TECHNICAL FIELD
[0001] The utility model relates to an adjustable lower limb lifting pad and belongs to the technical field of medical nursing appliances. BACKGROUND
[0002] When nursing lower limb operation and trauma patients, the lower limbs of the patients usually need to be lifted to promote venous return and reduce the pressure of lower limb blood vessels, which is of great significance to promote postoperative recovery of the lower limbs. The slope of the lower limb lifting is generally about 30 degrees, and too high a slope will affect venous blood supply, and too low a slope will affect venous return. However, in clinical work, the angle at which the lower limbs need to be lifted is different due to the differences in age, body type and height of patients. The angle of the lower limb pad currently used in clinical practice is fixed and cannot be adjusted according to different patients, and thus the best lifting effect cannot be achieved.
[0003] In addition, for patients recovering from surgery, supine hip and knee flexion exercise has the following effects: 1. Muscle contraction: supine hip and knee flexion exercise is beneficial to the contraction of muscles around the joint, which helps to stabilize the joint and exercise the muscles. 2. Exercise of the waist bearing capacity: supine hip and knee flexion exercise is beneficial to the bearing of part of the weight by the waist muscles, thereby improving the body stability. However, the lower limb pad currently used in clinical practice can only be used for straight leg lifting and cannot allow patients to perform hip and knee flexion exercise. SUMMARY

Specific embodiments
[0022] The utility model will be further explained in connection with specific drawing and embodiment.
[0023] As shown in Figures 1-5 The embodiment discloses an adjustable lower limb lifting pad, which is mainly composed of base 1, first supporting plate 2, first adjustable support 3, first support wheel 4, first angle measuring device 5, second supporting plate 6, second adjustable support 7, second support wheel 8, second angle measuring device 9, soft pad 10, first slot rail 11, second slot rail 12, linkage lock rod 13, elastic spring piece 14, handle 15, clamping block 16 and other components.
[0024] The rear end of the first supporting plate 2 is pivotally connected with the rear end of the base 1, a first adjustable supporting piece 3 for adjusting the lifting angle of the first supporting plate 2 is arranged between the first supporting plate 2 and the base 1, the first adjustable supporting piece 3 is a telescopic rod, the lower end of the first adjustable supporting piece 3 is fixedly installed on the base 1, the upper end of the first adjustable supporting piece 3 is installed with a first supporting wheel 4, the bottom of the first supporting plate 2 is provided with a first wheel groove 2a, the first supporting wheel 4 is movably embedded in the first wheel groove 2a, and a first angle measuring device 5 is arranged at the pivot connection position of the first adjustable supporting piece 3 and the first supporting plate 2; the rear end of the second supporting plate 6 is pivotally connected with the front end of the first supporting plate 2, a second adjustable supporting piece 7 for adjusting the lifting angle of the second supporting plate 6 is arranged between the second supporting plate 6 and the base 1, the second adjustable supporting piece 7 is also a telescopic rod, the lower end of the second adjustable supporting piece 7 is fixedly installed on the base 1, the upper end of the second adjustable supporting piece 7 is installed with a second supporting wheel 8, the bottom of the second supporting plate 6 is provided with a second wheel groove 6a, the second supporting wheel 8 is movably embedded in the second wheel groove 6a, and a second angle measuring device 9 is arranged at the pivot connection position of the second supporting plate 6 and the first supporting plate 2.
[0025] In use, the patient takes a supine position, the adjustable lower limb lifting pad is placed under the lower limbs of the patient, the thighs of the patient are placed on the first supporting plate 2, the calves are placed on the second supporting plate 6, and the popliteal fossa corresponds to the pivot connection position of the first supporting plate 2 and the second supporting plate 6. When the adjustable lower limb lifting pad is used for straight leg raising of the lower limbs, the first adjustable supporting piece 3 and the second adjustable supporting piece 7 are both elongated, so that the first supporting plate 2 and the second supporting plate 6 are both lifted upwards and kept in the same plane
see Figure 1
see Figure 2
[0026] In the utility model, the telescopic rod serving as the first adjustable supporting piece 3 and the second adjustable supporting piece 7 can adopt a commercially available electric push rod or hydraulic rod. The first angle measuring device 5 and the second angle measuring device 9 can adopt a commercially available digital display angle measuring ruler. In addition, in order to improve the use comfort of the patient, the upper surfaces of the first supporting plate 2 and the second supporting plate 6 are both provided with soft pads 10.
[0027] In order to reduce the adjustment complexity when using this application for straight leg raising, we also set a synchronous locking mechanism between the first support plate 2 and the second support plate 6. The synchronous locking mechanism can connect the first support plate 2 and the second support plate 6 into a synchronously moving whole. In this way, the angle of the lower limb straight leg raising can be adjusted independently by using the first adjustable support member 3 or the second adjustable support member 7, making the operation more convenient.
[0028] like Figures 3-5 As shown, in this utility model, the synchronous locking mechanism mainly includes a first groove rail 11, a second groove rail 12, and a linkage locking rod 13. The first groove rail 11 is fixedly installed at the bottom of the first support plate 2, and the second groove rail 12 is fixedly installed at the bottom of the second support plate 6. The linkage locking rod 13 is slidably installed in the first groove rail 11 or the second groove rail 12. Both the first groove rail 11 and the second groove rail 12 are T-shaped groove rails. The linkage locking rod 13 is located in the wide slot of the T-shaped groove rail. The narrow slot edge of the T-shaped groove rail is provided with a rack portion. The linkage locking rod 13 is provided with an outwardly curved elastic spring 14. A handle 15 is installed on the elastic spring 14, and a locking block 16 is installed at the end of the elastic spring 14. When the elastic spring 14 is not subjected to external force, the locking block 16 is locked in a tooth of the rack portion to fix the linkage locking rod 13. When the linkage locking rod 13 is located alone in the first groove rail 11 or the second groove rail 12, the first support plate 2 and the second support plate 6 can rotate relative to each other. When it is necessary to connect the first tray 2 and the second tray 6 into a whole, pinch the handle 15 and press the elastic spring 14 inward to disengage the locking block 16 at the end of the elastic spring 14 from the rack. Then, use the handle 15 to drive the linkage locking rod 13 to move, so that the two ends of the linkage locking rod 13 are respectively located in the first groove 11 and the second groove 12, thereby connecting the first tray 2 and the second tray 6 into a synchronously moving whole.
[0029] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model.
