Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a scanning bed and imaging diagnostic device. Background Technology

[0002] In imaging diagnostic equipment such as magnetic resonance imaging (MRI) and computed tomography (CT) equipment, the scanning bed can be used to carry the patient and move the patient within the scanning area, thereby enabling whole-body or segmental scanning of the patient to obtain continuous cross-sectional data of the human body, which facilitates diagnosis and treatment by doctors based on the imaging data.

[0003] In existing scanning beds, the control components are typically fixed at the foot of the bed and move synchronously with the bed frame assembly to control its movement and position. Once the imaging diagnostic equipment is powered on, whether in working or standby mode, the electronic components of the control unit are constantly operating and generating heat. This can easily cause the surface temperature of the bed frame assembly to rise (reaching over 30 degrees Celsius). When a patient lies on the bed frame assembly for examination, this increased temperature can lead to discomfort.

[0004] If an insulated mattress is installed on the bed board assembly, although the patient does not directly contact the surface of the bed board assembly, the installation of the insulated mattress will affect the heat dissipation of the bed board assembly and control components. At this time, the surface temperature of the bed board can reach 40-50 degrees Celsius, and the temperature of the control components can reach 70-80 degrees Celsius, which will affect the reliability and service life of the control components.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0047] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0048] To address the technical problems of poor heat dissipation and low comfort in existing scanning beds, this application provides a scanning bed and imaging diagnostic equipment. This scanning bed connects the air-cooled pipe 41 to the accommodating cavity 21 containing the control component 3 via the air inlet 23, enabling forced air cooling of the control component 3. This allows for efficient heat exchange between the control component 3 and the cooling airflow, which ultimately flows out through the heat dissipation section 22 on the accommodating cavity 21. This improves the heat exchange efficiency of the control component 3, thereby enhancing its heat dissipation efficiency and preventing heat buildup that could affect its performance. This helps ensure the reliability and lifespan of both the control component 3 and the scanning bed, while also improving patient comfort while lying on the scanning bed.

[0049] Please see Figures 1 to 12 The first aspect of this application provides a scanning bed, including a base assembly 1, a bed board assembly 2, a control assembly 3, and a cooling assembly 4, such as... Figure 1 , Figure 3 and Figure 4 As shown. The base assembly 1 is used to support the bed board assembly 2 so that the bed board assembly 2 is at a suitable height.

[0050] The bed board assembly 2 is slidably mounted on the base assembly 1 and can be used to move the patient along a specific direction, thereby enabling whole-body or segmental scanning of the patient to obtain imaging data of cross-sections at different locations. One end of the bed board assembly 2 is provided with a receiving cavity 21, and the receiving cavity 21 has a heat dissipation part 22 to allow airflow inside the receiving cavity 21 to escape through the heat dissipation part 22. Figure 4 and Figure 12 As shown (the arrows in the figure indicate the direction of airflow).

[0051] The control component 3 is located inside the accommodating cavity 21 so that the control component 3 can move synchronously with the bed board assembly 2. The accommodating cavity 21 protects the control component 3 while the heat dissipation part 22 dissipates the heat generated by the control component 3, thereby preventing the heat generated by the control component 3 from causing the temperature of the bed board assembly 2 to rise, which helps to improve the comfort of the patient during the examination process.

[0052] The cooling assembly 4 includes an air-cooled pipe 41. An air inlet 23 is provided on the accommodating cavity 21 for communicating with the air-cooled pipe 41. The cooling airflow flows into the interior of the accommodating cavity 21 from the air inlet 23 and exchanges heat with the control assembly 3. The airflow after heat exchange is blown out from the heat dissipation part 22, which can realize forced air cooling of the control assembly 3, which is beneficial to significantly improve the heat dissipation efficiency of the control assembly 3, thereby improving the heat dissipation performance and comfort of the scanning bed.

[0053] It should be noted that, compared to natural heat dissipation solely through the heat sink 22, this application delivers cooling airflow into the accommodating cavity 21 via the air-cooling pipe 41 and the air inlet 23. Guided by the air-cooling pipe 41, the cooling airflow enters the accommodating cavity 21 through the air inlet 23 at a certain pressure and speed, and is finally blown out from the heat sink 22. This forced convection method greatly enhances the gas flow efficiency inside the accommodating cavity 21, enabling the cooling airflow to quickly exchange heat with the heat-generating components inside the cavity, rapidly removing heat.

