Description

Anti-pressure sore oxygen nasal catheter

The invention relates to an anti-pressure sore oxygen nasal catheter, in particular to an oxygen nasal catheter structure which can be used in combination with a low flow oxygen supply method.

In the home oxygen treatment method, generally use low flow oxygen method, low flow oxygen method, also known as Low Flow Oxygen Therapy, is to supply low flow of 100% pure oxygen, plus the patient can breathe when breathing In an appropriate amount of atmosphere, the supplied gas is smaller than the patient's breathing volume. The low-flow oxygen inhalation oxygen concentration is not easy to control, and the effect of using the blood oxygen concentration detector is better.

At present, there are many low-flow oxygen supply devices, including oxygen nasal cannula [Nasal Cannula], oxygen catheter [Nasal Catheter], simple oxygen mask [Simple Mask], and partial re-breathing oxygen mask [Partial Re-breathing Mas]. k. Do not repeat the Non-Re-breathing Mask, Oxygen TENT, and Oxygen Hood.

The most common home is the oxygen nasal cannula [Nasal Cannula], the oxygen nasal catheter provides about 24% to 44% oxygen concentration, the oxygen flow rate is 0.5~6L, the nasal cavity is used as the storage cavity, so the nasal cavity must be smooth using the oxygen nasal catheter. If you use large flow or long-term use, you need to add oxygen humidifier to increase the humidity of the inhaled gas.

The advantages of oxygen nasal cannula are light, convenient, cheap and easy to tolerate, but the disadvantage is that it is easy to slip off. The oxygen concentration is easily affected by the change of breathing pattern. It is more likely to be pressed for a long time because of tube compression. And rubbing, making the skin tissue lack of nutrition and damage, and Produces pressure sores.

Therefore, when using an oxygen nasal cannula, it is necessary to add 3M tape to the user's cheeks to reduce the pressure of the pipeline, but this will not only increase the time and difficulty of nursing, but also because the gauze material is rough and easy to slide, or will Causes friction and causes skin breakage, and there is a certain risk of pressure ulcers.

In view of this, how to provide a nasal catheter structure that can be comfortably applied, is easy to apply, does not increase the time and difficulty of nursing, and can effectively prevent pressure ulcers from occurring, has become a subject to be improved by the present invention.
