The present invention relates to an orthotic insole for preventing and treating foot disease and weight load imbalance due to various causes, and to a foot pressure measuring device and foot pressure measuring method serving as basic data for insole manufacturing. Is an orthodontic insole that adjusts the pressure according to a specific person's foot based on the method of measuring the foot pressure by the pressure change of the air bag provided in the insole, It relates to a foot pressure measuring device and a foot pressure measuring method.

In general, foot correction insoles are caused by structural abnormalities of the feet, such as flat feet and ankles, weight loads such as varus valgus, plantar fasciitis and hammer foot, foot movements caused by excessive exercise, narrow shoes, prevention of foot necrosis due to diabetes, and knee It is used to relieve the load imbalance caused by arthritis, and to shape the insole surface in consideration of the shape and disease of a specific person or to protect the lesion site by applying a pad, etc. Correct it so that the disease can be treated and prevented.

In order to manufacture such foot insoles, the process of measuring the weight load pressure distributed over a particular person's foot, that is, the foot pressure, is preceded. This is the result of most foot diseases. This is because the pressure distribution results in a pressure bias on a specific site, unlike the pressure distribution. Ordinary foot pressure measurement is a method of taking the sole contact surface on the paper using ink, or a method of measuring the pressure of the unit area sequentially with a measuring device in which a plurality of pressure sensors are arranged, the measurement result is shown in FIG. As in the foot pressure measurement example, the color of the unit area pressure is displayed as a mosaic graph.

However, these measurement results are obtained on a flat plate without shoes, and even if the insole for the correction is produced based on the measurement results, there is a problem that the pressure applied to the foot according to the particular wearing shoes differs from the correction expectations.

In addition, the manufacturing of orthodontic insoles is made through various processes, such as making a foot shape that imitates the feet of a specific person and molding the pattern considering the foot pressure with the insole material, in addition to measuring the upper foot pressure. The foot pressure corrected for a particular person's foot is changed over time due to the wear of a shoe, the shape change, etc. used by inserting an orthodontic insole, and the correction effect is remarkably decreased. The insole has a problem that there is no means to correct the pressure correspondingly.

The present invention, unlike the conventional foot pressure measurement method as described above allows the foot pressure measurement in the state of wearing shoes, so that the specific foot pressure measurement value that requires correction is the same condition as in the state after applying the insole for calibration To provide measurement and calibration methods.

To this end, a plurality of air bags are formed in the insole for calibration, and tubes connected to each air bag extend to a measuring device equipped with a pressure pump and an air pressure sensor to measure the air pressure change according to the weight load pressure applied to a specific foot. Characterized in that.

Based on the measured air pressure change value, the pressure of each air bag is added or subtracted to change the height of each air bag.

In addition, the tube connecting the calibration insole and the measuring device is easy to detachable, characterized in that the foot pressure correction by reattach the connecting tube even after a certain time after the measurement / calibration operation.
