Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an arm support device. Background Technology

[0002] Ultrasound examination is a diagnostic method that utilizes the reflection and attenuation patterns of ultrasound waves propagating within the human body. These waves are visualized on an oscilloscope screen, showing the effects of reflection and attenuation by various organs and tissues. Ultrasound waves have excellent directionality; as they propagate within the body, they encounter tissues and organs of different densities, resulting in reflection, refraction, and absorption. Musculoskeletal ultrasound is typically used clinically for targeted examination of muscles, bones, nerves, and joints, employing a specialized frequency probe. Musculoskeletal ultrasound allows for detailed observation of diseases of the musculoskeletal system, such as bone tumor-like lesions, primary bone tumors, or bone metastases.

[0003] Currently, when diseases are detected in patients' muscles, bones, nerves, and joints, musculoskeletal ultrasound-guided drug injection interventional therapy can be performed. During the treatment, the doctor needs to hold the probe to examine the patient. During the examination, the ultrasound doctor needs to slowly examine the patient's area for a long time to find the damaged location, which means that the doctor's arm will be suspended in the air for a long time. The long suspension time can easily cause shoulder pain and probe instability for the ultrasound doctor, thus increasing the difficulty of the operation of the treatment process. Utility Model Content

[0004] The purpose of this invention is to solve the problem mentioned in the background art above, which requires long and slow scanning of the patient's area to find the damaged location, causing the doctor's arm to be suspended in the air for a long time. The excessive suspension time can easily lead to shoulder pain and probe instability for the ultrasound doctor, thus increasing the difficulty of the operation during the treatment process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An arm support device includes a clamping mechanism, wherein the clamping mechanism is provided with an adjustment mechanism capable of height adjustment, and the adjustment mechanism is provided with a support mechanism capable of supporting the arm.

Example

[0031] Please refer to Figure 1-6 An arm support device includes a clamping mechanism 1, an adjustment mechanism 2 capable of height adjustment on the clamping mechanism 1, and a support mechanism 4 capable of supporting the arm on the adjustment mechanism 2.

[0032] The support mechanism 4 includes a support plate 41 and a hinge plate 43. A hinge block 42 is provided in the middle of the lower surface of the support plate 41. The hinge block 42 is hinged to the hinge plate 43 by a positioning pin. A limiting block 44 is provided on the side of the hinge plate 43 to limit the rotation of the hinge block 42.

[0033] Two limiting blocks 44 are symmetrically arranged to limit the rotation and tilt angle of the tray 41. The tray 41 can rotate and tilt slightly, which improves the comfort of the doctor when placing the arm for operation.

[0034] The clamping mechanism 1 is provided with a storage slot. When folded, the adjustment mechanism 2 can fit perfectly into the storage slot. The storage slot is located on the right side of the lower clamping plate 12 and the upper clamping plate 11. The adjustment mechanism 2 can be folded into the storage slot for easy carrying by doctors.

[0035] The clamping mechanism 1 includes an upper clamping plate 11 and a rotating ring 18. A lower clamping plate 12 is provided below the upper clamping plate 11. A bolt 16 is provided on the upper clamping plate 11. A connecting end 19 protrudes from the upper surface of the rotating ring 18. A connecting hole 17 is provided on the lower clamping plate 12. The connecting end 19 on the rotating ring 18 is rotatably disposed in the connecting hole 17 of the lower clamping plate 12. A nut is provided in the connecting end 19. The bolt 16 is connected to the nut and passes through the rotating ring 18. A rotating rod 110 is provided on the outer surface of the rotating ring 18. The doctor can apply force to rotate the rotating ring 18 better by rotating the rotating rod 110.

[0036] A limiting rod 15 is provided below the upper clamping plate 11. The limiting rod 15 passes through the lower clamping plate 12. Both the upper clamping plate 11 and the lower clamping plate 12 have protruding protrusions 14 on their left ends. The limiting rod 15 is connected to the lower part of the protrusion 14 on the upper clamping plate 11. A limiting hole is provided on the protrusion 14 on the left end of the lower clamping plate 12. The upper clamping plate 11 and the lower clamping plate 12 are parallel, and the limiting rod 15 is located in the limiting hole. The limiting rod 15 can limit the lower clamping plate 12, so that the lower clamping plate 12 is always parallel to the upper clamping plate 11.

