PROTECTIVE BARRIER SYSTEM AGAINST HARMFUL SUBSTANCES

DESCRIPTION

Technical field and object of the invention

The present invention is encompassed within the technical field of protective devices for care environments for people in hygienic conditions, preferably for health care in dental consultations, but extendable to other health fields, such as dermatology, podiatry or surgery, or even for beauty parlors, tattoo parlors or even jewelry workshops, in short, in any work environment in which gases or harmful particles are generated.

An object of the invention is to provide a protective device against harmful substances, such as aerosols, droplets or splashes, which may involve contagion by transmission of viruses, bacteria, pathogens, etc., while allowing the professional who attends a patient perform their work in complete safety, comfort, and good lighting.

Another aspect of the invention relates to a dentist chair incorporating the aforementioned device.

Background of the invention

In dental practice, the generation of aerosols is frequent, which implies a high risk of contamination of health personnel with viruses or pathogens, so it is necessary to have protection means during work that generate and disperse aerosols in the environment.

These situations are frequent during dental treatment, creating potentially dangerous situations not only for dentists but also for auxiliary personnel, the patient himself and the rest of the patients who later come to the clinic, since the vapors can remain in suspension favoring the spread of viruses.

They are known screens for health personnel that are fixed to the head, but that are uncomfortable and make it difficult to carry out their work. Description of the invention

The invention solves the aforementioned problems, providing a protective barrier system against harmful substances such as aerosols, splashes and droplets that may involve contagion by transmission of viruses, bacteria, etc., and also provides protection against mercury aerosols that are generated when handling silver amalgam. The system of the invention is easy to use and does not imply any discomfort to the professional who attends a patient or person to be treated, nor does it hinder their work.

More specifically, one aspect of the invention relates to a barrier protective system comprising a transparent screen usable as a barrier means between a patient and a healthcare professional during their professional work, and an aspiration duct provided with a plurality of holes, which communicate the aspiration duct with the outside of the screen support.

The orifices are distributed to produce aspiration in a containment zone defined by the transparent screen, so that the aspiration and evacuation of aerosols occurs throughout the treatment space of a patient.

The system also comprises: an articulated arm, coupling means for coupling the screen with the articulated arm, and a suction system to produce suction inside the suction duct, so that the holes that are distributed around the entire perimeter of the screen produce aspiration in a wide area of work.

Preferably, the articulated arm is watertight, and the suction means are adapted to produce aspiration in the aspiration conduit through the interior of the articulated arm.

The system incorporates electrical wiring that preferably runs inside the articulated arm to power the lighting system and / or any electrical device that is commonly used in a dental clinic, beauty salon, tattoo parlor, etc.

Preferably, the system also comprises a screen support that is in the form of a perimeter frame, and that is attachable to the articulated arm. The support of The screen also integrates the aspiration duct, which runs along the perimeter of the support itself, so that the support has two functions, that of supporting itself and that of conducting and distributing the aspiration throughout the work area.

Preferably, the screen and the support are configured such that the support can be coupled to the perimeter edge of the screen, and further comprises fixing means for removably joining the screen and the support.

In an alternative embodiment, the screen and the screen support are a single piece, so that the transparent screen itself integrates the aspiration conduit and the holes.

Preferably, the screen support has a circumferential, ovoid or polygonal shape, and the suction holes are distributed around the entire perimeter of the support.

In a preferred embodiment, the support is circumferential and the screen is shaped like a spherical cap.

The system also comprises lighting means integrated in the support or in the screen, which are adapted to illuminate a work area comprised inside the support and below it.

In a preferred embodiment, the screen support incorporates a channel that extends around its entire perimeter, and a cover that can be attached to the channel, so that when the cover and the channel are coupled, they form the conduit to produce aspiration through the tubes. holes.

In a preferred embodiment, the system further comprises a transportable trolley, and the articulated arm is removably attachable to the trolley. The suction means are housed within the transportable cart.

Additionally, the articulated arm is adapted to be coupled to a dental clinic chair.

Additionally, the articulated arm is adapted to be coupled to a pre-installed suction installation in a clinic or workplace in question. Conventionally, these suction installations comprise construction pipelines and a machine room in which the suction machinery is located. The articulated arm would be connectable to a suction outlet of the installation, and the trolley with the suction means could be located in the engine room.

Another aspect of the invention refers to a dental chair that incorporates the previously described barrier protective device coupled to the chair structure, in a position that acts as a barrier between a patient sitting in the chair and a healthcare professional.
