Description

DESCRIPTION

Germ protection system for schools and the like

Field of the invention

In systems for the prevention of infections by germs: viruses, bacteria and protozoa or parasites in schools.

State of the art

In schools, having an agglomeration of students in the classrooms and being a daily meeting of the mimes, there are countless infections due to the great promiscuity among students. Due to this circumstance and in case of epidemics, it is little less than impossible to keep them separate and with adequate protection, since masks have many drawbacks. This invention can be considered as a continuation of patent P202000080 by: Anti-germ protection system for vehicles, hospitals, restaurants, schools, elevators and the like. This is important when there are epidemics, as it is very difficult to isolate students due to lack of space. In many cases there is also no optimal air renewal. The present invention prevents contagion of all types of germs by using additional individual aeration systems.

Objective pursued with this product and its advantages.

Provide a system that:

It is simple, inexpensive, useful, which prevents viruses, bacteria and protozoa or parasites.

It can be used for long periods of time.

They can be used during long waits for slow obtaining vaccines or drugs. It is valid for protection in schools and other closed places.

The masks used here do not filter, they isolate the air that surrounds us and also act as a barrier that prevents the rapid transmission of germs.

Current problem.

In schools and other closed places, even open ones with many crowded staff, it is very difficult to avoid the spread or spread of diseases. Being forced to keep distances that make them unprofitable. The masks are not totally effective, they partially filter and do not protect the user or those around them. As an example, the FFP-2 and FFP3 with a valve, if the user is infected, they exhale and the microbes are not filtered during exhalation, which causes those who wear it to believe that they are protected, trust themselves and visit dangerous or contaminated places. Very important when it comes to virus epidemics, since it takes a long time to obtain vaccines or drugs for their treatment. By not being able to attend class the students produces a very important problem that must be added to the health and economic one.

The anti-germ protection system for schools and the like of the invention uses a system that prevents germs: bacteria, viruses, protozoa or parasites from being breathed into the rooms. classrooms or closed places, characterized in that a system is used that breathes or sucks air into the individual area of each student, using compressors or fans, air supply or suction ducts, masks, partitions and screens or membranes , which allow students to breathe in isolation. It is also essential that the classrooms are sufficiently ventilated.

Additional partitions with curtains can be used for additional isolation in the case of suspected or infected students, thereby increasing protection.

Air is blown or sucked into the student's area, at the desk, or around their head. The air can be supplied by means of elevated, suspended ducts, by or under the ground, from where it is forwarded to the desk or area close to the student. An area or space can be created around the head, where the air is blown or sucked in, an area that can be formed or obtained with: a) a cover or screen, b) a hood that is fastened while simultaneously covering the backrest c) a hood with protruding side flaps that simultaneously carry holes or slots through which air is blown, d) flexible side plates or sheets, e) flexible and extensible ducts from the desk, its base or from the seat area, which allow its addressing. These previous systems, flexible and transparent, create a semi-independent chamber around the student's aspiration area, which when the air is blown in, a slightly pressurized area is produced and when it is sucked, they create a depression. Optionally and individually some controls can control the temperature and the air flow. Suction or insufflation can be done with ducts flattened on the floor.

The masks are insulating. They are disposable, portable or use a quick coupling fitting on the desk seats or on the floor or added conduit for this purpose. They can be disinfected or discarded. Filtering masks can be used to go to the lavatory - but these may be appropriate. However, the main classroom aeration, along with the systems used, can help keep classrooms lightly contaminated. Especially if the suction system is used.

The systems mentioned here can be connected or complemented with each other.

In many cases, a mask is not necessary. In recesses distances can be better maintained since there is not so much space problem.

THE AIR INSUFFLATED OR SUCKED IN THE SUCTION AREA OF EACH STUDENT, WITH OR WITHOUT COVER, SCREEN OR HOOD, INCREASES OR REDUCES THE PRESSURE OF THE SAME, PREVENTING THE BREATH OF POLLUTED AIR.
