Description

Technical Field

[0001] The present invention relates to the field of magnetic resonance technology, in particular to a baby holder and magnetic resonance equipment. Background Art

[0002] Magnetic resonance imaging (MRI) is the safest clinical imaging method for infants and young children, providing the clearest anatomical contrast. Congenital encephalopathy and acquired factors, such as hypoxic-ischemic encephalopathy (HIE) caused by amniotic fluid aspiration during childbirth, pose significant threats to their physiological and cognitive development. Early diagnosis and intervention are crucial, leading to a high rate of MRI examinations in infants and young children.

[0003] Currently, infants undergoing MRI examinations are typically placed directly on the scanning bed for positioning and fixation, followed by a locator scan. If any deviation in the infant's position is detected, an radiologist must enter the scanning room for a second repositioning. Because infants are much smaller than adults, positioning accuracy is critical. Even a small deviation can cause the imaging anatomical plane to not conform to the uniform standards required for clinical diagnosis. Therefore, the repositioning process sometimes needs to be repeated multiple times, which not only places a significant workload on radiologists but also wastes valuable scanning time and reduces equipment efficiency.

[0004] Therefore, how to improve the efficiency of equipment use is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The core of the present invention is to provide a baby holder that can improve the efficiency of using a magnetic resonance imaging device. Another core of the present invention is to provide a magnetic resonance imaging device including the baby holder, which has a high efficiency.

[0034] In the specific embodiment of the baby support provided by the present invention, please refer to Figures 1 to 9 , including a head support 7, a chest support 20 and an abdominal support 26 arranged in sequence along the longitudinal direction. Among them, a headrest 9 is provided on the head support 7 to improve the patient's comfort during the magnetic resonance examination. Figure 3 As shown, the head support 7, the chest support 20 and the abdominal support 26 are arc-shaped plates, and the center lines of the circles extend longitudinally.

[0035] The infant support further includes a power system. The head support 7, chest support 20, and belly support 26 are all connected to the power system, so that the power system drives the head support 7, chest support 20, and belly support 26 to swing about a center line extending in the longitudinal direction, and drives the head support 7 to move in a transverse direction, the transverse direction being perpendicular to the longitudinal direction. More specifically, the transverse direction and the longitudinal direction are perpendicular to each other and to the vertical direction.

[0036] The infant support also includes a support base 1. Optionally, the support base 1 is in the shape of a rectangular plate. The head support 7, chest support 20, abdominal support 26, and power system are all located above the support base 1. The support base 1 is positioned on a conveyor belt of the magnetic resonance imaging system, with the longitudinal centerline of the support base 1 parallel to the longitudinal centerline of the conveyor belt of the magnetic resonance imaging system. The conveyor belt of the magnetic resonance imaging system is positioned on the magnetic resonance imaging bed 2. By driving the support base 1 to move longitudinally, the various components above the support base 1 can be synchronously moved longitudinally.

[0037] In this embodiment, the power system can automatically adjust the swing of the head support 7, chest support 20 and abdominal support 26, as well as the lateral reciprocating movement of the head support 7, so as to automatically position the baby with the help of the movement of the head support 7, chest support 20 and abdominal support 26, thereby improving the efficiency of equipment use.

[0038] Furthermore, the power system includes a head support drive device and a head support transmission device. The head support transmission device is connected between the head support drive device and the head support 7. In addition, the power system also includes a power box 38, which is fixedly arranged on the support base 1.

[0039] Specifically, the head support transmission device includes a head support swinging part and a head support transverse moving part. The output end of the head support driving device can be switchably connected to one of the head support swinging part and the head support transverse moving part. When the output end of the head support driving device is connected to the head support swinging part, the head support 7 is driven to swing around the center line extending in the longitudinal direction, and the patient's head is swung laterally. When the output end of the head support driving device is connected to the head support transverse moving part, the head support 7 is driven to move back and forth in the transverse direction, and the patient's head is moved laterally. Through the movement of the head support 7, the patient's head can be moved so that the patient's cervical spine is aligned. In this embodiment, by switching the connection between the head support driving device and the head support swinging part and the head support transverse moving part, separate driving in two directions can be achieved, which can reduce the setting of the driving device and help to lighten the equipment.

