A procedure to check for obstructed fallopian tubes. Carbon dioxide is inserted into the uterus to determine whether it passes into the abdomen.
A test to see if the Fallopian tubes are free from obstruction [After Isador Clinton Rubin (b. 1883), US gynaecologist].
Test that determines the patency of the fallopian tubes, used to help determine the cause of infertility. Carbon dioxide gas is introduced into the tubes through a cannula inserted in the cervix and attached to a manometer (device for measuring pressure in a gas). Increases in pressure shown on the manometer indicate that the tubes are blocked and the gas cannot escape into the abdominal cavity; a drop in pressure indicates open tubes.
