DETAILED DESCRIPTION
[0030] The present application will now be further described in detail in conjunction with the drawings.
[0031] Please refer to Figures 1-5 The breast MRI examination support air bag rubber pad provided in the embodiment includes a rubber bottom pad 1, two inspection holes 19 and two grooves 2 are formed on the upper side of the rubber bottom pad 1, two movable seats 3 are slidingly fitted in the two grooves 2, two movable blocks 4 are slidingly fitted on the upper side of the two movable seats 3, a fastening belt 15 is fixedly connected between the two movable blocks 4, and a relative movement assembly 5 is arranged on the upper side of the movable seat 3 and matched with the two movable blocks 4.
[0032] A movable support plate 16 is slidingly fitted on one side of the rubber bottom pad 1, a knob 6 is rotatably connected to one side of the movable support plate 16, the knob 6 is connected with one of the relative movement assemblies 5, a telescopic transmission assembly 7 is rotatably fitted in one side of the rubber bottom pad 1, and the telescopic transmission assembly 7 is located between the two relative movement assemblies 5.
[0033] The relative movement assembly 5 arranged on the movable seat 3 can drive the two movable blocks 4 to slide relatively or towards each other along the length direction of the movable seat 3, so as to adjust the tightness and transverse position of the fastening belt 15. When a patient lies on the rubber bottom pad 1 and places the breast in the breast coil through the inspection hole 19, the movable blocks 4 can be driven to move the fastening belt 15 towards the patient's body by operating the relative movement assembly 5, until the fastening belt 15 lightly adheres to the patient's shoulders or both sides of the thoracic cage, so as to properly fix the patient's upper body, effectively limit the patient's involuntary shaking during the examination, and further ensure the stability during image acquisition, improve the image clarity and the accuracy of the examination results. At the same time, since the tightness of the fastening belt 15 can be accurately adjusted by the relative movement assembly 5, the fixing effect can be achieved without causing excessive restraint to the patient, thereby reducing the patient's sense of oppression.
[0034] As Figures 4-5As shown, the relative movement assembly 5 of the embodiment includes a two-way threaded rod 501 rotatably fitted on the movable seat 3, two threaded blocks 502 slidably fitted on the movable seat 3 and threadedly fitted on the circumferential side of the two-way threaded rod 501, and the two threaded blocks 502 are respectively fixedly connected with the two movable blocks 4; the two ends of the two-way threaded rod 501 are opposite in screw direction, the two-way threaded rod 501 is drivingly fitted with the telescopic transmission assembly 7; the rubber bottom pad 1 is internally provided with a fixed groove 11 in communication with the two grooves 2, the fixed groove 11 is slidably fitted with a supporting block 9, one side of the supporting block 9 is provided with a through hole, and the through hole is provided with a bearing 10; the telescopic transmission assembly 7 includes a first rotating shaft 701 provided on the inner side of the bearing 10, a rectangular channel provided on one side of the first rotating shaft 701, and a second rotating shaft 702 slidably fitted in the rectangular channel, one end of the first rotating shaft 701 and one end of the second rotating shaft 702 are respectively drivingly fitted with one end of the two two-way threaded rods 501, and the second rotating shaft 702 is a rectangular structure and is clamped with the rectangular channel; one end of the two two-way threaded rods 501 is respectively provided with a first bevel gear 13, one end of the first rotating shaft 701 and one end of the second rotating shaft 702 are respectively provided with a second bevel gear 14 meshing with the first bevel gear 13, and one side of one of the first bevel gears 13 is provided with a connecting rod fixedly connected with the knob 6.