[0054] At the same time, the efficient gas flow can also promptly discharge the high-temperature gas after heat exchange through the heat dissipation part 22 to the accommodating cavity 21, avoiding the accumulation of heat in the accommodating cavity 21, thereby effectively improving the heat dissipation performance of the entire scanning bed, ensuring that the electronic components in the accommodating cavity 21 can operate stably in a suitable temperature environment, extending the service life of the equipment, and improving the reliability and stability of the system.

[0055] In some embodiments of this application, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The bed board assembly 2 includes a bed board body 24, a receiving cavity 21 located on the lower side of the bed board body 24, and a heat dissipation part 22 located at the end of the bed board body 24. This allows the heat dissipation part 22 to be kept away from the patient's body, preventing hot airflow from blowing onto the patient and ensuring the patient's comfort while lying on the scanning bed is not affected by the hot airflow. Furthermore, the bottom of the bed board body 24 is equipped with a heat insulation component 5 corresponding to the receiving cavity 21, which can block the path of heat generated inside the receiving cavity 21 to the bed board body 24, preventing heat from the control component 3 and the receiving cavity 21 from being conducted upwards or radiated, thereby preventing the temperature of the upper surface of the bed board body 24 (i.e., the surface in contact with the patient) from rising.

[0056] Please refer to some preferred embodiments of this application. Figure 1 and Figure 2 The heat dissipation part 22 is located at the rear end of the bed board body 24 (i.e., the end where the patient's feet are located), has multiple heat dissipation vents and is far away from the patient's body parts, which can prevent hot airflow from blowing on the patient.

[0057] In some embodiments of this application, please refer to Figure 4 and Figure 5 The heat insulation component 5 includes a heat insulation component 51 and a heat insulation component 52 stacked together. The heat insulation component 52 is located on the side of the heat insulation component 51 facing away from the bed board body 24. The heat insulation component 52 can prevent the heat inside the accommodating cavity 21 from being conducted or radiated toward the bed board body 24. The heat insulation component 51 can prevent the heat on the heat insulation component 52 from being conducted or radiated toward the bed board body 24.

[0058] It should be noted that the heat insulation element 52 in the heat insulation assembly 5 plays a crucial initial blocking role. When heat inside the accommodating cavity 21 is conducted or radiated towards the bed board body 24, the heat insulation element 52 forms a heat insulation barrier, significantly reducing the amount of heat transferred. This prevents most of the heat from being transferred to the side of the heat insulation element 52 closest to the accommodating cavity 21, thereby significantly reducing the initial tendency of heat transfer towards the bed board body 24. After prolonged contact with the heat inside the accommodating cavity 21, the temperature of the heat insulation element 52 gradually increases. At this time, the insulation element 51 is tightly fitted to the side of the heat insulation element 52 facing away from the accommodating cavity 21 (i.e., towards the bed board body 24). The material properties of the insulation element 51 further slow down the conduction rate of residual heat on the heat insulation element 52.

[0059] In some embodiments of this application, please refer to Figure 4 and Figure 5 Both the heat insulation component 52 and the heat preservation component 51 are plate-shaped structures, which can cover the top side wall of the accommodating cavity 21 to achieve upper and lower heat separation between the bed board body 24 and the accommodating cavity 21.

[0060] It should be noted that the heat insulation component 52 can be made of a single-layer board, a double-layer board, a vacuum sandwich panel, or a liquid glass heat insulation film, etc., and the heat insulation component 51 can be made of heat insulation cotton, heat insulation pad, etc. As long as the heat in the accommodating cavity 21 is prevented from being conducted upward or radiated to the bed board body 24, the purpose of this application can be achieved.

[0061] In some embodiments of this application, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The bed board body 24 includes a detachable cover plate 241, which is used to open and close the accommodating cavity 21 to facilitate the installation and maintenance of control components inside the accommodating cavity 21.

