Description

Technical Field

[0001] This utility model relates to the field of medical care products technology, and in particular to an adjustable body position fixation device for MRI prone position examination. Background Technology

[0002] In major hospitals, when performing MRI scans in the radiology department, most MRI examination beds can only meet the needs of patients lying flat. For some special examinations, such as those for breast diseases or tethered spinal cord diseases, patients need to maintain a prone position for a period of time during the examination.

[0003] When patients are examined in a prone position for a period of time, we found that image artifacts caused by respiratory movements can interfere with disease diagnosis and hinder the smooth progress of examination and clinical diagnosis. This is because the prone position compresses the patient's chest and / or abdomen, making it easy for the patient's breathing to lose its normal rhythm. In addition, the prone position can also lead to low breathing comfort due to the pressure of the patient's nose and mouth on the bed surface. In particular, it may pose a risk of suffocation to young children who need sedation.

[0004] In response, the inventor of this patent, combining clinical experience, reflecting on problems encountered in clinical work, reviewing a large amount of scientific research data and literature, and conducting a novelty search, gradually conceived and designed this application to solve the relevant technical problems. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this invention is to provide an adjustable body position fixation device for prone MRI examinations.

[0007] The left slide rail and the right slide rail are arranged parallel to each other in the front-back direction; the left and right ends of the head support and the left and right ends of the multiple limb support strips are correspondingly and can slide back and forth in the left slide rail and the right slide rail, and the head support is located in front of the multiple limb support strips.

[0008] When the multiple limb support strips are slid forward and backward, the multiple limb support strips can be slid apart to create a clearance gap facing the patient's chest and / or abdomen.

[0009] In addition, the adjustable body position fixation device for prone MRI examination according to the above embodiments of the present invention may also have the following additional technical features:

[0010] According to one embodiment of the present invention, the head support includes a headrest and a head pillow;

[0011] The headrest is slidably mounted on the left and right slide rails at its left and right ends; the head pillow is located in the middle of the upper surface of the headrest.

[0012] According to one embodiment of the present invention, the front end of the headrest is cut downwards and backwards to form an inclined slope, and the headrest is detachably fixed to the middle of the upper surface of the headrest plate.

[0013] According to one embodiment of the present invention, the bottom surface of the headrest is provided with a male Velcro strap, and the upper surface of the headrest is provided with a female Velcro strap for attaching the male Velcro strap.

[0014] According to one embodiment of the present invention, a face support groove is provided on the upper surface of the headrest near its rear center, and a ventilation groove communicating with the face support groove is also provided on the upper surface of the headrest.

[0015] According to one embodiment of the present invention, the upper front of the headrest is cut downward to form an upper limb resting recess that extends through its left and right sides, for resting the patient's upper limb when the patient is lying prone.

[0016] According to one embodiment of the present invention, a left sliding cavity is provided inside the left slide rail along the front-to-back direction, and a left sliding groove is provided on the right side of the left slide rail along the front-to-back direction, which communicates with the left sliding cavity and has a vertical dimension smaller than that of the left sliding cavity.

[0017] The left end of the headrest is provided with a left slider A that passes through the left sliding groove and extends into the left sliding cavity, and the left ends of the multiple limb support strips are each provided with a left slider B that passes through the left sliding groove and extends into the left sliding cavity; the left slider A and the multiple left sliders B are all relative to the left sliding cavity and cannot slide away to the right.

[0018] According to one embodiment of the present invention, a right sliding cavity is provided inside the right slide rail along the front-to-back direction, and a right sliding groove is provided on the left side of the right slide rail along the front-to-back direction, which communicates with the right sliding cavity and has a vertical dimension smaller than that of the right sliding cavity.

[0019] The head support plate has a right slider A that passes through the right sliding groove and extends into the right sliding cavity at its right end, and multiple limb support strips have right sliders B that pass through the right sliding groove and extend into the right sliding cavity at their right ends; the right slider A and multiple right sliders B are all unable to slide to the left relative to the right sliding cavity.

