Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, and more specifically, it relates to a CT coronary angiography armrest. Background Art
[0002] When a patient undergoes CT coronary angiography, the patient generally lies flat on the bed and raises the hand above the head so that the doctor can operate. Currently, when performing CT coronary angiography, an armrest is generally provided to assist in supporting the patient's arm and relieve the patient's fatigue. However, most of the current armrests are arranged parallel to the bed, that is, the patient needs to raise the arm completely. However, for some older patients, the shoulder joint mobility is limited and they cannot raise the arm completely. At this time, the arm cannot be adapted to the existing armrests; in addition, the shoulder widths of different patients are different, so the distance requirements between the two armrests are also different. The current armrests are difficult to adapt to people of various heights. Content of the Utility Model

[0030] Please refer to Figures 1-7, a CT coronary angiography armrest 2, including a neck rest 1. Armrests 2 are provided on both sides of the neck rest 1. A first adjustment device and a second adjustment device are provided between the armrest 2 and the neck rest 1. The first adjustment device includes a moving block 3, a connecting plate 4, a limiting rod 5, a first limiting clamp 6 and a second limiting clamp 7. A moving groove 8 that cooperates with the moving block 3 is provided in the neck rest 1, and a first limiting hole 9 that cooperates with the limiting rod 5 is also provided in the neck rest 1. Both the moving block 3 and the limiting rod 5 are fixedly connected to the connecting plate 4. Both the first limiting clamp 6 and the second limiting clamp 7 are sleeved outside the limiting rod 5. The first limiting clamp 6 is fixedly connected to the neck rest 1. The second limiting clamp 7 is rotatably connected to one side of the first limiting clamp 6 and is detachably connected by a bolt on the other side. The second adjustment device includes a fixed rod 10, a fixed shaft 11 and a fixed sleeve 12. The fixed rod 10 is fixedly provided on the side of the connecting plate 4 away from the limiting rod 5, and a second limiting hole 13 that cooperates with the fixed rod 10 is provided in the armrest 2. A groove 24 is provided on the upper surface of the armrest 2. Rubber pads 25 are provided on the inner sides of both the first limiting clamp 6 and the second limiting clamp 7, and the rubber pads 25 are in contact with the limiting rod 5. Both the first adjustment device and the second adjustment device are provided with two groups and are symmetrically arranged on both sides of the neck rest 1.
[0031] In this embodiment, place the device on the bed surface. The patient lies on the bed and places the neck on the neck rest 1, and raises the arm upwards. Adjust the position of the armrest 2 according to the patient's shoulder width. When adjusting, first loosen the bolt between the first limiting clamp 6 and the second limiting clamp 7, and pull or push the connecting plate 4, the moving block 3 and the limiting rod 5 outwards or inwards until the armrest 2 moves to a suitable position. At this time, tighten the bolt between the first limiting clamp 6 and the second limiting clamp 7, and clamp and fix the limiting rod 5 through the rubber pad 25 between the first limiting clamp 6 and the second limiting clamp 7.
[0032] Please refer to Figures 1-7 , as an implementation manner of the second adjustment device: An avoidance hole 14 that cooperates with the fixed shaft 11 and the fixed sleeve 12 is provided on one side of the second limiting hole 13. The fixed shaft 11 and the fixed sleeve 12 are slidably arranged in the avoidance hole 14. A first limiting groove 15 is provided outside the fixed rod 10, and second limiting grooves 16 are provided in both the second limiting hole 13 and the avoidance hole 14. A first limiting protrusion 17 that cooperates with the first limiting groove 15 is provided on the inner wall of the fixed sleeve 12, and a second limiting protrusion 18 that cooperates with the second limiting groove 16 is provided on the outer wall of the fixed sleeve 12. A fixed ring 19 is provided on one side of the armrest 2. A first insertion hole 20 is provided in the fixed ring 19, a second insertion hole 21 is provided on the fixed shaft 11, and a plug rod 22 is slidably arranged in the first insertion hole 20 and the second insertion hole 21. A pull ring 23 is provided at one end of the plug rod 22 away from the fixed shaft 11.
[0033] More specifically, the inclination angle of the armrest 2 is adjusted according to the patient's arm extension. During the adjustment, first pull out the insertion rod 22 from the first jack 20 and the second jack 21, and pull the fixed shaft 11 outwards to disengage the fixed sleeve 12 from the fixed rod 10. At this time, the armrest 2 can be rotated, driving the fixed shaft 11 and the fixed sleeve 12 to rotate together until the armrest 2 rotates to the appropriate angle. Then, push the fixed shaft 11 to reinsert the fixed sleeve 12 between the fixed rod 10 and the armrest 2, so that the first limiting protrusion 17 on the fixed sleeve 12 cooperates with the first limiting groove 15 outside the fixed rod 10 to fix the armrest 2 and the fixed rod 10, and reinsert the insertion rod 22 into the first jack 20 and the second jack 21 to prevent the fixed shaft 11 from sliding outwards accidentally and causing the armrest 2 to become loose.
[0034] In summary, when the overall device is in use or operation: place the device on the bed surface, let the patient lie on the bed and place the neck on the neck rest 1, lift the arm upwards, and adjust the position of the armrest 2 according to the patient's shoulder width. During the adjustment, first loosen the bolt between the first limiting clamp 6 and the second limiting clamp 7, and pull or push the connecting plate 4, the moving block 3, and the limiting rod 5 outwards or inwards until the armrest 2 moves to the appropriate position. Then, tighten the bolt between the first limiting clamp 6 and the second limiting clamp 7, and clamp and fix the limiting rod 5 through the rubber pad 25 between the first limiting clamp 6 and the second limiting clamp 7.
[0035] More specifically, the inclination angle of the armrest 2 is adjusted according to the patient's arm extension. During the adjustment, first pull out the insertion rod 22 from the first jack 20 and the second jack 21, and pull the fixed shaft 11 outwards to disengage the fixed sleeve 12 from the fixed rod 10. At this time, the armrest 2 can be rotated, driving the fixed shaft 11 and the fixed sleeve 12 to rotate together until the armrest 2 rotates to the appropriate angle. Then, push the fixed shaft 11 to reinsert the fixed sleeve 12 between the fixed rod 10 and the armrest 2, so that the first limiting protrusion 17 on the fixed sleeve 12 cooperates with the first limiting groove 15 outside the fixed rod 10 to fix the armrest 2 and the fixed rod 10, and reinsert the insertion rod 22 into the first jack 20 and the second jack 21 to prevent the fixed shaft 11 from sliding outwards accidentally and causing the armrest 2 to become loose.