[0062] Specifically, the cover plate 241 is configured as the upper sidewall of the accommodating cavity 21, and the heat insulation component 5 is disposed on the bottom surface of the cover plate 241 to facilitate the assembly of the heat insulation component 5 and the control component 3 inside the accommodating cavity 21.

[0063] In the above embodiment, since the bed board assembly 2 can slide relative to the base assembly 1, the positions of the accommodating cavity 21 and the air inlet 23 will also change as the bed board assembly 2 slides. Although the connection between the air-cooled pipe 41 and the air inlet 23 can be achieved by a flexible air pipe, the flexible air pipe is prone to wear when the bed board assembly 2 slides back and forth with the air inlet 23, which will affect the reliability of the cooling assembly 4.

[0064] To address the aforementioned issues, please refer to some embodiments of this application. Figure 3 , Figure 4 , Figure 7 , Figure 11 and Figure 12 The bed board assembly 2 and the base assembly 1 have a first sliding position (e.g., Figure 3 (as shown) and the second sliding position (as shown) Figure 11 As shown, the air-cooled duct 41 includes multiple air outlets, which are respectively used to connect with the air inlet 23 in the first sliding position and the second sliding position. By connecting the air outlets in different positions with the air inlet 23 in different sliding positions, it is not necessary to set up a flexible air pipe between the air outlet and the air inlet 23, thereby avoiding wear of the flexible air pipe during the sliding process of the bed board assembly 2.

[0065] In some embodiments of this application, please refer to Figure 3 , Figure 4 , Figure 7 , Figure 11 and Figure 12The air-cooled duct 41 includes a first air outlet 411 and a second air outlet 412. The first air outlet 411 is used to connect with the air inlet 23 in the first sliding position, at which time the cooling airflow pattern is as follows: Figure 4 As shown. The second air outlet 412 is used to communicate with the air inlet 23 in the second sliding position, at which time the flow direction of the cooling airflow is as follows. Figure 12 As shown.

[0066] Specifically, when the bed board assembly 2 is in the first sliding position, the scanning bed is in the initial standby state, and when the bed board assembly 2 is in the second sliding position, the scanning bed is in the sliding scanning state.

[0067] It should be noted that, in addition to the first sliding position and the second sliding position, the bed board assembly 2 and the base assembly 1 may also have other sliding positions to facilitate the acquisition of imaging data of different parts of the patient. The number of air outlets is set in correspondence with the number of sliding positions to ensure the cooling effect of the cooling assembly 4 during the sliding process of the accommodating cavity 21.

[0068] In some embodiments of this application, please refer to Figure 4 , Figure 9 and Figure 12 The air inlet 23 includes multiple air inlets that penetrate the bottom of the accommodating cavity 21. The multiple air inlets are arranged sequentially along the sliding direction of the bed board assembly 2. When the accommodating cavity 21 slides relative to the air outlet with the bed board assembly 2, the input of cooling airflow can be maintained through the multiple air inlets arranged sequentially in the sliding direction.

[0069] During the sliding process of the accommodating cavity 21, the air inlets at different positions will sequentially form good airflow channels with the air outlets of the air-cooled pipe 41. This ensures that the flow rate and velocity of the cooling airflow remain relatively stable throughout the sliding process, providing a uniform cooling effect for the accommodating cavity 21 and the control component 3.

[0070] At the same time, the sequentially arranged air inlets can guide the cooling airflow to form an orderly flow path within the accommodating cavity 21, avoiding the generation of cooling dead zones and further improving heat dissipation performance and cooling reliability.

[0071] In some embodiments of this application, please refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The air-cooled pipeline 41 also includes a multi-port connector 413 and multiple branch pipes. Each branch pipe is provided with an air outlet. The multi-port connector 413 is connected to multiple branch pipes respectively to deliver cooling airflow to multiple branch pipes, so that the cooling airflow is blown out from different air outlets, so as to provide cooling airflow to the accommodating cavity 21 and control component 3 in different sliding positions.

