The invention relates to an artificial anus obturating device. The device according to the invention includes a magnetic peri-orificial plate (3) provided on one of its surfaces with an adhesive coating (5), and a flexible plug lodgeable in the intestinal opening and essentially constituted by a hollow cylindrical body (6) provided at its end turned towards the outside of the abdomen with a magnetic ring (7) which surrounds it and, when said plug is in the intestinal opening, cooperates with the peri-orificial plate to obturate the artificial anus, the said cylindrical body including, at its opposite end turned towards the intestine, slots (12) for the passage of gases, the cavity of said cylindrical body being closed at its outer end by a suitable closure device provided with one or several slots (14) for the passage of gases.

Retractable feeler arms are disposed at uniform angular intervals around a central frame and elastically coupled to the frame for radial withdrawal or outward extension and displacement in a general movement of translation of the device. In the operating position, the tips of the feeler arms are maintained in contact with the cylindrical surface to be measured and differential measurements of the end positions of the feeler arms are taken by means of electrical detectors.

A multidetector is constituted by a lattice of N rods each having a ferromagnetic portion and slidably mounted within N coils forming the secondary windings of a transformer, each detector being constituted by a rod associated with a coil. The common primary circuit of the transformer is formed by a single coil which surrounds the N secondary windings and is supplied with alternating current of constant amplitude. The rods are brought into contact with an object for taking an impression of a portion of its external surface. The N voltages developed at the terminals of the N secondary coils are transmitted sequentially by a multiplexer to the screen of a storage oscilloscope so as to form the impression by means of N points, a coordinate of each point being a linear function of the voltage developed at the terminal of the corresponding secondary coil.

Device for taking an impression and visualizing said impression

The invention relates to a tactile pick-up for making contact with an object and emitting signals which are representative of the deformation caused by the object. The pick-up comprises a supple layer of variable electrical conductivity as a function of its state of compression, a matrix of measuring electrodes each connected to an output lead, and a large number of conducting elements connected to an electric source fixing their potential at a determined excitation value.
