Description
Technical field
The present invention relates to a kind of ward of changing the wind decontamination system that has, especially a kind ofly have a ward that negative pressure is changed the wind decontamination system, belong to Medical Devices manufacturing technology field.
Background technology
Communicable disease, especially pathogenic bacteria, virus can be propagated by flow air, viruses of once propagating on a large scale such as SARS particularly, its infectiousness, vitality are extremely strong, patients with infectious diseases for this character must carry out strict isolating and protecting, wards off disease and propagates to other people.
Present existing isolation way, normally the patient is taked quarantine measures, such as: adopt modes such as lesion isolations, ward isolation with between patient and the patient, isolate between patient and the non-patient, isolate contacting between modes such as medical personnel then take to dress protective clothes, wear gloves in treatment work, mouth cage and the patient.Though this mode has certain isolation effect, but when disease has stronger infectiousness, and germ, virus can be infected by number of ways, when causing disease patient of the same race to roll up, this traditional isolation method often can not play good effect.
In the existing isolation ward, patient expired waste gas is not handled timely, simultaneously, the new wind that enters isolation ward does not carry out disinfection yet, make the concentration of germ in the room air, virus higher, atmosphere draught-free in the ward causes the cross-infection and the propagation of germ, virus.Make germ, when virus has the long time-to-live after leaving human body, caused serious threat with the mobile germ of air, virus crowd to external world.
Therefore, the infection sources fully, isolate completely and sterilize, for preventing spreading of infectious disease, particularly prevent and have extremely strong infectiousness, spreading of the disease that can propagate by air is a kind of extremely effective method, also is one of problem anxious to be solved at present.
