Epidemic prevention respirator with waste gas purification function

Abstract

The invention discloses an epidemic prevention respirator with a waste gas purification function. The epidemic prevention respirator comprises device sliding wheels and a gas guiding pipe, wherein thetop parts of the sliding wheels are provided with a respirator bracket; the right upper side of the respirator bracket is provided with an air inlet; the left side of the air inlet is connected witha waste gas purifier; in addition, the top of the waste gas purifier is connected with an air cylinder; the top of the air cylinder is connected with an adjustable pressure reducing valve; in addition, the top of the adjustable pressure reducing valve is connected with an air storage bag; and the left side in the air storage bag is provided with a monitoring and alarming system. Due to the arrangement of the waste gas purifier, while external gases are sucked in, the device carries out purification processing on gases which are sucked in, a coarse filtering net and a fine filtering net are installed in the waste gas purifier, an efficient catalytic activity carbon core and a HEPA (High Efficiency Particulate Air) filtering core can purify the gases which are sucked in step by step, the purified gases can meet the requirements of a patient, and injuries to patients since gases contain harmful substances can be avoided.

Description

technical field [0001] The invention relates to the technical field of epidemic prevention ventilators, in particular to an epidemic prevention ventilator with exhaust gas purification function. Background technique [0002] The ventilator is an effective means of artificially replacing the spontaneous ventilation function. It has been widely used in respiratory failure caused by various reasons, anesthesia breathing management during major surgery, respiratory support treatment and emergency resuscitation. The ventilator is a kind that can It is a vital medical equipment for preventing and treating respiratory failure, reducing complications, saving and prolonging patients' lives. [0003] Most of the existing ventilators inhale the gas into the air supply chamber, and slowly inject it into the nasal cavity of the patient as the driving device works, but in practice, the inhalation of the gas does not take into account the composition of the gas. Whether there are many inh...

Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-epidemic ventilator with exhaust gas purification function to solve the problem that the inhalation of gas mentioned in the background technology does not take into account the composition of the gas, whether there are many inhalable particles in the gas, and whether it contains exhaust gas. Composition, whether the oxygen concentration of the ventilator is suitable
