Description

Negative pressure disinfection protection ambulance

Technical Field

The invention relates to the field of medical equipment, in particular to a negative pressure disinfection protection ambulance.

Background

The ambulance is a special vehicle for rescuing and transporting patients, when the patients with infectious diseases, particularly the patients with respiratory diseases are transported, the patients often carry viruses and infectious microorganisms, at the moment, the safety of the casual medical care personnel needs to be ensured, meanwhile, the hidden danger of secondary propagation which is possibly formed is carried by the patients is blocked, therefore, a closed negative pressure environment needs to be arranged inside a carriage, the air pressure in the carriage is smaller than the outside, the patients need to be isolated in the transportation process, aerosol is easy to generate due to the space limitation of the ambulance, and the key for controlling the virus propagation is timely and effectively to capture and separate the aerosol.

The medical staff seat is provided with the positive pressure fresh air cover, so that the safety of the medical staff is ensured, and the medical staff is prevented from being infected when medical intervention is carried out on a patient. The waste water and the waste gas generated in the traditional ambulance during the transportation process are not well collected, disinfected and sterilized, and the environment of the ambulance during the walking process is polluted.

Chinese patent 'CN 1806785A' is a negative pressure ambulance for preventing cross infection of doctors and patients, which comprises a body, a large sealing plate square cabin connected with a chassis of the body, and a control device, wherein the large sealing plate square cabin consists of a front functional cabin and a rear medical cabin; the front functional cabin is an air flow direction control unit, the rear medical cabin comprises an air inlet chamber in the cabin, an air outlet chamber in the cabin, and a medical device is also arranged in the cabin; a sealable cabin door is arranged on the rear medical cabin; the air inlet chamber in the back medical cabin is communicated with the mixed air chamber in the front functional cabin, and the air exhaust chamber in the back medical cabin is communicated with the air filtering and disinfecting chamber in the front functional cabin. Although the structure controls the air pressure, the structure lacks the control on the air pressure difference inside the cabin and the protection of medical care personnel, and simultaneously does not carry out timely isolation, blocking and disinfection on viruses possibly carried by patients, so that the infection possibility of personnel in a carriage exists, and the waste gas and the waste water are not disinfected and cleaned, so the improvement is needed.

The Chinese Disinfection science impurity 2012, volume 29, phase 12, has a paper "air microorganism aerosol enrichment, detection and air disinfection technology research progress" which indicates that the killing rate of the plasma disinfection method to bacteria is 98.9%. The plasma disinfection mainly depends on active oxidation substances such as active oxygen atoms, molecules, free radicals and the like generated in the ionization process to destroy the protein components on the cell membrane surface of microorganisms, thereby achieving the effects of sterilization and air purification.
