Ventilation and liquid volatilization device, breathing mask, breathing tube and breathing support equipment

Abstract

The invention relates to the field of medical instruments, and discloses a ventilation and liquid volatilization device, a breathing mask, a breathing tube and breathing support equipment. The ventilation and liquid volatilization device comprises a ventilation tube, a liquid-proof breathable film and a gas-liquid one-way valve, wherein an inner channel of the ventilation tube forms a gas flow channel; the liquid-proof breathable film and the gas-liquid one-way valve are arranged on the gas flow channel at intervals in the axial direction of the gas flow channel; the gas flow channel comprisesa flow channel section located between the liquid-proof breathable film and the gas-liquid one-way valve; and at least one part of the flow channel section is a liquid absorption volatilization part.The ventilation and liquid volatilization device can allow gas such as gas with humidity to pass through and can adsorb and volatilize liquid possibly carried by the gas to the external environment,so that when the ventilation and liquid volatilization device is used for conveying breathing gas, condensate water possibly carried by the gas in the breathing tube can be collected and adsorbed andvolatilized to the outside. Therefore, the problem of discomfort caused by the fact that the condensate water is gathered and blown to the face, the mouth and the nose is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ventilating and volatilizing device, a breathing mask, a breathing tube and a breathing support device. Background technique [0002] In recent years, with the increasing maturity of non-invasive respiratory support equipment technology, non-invasive respiratory support equipment has become an important means of treating early chronic respiratory failure and chronic obstructive pulmonary disease. With the increasing development of respiratory support equipment, there are devices that can provide gas with higher humidity. When the high-humidity gas passes through the breathing gas pipe, condensation will accumulate on the inner surface of the breathing gas pipe to form water droplets, and as the condensation water droplets accumulate, water accumulation will be formed, and the accumulated water will be carried by the breathing gas and blown to the patient's face and body...

AI Technical Summary

Problems solved by technology

If it is installed at the position of the breathing mask, the breathing mask will be greatly hindered. In addition, the condensed water must be dumped during use or after use, and the operation is cumbersome
