Osmotic dilator
Osmotic Dilator
Osmotic dilator (pronunciation: /ɒzˈmɒtɪk daɪˈleɪtər/) is a medical device used in the field of Obstetrics and Gynecology.
Etymology
The term 'osmotic' is derived from the Greek word 'osmos', meaning 'push', and 'dilator' comes from the Latin word 'dilatare', which means 'to expand'.
Definition
An osmotic dilator is a small, rod-like device that is inserted into the cervix to induce dilation. It works by absorbing fluid from the surrounding tissues, causing it to swell and gradually expand the cervix. This is a common procedure used in abortions, miscarriage management, and to prepare the cervix for gynecological surgery.
Types
There are two main types of osmotic dilators: Laminaria and Dilapan-S. Laminaria is a type of seaweed that naturally absorbs water and expands. Dilapan-S is a synthetic dilator made from a hydrophilic polymer.
