Description

An emergency breathing apparatus using a mouthpiece

The present invention relates to an oral emergency breathing apparatus using a mouthpiece capable of performing emergency rescue treatment or emergency rescue by breathing through the oral cavity at an unexpected disaster occurrence location until a rescue hand is reached by a rescue team.

Due to the development of civilization, the quality of life is changing in various forms as residential life, dietary life, and cultural life are diversified. In the event of an unexpected emergency or emergency, people in crisis often lose their lives without being revived. Occurs.

A typical unexpected emergency disaster or emergency situation in life may be a fire, and other examples include cardiovascular disease and cardiac arrest due to abnormal physical functioning.

In such an emergency, if a professional rescuer arrives to the site within 5 minutes and takes initial action to rescue and emergency patients, the possibility of survival and minimization of damage can be achieved. If you do, your chances of survival will decrease.

As such, the situation in which emergency measures are taken by dispatching to the site within 5 minutes after an emergency situation is called “Golden Time”, which is highly likely to spread rapidly after 5 minutes in the event of a fire, and patients with cardiac arrest are also 4-5. This is because if appropriate measures are not taken within minutes, the survival rate will decrease rapidly.

Therefore, the fire department operated by a professional emergency response team is operated with the goal of arriving at the site within 5 minutes (golden time) for the life of the patient and extinguishing the fire while instructed to dispatch.

However, it is true that it is very difficult in reality for an emergency rescue team to arrive at the site within 5 minutes after an emergency situation occurs.

To reduce personal injury at the site of an emergency disaster, evacuate the victim with a towel moistened with water to prevent inhalation of deadly poisonous gas, or cover the mouth and nose with a water-soaked towel even for unconscious persons. It is rescued in a state of condition, but the situation at the site is so urgent that it is not properly implemented, resulting in personal injury.

In addition, even for those who lose consciousness due to sudden shock and cardiovascular disease, the situation is instructing them to continue CPR until the emergency rescue team arrives.

Therefore, in order to minimize personal injury by avoiding inhaling toxic gases at the site of an emergency disaster, as well as during the golden time, inhalation of the filtered air into the oral cavity and exhalation. By providing a mask with a breathing method that is discharged through the nose, a mask with improved hygiene that lowers the lung disease rate of the human body is provided, and most of the inhalation of harmful gases can be blocked at the fire site by simply inserting the mouthpiece into the mouth. It is possible to prevent suffocation accidents caused by harmful gases and smoke through the lungs, and a mouthpiece that allows soldiers and industrial workers to breathe in purified air inevitable in the weather where fine dust lasts for several days. A mask having this has been proposed as Korean Patent Publication No. 10-2019-0030427 (hereinafter referred to as'pre-publication').

According to the prior disclosure, in the mouthpiece, the mouthpiece and the mask provided with the same include: an insertion part inserted into the oral cavity, forming a first partition wall inside, and forming a plurality of ventilation holes; A body portion connected by the insertion portion and formed of a cylindrical chamber, and having an air purification filter formed in the chamber; And a coupling portion formed on the other side of the body portion and forming a second partition wall having a plurality of ventilation holes. It has a configuration including.

The pre-disclosure made in this configuration can reduce the lung disease rate of the human body by providing a breathing mask that allows the air filtered into the mouth to be inhaled in an inhaled state and discharged through the nose in an exhaled state, and can reduce the lung disease rate of the human body. Just by inserting it into the mouth, it is possible to block most of the inhalation of harmful gases at the fire site, so it is effective to prevent suffocation accidents caused by harmful gases and smoke through the lungs.

However, as for the mask, by combining the mouthpiece 10 formed with the oral insertion part 11 that can be inserted into the oral cavity at a predetermined position inside the mask, the purified external air is sucked into the oral cavity and discharged through the nose, resulting in yellow dust, or In addition to being able to protect the lungs from contaminated air and harmful gases, it is a structure that supplies and circulates purified air by being inhaled as purified air through the filter 20 in the chamber 16. Since the removal of contaminated air and harmful gases depends only on the performance of the filter, there is an unstable problem.

