Description
Technical Field
The utility model relates to an operating room disinfection technical field specifically is a medical treatment air disinfection purifier for operating room convenient to installation.
Background
The air pressure in the operating room varies according to the cleanliness requirements of different areas (such as an operating room, a sterile preparation room, a hand brushing room, an anesthesia room and a surrounding clean area). Laminar flow operating rooms of different grades have different air cleanliness standards, for example, the U.S. Federal Standard 1000 is ≥ 0.5 μm dust per cubic foot of air, ≤ 1000 or ≤ 35 per liter of air. The standard of 10000 levels of laminar flow operating room is that the number of dust particles in each cubic foot of air is more than or equal to 0.5 mu m and is less than or equal to 10000 particles or is less than or equal to 350 particles in each liter of air. And so on. The main purpose of operating room ventilation is to remove the exhaust air from the various workshops; ensuring the fresh air quantity necessary for each workshop; removing dust and microorganisms; maintaining the necessary positive pressure in the chamber. The following two mechanical ventilation modes can meet the ventilation requirement of the operating room. The mechanical air supply and the mechanical air exhaust are combined: the ventilation mode can control the ventilation frequency, the ventilation volume and the indoor pressure, and has good ventilation effect. The mechanical air supply and the natural air exhaust are used together, the air exchange and the air exchange times of the ventilation mode are limited to a certain extent, and the ventilation effect is not as good as that of the former. The cleanliness class of an operating room is mainly distinguished by the number of dust particles and the number of biological particles in the air. Currently, the american space agency classification standard is most commonly used. The purification technology achieves the aim of sterility by controlling cleanliness through positive pressure purification of air supply flow. The purification technology can be divided into a turbulent flow system and a laminar flow system according to different air supply modes. (1) A turbulent flow system: the air supply outlet and the high-efficiency filter of the turbulent flow system are arranged on the ceiling, the air return inlet is arranged at the lower parts of two sides or one side of the wall surface, the filter and the air treatment are simple, the expansion is convenient, the manufacturing cost is low, the air exchange frequency is low, generally 10-50 times/h, vortex is easy to generate, pollution particles can be suspended and circularly flow in an indoor vortex area, pollution air flow is formed, and the indoor purification degree is reduced. The method is only suitable for 10000-1000000 grades of clean rooms in the NASA standard. (2) A laminar flow system; the laminar flow system utilizes the airflow with even distribution and proper flow velocity to bring particles and dust out of the operating room through the air return opening, does not generate vortex, does not have floating dust, improves the purification degree along with the increase of the air exchange times, and is suitable for the operating room of 100 grade in the standard of the American space navigation agency. But the filter has larger seal damage rate and higher manufacturing cost.
However, current air disinfection purifier for operating room does not set up and leads electrical pillar, can not simplify the circuit installation, can not reduce the professional operation process among the line connection process, thereby inconvenient staff inserts the air exhauster into external circuit, do not set up the installation framework, inconvenient staff installs the air exhauster on top air supply arrangement or bottom updraft ventilator, can not improve staff's installation effectiveness, inconvenient staff regularly cleans air exhauster and installation framework inside, do not set up the circulation gas case, inconvenient staff concentrates the collection to the inside circulation gas of operating room, can not practice thrift air disinfection purifier's use cost.
