Description

Technical Field

[0001] This utility model relates to the field of pathological analysis technology, and more specifically, to a reagent bottle, a tissue dehydration device, and a tissue processing device. Background Technology

[0002] In the fields of medical testing and pathological analysis, reagent bottles need to store specific organic solvents for extended periods. Key requirements include chemical compatibility, resistance to deformation and sealing, and cost control. High-density polyethylene (HDPE) has become the mainstream bottle material due to its inherent solvent resistance; however, the difference in solubility parameters between organic solvents and HDPE can easily cause bottle swelling, leading to seal failure, leakage risks, and threatening laboratory safety.

[0003] Existing anti-swelling technologies typically involve adding reinforcing ribs to the bottle body, but this only increases local rigidity and cannot suppress internal swelling stress; or thickening the wall, which, while providing short-term deformation resistance, leads to a surge in material costs, makes the molding process prone to shrinkage marks and warping, and still poses a risk of breakage due to stress concentration in the transition area of ​​the bottle body.

[0029] Please refer to Figure 1This embodiment provides a reagent bottle 100, including a bottle body 110, which has a cavity 111 for containing a solution; it also has at least one opening communicating with the cavity 111, through which the solution flows into the cavity 111; a connecting part 120 is provided inside the cavity 111, with both ends of the connecting part 120 respectively connected to two inner walls disposed opposite to each other in the cavity 111, and the connecting part 120 is located in the middle of the inner wall.

[0030] Specifically, the reagent bottle 100 includes a bottle body 110, and a cavity 111 inside the bottle body 110 is used to store the solution; the bottle body 110 is provided with at least one opening communicating with the cavity 111, and the solution can flow into the cavity 111 through the opening, thus meeting the needs for adding solution in different usage scenarios.

[0031] like Figure 2 As shown, a connecting portion 120 is provided inside the cavity 111. The two ends of the connecting portion 120 are respectively connected to two opposing inner walls of the cavity 111, thereby forming a support structure inside the bottle body 110. When the organic solvent causes swelling stress in the bottle body 110, the connecting portion 120 enables the opposing surfaces to mechanically support each other. Preferably, the opposing ends of the connecting portion 120 are respectively connected to two main pressure-bearing surfaces inside the bottle body 110, i.e., the two opposing surfaces with the largest area inside the bottle body 110.

[0032] In one embodiment of this application, the bottle body 110 and the connecting part 120 are made of a polymer material. The polymer material has good chemical resistance, effectively resisting corrosion from various chemical reagents, preventing chemical reactions between the bottle body 110 and the connecting part 120 and the solution, preventing material corrosion and damage, ensuring the purity and stability of the solution, and extending the service life of the reagent bottle 100. Furthermore, the bottle body 110 and the connecting part 120 are integrally molded, eliminating gaps between them and effectively preventing solution from seeping through. The risk of leakage is significantly reduced, improving the sealing performance of reagent bottle 100 and ensuring that the solution inside the bottle will not be wasted, pollute the environment, or cause safety accidents due to leakage. Furthermore, the one-piece molding makes the bottle body 110 and the connecting part 120 form a complete and continuous structure, enhancing the overall mechanical strength and stability. When subjected to external forces, it can better disperse stress and reduce local stress concentration. Compared with non-one-piece molding structures, it is less likely to have problems such as breakage or detachment of the connecting part 120, further ensuring the safety of reagent bottle 100 during storage and transportation.

[0033] It should be noted that, firstly, in order to further enhance the structural stability of the reagent bottle 100, in one possible embodiment of this application, the connecting portion 120 is located in the middle of the inner wall. This arrangement can more evenly distribute the stress on the cavity 111 onto the two opposing inner walls, further avoiding local stress concentration. Compared to the connecting portion 120 being located in other positions, it can better resist the risk of deformation and breakage.

