2019 novel coronavirus (2019-nCoV), named by the world health organization on 1, 12 months in 2020. Coronaviruses are a large family of viruses known to cause the common cold and more serious diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The novel coronavirus is a new strain of coronavirus that has not been previously discovered in humans.

The new coronavirus causes pneumonia, but it is not a terrible place, and it causes panic because it is transmissible. Today, where social mobility is very high, its presence has led to a large number of infections in the population.

Another important reason for its fear is because it is a new emerging virus. In fact, coronavirus is ubiquitous in nature, and only people have immunity to coronavirus, so that the coronavirus does not cause large-scale illness. However, this time a new coronavirus was developed, which was not treated with specific drugs for the moment. Therefore, we now see that the virus is very virulent.

After receiving the information for asking for help from the patient, a medical facility such as a hospital may arrange 120 an ambulance to the patient's home to receive the patient. Because of the human transmission characteristic of the novel coronavirus, the negative pressure ambulance is particularly produced during the new coronavirus epidemic period of 2020, and the secondary infection of rescued patients is effectively prevented.

However, the production of the negative pressure ambulance requires time and the cost of purchasing the negative pressure ambulance is also high. Especially, the device belongs to idle storage equipment after overcoming the epidemic situation of the novel coronavirus, and wastes medical resources.
