Description
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.
