Description

Electric positive pressure air respirator

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an electronic malleation air respirator.

Background

Influenza has three types of influenza A, influenza B and influenza C, and the diameter of the influenza virus is 80nm to 120 nm.

The transmission of these viruses or pathogens is through airborne droplets, contact between humans or contact with contaminated products. When people intentionally avoid physical contact between people and do not contact polluted objects or disinfect the polluted objects, the transmission path is only spray transmission. It follows that prevention of droplet transmission is an important method for preventing lung disease. There are thus a number of protective articles for preventing the spread of spray.

Respiratory protective articles are mainly classified into three categories: positive pressure air respirator, gas mask, and respirator.

The positive pressure air respirator is an isolated breathing protection device, and provides breathing protection for workers entering an anoxic and toxic harmful gas environment. During normal use, the pressure in the respirator face guard is a little higher than external environment pressure all the time, and its constitution includes: the gas-liquid separation device comprises a face mask, a gas cylinder, a cylinder belt group, a shoulder belt, an alarm whistle, a pressure gauge, a gas cylinder valve, a pressure reducer, a back support, a waistband group, a quick connector, a supply valve and the like. One cylinder can be used for no more than 1 hour. The total weight of the respirator is above 7.5 kg. And (3) inflating the gas cylinder by using a high-pressure air compressor, wherein the inflation pressure reaches 100kg/cm 2-200 kg/cm 2. The high-pressure air compressor is the necessary inflation equipment of the air respirator, and the cost is about 10 ten thousand RMB. The positive pressure air respirator is expensive, heavy, not suitable for long-time wearing, only suitable for professional use, and not suitable for medical care.

A gas mask is a protective device aiming at protecting individual respiratory tract by toxic gas, which is produced along with chemical weapons, consists of a mask, a gas-guide tube and a canister, and is widely applied to the fields of petroleum, chemical industry, mines, metallurgy, military, fire fighting, emergency rescue and relief, health and epidemic prevention, scientific and environmental protection and the like. A filtering gas mask consists of a face mask and a canister. The mask comprises a mask body, an eye window, a communicator, a breathing valve, a head band (or a helmet) and the like. The filtering canister is used for purifying toxic gas, and is filled with filtering layer and adsorbent, or the filtering plate is made by mixing these 2 materials, and is assembled into filtering element. The lighter (about 200 grams) canister or filter element may be attached directly to the mask, with the heavier canister being connected to the mask by an air duct. The gas mask is generally used in the fields of petroleum, chemical engineering, mines, metallurgy, military, fire fighting, emergency rescue and relief, epidemic prevention, science and technology and environmental protection, and people working in toxic and harmful gas environments also use the gas mask as protection. The respirator and the adsorbent have no physical adsorption removal effect on the aerosol unless the filter layer adopts a material for filtering viruses and pathogens, and the conventional filter layer has no filtration effect on the viruses and the pathogens because the diameters of the viruses and the pathogens are very small. When the gas mask is used, the breathing resistance is large, and the gas mask is not suitable for old, weak, sick and disabled people and is also not suitable for being continuously used by ordinary people.

Protective masks, different countries and regions have different standards. KN series is the Chinese standard, FFP series is the European standard, N series is the American standard, the larger the numerical value the better the filtering effect.

In comparison, FFP3 ═ KN100> FFP2 ═ KN95 ═ N95> KN 90. KN100 indicates a filtration efficiency of greater than 99.75%, KN95 indicates a filtration efficiency of greater than 95%, and KN90 indicates a filtration efficiency of greater than 90%.

KN, FFP and N series of criteria, which are only removal efficiencies for particulate matter, not specific to viruses and pathogens, are used instead.

The Chinese mask for preventing virus is a medical protective mask (GB19083-2010) and a medical surgical mask (YY 0469-2011). The medical protective mask is suitable for protecting respiratory infectious diseases transmitted by air transmission and close contact droplets, and can prevent infection factors with the diameter less than or equal to 5 mu m from being transmitted by air by more than 95 percent. A medical surgical mask is suitable for preventing blood, body fluid and splashes in invasive operation and respiratory infectious diseases transmitted by droplets, and has a bacteria filtering efficiency of not less than 95% and a non-oily particle filtering efficiency of not less than 30%.

According to the national Wei Jian Wei and Jian Wei, the technical guide for selecting and using the mask for preventing virus infection of different people:

the high-risk exposure personnel adopt a medical protective mask according to the protection suggestion, and when the medical protective mask is in shortage, the medical protective mask is replaced by a particulate protective mask meeting the standards of N95, KN95 and above;

higher risk exposure personnel, and the particulate matter protective mask with the standard of N95/KN95 and above is recommended for protection.

Moderate risk exposure, protection advocates medical surgical masks;

the protection of the lower risk exposure personnel suggests wearing disposable medical masks;

low risk exposure personnel, non-medical masks are suggested for protection;

to sum up, medical protective facial mask and medical surgery gauze mask are respiratory infectious virus's main protective articles, according to domestic practice, and the high risk exposes personnel, generally uses two-layer gauze mask protection, because the gauze mask area is big, and people's face has nose form arch, for preventing that the virus from getting into the mouth nose from gauze mask and facial contact site gap, need laminate the gauze mask in face hard, wear for a long time, cause facial wound and infection etc.. Because the medical protective mask can only be discarded after being used once in a high-risk exposure area, the number of medical protective masks consumed by high-risk exposure personnel every day is large. Because the two-layer mask is attached to the face by force, the resistance of the mask to air can cause the wearer to feel unsmooth breathing. The difficulty of breathing is aggravated after the patient with dyspnea wears the mask. Some people feel uncomfortable breathing after wearing the mask, so that the mouth is covered by the mask, the nose is exposed, and the protection effect of the mask is lost.
