Description
Technical field
This patent proposes a kind of multiparameter wireless warning system for real time monitoring suitable for clean operating room air environment,
Belong to Heating,Ventilating and Air Conditioning and pollutant catabolic gene field.
Background technology
Clean operating room is the special area that sufferer receives surgical operation therapy.The clean environment control of operating room is ineffective,
Surgical site infection can be triggered.Surgical site infection can all cause very big harm to patient, hospital and society.China at present
Surgical site infection has accounted for the 3rd of hospital infection.
The air purity for keeping operating room indoor environment is one of important measures of infection control.It is kept in operating room good
Good air purity can not only reduce the risk of surgical site infection, reduce the probability that the postsurgery symptoms such as septicemia occur, also
The rehabilitation of post-operative patient can be may advantageously facilitate.For this purpose, authorities of hospital, school, design side, Construction Party and operation side are all
Pay much attention to the Surgery environment cleanliness situation of hospital.However, at present in the operating room inspection standards of completed project of our countries, though
Three kinds of acceptance phases, i.e. empty state, static state and dynamic are so referred to, but actual conditions are when the air-conditioning system of clean operation department is pacified
When installing complete, the mode usually only with empty state or static state carries out the examination of grade of cleanliness.It is pointed out that empty state
With all exist in operating room during static state without medical staff and patient, and when empty state not only with the presence of medical staff and patient,
Doctor performed the operation, nurse is in touring walk process, can all generate substantial amounts of pollutant；In addition personnel and equipment itself
Heat production, the air current composition originally designed for interior may all damage, so as to be further exacerbated by the evil of indoor air environment
Change.Still further aspect, when doctor is during normal surgical, school is unwilling also to disagree any third party to operating room air
Cleaniliness classs is measured into Mobile state, because being afraid of that this process can bring the uncertain source of infection, improves surgical site infection
Probability.In order to understand the quality of air environment of Surgery reality, the medical expert of nosocomial infection section simply stops in operation
Gap carries out the sampling of microorganism, including sedimentation bacteria concentration and the bacteria concentration that swims.Settling bacteria and the flcating germ measurement used at present
In method, it is necessary to sample is carried out with constant incubator 48 it is small when culture.However such sampling cannot really reflect
Go out the grade of cleanliness situation during actual operation.
Still further aspect, when carrying out final acceptance of construction to clean operating room, the mode for measuring humiture mainly uses hand-held
Hygrothermograph measures.Handheld instrument response is relatively slow, and influence of the survey crew to environmental parameter is very big, causes error
Larger, promptness is also inadequate, it is impossible to the variation of reaction indoor temperature and humidity promptly and accurately.In large-scale operating room, space is larger,
Requirement to house moss bacterium is very high, and suitable humiture is exactly the necessary condition of bacterial reproduction.
In order to reflect the quality of air environment in clean operation room in time, it is necessary to invent a kind of clean operating room dynamic ring
The real time on-line monitoring alarm system in border.
A kind of Chinese utility model patent " toilet's dust particle online monitoring system " (application number：
CN201120334176.2), power supply adaptor is changed to photocell, by being wirelessly transferred and reception saves wiring link, kept away
Exempt to pollute caused by the organosilicon of cable surface.Photocell converts light energy into electric energy, with the presence of personnel and equipment in toilet
And movement, it can shut out the light, indoor light may be caused to be unevenly distributed or even electricity shortage.Chinese utility model patent
" clean operating room on-line monitoring dust system " (application number：CN201420694567.9), surveyed by multiple photoelectric conversion devices
Dust content in the air at multiple positions is obtained, which passes sequentially through data acquisition controller, interchanger, router, wide area
Net is connected with ether long-range control host machine, realizes the content of dust in Remote Real-time Monitoring air.
But it does not account for existing and walking about, the effect of human body Thermal plume in clean operating room indoor occupant in above-mentioned patent
Under, the influence to air purity does not also monitor microorganism in real time.It is therefore desirable to toilet's multi-parameter is carried out
Monitoring in real time is realized the cleanliness factor environment and thermal and humidity environment of clean operating room under dynamic condition, is provided for medical staff and patient
On the basis of thermally comfortable environment, it is ensured that operative site grade of cleanliness, so as to reduce the risk of surgical site infection.
The content of the invention
Technical problem：The present invention relates to a kind of multiparameter wireless suitable for clean operating room air environment to monitor report in real time
Alert system specifically includes humiture, wind speed, oxygen, particulate matter, carbon dioxide and the multiple spot of microorganism real-time radio monitoring report
It is alert.
Technical solution：The present invention discloses a kind of multi-parameter multipoint wireless real-time monitoring alarming system suitable for clean operating room
System, the system are mainly made of data acquisition unit, ZigBee wireless routings, executing agency and host computer.The data acquisition
Unit includes Temperature Humidity Sensor, air velocity transducer, oxygen sensor, particulate matter sensors, carbon dioxide sensor, microorganism
Sensor, infrared sensor of the human body, battery, sound-light alarm, single-chip microprocessor MCU and ZigBee wireless modules composition.
The system can monitor the temperature of clean operating room room air in real time not on the basis of normal surgical process is disturbed
Humidity, wind speed, oxygen, particulate matter, carbon dioxide and microorganism concn.When some concentration over-standard, which can be timely
It alarms and timely feedbacks and be adjusted to central air conditioner system, to meet the thermal comfort of indoor medical staff and patient, medical mistake
The cleaniliness classs of journey.
It should be appreciated that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
Advantageous effect：
The beneficial effects of the invention are as follows：
1st, the measurement parameter of existing toilet's technology is few, wiring trouble, the present invention provide a kind of multi-parameter, in time efficiently,
Precisely convenient, economic quick, comprehensive good multiparameter wireless real-time monitoring and alarming.
2nd, measurement parameter of the present invention is more, can measure humiture, wind speed, oxygen content, particle concentration, carbon dioxide simultaneously
Content, human body infrared and microorganism concn, multi-parameter real-time measurement.Air purity can not only be measured, and can be obtained
How indoor multi-parameter influences air purity.
3rd, the present invention realizes wireless transmission.Measuring humiture, wind speed, oxygen content, particle concentration, carbon dioxide
