Medical exercise treadmill with adjustable gradient

Abstract

The invention relates to the field of medical diagnosis instruments, and particularly relates to a medical exercise treadmill with an adjustable gradient. The medical exercise treadmill comprises a walking table and a pedestal, wherein the front end of the walking table is hinged to the pedestal; a lifting device is arranged between the rear end of the walking table and the pedestal; a positioningmechanism used for limiting a plurality of specific gradient positions of the walking table is arranged in the lifting device; the lifting device comprises a first rotation shaft rotationally arranged on the pedestal, two cams respectively matched and installed at two ends of the first rotation shaft, and two idler wheels respectively rotationally arranged on two sides of the walking table; the first rotation shaft is distributed along the width direction of the pedestal, so that the edges of the idle wheel and the cam on the corresponding side can be mutually contacted and matched in a rolling manner; and a worm gear reducer used for driving the first rotation shaft to rotate via a drive handwheel is also arranged at the position, at one end of the first rotation shaft, on the pedestal.The medical exercise treadmill with the adjustable gradient is accurate and continuous in gradient adjustment, and thus a subject can truly reflect the own condition via a standard exercise scheme.

Description

technical field [0001] The invention relates to the field of medical diagnostic equipment, in particular to a medical sports board with adjustable gradient. Background technique [0002] In the examination and diagnosis of coronary heart disease in the Department of Cardiology, although the maximum reserve capacity of coronary artery expansion has declined in many patients with coronary heart disease, usually the coronary blood flow can still maintain normal at rest, without myocardial ischemia, and the electrocardiogram can be completely normal. In order to reveal the reduced or relatively fixed coronary blood flow, exercise or other methods can be used to load the heart, increase myocardial oxygen consumption, induce myocardial ischemia, and assist clinical diagnosis of myocardial ischemia. This kind of test method that induces myocardial ischemia by increasing the heart load through exercise, resulting in ischemic ECG changes, is called electrogram exercise test, and the ...

AI Technical Summary

Problems solved by technology

The continuity is poor, and the continuous load increase of the subject cannot be realized, so it cannot truly reflect the condition of the subject

Most of the automatic adjustment methods rely on the cylinder to achieve. Although the continuity is good, the subject can realize the slope adjustment without stepping off the walking platform. However, under the continuous stepping of the subject, the expansion and contraction accuracy of the cylinder piston rod is difficult to guarantee. Precise adjustment of incline in ECG exercise testing against implementation of cardiac load increase protocol
