Description

Technical Field

[0001] This utility model relates to the field of medical image acquisition technology, specifically to a human body fixation structure for medical image acquisition. Background Technology

[0002] Magnetic resonance imaging (MRI) is one of the most advanced medical imaging methods currently available. Due to its advantages such as multiple imaging parameters, fast scanning speed, high tissue resolution, and clearer images, it is widely used in the diagnosis of lesions in solid organs such as the brain, thyroid, liver, gallbladder, spleen, kidney, pancreas, adrenal glands, uterus, ovaries, and prostate, as well as the heart and major blood vessels.

[0003] Currently, the most common human fixation structures used for medical image acquisition on the market are metal frames, which seriously affects the accuracy of MRI results. This fixation method is not only uncomfortable, but also cumbersome for medical staff to operate. Moreover, traditional medical image acquisition fixation structures are not easy to fix according to the patient's body shape, thus resulting in poor practicality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a human body fixation structure for medical image acquisition. This solves the problem mentioned in the background art, where the currently available human body fixation structures for medical image acquisition generally use metal frames for fixation, which seriously affects the accuracy of MRI results. This fixation method is not only uncomfortable but also cumbersome for medical staff to operate. Furthermore, traditional medical image acquisition fixation structures are not convenient for fixing patients according to their body shape, thus resulting in poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a human body fixation structure for medical image acquisition, comprising a bed board, a movable cavity formed within the bed board, a first fixing frame and a second fixing frame disposed within the movable cavity, sliding grooves formed opposite to each other on the bed board, both ends of the first fixing frame and the second fixing frame disposed within the sliding grooves, a pillow disposed on the bed board, first mounting blocks fixedly installed at both ends of the first fixing frame, first threaded rods rotatably mounted within each first mounting block, a first knob fixedly mounted on the outer end surface of the first threaded rod, a fixing block rotatably mounted on the inner end of the first threaded rod, two stabilizing rods fixedly mounted within the fixing block, both stabilizing rods penetrating to the first mounting block, a first soft pad fixedly mounted within the inner end of each fixing block, a first slot formed at the upper end of the fixing block, and a first positioning hole formed on the fixing block.

[0006] Using the above technical solution, rotating the first knob causes the first threaded rod to rotate, which in turn causes the first threaded rod to move the fixing block inward. The fixing block is rotatably mounted on the threaded rod, and a stabilizing rod is installed on the fixing block, with the stabilizing rod penetrating through the first mounting block. Therefore, the fixing block can remain stable during movement, allowing for better fixation of the patient's foot according to the patient's needs. Medical staff then place the patient's foot on the first strap and pass the first strap through the first slot on the fixing block. After the first strap secures the patient's foot, the medical staff rotates the second knob on the positioning structure, causing the second threaded rod to rotate. This causes the connecting plate to drive the insertion rod through the first adjustment hole on the first strap, and the insertion rod is then inserted into the first positioning hole, thus restricting the first strap and effectively restraining the patient's foot.

[0007] Preferably, the fixing block has a positioning structure that is rotatably mounted, and a first strap is fixedly mounted on the inner end of the fixing block. The first strap has a plurality of first adjustment holes, and the plurality of first adjustment holes are arranged in a rectangular array on the first strap.

[0008] By adopting the above technical solution, the first adjustment hole on the first strap can effectively adjust the first strap according to the patient's body shape, thereby effectively fixing the patient.

[0009] Preferably, a second mounting block is fixedly installed at both ends of the second mounting bracket. A second slot is opened on the second mounting block. A second positioning hole is opened on the second mounting block. A second soft pad is fixedly installed at the inner end of the second mounting block. A second strap is fixedly installed on the second mounting block. A plurality of second adjustment holes are opened on the second strap. The plurality of second adjustment holes are arranged in a linear array on the second strap.

