Description
Technical field
The invention belongs to the medical building thing of special purpose, particularly a kind of infectious disease isolation ward of dynamic isolation formula.
Background technology
The respiratory infectious disease needs of patients is at the isolation ward internal therapy, isolation ward by between patients room, buffering, the washroom forms, it no matter is the isolation ward district that builds during the disease transmission, isolation ward is reconstructed in the part room that maybe will have hospital now, all adopt the negative pressure isolation technology, make inside, ward keep certain negative pressure value, leak into the outside not make the contaminated air in the ward with space outerpace.
The present negative pressure isolation technology that adopts, need make exhaust air rate greater than intake, realize the external negative pressure value in ward-more than the 15Pa (as the regulation of Australia's " classification and design criterion of hygiene medical treatment facility isolation ward "), form high negative pressure, to prevent that air from flowing backwards, therefore adopt two door frame hermatic door interlockings, the tens thousand of units of one door frame hermatic door (ward of during the SARS epidemic situation, building as Hong Kong), simultaneously, owing to lack foundation, consider for high safety, dare not utilize return air, emphasize to adopt whole fresh wind air-condition, this brings the complexity of ventilation and air conditioning system, expending of the energy influences its expanded application.
And the outstanding problem that the negative pressure isolation technology exists is, the whole isolated ward is in the high negative pressure state, only is just to show under the quiescent conditions that door is closed, and comes down to static the isolation.When under the current intelligence of switch door, people's turnover, the convection current of air internal-external temperature difference, not only pressure reduction disappears immediately, and high negative pressure is difficult to keep, and the inside and outside exchange of dusty gas is serious.Which kind of for this reason, need further to taking quarantine measures, how improving the isolation effect research experiment, so that propose more reasonably to solve the way of effectively isolating under the dynamic condition.
Summary of the invention
The objective of the invention is, on the basis of experimental study, design and produce a kind of dynamic isolation type infectious disease isolation ward, use the dynamic isolation technology, employing has 60-80 time/h ventilation rate, (studies have shown that, limits the quantity of less than 60 times, greater than 100 times, effect is little), 6-8m
3Between the buffering of volume, (studies have shown that, less than 6m
3Effect is bad); indoor negative pressure value reaches 3Pa; can keep crack between a door and its frame and suck wind speed greater than 0.5m/s; for the purpose of practicality; adopt 5Pa; its isolation effect is that 30-40 times (one sect, doorway, ward) is to 2500-3000 times (inlet adds a sect again between buffering); thereby guarantee under above-mentioned dynamic condition effective isolation with space outerpace; simultaneously; the medical personnel top of the head in the operation of sick bed limit is provided with air outlet; constitute the air-supply main flow area; because research conclusion learns that this district's pollution concentration is 2/3 of the average pollution concentration in room, because dynamic air current shrouds medical personnel; thereby protect it to avoid patient expired thing influence. the return air inlet in the ward is provided with no leakage type high efficiency particulate air filter; not only inspection-free leakage, and its effect is to make 3,000,000 bacteriums can only have 1 to see through strainer. realize that isolation ward need not hermatic door; need not the air-conditioning air supply system of high negative pressure and brand-new wind. reach easy to operate; medical personnel are safer, are suitable for the purpose of popularization.
Technical scheme of the present invention is, a kind of dynamic isolation type infectious disease isolation ward, by between patients room, buffering, the washroom forms the airtight integral body of enclosed structure, employing has 60-80 time/h ventilation rate, 6-8m
3Between the buffering of volume, between between patients room and buffering, be provided with common vertical hinged door, lead to the common vertical hinged door of outer setting between buffering, top board place above the medical personnel's operating position of the sick bed limit of patients room and tailstock top board place, the main air outlet and time air outlet of air intake main flow area are set, the side-lower setting is provided with the return air inlet of no leakage type high efficiency particulate air filter in the head of a bed, form on medical personnel's orientation and send down row's cleaning air-flow, ward 10-12 time/h circulated air, wherein new wind only accounts for 3-4 time/h, and the air port air velocity is learnt from research, only is not less than 0.13m/s, the competence exertion effect, top board between buffering is provided with air outlet, and the wallboard bottom between buffering is provided with return air inlet, and inner top is provided with air outlet in the washroom, in the airtight integral outer of enclosed structure air-conditioner and ventilator are set, connect each air outlet with pipeline, exhaust blower is set, connect each air outlet and return air inlet with pipeline, exhaust duct is provided with the air intake that arm is connected to intake stack, constitutes the air-supply exhaust system.
Advantage of the present invention is that application dynamic isolation technology adopts to have the above ventilation rate of 60 times/h, is not less than 6m
3Between the buffering of volume; need not expensive hermatic door and need not high negative pressure to isolate; employing is provided with the air intake main flow area above the medical personnel's operating position of the sick bed limit of patients room; form on medical personnel's orientation and send down row's cleaning air-flow; thereby protect it to avoid patient expired thing influence. adopt no leakage type high efficiency particulate air filter; guarantee that return air also cleans; therefore need not the air-conditioning air supply system of brand-new wind. only need 10-12 time/h circulated air; the new wind of 3-4 time/h; every private room can be saved 7000 yuan of the electricity charge in 1 year. and it is safer to reach medical personnel; save the energy, be suitable for the purpose of popularization. be applicable to various infectious disease isolation wards.
