120 negative pressure ambulance what does it mean?
Negative pressure ambulance is the use of technical means, so that the air pressure inside the car is lower than the outside atmospheric pressure, so that the air in the free flow can only flow from the outside of the car to the car, after harmless treatment can also be discharged from the car air, in order to avoid the infection of more people. In the treatment and transfer of infectious diseases and other special diseases, the probability of cross-infection among medical personnel can be minimized.
The car is also equipped with a respirator, defibrillator, cardiac monitor and other full set of rescue equipment, and is equipped with ultraviolet disinfection lamps, central oxygen supply interface, etc., in the future can be in the ambulance to carry out debridement and suture surgery and cardiopulmonary resuscitation resuscitation, which is very difficult to imagine in the ordinary ambulance. Mainly used to rescue critically ill patients, infectious diseases and other special diseases.

Technical Requirements
National Ministry of Health's requirements for the hourly air change is 20 times, negative pressure value of 10Pa to 38Pa between the filter separation rate of 99.9%
Negative pressure ambulance patients cabin negative pressure refers to the relative pressure difference between the cabin and the outside atmosphere, mainly relying on the exhaust fan to the outside atmosphere to the active exhaust and sealing of the cabin to realize the treatment. Patient cabin air in the atmosphere before the discharge, generally by the high efficiency filtration, can effectively reduce the pathogenic microorganisms to the ambulance to the outside environment of the proliferation, pollution.
This method is only a physical isolation method, bacteria, viruses are intercepted on the surface of the high-efficiency filter, can not kill, ambulance should be used after the disinfection of the cabin.

What is a negative pressure vehicle
Negative pressure vehicle refers to:
Negative pressure vehicle's biggest feature is the negative pressure, in the rescue and transfer of infectious diseases and other special diseases can be minimized to reduce the chances of cross-infection among the medical staff, and the negative pressure can also be the air inside the vehicle for harmless treatment and then discharged to avoid more people Infected.
The car is also equipped with a respirator, defibrillator, cardiac monitor and a full set of rescue equipment, installed ultraviolet disinfection lamps, central oxygen supply interface, etc., the future of clear suture surgery and cardiopulmonary resuscitation and other salvage can be carried out in the ambulance, which is unimaginable in the ordinary ambulance. It is mainly used for the rescue of critical patients and infectious diseases and other special diseases.

Do you know "negative pressure ambulance"? What is the difference between a negative pressure ambulance and a normal ambulance?
The sudden outbreak of the epidemic has made masks, protective clothing, and disinfectant become in short supply, in fact, it is not only these that are in short supply, but also "negative pressure ambulance". Ambulances are very common, but for the "negative pressure ambulance" but few people know. What is a negative pressure ambulance? What is the difference between an ordinary ambulance and a "negative pressure ambulance"?
The difference between a negative pressure ambulance and an ordinary ambulance is the negative pressure. "Negative pressure ambulances are of a higher class than normal ambulances, but they are also based on normal ambulances. The "negative pressure ambulance" is equivalent to the ordinary ambulance with an isolation device, that is to say, the vehicle is completely isolated from the outside of the vehicle, so as to avoid patients with infectious diseases to spread the germs to the outside.
"Negative pressure ambulance" stretcher set up a special air recovery port, breath recovery port to the patient's exhaled gas extraction, and then filtered, sterilized and then discharged out of the car, thus avoiding the spread of germs in the air. The so-called negative pressure, the air in the compartment will be 10 to 30 pa lower than the air pressure. So even though the air in the compartment is contaminated by the patient, it will not leak out of the car and will not cause pollution of the air.
Another thing is that the air conditioning system inside the car is also different from the ordinary ambulance, which is also the key part of the negative pressure ambulance, the air conditioning filter sterilization function has strict requirements. The car will not only be equipped with ultraviolet disinfection lamps, negative pressure ambulance medical emergency equipment is also quite complete, compared to the ordinary ambulance is more complete. Many surgeries can be performed on negative pressure ambulances, while ordinary ambulances are not able to achieve such conditions.
Because of the suddenness of the epidemic, negative pressure ambulances have also become relatively scarce supplies, and there are already many car companies that have unconditionally donated negative pressure ambulances to hospitals around the world. For example, like Chery Automobile on the first day of the year emergency deployment of its Ruifengt special vehicles to resume overtime, the production of special negative pressure ambulances for patient rescue. At present, the production of negative pressure ambulance car companies are not many, Shanghai Datsun, Jiangling Motors, etc. have received the requirements of the relevant departments to request the production of negative pressure ambulance requirements.
Negative-pressure ambulances are suitable for the transportation of patients with highly contagious diseases, but also in the negative-pressure ambulance to carry out some surgery. And ordinary ambulances can not meet such requirements and standards. It is also because of the extremely high requirements, so the production of the car companies are only a few, and based on the special characteristics of the negative pressure ambulance, so it is unlikely to be mass production.
The difference between an ordinary ambulance and a negative-pressure ambulance is very great. Negative-pressure ambulances are uncommon because of their cost and use. Because of the special nature of this epidemic, so the negative pressure ambulance into people's eyes. And the ability to produce negative pressure ambulance car companies also open full power in the production, and some vehicles have been put into use, shows that our car companies do not mean to focus on the interests of the key moments, reflecting the social responsibility of the car companies. More than one production, then will reduce the chance of cross-infection, but also faster to win the war without smoke.