[0040] Among them, the head support swing component and the head support transverse moving component are both gear structures. A head support gear 31 is fixedly set at the output end of the head support driving device. The head support driving device drives the head support gear 31 to move longitudinally to switch the meshing connection with one of the head support swing component and the head support transverse moving component. The head support driving device drives the head support gear 31 to rotate, so as to drive the head support 7 to swing around the center line extending longitudinally or move laterally with the help of gear transmission. The use of gear transmission can ensure transmission accuracy.

[0041] Specifically, if Figures 6 to 8 As shown, the head support driving device includes a head support rotation driver, a head support driving shaft, a head support switching driver, a force application plate 40 and two relay plates 39 provided on both sides of the force application plate 40 in the longitudinal direction.

[0042] Among them, the head support drive shaft is fixed to the output end of the head support rotation driver, the relay plate 39 is fixedly connected to the head support drive shaft, the force plate 40 is loosely sleeved on the head support drive shaft, and the head support gear 31 is fixed to the head support drive shaft. The head support switching driver drives the force plate 40 to move longitudinally to push the relay plates 39 on both sides to move longitudinally, thereby driving the head support drive shaft to move longitudinally to switch the connection of the head support gear 31 to one of the head support swing component and the head support transverse component. Through the cooperation of the force plate 40 and the relay plate 39, the switching operation can be conveniently realized. Specifically, the longitudinal spacing between the two relay plates 39 is greater than the thickness of the force plate 40.

[0043] Among them, Figure 7 and Figure 8 As shown, the head support drive shaft includes a head support rear drive shaft 37 and a head support front drive shaft 30. The head support rear drive shaft 37 is fixed to the output end of the head support rotation driver. The head support front drive shaft 30 is connected to the head support rear drive shaft 37 through a universal joint mechanism. The relay plate 39 is fixedly connected to the head support rear drive shaft 37, and the force plate 40 is loosely sleeved on the head support rear drive shaft 37. Specifically, the force plate 40 and the relay plate 39 are circular plates, and the inner ring diameter of the force plate 40 is larger than the diameter of the head support rear drive shaft 37. The head support gear 31 is fixed to the head support front drive shaft 30.

[0044] When the head support gear 31 is engaged and connected to the head support transverse moving component, when the head support rotation driver drives the head support rear drive shaft 37 to rotate, the head support front drive shaft 30 is driven to rotate through the transmission of the universal joint mechanism. At the same time, the engagement window hole between the head support transverse moving component and the head support gear 31 causes the head support gear 31 to roll laterally and drive the head support 7 to move laterally.

[0045] Based on the setting of the universal joint mechanism, in this state, the head support rotation driver drives the head support rear drive shaft 37 to rotate, while driving the head support front drive shaft 30 to rotate without interfering with the lateral movement of the head support front drive shaft 30.

[0046] Among them, Figure 5 and Figure 7 As shown, the universal joint mechanism specifically includes a front universal joint 34, a relay shaft 35 and a rear universal joint 36. The two ends of the relay shaft 35 are respectively connected to one end of the front universal joint 34 and one end of the rear universal joint 36, the other end of the front universal joint 34 is connected to the head support front drive shaft 30, and the other end of the rear universal joint 36 is connected to the head support rear drive shaft 37.

[0047] The headrest switching driver includes a headrest switching motor 43, a switching nut 41, a switching screw 42, and a relay rod 60. The headrest switching motor 43 is fixedly mounted in the power box 38, the switching screw 42 is fixedly mounted on the rotating shaft of the headrest switching motor 43, and the switching nut 41 is mounted on the switching screw 42. The switching nut 41 and the switching screw 42 cooperate to drive the switching nut 41 to move back and forth longitudinally. The force plate 40 and the switching nut 41 are fixedly connected by the relay rod 60.

[0048] When the head support switching motor 43 rotates forward, the switching screw 42 drives the switching nut 41 to move toward one end in the longitudinal direction. The switching nut 41 will drive the head support rear drive shaft 37 to move toward one end in the longitudinal direction along with the switching nut 41 through the relay rod 60, the force plate 40 and the relay plate 39, so that the head support gear 31 engages with the head support transverse component to achieve horizontal lateral displacement control of the head support 7. When the head support switching motor 43 rotates backward, the switching screw 42 drives the switching nut 41 to move toward the other end in the longitudinal direction. The switching nut 41 will drive the head support rear drive shaft 37 to move toward the other end in the longitudinal direction along with the switching nut 41 through the relay rod 60, the force plate 40 and the relay plate 39, so that the head support gear 31 disengages from the head support transverse component and then engages with the head support swing component, thereby achieving circumferential swing of the head support 7.

