Description

Technical Field

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

[0002] In medical imaging systems, a hospital bed is a device used to support a patient. By adjusting the height, horizontal position, and tilt angle of the bed, the patient can be accurately positioned so that medical imaging equipment (such as X-ray machines, CT scanners, and magnetic resonance imaging (MRI) devices) can image specific parts of the patient's body.

[0003] Because patients need to lie on the bed for an extended period without moving during the scanning process, they are constantly in close contact with the bed, which can cause them to sweat easily. Furthermore, traditional hospital beds lack ventilation and heat dissipation when in contact with the patient, resulting in poor comfort during the examination. Utility Model Content

[0004] The purpose of this application is to provide a medical bed and an MRI device, which aims to solve the problem of poor comfort caused by the inability to ventilate and dissipate heat when traditional beds are in contact with patients.

[0005] This application provides a medical bed, comprising:

[0006] The support includes a head support area, a torso support area, and a limb support area. The torso support area is provided with multiple ventilation holes, which deliver airflow to the examinee or collect airflow flowing through the examinee.

[0007] A base is connected to the support part, and at least one air duct is provided on the base; wherein one end of the air duct is connected to the ventilation hole;

[0008] A fan is connected to the other end of the air duct.

[0009] In one embodiment, the head support area and / or the torso support area includes a support frame and a woven fabric stretched within the support frame such that the woven fabric can contact a portion of the subject's area.

[0015] In one embodiment, the medical bed further includes:

[0016] A control module is disposed inside the base. The control module is electrically connected to the sensor assembly and the fan to adjust the air volume of the fan according to the temperature information and / or the weight distribution.

[0017] In one embodiment, the base is used to provide lifting support for the support part, and the air duct is a flexible structure that extends and retracts with the lifting of the base.

[0018] This application provides a magnetic resonance imaging (MRI) device, comprising:

[0019] Magnetic resonance scanner, with a surrounding scanning cavity;

[0020] A medical bed includes a support and a base, the base being disposed outside the scanning cavity, the base supporting the support, and the support being movable into the scanning cavity;

[0026] A medical bed includes a support and a base, the base being disposed outside the scanning cavity, the base supporting the support, and the support being movable into the scanning cavity;

[0027] The support includes a torso bearing area, which supports the torso of the examinee;

[0028] An air-cooled structure, either inside or separate from the medical bed, is used to deliver cooling air to the torso support area.

[0029] The beneficial effects of this utility model embodiment compared with the prior art are:

[0030] One end of the air duct connects to a ventilation hole, and the other end connects to a fan. The fan, air duct, and multiple ventilation holes form multiple ventilation links. Multiple ventilation holes are provided in the torso support area. These ventilation holes facilitate the transport or collection of airflow between the air duct and the torso support area, allowing for concentrated ventilation and heat dissipation in areas where heat accumulates. Furthermore, the multiple ventilation holes in the torso support area can deliver airflow to or collect airflow passing through the examinee, releasing heat generated in the examinee's torso and achieving ventilation and heat dissipation between the support and the examinee, thereby improving the examinee's comfort during the examination.

[0042] Please see Figure 1 and Figure 2 This application provides a medical bed 100 suitable for magnetic resonance imaging (MRI) devices. The medical bed 100 includes a support 10, a base 30, and a fan 310.

[0043] The support section 10 includes a head support area, a torso support area 101, and a limb support area. The torso support area 101 is provided with multiple ventilation holes 110. The ventilation holes 110 deliver airflow to the subject or collect airflow flowing through the subject.

[0044] The base 30 is connected to the support 10. At least one air duct 320 is provided on the base 30. One end of the air duct 320 is connected to the ventilation hole 110. The fan 310 is connected to the other end of the air duct 320.

[0045] In this embodiment, the support part 10 is in direct or indirect contact with the examinee, providing supine support. The base 30 is the foundation supporting the entire medical bed 100. The base 30 is the supporting structure of the medical bed 100, bearing the weight of the examinee, the weight of the support part 10, and various additional forces generated during the examination. The base 30 provides a flat and stable support platform for the support part 10. During the medical examination, the support part 10 is positioned on the base 30. When undergoing medical examination, the examinee is located on the support part 10.

