Steady-state replacement flow clean cabin

Abstract

The invention discloses a steady-state replacement flow clean cabin and relates to the technical field of medical equipment, in particular to a steady-state replacement flow clean cabin. The steady-state replacement flow clean cabin comprises a cabin body, a fresh air supply unit, an air supply unit, an air exhaust unit and an air return virus elimination cycle unit, wherein a cabin body plate material adopts a one-time foaming polyurethane sandwich color plate which has good heat insulation and damp-proof performance, a framework adopts an aluminum alloy cold resistant bridge special sectional material, the sealing effect is good, and the whole cabin body has the characteristic of being convenient to disassemble; the fresh air supply system has the dual functions of sterilization and dustfiltration, and the effect that the number of fine particles in air entering the cabin from the outside is almost zero can be achieved; an air disinfecting and purifying device is used in the air exhaust unit, the fact that exhausted air is almost sterile and nontoxic is finally realized, and the outdoor environment is subjected to little influence; and the air return virus elimination cycle unitis used for cutting off exhaust air when no pollution source exists in the cabin, air in the cabin circularly runs, and electricity, energy and consumables are saved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a steady-state replacement flow clean cabin. Background technique [0002] Clean technology is also called clean cabin technology. In addition to meeting the conventional requirements such as temperature and humidity in the air conditioner room, the clean cabin also needs to pass various engineering and technical facilities and strict management to ensure the pressure and particle concentration in the clean cabin. It is also controlled within a certain range. [0003] As we know, all kinds of viruses and bacteria are invading human beings every moment on the earth we live on. In order to remove indoor pathogenic substances, such as bacteria, viruses, and fungi, ultraviolet light is generally used to disinfect and sterilize indoor spaces. Ultraviolet light is commonly used in operating rooms, dispensing rooms, etc. in hospitals. In the prior art, in order to fill the ...

AI Technical Summary

Problems solved by technology

However, although the medical staff are simply disinfected before entering the operating room, as the operation proceeds, the sweat of the medical staff and the body debris separated from the body will bring the bacteria and viruses on the medical staff into the operating room In the air, it is very easy to cause infection of patients during the operation

In addition, when the sterilized and sterilized clean air is usually at room temperature, the clean air usually performs Brownian motion in the operating room after entering the operating room, so that the clean air will quickly spread to all corners of the operating room, and the same as the original The air in the operating room is mixed. When the original air contains bacteria or viruses, the clean air will have a weak effect on maintaining a sterile environment in the operating room.