[0037] The adjusting mechanism 2 includes an outer rod body 21 and a rotating ring 2. A connecting end 2 protrudes from the lower surface of the rotating ring 2, and a nut 27 is provided inside the connecting end 2. A threaded rod 23 is provided inside the nut 27. The outer rod body 21 has a cavity inside. The connecting end 2 on the rotating ring 2 is rotatably set inside the upper end of the outer rod body 21. The threaded rod 23 is located inside the cavity of the outer rod body 21. Through the threaded engagement between the threaded rod 23 and the nut 27, the threaded rod 23 can move up and down when the nut 27 is rotated, thereby driving the support plate 41 to move and adjusting the height of the support plate 41.

[0038] The outer rod body 21 has a limiting rod 25 inside its cavity, and the lower end of the threaded rod 23 has a limiting plate 24. The limiting rod 25 passes through the limiting plate 24, and the limiting plate 24 has a limiting hole 2. The limiting rod 25 is located in the limiting hole 2. The threaded rod 23 can be limited by the limiting plate 24 and the limiting rod 25, so that the threaded rod 23 will not rotate when the nut 27 is rotated, so that the threaded rod 23 can move up and down linearly.

[0039] A rotating pin 22 is provided at the lower end of the outer surface of the outer rod 21, and a rotating end 13 protrudes from the upper surface of the upper clamping plate 11. The two rotating pins 22 are respectively rotatably located in the two rotating ends 13. The outer rod 21 can rotate through the rotating pins 22, and the outer rod 21 can be rotated and folded when carried, so as to facilitate the doctor's carrying.

[0040] Two insertion holes are provided on the outer surfaces of the two rotating pins 22, and two insertion holes are provided on the outer surfaces of the two rotating ends 13. The two rotating pins 22 are respectively set in the two rotating ends 13 by two pins 3. The positions of the two rotating ends 13 can be fixed by the two pins 3 respectively. The pins 3 can be inserted into the corresponding insertion holes of the two insertion holes on the rotating pins 22 to fix the rotating pins 22 and prevent the outer rod 21 from rotating.

[0041] The upper surface of the support plate 41 is provided with a rubber layer, and multiple anti-slip strips are provided at equal intervals on the right side of the inner surface of the upper clamp 11 and the lower clamp 12. The rubber layer improves the comfort of the doctor when placing the arm, and the anti-slip strips can increase the friction between the upper clamp 11 and the lower clamp 12 and the bed board, thereby improving the stability of the clamping.

[0042] In use, the bed board is positioned between the upper clamping plate 11 and the lower clamping plate 12, with the lower surface of the upper clamping plate 11 in contact with the bed board. Then, the rotating rod 110 is rotated, causing the rotating plate to rotate, which in turn causes the nut to rotate. The rotating nut moves towards the bed board, which in turn moves the lower clamping plate 12, causing it to contact the bottom of the bed board. This allows the upper clamping plate 11 and the lower clamping plate 12 to clamp the bed board, thus fixing the support bracket to the bed board. This allows the doctor to place their arm on the support plate 41 during musculoskeletal ultrasound treatment, supporting the arm and preventing fatigue from prolonged periods of maintaining one posture. The support plate 41 also allows for angled rotation through the hinge between the hinge block 42 and the hinge plate 43, ensuring that the doctor's arm has some range of motion while supporting it, thus improving comfort during support.

[0043] Rotating the rotating plate 26 causes the nut 27 to rotate. When the nut 27 rotates, the threaded rod 23 is limited by the rotation of the limiting plate 24 and the limiting rod 25, preventing the threaded rod 23 from rotating along with it. This results in linear up-and-down movement, causing the threaded rod 23 to move upward. When the threaded rod 23 moves up and down, it can drive the hinge plate 43 to move together, thereby causing the support plate 41 to move up and down, adjusting the height of the support plate 41 so that it can be adapted to different heights as needed.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
