[0001] This invention relates to the field of biomedical engineering, more particularly a device (Oxygen Re-Use Breathing System) to recycle oxygenated gas from mechanical ventilator exhaust port to another oxygen needy patients, so it acts as an Emergency Life-Saving Nonrebreather Mask (ELSN) and circuit in the expiratory port of ventilator attachment. It aims to mitigate mortality rates during emergencies caused by oxygen shortages, utilizing a non-electronic, disposable system. The device collects wasted oxygen from ventilator exhaust, filters it, and redirects it for use in oxygen-needy patients via specialized masks and reservoir bags. Key components include a flexible gas-receiving tube, a double one-way valve 'Y' piece connector with microfilter, and collapsible rubber reservoir bags.

[0002] During COVID- 19, A considerable number of COVID- 19 patients require mechanical ventilation and frequently require high 02, even up to 100% of FiO2 (Fraction of Inspired oxygen). However, less than 5% of the oxygen is necessary for the patients (uptake of the patient). As the ICU ventilators often do not have a closed recycling system, more than 95% of the pumped gas (Oxygen) is vented out through the expiratory limb and finally through the exhaust into the atmosphere. Accumulatingthis exhaust gas and then supplying it to other needy patients can help tide over the crisis to a great extent.

[0003] COVID- 19's first and second waves devastated humankind worldwide; several hospitals have reported shortages of medical oxygen for a growing pool of patients needing oxygen support, endangering their lives. In COVID and other emergency mass causality areas, when the patient is on NIV (Non-Invasive Ventilation), we were given 60-100% of Fio2 (Fraction of Inspired oxygen). For example, if we are setting 100% of FiO2 and tidal volume is 500ml per breath, approximately 90% (450 ml per single breath / single patient) of oxygen is getting wasted by releasing into the atmospheric air through the expiratory port of the ventilator. We are losing a large percentage of oxygen into the atmospheric air. So, this oxygen can be utilized for another NRBM patient by placing an appropriate viral filter, which can save the patient’s life for some hours to days until the availability of oxygen beds in the same or other hospitals.

[0004] In the Normal physiology of respiration, we inhale approximately 21% of oxygen, 0.04% of carbon dioxide, 78% of Nitrogen, and rare gases and exhale 16% of oxygen, 4% of carbon dioxide, and 78% of Nitrogen. But when the victim got arrested, and there was no availability of a bag mask or artificial ventilation so we used MOUTH to MOUTH breathing for life-saving even though it had less oxygen and a more carbon dioxide ratio still, it is acceptable for life-saving priority. In the same way, when we don’t have sufficient oxygen beds, we can use this invention Ventilator Exhaust Oxygen Re-Use Breathing System (ELSN Circuit) as a priority lifesaving method. The war between the countries can to affect the military and ordinary people so it making mass causality occur in nearby health care sector and hospitals / triage places and the peoples involved with Road, train and ship accidents also make the same, so in this human induce hazards we need provide and arrange the emergencyoxygen supply and oxygen bed more in number with the immediate phase. Like an unexpected lifesaving emergency crisis, we must recycle the exhaust-wasting oxygen.

[0005] Human activities are at the root Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures even higher in the poles, and as a result, glaciers are rapidly melting in arctic and Antarctic calving off into the sea and retreating on land ongoing this movements world can possible to face new bacterial, viral and unknown microorganism induce pandemic and epidemic respiratory disease spread and other diseases too. The increasing global population, particularly in developing and underdeveloped countries, has created a lot of population and a lack of oxygen beds in their hospital setup. So, fewer specialty health care systems can’t manage mass causalities, such as the COVID pandemic, epidemic, emergency uncontrolled fire, flood, tsunami, earthquake, and unexpected natural disaster management.

