Description

Technical Field

[0001] This utility model relates to the field of pathological sectioning technology, and more specifically, to a tissue specimen washing device for pathological sampling. Background Technology

[0002] Pathological sections are thin slides, only 3-5 micrometers thick, produced by fixing, dehydrating, embedding, sectioning, and staining diseased tissue. These slides allow for microscopic observation of cell morphology and structure, aiding in disease diagnosis. The core objective is to provide pathologists with direct cytological evidence, clarifying the nature of the lesion (e.g., inflammation, tumor) and the extent of disease progression. Before preparing pathological sections, the tissue blocks must be thoroughly cleaned of blood, dirt, mucus, food, feces, and other impurities that could affect preparation and observation.

[0003] Chinese Patent Publication No. CN220188172U discloses a tissue specimen rinsing device for animal pathological sampling. This design involves placing a rinsing basket within the water-filling space of a rinsing tank, and placing the tissue specimen within the rinsing space of the basket. This avoids loss and confusion of tissue specimens during the sampling process, while ensuring that the tissue specimen is rinsed during sampling, reducing contamination, protecting the health of testing personnel, and improving work efficiency, thus achieving a scientific and efficient sampling process. However, in practical implementation, the following drawbacks exist: When rinsing animal pathological samples, many tissues must be placed in the same rinsing tank simultaneously, which can lead to contact between infectious agents or substances on different samples. This cross-transfer may cause adverse reactions, affecting the accuracy of subsequent slide observation.

[0004] Therefore, a tissue specimen washing device for pathological sampling is proposed to address the above problems. Utility Model Content

[0028] Example

[0029] Please see Figure 1-5 A tissue specimen rinsing device for pathological sampling includes a water receiving tray 1, a drain pipe 2 fixedly connected to the inner surface of the right side of the water receiving tray 1, a support 3 fixedly connected to the bottom wall of the inner cavity of the water receiving tray 1, a rinsing mechanism 4 fixedly connected to the upper end of the support 3, the rinsing mechanism 4 includes four partitions 41, a rinsing component 42 fixedly connected to the upper end of the four partitions 41, a trapezoidal plate 43 fixedly connected to the lower end of the four partitions 41, the left and right ends of the trapezoidal plate 43 being fixedly connected to the left and right walls of the inner cavity of the support 3 respectively, and five shaking components 44 fixedly connected to the bottom wall of the inner cavity of the trapezoidal plate 43, each of the five shaking components 44 having a placement component 45 slidably connected inside.

[0030] This solution utilizes the rinsing mechanism 4 to quickly rinse pathological tissues, effectively removing impurities such as blood, dirt, mucus, food, and feces that could affect preparation and observation. Five placement components 45, working in conjunction with the rinsing component 42, allow for the rinsing of five different animal pathological tissues at a time, significantly improving rinsing efficiency while effectively preventing cross-reactions between tissues. Five shaking components 44 continuously change the position of the pathological tissues during rinsing, resulting in better and more thorough rinsing. The drain pipe 2, in conjunction with the water collection tray 1, allows for the centralized discharge of waste liquid generated during rinsing. The sliding connection between the placement components 45 and the shaking components 44 facilitates quick and easy removal of the placement components 45 for cleaning.

[0031] Please see Figure 2-5The rinsing assembly 42 includes a water tank 421. The lower end of the water tank 421 is fixedly connected to the upper end of the bracket 3. A water injection pipe 422 is fixedly connected to the upper end of the water tank 421. A water pump 423 is fixedly connected to the right end of the water tank 421 through a connecting pipe. The lower end of the water pump 423 is fixedly connected to the upper end of the bracket 3. A water outlet pipe 424 is fixedly connected to the right end of the water pump 423. A diversion pipe 425 is fixedly connected to the left end of the water outlet pipe 424. The upper end of the diversion pipe 425 is fixedly connected to the lower end of the bracket 3. Five rinsing heads 426 are fixedly connected to the inner surface of the diversion pipe 425.

[0032] The placement component 45 includes a placement tube 451, an opening plate 452 is fixedly connected to the inner surface of the placement tube 451, and an insertion rod 453 is fixedly connected to the lower end of the opening plate 452.

