Background technology
At present, China most of pathological anatomy chamber only is artificial contaminated area (dissection workplace), clear area (dressing cubicle that the shower function is arranged) of being divided into, and be not that technological means is distinguished contaminated area and clear area strictness, the dissection personnel do not have safe and effective individual protection equipment yet.Implement operation in the lower dissecting room of this protection level, virus is easy to be diffused into Semi-Contaminated Zone and clear area from the contaminated area by media such as personnel, dissection product, air, and the dissection personnel are also very easily by virus infections.
Summary of the invention
The objective of the invention is to set up an infectious disease sample pathological anatomy chamber integrated protection system.At the lower present situation of current China pathological anatomy chamber protection level, the present invention thoroughly breaks away from the original outmoded pattern of dissecting room, and the theory of employing system design proposes novel infectious disease sample pathological anatomy chamber integrated protection system.The present invention by air inlet system (II), clear area (16), shower room (17), certainly sterilize Airshower chamber (12), dissect prepare between (10), many positions wash and disinfectant house (9), certainly sterilize Airshower chamber (8), dissect keep in cold storage chamber (1), exhaust system (I) of workplace (18), sample and be connected to form integrated protection system successively.And, the pathological anatomy chamber is divided into: clear area (16), first-level buffer band---shower room (17) and sterilize certainly Airshower chamber (12), Semi-Contaminated Zone---dissect prepare between (10), level 2 buffering band---many positions wash and disinfectant house (9) and sterilize certainly Airshower chamber (8) and contaminated area-dissection workplace (18) and sample five functional areas (" three districts two are with ") such as chamber (1) that keep in cold storage according to instructions for use and possible pollution level.And by control advance, the mode of exhaust system air quantity, make the contaminated area---dissect workplace (18) and the sample chamber (1) that keeps in cold storage and locate negative pressure state all the time, the Semi-Contaminated Zone---(10) were in atmospheric pressure state between dissection was prepared, and clear area (16) are in barotropic state; Thereby guarantee that pollutant is strictly controlled within the zone of qualification, it can not spread to polluting little zone by heavy-polluted zone by air current flow.Between (10) transferring cabin (7) and superpressure exhaust valve (19) are being set between dissection workplace (18) and dissection preparation.(10) were furnished with personal protection equipment between dissection was prepared: breathing mask and impermeable protective clothing, protective glove, the personnel that dissect wear in the dissection process for sample, are strictly on guard against that pollutant touches personnel's health by respiratory tract and skin.Enter the decontamination sterilization that the personnel that dissect (10) between preparation will pass through strictness from dissecting workplace (18), the air that comprises the decontamination solution decontamination sterilization in many positions wash and disinfectant house (9) and the Airshower chamber (8) of sterilizing certainly blows drip washing and disappears, with prevent pollutant by personnel protection obey dissect workplace be diffused into dissect prepare between.Autopsy table is located in the bio-safety operating desk (6), prevents that pollutant from entering ambient air.The air current composition of dissecting operation room is carried out press-down type handle, the gas that contains pollutant is flowed downward as far as possible, reduce the virus concentration of personnel respiratory region; The strict shunting of the stream of people and logistics reduces the possibility that virus is brought into to the clear area.(10) are changed one's clothes to distinguish air circulation purifier (11) are set between dissection is prepared, and the contamination air in this zone that may enter further is purified.Dissecting workplace (18) when normally using, air draft blower fan (3) continuous firing of exhaust system is when dissecting operation room (18) when stopping using; The blower fan on duty (2) of exhaust system starts and continuous firing, pours in down a chimney to indoor with the virus that prevents to adhere on the duct wall, and prevents that the air in high pollution district from spreading to the clear area.
This guard system enters the processing of the air of dissection workplace (18) through combined type air intake filter (13) and air-supply negative ionization, and adopts press-down type air intake mode on air-supply is handled; Mainly adopted the measure of air coarse filtration and air-supply negative ionization.On air draft is handled,, just be discharged in the atmosphere from dissecting gas that workplace (18) discharges after the purified treatment of combined bio purifier (5).
Spread with periphery upward in order effectively to control pollutant, most of pollutant is controlled in certain scope, and consider that the easy to use of dissection personnel, the air-supply of dissecting room adopt ceiling to concentrate the mode of air-supply, the air draft of side wall both sides to make air-flow can form an approximate empty air curtain at a triangular space.Air outlet is located at the vertical direction of bio-safety operating desk (6), makes the respiratory region that directly is blown into the people through the outdoor air that purifies, and forms certain tangible pressure gas stream down in the respiratory region, reduces the possibility that pollutant enters people's expiratory system.
This guard system by control advance, the mode of air draft air quantity, make clear area (16) superpressure be not less than 60pa, (10) were in zero-pressure substantially between dissection was prepared, the negative pressure of dissecting workplace (18) is not less than-60pa, thereby make that the virus in the dissecting room is effectively isolated, all approach of blocking-up contamination.
Clear area (16) is the interim rest of participating in the dissection personnel and other staff's workplace, and personnel protection be simply to protect, and simple protective equipment such as can wear masks.(10) changed personnel's such as protective equipment and test data sheet workplace between dissection was prepared for the dissection personnel, and personnel should wear medical science and isolate clothes, wear gloves and the above mouth mask of N95, maybe can wear a gas mask.Implement during the dissection operation in dissecting workplace, personnel protection is the protection of highest level; Must outside wearing the medical protection clothes, wear impermeable protective clothing, wear special-purpose mask (mustn't wear masks in the mask) and rubber gloves.
Bring phenomenon into for fear of personnel, dissect between workplace (18) and dissection preparation and be provided with many positions wash and disinfectant house (9) and the Airshower chamber (8) of sterilizing certainly between (10), outer clothes such as the mask of sterilizing through decontamination, protective clothing, gloves are stayed in the sealing retracting device of dissecting (10) between preparation; Prevent that pollutant from entering clear area (16), shift to reduce the pollutant that causes because of flow of personnel to greatest extent.
Bring into aspect the control in logistics, be provided with article transferring cabin (7) between (10) between preparing dissecting workplace (18) and dissect, transferring cabin has the uviol lamp disinfectant measure in (7).This transferring cabin (7) only is used for transmitting article by (10) between dissect preparing to dissecting workplace (18), can not back transfer, stop the possibility that pollutant is brought in logistics into.Dissect between workplace (18) and the outdoor environment and be provided with transferring cabin, to satisfy the needs that article such as sample transmit.