[0006] To solve the above-mentioned problem, here is a device for Recycling Oxygenated Gas from a Mechanical Ventilator Exhaust Oxygen Re-Use Breathing System for another patients (Emergency Life-Saving NRBM (ELSN) circuit is disclosed. This solution is tailored to meet the escalating oxygen demands of ongoing and future emergency crises. The ELSN Circuit offers a groundbreaking method to repurpose this valuable resource for other oxygendependent patients by harnessing the high-oxygen gas released from ventilator exhaust. With its non-electrical design, this innovative circuit bolsters bed capacity and oxygen supply within critical healthcare settings, including emergency management centres, triage areas, ambulances, and hospitals. This device promises to optimize resource utilisation, ensuring enhanced patient care and effective emergency healthcare delivery during times of heightened demand.THE OBJECTIVES OF THE INVENTION:

[0007] The principal objective of the invention is a non-electronic, single-use disposable device to mitigate mortality rates during emergency lifesaving crises caused by oxygen shortages. This device operates in conjunction with a Mechanical Ventilator, where exhaust oxygen is collected, filtered, and recycled into the Emergency Life-Saving NRBM (ELSN) circuit (Oxygen Re-Use Breathing System) catering to the oxygen needs of other critical patients.

[0008] Another objective of the invention is a cost-effective method to significantly increase oxygen bed capacity during mass casualty events without relying on central oxygen systems or cylinders. By leveraging existing mechanical ventilators, this device enhances emergency response capabilities, potentially doubling or tripling bed strength.

[0009] The further objective of the invention is to reducing mortality rates stemming from oxygen shortages during public health crises such as pandemics and epidemics caused by respiratory diseases. By addressing unexpected oxygen shortages, it also aims to minimize casualties in military and civilian populations during war time emergencies.

[0010] The further objective of the invention is in preventing human fatalities during natural disasters like fires, floods, tsunamis, earthquakes, where oxygen shortages are common. Recycling oxygen prevents wastage of this vital resource and ensures its efficient utilization during crises.

[0011] The further objective of the invention is to facilitate intermittent aerosol- medicated nebulization and provide humidified oxygen without electronic devices, utilizing the pressure from ventilator exhaust gas. This versatile functionality enhances patient care in emergency settings without the need for additional equipment.

[0012] The further objective of the invention is to prevent and reduce mortality rates in high-tech ambulance services, particularly in managing accidents involving road, train, and ship transport, where localized oxygen shortages can occur.

[0013] The further objective of the invention is to provide conventional approaches to oxygen therapy, including NRBM, oxygen face masks, and nebulization masks, catering to diverse patient needs within emergency settings.SUMMARY OF THE INVENTION

[0014] COVID- 19, biological health hazards (respiratory pandemic and epidemic diseases spread), human-induced health hazards (war and vehicle accidents), and natural-induced health hazards (Tsunami and floods) are many patients were not getting oxygen during the emergency mass causality, and some patients are dying due to not being administered oxygen at the right time, like critically ill patients from COVID- 19 mass causality. In the mechanical ventilator, we were given 60-100% of Fio2 (Fraction of Inspired oxygen). For example, if we are setting 100% of Fio2 and tidal volume is 500ml per breath in approximately 90% (450 ml per single breath / single patient) of oxygen is getting wasted by releasing into the atmospheric air through the expiratory port of the ventilator.

[0015] wastage of oxygen calculation per single patient on 24 hrs. or one day; (Minute volume wastage of oxygen =Tidal volume wastage (450 ml) oxygen *Respiratory Rate(20b / mts),450*20=9000ml per minute and for one hrs. wastage of oxygen = 9000*60=540000ml of oxygen, per day 24*540000=12960000(12960 liters) ml of oxygen we are wasting for single ventilator patients but patients need of oxygen just 14401itures perday. so, we are losing a large percentage of oxygenl2960 liters into the atmospheric air.

[0016] This invention describes a device (Exhaust Oxygen Re-Use Breathing System) for Recycling Oxygenated Gas from a Mechanical Ventilator Exhaust oxygen for another patients (Emergency Life-Saving NRBM (ELSN) circuit). This circuit presents a vital solution to address oxygen shortages during crises, potentially saving the lives of low-flow, oxygendependent patients. By utilizing this single-use, disposable, nonelectronic ELSN circuit, excess oxygen from one ventilator's exhaust port can be redirected to other patients in urgent need. This life-saving intervention offers crucial support until additional oxygen beds become available in the same or other healthcare facilities, spanning hours to days.

[0017] Moreover, this device helps alleviate oxygen scarcity and indirectly boosts bed capacity with oxygen supply during emergencies or mass casualty incidents. The risk of cross -infection is minimized by including two viral filters in series, effectively filtering out approximately 99.99% of expired viruses. Furthermore, concerns regarding CO2 retention and inhalation are mitigated as the concentration of CO2 in the delivered gas remains below 2%, well within acceptable limits for low-flow an aesthesia without adverse clinical effects.