[0020] According to one embodiment of the present invention, at least one end of the front end and the rear end of the left slide rail is provided with a left mounting port communicating with the left slide cavity and the left slide groove, and a left opening / closing member is provided at the left mounting port; at least one end of the front end and the rear end of the right slide rail is provided with a right mounting port communicating with the right slide cavity and the right slide groove, and a right opening / closing member is provided at the right mounting port.

[0021] According to one embodiment of the present invention, the left slide rail, right slide rail, head support seat, limb support strip, left slider A, left slider B, right slider A, right slider B, left opening and closing component, and right opening and closing component are all made of non-metallic materials.

[0022] The beneficial effects of this utility model are:

[0023] Firstly, the adjustable body positioning device for prone MRI examination provided in this application, in practical implementation, allows the multiple limb support strips to slide open when slid forward and backward, creating a clearance gap directly facing the patient's chest and / or abdomen. For example, when examining a patient for breast diseases, the multiple limb support strips are slid open at appropriate positions, creating a clearance gap A of suitable size directly facing the patient's chest. In this case, the patient's chest is allowed to naturally droop, preventing it from being lifted and compressed by the multiple limb support strips. This also facilitates the placement of a breast-specific coil within the clearance gap A to assist the MRI examination equipment in examining the patient's breast for breast diseases. For example, when special examinations such as those for tethered spinal cord diseases are required, the multiple limb support strips are slid back and forth at appropriate positions to form a suitable clearance gap B facing the patient's abdomen. At this time, the patient's abdomen is cleared and hangs down naturally, so as not to be lifted and compressed by the multiple limb support strips. The patient's abdomen is left empty, which can minimize the obstruction of breathing movement caused by the upward compression of the multiple limb support strips and thus avoid interference with the acquisition of spinal MRI images. At the same time, it can also improve the comfort of the patient when lying prone for examination. Thus, this application is flexible and adaptable.

[0024] Secondly, when the male and female hook and loop fasteners are attached together, it facilitates the connection and fixation between the headrest and the headrest plate. When the male and female hook and loop fasteners are torn apart, it facilitates the easy disassembly of the headrest, making the headrest easy to assemble and disassemble without effort. When the headrest is removed, it facilitates the cleaning and disinfection of the headrest so that it can be used multiple times.

[0025] Thirdly, when the patient lies prone on this application, their face rests on the face support and is supported by the periphery of the face support. At this time, the patient's mouth and nose are located within the face support without being compressed, which can significantly improve their breathing comfort. Especially for young children who need sedation, when lying prone on this application for MRI examination, it can better avoid the risk of suffocation caused by the mouth and nose being squeezed by the upper surface of the headrest in the prone position. In other words, this application avoids the patient's mouth and nose by providing the face support and providing the ventilation slot to allow the patient's mouth and nose to breathe outside within the face support, which helps the patient breathe normally and smoothly, thus making this application highly safe to use.

[0026] Fourthly, in actual use of this application, when the patient lies prone on this application for magnetic resonance examination, their hands can be placed on the upper limb resting platform in a hugging position. In this way, the comfort of the patient lying prone is optimized, and the patient's hands have a place to be comfortably rested at a height, which shows that this application is well-considered.

[0027] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0053] The adjustable body position fixation device 1000 for MRI prone position examination according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0054] Reference Figures 1 to 5As shown, the adjustable body position fixing device 1000 for MRI prone position examination provided according to the embodiment of the present utility model includes a left slide rail 10, a right slide rail 20, a head support seat 30 and multiple limb support strips 40 arranged in the left and right directions for the patient to lie prone.

[0055] The left slide rail 10 and the right slide rail 20 are arranged parallel to each other in the front-back direction; the left and right ends of the head support 30 and the left and right ends of the multiple limb support strips 40 are respectively slidably locked in the left slide rail 10 and the right slide rail 20, and the head support 30 is located in front of the multiple limb support strips 40.

