Exhaust device for negative pressure isolation ward

Abstract

The invention discloses an exhaust device for a negative pressure isolation ward. The exhaust device comprises an exhaust body and a plurality of telescopic corrugated pipes. The exhaust body comprises a box, an air outlet, a plurality of air inlets, an air outlet valve and air inlet valves, wherein the air outlet and the air inlets are formed in the box, the air outlet valve is arranged on the air outlet, the air inlet valves are arranged on the air inlets, and the air outlet is used for being communicated with an exhaust pipeline in the negative pressure isolation ward. One end of each telescopic corrugated pipe is communicated with the corresponding air inlet, and the other end of each telescopic corrugated pipe is used for being communicated with the portion, needing air exhaust, of the negative pressure isolation ward. According to the exhaust device, the exhaust body is communicated with the building exhaust pipeline in the negative pressure isolation ward, the air inlets of the box are connected with the external telescopic corrugated pipe air exhaust pipelines, and the air outlet valve and the air inlet valves are used for controlling opening and closing of the pipelines, so that the purposes of guiding the flow direction of air in the ward and increasing the air change speed by changing the positions of exhaust openings are achieved. The problem that according to an existing exhaust device on the market, the positions of air change ventilation openings cannot be scientifically and reasonably set is solved.

Description

technical field [0001] The invention relates to the technical field of air purification in a negative pressure isolation ward, in particular to an exhaust device for a negative pressure isolation ward. Background technique [0002] Recently, with the outbreak of the pneumonia epidemic, hospitals in various places have increased their demand for the construction of negative pressure wards that can control infectious diseases, and many such wards have been quickly completed and put into use. Due to urgent use requirements and convenient and fast installation, the location of ventilation ducts in many negative pressure wards during the construction process cannot fully serve the convenience of air diffusion and rapid convection discharge, but more consideration should be given to how to install them more quickly The overall piping system, which brings a series of problems in the process of gas replacement in the room. If the infectious disease pollution gas in the ward cannot ...

Problems solved by technology

Due to urgent use requirements and convenient and fast installation, the location of ventilation ducts in many negative pressure wards during the construction process cannot fully serve the convenience of air diffusion and rapid convection discharge, but more consideration should be given to how to install them more quickly Integral piping system, which brings about a series of problems in the process of gas replacement in the room

If the infectious disease pollution gas in the ward cannot be discharged in a reasonable and timely manner, it will be detrimental to the recovery of the patient, and even increase the risk of infection for the medical staff, and there are certain hidden dangers
