AI Technical Summary

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

[0021] The present invention will be further described below in conjunction with examples.

[0022] The invention discloses a rigid molding process for human body with legs connected to the abdomen. The process is completed through a cavity with legs connected to the abdomen. Inventing the Rigid Shaping process includes the following steps:

[0023] 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 28-29 seconds, fully mix well and evenly react to prepare Obtain polyurethane slurry;

[0024] S2: Pour the polyurethane slurry into the cavity of one valve first, and when the cavity of the valve is half filled, keep pouring and start pouring polyurethane slurry into the cavity of the other valve after 4 seconds, so that both sides The polyurethane slurry content and reaction degree of the cavity tend to be balanced, and the single-valve ...

Abstract

The invention discloses a rigid modeling process used for abdomen-connected legs of a human body. The rigid modeling process comprises the following steps: stirring polyurethane slurry; filling the polyurethane slurry into a mold cavity; fully laying and uniformly spreading the polyurethane slurry in the mold cavity; sleeving an abdomen and whole legs of a body to be modeled with the mold cavity; finally, modeling. With the adoption of the rigid modeling process used for the abdomen-connected legs of the human body, disclosed by the invention, rapid and accurate standard modeling of the abdomen-connected legs of the human body is realized; the rigid modeling process is simple and convenient to operate and is easy to popularize.

Description

technical field [0001] The invention relates to a shaping process, in particular to a rigid shaping process for the abdomen and legs 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 CN203042559U discloses an abdomen-to-leg cavity for external fixation in orthop...
