Description

Technical Field

[0001] This utility model relates to the field of magnetic field shielding technology, specifically to a magnetic shielding cabin. Background Technology

[0002] With the continuous development of medical technology, the study of the influence of magnetic fields on the entire biological growth cycle has gradually attracted attention. To avoid the impact of geomagnetic signals on the accuracy of research data, biological cell culture dishes are usually placed in magnetically shielded chambers to isolate geomagnetic signals and provide a non-magnetic growth environment for the biological cells. However, currently, magnetically shielded chambers are mostly used to provide an interference-free testing environment for the wireless communication equipment under test, without considering the airtightness of the magnetic shielding chamber. Therefore, substances in the external environment, such as moisture, can easily enter the interior of the magnetically shielded chamber, interfering with the research on biological cells. Utility Model Content

[0003] In view of this, the present invention provides a magnetic shielding chamber to solve the problem that the poor sealing performance of current magnetic shielding chambers affects the accuracy of biological cell research data.

[0004] This utility model provides a magnetic shielding chamber, comprising:

[0005] The cabin includes an empty cabin and a hatch connected to the empty cabin, and the hatch is surrounded by an annular protrusion.

[0006] The hatch has an annular groove that mates with the annular protrusion. The hatch is positioned within the annular groove through the annular protrusion and fits snugly against the cabin body.

[0007] Beneficial effects: This invention provides space for storing biological cells by setting up an empty compartment within the main chamber, meeting the needs of relevant scientific research or experiments for storing biological cells and providing a good foundation for the research and cultivation of biological cells. Secondly, the hatch on the main chamber connects to the empty compartment, facilitating the placement and removal of biological cells by operators, improving operational convenience. Furthermore, the closure and sealing of the hatch ensures the airtightness of the empty compartment throughout the entire experimental process.

[0008] Furthermore, by incorporating annular grooves and protrusions between the cabin and the hatch, the hatch can be correctly aligned with the cabin, reducing installation errors and avoiding sealing problems caused by positional misalignment. In addition, compared to simple flat fitting, the annular protrusion inserted into the annular groove makes the path for external substances, such as moisture, to penetrate the magnetically shielded cabin more complex. This means that the probability of external substances overcoming the combined obstruction created by the annular protrusion and groove to enter the cabin is significantly reduced. This improves the sealing performance of the magnetically shielded cabin, ensuring that the internal environment is not disturbed by external substances, providing a stable and reliable environmental guarantee for the smooth conduct of experiments.

[0009] In one optional embodiment, both the cabin body and the hatch include a stacked shielding layer and a conductive layer; springs are provided on the surfaces of the annular groove and the annular protrusion facing each other, and in the closed state, the conductive layer on the cabin body is connected to the conductive layer on the hatch through the springs.

[0010] Beneficial effects: Through the layered shielding and conductive layers, the cabin and hatch can block external magnetic fields from interfering with the internal space. Specifically, the shielding layer typically has high magnetic permeability, which guides external magnetic fields around the protected area, reducing the impact of external magnetic fields on the internal environment of the magnetically shielded cabin. The conductive layer can isolate high-frequency magnetic fields through electromagnetic induction, effectively isolating and weakening external magnetic fields. Furthermore, the conductive layer on the cabin body is connected to the conductive layer on the hatch door via spring contacts, forming a continuous and complete conductive barrier. This enhances the electromagnetic shielding performance at the junction of the cabin body and hatch door, ensuring the integrity of the magnetic shielding.

[0011] In one optional embodiment, the shielding layer and the conductive layer are both at least one and are alternately arranged, with a filling layer provided between adjacent shielding layers and conductive layers.

[0012] Beneficial effects: The filling layer plays a supporting and insulating role. Its presence can ensure that the shielding layer and the conductive layer maintain an appropriate distance, avoiding short circuits caused by excessive distance between them. At the same time, it can also prevent electrochemical reactions between them under the influence of external moisture, thus ensuring the stability and safety of the entire magnetic shielding structure.

