Description

Technical Field

[0001] The utility model relates to the technical field of pathological wax block sections, in particular to a novel constant cooling and humidity instrument for pathological wax blocks. Background Art

[0002] Pathological sections are made by cutting biopsy tissues and surgically removed specimens into suitable tissue blocks by pathologists in the pathology department. The tissue blocks are then dehydrated, made transparent, embedded, dipped in wax, and finally sliced. The cut tissues are placed on glass slides and go through a series of procedures such as staining and sealing. The resulting tissue sections are pathological sections.

[0003] Tissue wax blocks must go through a freezing and cooling process before slicing. During this process, if the temperature of the wax block is too high or too low, it will affect the quality and speed of slicing. Similarly, the humidity on the surface of the wax block in different seasons also affects the quality and speed of slicing. The currently used freezing tables do not have a humidification function, and the wax blocks are frozen in the air for too long, resulting in difficult and incomplete slicing, which in turn has a negative impact on film reading and diagnosis.

[0004] In the prior art, an open freezing table is mainly used, and a humidifier is placed on or near the slicer to indirectly increase the humidity of the wax block surface by increasing the humidity of the environment near the slice. However, the following problems exist during use: ① The freezing temperature is uneven. After the embedding is completed, only the bottom of the wax block is directly contacted and frozen. The paraffin is prone to cracking during the rapid cooling process, resulting in an unsightly wax block. In addition, there is a temperature difference between the surface of the wax block and the ground. The slicing process requires repairing the wax block layer by layer. When cutting to the middle of the wax block, the temperature is not low enough, and the slices stick together and curl during slicing. ② The open freezing table has a long refrigeration time and high energy consumption. ③ Lack of humidity control: The wax block is exposed to the air for a long time, resulting in dry tissue, and it is impossible to cut out complete tissue during slicing. For this reason, we propose a new type of pathology wax block constant cooling and humidity instrument. Utility Model Content

[0005] Therefore, the purpose of the utility model is to provide a novel constant cooling and humidity instrument for pathological wax blocks. Through the cooperation of the constant cooling and humidity frame component and the constant cooling and humidity component, a semi-closed structural design is formed when in use, which reduces energy consumption, and evenly humidifies the pathological wax blocks according to real-time changes in temperature and humidity. The temperature of the wax blocks is maintained while the humidity of the wax blocks is maintained, thereby avoiding the problem of poor slicing effect caused by uneven temperature and humidity, saving time, and improving slicing effect.

[0006] In order to solve the above technical problems, according to one aspect of the utility model, the utility model provides the following technical solutions: a new type of pathological wax block constant cooling and humidity instrument, comprising:

[0007] A constant cooling and humidity frame assembly, the constant cooling and humidity frame assembly comprising a constant temperature box, a ventilation installation hole opened on the surface of the constant temperature box, a drive motor located in the ventilation installation hole, a spiral fan blade connected to the output end of the drive motor, and an L-shaped support frame connecting the drive motor to the constant temperature box;

[0008] A constant cooling and humidity component, which includes a first electric shaft arranged on the inner side of the constant temperature box, a concave placement frame connected to the first electric shaft, a through hole opened on the inner bottom surface of the concave placement frame, a second electric shaft arranged on two opposite sides inside the concave placement frame, a mesh pressure plate connected to the second electric shaft, a columnar humidifier arranged on the inner bottom surface of the constant temperature box, and a temperature and humidity detector arranged on the inner wall of the constant temperature box.

[0009] As a preferred solution of the novel pathological wax block constant temperature and humidity instrument described in the utility model, wherein the ventilation installation holes are provided with four, and the four ventilation installation holes are distributed on two sides of the constant temperature box;

[0010] Wherein, a corresponding driving motor and spiral fan blades are arranged inside each ventilation mounting hole.

[0011] As a preferred solution of the novel pathological wax block constant cooling and humidity instrument described in the utility model, a plurality of columnar humidifiers are provided, and the plurality of columnar humidifiers are distributed at equal intervals.

[0012] As a preferred solution of the novel pathological wax block constant temperature and humidity instrument described in the utility model, a pathological wax block is placed on the inner surface of the concave placement frame, and the second electric rotating shaft drives the mesh pressing plate to press on the surface of the concave placement frame.

[0013] As a preferred solution of the new type of pathological wax block constant temperature and humidity instrument described in the utility model, it also includes an expansion component, which includes a slide groove opening opened on the inner side of the constant temperature box, a slider inserted into the slide groove opening and connected to the first electric rotating shaft, and a slide groove frame arranged at the outer frame position of the constant temperature box.

[0014] As a preferred solution of the novel pathological wax block constant temperature and humidity instrument described in the utility model, the slide slot frame and the slide slot opening are located in the same horizontal plane, and the slide slot frame and the slide slot opening are connected to each other.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1. The utility model achieves a semi-closed structural design when in use through the cooperation of the constant cooling and humidity frame component and the constant cooling and humidity component, thereby reducing energy consumption and evenly humidifying the pathological wax block according to real-time temperature and humidity changes, maintaining the temperature of the wax block while maintaining the humidity of the wax block, avoiding the problem of poor slicing effect caused by uneven temperature and humidity, saving time and improving slicing effect.

