Air curtain system and isolating protective device

Abstract

The invention provides an air curtain system. The air curtain system comprises an air suction module, a draught fan module, a disinfection and filter module, an air outlet module and an air storage box. An inlet of the draught fan module communicates with the air suction module. An outlet of the draught fan module communicates with the air outlet module. The air storage box is arranged between thedraught fan module and the air outlet module. The disinfection and filter module is arranged between the air storage box and the draught fan module or between the air suction module and the draught fan module. Every two adjacent modules communicate through an airflow channel. On the basis of the structure, it can be ensured that the air outlet module continuously and evenly blows an air curtain with enough pressure out through arrangement of the air storage box, it is ensured that a respiratory airflow propagation path between people is completely cut off so as to completely eliminate the risks of spreading of germs and cross infection; and in addition, the invention further provides an isolating protective device, because the isolating protective device adopts the air curtain system, theair curtain with the enough pressure can be continuously and evenly blown out as well, and the cut-off effect is excellent.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an air curtain system and an isolation protection device. Background technique [0002] In the 21st century, when the ecological environment is changing rapidly, there are many kinds of viruses or bacteria with infectious diseases, such as SARS, tuberculosis, meningitis, cerebrospinal meningitis, chickenpox, measles, German measles, influenza, etc. The major threat of the virus has forced human beings to pay more attention to the potentially dangerous germs that are carried and transmitted through air or droplets. Therefore, in hospitals or clinics, preventing the spread of germs and cross-infection is an extremely important preventive work, and patients with infectious germs are the most important objects of protection in hospitals and clinics, which is the top priority. [0003] At present, some researchers have designed an isolation protective device with isolation ...
