Problems solved by technology

Because the splint fixation is easy to dislocate the fracture surface after reduction, resulting in deformity and functional defect of the fixed part; and plaster cast or polymer bandage cast is difficult to adjust the circumference of limbs before and after bone injury due to high difficulty in operation. Its poor air permeability and other problems are not conducive to doctors' timely examination and treatment of surface surgical trauma at the bone wound, etc.
If tube-type fixation is used, it is easy to cause joint adhesion and joint ankylosis, etc.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with examples.

[0021] The invention discloses a rigid molding process for the forearm of a human body, which is completed through a forearm cavity. The forearm cavity includes two left-right symmetrical and connected as one cavity. The rigid molding process of the present invention includes the following steps:

[0022] S1: Make the temperature of the raw material polyether polyol mixture and the modified isocyanate reach 20-25°C, then mix and stir them, the stirring speed is 1500 rpm, and the stirring time is 18-20 seconds, fully mix well and evenly react to prepare Obtain polyurethane slurry;

[0023] S2: Pour the polyurethane slurry into one cavity first, and when the cavity of the cavity is half filled, keep pouring and start pouring polyurethane slurry into the cavity of the other cavity after 3 seconds, so that the two The polyurethane slurry content and reaction degree of the cavity tend to b...

Abstract

The invention discloses a rigid molding technology for a forearm of a human body. The technology comprises the steps of stirring polyurethane paste, pouring the polyurethane paste into a cavity, paving the cavity with the polyurethane paste which is pushed to be uniform, sleeving the forearm or palm of a molded person with the cavity, and finally performing molding. The rigid molding technology for the forearm of the human body achieves rapid, accurate and standard molding of the forearm of the human body, and is easy and convenient to popularize and easy to popularize.

Description

technical field [0001] The invention relates to a shaping process, in particular to a rigid shaping process for the forearm of a human body. Background technique [0002] The traditional non-surgical external fixation that has continued to this day mostly uses plaster bandage casts, polymer bandage casts or splints for fixation. Because the splint fixation is easy to dislocate the fracture surface after reduction, resulting in deformity and functional defect of the fixed part; and plaster cast or polymer bandage cast is difficult to adjust the circumference of limbs before and after bone injury due to high difficulty in operation. Poor air permeability and other problems are not conducive to doctors' timely examination and treatment of surface surgical trauma at bone injuries. If tube-type fixation is used, it is easy to cause joint adhesion and joint ankylosis. [0003] Chinese patent CN203060004U discloses a forearm cavity for external fixation in orthopedics. The cavity...