[0049] Among them, a head support transverse sliding rail 3 is fixedly provided on the support seat 1, and the head support slider 4 can be connected to the head support transverse sliding rail 3 in a transverse sliding manner. Specifically, a slide groove is provided at the bottom of the head support slider 4, and the slide groove is slidably buckled on the head support transverse sliding rail 3. The head support transverse moving component is fixed on the support seat 1. Optionally, in the longitudinal direction, two head support transverse sliding rails 3 are provided in sequence, two head support sliders 4 are provided in sequence, and the head support transverse moving component is provided between the two head support transverse sliding rails 3. The head support slider 4 is a rectangular block, and each head support transverse sliding rail 3 is respectively connected with a head support slider 4.

[0050] A head support swing rail 6 is provided on the head support slider 4. The head support 7 is provided on the head support swing rail 6 and can swing on the head support swing rail 6 around a center line extending longitudinally. The head support swing component is fixed to the head support 7. Optionally, the head support swing rail 6 is a slide groove structure, and a head support swing slider 8 is provided on the head support 7 and is slidably connected to the head support swing rail 6. The head support swing rail 6 and the head support swing slider 8 are both arc structures. The center line of the head support 7 and the center line of the head support swing slider 8 coincide with each other. The head support swing slider 8 has the same radius as the head support 7. The output end of the head support drive device is connected to the head support slider 4.

[0051] Based on long-term clinical practice, the lateral movement distance of the headrest slider 4 relative to the longitudinal centerline of the support base 1 is less than 20 mm. Based on this displacement limit, the longitudinal resistance of the headrest front drive shaft 30 and the headrest rear drive shaft 37 is very small, and the universal joint mechanism can realize the axial force of the headrest rear drive shaft 37 on the headrest front drive shaft 30.

[0052] At this time, when the head support driving device is connected to the head support transverse movement component and drives it to move transversely, it can also drive the head support slider 4 and the head support 7 to move transversely. When the head support driving device is connected to the head support swinging component, it can drive the head support 7 to swing on the head support slider 4. The transverse movement and swinging adjustment of the head support 7 do not interfere with each other.

[0053] Among them, Figure 5 and Figure 6 As shown, the head support swing component is a head support swing rack 32, and the head support swing rack 32 is fixedly connected to the bottom surface of the head support 7. Specifically, the head support swing rack 32 is arc-shaped. When the head support gear 31 and the head support swing rack 32 are in meshing state, the head support gear 31 rotates, and the head support 7 can be driven to swing on the head support slider 4 through the head support swing rack 32. The head support transverse moving component is a head support transverse moving rack 33. When the head support gear 31 and the head support transverse moving rack 33 are in meshing state, the head support gear 31 rotates, and the head support 7 and the head support slider 4 can be driven to move transversely through the head support transverse moving rack 33. Among them, the longitudinal spacing between the head support transverse moving rack 33 and the head support swing rack 32 is not less than the thickness of the head support gear 31. Through the arrangement of the head support transverse moving rack 33 and the head support swing rack 32, the structure is simple and gear transmission can be conveniently realized.

[0054] Among them, Figure 8 As shown, the head support rotation driver includes a head support rotation motor 44, a first driven wheel 45, and a first driving wheel 46. The head support rotation motor 44 is fixedly mounted in the power box 38. The first driven wheel 45 is fixedly mounted on the rotating shaft of the head motor 44. The first driving wheel 46 is a long-toothed gear. The axial direction of the first driving wheel 46 is consistent with the longitudinal direction. The tooth width length of the first driving wheel 46 is not less than the longitudinal distance between the head support swing rack 32 and the head support transverse rack 33. The head support rear drive shaft 37 passes through the through hole in the power box 38 and extends into the power box 38. The first driving wheel 46 is fixedly mounted on the head support rear drive shaft 37, and the first driving wheel 46 is engaged with the first driven wheel 45. When the head support switching driver drives the head support rear drive shaft 37 to move longitudinally, the first driving wheel 46 slides longitudinally relative to the first driven wheel 45.

