Biological safety negative pressure isolator for poultry

Abstract

The invention discloses a biological safety negative pressure isolator for poultry. The biological safety negative pressure isolator comprises an operation box body, wherein an equipment layer and a bracket are respectively arranged on the upper and lower sides of the operation box body; an air supply and filter device and a first-stage air exhaust and filter device are respectively mounted at the left and right ends of the bottom of the equipment layer; the top of the operation box body communicates with the first-stage air exhaust and filter device and the air supply and filter device; a second-stage air exhaust and filter device communicating with the first-stage air exhaust and filter device is mounted at the bottom of the bracket; the left end of the second-stage air exhaust and filter device communicates with a gas disinfectant discharging outlet and a fan; the operation box body is provided with a pair of operation gloves; an equipment door is mounted on the left side wall of the operation box body and a first air tight door is mounted on the right side wall of the operation box body; the first air tight door communicates with a detachable transmission device with a second air tight door; and a liquid trough transmission device is arranged at the left end of the bracket. The biological safety negative pressure isolator for the poultry can enable experiment personnel to carry out various isolation operations such as poultry infection experiment, breeding and pestilence inspection and quarantine, is easy and convenient to operate, is high in air tightness, and can transmit an experimental object conveniently and safely.

Description

technical field [0001] The invention relates to the technical field of biosafety protection and equipment, in particular to a biosafety poultry negative pressure isolator, which is used for various isolation operations such as poultry infection experiments, breeding, and epidemic inspection and quarantine. Background technique [0002] In recent years, highly pathogenic avian influenza epidemics have occurred frequently around the world, and some areas in my country have become the hardest hit areas, causing serious economic losses. At the same time, cases of human infection with avian influenza continue to emerge. Since 2003, about 400 people worldwide have died from H5N1 highly pathogenic avian influenza, which has posed a serious threat to human health and social stability. Therefore, countries around the world have begun to increase investment in scientific experimental research related to avian influenza. In order to reduce the risk of infection, the operation of highl...

Problems solved by technology

[0004] At present, poultry isolators developed abroad usually do not have the conditions for in-situ leak detection of high-efficiency exhaust air filters, and most of the items are delivered by ordinary transfer windows or bucket-type liquid level seal transfers. Breeding and test operations are carried out in different isolators, and the birds need to be frequently passed between the two isolators. The operation process is cumbersome. The surrounding environment causes pollution, which seriously endangers the personal safety of the experimental staff, and the isolator takes up a lot of space, is expensive, and does not conform to the operating habits of ordinary scientific researchers