[0033] The shaking assembly 44 includes a motor 441. The lower end of the motor 441 is fixedly connected to the bottom wall of the inner cavity of the trapezoidal plate 43. The output end of the motor 441 is fixedly connected to a worm gear 442 via a coupling. A worm wheel 443 is meshed with the outer surface of the worm gear 442. A rotating rod 444 is fixedly connected to the inner surface of the worm wheel 443. Two bearings 448 are fixedly connected to the outer surface of the rotating rod 444. The outer surfaces of several bearings 448 are fixedly connected to the inner surface of the trapezoidal plate 43. An electric push rod 445 is fixedly connected to the upper end of the rotating rod 444. A slot 446 is opened at the upper end of the electric push rod 445. The inner surfaces of the five slots 446 are slidably connected to the outer surfaces of the five insert rods 453 respectively. A flow guide 447 is fixedly connected to the outer surface of the worm gear 442.

[0034] This method involves placing the animal pathological tissues to be rinsed into five placement tubes 451, restricting tissue displacement through the perforations of the perforated plate 452 to prevent clogging, inserting the insertion rod 453 into the slot 446 of the shaking assembly 44 to connect the placement tubes 451 to the electric push rod 445, injecting clean water or cleaning solution into the water tank 421 through the water injection pipe 422, activating the water pump 423, and distributing the water through the diversion pipe 425 to the five rinsing heads 426 to rinse the samples in the lower placement tubes 451.

[0035] By synchronously starting the motor 441 and the electric push rod 445, the motor 441 drives the worm gear 442 to rotate, which in turn drives the worm wheel 443 and the rotating rod 444 to rotate. At the same time, the electric push rod 445 periodically extends and retracts, allowing the pathological tissue in the placement tube 451 to jump vertically and rotate around the axis, continuously changing the contact surface between the pathological tissue and the clean water or cleaning solution, resulting in a better rinsing effect. After rinsing, the waste liquid is collected in the water receiving tray 1 and discharged through the drain pipe 2, which is quite convenient.

[0036] It should be noted that, in the specific implementation process, solenoid valves can be installed on the five rinsing heads 426, so that the number of rinsing heads 426 used can be adjusted according to the number of animal pathological tissues that need to be rinsed, thus avoiding waste of water.

[0037] It should be noted that the specific installation methods, circuit connection methods, oil circuit connection methods, and control methods of the water pump 423, motor 441, and electric push rod 445 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0038] Working principle: When the device is needed to rinse pathological tissue, the pathological tissue is first placed in the placement tube 451. Then, the placement tube 451 is connected to the electric push rod 445 through the cooperation of the insertion rod 453 and the slot 446. After the connection is completed, the water pump 423 is started, which pumps the cleaning solution or clean water in the water tank 421 into the diversion pipe 425 through the water outlet pipe 424. The diversion pipe 425 is used to divert the cleaning solution or clean water to five rinsing heads 426. At this time, each rinsing head 426 will rinse the pathological tissue in the placement tube 451 directly below. Through the correspondence between the rinsing head 426 and the placement tube 451, and in cooperation with the four partitions 41, each pathological tissue can be cleaned independently, which can effectively prevent different pathological tissues from coming into contact with each other and being contaminated with substances that do not belong to them.

[0039] To improve the rinsing effect of the device, the motor 441 and the electric push rod 445 can be started simultaneously during the rinsing process. The electric push rod 445 continuously extends and retracts, causing the worm gear 442 to drive the worm wheel 443 to rotate under the action of the motor 441. This causes the rotating rod 444 to rotate under the combined action of the worm wheel 443 and the two bearings 448. As a result, the electric push rod 445 rotates while extending and retracting. At this time, the pathological tissue located in the placement tube 451 will continuously jump under the action of the electric push rod 445 to change its position in contact with the liquid, so that the pathological tissue can be rinsed more thoroughly.

[0040] During the cleaning process, the cleaning waste liquid will flow down the perforated plate 452, and after being guided by the guide shroud 447, it will flow directly into the water receiving tray 1 along the surface of the trapezoidal plate 43, which facilitates the discharge of waste liquid.

[0041] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