The mouthpiece 100 is a breathing device that is inserted into the mouth and has a structure capable of breathing through the oral cavity. In addition, when the mouthpiece 100 is rescued at a disaster site and inserted into the mouth of a patient who needs emergency measures, it becomes a safety device that prevents a phenomenon in which the tongue blocks the airways.

An induction tube 200 is formed in the front of the mouthpiece 100, and a cartridge 400 capable of providing air required for breathing is formed in the induction tube 200.

2 is a cross-sectional view showing the internal structure of the oral emergency breathing apparatus to which the present invention is applied, and the internal structure of the mouthpiece 100 and the cartridge 400 is described.

The present invention provides an optimal environment suitable for protecting and rescue of valuable life by supplying enough air to emergency rescue workers or evacuees and emergency treatment targets (patients) in an emergency disaster site by mouth through mouth. An induction tube 200 is formed on the front surface of the mouthpiece 100 to induce only breathing, in which air inhalation and exhalation into the oral cavity are respectively controlled.

The induction pipe 200 includes an intake hole 203 in which the intake control valve 230 is mounted and an exhaust hole in which the exhaust control valve 240 is mounted in which the central position of the hollow flow path is divided by a partition wall 201. 205 is formed, and a filter 250 for purifying foreign matter and toxic smoke is mounted on the front surface through which air is introduced and exhausted.

An emergency airbag 300 for providing air required for oral breathing is installed in the guide tube 200.

The emergency airbag 300 expands into an internal volume capable of accommodating a sufficient amount of air to withstand the golden time of a disaster relief, and is made of a shrinkable vinyl or rubber material when stored, and a carbon dioxide absorbent is administered to the internal volume.

The carbon dioxide absorbent is for removing carbon dioxide contained in exhausted into the emergency airbag 300 through the mouthpiece 100 during oral breathing, and is to re-inhale the air from which carbon dioxide has been removed to allow repeated breathing.

The front side of the guide tube 200 is provided with a cartridge 400 that stores the contracted state of the emergency airbag 300 and forms an expanded state during emergency breathing.

The cartridge 400 is provided with a first hole 401 for storing the emergency airbag 300 in an unfilled state, and a second hole 401 for storing air for injection into the emergency airbag 300 at the same time. A hole 403 is provided.

The first hole 401 is formed to be concave in a cone shape so that the guide tube 200 is connected to the concave central position, and the emergency airbag 300 stored at the entrance of the first hole 401 is A cover 410 is provided to conceal until air is filled for emergency breathing.

In addition, the second hole 403 is integrally connected to the first hole 401 and is formed as a space suitable for mounting a filling bag 450 for supplying air to the emergency airbag 300. .

The filling bag 450 is made of a material that is free of contraction and expansion, and is mounted in the second hole 403 in a state in which air is filled and expanded in a state in which the emergency airbag 300 is stored.

An expansion member 430 for injecting the air filled in the filling bag 450 into the emergency air bag 300 is provided in the second hole 403 of the cartridge 400.

The expansion member 430 is an explosion in which an instantaneous expansion force is generated due to ignition of gunpowder in the fixed jaw 405 protruding from the inner surface of the second hole 403 in the spatial direction of the second hole 403 The part 433 is mounted, and an ignition line 435 extending from the explosive part 433 and exposed through the cartridge 400 to ignite the explosive part is provided.

The air filled in the filling bag 450 is moved toward the emergency airbag 300 by the sudden expansion force generated by the explosive portion 433 of the expansion member 430, and for this purpose, the guide tube 200 A through hole 260 for moving air is formed on one side thereof, and an elastic valve 270 that is elastically opened and closed by a pressure included in the expansion force by the expansion member 430 is installed in the through hole 260 .

The elastic valve 270 maintains the second hole 403 of the cartridge 400 in a closed state during normal operation, and the expansion pressure of the explosive unit 433 operated by the expansion member 430 during emergency rescue The elastic valve 270 is elastically moved in the through hole 260 to open the through hole 260 that is being closed.

