Technical Field
[0001] This application relates to the technical field of dye solution replacement, specifically to a device for replacing the dye solution path and collecting waste liquid in the dyeing process. Background Art
[0002] In the field of HE instrument slide staining in pathological clinics, traditional slide staining work mainly relies on manual operation. Medical staff usually manually replace the old and new dye solutions in the dyeing vats. However, this manual operation method has many drawbacks. During the process of pouring the dye solution into the dyeing vat and pouring the waste liquid from the dyeing vat into the medical waste collection bucket, due to complete reliance on manual operation and lack of precise control means, the dye solution is very likely to spill. The spillage of the dye solution not only causes chemical harm to the bodies of medical staff, but also pollutes the laboratory environment, bringing potential safety hazards and cleaning problems to pathological clinical work. Currently, there is an urgent need for a dyeing vat dye solution replacement technology that can effectively avoid the spillage of the dye solution to improve the safety and environmental protection of pathological clinical work. Summary of the Utility Model
[0003] The purpose of this application is to provide a device for replacing the dye solution path and collecting waste liquid in view of the above problems existing in the prior art.
[0004] To achieve the above application purpose, this application adopts the following technical solutions: The device for replacing the dye solution path and collecting waste liquid includes:
[0005] A dyeing vat;
[0006] A reagent loading box with a cavity for accommodating reagents;

[0008] Among them, water flow is input through a water pump to control the piston to move back and forth at the water inlet, thereby affecting the pressure inside the cavity of the dyeing vat operation module; there are also an upper valve and a lower valve inside the dyeing vat operation module. The upper valve corresponds to the liquid discharge port and is used to open and close the liquid discharge port. The lower valve corresponds to the infusion port and is used to open and close the infusion port. The upper valve and the lower valve can be opened or closed under the influence of pressure;
[0009] When the pressure inside the cavity of the dyeing vat operation module is negative, the upper valve closes and the lower valve opens; when the pressure inside the cavity of the dyeing vat operation module is positive, the upper valve opens and the lower valve closes; when the pressure inside the cavity of the dyeing vat operation module is normal, both the upper valve and the lower valve close.
[0010] Further, when the piston moves towards the inside of the water inlet, the liquid discharge port opens and the liquid infusion port closes. At this time, the waste liquid in the dye vat flows back into the dye vat operation module and is discharged from the liquid discharge port. When the piston moves inside the dye vat operation module and the liquid discharge port opens, the liquid infusion port closes and the water inlet opens. At this time, water flows through the dye vat operation module and enters the water inlet and the liquid discharge port respectively. When the piston moves towards the outside of the water inlet to reach the maximum limit position, the water inlet closes, the liquid infusion port opens, and the liquid discharge port closes. The dye solution enters the dye vat from the reagent loading box through the dye vat operation module. When the piston moves to the initial position inside the water inlet, the liquid discharge port, the liquid infusion port, and the water inlet are all closed.
[0011] Further, a liquid level sensor is provided in the dye vat.

[0018] Compared with the prior art, the utility model has the following beneficial effects:
[0019] 1. Avoiding dye solution spillage and reducing pollution: In the traditional HE instrument for pathological clinical slide staining work, manual replacement of the dye solution by humans easily causes dye solution spillage, resulting in chemical pollution to the human body and the laboratory.

Compared with manual operation, it greatly improves work efficiency and reduces operation time and labor costs.
[0021] 3.

