Abstract
The invention provides a positive-negative pressure switching purifying sickroom system, comprising a room for medical treatment, a front room, an air feeding/exhausting system and an air mount regulation and control system. The air feeding/exhausting system consists of a blower fan, a air conditioner for refrigerating or heating the fresh air, a blower fan for taking the air in front room to room for medical treatment, a horizontal laminar flow air feeding device taking the air in room for medical treatment to front room and an air exhausting fan. The sick room is under negative pressure when the amount of air exhausted of the air exhausting fan adjusted by the air mount regulation and control system is more than the amount of air fed of the blower fan while it is under positive pressure when the amount of air exhausted of the air exhausting fan is less than the amount of air fed of the blower fan. The invention has realized positive-negative pressure switching in the sickroom conveniently, can be widely used in treatment, hemopoietic stem cell transplanting treatment, neogenesis medical treatment, prophylactic measures anti-epidemic measures (airport, skeleton hospital), first aid treatment, flow pattern first aid treatment and isolation ward.
Description
[technical field]
The invention relates to a kind of medical facilities, particularly relate to a kind of positive and negative crush-cutting that can between positive negative pressure, switch easily and change the ward system that purifies.
[background technology]
In recent years, along with air-conditioning technical and development of auto-control technology, the equipment and the technology that purify the ward are gradually ripe, have occurred various malleations or negative pressure ward, are applied in the various hospital.In recent years, various acute epidemic infectious diseases constantly appear in the whole world, and cause of disease complexity is propagated soon, breaks with tremendous force, and brings huge pressure to medical department, for treating these infectious diseases, and have adopted increasing negative pressure ward.But, but the patient recover normal after, these negative pressure wards are incompatible again, make these negative pressure wards usually can not get sufficient utilization, have the phenomenon of resources idle to take place, and caused the wasting of resources.
[summary of the invention]
For solving the defective that above-mentioned malleation or Negative Pressure Isolation Ward exist in actual use, the invention provides and a kind ofly can carry out easily that positive negative pressure state is switched, positive and negative crush-cutting applied widely changes the ward system that purifies.
For achieving the above object, the invention provides a kind of positive and negative crush-cutting and change purification ward system, comprise a therapeutic room, a cup, send/exhaust system and an air volume control device.Wherein, this give/exhaust system comprise one with fresh air outside introduce therapeutic room new wind blower fan, to new wind freeze or the air-conditioner that heats, with the air in the therapeutic room deliver to cup return air fan, the air of cup is sent to the horizontal laminar flow air-supply arrangement of therapeutic room again and the air in the therapeutic room is drained into air draft blower fan outside the system of ward.Exhaust air rate by adjusting the air draft blower fan then is in negative pressure state in the ward greater than the air output of new wind blower fan, and when the exhaust air rate of the air draft blower fan air output less than new wind blower fan, then is in barotropic state in the ward.
Owing to adopt technique scheme, the present invention has following beneficial effect: it can be adjusted the air quantity of new wind blower fan, return air fan and air draft blower fan easily, and easily the ward is carried out the switching of positive negative pressure state, by adjusting indoor positive negative pressure, make the ward can be used for aseptic treatment, HSCT treatment, neogenesis medical treatment, anti-epidemic measure (airport, basic hospital etc.), emergency treatment, flow-type emergency medical and infectious ward etc.Like this, can not only satisfy the user demand in negative pressure ward, for example, when urgent epidemic infectious diseases occurring; And can under barotropic state, use this ward.Be particularly suitable for applying in the less area of small and medium-sized cities hospital and clean ward.
