Problems solved by technology

However, recent medical research data indicate that uniflow ventilated operating rooms have a higher risk of postoperative infection
[0003] In addition, the transformation of ventilation facilities in medical facilities such as operating rooms often involves relatively large reconstruction costs, such as the need to replace ventilation ducts, ventilation and purification facilities, etc., and such replacements generally require repairing and redecorating the building itself. , thereby increasing the cost of reconstruction, which is not conducive to the replacement of ventilation facilities

Embodiment Construction

[0027] Figure 1A and 1B A bottom view and a cross-sectional view of the weak turbulence centralized air supply device 100 according to the present invention are respectively shown. It should be pointed out that although the present invention is described with an operating room as an example, those skilled in the art can understand that this is only exemplary, and the present invention can also be used in other applications, such as general wards, neonatal wards , intensive care unit, central supply room and other places with similar high requirements on air quality. Here, it should also be pointed out that the weak turbulence used in the present invention is an objective parameter, which refers to the degree of turbulence (or degree of turbulence, that is, the measure of the fluctuation of the airflow velocity relative to the average value, i.e. the relative standard deviation) 5% to 20%. In addition, turbulent flow 20% is turbulent flow or turbulent flow (see German standa...

Abstract

The invention relates to a fabricated type weak turbulent flow centralized air supply device. The fabricated type weak turbulent flow centralized air supply device is provided with an air inlet arranged to guide airflow into a centralized air supply device body, a plurality of air supply modules, and a fixing device arranged to fix the weak turbulent flow centralized air supply device body to thetop wall of a medical facility. Each air supply module comprises a static pressure space, a filter layer, a flow homogenizing film and a flow diffusing plate, wherein the thickness of the filter layerand / or the folding pitch of filter paper of the filter layer are / is set for making guided-in airflow enter the medical facility in a weak turbulent flow form through a fence structure with the heightof 450 mm. Through the fabricated type weak turbulent flow centralized air supply device, the postoperative infection risk can be effectively reduced with the low reconstruction cost; and modular construction of the medical facility can be achieved, and quality guaranteeing, cost reducing and efficiency improving are facilitated.

Description

technical field [0001] The present invention generally relates to the field of medical ventilation facilities, in particular to an assembled weak turbulent centralized air supply device and an assembled weak turbulent concentrated air supply device. Background technique [0002] At present, mainstream medical ventilation facilities use unidirectional flow clean technology. Unidirectional flow, also known as "laminar flow", refers to the airflow passing through the air purification device or clean area in the same direction and with roughly parallel streamlines. The judgment condition of unidirectional flow is: the deviation between the streamline passing through the clean area and the ideal straight line does not exceed 14°. However, recent medical research data show that operating rooms with one-way ventilation have a higher risk of postoperative infection. [0003] In addition, the transformation of ventilation facilities in medical facilities such as operating rooms oft...