[0018] Ethical considerations are also addressed, recognizing the device's purpose to alleviate crises. While using expired gas from one patient for another may raise ethical dilemmas, the device (Exhaust Oxygen Re-Use Breathing System) serves as a vital life-saving measure for patients facing imminent oxygen deprivation, akin to other accepted life-saving interventions like mouth-to-mouth resuscitation for cardiac arrest victims. The device for Recycling Oxygenated Gas from Mechanical Ventilator Exhaust for Emergency Life-Saving NRBM (ELSN) Circuitoffers a comprehensive solution for current and future emergency oxygen requirements. Its implementation in emergency management sectors, triage locations, ambulance services, and hospital setups promises to enhance oxygen supply, bolster bed strength, and save lives during critical healthcare scenarios.DETAILED DESCRIPTION OF THE INVENTION

[0024] The present invention is a device for Recycling Oxygenated Gas from a Mechanical Ventilator Exhaust for an Emergency Life-Saving NRBM(ELSN) Circuit (Oxygen Re-Use Breathing System) designed to mitigate mortality rates during critical emergencies, particularly those caused by oxygen shortages. Operating alongside a single Mechanical Ventilation system, this non-electronic, single-use disposable device collects, filters, and redistributes exhaust oxygen into the ELSN circuit to meet the urgent oxygen needs of patients facing life-threatening situations.

[0025] Comprising several key components, the Emergency Life-Saving NRBM (ELSN) ( Oxygen Re-Use Breathing System) circuit includes a primary gas receiving flexible plastic tube with an adjustable adaptor(A), a doubled one-way valve 'Y' piece connector with a microfilter unit(B),, a non-collapsible hollow rubber-made gas facilitator unit(C), a collapsible rubber-made gas collecting and compressing primary reservoir bag(D),a gas-delivering flexible plastic tube with an adaptor(E), and a specialized non-rebreather oxygen reservoir mask and bag(F).

[0026] The primary gas receiving flexible plastic tube with an adjustable adaptor serves as the conduit between the ventilator exhaust opening and the doubled one-way valve 'Y' piece connector unit. Specifically designed for a secure connection, the tube's ventilator end features a specialized adaptor with movable parts that adjust to the ventilator exhaust port's size, ensuring a tight and sealed attachment. This tube promptly receives the ventilator exhaust gas and channels it to the 'Y' piece connector unit for further processing. (Component A) Fig;l&2)

[0027] Here, in the doubled one-way valve, the 'Y' piece connector with the microfilter unit plays a crucial role in the ELSN circuit. One end of this transparent 'Y' piece connector is linked to the primary gas-receiving flexible plastic tube. At this point, an inner one-way valve prevents gas from flowing back to the ventilator exhaust port. On the other end, the 'Y' piece connects to the non-collapsible hollow rubber-made gas facilitator unit. Here, the 'Y' piece features an external one-way valve to facilitatethe provision of atmospheric air in case of reduced air pressure within the circuit. This feature ensures the ELSN circuit can supply atmospheric air even if the ventilator fails to deliver exhaust gas. (Component(B) Fig;12,l&2)

[0028] Patients connected to the 'Y' piece connector benefit from additional features such as a viral filter, ETco2 port, and NASAL PRONGS connector port for second patients requiring lower oxygen levels. Positioned above and at the center of the 'Y' piece are hanging hooks designed to support and maintain the ELSN circuit's posture, effectively bearing its weight during patient usage. These hooks enhance the circuit's usability and ensure optimal functionality throughout patient care. (Component(B) Fig;12,l&2)

[0029] The non-collapsible HOLLOW rubber-made gas facilitator unit serves a critical function in the ELSN circuit by facilitating the delivery of gas to the collapsible rubber-made gas-collecting primary reservoir bag. This hollow rubber bag can be manually compressed to pump gas when a ventilator fails to deliver exhaust gas. (Component(C) Fig;3,13,l&2)

[0030] The collapsible rubber-made gas-collecting primary reservoir bag expands under the pressure of the ventilator exhaust gas, temporarily storing the oxygenated gas. As the ventilator exhausts, the pressure on the bag decreases, causing it to contract and collapse due to the nature of rubber and gravity. This contraction pumps the temporarily collected gas out to the patient side of the 'Y' piece, ensuring continuous delivery. (Component(D) Fig;5, 13,1&2)

