Abstract

The filter glasses with temperature monitoring represent a combination of an optically transparent frame (1) inside which is a profiled distribution channel (2) which is connected at one end to the profiled nasal chamber (3) while at the other pan is firmly detachably connected to the profiled hollow wings (6). in the process of breathing, the suction of air is enabled through the profiled hollow wings (6) while the exhalation is allowed by the non-return air filter (5) which is located within the profiled nasal chamber (3). Intake air filtration is enabled by a replacement air filter (14) and an ultraviolet UV lamp (11) located inside the profiled hollow wing (6), Continuous measurement of human temperature is enabled by using a temperature sensor (7) which sends a voltage signal to the microcontroller (8) and based on the value of the measured temperature control lamp (9) lights red or green depending on whether the temperature is within acceptable limits. The entire temperature control and signaling assembly as well as the electric battery (10) is located inside the profiled hollow wing (6). In various situations, when a person breathes only through the nose, the efficiency of air filtration is maximum. Even in situations where a person's mouth is open and breathing takes place through filter glasses with continuous monitoring, their protection of humans from viruses, microorganisms and various particles are of high value.

Description

FILTER GLASSES WITH TEMPERATURE MONITORING

1.TECHNICAL FIELD

The present invention relates to filter glasses with temperature monitoring intended for efficient filtration of the air inhaled by a person with continuous observation of his body temperature and eye protection, according to the International Classification (IPC) classified as: A 62B 18/00.

2. TECHNICAL PROBLEM

Today, there are a large number of different types of face masks designed to filter particulate matter and gas as well as to remove various microorganisms and viruses. Wearing masks in public places, where a safe distance cannot be maintained, can help reduce the spread of various viruses. The protective mask usually covers the mouth and nose, which in a greater or lesser percentage stops the direct penetration of particulate matter and gaseous matter into the human respiratory tract. The effectiveness of protective masks is directly related to the particle size that needs be stopped inside the mask material. On the other hand, the porosity of the mask filter material as well as its physical and chemical properties affect the stopping and accumulation of particles. If the mean particle diameter is smaller than the mean particle pore of the filter material, the particle will pass through the same and the efficiency of the mask for that particle level will be almost equal to zero. The average diameter of the virus is about 0.1 pm and most protective masks cannot effectively protect the human respiratory system. On the other hand, most masks have different effectiveness if the viruses are inside the droplets of liquid that are transmitted to the environment by coughing or sneezing. In this case, the efficiency of the masks is increased, since the diameter of the particles and droplets is many times larger titan the diameter of the virus, but the time of their application is also limited. Therefore, most protective masks are limited to single use. Accumulation of moisture inside the filter material of the mask can cause the appearance of bacteria and various microorganisms in it. Due to these shortcomings, protective masks with a replaceable filter are also in use. No matter which face mask is in question, it geometrically covers most of a person's face. During normal daily activities, a person is forced to take off a protective mask, for example when consuming food, dental and medical examinations of the oral cavity and the like. In these and similar situations, a person mainly breathes through the nose, in order to prevent and control the epidemic of infected persons, in addition to the use of protective gloves and masks, it is also operated to measure human body temperature. Temperature measurements are typically performed at the entrances to the building, the gate to the airport, etc., using non-contact measurement. A person entering these facilities is subjected to a temperature measurement only once during entry. If a person stays in the facility for a long time, all day, their body temperature can rise without being detected in the time. In this way, preventing the spread of the epidemic is delayed and measuring the temperature is less effective.

3. BACKGROUND OF THE INNOVATION

Today, there are many numbers of different types of masks designed to protect the human respiratory tract, for single and multiple use. According to most adopted norms, masks are divided into full face masks, half masks, quarter masks, filter half masks, suction assembly and filters. Devices that purify the surrounding air with filters are considered to be protective means based on filtration. Filtration-based protection includes protection against gases and vapors, protection against aerosols, viruses, microorganisms and various combined protections. Thus, for example, medical / surgical masks are primarily used to protect other persons from exposure to potentially infectious droplets of the person wearing the mask. Their application is one-time. Filtering half masks are classified as personal protection in the context of protection against particles, aerosols and drops, in addition, their application is disposable, while the design is various. Exhaust vaive masks filter inhaled and exhaled air and provide seif-protection and external protection. Vaive masks purifying only the inhaled air and provide self-protection. Filter half masks, in addition to safety at work, can be considered as medical products, if they do not have an exhalation valve. These masks are used when it is known that, appropriate medical care is provided to the infected person, and according to the categorization, they can stop over 95% of the particles, witich depends on the parameters of the filtration itself.