[0034] Second, in one possible embodiment of this application, the number of connecting portions 120 within the cavity 111 is at least one; when the number of connecting portions 120 is one, preferably, the connecting portion 120 can be located in the middle of the two opposite surfaces with the largest area within the bottle body 110; when the number of connecting portions 120 is multiple, the multiple connecting portions 120 are connected to at least one pair of oppositely arranged inner walls, wherein multiple connecting portions 120 can be provided between a pair of oppositely arranged inner walls, or one or more connecting portions 120 can be provided between multiple pairs of oppositely arranged inner walls respectively; and when multiple connecting portions 120 are provided between a pair of oppositely arranged inner walls, these connecting portions 120 can be evenly distributed, or can be connected to any position of the two oppositely arranged inner walls, and this application does not impose any restrictions on this.

[0035] Third, in one possible implementation of this application, such as Figure 1 and Figure 2 As shown, the outer wall of the cavity 111 has a reinforcing portion 114 recessed towards the cavity 111 to effectively enhance the rigidity of the bottle body 110. This application does not impose any limitations on the specific structure of the reinforcing portion 114. For example, the reinforcing portion 114 can be multiple rectangular blocks uniformly recessed into the side wall of the bottle body 110, with reinforcing ribs formed between adjacent rectangular blocks to enhance the rigidity of the bottle body 110, further reducing the possibility of outward expansion of the bottle body, improving deformation resistance, sealing performance, and reliability.

[0036] Of course, in addition to the rectangular block structure, the reinforcing part 114 can also be other shaped structures, such as a recessed circular structure, a triangular structure, etc. This application does not impose any restrictions on this, as long as it can effectively enhance the rigidity of the bottle body 110.

[0037] The reagent bottle 100 described above, through the connection part 120, can form a support structure inside the bottle body 110. When the organic solvent causes swelling stress in the bottle body 110, the connection part 120 can hold the two sides of the bottle body 110, preventing the bottle body 110 from expanding to both sides and reducing the risk of the bottle body 110 expanding and breaking. Compared with the prior art of setting reinforcing ribs in the bottle body, the reagent bottle 100 of this application not only improves the local rigidity, but also avoids molding process problems such as shrinkage marks and warping in the bottle body 110. While ensuring the anti-swelling performance of the reagent bottle 100, it also takes into account the cost and process feasibility.

[0038] For example, the connecting part 120 has a columnar structure, and the two opposite ends of the connecting part 120 have grooves 121 extending toward the cavity 111. The two grooves 121 are connected to form a through hole in the middle of the connecting part 120, or the two grooves 121 are connected to form blind holes at the opposite ends of the connecting part 120.

[0039] Specifically, such as Figure 2 As shown, the connecting part 120 has a columnar structure. The columnar structure itself has good mechanical properties, which can stably connect the two opposing inner walls in the cavity 111 of the reagent bottle 100, evenly distribute external forces from different directions, and effectively enhance the overall structural stability of the reagent bottle 100. Moreover, compared with other irregular shapes, the columnar structure is easier to process and form, reducing production difficulty and manufacturing costs.

[0040] The connecting portion 120 has grooves 121 at its opposite ends, and the grooves 121 extend from the outer wall of the bottle body 110 into the cavity 111. In one specific embodiment of this application, as... Figure 2 As shown, the two grooves 121 at opposite ends of the connecting portion 120 extend in opposite directions until they communicate with each other, at which point a through hole is formed in the middle of the connecting portion 120. In another specific embodiment of this application, the two grooves 121 extend in opposite directions until the bottoms of the two grooves 121 connect to form two blind holes (not shown in the figure), at which point the middle of the connecting portion 120 has a connecting surface formed by the bottoms of the grooves 121.

