Abstract
The utility model discloses a portable negative pressure isolation chamber, which comprises a chamber body, a polyurethane air-tight gas-tight zipper, an inlet gas filtering device, an exhaust filtering device, and a vacuum pump. The chamber body is an air-tight chamber body which is made of nylon cloth coated with polyurethane on both surfaces thereof and is supported by a framework, the polyurethane air-tight gas-tight zipper is arranged on a tent at the site where a long slit is formed, and the inlet gas filtering device and the exhaust filtering device are arranged on the chamber body. Theportable negative pressure isolation chamber has the benefits of good foldability, light weight, no toxicity, environmental friendliness, good high temperature and low temperature resistance, high chemical resistance, high tensile strength and tearing strength, and low damage liability. The isolation chamber can avoid the spreading of pathogenic microorganisms, and provides an effective measure for rapid on-site control of epidemic spreading in various environmental conditions. The isolation chamber can also carry out the corresponding treatment measures of infected patients in an isolation condition through any means of transportation, and at the same time transfer the patients to the upper-level mechanism for isolation and treatment of infectious diseases.
Description
Technical field
This utility model relates to a kind of cofferdam, is specifically related to a kind of portable negative-pressure cofferdam that forms inner 10-38Pa negative pressure value.
Background technology
At present, known negative pressure ward does not possess flexible performance.
This utility model provides a kind of portable negative-pressure cofferdam, breaks out the place in sudden infectious disease, infected personnel is isolated from rapidly carries out medical treatment and transhipment in the negative pressure cabin, avoids epidemic transmission.
Summary of the invention
Task of the present utility model is to be achieved through the following technical solutions: this portable negative-pressure cofferdam cofferdam comprises cabin body (1), the airtight watertight zip fastener of polyurethane (2), air intake filter (10), exhaust and filtration apparatus (5), vacuum pump (7); Described cabin body (1) is the closed cabin body made from the material of the two-sided coated polyurethane film of nylon fabricbase (1) that has skeleton to support, an airtight watertight zip fastener of polyurethane (2) is installed at the position that has slit at tent, on the body of cabin, be provided with an air intake filter (10), on cabin body (1), be provided with an exhaust and filtration apparatus (5) in addition, the filter element of described air intake filter (10) is that the nominal pore size is the nucleopore membranes (11) of 0.2um, and the filter element of described exhaust and filtration apparatus (5) is that the nominal pore size is the nucleopore membranes (6) of 0.2um.
After slide fastener (2) was opened, the people can enter cabin body (1), and again with the slide fastener driving fit, the hospitalized patients in the cabin body (1) just is in the airtight container.
Exhaust and filtration apparatus (5) is connected by closed conduit with vacuum pump (7), and energising starts vacuum pump (7), and the cabin body has just produced mobile air circulation in (1).
The nucleopore membranes filter area of air intake filter (10) is 10%-40% less than exhaust and filtration apparatus (5) nucleopore membranes filter area, circulates 10-38Pa negative pressure value state under the air condition thereby produced cabin body (1).
The beneficial effects of the utility model are: the airtight framing structure that the material of the two-sided coated polyurethane coating of cabin body and function nylon fabricbase is made, and foldable, in light weight, nontoxic, environmental protection, high-low temperature resistant, chemical resistance is strong, and tensile strength and tearing strength are high, and be not fragile.Because the cabin body is in negative pressure state, avoided the diffusion of pathogenic microorganism to propagate, for rapid deployment under a kind of various environmental conditions is controlled the effective measures that epidemic situation is propagated on the spot.This device also can will infect the patient by any means of transport to be implemented to be transported to higher level's infectious disease isolation treatment mechanism in the corresponding treatment measure under the isolation condition.
