Description

Machine for measuring six-minute walk test

Technical Field

The invention relates to the technical field of medical instruments, in particular to a machine for measuring a six-minute walking test.

Background

The heart rate refers to the number of heartbeats per minute of a normal person in a quiet state, also called a quiet heart rate, and is generally 60-100 times/minute, and individual differences can be generated due to age, gender or other physiological factors. Generally, the smaller the age, the faster the heart rate, the slower the elderly than the young, and the faster the heart rate in women than in men of the same age, are normal physiological phenomena. In a quiet state, the normal heart rate of an adult is 60-100 times/min, and the ideal heart rate is 55-70 times/min (the heart rate of an athlete is slower than that of a common adult and is about 50 times/min generally);

the pulse is an artery pulse which can be touched on the surface of a human body. The circulatory system of the human body is composed of the heart, blood vessels and blood and is responsible for the transportation of oxygen, carbon dioxide, nutrients and wastes. The blood is squeezed into the aorta by the contraction of the left ventricle of the heart and then delivered to the systemic arteries. The artery is a conduit formed by connective tissues and muscles with high elasticity. When a large amount of blood enters the artery, the pressure of the artery increases and the caliber expands, so that the artery feels the expansion at a shallow body surface, namely the pulse.

The pulse and heartbeat of a normal person are consistent. The normal adult is 60-100 times per minute, usually 70-80 times per minute, and the average is about 72 times per minute. The elderly are slow, 55-60 times per minute. The frequency of the pulse is influenced by age and gender, the fetus is 110-160 times per minute, the baby is 120-140 times per minute, the infant is 90-100 times per minute, and the child in the school age is 80-90 times per minute.

The health condition of a person can be evaluated from the changes of heart rate, pulse, oxygen saturation and blood pressure, in order to obtain more accurate data, the changes of heart rate, pulse, oxygen saturation and blood pressure in the six-minute walking process are generally measured to be used as the basis for evaluating the health, but in the prior art, when a six-minute walking test is carried out, a user is required to carry a plurality of devices to complete the test, and a great burden is brought to the user.
