Abstract

Pseudoauricular cannula, made of biomedical grade material, formed in one or more assembled pieces, hollow like a pipe and with a zone of elastic walls which are deformable and able to recover their natural shape, which serves as a cannula for entry of the devices which act as pumps, performing ventricular or cardiac function, in such a way that it presents an elastic zone which allows the collapse of its walls when a vacuum is produced, preventing negative pressures from reaching the patient's auricula and which, on recovery of its collapse position, is able to draw the blood from the patient's auricula to the pseudoauricula, the latter remaining completely full and available for supplying the pump.
