[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1-4 As shown, the technical solution adopted by the present invention is as follows: a limb exercise device for critically ill patients on bed, comprising a bracket 1 for fixing on the bed, and a plurality of exercise components are arranged on the bracket 1;

[0025] The various exercise components include a rectangular rotating block 2, two opposite vertical surfaces of the rectangular rotating block 2 are provided with first through holes, each of the first through holes is provided with a rotating rod 3, the two rotating rods 3 are rotatably arranged on the bracket 1, and the remaining four surfaces of the rectangular rotating block 2 are respectively provided with upper and lower stretching components, left and right stretching components, joint movement components, and width adjustment components.

[0026] In order to fix the entire device on the bed, a U-shaped frame 4 is provided at the bottom of the bracket 1, a threaded rod is threadedly provided on the U-shaped frame 4, and a fixed plate is provided at the bottom of the threaded rod. By rotating the threaded rod on the U-shaped frame 4, the fixed plate is driven to move downward, so that the entire device is fixed on the bed.

[0027] At the same time, the adjustment component can adjust the width of the bracket 1. The adjustment component includes a plurality of second through holes 5 provided on the rectangular rotating block 2. The second through holes 5 are connected to the first through holes. A third through hole 6 is provided on the rotating rod 3. A locking rod 7 is inserted into the third through hole 6 and the second through hole 5. When in use, the bracket 1 drives the rotating rod 3 to move inside the first through hole. When it moves to the desired position, the second through hole 5 and the third through hole 6 are aligned, and then the locking rod 7 is inserted to complete the effect of adjusting the width.

[0028] In the prior art, the width is generally adjusted by a threaded rod, but the threads on the threaded rod will be damaged during frequent use, and the fixation will be loose during subsequent use. Therefore, the utility model can increase the service life by setting an adjustment component without damage.

[0029] The locking rod 7 matches with the second through hole 5 and the third through hole 6. Matching here means that no shaking will occur during insertion.

[0030] like Figure 4 As shown, the upper and lower stretching components include a hollow cylinder 8 connected to the rectangular rotating block 2, a first spring 9 is arranged inside the hollow cylinder 8, a piston disk 10 is installed on one side of the first spring 9, a pull rope 11 is arranged on the piston disk 10, and the bottom of the pull rope 11 passes through the hollow cylinder 8 and is connected to a stretching ring 12.

[0031] When the patient is stretching up and down, he holds the stretching ring 12, and then the stretching ring 12 drives the piston disk 10 to stretch the first spring 9. The elastic force of the first spring 9 provides a certain resistance, thereby performing up and down stretching exercises. For patients who are bedridden for a long time, this exercise helps prevent muscle atrophy and joint stiffness.

[0032] like Figure 3-4 As shown, the left and right stretching components include two slide grooves 13 opened on the rectangular rotating block 2, each slide groove 13 is provided with a fixed shaft 14, the fixed shaft 14 is sleeved with a slider 15 and a second spring 16, the slider 15 slides left and right in the slide groove 13, the second spring 16 is provided on both sides of the slider 15, and a pulling rod 17 is provided at the bottom of the slider 15.

[0033] When in use, the patient holds the pulling rod 17, and the pulling rod 17 drives the slider 15 to squeeze the second spring 16 on the fixed shaft 14. The elastic force of the second spring 16 provides a certain resistance, which is mainly used for stretching exercises in the left and right directions. This exercise helps to enhance muscle strength and flexibility.

[0034] like Figure 4 As shown, the joint movable assembly includes a rotating shaft rotatably arranged on a rectangular parallelepiped rotating block 2, and a rotating disk 18 is arranged on the rotating shaft.

[0035] The patient drives the rotating shaft to rotate on the rectangular rotating block 2 through the rotating disk 18, thereby helping the patient to perform flexion, extension and rotation activities of the joints, which is very important for maintaining the flexibility of the joints and preventing joint stiffness.

[0036] like Figure 1 As shown, one end of one of the rotating rods 3 passes through the bracket 1 and is connected to the rotating disk. The rotating rod 3 is driven by the rotating disk to rotate the rectangular rotating block 2, so that the exercise method can be selected.

[0037] The working principle of the utility model is as follows: firstly, the bracket 1 is installed on the bed, and then the width of the two brackets 1 is adjusted by the adjustment component, so that it can adapt to beds of different widths, and then people can rotate the rectangular rotating block 2 by the rotating rod 3, so that various exercise methods can be selected, and the patient's limbs can be stretched up and down by the upper and lower stretching components, and the patient's limbs can be stretched left and right by the left and right stretching components, and the limb joints can be moved by the joint activity components, so as to effectively improve the exercise effect. The device integrates various limb exercises, can exercise the patient's limbs in multiple directions, improve the exercise effect, and can adapt to different patients, improving its practicality.

[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
