Technical Field
[0001] This utility model relates to the field of medical imaging auxiliary equipment technology, and more specifically, to a magnetic resonance imaging lateral support frame. Background Technology
[0002] Magnetic resonance imaging (MRI) is a common imaging technique used in clinical practice. It typically uses the magnetic resonance phenomenon to generate magnetic signals, forming images. This examination is harmless to the human body and involves no radiation, making it suitable for pregnant women.
[0003] During MRI scans, patients are usually examined in different positions, with the lateral position being the most common. However, existing CT scanners can only be used with the patient lying flat, making it difficult to perform lateral examinations on patients who have difficulty moving independently. This is quite inconvenient. Even if some devices can assist patients in turning to the side, they are cumbersome to adjust and inconvenient to operate, which also affects the patient's experience.
[0004] How to invent a magnetic resonance lateral support frame to solve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Example, refer to Figures 1-5A magnetic resonance imaging (MRI) lateral support frame includes a base plate 1, a fixed plate 2, and a flip plate 3. A support column 11 is fixedly connected to the top of the base plate 1, and the top of the support column 11 is fixedly connected to the bottom wall of the fixed plate 2. An installation sleeve 21 is fixedly connected to one end of the fixed plate 2. One end of the flip plate 3 is provided with a connecting rod 31 that matches the installation sleeve 21. The flip plate 3 is rotatably connected to the fixed plate 2 through the cooperation of the connecting rod 31 and the installation sleeve 21, so that the flip plate 3 can be adjusted according to the patient's examination needs. The angle is designed to allow patients to perform MRI examinations in a suitable side-lying position. A positioning cylinder 4 is fixedly connected to the top of the fixing plate 2. A baffle 5 is slidably provided on the upper part of the fixing plate 2. A positioning rod 51 is connected to the side of the baffle 5 facing the positioning cylinder 4. The positioning cylinder 4 has a through groove that matches the positioning rod 51. A hydraulic cylinder 9 is installed at the bottom of the fixing plate 2. A rack 91 is connected to the output end of the hydraulic cylinder 9. A gear 92 is fixedly installed on the connecting rod 31. An installation groove 211 that matches the gear 92 is opened on the installation sleeve 21. The gear 92 meshes with the rack 91. By extending and retracting the hydraulic cylinder 9, the rotation of the gear 92 can be controlled, thereby driving the flip plate 3 to rotate around the connection point with the fixing plate 2, realizing the adjustment of the angle of the flip plate 3 to meet the needs of different examination angles. Moreover, the hydraulic drive can provide stable power to ensure the smoothness of the adjustment process.
[0026] An adjustment groove 60 is provided on one side of the baffle 5 facing the positioning cylinder 4. A positioning element 6 is slidably connected inside the adjustment groove 60. The positioning element 6 and the adjustment groove 60 are connected by a spring 62. Several positioning holes 61 are provided at equal intervals on the fixing plate 2. The positioning holes 61 match the lower end of the positioning element 6. When it is necessary to adjust the position of the baffle 5, the positioning element 6 can be moved. The positioning element 6 can slide in the adjustment groove 60 and stretch the spring 62. Then, it cooperates with the positioning hole 61 in a suitable position to realize the adjustment and fixation of the position of the baffle 5, so as to adapt to the body shape and examination requirements of different patients.
[0027] It should be noted that the lower side wall of the baffle 5 abuts against the top wall of the fixed plate 2 to ensure the stability of the movement of the baffle 5. The upper end of the positioning part 6 extends to the rear side of the baffle 5, which makes it convenient for medical staff to operate the positioning part 6 from the rear side when adjusting the position of the baffle 5, so as to separate or connect it with the positioning hole 61, making the operation more convenient and improving the efficiency of use.
[0028] Reference Figures 1-7A fastening sleeve 82 is installed at one end of the flip plate 3 away from the connecting rod 31. An installation plate 8 is installed on one side of the baffle 5 away from the positioning rod 51. A bandage 81 is connected to the installation plate 8. A fastening bolt 83 is connected to the internal thread of the fastening sleeve 82, which can fasten the bandage 81 in a suitable position to ensure that the patient's body will not slip off the auxiliary frame during the examination, thus playing a safe fixing role. The bandage 81 and the fastening sleeve 82 are set accordingly. Positioning rods 51 are installed on both sides of the baffle 5. Limiting stops 32 are installed on both sides of the flip plate 3. A connecting collar 7 is rotatably connected to the positioning rod 51. One end of the connecting collar 7 away from the positioning rod 51 is sleeved on the outside of the limiting stop 32. Several limiting holes 71 are provided at equal intervals on the connecting collar 7 near the limiting stop 32. Limiting bolts 72 are inserted into the limiting holes 71. The connecting collar 7 on the positioning rods 51 on both sides of the baffle 5 cooperates with the limiting stops 32 on both sides of the flip plate 3. The limiting hole 71 and the limiting bolt 72 on the upper part can limit the relative position between the connecting collar 7 and the limiting stop bar 32. On the one hand, this can further limit the rotation angle of the flip plate 3 to prevent excessive rotation from causing patient discomfort or safety hazards; on the other hand, it can also ensure the relative position between the baffle 5 and the flip plate 3 is stable when the flip plate 3 is at different angles, providing reliable support for the patient.