4. SUMMARY OF THE INVENTION The primary object of the invention is to provide protection of the human respiratory tract in conditions where the person has his mouth closed for a longer or shorter period of time and uses only his nose for breathing. In addition to transparently covering the eyes, goggles also cover the nose with one of their transparent parts. Breathing through the nose is enabled profiled channel inside the casing glasses. At the top of the glasses, which closes the nose, there is an opening in the channel that passes through the frame. The frame of the glasses is firmly and inseparably connected to the transparent part that closes the nose. The frame of the glasses is a closed profiled channel that serves to transport air to the transparent part that closes the nose. The intake of air to the transparent part that closes the nose is realized only through the profiled channel inside the frame of the glasses. The frame with a profiled channel is firmly connected to the two wings of the glasses placed on the earn. The wings of the glasses are hollow and composed of two parts, tightly separated from each other. In the arched part of the hollow wing there are air intake openings and an electric battery with a charging connection, in the right part of the hollow wing are a miniature UV lamp, a temperature sensor, a microprocessor and signal indicators. Berth hoilow wings have the same internal layout and number of components. All components are interconnected by thin electrical conductors. Voltage to all electrical and control units is provided from the electric battery, separately for each wing of the goggles. The replacement air filter enters the arched part with one end. At the other end, the filter enters the linear part of the hoilow wing. The air filter can be easily and quickly replaced by separating the arched and linear part of the hollow wing. One end of the linear hollow wing is firmly connected to the spectacle frame, i.e. to the profiled air duct inside the spectacle frame. During normal breathing by the nose, when inhaling, the purified air comes through the hollow wings to the profiled channel within the frame and inside the transparent part that closes the nose. On exhalation, a non-return valve opens which is located inside the transparent part that closes the nose. In this way, complete filtration of the transparent chamber that covers the nose is enabled, i.e., proper breathing is allowed. Since the transparent part hermetically closes the nose with its profiled cavity, it is ensured that the filtered air is sucked in and exhaled properly through a non-return valve. During inhalation, the non-return valve on the transparent chamber enclosing the nose is closed, inside the hollow wings it is possible to additionally place a miniature fan to allow for increased air circulation when there is a need for it. A secondary' goal of the invention is to provide continuous monitoring of human body temperature. Therefore, two sensors, one in each wing, monitor the temperature of human skin in the area of the temples (temporal artery). Because the wings of the glasses are close to the temples, constant contact with the temperature sensors is physically possible. By programming the microcontroller, a reference temperature is set, which in fact represents the normal body temperature of a person in the area of measurement, i.e. in the region of the temporal artery, if the temperature diagnosed by the sensors is higher than the reference temperature, the microcontroller sends a signal to the control lamp that glows red. If the temperature diagnosed by the sensors is lower than the reference temperature, the microcontroller sends a signal to the control lamp which will glow green. The choice of color and species of indicator light can vaty in type and performance. In addition to light indicators, vibro or acoustic indicators can also be used to inform a person whose temperature has risen in the meantime. Ail the above advantages in accordance with the secondary goal of the invention will enable the timely diagnosis of fever in people in groups, schools, restaurants and other gathering places, without the need to perform individual temperature measurements. If we take into account that the body temperature of a person staying in an institution is measured only once upon entering it, which is ordinarily the morning hours, then continuous measurement of a person's temperature gets multiple advantages. Other goals and advantages of the invention will be set forth in part in the description which follows, and in part will be apparent from die practice of the invention.

7. APPLICATION METHODS

Filter glasses with temperature monitoring are intended for the protection of the human respiratory system and the simultaneous controlling of his body temperature. The filtration efficiency of these filter glasses is especially when a person, in various situations, breathes and exhales through the nose. Filter glasses are primarily intended for use in protecting humans from various viruses and microorganisms, or particles of different dimensions. By adhering to the nose, filter glasses with temperature monitoring prevent the entiy of unfiltered air into the upper respiratory tract. The series effect of die mechanical-chemical filter and ultraviolet light achieves a high degree of air Filtration efficiency. At the same time, human temperature, as an indicator of possible infection with a viral, is under continuous monitoring, in the described way, the person who uses these filter glasses gives information through signal lamps about his health condition.
