Safe and reliable emergency rescue device

Abstract

The invention relates to a safe and reliable emergency rescue device, including a mixing cavity, a mixing tube, an air pipe, a connecting tube, a humidifying cavity, an exhalation tube, an inhalationtube, a breathing mask and a manipulator, wherein the mixing cavity is provided with a mixing mechanism; the mixing mechanism includes a translation assembly, a first motor, drive wheels and two air guide assemblies, the air guide assembly include a rotating shaft, Drive block, two blades and two bearings; the purification room is provided with a purification mechanism; the purification mechanismcomprises a filter screen, reciprocating assembly, a reciprocating plate and a plurality of vibration components; the vibration assembly includes a spring, diaphragm and two limit units. The safe andreliable emergency device regulates the oxygen concentration in the mixed gas through a mixing mechanism, Moreover, the total amount of the mixed gas is maintained in a stable range, which is conducive to the respiration of the patient, and the mixed gas is purified while the filter screen is dredged by the purification mechanism, so that harmful impurities are prevented from entering the body ofthe patient, thereby ensuring the respiration health of the patient.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a safe and reliable emergency rescue equipment. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It plays a very important role in the field of modern medicine. The ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] In the existing ventilator, the mixed gas of oxygen and air is mainly used as the gas source to supply gas to the patient, but in some special places (such as the scene of a fire), the dust and dust concentration in the air are relatively large, and when breathing , these...

Problems solved by technology

[0003] In the existing ventilator, the mixed gas of oxygen and air is mainly used as the gas source to supply gas to the patient, but in some special places (such as the scene of a fire), the dust and dust concentration in the air are relatively large, and when breathing , these impurities easily enter the patient's respiratory tract through the mixed gas, affecting the patient's respiratory health, thereby delaying the rescue work of the patient. Not only that, although the existing ventilator can adjust the mixing ratio of air and oxygen in the mixed gas, it cannot adjust The patient's inspiratory volume, when the patient's inspiratory volume is too small or too large, it will still affect the patient's recovery, resulting in reduced practicality of the existing ventilator