[0035] Through the rotation of the knob 6, the connecting rod fixedly connected with the knob 6 and the first bevel gear 13 on the corresponding side can be driven to rotate synchronously, since the first bevel gear 13 is meshed with the second bevel gear 14, the rotating power will be transmitted to the second bevel gear 14, and then the first rotating shaft 701 or the second rotating shaft 702 connected therewith is driven to rotate, taking the two-way threaded rod 501 on the same side of the knob 6 as an example, after the first bevel gear 13 at one end thereof is driven to rotate by the knob 6, the second rotating shaft 702 will be driven to rotate through the meshing second bevel gear 14, and since the second rotating shaft 702 is clamped with the rectangular channel of the first rotating shaft 701 due to the rectangular structure, the rotation can be synchronously transmitted to the first rotating shaft 701, and the first rotating shaft 701 drives the two-way threaded rod 501 on the other side to rotate through the meshing of the second bevel gear 14 at the other end thereof with the first bevel gear 13 at the end of the two-way threaded rod 501 on the other side, so that the two-way threaded rod 501 on the other side is also driven to rotate, when the two two-way threaded rods 501 rotate, since the screw directions of the two ends thereof are opposite and the two threaded blocks 502 are threadedly fitted on the circumferential sides thereof, the two threaded blocks 502 will slide towards or away from each other along the two-way threaded rods 501, the sliding of the threaded blocks 502 directly drives the movable blocks 4 fixedly connected therewith to move synchronously in the grooves 2, the adjustment of the distance between the two movable blocks 4 is realized, at the same time, the sliding fitting of the supporting block 9 in the fixed groove 11 and the supporting effect of the bearing 10 on the first rotating shaft 701 ensure the stability of the telescopic transmission assembly 7 in the process of transmitting power, and the sliding of the second rotating shaft 702 in the rectangular channel provides the possibility for the adaptive change of the distance between the two two-way threaded rods 501, so that the adjustment process of the whole relative movement assembly 5 is more flexible and smooth.
[0036] As shown in Figure 4 The fixed groove 11 is provided with a limiting groove, and a limiting block fixedly connected with the supporting block 9 is slidably matched in the limiting groove.
[0037] The sliding matching of the limiting block and the limiting groove can strictly limit the sliding stroke of the supporting block 9 in the fixed groove 11, effectively prevent the supporting block 9 from disengaging from the fixed groove 11 due to excessive displacement in the sliding process, and further improve the structural stability and operation reliability of the telescopic transmission assembly 7 during power transmission. When the supporting block 9 slides in the fixed groove 11 along with the change of the distance between the two bidirectional threaded rods 501, the limiting block will slide in the limiting groove at the same time, and the inner walls at both ends of the limiting groove will rigidly constrain the movement range of the limiting block, ensuring that the supporting block 9 always moves within the preset safe range, avoiding the risk of failure of the entire transmission system or damage of the components due to the sliding off of the supporting block 9.
[0038] As shown in Figure 1 The rubber bottom pad 1 is provided with an air chamber, a plurality of supporting air bags 17 are arranged on the upper side of the rubber bottom pad 1 and connected with the air chamber, and a gas charging and discharging core 18 is arranged on one side of the rubber bottom pad 1 and connected with the air chamber.
[0039] The end of the gas charging and discharging core 18 is provided with a rotatable sealing cover to prevent gas leakage in the non-use state. The plurality of supporting air bags 17 are arranged in a matrix on the upper side of the rubber bottom pad 1, and the top of each supporting air bag 17 is an arc-shaped convex structure. This structure design can better fit the physiological curve of the breast part of the patient, thereby providing stable support while effectively dispersing local pressure and avoiding the discomfort of the patient caused by traditional hard supports. The edges of the rubber bottom pad 1 are rounded, further improving the comfort of the patient during the examination process and reducing the friction and pressure on the skin.
[0040] As shown in Figure 3As shown, the head support pad 20 of the embodiment has a face placing groove 21 on the upper side. The shape of the face placing groove 21 is matched with the face contour of the human body, and is in an inverted U-shaped structure. The inside of the face placing groove 21 is filled with soft and elastic memory cotton material, which can be self-adapted to the specific shape of the patient's face, thereby providing stable and comfortable support for the patient's head during the examination. The edges of the face placing groove 21 are also rounded to avoid pressing the patient's face skin, effectively improving the comfort of the patient in the long-term head fixation state. In addition, a through breathing hole 22 is provided at the position corresponding to the patient's mouth and nose of the face placing groove 21. The breathing hole 22 not only ensures smooth breathing of the patient, prevents breathing problems caused by long-term prone position, but also reduces the stuffy feeling between the face and the support pad, further improving the overall examination experience of the patient. The bottom of the head support pad 20 is detachably connected with the rubber bottom pad 1 through the magic tape, which facilitates quick replacement and adjustment according to the head size and examination needs of different patients, enhancing the versatility and practicality of the entire support device.
