Description
Technical field
The present invention relates to operating room supply air system field, particularly relate to the air-supply arrangement that a kind of clean operating room variable air rate becomes rank.
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 the air-supply arrangement arranging corresponding different air supply areas at indoor center, to ensure cleaning and the sterility requirements of operative site according to different stage.And the operation that the clean operating room that " Standard for daylighting design of industrial enterprises " GB50333 defines different stage is suitable for it, in other words, dissimilar operation should be carried out in different stage operating room.
Clean operating room rank is performed the operation with applicable
| Grade | Operating room title | Operative incision classification | Be suitable for operation prompting |
| Ⅰ | Special clean operating room | Ⅰ | Highly aseptic operation is needed in the operation such as joint replacement, organ transplant, cranial surgery, department of cardiac surgery and ophthalmology |
| Ⅱ | Standard clean operating room | Ⅰ | Thoracic surgery, plastic surgery, Urology Surgery, liver and gall pancreas surgery, Orthopeadic Surgery and the class aseptic operation got in ovum transfer operation and general surgery |
| Ⅲ | General clean operating room | Ⅱ | General surgery's (removing a class operation), woman produce the operations such as surgery |
| Ⅳ | Accurate clean operating room | Ⅲ | The operations such as anorectal surgical and pollution class |
Due to clean operating room, especially the area of I grade of special clean operating room is large, facility good, cost is very high, and operating cost is large, and joint replacement, organ transplant contour risk operations amount are few, cause I grade of special clean operating room utilization rate not high, free time is more.And III grade of general clean operating room implements common surgical procedures, every day, amount for surgical had a full house, and operating room uses not, and sufferer can only be queued up as needed general surgical operation, sometimes the delay treatment because waiting time is long.Kindred circumstances, in the Emergency call portion of hospital because needs of medical treatment have to arrange II grade standard clean operating room, but utilization rate is not high, and pollute class operation in a large number, as traffic, fire and industrial and mineral accident cause invasive surgery, emergent operation to need at IV grade of accurate clean operating room, as long as IV grade accurate clean operating room quantity existing compared with major break down is difficult to deal with sometimes together.As by general surgery, even contaminated operation carries out in high-level operating room, then operating cost is very high, and sufferer is difficult to bear.In order to energy-conservation or reduction operating cost, the air output of senior operating room is needed to lower, but what operating room air-supply arrangement adopted is that stream (or claiming laminar flow or way flow) is replaced in local, not that turbulent air flow is sent in common air port, cross section wind speed (can not lower than 0.15m/s) need be maintained, otherwise displacement gas properties of flow can not be kept, also cannot reach the cleaning of requirements of operation and aseptic level.Visible traditional thought and measures cannot realize the operation of variable air rate, conversion operating room rank.
Summary of the invention
The object of this invention is to provide a kind of requirement according to dissimilar operation to change air output but to maintain cross section wind speed constant, under guarantee with the suitable germ-free condition of operative site, effectively reduce the operating cost of operating room, energy-saving and cost-reducing clean operating room variable air rate becomes the air-supply arrangement of rank.
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 the air-supply arrangement of rank, it comprises wind pushing box, connect the ajutage of described casing, connect the plenum chamber of described ajutage, connect the air-treatment mechanism of described plenum chamber, described wind pushing box comprises again the first wind pushing box be set up in parallel, second wind pushing box, 3rd wind pushing box, described first, second, 3rd wind pushing box bottom surface offers air-supply face, the corresponding described wind pushing box of described ajutage is provided with the first ajutage, second ajutage, 3rd ajutage, described first, second, 3rd ajutage is provided with and determines air quantity, described first, 3rd airduct is also provided with closing device.
Preferred technical scheme, is provided with filter in described first wind pushing box, the second wind pushing box, the 3rd wind pushing box.
Further technical scheme, described filter is arranged on outlet air surface top bottom described first wind pushing box, the second bellows, the 3rd wind pushing box.
Further technical scheme, described filter is arranged on the side be connected with described ajutage in described first wind pushing box, the second wind pushing box, the 3rd wind pushing box.
Preferred technical scheme, describedly determines air quantity for determine air quantity valve.
Preferred technical scheme, described closing device is dibit Electric air valve.
General principle of the present invention is:
1, using requirements of operation rank as controling parameters, directly can control opening of dibit Electric air valve and change air output with closing, realize changing between high-level (as I grade or II grade) operating room and low level (as III grade or IV grade) operating room with this;
2, utilize air supply plenum chamber that air-treatment unit header pipe is divided into three road ajutages, employing is determined air quantity and every transportation work style amount is fixed on required air quantity.When rank is turned down by requirements of operation, press and be arranged on control knob in operating room.Close dibit Electric air valve on left side and right side independent air-feeding device pipeline, control converter plant simultaneously and turn down air-treatment unit air output.Because left side and right side independent air-feeding device are not blown, only have center independent air-feeding device air-supply, operating room converts low level to by high-level, and air-supply arrangement just reduces air supply areas, and does not change air-supply cross section wind speed, thus ensures rank, reduces energy consumption.When rank is heightened by requirements of operation, press and be arranged on control knob in operating room.Open dibit Electric air valve on left side and right side independent air-feeding device pipeline, control converter plant raising air process unit air output simultaneously.Because left side and right side independent air-feeding device and center independent air-feeding device 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 advantages:
1, the present invention is provided with three independently wind pushing box, can change air supply areas and keep cross section wind speed constant to change air output, to maintain displacement stream characteristic;
2, the present invention according to operation needs, can change operating room rank.
