Description
Technical field
The present invention relates to operating room supply air system field, relate in particular to a kind of clean operating room variable air rate and become other air-supply arrangement of level.
Background technology
Clean operating room is according to China's national standard " Standard for daylighting design of industrial enterprises " GB50333 requirement, clean operating room should require to arrange at indoor center the air-supply arrangement of corresponding different air supply areas according to different stage, to guarantee cleaning and the aseptic requirement of operative site.And " Standard for daylighting design of industrial enterprises " GB50333 has stipulated the operation that the clean operating room of different stage is suitable for it, and in other words, dissimilar operations should be carried out in the different stage operating room.
Clean operating room rank and suitable operation
| Grade | The operating room title | The operative incision classification | Be suitable for the operation prompting |
| Ⅰ | Special clean operating room | Ⅰ | Need highly aseptic operation in the operations such as joint replacement, organ transplant, cranial surgery, department of cardiac surgery and ophthalmology |
| Ⅱ | The standard clean operating room | Ⅰ | Thoracic surgery, plastic surgery, Urology Surgery, liver and gall pancreas surgery, Orthopeadic Surgery and get ovum transfer operation and general surgery in a class aseptic operation |
| Ⅲ | General clean operating room | Ⅱ | General surgery's (removing class operation), woman produce operations such as surgery |
| Ⅳ | Accurate clean operating room | Ⅲ | Operations such as anorectal surgical and pollution class |
Because clean operating room, especially the area of the special clean operating room of I level is big, facility good, cost is very high, and operating cost is big, and excessive risk amount for surgical such as joint replacement, organ transplant are few, cause the special clean operating room utilization rate of I level not high, free time is more.And the general clean operating room of III level is implemented common surgical procedures, and every day, amount for surgical was full, and operating room uses inadequately, and the general outer operation of sufferer such as need can only be lined up, sometimes because of long delay treatment of waiting time.Kindred circumstances, door emergency unit in hospital has to arrange II grade standard clean operating room because of needs of medical treatment, but utilization rate is not high, perform the operation and pollute class in a large number, cause that as traffic, fire and industrial and mineral accident invasive surgery, emergent operation need be at the accurate clean operating rooms of IV level, as long as be difficult to sometimes deal with than the accurate clean operating room quantity of the existing IV level of major break down together.As with general surgery, even contaminated operation carries out in high-level operating room, and then operating cost is very high, and sufferer is difficult to bear.For energy-conservation or reduction operating cost, the air output of senior operating room need be lowered, but what the operating room air-supply arrangement adopted is local displacement stream (or claiming laminar flow or way flow), not that turbulent air flow is sent in common air port, need keep cross section wind speed (can not be lower than 0.15m/s), otherwise can not keep the displacement gas properties of flow, also can't reach cleaning and the aseptic level of requirements of operation.As seen traditional thinking and measure can't realize variable air rate, other operation of conversion operating room level.
Summary of the invention
The purpose of this invention is to provide a kind of requirement according to dissimilar operations to change air output but to keep the cross section wind speed constant, under guarantee and the suitable germ-free condition of operative site, reduce the operating cost of operating room effectively, energy-saving and cost-reducing clean operating room variable air rate becomes other air-supply arrangement of level.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of clean operating room variable air rate becomes other air-supply arrangement of level, it comprises wind pushing box, the ajutage that connects described casing, the plenum chamber that connects described ajutage, the air-treatment mechanism that connects described plenum chamber, described wind pushing box comprises first wind pushing box that is set up in parallel again, second wind pushing box, the 3rd wind pushing box, described first, second, the 3rd wind pushing box bottom surface offers air-supply face, the corresponding described wind pushing box of described ajutage is provided with first ajutage, second ajutage, the 3rd ajutage, described first, second, the 3rd ajutage is provided with decides the air quantity device, described first, also be provided with closing device on the 3rd airduct.
Optimized technical scheme is provided with filter in described first wind pushing box, second wind pushing box, the 3rd wind pushing box.
Further technical scheme, described filter are arranged on described first wind pushing box, second bellows, outlet air surface top, the 3rd wind pushing box bottom.
Further technical scheme, described filter is arranged on the side that is connected with described ajutage in described first wind pushing box, second wind pushing box, the 3rd wind pushing box.
Optimized technical scheme is describedly decided the air quantity device for deciding the air quantity valve.
Optimized technical scheme, described closing device are the dibit Electric air valve.
Basic principle of the present invention is:
1, with the requirements of operation rank as the control parameter, can directly control opening and closing to change air output of dibit Electric air valve, realize changing between high-level (as I level or II level) operating room and low level (as III level or the IV level) operating room with this;
2, utilize air supply plenum chamber that air-treatment unit header pipe is divided into three road ajutages, employing is decided the air quantity device every transportation work style amount is fixed on required air quantity.When requirements of operation rank is turned down, pressed and be arranged on operating room inner control button.Close dibit Electric air valve on left side and the right side independence air-supply arrangement pipeline, control converter plant simultaneously and turn down air-treatment unit air output.Because left side and right side independence air-supply arrangement are not blown, have only center independence air-supply arrangement air-supply, operating room is by the high-level low level that converts to, and air-supply arrangement just dwindles air supply areas, and does not change air-supply cross section wind speed, thereby guarantees rank, cuts down the consumption of energy.When requirements of operation rank is heightened, pressed and be arranged on operating room inner control button.Open dibit Electric air valve on left side and the right side independence air-supply arrangement pipeline, control converter plant simultaneously and heighten air-treatment unit air output.Because left side and right side independence air-supply arrangement and center independence air-supply arrangement are blown simultaneously, operating room is converted to high-level by low level.Equally, air-supply arrangement only strengthens air supply areas, and does not change air-supply cross section wind speed.
Because technique scheme is used, the present invention compared with prior art has following advantage:
1, the present invention is provided with three independently wind pushing box, can change air supply areas and keep the cross section wind speed constant to change air output, to keep displacement stream characteristic;
2, the present invention can change the operating room rank according to the operation needs.