[0041] As shown in the figure, Figure 2 Figure 2 The rubber bottom pad 1 of the embodiment is fixedly connected with two support rods 22 on one side of the head support pad 20, and the ends of the two support rods 22 are fixedly connected with pull rings 23.
[0042] When the patient is undergoing breast MRI examination, the patient can put his hands through the pull rings 23 and hold them. Through the fixed structure of the pull ring 23 and the support rod 22, a stable placement position can be provided for the patient's upper limbs, avoiding the patient's hands from moving unconsciously due to the long examination time and the lack of a place to put them, thereby reducing the artifacts caused by limb movement and ensuring the clarity and accuracy of the MRI image. At the same time, the height and angle of the support rod 22 are carefully designed to meet the ergonomic principle, so that when the patient holds the pull ring 23, the shoulder can be naturally relaxed, reducing the tension of the upper limb muscles and further improving the comfort of the patient during the examination. The fixed connection between the rubber bottom pad 1 and the support rod 22 adopts a combination of high-strength glue bonding and bolt reinforcement, which ensures that the support rod 22 will not shake or displace when the patient exerts force on it, ensuring the stability and reliability of the entire support structure. The inner wall of the pull ring 23 is also wrapped with a 2mm-thick silicone cushion. The soft cushion has a soft texture and a comfortable touch, which can effectively prevent the patient's hands from leaving marks due to hard contact with the pull ring 23. At the same time, the silicone material has good anti-slip performance, which can prevent the patient's hands from slipping due to sweating during the examination, further enhancing the stability of the hand grip.
[0043] Working principle:
[0044] When the patient is subjected to breast MRI examination, first, the rubber bottom pad 1 is placed in the appropriate position of the MRI examination bed, and the inflation amount of the supporting air bag 17 is adjusted by the inflation and deflation core 18 according to the body size of the patient, so that the top arc-shaped protrusion better fits the physiological curve of the chest and abdomen of the patient, then the patient lies down on the rubber bottom pad 1, aligns the breast, and naturally drops into the breast coil through the examination hole 19, the face is placed in the face placing groove 21 of the head supporting pad 20, and the breathing hole 22 is aligned with the mouth and nose to ensure smooth breathing, then the patient's hands pass through the pull ring 23 and naturally hold it, at this time, the shoulder is naturally relaxed under the cooperation of the supporting rod 22 and the pull ring 23, the medical staff rotates the knob 6 on the movable supporting plate 16, the knob 6 drives the first bevel gear 13 at the end of the connecting rod and the double-direction threaded rod 501 on the same side to rotate, and through the meshing with the second bevel gear 14, the power is transmitted to the second rotating shaft 702 and the first rotating shaft 701 in turn, and then the meshing of the second bevel gear 14 and the first bevel gear 13 on the other side drives the double-direction threaded rods 501 on both sides to rotate synchronously, since the threaded directions of the double-direction threaded rods 501 at both ends are opposite, the threaded blocks 502 on the periphery drive the movable blocks 4 and the fastening belts 15 to move relatively, until the fastening belts 15 lightly adhere to the shoulders or both sides of the chest of the patient, and the moderate fixation of the upper body of the patient is realized, and in the whole examination process, the sliding of the limiting block in the limiting groove in the fixed groove 11 ensures that the supporting block 9 stably supports the telescopic transmission assembly 7, and the memory cotton filling of the head supporting pad 20, the round corner processing of the rubber bottom pad 1 and the silica gel soft pad of the pull ring 23 jointly provide a stable and comfortable examination environment for the patient, effectively reduce the non-autonomous shaking, and ensure the clarity of the MRI image acquisition and the accuracy of the examination result.
