Description

Respirator face cover pastes facial cushion sectional fixture

Technical Field

The utility model relates to an anchor clamps technical field especially relates to a respirator face guard facial cushion sectional fixture.

Background

The respirator is a device which can replace, control or change the normal physiological respiration of a person, increase the ventilation capacity of the lung, improve the respiratory function, reduce the consumption of the respiratory function and save the reserve capacity of the heart. When the infant is complicated with acute respiratory failure, the infant needs to consider tracheal intubation and a breathing machine due to ineffective active conservative treatment, weakened respiration, excessive and thick phlegm, difficult sputum excretion, airway obstruction or pulmonary atelectasis. The ventilator must have four basic functions, namely, inflation of the lungs, switching from inspiration to expiration, removal of alveolar air, and switching from expiration to inspiration, which are sequentially cycled. Therefore, it is necessary to have: the gas transmission device has the advantages that power for gas transmission can be provided, and work of human respiratory muscles is replaced; secondly, a certain respiratory rhythm, including respiratory frequency and respiratory ratio, can be generated to replace the function of the respiratory rhythm dominated by the respiratory central nerve of the human body; the device can provide a proper tidal Volume (VT) or minute ventilation volume (MV) to meet the demand of respiratory metabolism; the gas supplied is preferably warmed and humidified to replace the nasal cavity function of the human body, and the amount of oxygen in the air can be supplied to increase the concentration of inhaled oxygen and improve oxygenation. The working principle of the breathing machine is as follows: when the patient is ventilated automatically, the inspiration action generates thoracic cavity negative pressure, the lung expands passively to generate pulmonary alveoli and airway negative pressure, thus forming pressure difference between the airway opening and the pulmonary alveoli to finish inspiration; after inspiration, the thorax and lungs elastically retract, creating an opposing pressure differential to complete expiration. Therefore, in normal breathing, the body generates an 'active negative pressure difference' between the alveoli and the airway opening through breathing action to complete inspiration, and the thoracic cage and the lung after inspiration elastically retract to generate a passive positive pressure difference between the alveoli and the airway opening to exhale so as to meet the requirement of physiological ventilation. The breathing of the breathing machine is completed by generating positive pressure difference between the airway opening and the alveolus through external mechanical drive, and the exhalation is completed by generating passive positive pressure difference between the alveolus and the airway opening through thoracic cage and lung elastic retraction after the external mechanical drive pressure is removed, namely the respiratory cycle has passive positive pressure difference.

The breathing machine accessory mainly comprises a host, a screen, an air compressor, a humidifier, an atomizer, a patient breathing pipeline, a nose mask and the like, when generated air flow enters the nose mask from the air inlet short pipe, the breathing mask isolates external air, and harmful gas or toxic gas is prevented from entering a human body breathing system.