[0046] The support section 10 is divided into a head support area, a trunk support area 101, and a limb support area. The head support area can be understood as the region supporting the examinee's head. The trunk support area 101 can be understood as the region supporting the examinee's trunk, such as the back, waist, and buttocks. The limb support area can be understood as the region supporting the examinee's limbs, such as the arms, legs, hands, and feet. When the examinee is positioned on the support section 10, the trunk support area 101 has a large contact area with the examinee, and the examinee has a high density of sweat glands in the trunk area, which leads to heat generation and accumulation in the trunk area.

[0047] One end of the air duct 320 is connected to the ventilation hole 110, and the other end of the air duct 320 is connected to the fan 310. The fan 310, air duct 320, and multiple ventilation holes 110 form multiple ventilation links. The torso support area 101 is provided with multiple ventilation holes 110. Through the multiple ventilation holes 110, airflow between the air duct 320 and the torso support area 101 can be transported or collected, enabling concentrated ventilation and heat dissipation in areas where heat accumulates. Furthermore, through the multiple ventilation holes 110 of the torso support area 101, airflow can be transported to or collected from the examinee, allowing the heat generated in the examinee's torso to be released, achieving ventilation and heat dissipation between the support part 10 and the examinee, thereby improving the examinee's comfort during the examination process.

[0048] Thus, the medical bed 100 provided in this application solves the problem of heat generation under the body during long-term scanning caused by traditional hospital beds, improves the comfort of examinees during the examination process, and enhances the examinees' experience during the testing process.

[0049] In one embodiment, the head support area and / or torso support area 101 includes a support frame and a woven fabric. The woven fabric is stretched within the support frame so that it can contact a portion of the subject's area.

[0050] In this embodiment, the woven fabric is a mesh fabric with a mesh structure formed by a weaving process. The woven fabric has many regular or irregular pores, which makes it breathable, water-permeable and supportive, allowing the parts in contact with the subject to quickly dissipate heat and moisture, thereby improving ventilation and heat dissipation in the head support area and / or torso support area 101.

[0051] The woven fabric is taut within the support frame, providing support for the examinee. The fabric is also elastic and stretchable, allowing it to adapt to the examinee's posture and body movements, providing a better fit and thus enhancing the examinee's experience and comfort during the examination.

[0052] In one embodiment, the plurality of ventilation holes 110 may be evenly arranged on the support portion 10 or may be patterned on the support portion 10.

[0053] In one embodiment, the fan 310 can be installed independently or it can be installed in the base 30.

[0054] In one embodiment, both the fan 310 and the air duct 320 are disposed in the base 30. The fan 310 has a blowing mode and / or a suction mode.

[0055] In this embodiment, the fan 310 can be a centrifugal fan, an axial fan, or a mixed-flow fan, etc. The fan 310 is housed within the base 30, facilitating connection to the multiple ventilation holes 110, simplifying installation, and promoting ventilation between the support 10 and the examinee. Furthermore, the multiple air ducts 320 and the fan 310 are both housed within the base 30, preventing exposure in the examination chamber, simplifying equipment integration and maintenance, saving installation space, and facilitating centralized management. Moreover, housing the fan 310 within the base 30 also reduces noise interference, providing a quiet and comfortable testing environment for the examinee, thus improving their comfort.

[0056] Please see Figure 3 In one embodiment, the support portion 10 includes a bed body, and the medical bed 100 further includes a flexible mattress 120. The flexible mattress 120 is placed on the bed body. The flexible mattress 120 has a first through hole 111 corresponding to the ventilation hole 110.