[0041] It should be noted that, in one possible implementation of this application, firstly, as... Figure 2 As shown, the outer diameter of the connecting portion 120 gradually decreases along the depth direction a from the inner wall of the cavity 111. This decrease can occur either from one end of the connecting portion 120 to the other along the depth direction a, or both ends of the connecting portion 120 can have their outer diameters gradually decrease along the depth direction a, resulting in a structure where the connecting portion 120 has a small outer diameter in the middle and a large outer diameter at both ends. This gradual decrease in the outer diameter of the connecting portion 120 facilitates demolding of the integrally molded reagent bottle 100, further improving the preparation efficiency of the reagent bottle 100.

[0042] Second, this application does not impose any restrictions on the specific shape of the connecting part 120. The connecting part 120 can be cylindrical, triangular prism, quadrangular prism, etc. Correspondingly, the cross-section of the connecting part 120 can be any one of circular, polygonal, or elliptical shapes; wherein, the direction of the cross-section is parallel to the direction of the plane on which the inner wall to which the connecting part 120 is connected is located.

[0043] In one possible implementation of this application, such as Figure 2As shown, the bottle body 110 also has a handle 115, the handle 115 has a hollow structure inside, and the cavity 111 is connected to the handle 115; the end of the handle 115 has an air port 1151.

[0044] Specifically, such as Figure 2 As shown, the bottle body 110 has a handle 115. Preferably, the handle 115 is located at the top of the bottle body 110. The handle 115 has a hollow structure inside to communicate with the cavity 111 to form an air passage. One end of the handle 115 is provided with an air port 1151 that communicates with the hollow structure. The air port 1151 is used to balance the air pressure inside the bottle and prevent the bottle body 110 from expanding or collapsing due to air pressure, thereby further improving the stability and reliability of the bottle body 110.

[0045] Optionally, such as Figure 1 As shown, the opening includes a first opening 112 and a second opening 113 respectively disposed on opposite sides of the cavity 111. The first opening 112 is used to add solution into the cavity 111, and the first opening 112 is provided with a detachable cap. When the tissue processing device is not in operation, the detachable cap can be removed to add liquid into the bottle body 110, or the solution in the bottle body 110 can be poured out through the first opening 112. To facilitate the operator to quickly observe the solution volume in the bottle body 110, preferably, an observation area can be provided on the side of the bottle body 110 near the first opening 112, and the observation area is provided with scale lines.

[0046] The second opening 113 is used to connect with the main body of the tissue processing device. The main body of the tissue processing device can pump out the solution in the bottle 110 through the second opening 113, or add the solution that has been reacted in the main body of the tissue processing device back into the bottle 110 through the second opening 113.

[0047] By setting a first opening 112 and a second opening 113 with different functions on the reagent bottle 100, the reagent bottle 100 can simultaneously meet the operations of adding, discharging, and interacting with the equipment. The first opening 112 is dedicated to manual addition and pouring of liquid, which allows the operator to quickly and intuitively complete the replenishment or cleaning of the solution; the second opening 113 is used to connect with the main unit of the tissue processing equipment to realize the automated extraction and reflux of the solution.

[0048] Furthermore, the reagent bottle 100 also includes an infusion tube disposed within the bottle body 110. One end of the infusion tube communicates with the second opening 113, and the other end extends into the bottom of the bottle body 110. The tissue processing device's main unit, through the infusion tube, enables automated extraction and reflux of the solution, while also allowing the main unit to more fully extract the solution from the bottle through the second opening 113. Even when the volume of solution in the bottle is small, the solution can be extracted to the maximum extent, reducing solution residue and improving solution utilization.

[0049] Another aspect of this application embodiment also provides a tissue dehydration device, including a machine body and a reagent bottle 100; a tissue processing cylinder is provided at the upper end of the machine body, the tissue processing cylinder is used to place tissue samples to realize the processing of tissue samples; the reagent bottle 100 can communicate with the tissue processing cylinder through an opening to realize the circulation and drainage of solution.