[0072] In some embodiments of this application, please refer to Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 11 and Figure 12 The air-cooled pipeline 41 includes a first branch pipe 414 and a second branch pipe 415 extending toward both ends of the base assembly 1, respectively. The first branch pipe 414 and the second branch pipe 415 are connected by a tee connector (i.e., a Y-shaped pipe connector), which allows the cooling airflow to flow to the first branch pipe 414 and the second branch pipe 415 respectively.

[0073] The first branch pipe 414 has a first air outlet 411 at its end, and the second branch pipe 415 has a second air outlet 412 at its end. When the bed board assembly 2 is located... Figure 3 When in the first sliding position, it connects to the air inlet 23 through the first air outlet 411, and the cooling airflow flows sequentially through the first air outlet 411, the air inlet 23, the accommodating cavity 21, and the heat dissipation part 22, such as Figure 4 As shown, this enables the cooling of control component 3. When the bed plate assembly 2 is located... Figure 11 When in the second sliding position, it connects to the air inlet 23 through the second air outlet 412, and the cooling airflow flows sequentially through the second air outlet 412, the air inlet 23, the accommodating cavity 21, and the heat dissipation part 22, such as Figure 12 As shown, the cooling of control component 3 is achieved.

[0074] In some embodiments of this application, the air-cooled pipeline 41 also includes multiple valves, which are configured one-to-one with multiple branch pipes. This allows the multiple branch pipes to be controlled to switch on and off as the sliding position of the air inlet 23 changes. Only the air outlet corresponding to the position of the air inlet 23 is controlled to supply cooling airflow. This ensures the flow rate of cooling airflow at the air inlet 23 while avoiding waste of cooling airflow, providing a solid foundation for precise control of cooling airflow.

[0075] It should be noted that the position of the air inlet 23 changes continuously as it slides along with the bed plate assembly 2, and the required distribution and intensity of cooling airflow vary at different positions. Through precise control of the valves and branch pipes, the corresponding branch pipes can be dynamically opened or closed based on the real-time sliding position of the air inlet 23. Position sensors connected to multiple valves can be installed on the bed plate assembly 2. When the air inlet 23 slides to a specific working area, the control system can quickly identify that position and control the corresponding valve to open, ensuring that the cooling airflow is only blown out from the corresponding air outlet through the connected branch pipe. This precise on / off control ensures that the cooling airflow acts precisely on the current position of the air inlet 23, achieving a high degree of adaptation between the cooling airflow and the position of the air inlet 23. This avoids blindly delivering cooling airflow, greatly improving the efficiency of cooling airflow utilization and making the cooling effect more significant.

[0076] In some embodiments of this application, please refer to Figure 1 , Figure 3 , Figure 6 , Figure 8 and Figure 11 The base assembly 1 includes a base body 11 and a lifting base 12. The bed board assembly 2 is slidably disposed on the base body 11, allowing the bed board assembly 2 to slide horizontally relative to the base body 11. Figure 1 and Figure 11 As shown. The base body 11 is located on top of the lifting base 12, allowing the lifting base 12 to drive the base body 11 and the bed board assembly 2 to be raised and lowered. The air-cooled pipe 41 is fixed on the base body 11 and can be raised and lowered synchronously with the base body 11.

[0077] The cooling assembly 4 also includes an air supply pipe 42 and a flexible pipe 43. The flexible pipe 43 is connected to both the air supply pipe 42 and the air-cooled pipe 41, allowing cooling airflow to flow sequentially through the air supply pipe 42 and the flexible pipe 43 into the air-cooled pipe 41, thus ensuring the supply of cooling airflow. Furthermore, the flexible pipe 43 can deform as the lifting base 12 rises and falls, preventing the lifting base 12 from affecting the overall performance of the cooling assembly 4 during its lifting and lowering movements.

[0078] It should be noted that the flexible pipe 43 has the characteristic of deforming as the lifting base 12 rises and falls. This avoids problems such as pipe breakage and loosening of connections in the cooling component 4 when the lifting base 12 is adjusted. The application of the flexible pipe 43 completely avoids these problems. When the lifting base 12 rises or falls, the flexible pipe 43 can automatically adjust its length and shape through its own bending, expansion and contraction, maintaining a good connection with the air supply pipe 42 and the air-cooling pipe 41. This adaptive deformation capability allows the cooling component 4 to continuously and stably provide cooling airflow to the equipment without affecting the normal movement of the lifting base 12, greatly improving the structural adaptability and operational flexibility of the equipment.

