Convection transfer system

Abstract

The invention discloses a convection transfer system. The convection transfer system comprises a convection helmet, wherein the convection helmet comprises a bottom cover and a buckling cover which are hinged together; and a gas collecting device, wherein the gas collecting device is mounted at the bottom of a transfer stretcher and connected with the bottom cover through a gas guide pipe. According to the convection transfer system, danger and suffering of a patient during negative-pressure transportation are relieved, the convection helmet is adopted to relatively seal local parts above a neck of a patient, a whole body of the patient is sealed, fresh air enters the convection helmet through a gap between the convection helmet and the patient and an air inlet, and gas exhaled by the patient and the fresh air are mixed and then collected by the gas collecting device, so that bacteria and viruses are collected into a specified sealed container; and an isolated patient can be free of psychological disorders, and normal workers can be protected from being affected.

Description

technical field [0001] The invention relates to the technical field of infectious disease treatment and transfer, and more specifically relates to a convective transfer system. Background technique [0002] Respiratory tract infectious diseases are spread through the air by pathogenic pathogens that cause healthy people who inhale or come into contact with these pathogens to be infected and become ill, thus causing the spread of infectious diseases and often causing serious health and social problems; currently People have developed positive pressure biological protective suits and positive pressure biological protective hoods to protect rescuers, medical staff and researchers who are exposed to severe infectious diseases, but how to prevent people infected with severe infectious diseases from releasing strong pathogens into the environment? safe transfer is very important.

Problems solved by technology

[0003] Patent ZL201110082388.0 discloses a negative pressure isolation inflatable stretcher for infectious patients, which describes a closed cabin with an arched airbag hatch and an airbag bilge formed by waterproof zippers. However, during the treatment and transfer process, since the body is in a closed space, it is difficult for medical staff to treat and prevent emergencies;

[0004] In addition, negative pressure ambulances are commonly used in the transfer process. The negative pressure purification system and air inlet and outlet are equipped on the vehicle to form a relative negative pressure state in the ambulance cabin, so that the air in the cabin can form a relatively stable airflow without any direction. External diffusion to reduce the cross-contamination source of medical personnel and patients in the process of transportation and transfer, but the air in the cabin needs to pass through the exhaust outlet uniformly, and then be discharged out of the vehicle after efficient sterilization and purification; while the space in the ambulance cabin of negative pressure ambulances is generally Reaching 6-8m3, the space is very large, so the relative air pressure can only reach about -30pa, and the relative efficiency is very low. Through a large number of smoke tests, when the relative negative pressure in the ambulance cabin is about -30pa, the exhaust port of the negative pressure purification system It is difficult to form a relatively stable airflow around; it is difficult to ensure that all the air exhaled by the patient's mouth is drawn into the exhaust port of the negative pressure purification system in time

Especially when the patient sneezes or shakes the head, the air in the ambulance cabin is easily polluted, which may cause cross-infection between doctors and patients, and there will be people walking around in the ambulance cabin, making the air flow in the cabin more unstable and increasing. possibility of infection
