Embodiment Construction

[0021] Such as figure 1 , figure 2 , Figure 4 As shown, an insole that adapts to the shape of the sole of a pregnant woman includes an insole body, a pressure sensor 4 and a small integrated electronic device 5. The insole body is from top to bottom an insole top layer 1, an insole middle layer 2 and an insole bottom layer 3; The insole middle layer 2 is a closed cavity structure, which is molded by non-toxic flexible rubber; the upper surface of the insole middle layer 2 is a curved surface adapted to the shape of the human foot, and the lower surface of the insole middle layer 2 is a plane , several tie bars 21 are uniformly arranged between the upper surface and the lower surface; by test and finite element analysis, the tie bars 21 are set in a cylindrical structure with high strength, and the diameter of the tie bars 21 is between 3-5mm, and the distance between adjacent tie bars 21 is changed between 15-30mm. The purpose of setting the tie bars is to increase the re...

Abstract

The invention discloses an insole self-adapting the pelma shape of a pregnant woman. The insole comprises an insole body, a pressure sensor and a small integrated electronic device; the insole body comprises an insole top layer, an insole middle layer and an insole bottom layer from top to bottom; the insole middle layer is of a closed cavity structure and formed by pressing non-toxic flexible rubber mold; the closed cavity of the insole middle layer is filled with high viscosity liquid; the pressure sensor and the small integrated electronic device are installed on the upper surface of the insole middle layer, and the pressure sensor is combined with a signal processing module and a Bluetooth module to form a complete plantar pressure distribution monitoring system. By applying the system, the pregnant women can understand the plantar pressure changes in different periods of gestation and under different moving postures; according to the obtained pressure values, viscosity and dosageof liquid in the closed cavity of the insole middle layer are scientifically adjusted, and the cavity has the good elastic buffer capacity and reset capacity.

Description

technical field [0001] The invention relates to a foot health care product, in particular to an insole adapting to the shape of the sole of a pregnant woman. Background technique [0002] With the increase of pregnant women's gestational age, the pressure value at the maximum pressure part of the foot (the third metatarsal bone and the second metatarsal bone) gradually increases when walking, indicating that these parts are the main impact load bearing parts, that is, pregnant women The middle part of the forefoot is prone to fatigue and damage when walking; in addition, the arch of the foot will also increase with gestational age, and the reduction of the height of the arch of the foot will lead to diseases such as plantar fasciitis, knee joint pain and low back pain. Therefore, choosing comfortable insoles is very important for pregnant women. However, the insoles on the market are not designed according to the changes in the feet of pregnant women during different pregna...
