Description

Technical Field

[0001] This utility model relates to the field of decalcification instruments, and in particular to a decalcification instrument. Background Technology

[0002] In medical pathology research and diagnosis, decalcification of calcium-containing tissue specimens is a crucial step. When preparing sections, calcium-containing tissues, such as bone, are frequently encountered. The calcium in these tissues is very hard and has a different density than paraffin, so they generally cannot be directly sectioned. Furthermore, other tissues besides bone can also calcify, forming calcified areas. These calcified tissues also require decalcification for pathological research or diagnosis to facilitate sectioning and observation. Generally, a corresponding decalcification solution is prepared for each type of tissue sample. Decalcification is achieved by immersing the tissue sample in the solution for an extended period. However, traditional decalcification methods suffer from problems such as long decalcification times and uneven decalcification, affecting the accuracy of subsequent tissue section observation and diagnosis. In addition, the decalcification process generates an odor, causing discomfort to operators and posing a risk of environmental pollution. Utility Model Content

Detailed Implementation

[0036] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0037] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] refer to Figure 1-5 An embodiment of this utility model illustrates a decalcification device, comprising a body 1, a liquid storage container 2, a sample container 3, a rotation drive mechanism 6, a lateral movement drive mechanism 4, and a lifting drive mechanism 5; the liquid storage container 2 is disposed within the body 1 and is used to store decalcification liquid; the sample container 3 is used to store tissue samples and has multiple perforated holes (not marked in the figure); the rotation drive mechanism 6 is used to drive the sample container 3 to rotate around a vertical axis; the lateral movement drive mechanism 4 is used to drive the sample container 3 to move laterally; and the lifting drive mechanism 5 is used to drive the sample container 3 to move vertically.

[0041] Specifically, the sample container 3 moves in space through the transverse drive mechanism 4 and the lifting drive mechanism 5, so that the sample container 3 can be immersed in the liquid storage container 2 and leave the liquid storage container 2; while the rotation drive mechanism 6 can make the sample container 3 rotate in the liquid storage container 2.

[0042] In application, sample container 3 is positioned above (not necessarily directly above) the liquid storage container 2. After the tissue sample is placed in sample container 3, the lateral movement drive mechanism 4 moves sample container 3 laterally, aligning sample container 3 vertically with the liquid storage container 2. Then, the lifting drive mechanism 5 lowers sample container 3, allowing at least a portion of sample container 3 to enter the liquid storage container 2. The decalcification solution in the liquid storage container 2 enters sample container 3 through the perforated holes, allowing the tissue sample to contact and react with the decalcification solution. During soaking, sample container 3 can be rotated by rotation drive mechanism 6 or raised and lowered by lifting drive mechanism 5, ensuring that the tissue sample in sample container 3 is fully soaked. This avoids the situation where tissue samples are stacked, resulting in some tissue samples not being fully decalcified, thereby improving decalcification efficiency and uniformity.

[0043] In the above-mentioned scheme, the tissue sample in the decalcification solution is not stirred by a stirring component, which can avoid the tissue sample being broken or damaged by the stirring component. In this embodiment, the tissue sample is placed in the sample container 3, and then the sample container 3 is driven to move by the lifting drive mechanism 5 and the rotating drive mechanism 6, so as to achieve full contact reaction between the tissue sample and the decalcification solution in a gentler way.

[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, the machine body 1 contains an experimental chamber 11, within which the liquid storage container 2, sample container 3, rotary drive mechanism 6, lateral drive mechanism 4, and lifting drive mechanism 5 are all housed. The machine body 1 also includes a purification system 7, which is connected to the experimental chamber 11 to filter and purify the air within it. This purification system 7 effectively filters and purifies the air within the experimental chamber 11, promptly eliminating odors generated during the decalcification process, reducing the leakage of chemical gases to the outside of the instrument, preventing discomfort for operators, and minimizing environmental pollution.

[0045] In some more specific embodiments, such as Figure 5 As shown, the purification system 7 includes an air handling module 71, an air inlet duct 72, and an air supply duct 73. The air handling module 71 includes a housing 711, within which a fan 712 and an air filter assembly 713 are disposed. One end of the air inlet duct 72 is connected to the experimental chamber 11, and the other end is connected to the housing 711. One end of the air supply duct 73 is connected to the experimental chamber 11, and the other end is connected to the housing 711. The experimental chamber 11, the air inlet duct 72, the housing 711, and the air supply duct 73 sequentially form an air circulation path, and the air filter assembly 713 is located on the air circulation path.

