LEITAT 1 is the first medically validated and industrially producible 3D emergency ventilator. The device can be produced at industrial scale and can reach a daily production capacity of 50 up to 100 units. The ventilator has been designed by Leitat and medically validated by Hospital Parc Taulí (Spain). The LEITAT 1 mechanical ventilation system is a device designed to keep in vital support the patient in a situation of severe respiratory failure who requires intubation and invasive mechanical ventilation. It should not be considered as a partial ventilatory support system (non-invasive mechanical ventilation – NIMV) in patients who ventilate spontaneously. It is not a therapy, it is a support intervention, a medical device for ventilatory and temporary support therapy that ventilates the patient while correcting the originating problem. The device as a whole allows to apply a mandatory ventilation mode with a programmable volume to a patient through the mechanical actuation of a conventional resuscitation balloon system (AMBU). This equipment is used in the context of a clinical study approved by the Spanish Agency of Medicines and Medical Devices (AEMPS). The device as a whole allows a regulated amount of air/min to be delivered in a mandatory ventilation mode to a patient by means of the mechanical activation of a conventional AMBU system.