[0013] In one optional embodiment, the empty chamber is equipped with a cell culture device, and an electromagnetic coil is installed in the side wall of the chamber, with the electromagnetic coil located around the cell culture device.

[0014] Beneficial effects: The electromagnetic coils placed around the cell culture device can generate a uniform magnetic field inside the chamber, thus enabling experiments on the effects of magnetic fields on cell function to be carried out inside the magnetically shielded chamber.

[0015] In one optional embodiment, the cell culture device includes a plurality of culture panels for placing cell culture dishes. The plurality of culture panels are disposed in the empty chamber and spaced apart along the height direction of the chamber, and are slidably connected to the inner wall of the chamber. The sliding direction of the culture panels is consistent with the orientation of the chamber opening.

[0016] Beneficial effects: Arranging multiple culture panels at intervals within the empty chamber improves the utilization of internal space and provides multi-layered cell culture areas, facilitating diverse cell culture experiments. Furthermore, the sliding connection between the culture panels and the inner wall of the chamber, with the sliding direction aligned with the opening, facilitates easy access to cell culture dishes for operators, improving operational convenience and work efficiency.

[0017] In one optional embodiment, the cell culture apparatus further includes a pair of opposing support columns and multiple pairs of sliding rods located between the pair of support columns, each pair of sliding rods corresponding to a culture panel and located on opposite sides of its corresponding culture panel; the sliding rods are slidably connected to the culture panel.

[0018] Beneficial effects: The support rods and slide bars allow the culture panel to be stably positioned within the chamber, ensuring cell culture dishes are securely placed on the panel and providing a stable culture environment for the cells. Furthermore, the ability of the culture panel to move flexibly on the slide bars allows operators to easily place different cell culture dishes onto their respective panels, improving the convenience of managing and operating various culture dishes.

[0019] In one optional embodiment, the slide bar is provided with a slide rail that faces the same direction as the hatch, and the culture panel is provided with rollers that slide in cooperation with the corresponding slide rail.

[0020] Beneficial effects: Compared to sliding friction, the rolling friction between the roller and the slide is smaller, allowing operators to use less force to change the relative position of the culture panel and the slide bar. This improves operational convenience and reduces the physical exertion required by the operator.

[0021] In one optional embodiment, the support column includes a plurality of sub-support columns, which are spaced apart along the length of the slide rod and connected to the slide rod by fasteners.

[0022] Beneficial effects: The spaced distribution of multiple sub-support columns provides more uniform and stable support for the sliding rod, enhancing the structural stability of the entire cell culture device. This ensures that the culture panel remains stable even during long-term use after bearing cell culture dishes, guaranteeing that the cell culture environment is not disturbed by factors such as device shaking. Secondly, using fasteners to connect the sliding rod and sub-support columns reduces the difficulty of connection operations while ensuring the structural strength of both.

[0023] In one optional embodiment, the side wall of the chamber is further provided with a ventilation hole that communicates with the outside atmosphere and the empty chamber; a monitoring device is provided inside the empty chamber, the monitoring device includes a monitoring probe and a probe support, the monitoring probe is located on the periphery of the culture panel and is mounted on the chamber through the probe support, and the probe support is slidably connected to the chamber.

[0024] Beneficial effects: By incorporating ventilation holes in the chamber, the cells can be provided with the air needed for their growth. Secondly, by installing a monitoring probe on one side of the culture panel, the dynamic changes of the cells under the influence of the magnetic field can be recorded in real time, obtaining accurate experimental data and providing strong data support for subsequent adjustments to the experimental protocol. Furthermore, the sliding connection between the probe support and the chamber allows operators to flexibly adjust the relative position of the monitoring probe and the biological cells, facilitating multi-angle and all-round monitoring of the biological cells.

[0025] In one alternative embodiment, the empty chamber is equipped with a drug stimulation device, which is located above the culture panel and slidably connected to the chamber body.

