Isolation and killing system for respiratory system infectious disease

Abstract

The invention relates to the field of medical machinery, and in particular to a isolation and killing system for respiratory system infectious disease. The isolation and killing system comprises an isolation device that closes snout and facial region between nasal bridge and mandible. The isolation device includes a nasal bridge holder and a mandible holder, wherein an upper bracket extending downward, that is, in the direction of the mandible holder can be provided under the nasal bridge holder, and a lower bracket extending upward, that is, in the direction of the nasal bridge can be provided above the mandible holder. An air filtering device is provided between the nasal bridge holder and the mandible holder, and the air filtering device covers the outside of the upper bracket and the lower bracket, so that the inner sides of the upper bracket and the lower bracket form a hollow area. The nasal bridge holder, the upper bracket, the lower bracket, the mandible holder and the air filtering device are integrated with each other to form an isolation device that matches the contours of face of a person. The isolation and killing system can completely prevent isolation of infection source and block route of transmission. The system has simple structure, few materials, low cost, easy to wear and unload.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a system for isolating and killing respiratory infectious diseases, which is mainly used for isolating and blocking the transmission of people (patients, infectious sources) with respiratory system infection in the process of diagnosis, treatment and research, or Prevent passive transmission of susceptible groups (medical staff, family members of infected persons, close contacts, etc.) who are exposed to respiratory infections and need to take isolation and blocking measures, and block the microorganisms in the process of transmission in the disinfectant in the disinfection device Kill, prevent re-inhalation into the lungs or release into the air. Background technique [0002] Respiratory system infectious diseases (such as influenza, pneumonia, tuberculosis, SARS, new coronary pneumonia, etc.) are common and frequently-occurring diseases. Regardless of time, sea...

Problems solved by technology

However, the tightness of masks and face shields is inaccurate, and breathing gas leaks in many places. During the process of opening and closing the mouth during speaking, the tightness of the mask is often shifted and the tightness is even worse.

Patients seldom wear protective clothing, but medical staff wear protective clothing in popular seasons, which have poor permeability, poor comfort, complicated putting on and taking off, time-consuming and expensive

That is to say, the principle of prevention and treatment of respiratory infectious diseases has repeatedly been proved to be correct, but the specific measures are not in place, and the key links have not been controlled, that is, the thorough control of the source of infection and the way of transmission

The more serious problem is that most of the gas with pathogenic microorganisms exhaled by patients is not discharged into the disinfectant solution after exhalation, but directly discharged into the living, living or hospitalized space, and such spaces are often difficult to thoroughly disinfect and sterilize
