Detail structure and maintenance of purification workbench
The power supply of the cleaning table is usually three-phase four-wire system, in which there is a 10-wire, connected to the machine shell, should be firmly connected to the ground, the other three lines are phase lines, the operating voltage is 380V. There is a certain sequence in the three-wire access circuit, such as the wrong connection of the wire, the wind turning, when the sound is normal or slightly abnormal, clean the front of the table can be used alcohol lamp flame investigation dynamic, not long-term test, should be timely cut off power supply, just any two phase of the wire head alternating position and then connected, you can be anywhere. Reason. If the three-phase line is only connected to two phases, or if one of the three phases is not in good contact, the sound of the machine is very abnormal, and the power supply should be stopped immediately and carefully overhauled, otherwise the motor will be burned. These knowledge should be explained clearly to the operators at the beginning of the use of the cleaning table to eliminate accidents and losses that should not be caused.
The air inlet of the cleaning operation table is under the reverse or positive side. There is a general foam plastic sheet or non-woven cloth in the metal mesh cover to obstruct large particles of dust. It should be inspected and dismantled frequently. If foam plastic is found to be aging, it should be replaced in time. In addition to the air intake, if there are air leakage pores, should be plugged tightly, such as adhesive tape, plugging cotton, adhesive paper, etc. Super filters can also be replaced by super filters in the metal mesh cover on the front of the workbench. New filters can be replaced if the dust is blocked and the wind speed decreases due to long service life and the sterility can not be ensured.
The length of service life is related to the cleanliness of the air. In temperate zones, purification stations can be used in general laboratories, but in tropical or subtropical zones, where the atmosphere contains high levels of pollen or dust, purification stations should be placed in better indoor use with double doors. Under no circumstances should the air inlet hood of the cleaning table be directed against an open door or window to avoid affecting the service life of the filter.
无菌室应定时用７０％酒精或０．５％苯酚喷雾降尘和消毒，用２％新洁尔灭抹拭台面和用具７０％酒精也可 ，用福尔马林４０％甲醛 加少数高锰酸钾定时密闭熏蒸，合作紫外线灭菌灯每次打开１５分钟以上 等等消毒灭菌手法，以使无菌室常常坚持高度的无菌状况。接种箱内部也应装有紫外线灯，运用前开灯１５分钟以上照耀灭菌，但但凡照耀不到之处仍是有菌的。在紫外线灯打开时刻较长时，可激起空气中的氧分子缔组成臭氧分子，这种气体成分有很强的杀菌作用，能够对紫外线没有直接照到的旮旯发生灭菌作用。由于臭氧有碍健康，在进入操作之前应先关掉紫外线灯，关后十多分钟即可入内。
Asepsis room should regularly use 70% alcohol or 0.5% phenol spray dust and disinfection, with 2% new gerune wipe the table and utensils, 70% alcohol can also be used, formalin 40% formaldehyde plus a small number of Potassium Permanganate regularly sealed fumigation, cooperate with ultraviolet sterilization lamp to open for 15 minutes or more, and so on disinfection. Sterilizing techniques are used to keep the asepsis room highly sterile. Ultraviolet lamp should also be installed inside the inoculation box. The lamp should be turned on for more than 15 minutes before use to irradiate and sterilize, but there are still bacteria in the place where the light can not reach. When the ultraviolet lamp is turned on for a long time, the oxygen molecule in the air can be excited to form ozone molecule, which has a strong bactericidal effect on the ultraviolet ray does not directly irradiate the clumps. Ozone is harmful to health, before entering the operation should first turn off the ultraviolet light, after 10 minutes can enter.
Ultraviolet lamp can also be hoisted on the cleaning table, but should be installed outside the lampshade, and staggered lamp parallel arrangement, so that the operation does not interfere with lighting. It is useless to put ultraviolet light into the glass panel of the lampshade, because ultraviolet light can not penetrate the glass, its tube is made of quartz glass, not silicate glass.
The Vaccination Room strives to be concise, and all items not directly related to the operation of this room can not be put in, in order to maintain a sterile condition. The air in the inoculation room should be definitely obstructing the outside air, and the reserved ventilation holes should be kept as close as possible. The upper and lower air windows can be provided in the ventilation passage, and the area of the air window should be slightly larger. 4 gauze cloth should be covered for simple filtration. After a day's homework, the window can be fully ventilating and airtight. In the end, it must be clean and clean, sterile and fresh air, and suitable for homework. Gauze on the ventilation window should be changed frequently. However, the above-mentioned methods only aspire to the design scheme, often difficult to fully achieve, in fact, only strict aseptic procedures, in the doors and windows open indoor, cleaning table maintenance, vaccination contamination rate can still be controlled in production to tolerate the level.
