[0028] It should be noted that the massage component can select the structure of a massage stick in the prior art, so that the massage stick can perform tapping massage on the patient's forearm.

[0029] It should also be noted that the forearm support plate 3 is tilted in the initial state, and the tilting direction is toward the push plate 15. When the patient's forearm is pressed onto the forearm support plate 3, the forearm support plate 3 rotates on the support shaft 16 and is driven to reset by two torsion springs 17.

[0030] In this embodiment, the working principle of the arm support for patients undergoing thoracic surgery is as follows: the bed is pushed between the two limit rods 24, and then the motor five 23 is started. The motor five 23 drives the two-way screw two 22 to rotate. As the two-way screw two 22 rotates, the two limit rods 24 approach each other, and the two limit openings can cover the two legs of the bed. According to the comfortable angle of the patient's two upper arms, the motor three 13 is started, and the motor three 13 drives the rotating shaft 12 to rotate. As the rotating shaft 12 rotates, the two upper arm support plates 2 rotate accordingly, so that the two upper arm support plates 2 are at an angle where the patient's upper arms can be placed comfortably. Then, according to the length of the patient's arms, the electric cylinder 14 is started, and the electric cylinder 14 drives the forearm support plate 3 to move through the push plate 15. At this time, the patient is in The upper forearm is pressed onto the forearm support plate 3, and the forearm support plate 3 is subjected to the pressure of the patient's forearm. The fixed block drives the forearm support plate 3 to rotate around the support shaft 16. At this time, the two torsion springs 17 will be subjected to torsion until the patient's forearm is completely pressed onto the forearm support plate 3. When the patient reduces the pressure of the forearm on the forearm support plate 3 or the patient's forearm moves away from the forearm support plate 3, the two torsion springs 17 will bring the forearm support plate 3 to reset. After the patient places both arms, start the motor four 19, and the motor four 19 drives the bidirectional screw one 18 to rotate. As the bidirectional screw one 18 rotates, the two support shells 20 approach each other, so that the multiple massage components on the two support shells 20 clamp the patient's upper forearm, and then the patient's upper forearm is massaged through the massage component 21.

[0031] After the patient has been lying on his side in one direction for a long time, in order to prevent local skin from being compressed and increase the risk of pressure sores, the patient needs to turn over and lie on his side in another direction. After the patient changes his side-lying position, start motor 17, and motor 17 drives the drive shaft 9 to rotate in the support sleeve 8. At this time, the drive shaft 9 will drive the slider to move on the arc slide rail 5, thereby driving the two support blocks 11, the two upper arm support plates 2 and the forearm support plates 3 to rotate, so that the two upper arm support plates 2 and the forearm support plates 3 are rotated to the other side of the bed. At this time, the forearm support plate 3 will be located at the bottom, but because the patient's lower forearm is supported by the bed, the position of the forearm support plate 3 needs to be changed. At this time, start motor 2 10, and motor 2 10 drives the two support blocks 11 to rotate, so that the two support blocks 11 change their positions, and the two upper arm support plates 2 and the forearm support plates 3 rotate with them, so that the forearm support plates 3 are rotated to the top.

[0032] It should be noted that the fixed housing 1 can be embedded in the wall, which can save the installation space of the arm bracket to a certain extent.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
