Description

Air curtain type nursing bed and ambulance with same

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to an air curtain type nursing bed and an ambulance with the same.

Background

In ward areas, particularly respiratory infectious wards, the source of infection is primarily from within the patient's body, i.e., through the patient's breathing, coughing, sneezing, and the like. Under the existing medical care conditions, when handling a patient with a strong contagious nature, a negative pressure ward is usually set, namely: the air pressure in the ward is lower than the air pressure outside the ward to ensure that air polluted by the patient in the ward does not flow to the outside of the ward, thereby preventing medical staff from being infected by a large amount.

The negative pressure ward is utilized to isolate patients, and because the negative pressure ward usually has a larger space, airflow tissues are difficult to form, and medical staff still need to enter the negative pressure ward in the process of treating patients, so the risk of infection of the medical staff still exists.

When dealing with some sudden infectious diseases, such as SARS, Xinguan and the like, the construction period of the negative pressure ward is long, the cost is high, and the negative pressure ward can not be quickly applied to disease isolation and treatment.

Disclosure of Invention

In view of this, the present invention provides an air curtain type nursing bed, which can form an air curtain in the circumferential direction of a hospital bed by using an air flow, thereby playing a role of physical isolation.