[0056] When the multiple limb support strips 40 are slid forward and backward, the multiple limb support strips 40 can be slid apart to create a clearance gap facing the patient's chest and / or abdomen.

[0057] Based on the above, it is clear that in specific implementation, this application is mainly used as an adjustable body position fixation device 1000 for MRI prone position examination.

[0058] Specifically, when applying this application, refer to Figure 5 As shown, the entire assembly of this application is placed on the surface of the magnetic resonance examination bed 2000 along the length of the magnetic resonance examination bed 2000 so that it is stacked and fixed together with the surface of the magnetic resonance examination bed 2000. Then, the patient who needs to undergo magnetic resonance examination lies on this application in a prone position, and the front and back positions of the multiple limb support strips 40 are adjusted according to the examination items that the patient needs to undergo.

[0059] When it is necessary to examine a patient for breast diseases, the multiple limb support strips 40 are slid back and forth at appropriate positions to form a clearance gap A50 of appropriate size facing the patient's chest. At this time, the patient's chest will be cleared and allowed to hang down naturally, so as not to be lifted and compressed by the multiple limb support strips 40. It is also convenient to place a breast-specific coil in the clearance gap A50 to assist the magnetic resonance imaging examination equipment in examining the patient's chest for breast diseases.

[0060] For example, when special examinations such as spinal cord tethering diseases are required, the multiple limb support strips 40 are slid back and forth at appropriate positions to form a clearance gap B60 of appropriate size facing the patient's abdomen. At this time, the patient's abdomen will be cleared and allowed to hang down naturally, so that it is not lifted and compressed by the multiple limb support strips 40. The patient's abdomen is left empty, which can minimize the obstruction of breathing movement caused by the upward lifting and compression of the multiple limb support strips 40, thus avoiding interference with the acquisition of spinal MRI images. At the same time, it can also improve the comfort of the patient when lying in the prone position for examination.

[0061] Furthermore, by setting the head support 30, the patient's head can be heightened, making the patient's head comfortable. The head support 30 can also slide back and forth, so that it can be slid back and forth to a suitable position to support the patient's head according to the patient's height. Thus, this application is flexible in use.

[0062] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0063] Furthermore, in specific implementation, in accordance with... Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the head support 30 includes a headrest 301 and a head pillow 302;

[0064] The headrest 301 is slidably mounted on the left slide rail 10 and the right slide rail 20 at its left and right ends respectively; the head pillow 302 is located in the middle of the upper surface of the headrest 301.

[0065] Therefore, by setting the headrest 302, the height of the patient's head can be adjusted, making the patient's head comfortable.

[0066] Furthermore, in specific implementation, we will continue to refer to... Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the front end of the headrest 302 is cut to form an inclined slope 3021, and the headrest 302 is detachably fixed to the middle of the upper end surface of the headrest plate 301.

[0067] In this regard, it is clear that by setting the inclined slope 3021 to achieve a smooth transition in height, it is easy to support the patient's neck, making it less likely for the patient's neck area to experience discomfort. Furthermore, the headrest 302 is detachably fixed to the middle of the upper end surface of the head support plate 301, making it easy to disassemble, clean, and disinfect the headrest 302 so that it can be used multiple times.

[0068] Preferably, in this technical solution, it is still compared with Figure 1 and Figure 2 As shown, according to one embodiment of the present utility model, the bottom surface of the headrest 302 is provided with a male hook and loop fastener 3022, and the middle part of the upper surface of the headrest 301 is provided with a female hook and loop fastener 3011 for attaching the male hook and loop fastener 3022.

[0069] Thus, when the male hook and loop fastener 3022 and the female hook and loop fastener 3011 are attached together, it is easy to connect and fix the headrest 302 and the head support plate 301. When the male hook and loop fastener 3022 and the female hook and loop fastener 3011 are torn apart, it is easy to disassemble the headrest 302, making the headrest 302 easy to assemble and disassemble without effort.

[0070] Furthermore, preferably, in this technical solution, the reference is still made. Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the upper end surface of the headrest 302 is provided with a face support groove 3023 near its rear center, and the upper end surface of the headrest 302 is also provided with a ventilation groove 3024 communicating with the face support groove 3023.