These are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.
[0032] Example 1
[0033] As Figure 1 shown, first, this dye solution path replacement and waste liquid collection device mainly consists of a dye vat 3, a reagent loading box 4, and a dye vat operation module 1. The dye vat 3 is used for dyeing slides. The reagent loading box 4 is provided with a cavity for accommodating reagents to supply dye solution to the dye vat 3. The dye vat operation module 1 is provided with a water inlet, a drain port 2, an outlet port 11, and an infusion port.
[0034] A piston 6 is provided at the water inlet of the dye vat operation module 1. By inputting water flow through a water pump, the piston 6 is controlled to move back and forth at the water inlet. When the piston 6 moves, it will affect the pressure in the internal cavity of the dye vat operation module 1, thereby controlling the opening or closing of the upper valve 7 and the lower valve 8. The upper valve 7 corresponds to the drain port 2 and is used to open and close the drain port 2; the lower valve 8 corresponds to the infusion port and is used to open and close the infusion port. When the pressure in the internal cavity of the dye vat operation module 1 is in negative pressure, the upper valve 7 closes and the lower valve 8 opens; when the pressure is in positive pressure, the upper valve 7 opens and the lower valve 8 closes; when the pressure is normal, both the upper valve 7 and the lower valve 8 close.
[0035] The specific working process is as follows: When the piston 6 moves inward into the water inlet, the drain port 2 opens and the infusion port closes. At this time, the waste liquid in the dye vat 3 flows back into the dye vat operation module 1 and is discharged from the drain port 2. When the piston 6 moves inside the dye vat operation module 1 and the drain port 2 opens, the infusion port closes and the water inlet opens. At this time, the water flows through the dye vat operation module 1 and enters the water inlet and the drain port 2 respectively. When the piston 6 moves outward to the maximum limit position at the water inlet, the water inlet closes, the infusion port opens, and the drain port 2 closes. The dye solution enters the dye vat 3 from the reagent loading box 4 through the dye vat operation module 1. When the piston 6 moves to the initial position inside the water inlet, the drain port 2, the infusion port, and the water inlet all close.
[0036] A liquid level sensor is provided in the dye vat 3 to monitor the liquid level in the dye vat 3 in real time. When the liquid level is too low, the dye solution replenishment program can be automatically started through the control system. The dye vat operation module 1 is an electromagnetic reciprocating pump, which precisely controls the piston 6 to move back and forth inside the water inlet through the electromagnetic reciprocating pump to ensure the accuracy and stability of dye solution replacement and waste liquid collection.
[0037] A solenoid valve 9 is also provided at the water inlet, which is in the initial position. The solenoid valve 9 can further control the opening and closing of the water inlet, improving the safety and reliability of the device. The dyeing vat 3 is provided with a weighing module, which can weigh the dyeing vat 3 to accurately grasp the weight of the dye liquor in the dyeing vat 3 and provide more accurate data support for the dyeing work.
[0038] Silicone rings are provided between the dyeing vat 3 and the liquid outlet 11, and between the liquid infusion port and the reagent loading box 4, enhancing the sealing performance of the device and preventing the leakage of the dye liquor. The capacity of the reagent loading box 4 is larger than that of the dyeing vat 3, and the capacity is greater than or equal to 3L, which can meet the demand for dye liquor supply for a relatively long time.
[0039] In summary, through the automated design, this dye liquor path replacement and waste liquid collection device effectively avoids the problem of dye liquor spillage, improves the safety and environmental protection of pathological clinical work, and also improves the work efficiency and the quality of dyeing slides.
[0040] Embodiment 2
[0041] This embodiment demonstrates the specific working process of this dye liquor path replacement and waste liquid collection device.
[0042] As Figure 2 shown, when the system is not running, the trapezoidal piston 6 and the solenoid valve 9 are in the locked state. At this time, the piston 6 is in the initial position, the default liquid outlet 11 is closed, and the inside of the dyeing vat operation module 1 (electromagnetic reciprocating pump) is in a closed state.
[0043] As Figure 3 shown, when the system is running and it is necessary to add dye liquor into the dyeing vat 3, control the trapezoidal piston 6 to move horizontally to the right. The pressure in the pump chamber of the entire dyeing vat operation module 1 drops, causing the upper valve 7 to be pressed down, the corresponding port of the upper valve 7 to close, and the lower valve 8 to be lifted. The dye liquor in the reagent loading box 4 fills the pump chamber due to the pressure. When the liquid pressure in the chamber fills the pump chamber, the liquid outlet 11 opens, and the dye liquor is injected into the dyeing vat 3 through the liquid path pipeline. When the liquid level sensor detects that the height of the liquid surface in the dyeing vat 3 from the bottom of the vat is the height of the position where the sensor is installed, the injection of the dye liquor stops.
[0044] As Figure 4 shown, when it is necessary to discharge the waste liquid in the dyeing vat 3, control the trapezoidal piston 6 to move horizontally to the left. The pressure in the entire pump chamber rises until the piston 6 moves from right to left beyond the solenoid valve 9, causing the lower valve 8 to be pressed down, the corresponding port of the lower valve 8 to close, and the upper valve 7 to be lifted. The waste liquid in the dyeing vat 3 is discharged into the waste liquid collection box through the liquid outlet 11 and the pump chamber (the interface corresponding to the liquid discharge port 2 is connected to the waste liquid collection box).
[0045] As Figure 5As shown in the figure, when it is necessary to clean the water flow in the dyeing vat 3, control the trapezoidal piston 6 to continue moving horizontally to the left. At this time, all the waste liquid has been completely discharged. At this time, the lower valve 8 continues to be pressed down, and the corresponding port of the lower valve 8 is closed. The upper valve 7 continues to be lifted. When the trapezoidal piston 6 is pushed into the pump cavity, the lower valve 8 is locked. The clean water in the water inlet control module 5 (external structure, prior art) quickly fills the entire pump cavity and enters the dyeing vat 3 through the liquid outlet 11. When the weight of the clean water in the dyeing vat 3 detected by the weighing sensor reaches 0.8 kg, that is, the capacity reaches 800 ml, stop injecting clean water, and the piston 6 starts to move back until the piston 6 returns to the water inlet closed position (i.e., Figure 4 position), and the waste water is pumped out to the drain port 2 and enters the waste liquid collection bucket.
[0046] In this way, when the amount of dye liquor in the dyeing vat 3 is insufficient, the pipeline can automatically supplement the dye liquor to the standard liquid level height. When the dyeing effect of the dye liquor in the dyeing vat 3 decreases, the system can automatically discharge the waste liquid, clean the dyeing vat 3, and inject new dye liquor, which not only reduces the workload of medical staff, but also effectively protects the lives of medical staff. At the same time, the automated liquid change method can avoid the waste of dye liquor and enable quantitative control of dye liquor data, so as to stably control the dyeing image effect of the final dyed slices, which has great practical significance.
[0047] The parts not detailed in this application are prior art, so this application does not elaborate on them.
[0048] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of this element can be multiple. The term "one" cannot be understood as a limitation on the number.
[0049] Although this text uses terms such as the dyeing vat operation module 1, drain port 2, dyeing vat 3, reagent loading box 4, water inlet control module 5, piston 6, upper valve 7, lower valve 8, solenoid valve 9, liquid outlet 11, etc. more frequently, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of this application; interpreting them as any additional limitation is contrary to the spirit of this application.
[0050] This application is not limited to the above best implementation manner. Anyone can obtain other various forms of products under the inspiration of this application. However, no matter what changes are made in its shape or structure, as long as there are technical solutions identical or similar to this application, they all fall within the protection scope of this application.
