Gas circuit assembly, liquid storing device and breathing machine

Abstract

The invention discloses a gas circuit assembly, a liquid storing device and a breathing machine. The gas circuit assembly comprises an isolation piece and a first guide piece, wherein the isolation piece is provided with a first through hole and a second through hole; the first guide piece is formed on the upper surface of the isolation piece to construct a gas inlet channel in which gas current is guided into the first through hole and a gas outlet channel in which the gas current is guided out of the second through hole above the isolation piece; a gas return channel in which the gas current flows from the first through hole to the second through hole is formed below the isolation piece; the gas circuit assembly is arranged in the cavity of the liquid storing device when in use, and is enclosed into the gas inlet channel, the gas outlet channel and the gas return channel together with a shell assembly; the cavity is partitioned into an upper cavity and a lower cavity by the isolation piece; the first through hole communicates with a gas inlet through the gas inlet channel; the second through hole communicates with a gas outlet through the gas outlet channel. By adopting the gas circuit assembly, the liquid storing device and the breathing machine, the problem that a patient inhales water due to overflowing at the gas outlet can be solved at a certain degree.

Description

technical field [0001] The invention relates to the field of respiratory treatment equipment, in particular to an air circuit assembly for a ventilator, a liquid storage device with the air circuit assembly, a humidifier with the liquid storage device and a ventilator with the humidifier. Background technique [0002] Currently, continuous positive airway pressure using a ventilator is the main means of treating diseases such as sleep apnea syndrome (such as severe snoring). The liquid storage device and heating element are important components of the ventilator. Their functions are to warm and humidify the air, increase the moisture content in the air, make the gas inhaled by the patient warm and moist, and reduce the irritation of the cold and dry gas to the respiratory mucosa. , improve patient comfort. The heating element conducts heat to the water in the liquid storage device to accelerate the evaporation of the water, so that the air with the appropriate temperature a...