[0071] Therefore, it is clear that when a patient lies prone on this application, their face rests on the face support 3023 and is supported by the upper edge of the face support 3023. At this time, the patient's mouth and nose are located within the face support 3023 without being compressed, which can significantly improve their breathing comfort. Especially for young children who need sedation, when lying prone on this application for MRI examination, it can better avoid the risk of suffocation caused by the mouth and nose being squeezed by the upper surface of the headrest 302 in the prone position. In other words, this application avoids the patient's mouth and nose by opening the face support 3023 and setting the ventilation channel 3024 to allow the patient's mouth and nose to breathe outside within the face support 3023, which helps the patient breathe normally and smoothly, resulting in high safety.

[0072] At the same time, in specific implementation, we will continue to refer to Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the upper front part of the headrest 302 is cut downward to form an upper limb resting recess 3025 that runs through its left and right sides for resting the patient's upper limb when the patient is lying in a prone position.

[0073] Therefore, in actual use of this application, when the patient lies prone on this application for magnetic resonance examination, their hands can be placed on the upper limb resting recess 3025 in a hugging position. In this way, the comfort performance of the patient lying prone is optimized, and the patient's hands have a place to be comfortably rested at a height, which makes this application well-considered.

[0074] Furthermore, in specific implementation, in accordance with... Figure 2 and Figure 3As shown, according to one embodiment of the present utility model, a left sliding cavity 101 is provided inside the left slide rail 10 along the front-back direction, and a left sliding groove 102 is provided on the right side of the left slide rail 10 along the front-back direction, which communicates with the left sliding cavity 101 and has a vertical dimension smaller than the vertical dimension of the left sliding cavity 101.

[0075] The head support plate 301 has a left slider A3012 at its left end, which passes through the left sliding groove 102 and extends into the left sliding cavity 101. The left ends of the multiple limb support strips 40 are each provided with a left slider B401 that passes through the left sliding groove 102 and extends into the left sliding cavity 101. The left slider A3012 and the multiple left sliders B401 are all restricted from sliding to the right relative to the left sliding cavity 101.

[0076] Therefore, it can be clearly understood that in actual use of this application, by setting the left slider A3012, the left end of the head support plate 301 can slide back and forth along the left sliding cavity 101 but cannot slide away to the right relative to the left sliding cavity 101. By setting multiple left sliders B401, the left ends of multiple limb support strips 40 can also slide back and forth along the left sliding cavity 101 but cannot slide away to the right relative to the left sliding cavity 101. In this way, the sliding connection between the left end of the head support plate 301 and the left ends of the multiple limb support strips 40 and the left slide rail 10 is very stable and very reliable.

[0077] Furthermore, in specific implementation, in accordance with... Figure 2 and Figure 4 As shown, according to an embodiment of the present utility model, a right sliding cavity 201 is provided inside the right slide rail 20 along the front-back direction, and a right sliding groove 202 is provided on the left side of the right slide rail 20 along the front-back direction, which communicates with the right sliding cavity 201 and has a vertical dimension smaller than the vertical dimension of the right sliding cavity 201.

[0078] The head support plate 301 has a right slider A3013 at its right end that passes through the right sliding groove 202 and extends into the right sliding cavity 201. The right ends of the multiple limb support strips 40 are each provided with a right slider B402 that passes through the right sliding groove 202 and extends into the right sliding cavity 201. The right slider A3013 and the multiple right sliders B402 are all restricted from sliding to the left relative to the right sliding cavity 201.

[0079] Therefore, it can be clearly understood that in actual use of this application, by setting the right slider A3013, the right end of the head support plate 301 can slide back and forth along the right sliding cavity 201 but cannot slide away to the left relative to the right sliding cavity 201. By setting multiple right sliders B402, the right ends of multiple limb support strips 40 can also slide back and forth along the right sliding cavity 201 but cannot slide away to the left relative to the right sliding cavity 201. In this way, the sliding connection between the right end of the head support plate 301 and the right ends of the multiple limb support strips 40 and the right sliding rail 20 is very stable and very reliable.

