It is different according to the different pelvis size of human body, so paraboloid can be at various height on (be higher or lower than pubis)
The pressure from ventral direction is reflected, if this paraboloid there are enough sizes to reflect the pressure of abdomen, pelvic cavity
Organ will be in pelvic cavity on right position,, will be straight when ventral direction carrys out pressure if this paraboloid is too short
Connecing causes pelvic organ to run down and (prolapse).The analysis of this pelvis bottom parabolic reflector pressure to normal configuration
The case where being equally applicable to when pelvis bottom is defective using pessary: pessary can be repaired or to improve this paraboloidal
Structure is gone baroreflex on being correctly oriented with this.
It is existing study have shown the not urinary incontinence female bladder bottom and urethra joint have a curved structure
And thering is the women of the urinary incontinence not have, this shows there is vital effect for control urine at this complications, i.e., when compression of urethra folds
When, it is folded to itself to prevent leakage of urine, and can generate bigger linear outer impulse force when bladder is full.According to above
Research theory, pessary is designed as enabling the warp architecture at this complications of support by we, and it is mentioned in intravaginal