[0055] Of course, in other embodiments, the head support transverse rack can also be fixed to the head support 7, and only by rotating the head support gear, the head support transverse rack and the head support 7 can be driven to move transversely. In addition, in other embodiments, the head support 7 can also achieve its transverse movement and swing through a belt drive.

[0056] Further, if Figure 5 As shown, the head support 7 is further hingedly connected to head support fixing members at both ends in the transverse direction, and the two head support fixing members are connected through a fixing plate spacing adjustment assembly.

[0057] The head support fixture includes a fixing plate and a face support. The fixing plate is an arc plate, one side of which is hinged to the side of the head support 7 in the horizontal direction. The face support is arranged on the fixing plate and is a fabric wrapped with rectangular sound insulation cotton.

[0058] The spacing adjustment assembly includes a rotating tube, a rotating shaft, a spacing adjustment nut 16, and a spacing adjustment screw 17. The two head support fixing plates are each connected to a rotating tube, and the two spacing adjustment nuts 16 are respectively embedded in the two rotating tubes via corresponding rotating shafts. The spacing adjustment screw 17 is a double-ended screw, with the threads at both ends rotating in opposite directions. The ends of the spacing adjustment screw 17 are respectively embedded in the two spacing adjustment nuts 16, and the spacing adjustment screw 17 and the spacing adjustment nuts 16 threadedly engage.

[0059] When the spacing adjustment screw 17 rotates forward, the spacing adjustment nut 16 on the left and the spacing adjustment nut 16 on the right are simultaneously moved closer, and then the spacing adjustment nut 16 on the left drives the left head support fixture closer to the left side of the patient's head through the left rotation shaft and the left rotation tube, and the spacing adjustment nut 16 on the right drives the right head support fixture closer to the right side of the patient's head through the right rotation shaft and the right rotation tube until they fit tightly against the patient's head, which can not only help fix the patient's head, but also reduce noise and sound insulation for the patient. When the spacing adjustment screw 17 rotates backward, the left head support fixture and the right head support fixture can be simultaneously separated from the patient's face.

[0060] Furthermore, the power system includes a chest support rotation driver and a chest support drive shaft 47 connected to the output end of the chest support rotation driver.

[0061] A chest support gear 48 is fixedly mounted on the chest support drive shaft 47. A chest support swing rack 49 is fixedly connected to the chest support 20 and meshes with the chest support gear 48. The chest support rotation driver rotates the chest support gear 48, thereby driving the chest support 20 to swing about a longitudinally extending centerline through the gear transmission. Specifically, the chest support swing rack 49 is arc-shaped and fixed to the bottom surface of the chest support 20.

[0062] Among them, Figure 5As shown, a chest support seat 18 is fixedly provided on the support seat 1, a chest support chute 19 is provided on the top of the chest support seat 18, a chest support slider 21 is fixedly provided on the bottom of the chest support 20, and the chest support slider 21 is slidably connected to the chest support chute 19.

The chest support slider 21 is an arc block, and the inner radius of the chest support slider 21 is the same as the outer radius of the chest support 20, and the center line of the chest support slider 21 coincides with the center line of the chest support 20. The chest support 20 can slide circumferentially in the chest support chute 19 through the chest support slider 21, thereby causing the chest support 20 to swing back and forth to move the patient's chest and align the patient's lumbar spine.

[0063] The chest support rotation driver includes a chest support motor 50, a second driven wheel 51, and a second driving wheel 52. The chest support motor 50 is fixedly mounted in the power box 38, the second driven wheel 51 is fixedly mounted on the rotating shaft of the chest support motor 50, and the second driving wheel 52 is fixedly mounted on the chest support drive shaft 47. The second driving wheel 52 meshes with the second driven wheel 51. The chest support motor 50 drives the second driven wheel 51, which in turn drives the chest support gear 48 to rotate synchronously through the second driving wheel 52, thereby driving the chest support 20 to swing.