What is the difference between a negative pressure ambulance and an ordinary ambulance?
One, the facilities are different
1, negative pressure ambulance: the car is also equipped with a respirator, defibrillator, cardiac monitor and other full set of rescue equipment, installed ultraviolet disinfection lamps, central oxygen supply interface.
2, ordinary ambulance: the car also carries splints and brackets used to fix the patient's broken limbs, and to avoid the patient's neck and spine injury aggravation. The car is also equipped with oxygen, portable ventilators and defibrillators. Most ambulances also have patient monitors that can monitor a patient's pulse and breathing on the way to the emergency room.
Two, different features
1, negative pressure ambulance: the so-called negative pressure, is the use of technical means, so that the air pressure inside the car is lower than the outside atmospheric pressure, so the air in the free flow can only be outside the car to the car, and the negative pressure can be harmless treatment of the air inside the car after the discharge, to avoid more people infected, in the rescue and transportation of infectious diseases and other special diseases can be maximized to Reduce the chance of cross-infection of medical personnel.
2, ordinary ambulance: modern ambulances are more spacious inside, so that ambulance personnel have enough space to go to the hospital on the way to the patient rescue treatment. Modern ambulances also carry a large number of bandages and dressings inside, which can help stop bleeding, clean wounds and prevent infection.
Extended information
Technical requirements
National Ministry of Health requirements: 20 air changes per hour, the negative pressure value of -10Pa to -38Pa between the filtration separation rate of 99.9% of negative pressure ambulance patient cabin negative pressure refers to the cabin and the outside world between the relative pressure difference between the atmosphere, relying on the exhaust fan to the outside world to the atmosphere of the active exhaust and the sealing process of the cabin. Realization.
Patient cabin air in the atmosphere before discharge, generally filtered by a high-efficiency filter, can effectively reduce the patient microbial diffusion to the ambulance to the outside environment, pollution. This method is only a physical isolation method, bacteria, viruses are intercepted on the surface of the high-efficiency filter, can not kill, ambulances should be used after the disinfection for the cabin.

What is called Negative Pressure Ambulance
What is Negative Pressure Ambulance?
Negative-pressure ambulance, that is, protective ambulance, which is the biggest difference between ordinary ambulance is able to "negative pressure isolation", mainly used for major infectious disease safety isolation and transportation.
First of all, it has a piece of independent space, in this piece of space, it is necessary to complete the exchange of air inside and outside the car, which is required to be sterilized and then filtered, and then can be completed, and this piece of space we call it the negative pressure cabin, which has a good isolation, anticorrosive, ventilated, bacteria-resistant and other characteristics, so the negative-pressure cabin is safe and hygienic, and it is the most suitable for the transportation of infectious patients, it has good isolation, anti-corrosive, ventilation, bacteria-resistant and so on. The patient is the most appropriate, it can be watertight protection virus re-transmission.
The working principle of negative pressure ambulance
It is like, the upstream clean water flow downstream, the middle of a source of pollution, in order to ensure that the flow of water downstream clean and pollution-free, it is necessary to install a disinfection and filtration device at the source of pollution, this device is equivalent to negative pressure ambulance within the negative pressure device, which makes the car inside the pressure is lower than the car outside the atmospheric pressure, so that the air can only flow to the car outside the car, and will be the negative pressure ambulance, the air pressure is lower than the car outside the atmospheric pressure, so that the air can only flow to the car outside the car. It makes the air pressure inside the vehicle lower than the atmospheric pressure outside, so that the air can only flow from the vehicle to the vehicle, and the air inside the vehicle will be sterilized and discharged, so that a fixed air flow field area is formed inside the negative-pressure cabin, the air flows from the clean area to the infected source area, and the air pressure inside the negative-pressure cabin is between -10Pa~-120Pa, which makes the air flow with the smallest dead space and vortex flow.
In the vehicle airflow control, clean air enters the vehicle from above and is discharged from underneath the vehicle, which makes every effort to ensure that the air at the head position of the healthcare worker is clean and sterile, while the air at the patient's lying down place is contaminated and is discharged to the outside of the vehicle along with the exhaust and filtration devices, and the air that is discharged to the outside of the vehicle is filtered to the same clean and sterile air.
What is negative pressure ambulance
The so-called negative pressure, that is, the dust pressure is lower than the external atmospheric pressure, so the air in the free flow can only be outside the car to the car, the two before the negative pressure filtering device can also be down to the air inside the car after purification treatment, not to make the surrounding environment contaminated, and in the rescue and transportation of special infectious disease can be maximized to minimize the cross-infection of medical personnel. The company's products and services are also available in a wide range of colors and sizes.
Negative-pressure ambulance in the retention of the negative-pressure stretcher, ventilator, cardiac monitor, ultraviolet disinfection lamp equipment, plus the installation of negative-pressure purification system, the contaminated air inside the patient room by high-efficiency air filtration, through the centrifugal fan, there is a compartment bottom directly out of the car, the establishment of the relative compartment outside the car of the value of a certain negative pressure.
