Gas-tight and water-permeable device and mechanical ventilation system

Abstract

The invention discloses a gas-tight and water-permeable device and a mechanical ventilation system. The gas-tight and water-permeable device comprises a ventilation channel, and a gas-tight and water-permeable membrane is arranged on the ventilation channel and used for discharging liquid towards the outer wall of the ventilation channel from the inner wall of the ventilation channel and preventing liquid and solid particles from entering the inner wall of the ventilation channel. According to the gas-tight and water-permeable device, liquid water mixed in gas is discharged through the gas-tight and water-permeable membrane, and then the gas is delivered back into a respirator, in other words, dried gas is obtained after treatment with the gas-tight and water-permeable film and delivered into the respirator to be treated; it is unnecessary to arrange a gas-tight and water-permeable membrane on a whole gas delivery pipeline, and thus cost is lowered.

Description

technical field [0001] The invention relates to the field of air-proof and water-permeable technology, in particular to an air-proof and water-permeable device and a mechanical ventilation system. Background technique [0002] At present, the air in the hospital's respiratory system generally enters from the inlet of the intake pipeline, and the heater connected to the intake pipeline heats the air, and then transmits it to the patient through the intake pipeline for breathing, and returns to the ventilator. It is transported through the return air pipeline. Due to the long length of the return air pipeline, and the hot air is easy to liquefy when in contact with the pipeline during the transmission process, forming small water droplets, which adhere to the return air pipeline and flow back to the ventilator, which is easy to damage the ventilator and affect the breathing effect. [0003] In the prior art, in order to discharge the water droplets out of the return air pipel...