[0057] In this embodiment, the bed body can be understood as a rigid bed board, providing stable support for the examinee. The bed body evenly distributes the examinee's weight, preventing issues such as bed sagging. A flexible mattress 120 contacts the examinee. During the medical examination, the flexible mattress 120 is placed on the bed body, and the support part 10 is positioned on the base 30. When undergoing the medical examination, the examinee lies flat on the flexible mattress 120. The flexible mattress 120 better conforms to the examinee's body, providing a soft and comfortable experience.

[0058] The first through hole 111 is positioned opposite to the ventilation hole 110. The ventilation hole 110 is connected to one end of the air duct 320. The other end of the air duct 320 is connected to the fan 310. The fan 310, multiple air ducts 320, multiple ventilation holes 110, and multiple first through holes 111 form multiple ventilation links. Ventilation is achieved between the flexible mattress 120, multiple first through holes 111, multiple air ducts 320, and the fan 310 through the multiple ventilation holes 110 on the support part 10. Thus, the fan 310 can provide different levels of airflow through the multiple air ducts 320, multiple ventilation holes 110, and multiple first through holes 111, achieving ventilation and heat dissipation at the contact points between the flexible mattress 120 and the examinee. This solves the problem of overheating under the examinee during prolonged scanning caused by traditional hospital beds, improving the examinee's comfort and experience during the examination.

[0059] In one embodiment, a sensor assembly 20 is disposed in a flexible mattress 120. The sensor assembly 20 includes a pressure sensor array 210. The pressure sensor array 210 is staggered with a plurality of first through-holes 111 for sensing the weight distribution of a subject.

[0060] In this embodiment, the pressure sensor array 210 in the sensor assembly 20 is disposed near the plurality of first through holes 111. The plurality of pressure sensors 211 are arranged in an array in the flexible mattress 120 to form the pressure sensor array 210. The pressure sensor array 210 can be patterned in the flexible mattress 120.

[0061] Based on the interaction of forces during equilibrium, when the subject is on the flexible mattress 120, the subject experiences gravity, which exerts a pressure on the mattress 120 equal to the magnitude of gravity. This gravity is applied to the flexible mattress 120 and detected by the pressure sensor array 210 located on the mattress 120. Because different parts of the human body have different pressure distributions, the pressure sensor array 210 can provide real-time information on the gravity of different parts of the subject on the flexible mattress 120. By collecting gravity data from different parts of the subject's body, the pressure sensor array 210 can sense the subject's weight distribution.

[0062] In one embodiment, the sensor assembly 20 in the flexible mattress 120 is correspondingly disposed within the torso support area 101. The torso support area 101 can be understood as the area where the subject is in close contact with the support 10 and is prone to sweating, requiring ventilation and heat dissipation to maintain comfort. By disposing the sensor assembly 20 within the torso support area 101 of the support 10, ventilation and heat dissipation can be provided for areas where the subject is prone to sweating and requires ventilation, thereby maintaining comfort.

[0063] Please see Figure 4 In one embodiment, the sensor assembly 20 further includes an airflow sensor array 230. A plurality of evenly spaced and parallelly arranged ventilation slots 130 are provided within the flexible mattress 120. Each ventilation slot 130 has an air inlet 131 and an air outlet 132 arranged opposite to each other. The air inlet 131 is connected to a fan 310. Each airflow sensor is disposed at the air outlet 132 to detect airflow information at the air outlet 132 when the subject is positioned on the flexible mattress 120.

[0064] The flexible mattress 120 can be made of a low-density, low-attenuation coefficient, non-magnetic, or weakly magnetic material. In one embodiment, the flexible mattress 120 is made of an airtight plastic material. Multiple ventilation slots 130 are evenly spaced and arranged parallel to each other, enabling a uniform distribution of multiple airflow channels. The multiple ventilation slots 130 are independently arranged and not interconnected. Each ventilation slot 130 has an inlet 131 and an outlet 132 at its two ends. Gas generated by the fan 310 enters the ventilation slot 130 through the inlet 131 and exits through the outlet 132. An airflow sensor is installed at the outlet 132. When the ventilation slot 130 is subjected to pressure, it creates resistance to the airflow passing through it. The longer the length of the ventilation slot 130 subjected to pressure, the more areas create resistance to the airflow, resulting in a weaker airflow detected by the airflow sensor at the outlet 132. The airflow strength detected by the airflow sensor is mapped to the length of the ventilation slot 130 subjected to pressure.

