The present invention describes a portable device for the automated monitoring of blood pressure using the Korotkoff technique, which consist in an inflatable mattress with elastic characteristics that is located about the arm of the user, which exerts a uniform pressure over all the points brought into contact with the arm upon being inflated the pressure, inflating and deflating speed are controlled by an air pump, this being carried out by connecting an elastic tube from the mattress to the body of the device where the air pump and the pressure sensor are housed. A sound sensor is adapted to the mattress and brought into contact with the brachial artery, which cables are coupled to the inflating tube, a set of electronic devices being arranged within the body of the device for capturing the signals generated by the sensors, amplifying and filtering the signals and pre-processing the same for being sent to an electronic microprocessor, this latter element processing said signals fo r extracting the information in a data form, then said data being combined for generating metrics, which are established as entries to the neural network, which results are interpreted by another algorithm which finally provides the result of the pressure measurement. The device displays the result in a screen and stores the data and results, along with an identifier of the patient and the date for the subsequent consultation, generation of a record or transference.La presente invención describe un dispositivo portátil para el monitoreo automatizado de la presión arterial utilizando la técnica de Korotkoff, que consiste en un colchón inflable con características elásticas que es colocado alrededor del brazo de una persona de manera que al inflarse se ejerza una presión uniforme sobre todos los puntos de contacto con el brazo, la presión, velocidad de inflado y desinflado se controla mediante una bomba de aire, lo cual puede realizarse conectando un tubo elástico desde el colchón hasta e
