Embodiment 1

[0019] Mix the polyether polyol mixture and the modified isocyanate at a mass ratio of 1:0.6, and stir evenly to obtain a polyurethane slurry. According to the size of the human body, 410-510 grams of polyurethane slurry is required for a large size, and 410-510 grams of polyurethane slurry for a small size. 250 ~ 310 grams of polyurethane slurry, after pouring a suitable amount of polyurethane slurry into the inner cavity of the arm and palm cavity, use a special tool - a thickness-setting roller to push it evenly and spread it, and the polyurethane slurry changes from liquid to solid Softening section, at this time, wrap the arm-to-palm cavity around the arm and palm of the human body, zip it up (or buckle the tear-off button), and use manual matching with the elastic shape of the cavity itself to make it fit on the arm And the palm, the patient's injured part remains still for several minutes, and the cavity hardens itself into a rigid set.

Embodiment 2

[0021] The polyether polyol mixture and the modified isocyanate were mixed at a mass ratio of 1:0.62, and the rest of the steps were the same as in Example 1.

Embodiment 3

[0023] The polyether polyol mixture and the modified isocyanate were mixed at a mass ratio of 1:0.65, and the rest of the steps were the same as in Example 1.

Abstract

The invention relates to an arm and palm orthopaedics external fixing system, which is directly covered on the arm and palm part of a human body and comprises an arm and palm connecting die cavity and polyurethane, wherein the arm and palm connecting die cavity is provided with an inner cavity, and the polyurethane is placed in the inner cavity of the arm and palm connecting die cavity. The invention also relates to a use method of the arm and palm orthopaedics external fixing system. The arm and palm orthopaedics external fixing system provided by the invention has the advantages that the temperature is controlled at 39 DEG C during the shaping, and the skin burnt or disease causing, such as cardiovascular diseases and the like on some patients caused by too high temperature can be avoided, so the external fixing case treatment becomes convenient, fast and simple, and because the die cavity is made of telescopic materials which cannot change the body surface bioelectric potential difference, and the skin allergy condition cannot occur.

Description

technical field [0001] The invention relates to the field of orthopedic external fixation, in particular to an arm and palm orthopedic external fixation system and a use method thereof. Background technique [0002] In the invention patent application with the publication number CN101906202A titled "Polyurethane for orthopedic external fixation system in complex environment and its preparation method", a polyurethane for orthopedic external fixation system is disclosed. The alcohol mixture and the modified isocyanate are prepared by reacting at a weight ratio of 1:0.6-0.75. The polyurethane is used in conjunction with the mold cavity, which can handle complex parts that are difficult to fix with gypsum. It has sufficient rigidity and strength, and can penetrate X Rays can clearly understand the healing of the fracture site; at the same time, it is easy to breathe and clean, and the medical staff can freely remove it according to the needs of the patient to clean and treat th...
