Uterine dilators of Hegar type, from diameters 4 mm (right) to 17 mm (left). These sounds are intended for probing a woman's uterus through the cervix, to measure the length and direction of the cervical canal and uterus. Dilators are primarily used to open and dilate the cervix to gain access to the uterine cavity, but can also be used as sounds.
Over time, the osmotic dilator absorbs fluid and swells to 3-4 times the initial diameter. [9] Most of the increase in size occurs within 6 hours after the dilator are placed in the cervix, though further expansion will continue over 12–24 hours. [7] The number of osmotic dilators placed depends on the degree of cervical dilation that is sought.
A set of Hegar dilators, from Hegar 4 to 17 (right to left) Hegar dilators are dilators used to treat vaginismus and induce cervical dilation, and for inflatable penile implant procedures, though for penile implants it has been shown that outcomes are better without dilation. [1] [2] [3] [4]
The relationship between dilation and internal friction is typically illustrated by the sawtooth model of dilatancy where the angle of dilation is analogous to the angle made by the teeth to the horizontal. Such a model can be used to infer that the observed friction angle is equal to the dilation angle plus the friction angle for zero dilation.
Dilation is commutative, also given by = =. If B has a center on the origin, then the dilation of A by B can be understood as the locus of the points covered by B when the center of B moves inside A. The dilation of a square of size 10, centered at the origin, by a disk of radius 2, also centered at the origin, is a square of side 14, with ...
Spinach helps dilate blood vessels, which can increase blood flow to the genitals. Other greens like kale, cabbage, and bok choy are good sources of folate, which helps reproductive health.
The opening of the dark-blue square by a disk, resulting in the light-blue square with round corners. In mathematical morphology, opening is the dilation of the erosion of a set A by a structuring element B:
A shape (in blue) and its morphological dilation (in green) and erosion (in yellow) by a diamond-shaped structuring element. Mathematical morphology (MM) is a theory and technique for the analysis and processing of geometrical structures, based on set theory, lattice theory, topology, and random functions.