[0079] In some embodiments of this application, please refer to Figure 3 and Figure 6 The cooling assembly 4 also includes a fan 44. The starting end of the air supply pipe 42 is sealed to the airflow outlet of the fan 44, and the ending end of the air supply pipe 42 is sealed to the bottom end of the flexible pipe 43. The inlet of the multi-port connector 413 of the air-cooled pipe 41 is sealed to the top end of the flexible pipe 43. The flow rate of the cooling airflow can be adjusted by the fan 44, thereby improving the heat dissipation efficiency of the cooling assembly 4. Specifically, for every 1 m / s increase in the flow rate of the cooling airflow, the heat dissipation efficiency can increase by 20-30%.

[0080] In the above embodiments, the flexible pipe 43 can be a plastic canvas spiral pipe, corrugated pipe or other pipe with the ability to expand and contract. As long as it can adapt to the lifting and lowering adjustment of the lifting base 12 through its own bending, expansion and contraction, the purpose of this application can be achieved.

[0081] In some embodiments of this application, please refer to Figure 3 and Figure 4 The cooling assembly 4 also includes a first fixing seat 45 and a second fixing seat 46, wherein the first fixing seat 45 is used to fix the top end of the flexible pipe 43 to the base body 11, and the second fixing seat 46 is used to connect the bottom end of the flexible pipe 43 to the ground.

[0082] As a specific embodiment of this application, please refer to Figure 3 and Figure 4 The flexible pipe 43 is a plastic canvas spiral pipe. The first fixing seat 45 is provided with a first fixing clamp for fixing the top end of the plastic canvas spiral pipe, and the second fixing seat 46 is provided with a second fixing clamp for fixing the bottom end of the plastic canvas spiral pipe. This can be used to reliably fix both ends of the plastic canvas spiral pipe.

[0083] It should be noted that the cooling component 4 can be completely installed inside the base component 1, or components such as the fan 44 can be installed outside the base component 1, depending on the installation environment of the scanning bed.

[0084] Specifically, if the scanning bed is in a low magnetic field environment (e.g., magnetic induction intensity < 1.5T), the fan 44 can be directly installed on the floor at the bottom of the bed. If the scanning bed is greatly affected by the magnetic field (e.g., magnetic induction intensity ≥ 1.5T), the fan 44 can be installed outside the scanning room and connected by a longer air supply pipeline 42.

[0085] Please see Figures 1 to 12 The second aspect of this application provides an imaging diagnostic device, including the scanning bed described in the above embodiments. The scanning bed can move the patient to facilitate scanning the patient's whole body or part of the area, thereby obtaining image data of a specific area.

[0086] It should be noted that the imaging diagnostic equipment can be magnetic resonance imaging (MRI) equipment and computed tomography (CT) equipment, etc. While the scanning bed moves the patient for scanning, the cooling component 4 can achieve efficient heat dissipation of the control component 3 inside the scanning bed, which is beneficial to improving the heat dissipation performance of the scanning bed and the patient's comfort.

[0087] As a specific embodiment of this application, the imaging diagnostic device is a magnetic resonance imaging (MRI) device (i.e., nuclear magnetic scanning device), which works based on the nuclear magnetic resonance (NMR) phenomenon and combined with complex computer image reconstruction technology to achieve imaging of the internal structure of the human body.

[0088] During the MRI scan, the cooling component 4 and the heat dissipation unit 22 can efficiently dissipate heat from the control component 3 inside the scanning bed. At the same time, the heat insulation component 5 installed under the bed board body 24 can prevent heat from being conducted upward or radiated from the cavity 21. This ensures the reliability of the scanning bed while improving the patient's comfort.

[0089] Please see Figures 1 to 12 In some embodiments of this application, the cooling and heat dissipation process of the scanning bed is as follows:

[0090] Step 1: When the scanning bed is in standby mode, the bed plate assembly 2 is located in... Figure 1 and Figure 3 In the first sliding position shown, cooling airflow can be delivered to the first air outlet 411 through the cooling component 4.