[0065] In one embodiment, the ventilation slot 130 is hollow inside, and its inner wall is uniformly and discretely provided with multiple protrusions. When the ventilation slot 130 is subjected to pressure applied by the subject, it can create resistance to the airflow, which is beneficial for the airflow sensor to detect changes in airflow information.

[0066] In one embodiment, each airflow sensor is disposed at the air outlet 132. Each airflow sensor can be disposed outside the scanning chamber, or in other words, outside the aperture, to avoid interference with the magnetic resonance signal.

[0067] In one embodiment, the control module 40 is connected to the airflow sensor array 230 via a transmission line array 410.

[0068] In one embodiment, the sensor assembly 20 further includes at least one temperature sensor 220. The temperature sensor 220 is disposed on the inner wall of the ventilation hole 110 and is used to detect temperature information at the location of the ventilation hole 110.

[0069] In this embodiment, the temperature sensor 220 is disposed on the inner wall of the first through hole 111, which can detect the temperature information at the location of the first through hole 111 in real time. It can not only reflect the temperature information of the ventilation, but also reflect the temperature information between the subject and the support part 10.

[0070] When the temperature sensor 220 detects a higher temperature at the first through-hole 111, it indicates that the heat between the subject and the flexible mattress 120 has increased, requiring timely ventilation to dissipate heat and ensure stable ventilation temperature. Conversely, when the temperature sensor 220 detects a lower temperature between the subject and the flexible mattress 120, it indicates that the heat at the contact point between the subject and the mattress 120 has decreased, requiring timely ventilation to heat the area and ensure stable ventilation temperature.

[0071] Each temperature sensor 220 is disposed on the inner wall of each first through hole 111, which can more accurately detect the temperature information at the location of the first through hole 111 in real time, and thus more accurately obtain the temperature information between the subject and the flexible mattress 120.

[0072] In one embodiment, the control module 40 is disposed inside the base 30 and is electrically connected to the sensor assembly 20 and the fan 310 to adjust the airflow of the fan 310 according to temperature information and / or weight distribution.

[0073] In this embodiment, the control module 40 is connected to the sensor assembly 20 and can acquire sensing parameters in real time. These sensing parameters characterize the sensing information generated when the subject is positioned on the flexible mattress 120. Based on the sensing parameters, the control module 40 can obtain temperature information and / or weight distribution generated when the subject is on the flexible mattress 120. When the pressure information increases, it indicates a strong interaction force between the subject and the flexible mattress 120, and the subject is heavy; in this case, the control module 40 can adjust the fan 310 to increase ventilation. When the pressure information decreases, it indicates a weak interaction force between the subject and the flexible mattress 120, and the subject is light; in this case, the control module 40 can adjust the fan 310 to decrease ventilation. Furthermore, based on the weight distribution feedback from the pressure sensor array 210, the control module 40 adaptively adjusts the ventilation volume of the fan 310 for ventilation and heat dissipation, improving the subject's comfort during the examination.

[0074] When the temperature reading increases, it indicates that the temperature between the subject and the flexible mattress 120 has risen, and the control module 40 can adjust the fan 310 to increase the ventilation volume or / and raise the ventilation temperature. When the temperature reading decreases, it indicates that the temperature between the subject and the flexible mattress 120 has decreased, and the control module 40 can adjust the fan 310 to decrease the ventilation volume or / or lower the ventilation temperature.

[0075] The control module 40 is connected to at least one temperature sensor 220 and can adjust the ventilation temperature and / or ventilation volume of the fan 310 based on temperature information. The control module 40 adaptively adjusts the ventilation temperature of the fan 310 based on temperature feedback at the location of the first through-hole 111 to ensure temperature stability between the examinee and the support 10, further improving the examinee's comfort during the examination process.

