Balloon probe for studies of digestive motility (fecaloma simulated) characterized by being a hollow probe of variable length, although the most common will be approximately 30 cm. The probe is open to the outside by a hole in the tip (1) and by a cone that covers its entire circumference at the opposite end (7). Near the tip the probe is coupled with a distensible balloon that surrounds it (3) and that can be inflated thanks to a closed channel that runs adhered to the wall of the probe (4) and that ends in a connection system of the usually used for syringes (6). The balloon can be of different sizes according to the experiment to which it is directed, but the most usual size will be approximately 1 cm. Of diameter in inflation. Before and after the balloon, two holes (2) are made in which two 1 mm tubes open. Of diameter that run through the interior of the probe and that emerge near the final cone, to end up in a connection system of the usual systems for manometric studies (5). These tubes are perfused with distilled water and act as pressure sensors. (Machine-translation by Google Translate, not legally binding)
