Specifically, the stud 2 is driven to rotate by the rotation adjusting wheel 21, the rotation of the stud 2 drives the connecting block 3 to slide in the chute 11, and the movement of the connecting block 3 drives the arm support assembly 4 to move, so that the position adjustment of the arm support assembly 4 is realized. In the actual use process, the transmission box body 1 is fixed on the examination bedside, the connecting block 3 is driven to move by rotating the adjusting wheel 21, the moving Arbitrary arm support assembly 4 of the connecting block 3 moves, the position of the arm support assembly 4 is adjusted, the arm support assembly 4 is caused to be matched with the arm position of a patient, or the arm of the patient is in a comfortable state as far as possible. Because each person has different heights and different movement habits of limbs, different persons lie on the examination bed, and the positions where the arms are placed can be different, and the utility model adapts to different patients by adjusting the positions of the arm support assemblies 4. Meanwhile, the arm support assembly 4 is hinged with the connecting block 3, that is, the angle of the arm support assembly 4 can be adjusted to a certain degree while the position of the arm support assembly 4 is adjusted. Compared with the arm support plate in the prior art, the utility model can adjust the position of the arm support assembly 4 according to different positions of a patient, so as to reduce uncomfortable feeling of the patient in vascular intervention operation as much as possible, and at least avoid uncomfortable feeling caused by the position of the arm.

As an example, the arm support assembly 4 includes a base 41, an arc plate 42 and a fixing plate 43, the base 41 is hinged to the connection block 3, the arc plate 42 is fixedly mounted on the upper surface of the base 41, the fixing plate 43 is detachably disposed on the arc plate 42, a cylindrical fixing space is formed between the arc plate 42 and the fixing plate 43 for fixing to an arm, and the wrist support assembly 5 is disposed on the upper surface of the arc plate 42. The fixing space formed between the fixing plate 43 and the arc plate 42 is used to bind the arm of the patient, which can be also understood as confinement. Can effectively avoid the failure of vascular intervention operation caused by subconscious movement of arms of patients.

As an example, the upper surface of the circular arc plate 42 and the lower surface of the fixing plate 43 are respectively provided with a lower clamping plate 44 and an upper clamping plate 45, the lower clamping plate 44 is connected with the circular arc plate 42 through a first spring 46, and the upper clamping plate 45 is also connected with the fixing plate 43 through the first spring 46. Specifically, when the arc plate 42 and the fixing plate 43 bind the arm of the patient, the upper clamping plate 45 and the lower clamping plate 44 are attached to the arm of the patient, and clamp the arm of the patient, meanwhile, the springs 46 have certain elasticity, that is, the upper clamping plate 45 and the lower clamping plate 44 have certain movable space, so that the arm of the patient also has certain movable space, and the patient is prevented from being blocked by blood circulation caused by the over-tightening of the arm of the patient while the arm of the patient is bound.

As an example, the wrist support assembly 5 includes a support airbag 51, an exhaust valve 52, and an inflation assembly 53, where the support airbag 51 is disposed on the upper surface of the circular arc plate 42, the inflation assembly 53 is connected to the support airbag 51 through a pipeline, the inflation assembly 53 is used to inflate the support airbag 51, the exhaust valve 52 is connected to the support airbag 51, and the exhaust valve 52 is used to exhaust the internal gas of the support airbag 51. Specifically, the support airbag 51 is configured to support the wrist of the patient, and in actual use, the inflation assembly 53 may be used to inflate the support airbag 51, where the amount of air in the support airbag 51 determines the support height of the support airbag 51 on the wrist of the patient. That is to say, the wrist of the patient can be supported at different heights by adjusting the inflation amount of the inflation assembly 53, so that the wrist support can be suitable for different patients, and the wrist support can be effectively provided for the patients.

As an example, the inflation assembly 53 includes a cavity 531, a first check valve 532, a second check valve 533, a second spring 534, a piston 535, and a compression bar 536, where the first check valve 532 and the second check valve 533 are respectively connected to the cavity 531, the first check valve 532 is connected to the support airbag 51 through the pipe, the second spring 534 is connected to the piston 535, the piston 535 is disposed inside the cavity 531, the compression bar 536 is connected to the piston 535, and the compression bar 536 extends out of the cavity 531. Specifically, referring to fig. 3, in a normal state, the second spring 534 provides a downward elastic force for the piston 535, so that a certain space is formed between the piston 535 and the top wall of the cavity 531, when the support airbag 51 needs to be inflated, the compression bar 536 is pressed, the compression bar 536 moves upward, the piston 535 extrudes the internal air of the cavity 531 into the support airbag 51, then the pressure on the compression bar 536 is cancelled, the piston 535 moves downward under the restoring force of the second spring 534, at this time, the external air enters the cavity 531 through the second one-way valve 533, and then the compression bar 536 is pressed again to continuously inflate the support airbag 51, so that the support airbag 51 is reciprocated until the height of the support airbag 51 is suitable for the wrist of a patient. Wherein the first check valve 532 is used to prevent air in the support airbag 531 from flowing back into the cavity 531, and the second check valve 533 is used to prevent the internal air of the cavity 531 from flowing into the outside. The first check valve 532 and the second check valve 533 are conventional check valves, and will not be described in detail herein.

As an example, the transmission box 1 is provided with a connecting piece 12, and the connecting piece 12 is provided with a mounting hole 13. In practical use, the screw holes can be prepared at the side of the inspection bed, then the existing screws are used for penetrating through the mounting holes 13 and the screws and the prefabricated screw holes, and then the screws are screwed down, so that the transmission box body 1 is mounted.