[0076] Thus, the control module 40 is connected to at least one temperature sensor 220, which can adaptively adjust the ventilation temperature of the fan 310 in real time according to the temperature information at the location of the first through hole 111, ensuring the temperature stability between the examinee and the flexible mattress 120, further improving the examinee's comfort during the examination process and enhancing the examinee's experience during the examination.

[0077] The control module 40 is connected to the airflow sensor array 230 and the fan 310. The control module 40 is used to adjust the ventilation volume of the fan 310 according to the airflow information.

[0078] When the subject is positioned on the flexible mattress 120, airflow information detected by multiple airflow sensors is sent to the control module 40. Strong airflow indicates a small resistance area, meaning the ventilation channel 130 experiences low pressure, and consequently, the subject's weight is low. Based on this airflow information, the control module 40 can reduce the ventilation volume of the fan 310. Conversely, weak airflow indicates a large resistance area, meaning the ventilation channel 130 experiences high pressure, and consequently, the subject's weight is high. Based on this airflow information, the control module 40 can increase the ventilation volume of the fan 310. Furthermore, based on the strength of the airflow, the control module 40 can determine the length of the ventilation channel 130 under pressure, thereby reconstructing the subject's lateral width profile and weight distribution to obtain the subject's positional information.

[0079] The control module 40 adaptively adjusts the ventilation volume of the fan 310 based on airflow information fed back from multiple airflow sensors to achieve ventilation and heat dissipation between the flexible mattress 120 and the examinee, thereby improving the examinee's comfort during the examination. Furthermore, the control module 40 can determine the examinee's weight based on the airflow information fed back from multiple airflow sensors, and thus sense the examinee's weight distribution.

[0080] Therefore, by connecting the control module 40 to the sensor assembly 20 and the fan 310 respectively, the ventilation volume of the fan 310 can be adaptively adjusted in real time according to the sensing parameters. The ventilation is then delivered to the subject located on the flexible mattress 120 through the air duct 320, the ventilation hole 110 provided in the torso support area 101, and the first through hole 111 provided in the flexible mattress 120. This achieves ventilation and heat dissipation between the flexible mattress 120 and the subject, as well as between the torso support area 101 of the support part 10 and the subject.

[0081] The control module 40 is housed within the base 30, which avoids electromagnetic interference, reduces electrical safety hazards, and facilitates equipment integration and maintenance. Furthermore, the placement of the control module 40 within the base 30 saves testing space and prevents interference during patient testing. Through electrical connection between the control module 40 and the sensor assembly 20 and the fan 310, the airflow and / or temperature of the fan 310 can be adjusted in real time based on the patient's temperature information and / or weight distribution. This solves the problem of patient overheating during prolonged scanning on traditional hospital beds, improving patient comfort and enhancing the overall experience.

[0082] In one embodiment, the control module 40 may be a microprocessor, a field-programmable gate array, or a digital signal processor, etc.

[0083] Please see Figure 5 In one embodiment, the control module 40 is further configured to determine the subject's position information based on the subject's weight distribution. When the subject is on the flexible mattress 120, the weight distribution detected by the sensor assembly 20 is sent to the control module 40. Based on the weight distribution, the control module 40 can determine the weight distribution applied to the flexible mattress 120 at different locations by the subject, and thus reconstruct the position of each part of the subject's body. Based on the position of each part of the subject's body, the subject's position information can be obtained. Therefore, the control module 40 can determine the subject's position information based on the subject's weight distribution.

[0084] Therefore, during medical imaging examinations, the patient's position can be adjusted based on the patient's posture information located on the flexible mattress 120 to meet the requirements of the examination site, scanning sequence, and other examination needs. When the patient's position matches the required position, the scanning begins for the medical imaging examination. When the patient's position deviates from the required position, the patient's position is adjusted in real-time based on the posture information located on the flexible mattress 120.