[0046] The experimental chamber 11 is equipped with an air inlet 111 and an air outlet 112. An air inlet duct 72 connects to the experimental chamber 11 through the air inlet 111, and an air outlet duct 73 connects to the experimental chamber 11 through the air outlet 112. A fan 712 provides the power for airflow, drawing air from the experimental chamber 11 into the air handling module 71 through the air inlet duct 72. The air is then filtered and purified by an air filter assembly 713 inside the air handling module 71, trapping odor molecules. The purified air is then reintroduced into the experimental chamber 11 through the air outlet duct 73. In this embodiment, the air filter assembly 713 uses a high-efficiency composite filter; in other embodiments, other filter materials may be used without limitation.

[0047] In some embodiments, such as Figure 5 As shown, the system also includes a temperature control system 8, which comprises a temperature sensor 82 and a heater 81. The heater 81 is disposed on the air circulation path. In this embodiment, the heater 81 is disposed inside the housing 711, and the temperature sensor 82 is disposed on the air inlet duct 72. In this embodiment, the heater 81 is a PTC heater. The temperature sensor 82 detects the air temperature, and the heater 81 heats the air to adjust it to a preset temperature, thus maintaining the temperature inside the experimental chamber 11 at a suitable level for decalcification treatment.

[0048] In some embodiments, to facilitate the movement of the sample container 3, such as Figure 2 and Figure 4 As shown, the transverse drive mechanism 4 is a horizontally arranged screw transmission module, which is fixedly mounted on the machine body 1, and a first movable seat 41 is provided on the transverse drive mechanism 4; the lifting drive mechanism 5 is a vertically arranged screw transmission module, which is mounted on the first movable seat 41, and a second movable seat 51 is provided on the lifting drive mechanism 5; the rotation drive mechanism 6 is mounted on the second movable seat 51, and the rotation drive mechanism 6 includes a motor 61 and a rotating body 62 driven by the motor 61 to rotate, and the rotating body 62 is connected to the sample container 3.

[0049] In this embodiment, the sample container 3 is a hanging basket with multiple hollow holes, and the sample container 3 is suspended on the rotating body 62; the rotating body 62 can be any structure such as a rod, a hanger, or a hook.

[0050] In some embodiments, to prevent decalcification solution from splashing into the experimental chamber 11 and causing contamination when the sample container 3 is rotated, such as... Figure 2 and Figure 4As shown, the experimental chamber 11 is equipped with a removable splash guard 9, and the liquid storage container 2 is disposed within the splash guard 9. Thus, when the decalcification solution splashes out from the liquid storage container 2, the decalcification solution can fall into the splash guard 9. After the decalcification process is completed, the splash guard 9 can be removed for cleaning, facilitating instrument maintenance.

[0051] Preferably, multiple liquid storage containers 2 are provided, and the multiple liquid storage containers 2 are arranged in the anti-splash tank 9 along the lateral driving direction of the lateral driving mechanism 4. Furthermore, a sponge can be placed in the anti-splash tank 9 to fix the position of the liquid storage containers 2, while also absorbing the decalcification liquid that falls into the anti-splash tank 9.

[0052] In some embodiments, such as Figure 1 As shown, one side of the body 1 is provided with a door 12 for opening the experimental chamber 11, which facilitates the handling of tissue samples, decalcification solution and other operations.

[0053] In addition, the body 1 is provided with a transparent observation window 13, through which the decalcification situation in the experimental chamber 11 can be observed; in this embodiment, the transparent observation window 13 is located on the top of the body 1; in other embodiments, the transparent observation window 13 can also be located in other positions, as long as it is convenient for the operator to observe.

[0054] In summary, this utility model provides a decalcification instrument that allows the sample container 3 to move up and down and rotate within the liquid storage container 2, ensuring that the tissue sample in the sample container 3 fully contacts the decalcification solution in the liquid storage container 2. This avoids situations where some tissue samples cannot fully contact and react with the liquid storage container 2, thereby improving decalcification efficiency and uniformity.

It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
