うになって来（゛いる。<Prior art> Oxygen therapy has traditionally been performed for patients with respiratory diseases by providing oxygen from oxygen cylinders, and recently oxygen therapy using R-enriched air obtained by concentrating oxygen in the air has been used. As new treatments are developed, these treatments become increasingly popular.

蒸気に近い水蒸気が含有されることが多い。In these oxygen therapies, when a gas such as oxygen or Flu-enriched air is supplied to the patient's 0 cavity, the gas is usually humidified to near the saturated water vapor pressure in order to prevent the patient's OFf from drying out. Efforts have been made to provide the following. That is, in the case of oxygen from an oxygen cylinder, since the humidity is too low as it is, it is passed through a bubble type humidifier or the like to humidify the oxygen before being supplied to the patient. In addition, adsorption-type oxygen enrichers and de-type oxygen enrichers are used to obtain oxygen-enriched gas, but even in the case of adsorption-type oxygen enrichers, water is usually added to the oxygen-enriched gas. Enriched gas is supplied to the patient, which is humidified using a humidifier because it contains almost no gas. In the case of a de-type oxygen enricher, an oxygen-selective permeable membrane is used, and the air that permeates through the membrane is enriched with oxygen and water vapor, resulting in an oxygen-enriched air that is close to saturated water vapor. Often contains water vapor.

手段と、鼻カニユーラ等の使用者への供給手段とその間
を連結するためのＳ管手段からなる装置が用いられる。In order to provide such oxygen-enriched air or breathing gas such as oxygen, a breathing gas generating means such as a cylinder or an oxygen enricher is normally connected to a means for supplying it to the user such as a nasal cannula. A device consisting of an S-tube means is used for this purpose.

孔用カヌーラを継いで使用する方法が一般的であった。For example, you can extract enriched air from an oxygen enricher, use a long tube (also referred to as an extension tube) as a means of free movement around the sleeping area, and connect a nostril cannula to the end. The method used was common.

いことがあった。<Problem to be Solved by the Invention> In such a conventional breathing gas supply device, the temperature of the atmosphere used is the saturation temperature of the air in the extension tube, that is, the water vapor in the breathing gas reaches the saturated vapor pressure. Below the corresponding temperature, water condensation occurs in the extension tube,
The water droplets may scatter into the user's nostrils, causing discomfort or causing dirt inside the tube. To prevent this problem, the problem can almost be solved by increasing the ambient temperature, so-called heating, but it is uneconomical to heat the room 24 hours a day at night in ordinary homes, hospitals, etc. Furthermore, when considering use in mountainous areas during extremely cold winters, there are cases where heating cannot solve all problems.

生手段が得られた。When this device was operated with an extension tube length of approximately 3 TrL in a room at a temperature of approximately 12°C for approximately 2 hours at an oxygen enriched gas supply rate of 2ρ/1n, water droplets were generated within the tube. could hardly be seen. When the same operation was performed with the fiber IF layer coating removed from the outer surface of the extension tube, many water droplets were observed to form on the inner wall of the extension tube. Thus, by coating the outer surface of the extension tube with a fibrous layer, an obvious means of generating water droplets was provided.
