to the heating body and is located on the lower side of the heating body.

[0008] Wherein, the fixing member includes an upper fixing piece and a lower fixing piece. The upper fixing piece is installed on the upper side of the heating body and connected to the fixing plate; the lower fixing piece is installed on the lower side of the heating body and connected to the fixing plate.

[0009] Wherein, the upper side direction of the winding tube is the direction for the dewaxing liquid to enter.

[0010] Wherein, the winding tube is a spiral tube and is installed in the heating body.

[0011] In the dewaxing liquid tube internal heating device of a staining system for separate dropwise staining of pathological tissues of the present utility model, the winding tube is installed in the heating body, the temperature control switch and the temperature sensor are installed in the heating body, the heat preservation member is used for heat preservation. After the dewaxing liquid enters the winding tube, it is heated by the heating rod and conducts heat to the connection between the heating body and the winding tube. The temperature of the dewaxing liquid will rise conductively. When the temperature is heated to the set range, the temperature control switch gets the feedback for heat preservation, so as to accurately control the temperature of the dewaxing liquid and ensure dewaxing within an appropriate temperature range. An appropriate temperature can promote the dissolution of wax and the complete removal of wax in the tissue, thereby reducing the possibility of incomplete dewaxing. Further, this heating device heats the dewaxing liquid reagent without passing through the solenoid valve, which can improve the stability and reliability of the system. As a mechanical device, the solenoid valve may have risks of wear and failure during long-term heating. Using a heating device that directly does not pass through the solenoid valve can simplify the system and reduce potential operation failures, and further facilitate clean dewaxing during dewaxing and improve the stability and reliability of the system.

Through the foregoing solution, it is more conducive to clean dewaxing during dewaxing, and the stability and reliability of the system can be improved. It can be understood that the foregoing solution can be more conducive to clean dewaxing and improve the stability and reliability of the system.

[0018] In this embodiment, the heating body 102 includes a heating and heat preservation sleeve 108 and a heating body sleeve 109.

The device body 1 is assembled by the heating body 102 and each component, and the heating and heat preservation sleeve 108 can be used for heat preservation.

[0019] Among them, the winding tube 101 is connected to the heating element 102 and is located inside the heating element sleeve 109. The temperature control switch 103 is inserted on the upper side of the heating element 102, and the temperature sensor 104 is installed on the upper side of the heating element 102. The heating rod 105 is inserted into the heating element 102. The fixing plate 112 is connected to the fixing member. The heat preservation member is arranged on the upper and lower sides of the heating element 102, and the fixing member is arranged on one side of the fixing plate 112. During assembly, after the winding tube 101 is connected and installed with the heating element 102, it will extend to the outside to facilitate the entry of the dewaxing liquid. The temperature control switch 103 can be directly inserted into the upper side of the heating element 102 for temperature control. The temperature sensor 104 is arranged and installed on the upper side of the heating element 102 for temperature detection. The heating rod 105 can be directly inserted into the heating element 102 for heating. The fixing plate 112 is used for installation and cooperation. The heat preservation member is used for heat preservation. The fixing member is used for fixing and cooperation.

[0020] Secondly, the upper heat preservation cotton 106 is fixedly connected to the heating element 102 and is located on the upper side of the heating element 102; the lower heat preservation cotton 107 is fixedly connected to the heating element 102 and is located on the lower side of the heating element 102.