[0010] Using the above technical solution, the patient's wrist is placed on the second strap, and then the second strap is passed through the second slot opened on the second mounting block. After the second strap has secured the patient's wrist, the medical staff rotates the second knob on the positioning structure, thereby causing the second threaded rod to rotate. This causes the connecting plate to drive the insertion rod through the second adjustment hole on the second strap, and then the insertion rod is inserted into the second positioning hole, thereby restricting the second strap.

[0011] Preferably, a first adjusting rod is rotatably mounted inside the first fixing frame, a first limiting block is fixedly mounted at the inner end of the first adjusting rod, and a first handle is fixedly mounted at the outer end of the first adjusting rod. A second adjusting rod is rotatably mounted inside the second mounting frame, a second limiting block is fixedly mounted at the inner end of the second adjusting rod, and a second handle is fixedly mounted at the outer end of the second adjusting rod.

[0012] By adopting the above technical solution, rotating the first handle or the second handle causes the first adjusting rod or the second adjusting rod to rotate, thereby driving the first fixing frame and the second fixing frame to move within the moving cavity. This allows for better movement of the structures on the first fixing frame and the second fixing frame according to the patient's body shape, thus effectively fixing the patient. Furthermore, the ends of the first adjusting rod and the second adjusting rod are respectively equipped with a first limiting block and a second limiting block, which effectively restricts the first fixing frame and the second fixing frame.

[0013] Preferably, the positioning structure includes a second threaded rod, a second knob is fixedly installed at the top of the second threaded rod, a connecting plate is fixedly installed at the bottom of the second threaded rod, and an insert rod is fixedly installed at the bottom of the connecting plate.

[0014] By adopting the above technical solution, the second threaded rod can be rotated by rotating the second knob installed in the positioning structure, thereby allowing the insert rod installed on the bottom connecting plate of the second threaded rod to restrict the first and second straps.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This medical imaging-based human fixation structure involves placing the patient's feet and wrists onto a first strap and a second strap, respectively. The first and second straps are then passed through a first slot and a second slot. Once the patient's feet and hands are secured, medical personnel rotate a second knob to rotate a second threaded rod. This causes a connecting plate to drive an insert rod through the first and second straps. The insert rod then inserts into the first and second positioning holes, thus restricting the first and second straps. This effectively restrains the patient's feet and hands and is relatively simple to operate, allowing medical personnel to quickly fix the patient.

[0017] 2. The human fixation structure for medical image acquisition rotates the first or second handle to rotate the first or second adjusting rod, thereby moving the first and second fixation frames within the moving cavity. This allows for better adjustment of the structures on the first and second fixation frames according to the patient's body shape, thus effectively fixing the patient. The ends of the first and second adjusting rods are respectively equipped with first and second limiting blocks, which effectively restrict the first and second fixation frames. The pillow placed on the bed further enhances the patient's comfort. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Referring to Figures 1-6, a human body fixation structure for medical image acquisition is described. First mounting blocks 5 are fixedly installed at both ends of the first fixation frame 3. First threaded rods 6 are rotatably installed within each first mounting block 5. A first knob 7 is fixedly installed on the outer surface of each threaded rod 6. A fixing block 8 is rotatably installed at the inner end of each threaded rod 6. Two stabilizing rods 9 are fixedly installed within the fixing block 8, both of which penetrate into the first mounting block 5. A first soft pad 10 is fixedly installed at the inner end of the fixing block 8. A first slot 11 is formed at the upper end of the fixing block 8. A first positioning hole 12 is formed on the fixing block 8. A positioning structure 13 is rotatably installed on the fixing block 8. A first strap 14 is fixedly installed at the inner end of the fixing block 8. Multiple first adjustment holes 15 are formed on the first strap 14. The first adjustment holes 15 are arranged in a rectangular array on the first strap 14. The second mounting blocks 16 are fixedly installed at both ends of the second fixing bracket 4. The second mounting blocks 16 have second slots 17 and second positioning holes 18. The inner end of the second mounting blocks 16 is fixedly installed with a second soft pad 19. The second strap 20 is fixedly installed on the second mounting blocks 16. The second strap 20 has multiple second adjustment holes 21 arranged in a linear array on the second strap 20. The positioning structure 13 has a second threaded rod 28. The top end of the second threaded rod 28 is fixedly installed with a second knob 29. The bottom of the second threaded rod 28 is fixedly installed with a connecting plate 30. The bottom of the connecting plate 30 is fixedly installed with a plug rod 31.

