Description

Portable tool for monitoring air disinfection effect and ultraviolet lamp irradiation intensity

Technical Field

The utility model belongs to the technical field of air disinfection effect and ultraviolet lamp irradiation intensity monitoring, concretely relates to a portable instrument that is used for air disinfection effect and ultraviolet lamp irradiation intensity monitoring.

Background

According to the disinfection and sanitation standard of hospitals (GB 1598-2012), each department of the hospital needs to monitor the disinfection effect of air, the radiation intensity of ultraviolet lamps in use and the like on time.

The air disinfection effect is monitored by a flat plate exposure method. Rooms without clean technology to purify air: indoor area is less than or equal to 30m ² Setting three sampling points of an inner diagonal, a middle diagonal and an outer diagonal, wherein the distance between the inner point and the outer point is 1m from the wall; indoor area is more than 30m ² The method is characterized in that five sampling points are arranged at four corners and the center, the distribution positions of the four corners are 1m away from a wall, and the sampling height is 0.8 m-1.5 m away from the ground (GB1598-2012 hospital disinfection standard). Cleaning a room: the sampling points are arranged on the ground or at any height of 0.8m or less (GB 50333-2013 building technical Specification of clean operating department of Hospital). Placing each sampling point on a common nutrient agar culture dish (phi 90 mm), opening a culture dish cover during sampling, buckling the culture dish cover beside the culture dish, covering the culture dish cover after exposing for a specified time (the I-class environment is exposed for 30min, the II-class environment is exposed for 15min, and the III-class and IV-class environments are exposed for 5 min), and timely inspecting. The traditional operation method is to stack and place culture dishes by using equipment and articles in a sampling room, so that the heights are inconsistent, the positions are not determined, the heights and intervals required by monitoring cannot be accurately achieved, the monitoring result is influenced, and great difficulty is brought to medical staff in operation. After the flat plate is opened, a sampling person often forgets time while working for processing other work, so that the exposure time is inaccurate, and the monitoring result is influenced.

The radiation intensity of the ultraviolet lamp is generally monitored by a chemical indicator card method, after the ultraviolet lamp is started for 5min, the indicator card is placed below the ultraviolet lamp at a vertical distance of one meter, the side with patterns faces upwards, the irradiation is carried out for 1 min, the color of the color block of the indicator card is observed, and the color block is compared with the color block of the standard. In the traditional operation, when an ultraviolet lamp is monitored, a rope with the length of 1m is used before monitoring, one end of the rope is tied on an ultraviolet lamp tube, the other end of the rope is tied with an ultraviolet lamp irradiation intensity chemical indicator card, the indicator card cannot be accurately placed flatly and can not be directly irradiated on the ultraviolet lamp, and the monitoring effect is influenced.
