Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology and relates to a detachable electric rotating tissue fixation decalcification and rinsing device. Background Technology

[0002] In the field of biomedical research, the fixation and rinsing of experimental tissue specimens are crucial steps in the experimental process. By standardizing the fixation and rinsing procedures, the biological characteristics of tissue specimens can be preserved to the greatest extent, laying the foundation for subsequent morphological observation, molecular detection and other experiments.

[0003] Currently, most existing fixed rinsing devices use centrifuge tubes. However, these devices have several drawbacks. First, the operation is complex. When using centrifuge tubes for rinsing, the tube caps need to be opened and closed frequently, and gauze needs to be tied around the tube openings to prevent tissue from detaching. This not only increases the complexity of the experimental operation but also consumes a lot of manpower. Second, the water flow distribution is uneven. Defects in the structural design of centrifuge tubes prevent the water flow from being evenly distributed to the tissue specimen, easily causing some areas to be over-rinsed while others are under-rinsed, interfering with the accuracy of subsequent experimental results. Third, the tissue sample processing efficiency is low. When dealing with a large number of tissue samples, the lack of an effective water circulation and distribution mechanism makes it difficult for centrifuge tubes to achieve uniform water coverage, resulting in insufficient fixation and decalcification of the tissue samples, thus prolonging the experimental cycle and reducing overall experimental efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a detachable electric rotating tissue fixation and decalcification rinsing device. During tissue fixation and decalcification rinsing, it not only simplifies the operation process and expands the applicability, but also makes the water flow distribution more uniform, avoids insufficient rinsing, and improves rinsing efficiency.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A detachable, electrically operated, rotating tissue fixation and decalcification flushing device includes an experimental tank, comprising:

[0007] The storage box is located on top of the experimental barrel and is rotatably connected to the experimental barrel;

[0008] The rotating shaft is vertically installed inside the experimental barrel, with its upper end passing through the storage box and located at the top of the storage box.

[0009] Multiple processing chambers are vertically arranged inside the experimental barrel and evenly distributed around the rotating shaft. Each processing chamber is connected to the rotating shaft by at least one connecting rod. The upper part of each processing chamber is connected to the storage box through a first connecting pipe. A second connecting pipe is provided at the lower part of each processing chamber. Multiple partitions are horizontally arranged along the vertical direction inside each processing chamber. The multiple partitions divide the interior of the corresponding processing chamber into multiple sample chambers from top to bottom. Each partition has a drain hole.

[0010] A rotating component, located at the upper end of the rotating shaft, is used to drive the rotating shaft to reciprocate.

[0011] The features of this utility model also include:

[0012] The rotating component includes:

[0013] The motor is located at the upper end of the rotating shaft, and the output end of the motor is detachably connected to the upper end of the rotating shaft.

[0014] The motor has a transmission hole at its output end, and the upper end of the shaft is located inside the transmission hole. The cross-section of the upper end of the shaft and the cross-section of the transmission hole are mutually matching polygons.

[0015] The storage box and the experimental container are detachably connected. Each processing chamber has an opening on its side near each sample chamber, and a baffle is installed inside the opening. The baffle and the opening are detachably and sealed together.

[0016] Inside the experimental barrel, a turntable is horizontally positioned below multiple processing chambers. A limiting ring is horizontally positioned below the turntable inside the experimental barrel. The outer edge of the limiting ring is fixedly connected to the inner wall of the experimental barrel, and the upper part of the limiting ring contacts the turntable. A second connecting pipe passes through the turntable and is located below it. The lower end of the rotating shaft is fixedly connected to the turntable.

[0017] The storage tank has a water inlet on top, and the experimental barrel has a water outlet on the side below the turntable.

[0018] A limit groove is provided at the upper part of the storage box near the rotating shaft, with the rotating shaft and the motor located in the limit groove.

[0019] Each baffle has a handle located away from the sample cavity.

[0020] Each of the processing compartments is long and narrow.

