Abstract

FIELD: individual protection of respiratory organs from aerosols and dust. SUBSTANCE: respirator has replaceable filtering member and reusable adapter having specific shape. Filtering member is formed as hemisphere with trough-shaped obturator extending along its perimeter and two semicircular projections facilitating attachment of filtering member to adapter. Adapter is formed as ring defined by plastic tape and aluminum arched strip connected one with the other. Aluminum strip allows ring inner surface to adhere tightly to the whole surface of obturator strip. Plastic portion of ring is provided with four arched recesses for fastening two flexible cords and two T-shaped slots for fastening filtering member. Recesses and slots are positioned in diametrically opposed ring points and in symmetry with respect to aluminum portion serving as squeezing front plate. To use respirator, User inserts replaceable filtering member into adapter, conducts projections of filtering member into T-shaped slots of adapter, puts lower flexible cord on neck, brings filtering member close to face so that squeezing member is located on bridge of nose and chin is positioned in lower part of filtering member, puts upper flexible member on nape and presses nose plate so that it conforms with nose bridge shape. Length of fastening members may be adjusted to provide optimum adherence of filtering member to face. EFFECT: simplified constructions and enhanced reliability in operation.

Предлагаемый респиратор относится к средствам индивидуальной защиты органов дыхания от вредных для здоровья человека веществ в виде аэрозолей и пыли. Цель изобретения - создание простой технологичной для автоматизированного производства конструкции респиратора с высокими потребительскими качествами при одновременном повышении его герметичности по полосе обтюрации. Указанная цель достигается тем, что респиратор состоит из сменного фильтрующего элемента и алонжа многоразового использования, имеющего специальную форму. Фильтрующий элемент имеет форму полусферы, по периметру которой отформован желобообразный обтюратор и имеются два полукруглых выступа, которыми фильтрующий элемент крепится к алонжу. Алонж выполнен в виде кольца,образуемого из скрепленных друг с другом пластмассовой ленты и алюминиевой дугообразной полосы и изогнутого по форме, обеспечивающей прилегание внутренней поверхности кольца по всей полосе обтюрации. В пластмассовой части кольца имеются четыре дугообразные прорези для крепления двух эластичных шнуров и два Т-образных паза для крепления фильтрующего элемента, расположенных в диаметрально противоположных точках кольца и симметрично относительно алюминиевой полосы, выполняющей роль обжимной носовой пластины. При эксплуатации респиратора потребитель вставляет в алонж сменный фильтрующий элемент, заводит его выступы в Т-образные пазы алонжа, надевает нижний эластичный шнур на шею , прикладывает фильтрующий элемент к лицу так, чтобы обжимная пластина легла на переносицу, а подбородок находился в нижней части фильтрующего элемента, надевает верхний эластичный крепежный элемент на затылок и обжимает носовую обжимную пластину по форме переносицы. Регулируя длину крепежных элементов в дуговых прорезях алонжа, добиваются оптимального прилегания фильтрующего элемента к лицу.The proposed respirator relates to personal protective equipment of the respiratory system from substances harmful to human health in the form of aerosols and dust. The purpose of the invention is the creation of a simple technological design for automated production of a respirator with high consumer qualities while increasing its tightness over the obturation strip. This goal is achieved by the fact that the respirator consists of a replaceable filter element and a reusable sleeve, which has a special shape. The filter element has the shape of a hemisphere, along the perimeter of which a groove-shaped obturator is molded and there are two semicircular protrusions by which the filter element is attached to the allonge. Alonge is made in the form of a ring, formed from plastic tape fastened to each other and an aluminum arc-shaped strip and curved in shape to ensure that the inner surface of the ring fits over the entire obturation strip. In the plastic part of the ring there are four arcuate slots for attaching two elastic cords and two T-grooves for attaching a filter element located at diametrically opposite points of the ring and symmetrically with respect to the aluminum strip acting as a crimp nose plate. During operation of the respirator, the consumer inserts a replaceable filter element into the sleeve, winds its protrusions into the T-slots of the sleeve, puts the lower elastic cord on the neck, puts the filter element on the face so that the crimp plate lies on the nose, and the chin is in the lower part of the filter element , puts the upper elastic fastener on the back of the head and compresses the nose crimp plate in the shape of the bridge of the nose. By adjusting the length of the fasteners in the arc slots of the length, they achieve an optimal fit of the filter element to the face.