[0026] Beneficial effects: By setting up a drug stimulation device, operators can observe the effects of drug stimulation on cell function in a non-magnetic environment, which can provide data support and research directions for subsequent studies. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] To address the problem that the poor sealing performance of current magnetic shielding chambers affects the accuracy of data in biological cell research, this invention provides a magnetic shielding chamber.

[0035] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0036] According to embodiments of the present invention, such as Figure 1 As shown, a magnetically shielded cabin is provided, including: cabin body 1 and cabin door 2.

[0037] Specifically, the cabin 1 is provided with an empty cabin 101 and a hatch 102 connected to the empty cabin 101. The hatch 102 is provided with an annular protrusion 103 around the hatch 102. The hatch 2 is provided with an annular groove that cooperates with the annular protrusion 103. The hatch 2 is located in the annular groove through the annular protrusion 103 and fits into the cabin 1.

[0038] This embodiment provides space for storing biological cells by setting an empty compartment 101 inside the chamber 1, meeting the needs of relevant scientific research or experiments for storing biological cells and providing a good foundation for the research and culture of biological cells. Secondly, a hatch 102 connected to the empty compartment 101 is provided on the chamber 1, facilitating the placement and removal of biological cells from the empty compartment 101 by operators, improving operational convenience. Furthermore, the hatch 102 is closed and sealed by the hatch 2, ensuring the airtightness of the empty compartment 101 throughout the entire experimental process.

[0039] It is understood that the empty chamber 101 in this embodiment can provide space for placing biological cells. Therefore, it can also house experimental devices such as cell culture devices 3, so that operators can conduct research and culture of biological cells inside. Furthermore, it should be noted that since the magnetic shielding chamber in this embodiment has the function of shielding external magnetic fields, when the hatch 2 is closed and the hatch opening 102 is sealed, the empty chamber 101 becomes a sealed chamber, thereby preventing external magnetic fields from entering the interior of the magnetic shielding chamber and preventing them from affecting the experimental results inside.

[0040] Furthermore, by setting an annular groove and an annular protrusion 103 between the chamber 1 and the door 2, the door 2 can be correctly aligned with the chamber 1, reducing installation errors and avoiding sealing problems caused by positional misalignment. In addition, compared to simple flat fitting, the annular protrusion 103, inserted into the annular groove, makes the path for external substances, such as moisture, to penetrate the magnetic shielding chamber more complex. This means that the probability of external substances overcoming the combined obstruction formed by the annular protrusion 103 and the annular groove to enter the empty chamber 101 is greatly reduced. In this way, the sealing performance of the magnetic shielding chamber can be improved, ensuring that the internal environment of the magnetic shielding chamber is not disturbed by external substances, providing a stable and reliable environmental guarantee for the smooth conduct of experiments.

[0041] According to one embodiment of the present invention, such as Figure 1 As shown, one of the compartment 1 and the hatch 2 facing each other has a locking part 4, and the other has a locking engagement part 5 that engages with the locking part 4. The locking part 4 or the locking engagement part 5 is located on the outer wall of the compartment 1. In the closed state, the locking part 4 and the locking engagement part 5 are engaged. This engagement enhances the stability of the connection between the compartment 1 and the hatch 2, preventing the hatch 2 from accidentally loosening or opening during use, thus ensuring the safety and reliability of the sealed compartment. Furthermore, it allows the hatch 2 to fit more snugly against the compartment 1 in the closed state, thereby reducing the gap between them and decreasing the possibility of external substances such as moisture entering the sealed compartment.

[0042] Understandably, to ensure the fit between the hatch 2 and the cabin 1 when closed, multiple snap-fit ​​parts 4 or snap-fit ​​mating parts 5 can be provided on the outer side wall of the cabin 1. For example, the top of the cabin 1 is provided with two snap-fit ​​parts 4 spaced apart, and the hatch 2 is provided with two snap-fit ​​mating parts 5 that cooperate with the snap-fit ​​parts 4.

