Description

Technical Field

[0001] This utility model relates to the field of pathological specimen processing technology, specifically to an auxiliary soaking device for pathological specimens. Background Technology

[0002] Pathological specimens are crucial basic materials in medical diagnosis. Through the analysis of human tissues, cells, or body fluids, they provide core evidence for disease diagnosis, treatment planning, and prognostic assessment. Pathological specimens include surgically removed tissues, biopsy samples, and biological samples collected from body fluids (such as sputum and pleural effusion). Typically, after collection, tissue samples need to be soaked to stabilize the morphology, structure, and biological components (such as proteins and nucleic acids) of tissue cells using chemical reagents, preventing autolysis, putrefaction, or degradation, and providing qualified basic materials for subsequent sectioning, staining, and molecular detection. Chinese patent document CN211825340U discloses a pathological specimen soaking device. This device involves placing pathological tissue into a soaking tank, fastening the top cover to the tank, and then rotating a handle. The top cover is secured by a threaded rod connected to an inner rod, providing a more stable fixation and protection against damage during storage, thus preventing interference with subsequent pathological diagnosis. However, when the tissue density of the pathological specimen is less than that of the soaking liquid, the tissue sample will float on the surface of the soaking liquid. This not only prevents the pathological specimen from being fully and adequately soaked in the liquid, affecting the soaking effect, but also causes the upper surface of the tissue to be exposed to the air during the soaking process, resulting in structural damage, epidermal drying, and other problems, leading to subsequent detection errors. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide an auxiliary soaking device for pathological specimens. This device can ensure that the pathological tissues are in complete and sufficient contact with the soaking solution, avoid the problem of the pathological tissues floating on the surface of the soaking solution, and improve the soaking effect.

[0004] The objective of this utility model is achieved through the following technical solution: A pathological specimen immersion aid device includes an immersion chamber, an immersion assembly, and a control assembly. The immersion assembly is disposed within the immersion chamber and includes an immersion basket, a sliding plate, a movable cover, and connecting rods. The top surface of the immersion basket is uncovered, and its side walls and bottom surface have uniformly distributed through holes. Positioning plates are fixedly installed on the front and rear inner walls of the top surface of the immersion basket. A movable cover is rotatably installed on the left and right inner walls of the top surface of the immersion basket, located between the positioning plates. A through hole is uniformly distributed in the center of the movable cover. The sliding plate is slidably disposed within the immersion chamber, and its two ends are connected to the corresponding movable covers via connecting rods. The two ends of the connecting rods are rotatably connected to the sliding plate and the movable cover, respectively. The control assembly includes a portal frame, a lifting plate, a screw, and a drive rod. The portal frame is disposed on the top surface of the immersion chamber, and the lifting plate is slidably disposed on its inner wall. The lifting plate is driven by the screw, and two drive rods are rotatably installed on its bottom surface corresponding to the two positioning plates. The bottom end of the drive rod passes through the immersion chamber and the corresponding positioning plate in sequence and is rotatably connected to the top surface of the sliding plate.

[0005] Based on further optimization of the above scheme, an inlet pipe and an outlet pipe are respectively installed on both sides of the soaking tank, and the height of the inlet pipe is greater than the height of the outlet pipe, which is used to control the inflow and drainage of the soaking liquid; electromagnetic valves are respectively installed on the inlet pipe and the outlet pipe.

[0006] Based on further optimization of the above scheme, a material inlet is provided on the top surface of the soaking tank and located between the two drive rods, and the material inlet is sealed by a rubber sealing plug.

[0007] Based on further optimization of the above scheme, a sealing strip is provided on the side of the movable cover away from the side wall of the soaking basket.

[0008] Based on further optimization of the above scheme, positioning ears are fixedly installed on the two outer walls of the positioning plate on the top surface of the soaking basket, and an auxiliary rod is fixedly installed on the top surface of the positioning ears. The end of the auxiliary rod away from the positioning ears passes through the top surface of the soaking tank and is fixedly installed with a limiting block for limiting the movement of the soaking basket during the lifting and lowering process.

[0009] Based on the further optimization of the above scheme, a through hole is opened in the middle of the auxiliary rod, and a positioning pin is set in the through hole. The descent of the soaking basket is hard-limited by inserting the positioning pin into the corresponding through hole.

