Emergency respirator for nursing in pneumology department

Abstract

The invention discloses an emergency respirator for nursing in pneumology department. The emergency respirator comprises an air bag, wherein one end of the air bag is connected with an air inlet pipe,a pressure safety valve is arranged on the top of the air inlet pipe, a pressure gauge is arranged at one side of the pressure safety valve, and the other end of the air inlet pipe is connected witha duckbill valve; an exhalation valve is arranged at the bottom of the duckbill valve, the bottom of the exhalation valve is connected with a breathing mask, an air inlet valve is arranged at the other end of the air bag, and one end of an air storage valve is connected with an air storage bag. A driving pressure valve in the air inlet pipe can be monitored by arranging the pressure gauge, so thata doctor can intuitively master the air input according to the state of an illness of a patient, and a condition that the state of the illness of the patient is seriously harmed due to over-high pressure of an air passage caused by completely extruding the air bag by hand feeling when the patient inhales the air can be avoided; and meanwhile, fixed belts are arranged at two sides of a breathing mask, the fixed belts can fix the breathing mask at the head of the patient, the trouble that the doctor needs to fix the breathing mask by hand while pressing the air bag can be omitted, and the emergency respirator is time-saving and labor-saving.

Description

technical field [0001] The invention relates to a medical device, in particular to an emergency respirator for respiratory care. Background technique [0002] Simple respirator, also known as artificial respirator or pressurized oxygen bag, is a simple emergency tool for artificial ventilation. Compared with mouth-to-mouth breathing, it has a high supply concentration and is easy to operate, especially when the condition is critical and it is too late for tracheal intubation. Use the pressurized mask to give oxygen directly, so that the patient can get sufficient oxygen supply and improve the hypoxic state of the tissue. mask for artificial ventilation. [0003] At present, the existing emergency respirators generally rely on manually pressing the air bag to supply oxygen, and the oxygen content cannot be controlled. If the airway pressure is too high when the patient inhales, the alveolar pressure of the patient will increase. When the alveolar pressure exceeds the pulmona...

Problems solved by technology

[0003] At present, the existing emergency respirators generally rely on manually pressing the air bag to supply oxygen, and the oxygen content cannot be controlled. If the airway pressure is too high when the patient inhales, the alveolar pressure of the patient will increase. When the alveolar pressure exceeds the pulmonary artery embedding pressure , which will block the blood flow in the lungs and reduce the cardiac output, thus seriously endangering the patient's condition
