Vehicle-mounted negative pressure gas collection and disinfection system

Abstract

The present invention discloses a vehicle-mounted negative pressure gas collection and disinfection system. The system comprises a transfer trolley; the transfer trolley is provided with a stretcher and a chamber for placing the stretcher; the stretcher is provided with a gas collection hood; the gas collection hood is located above the head end of the stretcher; the gas collection hood is of a hollow structure; the inner wall of the gas collection hood is provided with gas holes; the gas collection hood is provided with a gas guide pipe communicating with the gas collection hood; a gas inletpipeline of the transfer trolley is provided with a branch pipe; and the tail end of the branch pipe extends into the chamber and can communicate with the gas guide pipe. The system is suitable for manual transfer of respiratory tract infectious disease patients, the infection of the public environment is reduced, the infection risk of transfer personnel along with the trolley is lowered, the mental stress is relieved, the structure is convenient and quick to mount, accessory materials are easy to obtain, and the system is particularly suitable for use in the epidemic outbreak period.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a vehicle-mounted negative pressure gas collection disinfection system. Background technique [0002] The widespread spread of respiratory infectious diseases has an indelible impact on patients and also causes harm to medical staff. Infected patients are usually transported by emergency negative pressure vehicles. Emergency negative pressure ambulances have a small space and good negative pressure effects , but the patient and the emergency medical staff live in the same space, and the air exhaled by the patient may stay in the shared space for a long time, or may pass through a flight distance of about two meters before entering the air intake in the car. Or construction reasons, the air vortex is caused, and it is easy to form aerosol, which greatly increases the infection risk of medical staff, and secondary or cross-infection events are very easy to occur. Therefore, in orde...

[0002] The widespread spread of respiratory infectious diseases has an indelible impact on patients and also causes harm to medical staff. Infected patients are usually transported by emergency negative pressure vehicles. Emergency negative pressure ambulances have a small space and good negative pressure effects , but the patient and the emergency medical staff live in the same space, and the air exhaled by the patient may stay in the shared space for a long time, or may pass through a flight distance of about two meters before entering the air intake in the car. Or construction reasons, the air vortex is caused, and it is easy to form aerosols, which greatly increases the infection risk of medical staff and is very prone to secondary or cross-infection events. Therefore, in order to avoid the above situation, the source of infection must be controlled