[0064] The power system further includes a belly support rotation driver and a belly support drive shaft 53 connected to the output end of the belly support rotation driver. A belly support gear 54 is fixedly mounted on the belly support drive shaft 53. A belly support swing rack, meshing with the belly support gear 54, is fixedly connected to the belly support 26. The belly support rotation driver rotates the belly support gear 54, thereby causing the belly support 26 to swing about a longitudinally extending centerline via a gear transmission. Specifically, the belly support swing rack is arc-shaped and fixed to the bottom surface of the belly support 26.

[0065] Among them, please refer to Figure 4 and Figure 7 , an abdominal support support seat 24 is fixedly arranged on the support seat 1, an abdominal support chute is arranged on the top of the abdominal support support seat 24, and an abdominal support slider is fixedly arranged on the bottom of the abdominal support 26, and the abdominal support slider is slidably connected to the abdominal support chute. The abdominal support support seat 24 is a rectangular block, and two abdominal support support seats 24 are arranged in sequence along the longitudinal direction, and the two abdominal support support seats 24 are parallel to each other. The abdominal support support seat 24 is an arc block, and the inner radius of the abdominal support support seat 24 is the same as the outer radius of the abdominal support 26, and the center line of the abdominal support support seat 24 coincides with the center line of the abdominal support 26. The abdominal support 26 can slide circumferentially in the abdominal support chute through the abdominal support slider, thereby making the abdominal support 26 swing back and forth to move the patient's abdomen and align the patient's lumbar spine.

[0066] The abdominal support rotation driver includes a abdominal support motor 56, a third driven wheel 57, and a third driving wheel 58. The abdominal support motor 56 is fixedly mounted in the power box 38, and the third driven wheel 57 is fixedly mounted on the rotating shaft of the abdominal support motor 56. The abdominal support drive shaft 53 extends into the power box 38 through a through hole in the power box 38.

The abdominal support motor 56 drives the third driven wheel 57, which in turn drives the abdominal support gear 54 to rotate synchronously through the third driving wheel 58, thereby driving the abdominal support 26 to swing.

[0067] Furthermore, to reduce the space occupied by the equipment, the abdominal support drive shaft 53 and the chest support drive shaft 47 are hollow tubular structures. The head support rear drive shaft 37 is inserted into the chest support drive shaft 47, and the outer diameter of the head support rear drive shaft 37 is smaller than the inner diameter of the chest support drive shaft 47. The chest support drive shaft 47 is inserted into the abdominal support drive shaft 53, and the outer diameter of the chest support drive shaft 47 is smaller than the inner diameter of the abdominal support drive shaft 53. The head support rear drive shaft 37, the chest support drive shaft 47, and the abdominal support drive shaft 53 are able to move relative to each other in the longitudinal direction.

[0068] Specifically, the longitudinal direction is the front-to-back direction, and the head support 7 is in the front and the abdominal support 26 is in the back. The head support front drive shaft 30 is rotatably connected to the two head support sliders 4 through bearings, and at the same time, the head support front drive shaft 30 and the bearings are longitudinally slidably connected together through sliders. The front end of the head support rear drive shaft 37 extends out of the chest support drive shaft 47, and the protruding part is rotatably connected to the front chest support support seat 18 through bearings, and at the same time, the head support rear drive shaft 37 and the bearings are longitudinally slidably connected together through sliders. The front end of the chest support drive shaft 47 extends out of the abdominal support drive shaft 53, and the protruding part is rotatably connected to the rear chest support support seat 18 and the front abdominal support support seat 24 through bearings. The abdominal support drive shaft 53 is rotatably connected to the rear abdominal support support seat 24 through bearings.

[0069] Of course, in other embodiments, the abdominal support and the chest support may also be swung by belt transmission or other means.

[0070] The baby support provided in this embodiment can be used for magnetic resonance imaging (MRI) scanning. In addition to its load-bearing function, it also has automatic positioning and fixing functions. During use, the infant is placed on the baby support, which is then placed on the scanning bed, and then the MRI scan is performed. The head support 7, chest support 20, and abdominal support 26 form a segmented support that can be moved independently, driving different parts of the infant to move or swing, thereby achieving automatic positioning. The automatic positioning has high precision, making positioning more accurate and flexible, and eliminating the need for an imaging technician to enter the scanning room for manual operation. In addition, the baby support has a simple structure and is easy to operate.