[0028] Working principle: When it is necessary to fix the patient's foot, the staff can rotate the first knob 7 to rotate the first threaded rod 6, which in turn moves the fixing block 8 inward. The fixing block 8 is rotatably mounted on the threaded rod, and the stabilizing rod 9 is installed on the fixing block 8 and passes through the first mounting block 5. Therefore, the fixing block 8 can remain stable during movement, which can better fix the patient's foot according to the patient's needs. Then, the medical staff places the patient's foot on the first strap 14 and passes the first strap 14 through the first slot 11 opened on the fixing block 8. After the first strap 14 has secured the patient's foot, the medical staff rotates the second knob 29 on the positioning structure 13 to rotate the second threaded rod 28, which causes the connecting plate 30 to drive the insertion rod 31 through the first adjustment hole 15 on the first strap 14. Then, the insertion rod 31 will be inserted into the first positioning hole 12, thereby fixing the first strap 14. The first restraint effectively restricts the patient's feet. To secure the patient's hands, the wrist is placed on the second strap 20, which is then passed through the second slot 17 on the second mounting block 16. Once the second strap 20 secures the wrist, the medical staff rotates the second knob 29 on the positioning structure 13, causing the second threaded rod 28 to rotate. This causes the connecting plate 30 to drive the insertion rod 31 through the second adjustment hole 21 on the second strap 20. The insertion rod 31 then inserts into the second positioning hole 18, further securing the second strap 20. The inner ends of the fixing block 8 and the second mounting block 16 are respectively equipped with a first soft pad 10 and a second soft pad 19, thus improving patient comfort after restraint. The positioning structure 13 simplifies the process of securing the patient and allows for quicker release of the restraints.

[0029] Example 2:

[0030] Referring to Figures 1-6, a human body fixation structure for medical image acquisition is described. A movable cavity 2 is formed within the bed board 1. A first fixing frame 3 and a second fixing frame 4 are disposed within the movable cavity 2. Opposite sliding grooves 33 are formed on the bed board 1. Both ends of the first fixing frame 3 and the second fixing frame 4 are disposed within the sliding grooves 33. A pillow 32 is disposed on the bed board 1. A first adjusting rod 22 is rotatably mounted within the first fixing frame 3. A first limiting block 23 is fixedly mounted at the inner end of the first adjusting rod 22, and a first handle 24 is fixedly mounted at the outer end of the first adjusting rod 22. A second adjusting rod 25 is rotatably mounted within the second fixing frame. A second limiting block 26 is fixedly mounted at the inner end of the second adjusting rod 25, and a second handle 27 is fixedly mounted at the outer end of the second adjusting rod 25.

[0031] Working principle: Because the bed body has a movable cavity 2, the first fixing frame 3 and the second fixing frame 4 can be moved effectively. When the staff needs to fix people of different heights, they can rotate the first handle 24 or the second handle 27 to rotate the first adjusting rod 22 or the second adjusting rod 25, thereby driving the first fixing frame 3 and the second fixing frame 4 to move within the movable cavity 2. This allows for better adjustment of the structure on the first fixing frame 3 and the second fixing frame 4 according to the patient's body shape, thus effectively fixing the patient. The ends of the first adjusting rod 22 and the second adjusting rod 25 are respectively equipped with a first limiting block 23 and a second limiting block 26, which can effectively restrict the first fixing frame 3 and the second fixing frame 4. The pillow 32 provided on the bed body can improve the patient's comfort.
