Problems solved by technology

[0002] The existing protective gear used for rehabilitation treatment and sports protection generally has the following defects: a. The protective equipment does not fully fit the wearing part, which affects the appearance and comfort of use; b. Usually elastic materials are used to cover the wearing part. Although it fits perfectly, the excessive elasticity will give the human body a sense of tension and affect the comfort; c. Affected by the human body structure of the wearing part, it is difficult to wear and affects the convenience of use
Among them, the dual shape memory can only memorize a single temporary shape, and can be attached to the wearing part of the human body, but it is difficult to remove. For example, the publication number is CN104939959B

Embodiment 1

[0101] Example 1 - Preparation and use of smart wristband

[0102] The smart wristband described in Example 1 is a crystalline cross-linked trans-isoprene rubber-paraffin composite shape memory polymer, wherein the crystallization temperature of trans-isoprene rubber is 16°C, and the crystallization temperature of paraffin wax is 52°C. In this Example 1, it was prepared by melt blending molding vulcanization, and the proportion of components was calculated in parts by weight. Specifically, 100 parts of trans isoprene rubber particles were placed in an internal mixer at 75°C for stirring, and then sequentially Add 2 parts of stearic acid, 5 parts of nano zinc oxide, 2 parts of accelerator CZ, 60 parts of paraffin, two parts of anti-aging agent 4010NA and 1 part of sulfur, and finally mold it on a flat vulcanizer at 150°C to obtain a sheet shape memory material .

[0103] Then, the sheet shape memory material is processed as follows to obtain a wristband: the sheet shape memory...

Embodiment 2

[0105] Embodiment 2 - preparation and use of intelligent elbow support

[0106] The smart elbow support described in Example 2 is a crystalline crosslinked natural rubber-rice bran wax composite shape memory polymer, wherein the crystallization temperature of natural rubber is 8°C, and the crystallization temperature of rice bran wax is 55°C.

[0107] In this example 2, it was prepared by melt blending molding vulcanization, and the proportion of components was calculated in parts by weight. Specifically, 100 parts of natural rubber particles were put into an open mill at 60°C and stirred, and then 4 parts of stearin were added in sequence Acid, 2 parts of nano-zinc oxide, 1 part of accelerator M, 50 parts of rice bran wax, 10 parts of carbon black, 1 part of anti-aging agent D, 1 part of sulfur, and finally molded on a flat vulcanizer at 142 ° C to obtain a sheet shape memory Material.

[0108] Then the sheet shape memory material is processed as follows to obtain elbow pads...

Embodiment 3

[0110] Example 3 - Preparation and use of smart leg guards

[0111] The leg guard described in Example 3 is a crystalline crosslinked polyethylene-octene copolymer-glyceryl monostearate composite shape memory polymer, wherein the crystallization temperature of the polyethylene-olefin copolymer is 13°C, and monostearic acid The crystallization temperature of glycerides is 61°C.

[0112] At 80° C., the leg guard of Example 3 is a thin layer that is fully unfolded and flattened. Stress is applied to bend it into a hollow concentric cylinder with a diameter of 7 cm, and then fixed at 37° C. for 25 minutes. Stress was applied at 37°C to expand it into a 3 / 5 round hollow cylinder with a radius of 7cm, and then fixed at 0°C for 10 minutes. Put the shin guard on the outside of the leg, and through the heating of human skin, the shin guard can shrink and fit the body intelligently, which is beautiful and comfortable. Use a hot towel at 65°C for no more than 1.5 minutes to remove the ...

Abstract

The invention relates to a rehabilitation treatment / sports protection tool. The rehabilitation treatment / sports protection tool is of a sheet shape, a cylindrical shape or a cylindrical shape with anopening and is prepared by a shape memory material, the shape memory material comprises crystalline crosslinking polymer and crystalline low-molecular-weight organic matter, the crystal melting temperature of the crystalline crosslinking polymer is lower than human body temperature, the crystal melting temperature of the crystalline low-molecular-weight organic matter is higher than the human bodytemperature, and the difference between the crystal melting temperature of the crystalline crosslinking polymer and the crystal melting temperature of the crystalline low-molecular-weight organic matter is not lower than 30 DEG C. When the rehabilitation treatment / sports protection tool is applied to a human body, the rehabilitation treatment / sports protection tool can intelligently fits the human body and easily fall off from the human body after being used. After the rehabilitation treatment / sports protection tool is used, the rehabilitation treatment / sports protection tool can be reappliedto the original position after being sterilized and reprogrammed.

Description

technical field [0001] The present invention relates to the field of rehabilitation treatment / sports protective equipment, in particular to a rehabilitation treatment and sports protection equipment that can be attached to the body and is easy to fall off. Specifically, it relates to a rehabilitation treatment / sports protection equipment and its preparation method and use method. Background technique [0002] The existing protective gear used for rehabilitation treatment and sports protection generally has the following defects: a. The protective equipment does not fully fit the wearing part, which affects the appearance and comfort of use; b. Usually elastic materials are used to cover the wearing part. Although it fits perfectly, the excessive elasticity gives the human body a sense of tension and affects comfort; c, affected by the human body structure of the wearing part, it is difficult to wear and affects the convenience of use. [0003] The shape memory material is a ...