[0080] Furthermore, in this technical solution, compared with Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, at least one end of the front end and the rear end of the left slide rail 10 is provided with a left mounting port 103 that connects the left slide cavity 101 and the left slide groove 102, and a left opening / closing member 104 is provided at the left mounting port 103 for opening / closing; at least one end of the front end and the rear end of the right slide rail 20 is provided with a right mounting port 203 that connects the right slide cavity 201 and the right slide groove 202, and a right opening / closing member 204 is provided at the right mounting port 203 for opening / closing.

[0081] Therefore, by opening the left mounting port 103, the left slider A3012 and multiple left sliders B401 can be inserted into the left sliding cavity 101 through the left mounting port 103, so as to achieve quick connection of the left slide rail 10, the head support plate 301 and multiple limb support strips 40.

[0082] Furthermore, by opening the right mounting port 203, the right slider A3013 and multiple right sliders B402 can be inserted into the right sliding cavity 201 through the right mounting port 203, so as to achieve quick connection of the right slide rail 20, the head support plate 301 and multiple limb support strips 40.

[0083] Furthermore, in all the above embodiments, according to one embodiment of the present invention, the left slide rail 10, the right slide rail 20, the head support seat 30, the limb support strip 40, the left slider A3012, the left slider B401, the right slider A3013, the right slider B402, the left opening and closing part 104, and the right opening and closing part 204 are all made of non-metallic materials.

[0084] It should be noted that, in practical implementation, for magnetic resonance imaging (MRI) examinations, there must be no metal parts on the patient's body or on the MRI examination bed 2000 to avoid strong interference with the MRI examination. Therefore, this application ensures that the left slide rail 10, right slide rail 20, head support seat 30, limb support strip 40, left slider A3012, left slider B401, right slider A3013, right slider B402, left opening and closing part 104, and right opening and closing part 204 are all made of non-metallic materials to ensure safe use.

[0085] In the preferred embodiment, the left slide rail 10, right slide rail 20, head support plate 301, limb support strip 40, left slider A3012, left slider B401, right slider A3013, right slider B402, left opening and closing component 104 and right opening and closing component 204 described in this application are all made of hard plastic material, and the head support plate 301 and the multiple limb support strips 40 have a certain thickness so as not to be easily crushed.

[0086] Meanwhile, in the preferred embodiment, the headrest 302 described in this application is made of foam material, so that it has a certain degree of hardness, is lightweight and soft, and is not likely to injure the patient's head and face.

[0087] It should be added that, in specific implementation, according to the adjustable body position fixing device 1000 for MRI prone position examination provided by the present utility model embodiment, the upper end surface of the left slide rail 10 is provided with a length measurement scale A (not shown) for indicating the patient's body length from front to back, and the upper end surface of the right slide rail 20 is provided with a length measurement scale B (not shown) for indicating the patient's body length from front to back.

[0088] Therefore, by comparing the length measurement scale A (not shown) and / or the length measurement scale B (not shown), medical staff can more accurately estimate the patient's length, so as to adjust the front and rear positions of the head support 30 and the multiple limb support strips 40 according to the patient's length and actual needs, making the application more flexible in use.

[0089] It is further necessary to add that, in specific implementation, we should continue to refer to... Figure 3 and Figure 4As shown, according to the embodiment of this utility model, the adjustable body position fixation device 1000 for MRI prone position examination includes a left opening and closing member 104 comprising a left rotating plate 1041 and a left locking bolt 1042 fixed to the lower part of the left rotating plate 1041; a left locking screw hole 105 is provided at the lower part of one end of the left slide rail 10 where the left locking opening 103 is opened, and the left locking bolt 1042 is screwed into the left locking screw hole 105 so that the left rotating plate is tightened and blocked outside the left locking opening 103. When the left locking bolt 1042 is loosened to rotate the left rotating plate 1041, the left locking opening 103 can be opened, thus facilitating the disassembly and assembly of the left end of the head support plate 301 and the left ends of the multiple limb support strips 40 in the left slide cavity 101.

