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 whole arm of a human body, which is completed through a full-arm cavity. The full-arm 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 23-24 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 the polyurethane slurry into the cavity of the other after 4 seconds, so that the two The polyurethane slurry content and reaction degree of the cavity tend to...

Abstract

The invention discloses rigid modeling technology used for whole arms of a human body. The rigid modeling technology comprises following steps: stirring polyurethane slurries; pouring polyurethane slurries into a mold cavity; overspreading and uniformly pushing polyurethane slurries in the mold cavity; sleeving the mold cavity to whole arms and palms on the single side of a modeled person; and finally performing modeling.The rigid modeling technology used for whole arms of the human body has following beneficial effects: standardized modeling of whole arms of the human body can be rapidly and accurately achieved; operation is carried out easily and conveniently; and the rigid modeling technology is easily prompted.

Description

technical field [0001] The invention relates to a shaping process, in particular to a rigid shaping process for the whole arm 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 CN203042561U discloses a whole arm with palm cavity for external fixation in orthopedi...