[0021] The detachable electric rotating tissue fixation and decalcification flushing device of this utility model has the following advantages:

[0022] This invention simplifies the operation process through the combination of an experimental bucket, a storage box, a rotating shaft, multiple processing chambers, and a rotating component. Water is stored in the storage box when rinsing tissue samples, and then flows into each processing chamber to rinse the samples. This avoids frequent opening and closing of the caps, saving time and labor costs. Simultaneously, the rotating shaft 7 drives the multiple processing chambers to rotate reciprocally, ensuring even water distribution within each chamber. This prevents over- or under-rinsing of the tissue samples, guaranteeing the accuracy of subsequent experimental results. Furthermore, by designing each processing chamber as multiple sample cavities from top to bottom, multiple tissue samples can be processed at once, and the even water distribution within each cavity ensures more thorough fixation and decalcification of the tissue samples, reducing the experimental cycle and improving overall experimental efficiency.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] like Figure 1As shown, this utility model provides a detachable electric rotating tissue fixation decalcification and rinsing device, including a test barrel 1, a storage box 3, a rotating shaft 7, multiple processing chambers 8, and a rotating assembly. The storage box 3 is located on the upper part of the test barrel 1. When it is necessary to rinse the tissue sample, water is stored in the storage box 3. The storage box 3 is rotatably connected to the test barrel 1. The rotating shaft 7 is vertically installed inside the test barrel 1. The upper end of the rotating shaft 7 passes through the storage box 3 and is located on the upper part of the storage box 3. The rotating shaft 7 is fixedly connected to the test barrel 1. Multiple processing chambers 8 are vertically installed inside the test barrel 1. The multiple processing chambers 8 are evenly arranged around the rotating shaft 7. Each processing chamber 8 is elongated. Each processing chamber 8 is connected to the rotating shaft 7 by at least one connecting rod 19. The part is connected to the storage tank 3 through the first connecting pipe 14, so that the water in the storage tank 3 can enter the corresponding processing chamber 8 through the first connecting pipe 14. Each processing chamber 8 is provided with a second connecting pipe 15 at the bottom. Multiple partitions 9 are arranged horizontally along the vertical direction in each processing chamber 8. The multiple partitions 9 divide the interior of the corresponding processing chamber 8 into multiple sample chambers 10 from top to bottom. Each sample chamber 10 is used to place tissue samples. Each partition 9 is provided with a drain hole 16 with a diameter of 5mm, so that the water in the storage tank 3 can enter the processing chamber 8, flow down from the uppermost sample chamber 10, and finally flow out from the second connecting pipe 15. The rotating component is set at the upper end of the rotating shaft 7 and is used to drive the rotating shaft 7 to rotate back and forth. This invention simplifies the operation process through the cooperation of an experimental barrel 1, a storage box 3, a rotating shaft 7, multiple processing chambers 8, and a rotating component. Water is stored in the storage box 3 when rinsing tissue samples, and then flows into each processing chamber 8 to rinse the tissue samples. This avoids frequent opening and closing of the caps, saving time and labor costs. Simultaneously, the rotating shaft 7 drives the multiple processing chambers 8 to rotate reciprocally, ensuring even water distribution within each chamber, preventing over- or under-rinsing of the tissue samples and guaranteeing the accuracy of subsequent experimental results. Furthermore, by designing each processing chamber 8 as multiple sample cavities 10 from top to bottom, multiple tissue samples can be processed at once, and the even distribution of water within each sample cavity 10 ensures more thorough fixation and decalcification of the tissue samples, reducing the experimental cycle and improving overall experimental efficiency.

[0031] like Figure 2 , Figure 3 As shown, the rotating assembly includes a motor 2, which is located at the upper end of the rotating shaft 7, and the output end of the motor 2 is detachably connected to the upper end of the rotating shaft 7.

[0032] like Figure 2 , Figure 3As shown, the output end of motor 2 has a transmission hole 17, and the upper end of rotating shaft 7 is located inside the transmission hole 17. The cross-section of the upper end of rotating shaft 7 and the cross-section of transmission hole 17 are mutually matching polygons. The detachable connection between motor 2 and rotating shaft 7 makes it easy to remove motor 2 when not rinsing. Motor 2 is preferably a stepper motor or a servo motor, which facilitates driving rotating shaft 7 to reciprocate between 0° and 180°, i.e., rotating clockwise and then counterclockwise, and so on.

[0033] like Figure 4 As shown, the storage box 3 is detachably connected to the experimental barrel 1. Each processing chamber 8 has an opening 18 on its side near each sample chamber 10. A baffle 20 is installed inside the opening 18. The baffle 20 is detachably and sealed to the opening 18, so that the storage box 3 can drive the rotating shaft 7 to take the multiple processing chambers 8 out of the experimental barrel 1, and then open the opening 18 on each sample chamber 10 to put the tissue sample into the sample chamber 10.

