Abstract

The invention provides a device for preventing air capacity glue from diffusing during expectoration of a COVID-19 patient. The device comprises a front mask, protective high-elasticity cloth and an opening-binding garbage bag. The front mask is an arc-shaped transparent rectangular piece, an arc-shaped forehead pad is arranged on the inner side of the top edge of the front mask, the two ends of the arc-shaped forehead pad are connected through an elastic fixing band, the two ends of the top edge of the front mask are rotationally connected with the two ends of the arc-shaped forehead pad through rotating shafts respectively, movable rods are symmetrically arranged outside the two ends of the front mask, and the upper ends of the movable rods are rotationally connected with the rotating shafts. A chest abutting rod is connected between the lower ends of the two movable rods, and a hook is arranged in the middle of the front side of the chest abutting rod. The protective high-elastic cloth is of a cylindrical structure; the opening-binding garbage bag comprises a bag body and hanging lugs arranged on the top edge of the bag body, and the hanging lugs are hooked on the hooks in a matched mode. According to the invention, aerosol generated during expectoration of the COVID-19 patient can be effectively prevented from diffusing, medical personnel are protected, and subsequent spitting of the COVID-19 patient is facilitated.

Description

technical field [0001] The invention relates to the technical field of preventing aerosol diffusion, in particular to a device for preventing the aerosol from spreading when a patient with a new crown coughs up sputum. Background technique [0002] Severe or critical patients with new coronary pneumonia often have dyspnea and / or hypoxemia, and pathology shows that mucus, mucus plugs and other respiratory secretions are retained in the alveolar cavity and bronchial cavity. Therefore, it is very important to enhance the cough and expectoration ability of patients with new coronary pneumonia. [0003] At present, it is known that in addition to direct contact and droplet transmission, SARS-CoV-2 still has the risk of aerosol transmission, that is, in a limited space, the virus flows through the air, enters the human lungs from the respiratory tract, and then causes infection. The main component of virus aerosol is biological particles, which have a very small diameter, only 0....