[0029] It should be noted that the bandage 81 is a telescopic bandage. The telescopic bandage 81 can accommodate the patient's breathing and other minor body movements during the examination process without causing excessive restraint. The gear 92 is located inside the mounting slot 211, which keeps the gear 92 in a relatively enclosed space, preventing personnel from accidentally contacting the gear 92 during operation and causing injury, thus improving the safety and reliability of the auxiliary frame.
[0030] The working principle of this MRI lateral support frame is as follows: First, adjust the flip plate 3 to a horizontal position. The person lies on the flip plate 3, placing one side of their body against the baffle 5. The position of the baffle 5 can be adjusted according to different body types. When the position of the baffle 5 needs adjustment, medical personnel move the positioning component 6 from the back of the baffle 5. The positioning component 6 slides within the adjustment groove 60, simultaneously stretching the spring 62 connected to the adjustment groove 60. When the baffle 5 is slid to the appropriate position, the lower end of the positioning component 6 engages with the corresponding positioning hole 61 on the fixing plate 2, thus fixing the baffle 5 in this position. This adapts to different patient body types and examination requirements.
[0031] After the patient lies on the flip plate 3 and the baffle 5, the bandage 81 on the mounting plate 8 is wrapped around the patient's body and aligned with the fastening sleeve 82 at one end of the flip plate 3. By rotating the fastening bolt 83 inside the fastening sleeve 82, the bandage 81 is fastened in the appropriate position to prevent the patient from slipping during the examination.
[0032] When the hydraulic cylinder 9 at the bottom of the fixed plate 2 is activated, the rack 91 at its output end will move with the extension and retraction of the hydraulic cylinder 9. Since the gear 92 meshes with the rack 91 and the gear 92 is fixedly installed on the connecting rod 31 of the flip plate 3, the linear motion of the rack 91 will drive the gear 92 to rotate in a circle, thereby causing the flip plate 3 to rotate around the mating point of the connecting rod 31 connected to the fixed plate 2 and the mounting sleeve 21, so as to realize the adjustment of the angle of the flip plate 3 to meet the needs of different angles for magnetic resonance examination.
[0033] The connecting collar 7, which is rotatably connected to the positioning rods 51 on both sides of the baffle 5, is sleeved on the outside of the limiting rods 32 on both sides of the flip plate 3. By inserting the limiting bolts 72 into different limiting holes 71 on the side of the connecting collar 7 near the limiting rods 32, the relative position between the connecting collar 7 and the limiting rods 32 is restricted. This can limit the rotation angle of the flip plate 3, avoid excessive rotation that may cause discomfort or safety hazards to the patient, and maintain the relative position stability between the baffle 5 and the flip plate 3 when the flip plate 3 is at different angles, thus providing reliable support for the patient.
[0034] This application uses a hydraulic cylinder 9 to drive a rack 91 and a gear 92 to adjust the angle of the flip plate 3. This achieves precise angle control, meeting the strict requirements of MRI examinations for the patient's lateral posture. Simultaneously, the hydraulic drive provides stable power, ensuring the smoothness of the adjustment process and reducing patient discomfort. The positioning element 6, the adjusting groove 60, the spring 62, and the positioning hole 61 on the fixed plate 2 work together to make the position adjustment of the baffle 5 convenient and flexible. Medical staff can quickly adjust the position of the baffle 5 according to different patient body types and examination needs, improving work efficiency and enhancing the patient's examination experience. The combination of the connecting collar 7, the limiting rod 32, the limiting hole 71, and the limiting bolt 72 not only limits the rotation angle of the flip plate 3, preventing excessive rotation, but also ensures the relative position stability of the baffle 5 and the flip plate 3 at different angles, further improving the safety of the auxiliary frame.
[0035] It should be noted that the specific model and specifications of the hydraulic cylinder 9 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