[0017] Second, based on the beneficial effect one, by setting the expansion component, it is convenient for the user to completely place the entire concave placement frame outside and support it, so that it is convenient for the operator to take out the pathological wax block, solving the problem that the operator cannot take the required pathological wax block in time in a small-scale constant temperature box;

[0018] During specific use, the user places the pathological wax block on the surface of the concave placement frame, and the second electric shaft drives the mesh pressure plate to flip downward, so that the mesh pressure plate can press the distributed pathological wax block. At this time, the first electric shaft drives the entire concave placement frame to rotate, so that the distributed columnar humidifiers humidify the constant temperature box. At this time, the rotating concave placement frame improves the uniformity of humidification of the pathological wax block, thereby ensuring the slicing effect and slicing speed of the pathological wax block. The temperature and humidity detector monitors the temperature and humidity in the entire constant temperature box environment in real time, which facilitates more accurate control of the temperature and humidity in the constant temperature box. When the temperature and humidity detector detects that the humidity in the constant temperature box is high, the drive motor drives the spiral fan blades to rotate for efficient ventilation to prevent freezing inside the instrument due to excessive air humidity.

[0028] The utility model provides a novel constant cooling and humidity instrument for pathological wax blocks. Through the cooperation of the constant cooling and humidity frame component and the constant cooling and humidity component, a semi-closed structural design is formed when in use, which reduces energy consumption, and evenly humidifies the pathological wax blocks according to real-time temperature and humidity changes, maintains the humidity of the wax blocks while maintaining the temperature of the wax blocks, avoids the problem of poor slicing effect caused by uneven temperature and humidity, saves time, and improves the slicing effect.

[0029] Example 1

[0030] Figure 1 , Figure 2 The utility model shows a schematic diagram of the overall structure of a new type of pathological wax block constant cooling and humidity instrument. Figure 1 , Figure 2 The main structure of this embodiment includes: a constant cooling and humidity frame component and a constant cooling and humidity component.

[0031] The constant cooling and humidity frame assembly is used for installation support to form a semi-enclosed humidification environment. Specifically, the constant cooling and humidity frame assembly includes a constant temperature box 11, a ventilation installation hole 12 opened on the surface of the constant temperature box 11, a driving motor 13 located in the ventilation installation hole 12, a spiral fan blade 14 connected to the output end of the driving motor 13, and an L-shaped support frame 15 connecting the driving motor 13 and the constant temperature box 11;

[0032] During specific use, the thermostat 11 forms a semi-enclosed humidified environment, and when the humidity in the thermostat 11 is high, the drive motor 13 drives the spiral fan blades 14 to rotate for efficient ventilation to prevent freezing inside the instrument due to excessive air humidity.

[0033] The constant cooling and humidity component is used for uniform humidification. Specifically, the constant cooling and humidity component includes a first electric shaft 21 arranged inside the thermostat 11, a concave placement frame 22 connected to the first electric shaft 21, a through hole 23 opened on the inner bottom surface of the concave placement frame 22, a second electric shaft 24 arranged on two opposite sides inside the concave placement frame 22, a mesh pressing plate 25 connected to the second electric shaft 24, a columnar humidifier 26 arranged on the inner bottom surface of the thermostat 11, and a temperature and humidity detector 27 arranged on the inner wall of the thermostat 11;

[0034] During specific use, the user places the pathological wax block on the surface of the concave placement frame 22, and the second electric shaft 24 drives the mesh pressure plate 25 to flip downward, so that the mesh pressure plate 25 can press the distributed pathological wax block. At this time, the first electric shaft 21 drives the entire concave placement frame 22 to rotate, so that the distributed columnar humidifiers 26 humidify the constant temperature box 11. At this time, the rotating concave placement frame 22 improves the uniformity of humidification of the pathological wax block, thereby ensuring the slicing effect and slicing speed of the pathological wax block. The temperature and humidity detector 27 monitors the temperature and humidity in the entire constant temperature box 11 environment in real time, which is convenient for more accurate control of the temperature and humidity in the constant temperature box 11.

[0035] Example 2

[0036] Please refer to Figure 3 , the incubator 11 forms a semi-closed humidification environment, and the concave placement frame 22 is located in the incubator 11. Although such a structural design has a good humidification effect, when the user needs to take out the pathological wax block, the environment inside the incubator 11 is small, so when taking out the pathological wax block, the space is limited, and the incubator 11 has a certain depth, so that when the operator takes out the pathological wax block, there are obstacles and it is inconvenient to operate. Therefore, through the provided expansion component, it is convenient for the user to completely place the entire concave placement frame 22 outside and support it, so that it is convenient for the operator to take out the pathological wax block, and solve the problem that the operator cannot take the required pathological wax block in time in the small range of the incubator 11;

[0037] Specifically, it also includes an expansion component, which includes a slide slot opening 31 opened on the inner side of the thermostatic box 11, a slider 32 inserted into the slide slot opening 31 and connected to the first electric shaft 21, and a slide slot frame 33 arranged at the outer frame position of the thermostatic box 11;

[0038] The chute frame 33 and the chute opening 31 are located on the same horizontal plane, and the chute frame 33 and the chute opening 31 are connected to each other;

[0039] During specific use, since the slide groove frame 33 and the slide groove mouth 31 are interconnected, the user pulls the concave placement frame 22 horizontally, and the concave placement frame 22 drives the slider 32 to slide in the slide groove mouth 31 and the slide groove frame 33. In this way, when the slider 32 slides into the slide groove frame 33, the entire concave placement frame 22 can be completely externalized, making it convenient for the user to take the pathological wax block he needs.

[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
