Abstract
The utility model provides a gas single-flow-direction animal mouth-nose-type inhalation contamination mask which comprises a bell-shaped cover cup and a wedge section soft mask placed at a bell opening. A mouth-nose opening which can extend into and seal the mouth nose part of an animal is formed in the middle of the wedge section soft mask. A soft cover wrapping side is arranged on the outer circle of the wedge section soft mask and can tightly wrap a protruding cornice of the bell-shaped cover cup. A soft cover wrapping opening formed by extending of the soft cover wrapping side tightly wraps the outer wall of the bell-shaped cover cup. A hook cover fixing ring on the outer side of the soft cover wrapping opening is provided with three fixing hooks, a head top fixing belt which can be connected to an animal neck sleeve in a hanging mode, and fixing belts on two sides. A gas discharging single-way valve at the top of the bell-shaped cover cup is connected with a waste gas adsorption device. A gas inlet single-way valve on the middle-upper portion of the bell-shaped cover cup is connected with a contamination gas source device. A liquid discharging switch on the middle-lower portion of the bell-shaped cover cup is connected with a liquid collecting bottle. The gas single-flow-direction animal mouth-nose-type inhalation contamination mask has the advantages that a contamination mask can be fixed on the mouth nose part of the animal quickly and tightly, gas single-way flow can be well controlled, saliva secreted by the animal can be cleared at any time during a test, and the requirement for animal mouth-nose-type inhalation contamination is met.
Description
Technical field
This utility model provides a kind of gas single current to animal mouth and nose formula Inhalation face shield.
Background technology
Utilize in recent years medium-sized and larger animal for example: horse, pig, sheep, dog, cat particularly dog class animal carries out respiration test, be used for studying Sucked medicine and pollutants in air and pathogen for anthropogenic influence, research and the application of this type of simulation scientific experiments obtain develop rapidly, in current scientific experiments research and application, great majority only can be with hose connectionly adding a drain hose to the compressed air source unit of contaminating again and be connected to outdoor by one on simple respiratory surface enclosure animal mouth and nose, simple face shield is had no idea fine fixing, easily loose or dislocation pollutes, the simple pipeline that does not have one-way cock to control may cause two-way ventilation repeatedly, the waste gas such as carbon dioxide that animal is breathed out can be repeated to suck, the exhaust gas dilution that specific contamination gas can be breathed out, waste gas streams can cause contamination inhaled concentration inaccurate to may reversely turning back to contamination source of the gas, carbon dioxide accumulation concentration raises and causes laboratory animal anoxia, do not have the face shield of specific draining function can make the saliva of animal secretion in test pollute or stop up nostril etc. shortcoming to become when last large technical barrier, had a strong impact on and restricted the research of this type of scientific experiments, application and development, so develop a kind of medium-sized and larger animal mouth nose of can being tightly fixed on fast, do not have the anti-stream of the gas cross gas single current that the saliva of animal secretion pollutes in clearance test at any time again to become current urgent needs to animal mouth and nose formula Inhalation face shield.
Summary of the invention

on the breather check valve 25 of intake interface pipe 23 inside of bell cup 21 middle upper portion can only be along with animal used as test simultaneously, during expiration, breather check valve sheet 24 can be adjacent to a circular intake valve port 2 that protrudes from inside pipe wall the breather check valve 25 of intake interface pipe 23 inside is closed, discharge gas check valve sheet 3 and breather check valve sheet 24 and form along with animal used as test breathes respectively alternately open closed the individual event gas flow that does not affect animal breathNow first the exhaust connection of exhaust gas adsorption device 57 being sealably coupled to exhaust port pipe 6 short tube outsides is provided with circle sealing joint circle 8 places and is connected and fixed, again the inlet pipe connection 1 of contamination compressed air source unit 22 being connected to intake interface pipe 23 short tube outsides is provided with circle sealing joint circle 8 places and is connected and fixed, just can the contamination gas one way flow in contamination compressed air source unit 22 is interior for Animal Inhalation Toxicity Exposure gas to bell cup 21, and the waste gas one direction that animal used as test is breathed out passes out to exhaust gas adsorption device 5, waste gas is safety dumping after the waste gas sorbing material 4 of exhaust gas adsorption device 5 inside can carry out adsorption treatment, the waste gas such as carbon dioxide that in whole experimentation, animal is breathed out have one-way cock to control can not cause two-way ventilation repeatedly, waste gas streams is to also can not reversely turning back to contamination compressed air source unit 22, can not cause the animal used as test anoxic that contamination inhaled concentration is inaccurate or carbon dioxide accumulation concentration raises and causes, the exhaust gas dilution that specific contamination gas also can not be breathed out, breathing mask can be easy to install fixing can not just can not polluting by loose or dislocation, and the face shield that has specific draining function can not make the saliva of animal secretion in experiment pollute or stop up nostril, after having tested, first disconnect the inlet pipe connection 1 of contamination compressed air source unit 22, disconnect again the exhaust connection 7 of exhaust gas adsorption device 5, unclamp animal neck 16 covers on animal used as test neck, take off the fixedly fixed hook 13 of the hook cover retainer ring 14 of crown fixed band 17 and two both sides fixed bands 15, release gently the animal face shield that is arranged on animal used as test mouth and nose part, the receipts liquid bottle 10 being connected on pulling down the wedge cross section soft face mask 18 that is arranged on bell cup 21 and being arranged on the discharge opeing mouthpiece 11 of bell cup 21 middle lower portion with draining switch 12, by receiving the animal secreting liquid of collecting in the inner experiment of liquid bottle 10, clean up.
