A double probe is a medical device intended for medical use. It is used to insert into the patient's stomach and intestines, allowing various tests to be carried out, as well as the removal of various objects from the stomach or intestines. One end of the probe is shaped like a funnel, which allows it to easily penetrate the stomach cavity through the mouth or nose, while the other end has a more complex shape, which allows it to be immersed in the intestines. A double probe is a two-probe device that has one or two channels to study the contents of the organ. Sometimes the double probe zone is equipped with an additional channel for washing the organ cavity with warm water.