[0010] Based on further optimization of the above scheme, square through slots are respectively provided on both sides of the sliding hole of the positioning plate corresponding to the drive rod, and lifting blocks are respectively provided on both sides of the outer wall of the drive rod.

[0011] The following are the technical effects of this utility model: This application utilizes a control assembly consisting of a portal frame, a lifting plate, a screw, and a drive rod to drive a sliding plate to move up and down. The downward movement of the sliding plate, in conjunction with a connecting rod, pulls the movable cover to rotate, thereby closing the soaking basket. Subsequently, the continuous downward movement of the sliding plate pushes the soaking basket into the soaking solution. The closed movable cover rigidly limits the upward movement of the pathological specimen tissue, effectively preventing the tissue surface from being exposed to air, which could lead to insufficient soaking, structural damage, and epidermal drying. At the same time, by evenly spaced through holes in the movable cover, it is effectively ensured that the soaking solution can flow in from the top surface of the soaking basket, further guaranteeing sufficient and uniform contact between the tissue and the soaking solution.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: A pathological specimen immersion aid device includes an immersion tank 10, an immersion assembly, and a control assembly. The immersion tank 10 has two sides (i.e., Figure 1 The left and right sides (as shown) are respectively equipped with an inlet pipe 11 and an outlet pipe 12, and the height of the inlet pipe 11 is greater than the height of the outlet pipe 12 (e.g., Figure 1As shown, the left side is the inlet pipe 11 and the right side is the outlet pipe 12 (the height of the outlet pipe 12 is lower than the bottom surface of the initial position of the soaking basket 21), used to control the inflow and drainage of the soaking liquid; electromagnetic valves (conventional electromagnetic control valves in the art can be used) are respectively installed on the inlet pipe 11 and the outlet pipe 12. The soaking assembly is set in the inner cavity of the soaking tank 10, including the soaking basket 21, the sliding plate 22, the movable cover 23 and the connecting rod 24. The top surface of the soaking basket 21 is uncovered and its side walls and bottom surface are evenly opened with through holes (e.g., Figure 4 As shown, a portion of the top side wall of the soaking basket 21 is left without through holes, serving as a supporting structure. Positioning plates 211 are fixedly installed on the inner walls of the top front and rear ends of the soaking basket 21. Figure 2 The front and back ends are shown. Figure 1 (as shown on the left and right ends), the inner walls of the left and right sides of the top surface of the soaking basket 21 (i.e., Figure 2 The left and right sides shown Figure 1 The movable cover 23 (as shown in the front and rear sides) is rotatably mounted between the positioning plates 211. Figure 2 As shown, the movable cover 23 is fixedly sleeved on the outer wall of the rotating shaft on the side near the soaking basket 21. The rotating shaft is rotatably set in a rotating groove opened on the top surface of the corresponding side wall of the soaking basket 21, thereby realizing the rotatable connection between the movable cover 23 and the soaking basket. Through holes are evenly opened in the middle of the movable cover 23 (e.g., ...). Figure 4 As shown), a sealing strip is provided on the side of the movable cover 23 away from the side wall of the soaking basket 21 (e.g. Figure 2 , Figure 3 (As shown); the sliding plate 22 is slidably disposed in the inner cavity of the soaking basket 21 (vertical protrusions are respectively provided in the middle of the four side walls of the inner cavity of the soaking basket 21, and the four side walls of the sliding plate 22 are correspondingly opened) and its end face is respectively connected to the corresponding movable cover 23 (bottom surface) through connecting rods 24, and the two ends of the connecting rods 24 are respectively rotatably connected to the sliding plate 22 and the movable cover 23 (as shown). Figure 2 , Figure 3 As shown, the two ends of the connecting rod 24 are rotatably connected by bearings.