[0085] In one embodiment, the control module 40 is also used to identify whether the subject is located on the flexible mattress 120 based on the subject's weight distribution, simplifying the staff's operation process and issuing timely alarms to the technicians, which can effectively avoid the risk of forgetting to release the subject after the scan is completed.

[0086] In one embodiment, a heating element is installed within the air duct 320. Airflow generated by the fan 310 is guided to the heating element through the air duct 320. As air flows through the heating element, it heats the airflow, thereby regulating the ventilation temperature of the fan 310. The heating element can be connected to a control module 40. The control module 40 adjusts the power of the heating element based on temperature information to regulate the ventilation temperature.

[0087] In one embodiment, the base 30 provides lifting support for the support 10, and the air duct 320 is a flexible structure. The air duct 320 extends and retracts along with the lifting of the base 30.

[0088] In this embodiment, the base 30 can be made of stainless steel or high-strength alloy steel, etc. The base 30 can be height-adjusted, for example, by adjusting its height, angle, or tilting, and can be configured according to the actual application scenario. The lifting of the base 30 can also cause the support part 10 to rise or fall, and can also cause the air duct 320 to extend or retract, enabling the medical bed 100 to rise and fall more flexibly, allowing for height adjustment according to the actual application scenario.

[0089] The air duct 320 is a flexible structure and can be made of elastic materials such as polyester fiber and polyester film, possessing excellent extensibility and allowing it to extend and retract along with the lifting and lowering of the base 30. Furthermore, the flexible structure of the air duct 320 allows for bending and adjustment according to the installation space within the base 30, facilitating communication between the fan 310 of the base 30 and the ventilation holes 110 of the support 10. Thus, through the lifting support of the base 30 and the extensibility of the air duct 320, the medical bed 100 can be easily installed and offers flexibility.

[0090] In one embodiment, the base 30 is provided with at least one second through hole 330, and the distance between the fan 310 and the second through hole 330 meets the set threshold, for example, the straight distance between the two is less than 0.5m, so that the fan can form air circulation with the outside when it is running.

[0091] In this embodiment, the second through hole 330 is positioned opposite to the fan 310, and is located directly in front of the fan. This allows the fan 310 to exchange gases with the air outside the base 30, enabling either an intake mode or a blowing mode. Thus, by positioning the fan 310 opposite to the second through hole 330, airflow circulation can be achieved between the air duct 320 within the base 30, the ventilation hole 110 of the support 10, and the first through hole 111 of the flexible mattress 120, thereby achieving either an intake mode or a blowing mode.

[0092] This application provides a magnetic resonance imaging device 200, such as... Figure 1 and Figure 2 As shown. The magnetic resonance imaging (MRI) device 200 includes an MRI scanner, a medical bed 100, and a fan 310. The MRI scanner surrounds and forms a scanning cavity 201. The medical bed 100 includes a support 10 and a base 30. The base 30 is disposed outside the scanning cavity 201. The support 10 is disposed on the base 30. The base 30 supports the support 10. The support 10 can move into the scanning cavity 201.

[0093] The support section 10 includes a torso support area 101. The torso support area 101 is provided with a plurality of ventilation holes 110. The ventilation holes 110 deliver airflow to the back of the examinee or collect airflow flowing through the examinee. A fan 310 is disposed within the base 30 and is connected to the ventilation holes 110.

[0094] In this embodiment, the descriptions of the support 10, base 30, and fan 310 can be found in the descriptions of the aforementioned embodiments. The medical bed 100 moves within the scanning cavity 201 to detect medical images. The magnetic resonance imaging (MRI) device 200 utilizes the magnetic resonance phenomenon of atomic nuclei in a magnetic field to construct tomographic images of different tissues within the patient, offering advantages such as high soft tissue resolution, multi-directional imaging, and no ionizing radiation.

[0095] Through the multiple ventilation holes 110 of the torso support area 101, airflow can be delivered to or collected from the subject, so that the heat generated in the subject's torso can be released when the magnetic resonance imaging equipment 200 is used for testing, thereby achieving ventilation and heat dissipation between the support 10 and the subject, and improving the subject's comfort during the examination process.