[0034] like Figure 1 , Figure 4 As shown, a turntable 5 is horizontally positioned below multiple treatment chambers 8 inside the experimental barrel 1. The space below the turntable 5 in the experimental barrel 1 is a water collection chamber 21. A limiting ring 13 is horizontally positioned below the turntable 5 inside the experimental barrel 1. The outer edge of the limiting ring 13 is fixedly connected to the inner wall of the experimental barrel 1. The upper part of the limiting ring 13 contacts the turntable 5. The second connecting pipe 15 passes through the turntable 5 and is located below the turntable 5, that is, the lower end of the second connecting pipe 15 is located in the water collection chamber 21. The lower end of the rotating shaft 7 is fixedly connected to the turntable 5. The limiting ring 13 supports the turntable 5, making the turntable 5 more stable during rotation.

[0035] like Figure 1 As shown, the storage tank 3 has an inlet 11 on its top, and the experimental barrel 1 has an outlet 12 on its side below the turntable 5. The outlet 12 is connected to the water collection chamber 21. The inlet 11 and the outlet 12 are respectively equipped with valves to facilitate the water to be sent into the storage tank 3 for storage during rinsing and to discharge the rinsed water through the outlet 12.

[0036] like Figure 1 , Figure 2 As shown, a limiting groove 6 is provided on the upper part of the storage box 3 near the rotating shaft 7. The rotating shaft 7 is located in the limiting groove 6, and the motor 2 is located in the limiting groove 6. The limiting groove 6 makes the storage box 3 more stable when rotating.

[0037] like Figure 4 As shown, each baffle 20 is provided with a handle 4 at a position away from the sample cavity 10, which facilitates the opening and closing of the opening 18 of the baffle 20.

[0038] Each sample chamber 10 is 30mm high to ensure sufficient space to accommodate tissue samples of different sizes. Each baffle 20 has a label slot on the side away from the sample chamber 10. The sample information is recorded by the label and the label is placed in the label slot to distinguish the tissue samples in each sample chamber 10.

[0039] Working principle: When in use, the storage box 3 drives the rotating shaft 7 to take out multiple processing chambers 8 from the experimental bucket 1, open the opening 18 on each sample chamber 10, and put a tissue sample into the sample chamber 10 for fixation.

[0040] When it is necessary to rinse the tissue sample, open the valve of the inlet 11 to send water into the storage tank 3 for storage, and then start the motor 2. The motor 2 drives the rotating shaft 7 to rotate back and forth within the range of 0° to 180°. The water in the storage tank 3 enters the corresponding processing chamber 8 through each first connecting pipe 14, flows down from the uppermost sample chamber 10, and finally flows into the water collection chamber 21 through the second connecting pipe 15 at the bottom of each processing chamber 8. Driven by the rotating shaft 7, the water is evenly distributed in each sample chamber 10 to clean the tissue sample. When there is too much water in the water collection chamber 21, open the valve of the outlet 12 to discharge the water through the outlet 12.

[0041] When tissue samples need to be decalcified, the motor 2 is removed from the limiting groove 6, the valve of the inlet 11 is opened, and the valve of the outlet 12 is closed to deliver the decalcification solution into the storage tank 3. The decalcification solution in the storage tank 3 enters the corresponding processing chamber 8 from each first connecting pipe 14, flows down from the uppermost sample chamber 10, and enters each sample chamber 10 to decalcify the tissue samples inside.

[0042] The detachable electric rotating tissue fixation decalcification and rinsing device of this utility model has the following other advantages:

[0043] First, the structural design of multiple first connecting tubes and individual sample chambers ensures that the water flow can evenly cover the tissue sample, achieving comprehensive and thorough rinsing of the tissue sample, improving the fixation effect, and at the same time, making the uniformity of water flow coverage greater than 95%.

[0044] Secondly, this utility model is applicable to pathology departments, biological laboratories, and medical education settings, significantly improving the level of experimental standardization and resource utilization efficiency.

[0045] Third, the detachable design of the motor and shaft makes the fixation and rinsing of tissue specimens more convenient and efficient, greatly reducing the operation time and labor intensity of laboratory personnel.

[0046] Fourth, this device can not only be used for tissue specimen fixation and rinsing, but also for tissue decalcification, making it a multi-purpose device that improves the utilization efficiency of laboratory equipment.

[0047] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
