[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0031] Please refer to Figure 1-6 , a hand support for a hospital bed, including a fixed adjustment device 2 and a fixing piece 3. The fixed adjustment device 2 is fixedly installed on the railing of the hospital bed through the fixing piece 3. The fixed adjustment device 2 serves as an intermediate component connecting the hospital bed railing and the hand support plate 1. One side is fixed on the hospital bed railing through the fixing piece 3, and the other side is installed with the hand support plate 1 and allows the angle of the hand support plate 1 to be adjusted to achieve the effect of adjusting the angle of the affected arm of the patient. The fixed adjustment device 2 not only provides a stable support foundation to ensure the stability of the hand support plate 1 during the patient's use, but also can flexibly adjust the angle of the affected arm to promote the rehabilitation effect. The hand support plate 1 is detachably installed on the fixed adjustment device 2. The hand support plate 1 is used to carry the affected arm, and the fixed adjustment device 2 is used to fix and adjust the angle of the hand support plate 1.
[0032] The fixed adjustment device 2 includes a semi-circular tube 21. The semi-circular tube 21 is wrapped around the hospital bed railing, providing a certain positioning function and facilitating the subsequent winding, sliding and fixing of the fixing piece 3 on the semi-circular tube 21. Ensure the stability and strength of the entire fixed adjustment device 2, so that it can be firmly fixed on the hospital bed railing. Both ends of the semi-circular tube 21 respectively extend out with a bracket one 22 and a bracket two 28, and the bracket one 22 and the bracket two 28 respectively provide an installation foundation for the card one 23 and the limit frame 24.
[0033] A first bracket 22 is provided with a first card 23, and a first rotating shaft 232 is provided on the first card 23. The first rotating shaft 232 is rotatably assembled on the first bracket 22. Since it is necessary to adjust the angle of the affected arm, during the process of adjusting the affected arm, the hand support plate 1 needs a rotation center. At this time, the first rotating shaft 232 on the first card 23 is rotatably assembled on the first bracket 22. When the positioning groove 15 of the hand support plate 1 is stuck on the first card 23, the hand support plate 1 can rotate around the first rotating shaft 232 under the adjustment of the adjustment knob 251, so as to achieve the effect of adjusting the angle.
[0034] A second bracket 28 is provided with a limiting frame 24 perpendicular to the semi-circular tube 21. Limiting grooves 241 are provided on both sides of the limiting frame 24, and a lead screw 25 is provided inside the limiting frame 24. An adjustment knob 251 is provided at the end of the lead screw 25. A slider 27 is provided on the lead screw 25, and limiting blocks 271 are provided on both sides of the slider 27. The limiting blocks 271 are assembled in the limiting grooves 241. The limiting frame 24, the lead screw 25 and the slider 27 form a lead screw 25 transmission mechanism, which is prior art and will not be elaborated here.
[0035] A second card 26 is provided on the side of the slider 27 close to the outside, and a second rotating shaft 262 is provided on the second card 26. The second rotating shaft 262 is rotatably provided on the slider 27. The second card 26 is rotatably installed on the slider 27 through the second rotating shaft 262. When the slider 27 moves upward under the rotation of the lead screw 25, the slider 27 drives the second card 26 thereon to move upward, and one end of the main board 11 installed on the second card 26 is also correspondingly lifted, so that the main board 11 is lifted upward around the second rotating shaft 262, thereby realizing the adjustment of the angle of the hand support plate 1.
[0036] The hand support plate 1 includes a main board 11. The upper top surface of the main board 11 is fixedly connected to the affected arm. A through groove 14 is provided on the side surface of the main board 11, and the through groove 14 is used for passing through the arm sling. When the patient lies in bed, it is often necessary to hang the arm on the neck through the arm sling, by directly fixedly connecting the upper top surface of the main board 11 to the plaster or the bottom of the affected arm. When the patient is not lying down, pass the arm sling through the through groove 14 and then rotate it around the neck to achieve the effect of raising the arm and accelerating recovery.
[0037] At both ends of the lower bottom surface of the main board 11, a square hoop one 12 and a square hoop two 13 are fixedly arranged respectively. A positioning groove 15 is formed between the square hoop one 12 and the lower bottom surface of the main board 11, and a sliding groove 16 is formed between the square hoop two 13 and the lower bottom surface of the main board 11. The positioning groove 15 and the sliding groove 16 are respectively installed through the card one 23 and the card two 26. The positioning groove 15 and the sliding groove 16 formed between the square hoop one 12 and the square hoop two 13 and the lower bottom surface of the main board 11 enable the patient to directly install the affected arm on the card one 23 and the card two 26 through the positioning groove 15 and the sliding groove 16 from the side, so as to fix the arm, which is more convenient and fast. The length of the sliding groove 16 is greater than that of the positioning groove 15. During the process of installing the positioning groove 15 and the sliding groove 16 on the card one 23 and the card two 26, since the affected arm needs to be fixed and is in a rehabilitation state, the patient often has unstable control. Therefore, during the process of inserting the card one 23 into the positioning groove 15, a certain stability is required. During the process of inserting the card two 26 into the sliding groove 16, since the length of the sliding groove 16 is greater than that of the positioning groove 15, the card two 26 can be inserted into the sliding groove 16 more easily. In addition, the reason for the longer length of the sliding groove 16 is that during the process of the main board 11 rotating upward around the rotating shaft one 232 from a parallel state, the card two 26 should not be fixed in the sliding groove 16, but should move from the end close to the positioning groove 15 to the end far from the positioning groove 15 in the sliding groove 16. Therefore, the length of the sliding groove 16 is longer, which is also to give the card two 26 a sufficient moving space during the process of adjusting the angle of the main board 11.
