Description

recovery shoes

technical field

The utility model relates to the field of intelligent wearable equipment, in particular to a rehabilitation shoe.

Background technique

Statistics from the World Health Organization show that falls are the second leading cause of accidental or unintentional injury deaths around the world, with 424,000 people losing their lives each year.

According to the death cause monitoring data of the National Disease Surveillance System of the Ministry of Health of my country in 2011, falls occupy the first place in the cause of injury death of the elderly over 65 years old in my country.

Decreased static balance and gait dynamic stability are the main causes of falls in the elderly. At the same time, in order to compensate for the decline in their mobility, the elderly tend to take a more cautious and slow pace, resulting in shorter strides, discontinuous walking, and inability to lift their feet to a suitable height, which is more likely to cause falls.

In fact, neurological disorders, including neurodegeneration common in older adults, decreased proprioception, weakened muscle and joint strength, vestibular system disorders, and many other factors can lead to decreased balance. Among them, the central control ability of the elderly is reduced, the sense of contrast is reduced, the trunk swings larger, the reaction ability is reduced, and the reaction time is prolonged.

Human gait contains a lot of physiological information. When there is a problem with a certain organ or a certain part of human body movement control, it can often be directly reflected from the gait. Therefore, through continuous recording of gait data, professional rehabilitation institutions can make health suggestions to users, formulate exercise plans, improve physical functions, and avoid more serious health problems.

Based on the above reasons, the existing rehabilitation shoes designed for reading gait information for the elderly mainly detect the gait information of the human body by installing pressure sensors at different positions in the shoes. When the heel is lifted or landed successively, the values measured by the pressure sensors located on the toe and the heel will change accordingly, so as to realize the analysis of the walking gait of a person.

However, the above-mentioned rehabilitation shoes for reading gait information are equipped with pressure sensors in the shoes, which can only generate feedback after the soles of the feet are in contact with the soles. When some soles of the feet are separated from the soles, it is difficult to measure the changes of the soles of the feet.

detailed description

Below in conjunction with accompanying drawing and specific example, further illustrate the utility model, should be understood that these embodiments are only used for illustrating the utility model and are not intended to limit the scope of the utility model, after having read the utility model, those skilled in the art will understand the utility model Modifications of various equivalent forms of the novelty all fall within the scope defined by the appended claims of the present application.

As shown in Figure 1 and Figure 2, this embodiment discloses a rehabilitation shoe, including a shoe 1, a plurality of pressure sensors 2 are distributed on the bottom of the inner side of the shoe 1 and the upper of the inner side of the shoe 1, and are used for walking by patients or elderly people. During the process, the soles of the feet will generate pressure on each pressure sensor 2, and then read the wearer's gait information according to the size of the measurement data of each pressure sensor 2.

At the same time, a triaxial acceleration sensor 3 is installed on the heel of the shoe 1, and the triaxial acceleration sensor 3 can reflect the motion property and position of the heel relative to the ground during walking. Then, before the toes of a person leave the ground during walking, the three-axis acceleration sensor 3 reads the acceleration of the heel in three directions relative to the ground, so that it can identify whether the sole of the foot of the wearer will bend to one side during the process of lifting the foot, and then Judging the health status of the corresponding leg bones, or the wearer's center of gravity; after the toes are off the ground, the three-axis acceleration sensor 3 reads the acceleration of the entire suspended sole relative to the ground in three directions, so that it can identify the wearer when the sole is suspended in the air. From the back to the front of the landing, the swing direction of the soles of the feet can be used to identify whether the wearer has lameness problems such as long or short legs.

Specifically, the pressure sensor 2 of this embodiment is connected to the main control unit through the anti-malfunction unit, and the anti-maloperation unit compares the measurement data output by the pressure sensor 2 with a minimum threshold signal, and when the output of the pressure sensor 2 is greater than the minimum threshold After receiving the signal, the output of the pressure sensor 2 can be allowed to be sent to the main control unit. The main control unit receives the output of the pressure sensor 2, generates measurement data, and communicates the measurement data to the external terminal through the wireless communication unit, and the external terminal interprets the measurement data.

Then, in this embodiment, only when the output of the pressure sensor 2 is large enough, the main control unit can read the output of the pressure sensor 2, so as to prevent the wearer from twisting the sole of the foot and causing the pressure sensor 2 to measure erroneous data when the wearer is uncomfortable.

The main control unit of this embodiment includes a single-chip microcomputer, and when the output of the pressure sensor 2 is an analog quantity, an analog-to-digital converter is arranged between the switching element and the single-chip microcomputer, so that the single-chip microcomputer reads digital measurement data.
