[0024] Example 1, as shown in the attached document Figures 1-4 As shown

[0025] This adjustable upper limb pad includes a base plate 1 and a pad plate 2. The base plate 1 is stepped, and a support boss 3 is provided at one end of the upper surface of the base plate 1. The pad plate 2 is movably mounted to one end of the support boss 3 via a hinge 4. An angle adjustment component is provided between the base plate 1 and the pad plate 2. The angle adjustment component can drive the pad plate 2 to rotate around the hinge 4, thereby adjusting the tilt angle of the pad plate 2. The angle adjustment component is composed of a screw mechanism provided on the base plate 1 on one side of the support boss 3. The screw mechanism consists of a transmission screw 5 and a screw nut 6. The transmission screw 5 is movably mounted on the base plate 1 via a mounting plate. A transmission handwheel 7 is fixedly mounted at one end of the transmission screw 5, and a mounting block 8 is provided on the top of the screw nut 6 on the transmission screw 5.

[0026] Rollers 9 are provided on both sides of the mounting block 8. A slide rail 10 is fixedly installed on the bottom of the pad 2 corresponding to the rollers 9. A limiting ring groove 11 is provided on the circumference of the rollers 9. The rollers 9 are slidably connected to the pad 2 through the cooperation of the limiting ring groove 11 and the slide rail 10.

[0027] The support boss 3 and the upper surface of the pad plate 2 of the upper limb pad are respectively provided with recesses in communication with each other, and the recesses of the pad plate 2 are symmetrically provided with magic tape bands 12 on both sides. These designs improve the safety of treatment and the comfort of patients. The recess design makes the limbs naturally embedded and limits the range of movement. During use, the upper limbs of the patients are fixed to avoid the risk of internal fistula injury and bleeding or needle removal caused by movement and traction of the punctured limbs. The recess arc structure fits the limb curve to avoid local pressure and reduce the risk of pressure sores. The recess is movably provided with a gasket made of textile material or sponge to increase the softness of the recess. In winter, a commercially available heating warm pad can be laid at the bottom of the gasket to avoid the upper limbs of the patients from being cold. The magic tape band fixing can be flexibly adjusted in tightness.

[0028] When the upper limb pad is used, the transmission hand wheel 7 drives the transmission lead screw 5 to rotate. The transmission lead screw 5 cooperates with the lead screw nut 6 to change the rolling wheel 9 on the mounting block 8 to slide along the sliding rail 10, so that the rolling wheel 9 and the sliding rail 10 cooperate to top support the pad plate 2 to achieve stepless adjustment of the inclination angle.

[0029] As an improvement of the angle adjusting part, a top rod 17 can be movably installed on the top of the lead screw nut 6 through a pin shaft. The other end of the top rod 17 is connected to the bottom of the pad plate 2 through an ear plate and a pin shaft (see FIG. 4). Figure 5 .

[0030] During use, the rotation of the transmission hand wheel 7 drives the lead screw nut 6 to move on the transmission lead screw 5, and drives the top rod 17 to gradually lift the pad plate 2, so as to achieve the purpose of adjusting the inclination angle of the pad plate 2.

[0031] Embodiment 2, as shown in FIGS. 5 and 6, Figure 6 , 7

[0032] The upper limb pad with convenient inclination angle adjustment comprises a bottom plate 1 and a pad plate 2. The bottom plate 1 is in a stepped shape. The upper surface of the bottom plate 1 is provided with a support boss 3 at one end. The support boss 3 is movably provided with the pad plate 2 through a hinge 4 at one end. An angle adjusting part is arranged between the bottom plate 1 and the pad plate 2. The angle adjusting part can drive the pad plate 2 to rotate around the hinge 4 to adjust the inclination angle of the pad plate 2. The angle adjusting part is composed of symmetrical ratchet tooth rings 13 fixed on both sides of the support boss 3 and ratchet teeth 14 fixed on both sides of the pad plate 2 and connected with the ratchet tooth rings 13. The ratchet teeth 14 are movably installed on the pad plate 2 through a short shaft. The outer side of one end of the ratchet teeth 14 is provided with a pressing handle 15. The pad plate 2 below the ratchet teeth 14 is provided with an elastic sheet 16 through a mounting column. One end of the elastic sheet 16 is in contact with the ratchet teeth 14.

[0033] ​The support boss 3 and the upper surface of the pad plate 2 of the upper limb pad are respectively provided with recesses which are in communication with each other; the recesses on both sides of the pad plate 2 are symmetrically provided with straps 12 to strengthen the limiting effect of the recesses. A gasket is movably arranged in the recess; the gasket is made of textile material or sponge to increase the softness of the recess. In winter, a commercially available heating pad can be laid at the bottom of the gasket to avoid the upper limbs of the patient from being chilled.

[0034] The upper limb pad realizes stepless adjustment of the inclination angle of the pad plate 2 by lifting the end of the pad plate 2 to make it turn over about the hinge 4; in this process, the pad plate 2 drives the ratchet 14 to slide on the tooth surface of the ratchet gear teeth 13; when the pad plate 2 stops turning over, the ratchet 14 and the ratchet gear teeth 13 form engagement under the action of the elastic sheet 16, and the inclination angle is fixed. When it is needed to reversely turn over the pad plate 2, the engagement state of the ratchet 14 and the ratchet gear teeth 13 is released by pressing the pressing handle 15, and the pad plate 2 is reset under the action of its own weight.
