Description

A gas output pipe of a humidifier

technical field

The utility model relates to a humidifier, in particular to a gas output tube of a medical humidifier in which a detachable heating device is coated on the outer peripheral edge of a tube body.

Background technique

In the intensive care unit or respiratory intensive care unit of the hospital, humidifiers have been widely used to meet the air supply needs of acute surgical patients or chronic respiratory patients.

The general humidifier structure mainly includes a container (chamber), which is provided with an air inlet, an air outlet and a water inlet, when the air and sterile water enter the container through the air inlet and the water inlet respectively , through heating by a warmer to generate warm and humid gas, and then make the warm and humid gas delivered to the patient in need through the gas outlet through a gas output tube.

The optimal temperature for the supply of the above-mentioned warm and humid gas is about 34°C to 37°C, and the temperature of the intensive care unit is set at about 21°C to 22°C. , it is easy to reduce the temperature and condense water vapor on the outer periphery of the gas output pipe. It is necessary to increase the temperature of the warm and humid gas in the container to compensate for the temperature dropped during the transportation process. However, this method of increasing the output temperature Still can't solve the problem of water vapor condensation, and after raising the heating temperature, it will relatively consume a large amount of sterile water and increase the cost of use.

In order to solve the above problems, U.S. Patent No. 3,856,051 has disclosed a structure in which a heating line is provided in the gas output pipe to directly heat the air in the pipe. The disadvantage is that it will cause turbulent flow of the warm and humid gas, which cannot be smoothly Provided to patients, and exposing the heating wire to warm and humid air, there is a potential hazard.

Therefore, U.S. Patent No. 7,120,354 discloses another structure in which a heating wire is provided on the outer periphery of the gas outlet pipe. The heating wire is formed simultaneously with the gas outlet pipe so that the heating wire is completely covered on the gas outlet pipe. Among them, it not only solves the problem of water vapor condensation, but also effectively avoids the temperature drop during the transportation process, does not cause turbulence, and can also obtain better safety guarantees. However, the integral molding of the heating wire and the gas output tube requires high cost. When the gas output tube has a slight air leakage due to damage, due to the requirements of medical quality, the whole piece needs to be replaced, which is not in line with economic benefits.