[0090] Furthermore, in specific implementation, according to the adjustable body position fixing device 1000 for MRI prone position examination provided by the embodiment of this utility model, the right opening and closing member 204 includes a right rotating plate 2041 and a right locking bolt 2042 fixed at the lower part of the right rotating plate 2041; the right slide rail 20 has a right locking screw hole 205 at the lower part of one end of the right locking opening 203, and the right locking bolt 2042 is screwed into the right locking screw hole 205 so that the right rotating plate is tightened and blocked outside the right locking opening 203. When the right locking bolt 2042 is loosened to rotate the right rotating plate 2041, the right locking opening 203 can be opened, so that the right end of the head support plate 301 and the right ends of the multiple limb support strips 40 can be disassembled and assembled in the right slide cavity 201.

[0091] Other embodiments, etc., will not be described here.

[0092] In summary, the adjustable body position fixation device 1000 for prone MRI examination provided in this application, when the multiple limb support strips 40 are slid forward and backward, can be slid apart to form a clearance gap facing the patient's chest and / or abdomen. When a breast examination is required, the multiple limb support strips 40 are slid apart at appropriate positions to form a clearance gap A50 of suitable size facing the patient's chest. At this time, the patient's chest is allowed to naturally droop, preventing it from being lifted and compressed by the multiple limb support strips 40, and facilitating the placement of a breast-specific coil within the clearance gap A50 to assist the MRI examination equipment in examining the patient's chest for breast diseases. For example, when special examinations such as those for tethered spinal cord diseases are required, the multiple limb support strips 40 are slid open at appropriate positions to create a suitable clearance gap B60 facing the patient's abdomen. This allows the patient's abdomen to hang naturally, preventing it from being lifted and compressed by the multiple limb support strips 40. This empty abdomen minimizes the risk of respiratory obstruction due to the upward pressure from the multiple limb support strips 40, thus avoiding interference with spinal MRI image acquisition. It also improves the patient's comfort during prone examinations. Therefore, this application is flexible and adaptable in its use.

[0093] Furthermore, when the male hook and loop fastener 3022 is attached to the female hook and loop fastener 3011, it facilitates the connection and fixation between the headrest 302 and the head support plate 301. When the male hook and loop fastener 3022 and the female hook and loop fastener 3011 are torn apart, it facilitates the easy disassembly of the headrest 302, making the headrest 302 easy to assemble and disassemble without effort. When the headrest 302 is removed, it facilitates the cleaning and disinfection of the headrest 302 so that it can be used multiple times.

[0094] Furthermore, when the patient lies prone on this application, their face rests on the face support 3023 and is supported by the upper edge of the face support 3023. At this time, the patient's mouth and nose are located within the face support 3023 without being compressed, which can significantly improve their breathing comfort. Especially for young children who need sedation, when lying prone on this application for MRI examination, it can better avoid the risk of suffocation caused by the mouth and nose being squeezed by the upper surface of the headrest 302 in the prone position. In other words, this application avoids the patient's mouth and nose by opening the face support 3023 and setting the ventilation channel 3024 to allow the patient's mouth and nose to breathe outside within the face support 3023, which helps the patient breathe normally and smoothly, thus making this application highly safe to use.

[0095] Meanwhile, in actual use of this application, when the patient lies prone on this application for magnetic resonance examination, their hands can be placed on the upper limb resting recess 3025 in a hugging position. In this way, the comfort performance of the patient lying prone is optimized, and the patient's hands have a place to be comfortably rested at a height, which makes this application well-considered.

[0096] Furthermore, the adjustable body position fixation device 1000 for MRI prone position examination provided in this application is indeed highly practical and has excellent usage effect, which makes this application bound to have great market promotion value, and this application will inevitably be very popular and will definitely be effectively popularized.