[0043] According to one embodiment of this utility model, both the cabin body 1 and the hatch 2 include a stacked shielding layer and a conductive layer; springs are provided on the surfaces of the annular groove and the annular protrusion 103 facing each other. In the closed state, the conductive layer on the cabin body 1 is connected to the conductive layer on the hatch 2 through the springs. In this embodiment, through the stacked shielding and conductive layers, the cabin body 1 and the hatch 2 can block the interference of external magnetic fields on the internal space. Specifically, the shielding layer usually has a high magnetic permeability, which can guide the external magnetic field around the protected area and reduce the impact of the external magnetic field on the internal environment of the magnetic shielding cabin. The conductive layer can isolate high-frequency magnetic fields through electromagnetic induction, thus isolating and weakening external magnetic fields. In addition, the conductive layer on the cabin body 1 is connected to the conductive layer on the hatch 2 through the springs, so that the conductive layer can form a continuous and complete conductive barrier, enhancing the electromagnetic shielding performance of the magnetic shielding cabin at the joint of the cabin body 1 and the hatch 2, and ensuring the integrity of the magnetic shielding.

[0044] It should be noted that the shielding layer in this embodiment is composed of a material with high magnetic permeability and low magnetic flux density, which may be, but is not limited to, permalloy; the conductive layer is composed of an alloy material with good conductivity, which may be, but is not limited to, copper-aluminum alloy.

[0045] In one embodiment, the inner surface of the sidewall of the cabin 1 is a continuous conductive layer, and the surface of the hatch 2 facing the cabin 1 is also a conductive layer. Thus, when the hatch 2 is closed, a sealed cabin is formed between the cabin 1 and the hatch 2. Furthermore, since the conductive layer on the cabin 1 is conductive to the conductive layer on the hatch 2 when the hatch is closed, the sealed cabin ultimately becomes a magnetically shielded cavity with the function of shielding external magnetic fields.

[0046] According to one embodiment of this utility model, there is at least one shielding layer and one conductive layer, which are alternately arranged, and a filling layer is provided between adjacent shielding layers and conductive layers. The filling layer plays a supporting and insulating role. Its presence can ensure that an appropriate distance is maintained between the shielding layer and the conductive layer, avoiding short circuits due to excessive distance between them. At the same time, it can also prevent electrochemical reactions between them under the influence of external moisture, thereby ensuring the stability and safety of the entire magnetic shielding structure.

[0047] Preferably, in this embodiment, the shielding layer has three layers and the conductive layer has two layers. By adopting a "3+2" main structure distribution layer, the influence of magnetic signals on the cabin can be effectively isolated and blocked, and the shielding effect of the cabin 1 can be improved.

[0048] It should be noted that the filling layer in this embodiment is an insulating material.

[0049] According to one embodiment of the present invention, such as Figure 1 and Figure 2As shown, a cell culture device 3 is installed inside the empty chamber 101, and an electromagnetic coil is installed in the side wall of the chamber 1, located around the periphery of the cell culture device 3. Further, in this embodiment, the cell culture device 3 includes multiple culture panels 301 for placing cell culture dishes. These multiple culture panels 301 are arranged within the empty chamber 101 and spaced apart along the height of the chamber 1, and are slidably connected to the inner wall of the chamber 1. The sliding direction of the culture panels 301 is consistent with the orientation of the hatch 102. An electromagnetic coil is installed in the side wall of the chamber 1, located around the periphery of the cell culture device 3. This embodiment arranges multiple culture panels 301 spaced apart within the empty chamber 101, which improves the utilization rate of the internal space of the empty chamber 101 and provides multiple cell culture areas, facilitating diverse cell culture experiments. Furthermore, the slidable connection of the culture panels 301 to the inner wall of the chamber 1, with the sliding direction consistent with the orientation of the hatch 102, facilitates the operator's access to cell culture dishes, improving operational convenience and work efficiency. Furthermore, the electromagnetic coils installed around the cell culture device 3 can generate a uniform magnetic field inside the chamber 1, thus enabling experiments on the effects of magnetic fields on cell function to be conducted inside the magnetically shielded chamber.