[0038] A relief groove one 231 is arranged on the support one 22, and a relief groove two 261 is arranged on the support two 28. The relief groove one 231 and the relief groove two 261 are used for clamping and installing the main board 11 thereon. After installing the main board 11 on the card one 23 and the card two 26 through the positioning groove 15 and the sliding groove 16, the patient moves the affected arm to make the main board 11 as close as possible to the inner sides of the card one 23 and the card two 26. After the main board 11 is close to the inner sides of the card one 23 and the card two 26, the patient naturally relaxes the affected arm, so that the affected arm is naturally placed under the action of gravity. At this time, the main board 11 will be stuck into the relief groove one 231 and the relief groove two 261, fixing the main board 11 on the card one 23 and the card two 26 to prevent the patient's arm from slipping off and causing secondary injuries. When the main board 11 needs to be removed, the patient lifts the affected arm upward by a certain distance to make the main board 11 disengage from the relief groove one 231 and the relief groove two 261, and then translates the main board 11 out of the card one 23 and the card two 26 outward through the positioning groove 15 and the sliding groove 16. The installation and removal of the hand support plate 1 can be completed more conveniently and quickly.
[0039] The fixing member 3 includes a first semi-ring 31 and a second semi-ring 32. One ends of the first semi-ring 31 and the second semi-ring 32 are rotatably connected by a hinge shaft 33. During the process of installing the fixing member 3 on the semi-circular tube 21, the first semi-ring 31 and the second semi-ring 32 are rotated open through the hinge shaft 33 and then clamped on the semi-circular tube 21. The other ends of the first semi-ring 31 and the second semi-ring 32 are connected by a locking bolt 35. A tightening handle 36 is arranged on the outer side of the locking bolt 35. After the first semi-ring 31 and the second semi-ring 32 are clamped on the semi-circular tube 21, the locking bolt 35 is tightened through the tightening handle 36, so as to fixedly connect the semi-circular tube 21 and the hospital bed railing together.
[0040] Fitting pieces 34 are arranged on the inner sides of the other ends of the first semi-ring 31 and the second semi-ring 32. During the process of installing the fixing member 3, it is necessary to make the fitting pieces 34 located at the opposite vacancies of the semi-circular tube 21. Because after the semi-circular tube 21 is attached to the hospital bed railing and then fixed by the fixing member 3, due to the thickness problem of the semi-circular tube 21 itself on the other side of the semi-circular tube 21, it is very difficult for the fixing member 3 to tightly press the hospital bed railing on this side. Therefore, by arranging the fitting pieces 34 inside the first semi-ring 31 and the second semi-ring 32, the fitting pieces 34 compensate for the other side of the semi-circular tube 21, so that the fixing member 3 can more firmly fix the semi-circular tube 21 on the hospital bed railing.
[0041] Working principle: During the process of applying a plaster cast to the patient's arm, the upper top surface of the main board 11 is fixed to the bottom of the plaster cast. When in use, first place the semi-circular tube 21 against the hospital bed railing, and make the first bracket 22 and the second bracket 28 face the inside of the hospital bed. Then open the first semi-ring 31 and the second semi-ring 32 so that the entire fixing member 3 surrounds the semi-circular tube 21 and the railing, and make the fitting piece 34 located on the opposite side of the semi-circular tube 21. Tighten the handle 36 to lock the locking bolt 35, so that the first semi-ring 31 and the second semi-ring 32 press and fix the semi-circular tube 21 on the railing. When the patient is lying in bed, align the positioning groove 15 with the first card 23 and the sliding groove 16 with the second card 26. Insert the first card 23 and the second card 26 into the positioning groove 15 and the sliding groove 16 respectively, and then relax the arm naturally so that the main board 11 is respectively clamped into the first relief groove 231 and the second relief groove 261, thereby realizing the fixation of the hand support plate 1. After the hand support plate 1 is fixed, if it is necessary to adjust the angle of the affected arm, rotate the adjustment knob 251 to drive the lead screw 25 to rotate, thereby driving the slider 27 to slide up and down, further driving the second card 26 to move up and down, so that the main board 11 makes an angle adjustment around the first rotating shaft 232, thereby realizing the adjustment of the angle of the affected arm. When the patient gets out of bed and needs to remove the affected arm, slightly lift the affected arm upward so that the main board 11 disengages from the first relief groove 231 and the second relief groove 261, and then smoothly draw out the affected arm in a direction parallel to the connection line of the first card 23 and the second card 26. After the hand support plate 1 is detached from the fixed adjustment device 2, the arm sling can be passed through the through groove 14, and the arm can be hung on the neck and fixed at a raised position. Thus, the effects of convenient placement, reliable fixation, adjustable arm angle, and auxiliary hanging of the arm on the neck are achieved.
