[0035] At present, there are patients with impaired motor functions in some hospitals, who need to lie on nursing beds for treatment and recuperation. During the treatment of such patients, since the patients spend a long time in bed, in order to prevent the patients' arms from becoming stiff, they need to undergo certain training on their arms, etc., so as to improve the efficiency of rehabilitation. However, since the motor functions of such patients are impaired, external force is needed to help the patients lift or put down their arms. However, in the relevant technologies, the functions of nursing beds are single, and they mainly focus on basic nursing functions, such as lifting, turning, etc., which cannot meet the needs of use. Manually helping patients lift or put down their arms will increase the burden on caregivers.

[0036] To solve this problem, the first embodiment of the utility model provides an arm rehabilitation device 1000, which can lift and lower the patient's arm by utilizing the cooperation of a rotating component and an arm grasping component. While improving the patient's rehabilitation efficiency, it also reduces the burden on caregivers. The specific structure and function of the arm rehabilitation device 1000 provided in the embodiment of the utility model will be further explained below with reference to text and drawings.

[0037] Reference Figure 1 and Figure 2 According to the first aspect of the present invention, the arm rehabilitation device 1000 provided by the embodiment includes: a shell 100 and an arm grasping structure, the arm grasping structure includes a rotating component and an arm grasping component; the rotating component includes a first connecting seat 110 and a first motor 120, the first connecting seat 110 is arranged in the shell 100, and the first motor 120 is fixedly connected to the first connecting seat 110; the arm grasping member includes a second connecting seat 130, a second motor 140 and a flexible clamp 150, the second connecting seat 130 has a bending portion, the bending portion of the second connecting seat 130 is rotatably connected to the first connecting seat 110, and the second motor 140 and the flexible clamp 150 are both connected to the second connecting seat 130; wherein the first motor 120 is connected to the second connecting seat 130, the first motor 120 is configured to be able to drive the second connecting seat 130 to rotate, the second motor 140 is connected to the flexible clamp 150, and the second motor 140 is configured to be able to drive the flexible clamp 150 to open or close.

[0038] According to the arm rehabilitation device 1000 provided in the embodiment of the first aspect of the utility model, by applying the arm rehabilitation device 1000 on the nursing bed, when it is necessary to perform certain training on the patient's arms, etc., the patient's arms can be placed in the flexible clamp 150 in the open state, and then the second motor 140 can drive the flexible clamp 150 to close. After the flexible clamp 150 clamps the patient's arm, the first motor 120 arranged on the first connecting seat 110 is started, and the first motor 120 can drive the second connecting seat 130 to rotate. The rotation of the second connecting seat 130 can drive the flexible clamp 150 to rotate. The rotation of the flexible clamp 150 can drive the patient's arm to rotate together, thereby realizing the lifting and lowering of the patient's arm. The arm rehabilitation device 1000 provided in the embodiment of the utility model can realize the lifting and lowering of the patient's arm by using the cooperation of the rotating component and the arm grasping component, which not only improves the patient's rehabilitation efficiency but also reduces the burden on nursing staff.

[0039] Reference Figures 1 to 3 According to the arm rehabilitation device 1000 provided by the embodiment of the first aspect of the utility model, the arm grasping structure also includes a translation component, and the first connecting seat 110 is slidably connected to the shell 100. The translation component is configured to be able to drive the first connecting seat 110 so that the first connecting seat 110 can be translated along the length direction of the shell 100. During the translation of the first connecting seat 110, the arm grasping structure can be driven to move together, which can meet the needs of patients with different heights and different arm parts on the nursing bed.

[0040] It is understandable that when in use, the arm rehabilitation device 1000 is set on one side of the nursing bed, and the length direction of the housing 100 of the arm rehabilitation device 1000 coincides with the length direction of the nursing bed. When it is necessary to train the patient's arm, etc., if the position of the arm rehabilitation device 1000 is not appropriate, the translation component can be adjusted first to move the arm grasping structure to a suitable position of the patient's arm, and then the rotation component and the arm grasping component can be used to lift or lower the patient's arm.

The first connecting seat 110 is provided with a threaded hole. The linear screw 170 passes through the threaded hole and is threadedly connected to the inner wall of the threaded hole. The rotation of the rotating shaft of the third motor 160 can drive the linear screw 170 to rotate. The rotation of the linear screw 170 can drive the first connecting seat 110 to translate. The third motor 160 and the linear screw 170 are used to adjust the position of the arm grasping structure, and the adjustment method is stable and reliable.

[0042] It should be noted that since the linear screw 170 is threadedly connected to the first connecting seat 110, when the third motor 160 drives the linear screw 170 to rotate, it can achieve stepless adjustment of the connecting seat to facilitate adjusting the arm grasping structure to different positions on the nursing bed.

[0043] Reference Figure 3 According to the arm rehabilitation device 1000 provided by the first embodiment of the utility model, a slide rail (not shown in the figure) is arranged at the bottom of the shell 100, and a slide groove is arranged on the side of the first connecting seat 110 facing the slide rail, and the slide rail is passed through the slide groove, and the first connecting seat 110 can slide stably on the slide rail.

[0044] Reference Figure 2 and Figure 3 According to the arm rehabilitation device 1000 provided by the embodiment of the first aspect of the utility model, the first motor 120 is arranged at the top of the first connecting seat 110, and the driving connection of the first motor 120 is connected with the first bevel gear 121. A second bevel gear 131 is arranged at one end of the second connecting seat 130, and the first bevel gear 121 is meshed with the second bevel gear 131.