[0050] Specifically, the tissue dehydration equipment includes a machine body and a reagent bottle 100. The machine body is equipped with a tissue processing cylinder located at the upper end for easy placement and removal of tissue samples by the operator. The reagent bottle 100 is detachably housed within the machine body. To facilitate insertion and removal of the reagent bottle 100, preferably, a handle 116 is provided on the side of the reagent bottle 100 near the first opening 112, allowing the operator to apply force to the reagent bottle 100 for easier insertion and removal. The handle 116 can be a protruding structure integrally formed with the bottle body 110, or a recessed structure formed within the bottle body 110. This application does not impose any restrictions on the specific structure and arrangement of the handle 116, as long as it facilitates the operator's application of force to the reagent bottle 100.

[0051] The operator can add solution to reagent bottle 100 through the first opening 112. Reagent bottle 100 is connected to the tissue processing tank through the second opening 113, thus establishing a solution circulation and drainage channel. During tissue processing, the tissue dehydration equipment can drain the solution from reagent bottle 100 through the second opening 113 to the tissue processing tank according to the needs of different stages, providing the necessary reagents for tissue sample processing. After the tissue sample processing is completed, the waste liquid in the tissue processing tank can be drained back into reagent bottle 100 through the second opening 113 for centralized processing. The operator can disassemble reagent bottle 100 from the tissue dehydration equipment and drain the waste liquid inside through the first opening 112 to prepare for the next processing step.

[0052] The solution circulation and extraction mechanism of the tissue dehydration equipment reduces the number of manual steps involved in adding and replacing solutions, lowering the risk of errors and contamination caused by human intervention, and improving the automation and standardization of the tissue processing. The structure of reagent bottle 100 also enhances the efficiency and reliability of the tissue dehydration equipment. The specific structure and beneficial effects of reagent bottle 100 have been detailed above and will not be repeated here.

[0053] In another aspect, this utility model also provides a tissue processing device, including a body and one or more reagent bottles 100, the body having a reagent compartment, and the one or more reagent bottles 100 being housed in the reagent compartment.

[0054] Specifically, the tissue processing equipment can be a staining machine or an immunohistochemistry instrument, etc. The tissue processing equipment includes a reagent compartment, in which at least one reagent bottle 100 is detachably disposed. To facilitate the insertion and removal of the reagent bottle 100, preferably, a handle 116 is provided on the side of the reagent bottle 100 near the first opening 112, allowing the operator to apply force to the reagent bottle 100 more easily. The handle 116 can be a protruding structure integrally formed with the bottle body 110, or a recessed structure formed in the bottle body 110. This application does not impose any restrictions on the specific structure and arrangement of the handle 116, as long as it facilitates the operator in applying force to the reagent bottle 100.

[0055] The operator can add solution into reagent bottle 100 through the first opening 112, and reagent bottle 100 is connected to the tissue sample reaction area through the second opening 113. Reagent bottle 100 is used to hold the solution, and the tissue processing equipment can pump the solution in reagent bottle 100 into the tissue sample reaction area through the second opening 113 according to the needs of different stages, providing the required reagents for the tissue sample reaction; after the tissue sample reaction has been completed for a preset time, the waste liquid in the tissue sample reaction area can be discharged back into the waste liquid bottle.

[0056] This on-demand supply method ensures that tissue samples receive the appropriate reagents in a timely manner at each processing stage. Simultaneously, the automated extraction process guarantees the accuracy of solution dosage, allowing the tissue samples to react under optimal conditions, thereby improving the quality and effectiveness of tissue processing. After the tissue sample reaction is complete, there is no need for manual transfer of waste liquid, reducing operator contact with waste liquid and lowering the risk of health hazards and environmental pollution. Timely return of waste liquid to the waste bottle maintains the cleanliness of the tissue sample reaction area, preventing residual waste liquid from interfering with subsequent processing steps and ensuring the accuracy and reliability of each processing stage. The structure of reagent bottle 100 also improves the working efficiency and reliability of the tissue processing equipment. The specific structure and beneficial effects of reagent bottle 100 have been detailed above and will not be repeated here.
