Novel exhausting device

Abstract

The invention discloses a novel exhausting device which comprises a body, a ventilating cover and melt-blown cloth. The body is provided with an air passing cavity. The air passing cavity is providedwith a wind inlet and a wind outlet. The wind outlet is used for communicating with air extracting equipment at the outer end. The ventilating cover is detachably arranged on the body in a matched manner and covers the wind inlet. The ventilating cover is provided with a plurality of ventilating holes. The melt-blown cloth is matched between the air passing cavity and the ventilating cover. According to the novel exhausting device, the exhausting structure which is simple and low in cost can be achieved, by means of cooperation of the air extracting equipment such as an air extracting pump andan air blower at the outer end, expiration of a single patient can be extracted, cross infection in a ward is avoided, and the novel exhausting device is applicable to improvement of an existing hospital ventilating system or use on some temporary occasions. The detachable structure is adopted between the ventilating cover and the body, the melt-blown cloth inside can be replaced conveniently ina timing manner, and thus the filtering effect is ensured.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a novel exhaust device. Background technique [0002] Air is one of the most direct vectors of respiratory infectious diseases, causing respiratory infectious diseases to spread very quickly and widely. With the continuous outbreak of the new crown epidemic, people are paying more and more attention to the prevention of respiratory infectious diseases, and they are wearing masks spontaneously or according to policies. For patients with infectious diseases, due to the limitations of the ward environment, there are usually 3-5 patients in a ward during the treatment in the hospital. A simple sneeze or cough may lead to the rapid spread of the virus and cause cross-infection , making the condition more serious. [0003] The root of solving the above problems is to take good ventilation measures. However, for some old or small hospitals, the design of the ventilation sy...

Problems solved by technology

[0003] The root of solving the above problems is to take good ventilation measures. However, for some old or small hospitals, the design of the ventilation system is not perfect when they are established, and a good ventilation effect cannot be achieved.

To achieve good ventilation at this stage, it takes a lot of cost to build and improve ventilation ducts
