Description
Technical Field
The invention relates to the technical field of biological safety protection and equipment, in particular to the field of key protective barrier equipment for carrying out experiment operation of highly pathogenic microorganisms and feeding infected poultry animals in a high-grade biological safety laboratory, and particularly relates to pecking-proof sheets for a biological safety type poultry negative pressure isolator.
Background
A biological safety type negative pressure isolator for fowls is a key protective barrier device for carrying out experiment operation of highly pathogenic microorganisms and feeding infected fowls, and ensures the safety of experimenters and the environment by the technical means of airtight isolation of a box body and a transfer device, air negative pressure isolation, oversleeve operation, safe and reliable efficient air filtration and disinfection and the like. According to the requirement of 5.2.2 e on negative pressure animal cages (negative pressure isolators) in the application instruction of CNAS-CL53 for the evaluation of key protective equipment by laboratory biological safety approval criteria, the leakage rate of the internal pressure of the isolators is not more than 0.25 percent of the net volume per hour when the internal pressure of the isolators is lower than 250 Pa of the surrounding environment.
In the prior art, when the poultry negative pressure isolator is used for raising poultry animals, when an operation long glove on the isolator extends into an isolation cabin, the sleeve part of the operation long glove is exposed in the isolation cabin and is easy to be damaged by poultry, so that the isolator leaks, and the air tightness requirement of a working area cannot be met.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide anti-pecking sheets for a biological safety type poultry negative pressure isolator, which have simple structure and reasonable design and can prevent the poultry from pecking the operating gloves on the isolator.
In order to achieve the purpose, the invention adopts the following technical scheme:
a prevent pecking the piece for biohazard safety type birds negative pressure isolator, be equipped with the cofferdam on the isolator, be equipped with the sleeve lantern ring on the glass window of cofferdam, install operating gloves on the sleeve lantern ring, prevent pecking the piece including preventing pecking the piece body, prevent pecking the entry that the operating gloves that the piece body was equipped with on the surface and supplied to install on the sleeve lantern ring stretched into, the entry is by preventing pecking a plurality of incision that the piece body center is radial distribution to extending all around and constitute, prevent pecking the piece body and fix on the sleeve lantern ring through its peripheral flange.
Be equipped with the fixed orifices on the flange, correspond the fixed orifices on the sleeve ring and be equipped with the mounting hole, prevent pecking the piece body and fix on the sleeve ring through the bolt that passes fixed orifices and mounting hole in proper order.
The pecking-proof piece body is made of elastic materials.
Preferably, the pecking prevention piece body is formed by a silica gel material with good flexibility.
And , the number of the notches is 6.
By adopting the technical scheme, the pecking-preventing piece body is fixed on the sleeve ring on the glass window of the isolation cabin, when an operating glove arranged on the sleeve ring extends into the poultry isolation cabin, the cut of the pecking-preventing piece is opened towards the isolation cabin, and the pecking-preventing piece opened towards the isolation cabin can shield the sleeve part of the operating glove, so that the operating glove can be prevented from being damaged by poultry.
The invention can effectively prevent birds from pecking the oversleeves of the operation gloves, ensure that the biosafety type poultry negative pressure isolator does not leak, ensure that the biosafety type poultry negative pressure isolator meets the requirement of air tightness, simultaneously reduce the possibility of mutual cross contamination between an operator and the interior of the isolator, reduce the working risk of the operator and protect the occupational health and safety of the operator.
Drawings
The invention is further illustrated in step with reference to the following figures and detailed description:
fig. 1 is a schematic view of the peck prevention sheet of the present invention.
Detailed Description
As shown in fig. 1, the anti-pecking plate for the bio-safety type negative pressure isolator for birds of the invention is characterized in that an isolation cabin is arranged on the isolator, a sleeve ring is arranged on a glass window of the isolation cabin, gloves are arranged on the sleeve ring, the anti-pecking plate comprises an anti-pecking plate body 1, an inlet for the gloves arranged on the sleeve ring to extend into is arranged on the surface of the anti-pecking plate body 1, the inlet is composed of a plurality of notches 2 which extend from the center of the anti-pecking plate body 1 to the periphery and are distributed in a radial shape, and the anti-pecking plate body 1 is fixed on the sleeve ring through a flange 3 on the periphery thereof.
The flange 3 is provided with a fixing hole, the sleeve ring is provided with a mounting hole corresponding to the fixing hole, and the pecking-proof piece body 1 is fixed on the sleeve ring through bolts 4 which sequentially penetrate through the fixing hole and the mounting hole.
The peck prevention piece body 1 is made of an elastic material or a material with strong flexibility, such as a silicone material.
In the present embodiment, the number of the slits is 6.
The pecking-proof sheet body is fixed on the sleeve ring of the glass window of the isolation cabin, when an operating glove arranged on the sleeve ring extends into the poultry isolation cabin, the pecking-proof sheet cut is opened towards the isolation cabin, and when the operating glove is pulled out of the sleeve ring, the pecking-proof sheet cut is automatically closed. The anti-pecking piece which is opened in the isolation cabin can shield the oversleeve part of the glove and prevent the oversleeve part from being exposed in the isolation cabin, so that the oversleeve part of the glove can be effectively prevented from being damaged by birds, the biological safety type bird negative pressure isolator is ensured not to be leaked, and the requirement of air tightness is met.
