The present invention also provides the method for using of a kind of above-mentioned forearm and palmar hand orthopaedics external fixation system, may further comprise the steps:
PPG mixture and modified isocyanate are mixed by 1: 0.6~0.75 mass ratio; Make polyurethane slurry after stirring; With the polyurethane slurry of 140~310 grams pour in the inner chamber of die cavity sheet pusher even, launch, then it directly is wrapped in the forearm and the palm place plastotype of human body.
The method for using of above-mentioned forearm and palmar hand orthopaedics external fixation system, wherein, the polyurethane slurry in the said inner chamber of pouring the die cavity sheet into is 140~175,250~310 grams.
Forearm of the present invention and palmar hand orthopaedics external fixation system; Temperature is controlled at 39 ℃ during plastotype; Avoided some patient because of overheated cardio-cerebrovascular diseases or the skin burn of bringing out; Make and handle the external fixation case and become convenient, simple,, the situation of skin allergy can not occur because die cavity is processed by the material that does not change body surface bio electricity potential difference and have a retractility.
Description of drawings
Fig. 1 is the structural representation of forearm of the present invention and palmar hand orthopaedics external fixation system;
Fig. 2 is a schematic partial cross-sectional view among Fig. 1;
Fig. 3 is the sketch map that forearm of the present invention and palmar hand orthopaedics external fixation system are wrapped in human body forearm and palm place.
The specific embodiment
Participate in Fig. 1 to Fig. 3; Forearm of the present invention and palmar hand orthopaedics external fixation system comprise die cavity sheet 1 with inner chamber and the polyurethane 12 that places this die cavity sheet 1 inner chamber; Two sides of die cavity sheet 1 are joined together to form the sheath shape through connecting device 11, and anterior being provided with hold the opening that thumb stretches out, with forearm and the palm place that directly is wrapped in human body; Connecting device 11 is a slide fastener, also can be tearing button (not drawing among the figure); Polyurethane 12 is mixed by 1: 0.6~0.75 mass ratio by PPG mixture and modified isocyanate; The quality of said polyurethane 12 is 140~310 grams; According to human bodily form's size, large size need be used 250~310 gram polyurethane, the small size need with 140~175 gram polyurethane.Wherein, Die cavity sheet 1 is processed by the flexible material that does not change the body surface potential difference and have a retractility; Like the knitted fabric (like cotton 70%, corn fiber 30%) of pure cotton knitted fabric or cotton and the multiple ratio blending of corn fiber or the linen-cotton knitted fabric of cotton and numb multiple ratio blending (as cotton 70%, numb 30%), this material retractility can reach 15%.
PPG mixture and the modified isocyanate mass ratio by 1: 0.6 is mixed, make polyurethane slurry after stirring, according to the size of body shaped; Large size need be used 250~310 gram polyurethane slurries; The small size need with 140~175 gram polyurethane slurries, the polyurethane slurry of appropriate amount is poured in the inner chamber of die cavity sheet after, use specific purpose tool--decide thick cylinder it pushed away even, expansion; Polyurethane slurry gets into solid-state softening section by liquid state; Be wrapped in forearm and the palm place of human body with the die cavity sheet this moment, behind the zip up (or buckling the tearing button), cooperates by hand that the retractility of die cavity self is moulding to make it fit in forearm and palm; After the patient injury kept motionless some minutes, die cavity hardened into voluntarily and rigidly fixes cover.