[0096] In one embodiment, the support 10 further includes a head support area. The head support area includes a support frame and a woven fabric. The woven fabric is stretched within the support frame so that it can support the subject's head.

[0097] In this embodiment, the relevant descriptions of the supporting frame and the woven fabric can be found in the descriptions in the above embodiments.

[0098] This application provides a magnetic resonance imaging (MRI) device 200, including an MRI scanner, a medical bed 100, and an air-cooling structure. The MRI scanner surrounds and forms a scanning cavity 201. The medical bed 100 includes a support portion 10 and a base 30. The base 30 is disposed outside the scanning cavity 201. The support portion 10 is disposed on the base 30. The base 30 supports the support portion 10. The support portion 10 is movable into the scanning cavity 201. The support portion 10 includes a torso support area 101. The torso support area 101 supports the torso of the patient. The air-cooling structure is disposed within the medical bed 100 or separately disposed from the medical bed 100, and is used to deliver cooling air to the torso support area 101.

[0099] In this embodiment, the descriptions of the support 10, base 30, and torso bearing area 101 can be found in the descriptions of the aforementioned embodiments. The air-cooling structure is separated from the medical bed 100, which can be understood as the air-cooling structure being installed independently. The air-cooling structure can be placed close to the medical bed 100, using forced airflow to remove heat and deliver cooling air to the torso bearing area 101.

[0100] In the air-cooled structure, a fan generates airflow that passes through the torso support area 101, carrying away heat. Due to the continuous renewal of air, the air-cooled structure effectively and continuously removes heat from the torso support area 101. Thus, the air-cooled structure allows heat generated in the subject's torso to be released during MRI examination using the MRI machine 200, achieving ventilation and heat dissipation between the support unit 10 and the subject, thereby improving the subject's comfort during the examination.

[0101] In one embodiment, the air-cooled structure is separated from the medical bed 100. The air-cooled structure can deliver cooling air to the torso support area 101 through a single fan. It has a simple structure, is easy to install and maintain, and is low in cost.

[0102] Please see Figure 6 In one embodiment, the magnetic resonance device 200 further includes a local emission coil 300.

[0103] In this embodiment, the magnetic resonance imaging (MRI) device 200 surrounds and forms an open scanning cavity 201. The patient is located on a medical bed 100. The local emission coil 300 is an important component of the MRI device 200. During MRI detection, the coil, which can emit radio frequency signals to a local area of ​​the patient, can be configured according to the body part being scanned (e.g., head, limbs, spine, breast, etc.) to provide a more targeted radio frequency magnetic field.

[0104] In one embodiment, the local transmitting coil 300 includes a coil unit 400 and a protective layer 500 covering the outside of the coil unit 400. The protective layer 500 has a plurality of third through holes 510. The third through holes 510 are corresponding to the ventilation holes 110 of the medical bed 100.

[0105] In this embodiment, the coil unit 400 is the core component of the local transmission coil 300. It is a coil that can transmit radio frequency signals to a local area of ​​the subject. It can be set according to the body part being scanned (such as the head, limbs, spine, breast, etc.) and can provide a more targeted radio frequency magnetic field.

[0106] The protective layer 500 covers the coil unit 400, providing flexibility and impact resistance to protect it from damage caused by impacts, friction, and compression. Furthermore, the protective layer 500 also reduces radio frequency signal leakage and minimizes the impact of external electromagnetic interference on the coil unit 400.

[0107] When undergoing medical testing, the patient is positioned on the support 10 of the medical bed 100. The local emission coil 300 is placed on the body part of the patient to be examined. The ventilation hole 110 and the third through hole 510 are positioned opposite each other, allowing ventilation between them and forming a ventilation link with the fan 310. This facilitates ventilation and heat dissipation between the local emission coil 300 and the contact area with the patient, solving the problem of overheating during prolonged scanning, improving patient comfort, and enhancing the overall experience.