[0050] According to one embodiment of the present invention, such as Figure 2 As shown, the cell culture apparatus 3 also includes a pair of opposing support columns 302 and multiple pairs of sliding rods 303 located between the pair of support columns 302. Each pair of sliding rods 303 corresponds to a culture panel 301 and is located on opposite sides of its corresponding culture panel 301; the sliding rods 303 are slidably connected to the culture panel 301. In this embodiment, with the help of the support rods and sliding rods 303, the culture panel 301 can be stably set in the empty chamber 101, so that the cell culture dishes can be placed stably on the culture panel 301, providing a stable culture environment for the cells. In addition, since the culture panel 301 can move flexibly on the sliding rods 303, the operator can easily place different cell culture dishes on the corresponding culture panel 301, improving the convenience of management and operation of different culture dishes.

[0051] According to one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the slide bar 303 has a slide rail aligned with the hatch 102, and the culture panel 301 has a roller 3011 that slides along the corresponding slide rail. Compared to sliding friction, the rolling friction between the roller 3011 and the slide rail is smaller, so the operator can use less force to change the relative position of the culture panel 301 and the slide bar 303. This improves the ease of operation and reduces the physical exertion required by the operator.

[0052] According to one embodiment of the present invention, such as Figure 2As shown, the support column 302 includes multiple sub-support columns 3021, which are spaced apart along the length of the slide bar 303 and connected to the slide bar 303 via fasteners. The spaced distribution of the multiple sub-support columns 3021 provides a more uniform and stable support force to the slide bar 303, enhancing the structural stability of the entire cell culture device 3. This ensures that the culture panel 301 remains stable even during long-term use after bearing cell culture dishes, guaranteeing that the cell culture environment is not disturbed by factors such as device shaking. Furthermore, connecting the slide bar 303 and the sub-support columns 3021 with fasteners reduces the difficulty of connection operations while maintaining the structural strength of both.

[0053] According to one embodiment of the present invention, such as Figure 1 As shown, the side wall of the chamber 1 is also provided with a ventilation hole 104 that communicates with the outside atmosphere and the empty chamber 101. Preferably, the ventilation hole 104 is located at the top of the chamber 1. In this embodiment, by providing the ventilation hole 104 on the chamber 1, the air required for cell growth can be provided.

[0054] It should be noted that, in order to ensure the airtightness of the chamber 101 when the door is closed, the diameter of the vent 104 needs to be made slightly smaller, so as to prevent external magnetic signals or moisture from entering the chamber 101 through the vent 104 and affecting the experimental data.

[0055] According to one embodiment of this utility model, a monitoring device is provided inside the empty chamber 101. The monitoring device includes a monitoring probe and a probe support. The monitoring probe is located on the periphery of the culture panel 301 and is mounted on the chamber body 1 via the probe support. The probe support is slidably connected to the chamber body 1. This embodiment, by setting a monitoring probe on one side of the culture panel 301, can record the dynamic changes of cells under the influence of a magnetic field in real time, obtaining accurate experimental data, thus providing strong data support for subsequent adjustments to the experimental protocol. Furthermore, the slidable connection between the probe support and the chamber body 1 allows the operator to flexibly adjust the relative position of the monitoring probe and the biological cells, thereby facilitating multi-angle, all-round monitoring of the biological cells.

[0056] According to one embodiment of this utility model, a drug stimulation device is provided inside the empty chamber 101. The drug stimulation device is located above the culture panel 301 and is slidably connected to the chamber body 1. This embodiment, by providing a drug stimulation device, allows operators to observe the effects of drug stimulation on cell function in a non-magnetic environment, thereby providing data support and research directions for subsequent studies.

[0057] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
