Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, in particular to an adjustable intelligent lifting pad. Background Art
[0002] When providing clinical treatment for patients with lower limb trauma, lower limb venous vascular disease, lower limb lymphatic disease, etc., raising the lower limbs is one of the nursing methods often used in treatment to promote venous blood return, reduce lower limb swelling and patient pain, and the lower limbs need to be raised according to the treatment requirements.
[0003] One of the traditional nursing methods is to use quilts, pillows or clothes to pad under the patient's lower limbs. When using this method, the quilts, pillows or clothes are prone to depression and cannot keep the lower limbs elevated. Moreover, if the padding is too high or too low, the patient's lower limbs will be too high or too low, affecting blood circulation and causing discomfort to the patient.
[0004] Another nursing method is to directly suspend the patient's lower limbs with an apparatus. However, when this method is adopted, the patient's lower limbs are prone to stiffness after a long time, and the patient is uncomfortable.
[0005] At present, the beds provided by hospitals can raise the patient's lower limbs by raising the foot of the bed. However, when raising the foot of the bed, the height is difficult to control, the width of the raised part of the bed is uniform, and both legs of the patient are raised. It is difficult for people with poor cardiopulmonary function to tolerate it, and it lacks specificity. Moreover, the raised part of the bed makes the height of the front and back of the raised surface consistent, which is not conducive to venous return and affects the treatment effect. Some patients with mild varicose veins in the lower limbs or patients in the recovery period after lower limb surgery still need to raise their lower limbs at home. There is no raised bed at home. The lower limb raising pad can meet the needs of these patients.
[0006] Therefore, the present invention proposes an adjustable intelligent lifting pad to solve the above problems. Summary of the invention
