Description

FACIAL PROTECTION DEVICE FOR SUPPORT AND SUPPORT IN SURGERY

TECHNICAL FIELD OF THE INVENTION

The present invention is related to the technical field of facial protection devices, particularly those used in medical-surgical environments, which is a facial protection device that, in addition to providing protection to a user in environments with dispersed aerosols. that constitute a risk of contagion by contact or aspiration of harmful agents, supports procedures such as surgical interventions, with which the activities carried out are also recorded, which serve as evidence support for various purposes.

BACKGROUND

Protective equipment should be worn during medical procedures and patient care activities when contact of clothing, or exposed skin, with blood, bodily fluids, secretions, or excretions is anticipated. Also, when there is a possibility of splashing or spillage, when mixing or administering hazardous drugs, such as in the case of surgeries.

Mouth covers or masks, respiratory protectors and any facial protection device are mainly used to protect the mouth and nose during medical, surgical or laboratory procedures, since they prevent the transmission of infections by contact with splashes of body fluids or aspiration of microparticles suspended in the air. Therefore, they must be resistant to fluid seepage. For added isolation, some masks have a flexible piece, which fits into the upper base of the nose and helps to secure the mask perfectly over the entire area.

There are different types of masks, depending on their application: for surgical, dental, medical, isolating, and laser procedures. They are made of delicate materials, are available in one size, and should feel comfortable to wear.

Respiratory protectors filter the air before it is inhaled, to protect healthcare personnel from hazardous or infectious aerosols, droplets of respiratory fluids, and other airborne particles. They must be adjusted to the face and form a hermetic seal over the nose and mouth. Therefore, it may be uncomfortable to wear them. The National Institute for Occupational Safety and Health, of the United States, recommends the protectors N95, N99, N100. This standard does not coincide with the European one, where the certified equipment is FFP1, FFP2 and FFP3 (UNE-EN 149:2001) and P2 (UNE-EN 143:2000). Each provides a different level of respiratory protection.

Masks and respiratory protectors should be used if the patient is suspected of having an airborne disease, or if they are going to be exposed to hazardous gases or vapors. The decision to use one or the other depends on the risk involved. For example, N95 respiratory protectors should be used if the patient has infectious tuberculosis. However, if it is to be done a bronchoscopy in this patient, health personnel must use a respiratory protector that provides greater protection.

Goggles provide a barrier of protection for the eyes. They should be comfortable to wear and provide good coverage over the eyes or personal lenses. Some glasses have anti-fogging properties, which help maintain clear vision.

Face shields, on the other hand, are used when full face protection is required, for example, when a wound is irrigated, abundant secretions are suctioned, or there is the possibility of splashing hazardous drugs. Face shields must cover from the forehead to below the chin, and extend to both sides of the face. They can be used as substitutes for glasses.

Various devices for facial protection have been developed, which is why a search for the state of the art on facial protection devices for support and support in surgeries was carried out, where the United States patent document US 10908681 (B2) was found. ) published on February 02, 2021 which discloses a device mounted on the head of a user; The device includes an image capture device configured to capture an image of a surgical environment and clear lenses configured to display a magnified image. An eye tracking module coupled to the transparent lens configured to determine a gaze direction of an eye or the wearer, wherein the eye gaze direction determined by the eye tracking module is used to manipulate the eye tracking module. enlarged image. On the other hand, the United States patent document US 10646283 (B2) published on May 12, 2020 with the title "AUGMENTED REALITY NAVIGATION SYSTEMS FOR USE WITH ROBOTIC SURGICAL SYSTEMS AND METHODS FOR THEIR USE" describes a augmented reality navigation system and methods of its use which, among other applications, addresses the need for systems and methods of robotic surgical application navigation systems.

Even when assistance devices are known during the performance of activities such as surgical activities, where there are image projection systems among other support peripherals, said inventions lack means that generate a physical barrier to prevent aerosols of body fluids from and other noxious substances dispersed in the work environment are conducted towards the respiratory tract or eyes where they can be deposited and infect or cause damage to the personnel who work in said conditions.