[0031] The gas-delivering flexible plastic tube with an adaptor connects to the 'Y' piece and delivers the exhaust gas to the NRBM mask during both the phase of ventilator exhaust gas pressure and the contraction phase of compressing the primary reservoir bag. Equipped with a small lateralopening and an on-and-off red Butten middle of the adaptor for the NEBULIZATION chamber tube connection, this flexible tube ensures precise gas delivery to the patient. (Component(E) Fig;7,8,l&2)

[0032] The specialized NON-REBREATHER oxygen mask and bag, designed specifically for the ELSN circuit, resemble a standard NRB mask structure. Constructed from transparent rubber mixed with flexible plastic material, the mask is available in various sizes to accommodate different patient faces. It features a flexible metal arch-support at the nose bridge area for support, sealing, and adjustments. The lower part of the mask connects to a non-collapsible oxygen reservoir bag via two one- valve tubular inspiratory openings for exhaust gas supply. Fully sealed to the patient's face with adjustable upper and lower elastic bands, the mask ensures effective oxygen delivery and patient comfort. (Component(F) Fig;ll,14,l&2)

[0033] The Oxygen Re-Use Breathing System -ELSN mask features seven ports, each serving distinct functions with different diameters. On the lower side, two inspiratory one-way valve openings deliver exhaust oxygen to patients and the oxygen reservoir bag. One of these ports connects directly to non-collapsible tubes, while the other is linked to the patient's reservoir bag via an adaptor with an outside-to-inside one-way valve for flow meter oxygen connection usage after centralized / cylinder oxygen supply. (Component(F) Fig; 11 , 14, 1&2)

[0034] Additionally, there are three expiratory one-way valve openings located on the bilateral sides of the mask, ensuring efficient exhalation. One double-sided moving pressure-maintaining valve opening, positioned in the mask's center opposite the patient, activates during non- ventilator patient coughing or forceful exhalation. This valve releases extra pressure and gas to the atmosphere, potentially preventing expiratoryworkload, auto PEEP generation, and CO2 retention in non-ventilator patients requiring oxygen. (Fig; 10 &l l(part 21))

[0035] The Oxygen Re-Use Breathing System airflow of exhaust gas during mechanical ventilator pressure release is directed through the ELSN circuit. From the ventilator expiratory port to the primary gas receiving flexible plastic tube, then to the doubled one-way valve 'Y' piece connector with microfilter unite. At this stage, both sides of the 'Y' piece facilitate air delivery. From there, the gas travels through the gasdelivering flexible plastic tube with an adaptor, reaching the specialized NON-REBREATHER oxygen reservoir bag and mask, ultimately reaching the patients. Simultaneously, the exhaust gas flows through the non-collapsible HOLLOW rubber-made gas facilitator unit to the collapsible rubber-made gas-collecting and compressing primary reservoir bag, completing the circulation within the ELSN circuit. (Fig;3&4)

[0036] During ventilator exhaust pressure, the rubber reservoir bag within the ELSN circuit contracts and collapses naturally due to the properties of rubber and the force of gravity. As this movement occurs, temporarily collected gas is pumped and pushed out to the patient side of the 'Y' piece. From there, the gas flows through the gas-delivering flexible plastic tube with an adaptor, reaching the specialized NON- REBREATHER oxygen reservoir bag and mask before finally reaching the patients. (Component(D) Fig;5, 13,1&2)

[0037] In the ELSN circuit's airflow during intermittent nebulization therapy, the exhaust gas and its pressure released from the ventilator expiratory port travel through the primary gas receiving flexible plastic tube to the doubled one-way valve 'Y' piece connector with microfilter unite. Here, a red color switch on the receiver tube adaptor is pushed downward, moving it inside the tube to occlude 2 / 3 of the diameter, diverting theexhaust gas and its pressure to the nebulization port of the adaptor. The pressure then reaches the nebulization chamber, which converts liquid medication into aerosol medication, delivering it to the patients' right nostrils. The remaining 1 / 3 of the gas pressure assists in lifting the aerosol medicine, ensuring effective delivery to the patient's face, as the main port gas delivering opening in the mask is situated just below the nebulization port opening. (Fig;8,9,7&16)
