DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] The utility model provides Figure 1-5 The adjustable arm bracket for left radial artery puncture angiography shown comprises a bottom plate 1, a base 2 mounted on the top of the bottom plate 1, a support rod 3 arranged on the top of the bottom plate 1 and passing through the base 2, and a lifting assembly arranged on the top of the support rod 3;

[0034] The lifting assembly includes a large arm support plate 41 disposed on the top of the support rod 3, a pin 42 connected to the end of the large arm support plate 41, a small arm support plate 43 connected to the large arm support plate 41 through the pin 42 and capable of rotating about the axis of the pin 42, and a hand support 44 installed on the top of the small arm support plate 43;

[0035] The support rod 3 can move left and right along the length direction of the base 2, which is convenient for doctors to adjust and use. The hand support 44 can move left and right along the top of the forearm support plate 43 to adapt to the arm lengths of different patients.

[0036] In one embodiment, a first slide groove 5 is provided on the top of the base 2, and a card slot 6 is provided on the inner wall of the base 2 located at the first slide groove 5. A card plate 7 that can move left and right along the card slot 6 is provided in the card slot 6 to ensure the stability of the support rod 3. The bottom of the support rod 3 passes through the card plate 7 and is connected to the card plate 7. A first adjusting rod 8 is installed on one side of the base 2. The first adjusting rod 8 passes through the support rod 3 horizontally. The first adjusting rod 8 and the support rod 3 are threadedly connected, so that when the first adjusting rod 8 rotates, the support rod 3 can be translated. The first adjusting rod 8 is connected to the base 2 through a bearing. Plane sections are milled on both sides of the front and rear ends of the bottom end of the support rod 3. The spacing between the two planar sections is adapted to the width of the first slide groove 5, which is convenient for the support rod 3 to move and prevent the support rod 3 from tilting back and forth. The support rod 3 above the planar section will have a corresponding protrusion, which can be placed above the opening of the slide groove, thereby ensuring the stability of the support rod 3.

[0037] In one embodiment, a second slide groove 9 is opened on the top of the forearm support plate 43, and a moving block 10 is arranged inside the second slide groove 9. The bottom of the hand rest 44 is connected to the top of the moving block 10. A second adjusting rod 11 is installed on one side of the forearm support plate 43. The second adjusting rod 11 is arranged to penetrate the moving block 10 horizontally. The second adjusting rod 11 and the moving block 10 are arranged to be threadedly connected, so that when the second adjusting rod 11 is rotated, the hand rest 44 can be translated, and the second adjusting rod 11 is connected to the forearm support plate 43 through a bearing.

[0038] In one embodiment, the hand rest 44 is configured as an oblique triangle to facilitate the placement of the patient's palm, and the top oblique surface is concave with an arc-shaped surface. The top of the upper arm support plate 41 is also concave with an arc-shaped surface, which can support the patient's arm and has a certain limiting function to ensure that the patient's arm will not easily fall off the arm support.

[0039] In one embodiment, the top of the hand rest 44 and the opening of the upper arm support plate 41 are wrapped with elastic pads, and the opening of the upper arm support plate 41 is widened. Specifically, the elastic pad is configured as a silicone pad, a rubber pad or a sponge block, which can ensure the comfort of the patient's arm when placed.

[0040] In one embodiment, the cross-section of the pin shaft 42 is set to be T-shaped, and the top is set flush with the forearm support plate 43, and the pin shaft 42 and the forearm support plate 43 are set to be interference fit, so that the forearm support plate 43 has sufficient friction after being unfolded and is relatively stable when used.

[0041] In one embodiment, a reinforcing plate 12 is connected to the top of the support rod 3, and the upper arm support plate 41 is connected to the top of the support rod 3 through the reinforcing plate 12, thereby increasing the contact area between the support rod 3 and the upper arm support plate 41, making the upper arm support plate 41 more stable when in use, and the outer ends of the first adjusting rod 8 and the second adjusting rod 11 are both installed with a dial plate 13, which facilitates medical staff to rotate the first adjusting rod 8 or the second adjusting rod 11.

[0042] The specific implementation mode is as follows: when the utility model is used, the medical staff inserts the bottom plate 1 under the mattress of the hospital bed, presses it with the help of the patient's own gravity, and then puts the patient's right hand on the arm bracket. Specifically, the patient's upper arm is horizontally placed on the upper arm bracket 41, and the lower arm is horizontally placed on the lower arm push plate, and the palm of the hand is facing upward on the hand bracket 44. Then the hospital staff pushes the lower arm bracket 43 into the hospital bed, so that it rotates 20-30 degrees around the axis of the pin shaft 42, so that the patient's lower arm rotates to above the patient's navel. At this time, the medical staff can go around to the left side of the patient to perform radial artery puncture;

[0043] When the arm support is adjusted for use, the pin shaft 42 is set so that the forearm support plate 43 can be freely unfolded to change the angle between the forearm support plate 41 and the upper arm support plate 41, thereby improving the flexibility of the arm support. The pin shaft 42 and the forearm support plate 43 are set to be interference fit, so that the forearm support plate 43 has sufficient friction after being unfolded, and can remain stable under the condition of cooperating with the weight of the patient's arm.

[0044] The medical staff can rotate the dial plate 13 at the end of the first adjustment rod forward to drive the first adjustment rod 8 to rotate forward, so that the bottom of the support rod 3 moves to the left along the first slide groove 5, and rotate the first adjustment rod 8 in the reverse direction, the support rod 3 will move to the right along the first slide groove 5, thereby driving the upper arm support plate 41 to move to the left or right, which can better support the patient's upper arm, and the clamping plate 7 will simultaneously move to the left or right along the clamping groove 6 to ensure that the support rod 3 will not tilt horizontally, thereby ensuring that the upper arm support plate 41 is always horizontal and stable;

[0045] by Figure 2In the example, the forearm support plate 43 is not unfolded. Similarly, the medical staff can also rotate the dial plate 13 at the end of the second adjustment rod 11 forwardly to make the second adjustment rod 11 rotate forwardly, thereby moving the hand support 44 to the left, close to the upper arm support plate 41, and when the second adjustment rod 11 is rotated in the reverse direction, the hand support 44 can move to the right, away from the upper arm support plate 41, so that the position of the hand support 44 is freely variable and controllable, and can be adjusted according to the length of the patient's arm to ensure the comfort of the patient's palm when placed;

[0046] This embodiment specifically solves the problem that the current radial artery puncture arm bracket in the prior art has only a simple lifting function in actual use, cannot adjust the angle according to the raising of the patient's arm, has poor flexibility in use, and when the patient's arm is placed on the bracket, the bracket is pressed by the patient's torso, is inconvenient to move, cannot be adjusted in time according to the patient's arm length, and has low adaptability.

[0047] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
