To inhibit virus infection, the current technical solutions adopted in hospital wards for lung ventilation mainly consist of personal and methodical protections aimed at avoiding the infection generated in the intensive care units. The present work wishes to give, as far as possible, useful solutions to prevent potential contagion conditions from being generated in hospital settings.

The aspiration of the gases exhaled by the patients and their evacuation outside and far from the hospital ward has the main function of reducing the possibility of contagion in the ward.

The aspiration of ambient air around the patient station, claimed in claim 8, further reduces this danger.

With reference to claim 3, monitoring and setting of patient parameters and of the lung ventilation, carried out remotely in a control room, require less presence of doctors and nurses in the hospitalization ward.

Doctors and nurses move less, waste less time, create less confusion in the hospital ward, expose themselves less to the danger of contagion, a part of them, or in any case for a part of time, they must not wear bulky protections which, at the very least, make you waste precious time.

Ultimately the patients are better controlled and better cared, the operators are better protected from the infection, they are less stressed and worried and they can devote more time and energy to the control of the lung ventilation of the patients and therefore to save more human lives.

It is better to intervene actively, setting the environment rationally, so that there is no danger of contagion, than not to leave the burden of avoiding contagion to passive protection alone. This does not mean not to use masks, gowns, gloves, screens and other protective devices, on the contrary, but to create conditions in which they are more effective and safe.

The compressors (4) and the aspirators) 9) are arranged outside the department according to the logic shown above.

Gas-related processes, potentially dangerous for contagion, are moved outside the operational departments, to confined and inaccessible places.

The distribution networks (3) of respirable gases and the intake network (8) of exhaled gases should also be as external as possible to the departments.

The external stations of aspirators and compressors that serve the networks are efficient, the pneumatic machines as a whole can be generously sized and in adequate numbers to overcome emergencies and failures, the energy for their operation can be guaranteed by emergency generators and uninterruptible power supplies.

The hospital control units (1), almost devoid of pneumatic functions and containing only the most noble functions, can thus have small and handy dimensions. They control the vital parameters of the individual patient, they control all the parameters relating to the patient's lung ventilation activity and manage their operations.

With reference to claims 4 and 5, since in certain circumstances it may be necessary to move the position of the bed within the ward, high and long connections facilitate movement and the double connection guarantees the supply and aspiration of gas even during movement .

With reference to claim 7, the possibility of setting up ships, railway wagons, planes with hospital wards and pulmonary ventilation systems that can be easily assembled and disassembled could be a solution, not only for current contingencies, but for a long-term strategic one.

This work which basically, to a limited extent and in a particular area, seeks to rationalize the pulmonary ventilation department to decrease the danger of contagion, is mainly dedicated to doctors and healthcare personnel who in these days heroically works to treat a huge number of patients.

Such a structured department, with the centralization of some fundamental pneumatic functions, is also more economical than the current structures with the current pulmonary ventilation machines.

The present work was originally integrated with another patent which concerns the operating principle of a new pulmonary ventilator. As said, this was quickly listed and deposited due to the current pandemic situation, also for this reason it is devoid of drawings, which are perhaps not essential.
