COUGHING AID DEVICE
First Claim
1. Coughing aid apparatus comprising:
- a) a first subassembly comprising;
a ventilation unit provided with a turbine and an air control unit provided with means enabling connection of the aforementioned ventilation unit with the patient in inflow as well as outflow and a means, of the regulation solenoid valve type, adapted to produce series of pulsations of air, positive pulsations during the inspiration phase and negative pulsations during the expiration phase;
an electronic unit adapted to control the aforementioned ventilation unit and the aforementioned air control unit;
b) a second subassembly comprising a mask, an antibacterial filter and a distribution tube connected to the first assembly;
characterized in that the electronic unit, is constituted;
a) by a storage memory for preset programs corresponding to expectoration type profiles by type of disease and patient profile;
b) by a microcontroller that operates the ventilation unit and the air control unit;
first, by means of preset programs contained in the aforementioned storage memory, so as to generate a pressure, positive during the inspiration phase (IP) and negative during the expiration phase (EP), whose values of flow rate and pressure and the number and duration of inspiration and expiration cycles are configurable;
second, by means of a flow rate sensor and a pressure sensor that measure, in real time, the flow rate and the pressure in order to compare them to prerecorded limit values for inspiratory and expiratory volumes, pressure, and flow rate and act immediately on the velocity of the turbine of the ventilation unit and on the means for regulation of the air control unit.

Abstract
The invention relates to a coughing aid device, comprising a first-sub-assembly (1) with a ventilation group (11), an air control unit (12) and an electronic management device (13) and a second sub-assembly (2) with a mask (21), an antibacterial filter (22) and a distribution tube (23) connected to the first assembly (1). Said device is essentially characterised in that the electronic device (13) is made up of a) a storage memory for preset programmes corresponding to expectoration types by pathology type and patient profile, b) a microcontroller operating the ventilation group (11) and the air control unit (12), by means of the preset programmes contained in said storage memory, a flow sensor (16) and a pressure sensor (17) which measure the flow and pressure in real time in order to compare the same with prerecorded flow, pressure and inhaled and exhaled volume limit values and to act immediately on the means for controlling the ventilation group (11) and the air control regulation unit (12).