At the same time, the expansion pressure generated by the explosive part 433 compresses the entire outer circumferential surface of the filling pack 450 mounted in the second hole 403, so that the air filled in the filling pack 450 is opened through an open hole. The through hole 260 is in a closed state due to the elastic return force of the elastic valve 270 when the natural pressure is rapidly supplied to the emergency airbag 300 in a small state through 260 and the expansion force is reduced.

3 is a cross-sectional view showing an operation state of an emergency airbag among the oral emergency breathing apparatus of the present invention.

It is very desirable for life protection and lifesaving to use the oral emergency breathing apparatus of the present invention during emergency rescue activities, especially during emergency rescue golden time, in places where an emergency disaster or fire occurs.

In other words. The first thing to do before biting the mouthpiece 100 in the mouth or in a state in which the mouthpiece is bitten is pulling the ignition line 435 drawn out to the side of the cartridge 400.

By pulling the ignition line 435 to achieve a moving state of the characteristic filled air of the present invention in the explosive unit 433 connected thereto, the cartridge 400 due to the explosion of the gunpowder generated in the explosive unit 433 In the second hole 403 of the induction tube 200, the through hole 260 of the guide tube 200 is closed by pressing the outer circumferential surface of the installed filling pack 450 and at the same time, the pressure is concentrated in the elastic valve 270. The elastic valve 270 that was being pressed is pushed by pressure to open the through hole 260 that was being closed.

Therefore, since the filling pack 450 is pressed by the expansion force of the second hole 403, the filled air moves to the emergency airbag 300 through the naturally open through hole 260, and the emergency airbag 300 in a contracted state. The elastic valve 270, which is in a state of being expanded by the injected air and elastically moved by the decrease in the expansion force in the second hole 430, forms a state in which the through hole 260 opened by the elastic restoring force is closed. .

As described above, when the air in the filling pack 450 is moved to the emergency airbag 300, the emergency airbag 300 is in an inflated state. 300) spreads to the entire interior space.

In the state in which the emergency airbag 300 is inflated, the rescuer bites the mouthpiece 100 in the mouth and breathes through the mouth.

When oral breathing is performed, the air filled in the expanded emergency airbag 300 flows into the intake hole 203 through the filter 250 of the induction tube 200, and at this time, the intake valve 230 opens and air goes to the oral cavity. Is inhaled, so breathing takes place.

After breathing, the exhaled air exhausted through the oral cavity does not flow into the intake hole 203 from the induction pipe 200 of the mouthpiece 100, and through the exhaust hole 205 provided with the exhaust valve 240, the emergency airbag ( 300) It moves inside.

At this time, carbon dioxide is contained in the exhaled air, and the carbon dioxide at this time reacts with a component of the filtering member 310, that is, SODA LIME.

The soda lime is a mixture of caustic soda and lime, and caustic soda is a compound of sodium (natrium), oxygen, and hydrogen (NaOH), and lime is a compound of calcium, oxygen, and hydrogen [Ca(OH)2]. When the air contained in the air passes through the filter body 335, carbon dioxide contained in the exhaled air is removed.

That is, the exhaled air is in a state in which carbon dioxide is removed while being in contact with the filtering member 310, so that the exhaled air can be rebreathed.

The air filled in the emergency airbag 300 is inhaled and the exhaled air is also collected in the space of the emergency airbag 300 again, and it is re-breathed, but carbon dioxide is removed each time you exhale, so that the air collected in the emergency airbag 300 is Since the air is saturated with oxygen enough to breathe, the rescuers themselves are in a state of prolonging their lives during the time required to arrive by emergency responders.

In addition, the rescuer rescued at the disaster site also has the mouthpiece 100 of the oral emergency respirator of the present invention bite in the mouth, and the emergency airbag 300 is inflated by pulling the ignition line 433 drawn out to the side of the cartridge 400. This will allow you to supply enough air for breathing until you receive specialized rescue treatment.

The embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, but may be manufactured in various different forms, and those of ordinary skill in the art to which the present invention pertains It will be appreciated that the present invention may be implemented in other specific forms without changing the technical spirit or essential features of the present invention.

Therefore, it should be understood that the embodiments described above are illustrative and non-limiting in all respects.
