Embodiment Construction

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

[0021] The invention discloses a rigid shaping process for human pelvis, the rigid shaping process is completed through the pelvic cavity, such as figure 1 As shown, the pelvic cavity is in the shape of shorts, including front and rear two-valve cavity 1 with the same structure, and zippers 2 are provided on both sides of each valve-shaped cavity 1, and each valve-shaped cavity 1 is located on the inner thigh There is a tear button 3, and the rigid molding process of the present invention comprises 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 28-29 seconds, fully mix well and evenly react to prepare Obtain polyurethane slurry;

[0023] S2: Pour the polyurethane slurry into one valve-shaped cavity 1 first, an...

Abstract

The invention discloses a rigid moulding technology for a human body pelvis. The technology comprises the steps that polyurethane slurry is poured into a mould cavity under stirring, the polyurethane slurry in the mould cavity is fully laid and pushed to be uniform, the pelvis of a moulded person is sleeved with the mould cavity, and lastly moulding is conducted. According to the rigid moulding technology for the human body pelvis, quick and accurate standardized moulding of the human body pelvis is achieved, operation is easy and convenient, and popularization is easy.

Description

technical field [0001] The invention relates to a shaping process, in particular to a rigid shaping process for human pelvis. 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. [0003] Disclosed in the description of Chinese patent CN203042559U is a molding process for the abdomen and legs: the polyether polyol mixture and the modified isocyanate are mixed in a mass ratio of 1: 0.6 to 0.7...
