FIELD OF INVENTION
The present invention refers to the field of medical device; more specifically it discloses breath isolation device and disinfecting device to clean the infected breath before release into the air.
BACKGROUND OF THE INVENTION
The world today is facing a global pandemic CO VID- 19 causing deadly respiratory infection/failure. The virus is rapidly spreading to countries pan globe and the cause of multiple deaths worldwide. Unlike previous deadly viruses like HIV etc. CO VID- 19 poses the greater problem of communicability by social contact and that is the key reason for a rapid global spread. The novel corona virus that cause COVID-19 spreads primarily through ‘respiratory droplets’ generated when an infected person coughs, sneezes or speaks. Virus comes out through the breath of the infected person as these ‘respiratory droplets’ which when inhaled by another person, infect him / her leading to spread of infection. Respiratory droplets also fall down contaminating surfaces with viral particles. People can also become infected by touching these contaminated surfaces and then touching their eyes, nose or mouth before washing hands.
Solutions like social distancing, using masks (especially effective N-95), head-shields, hand hygiene, sanitization, wearing PPE etc. are taken to stop spreading the viruses. These methods depend on Natural decay / death of the virus, which can take several days to weeks. Therefore increasing chances of a highly infectious agent like COVID- 19 is still prevailed. World is still awaiting the effective antiviral drugs and vaccines.
Importance of the present invention In this global crisis situation, present invention is showing a ray of hope to cease spreading infection in the environment. The present invention relates to a special device, which can capture the breath as soon as it conies out from an infected person and sanitize it to deactivate/kill the virus before releasing the breath in to the environment. Keeping in mind that virus is constantly coming out from the infected people and contaminates the air, healthy people uses masks, PPE etc. But, the present invention helps to sanitize the contaminated exhaled breathe of infected patients before getting contact with the environment in a definite way. Thus it protects environment as well as healthy people from deadly viruses at the very first step. Unlike vaccine, wearing masks, it is applied to the sick / infected persons, not to the healthy people. The present invention is very useful in hospital, health care unit and isolation zone as well as in home. It can be used for a variety of infections that spread through respiratory system.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to the special device which can capture the breath as soon as it comes out from an infected person and sanitize it to deactivate/kill the virus before releasing the breath in to the environment. This special device can protect the people from getting infected and can stop spreading the infection in a mass scale.
Constructional Details The present invention connects with a commercially available face mask. The mask is connected to a corrugated tube (Figure 3) through an adaptor (Figure 4). The adapter is specially designed to incorporate two unidirectional valves (Figure 4a, 4c) to control the flow of air/breath. It has four ports. a) Inlet port (Figure 4a) which allows the fresh air (room air) to be breathed in or inhaled. Person cannot breathe out through this port as it is a one-way port. b) Outlet port (Figure 4c), which is like an exhaust port through which breathed out (exhaled) air passes. Person cannot inhale through this port. This port is connected to the sanitization chamber (Figure 1) through a corrugated tube (Figure 3). c) Respiratory port (Figure 4b), is connected to the face mask and patient breaths in and out through this port. d) Oxygen port (Figure 4d) which normally remains closed but can be used to attach oxygen supply line if patient needs it.
Corrugated tube (Figure 3) is one and half meter long flexible tube of large diameter (22mm internal diameter) that connects outlet port of the face mask adapter to the sanitization chamber (Figure 1). It carries the exhaled (infected) breath to the sanitization chamber.
Corrugate tubing connects to the intake port of the Dual Channel T-tube (Figure 5). T-tube has three parts, those are (a) an intake port (Figure 5a), (b) an exit port (Figure 5b) and (c) a 2 channel segment (Figure 5c). Intake port leads to channel one (Figure 5d) of the dual channel segment, lower end of which dips into the disinfectant solution.
Aerosol protector (Figure 6) is a perforated disc attached to the lower end of the dual channel segment of the T-tube prevents large air bubbles from bursting at the fluid air interface.
Sanitization Chamber (Figure 1) is a transparent jar made of unbreakable polycarbonate material. It has an airtight lid (Figures 2; 7; 9, Figure 8) which holds the T-tube with aerosol protector. The lid, T-tube and aerosol protector are joined together as a single unit to prevent wrong connections and leakage. Sanitization chamber contains disinfectant solution. Although 0.5% - 1% Sodium hypochlorite solution filled to the desired level is recommended, but any tested liquid disinfectant can be used with this device.
Working method and method of detection:
The working method of this present invention is described here. The device connects to certain face masks which are available commercially. Face mask is applied in manner that it could cover the patient’s mouth and nose and there should not be any leakage of air or breath around the edges of the mask. Inhalation occurs through the inlet port (Figure 4a) of the unidirectional valve (4a) of the adapter (Figure 4). Exhaled air is pushed through the outlet port (4c) of the adapter (Figure 4) into the Dual Channel T-tube (Figure 5) through intake port (5a) connected to the corrugated tube (3). Infected breath enters channel one (5d) terminating in disinfectant solution. Respiratory droplets containing viral particles coalesce with the disinfectant solution thereby exposing viral particles to the disinfectant. The exhaled air bubbles come out of the surface of the disinfectant solution through channel two (5e) towards exit port (5b). Aerosol Protector (Figures 6; 6, Figure 9) traps any aerosol generated while exhaled air bubbles escape towards exit port (5b).
In this novel method, the present invention does not allow the patient’s virus containing exhaled breath to mix up in the environment and therefore the device disinfects the exhaled air internally and only after that it allows to release in to the environment. The device is specially designed to prevent the environment pollution from an infectious agent. This is the most effective device at the time of COVID-19 pandemic to stop spreading the virus in mass scale.
The novelty in the present invention lies in the fact that a comprehensive system which can capture the breath as soon as it comes out from an infected person and sanitize it to deactivate/kill the virus before releasing the breath in to the environment. No such device or mask is disclosed in any of the patents or publications and also online commercial information sources. The technological advancement of the present invention is to disclose a device in the form of a mask wherein the patient’s exhaled breath comes in contact with the disinfectant solution through one-way flow all the way. The respiratory droplets containing viral particles coalesce with the solution here. The exhaled air bubbles come out of the surface of the disinfectant solution. Finally the exhaled air gets disinfected and escapes out from the sanitization chamber through the exit port.
Although facial mask, PPE, sanitizer etc are available to fight with corona viruses, the present invention poses a unique and duly inventive method where the device ceases the infected droplets to release in to the environment in a very definite way. Thus it protects environment as well as healthy people from deadly viruses at the very first step and the environment remains fresh and healthy. Unlike vaccine or wearing masks, it is applied to the sick / infected persons, not to the healthy people.
The present invention is the need of the hour in view of present global crisis. It is very useful in hospital, health care unit, and isolation zone as well as in home. It can be used for a variety of infections that spread through respiratory system. It is an industrially most viable system as on today. The system can be made and sold at an industrial level and the production may run into thousands of such systems.
