Description

Mechanical ventilation breathing pipeline without condensed water

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a no comdenstion water mechanical ventilation breathing pipeline.

Background

When the breathing machine works, the temperature and humidity of air in the pipeline are higher than the indoor temperature and humidity, so that a large amount of condensed water is generated in the pipeline, and the high-risk factor is the high-risk factor causing pneumonia through a mechanical ventilation mode of the breathing pipeline. The existing heating type breathing loop heats and dries the condensed water by the heating wire in the tube, but has the following objective defects:

1. the heating wires in the pipes improve the temperature difference between the inside and the outside of the pipes, so that more condensation is accumulated;

2. condensed water is accumulated in the tube, so that the humidification effect of the ventilation gas is actually reduced, and the mechanical ventilation can not ensure that the relative humidity of the gas above 95 percent is easy to cause the damage of the respiratory airway;

3. a large amount of condensed water is an environment for bacteria propagation, and the phenomenon that the condensed water flows back to respiratory tracts or lungs occurs.
