Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a device for the auxiliary treatment of non-alcoholic fatty liver disease. BACKGROUND

[0002] Non-alcoholic fatty liver disease is one of the most common chronic liver diseases in the world, with a global prevalence of about 25%. The disease is characterized by liver steatosis, which can further develop into non-alcoholic fatty liver hepatitis, liver fibrosis, even cirrhosis and liver cancer, and is often associated with obesity, type 2 diabetes, metabolic syndrome and other metabolic diseases. Due to the lack of effective drugs for the treatment of non-alcoholic fatty liver disease in China at present, lifestyle intervention is currently the most important treatment measure for fatty liver in clinical practice. In addition to diet control based on nutrition, aerobic exercise is also an important means of treating non-alcoholic fatty liver disease. Moderate and individualized aerobic exercise not only improves the cardiopulmonary function and physical fitness of patients, but also improves liver mitochondrial function, promotes lipid metabolism, increases insulin sensitivity, and consumes excess capacity, making it one of the most effective treatment methods for patients with non-alcoholic fatty liver disease.

[0003] For example, the Chinese patent with publication number "CN210992801U" discloses a "medical fat liver patient exercise equipment", the main structure of which includes an H-shaped base composed of a pair of longitudinal steel pipes and a transverse steel pipe, a "herringbone" frame is fixed on the base, the frame includes a front fork and a rear fork, a driving wheel disc is hinged between the fork arms of the rear fork, a driven wheel disc is hinged between the two fork arms of the front fork, and the driving wheel disc and the driven wheel disc are connected by a chain; grooves are formed on the circumferences of the driving wheel disc and the driven wheel disc, engagement teeth are provided on the groove faces, a threaded rod is fixed at the center of the driven wheel disc, the threaded rod extends out from both sides of the driven wheel disc with equal length, a circular baffle is symmetrically fixed on the threaded rods on both sides of the driven wheel disc, a counterweight disc is threadedly connected to the outer side of the circular baffle, and a tightening nut is threadedly connected to the outer side of the counterweight disc. The pedaling resistance of the equipment can be adjusted, and the resistance can be increased or decreased to adapt to fat liver patients of different physical conditions or different stages, and the increase in resistance can increase the exercise amount of the patient and improve the exercise effect of the patient.

[0004] Obviously, the overall volume of the above-mentioned medical fat liver patient exercise equipment is relatively large, resulting in a large floor area and indoor space occupation, and the exercise resistance is provided by increasing the counterweight disc. Since the heavy counterweight disc will cause the foot pedal disc to continue to rotate when the exerciser stops driving, this rotation can easily cause the exerciser's legs to speed up and disengage, which can cause minor injuries to the exerciser or even serious injuries.