[0019] The control components include a portal frame 31, a lifting plate 32, a screw 33, and a drive rod 34. The portal frame 31 is mounted on the top surface of the soaking tank 10, and the lifting plate 32 is slidably mounted on its inner wall (a vertical groove is formed in the inner wall of the portal frame 31, and lifting sliders are set at both ends of the lifting plate 32 corresponding to the vertical grooves. The lifting sliders are slidably engaged in the corresponding vertical grooves, thereby realizing the up-and-down sliding of the lifting plate 32 inside the portal frame 31). The lifting plate 32 is driven by the screw 33 (e.g., ...). Figure 1As shown, a screw rod 33 is respectively installed on the inner side of the portal frame 31, and the upper and lower ends of the screw rod 33 are rotatably connected to the top of the portal frame 31 and the top surface of the soaking tank 10, respectively. The screw rod 33 passes through the lifting plate 32 and is threadedly connected. Two drive rods 34 are rotatably installed on the bottom surface of the two positioning plates corresponding to the screw rod 33. The bottom end of the drive rod 34 passes through the top surface of the soaking tank 10 and the corresponding positioning plate 211 in sequence, and is rotatably connected to the top surface of the sliding plate 22. A material inlet 13 is set on the top surface of the soaking tank 10 and between the two drive rods 34. The material inlet 13 is sealed by a rubber sealing plug.

[0020] Positioning lugs 212 are fixedly installed on the top surface of the soaking basket 21, corresponding to the two outer walls of the positioning plate 211. Figure 1 As shown), an auxiliary rod 213 is fixedly installed on the top surface of the positioning lug 212. One end of the auxiliary rod 213, away from the positioning lug 212, passes through the top surface of the soaking tank 10 and is fixedly fitted with a limiting block 2132 for limiting the movement of the soaking basket 21 during its lifting and lowering process. A through hole 2131 is opened in the middle of the auxiliary rod 213, and a positioning pin is installed inside the through hole 2131. The hard limit of the descent of the soaking basket 21 is achieved by inserting the positioning pin into the corresponding through hole 2131. Square through slots (such as...) are respectively provided on both sides of the sliding hole of the driving rod 34 on the positioning plate 211. Figure 4 As shown), lifting blocks 340 are correspondingly installed on both sides of the outer wall of the drive rod.

[0021] Working principle: In use, first close the outlet pipe 12 and open the inlet pipe 11 to introduce soaking liquid into the soaking tank 10. When the soaking liquid reaches the specified amount (real-time monitoring of the amount of soaking liquid is achieved by setting a liquid level sensor in the soaking tank 10 or setting a scale in the soaking tank 10), close the inlet pipe 11. Then, place the pathological specimen onto the sliding plate 22 through the material inlet 13 and seal the material inlet with a rubber sealing plug. After that, start the screw 33 to rotate (the screw 33 can be driven to rotate by a motor set on the end face of the gantry bracket 31), driving the lifting plate 32 to move down. The lifting plate 32 drives the sliding plate 22 to move down through the drive rod 34 (during this process, because the positioning pin is inserted into the corresponding through hole 2131 and the auxiliary rod 231 does not move down, the soaking basket 21 does not move down). During the downward movement of the sliding plate 22, the movable cover 23 is pulled to rotate through the connecting rod 24, thereby closing the top surface of the soaking basket 10 until the sliding plate 22 is at the bottom of the soaking basket 10 (e.g., Figure 3As shown; during this process, the lifting block 340 passes through the corresponding square through slot and is located below the positioning plate 211. The drive rod 34 is rotated to achieve the hard limit of the sliding plate 22, and then the hard limit of the rotation of the movable cover 23, pausing the rotation of the screw 33; then, the corresponding positioning pin is pulled out, the hard limit of the auxiliary rod 213 is released, and the screw 33 is driven to rotate again, thereby causing the soaking basket 21 to move down as a whole to achieve soaking; during the soaking process, the floating pathological specimen is limited by the closed movable cover 23.

[0022] Example 2: As a further optimization of the present invention, based on the solution of embodiment 1, in order to ensure the uniformity of the soaking solution, two sets of rotating blades are rotatably arranged on the bottom surface of the inner cavity of the soaking tank 10. The two sets of rotating blades are symmetrically arranged and the rotating blades face the center of the soaking tank 10. Thus, by rotating the blades, the soaking solution is uniformly mixed and the soaking solution is ensured to flow to the pathological specimen in the soaking basket.

[0023] Example 3: As a further optimization of the present invention, based on the embodiment 1, a groove is provided on the top surface of the sliding plate 22 between the two connecting rods 24 and the two driving rods 34 for the initial placement of pathological tissue.
