On the other hand, the outer surfaces of the two smooth protrusions are uniform The multiple gas inlet and outlet holes opened can play a role of diversion, and the area between two adjacent gas inlet and outlet holes that cannot pass through the gas can play a buffer role, so that the oxygen entering the patient's left nostril and the oxygen entering the patient's right nostril The impact force of oxygen in the nostrils can be effectively dispersed, which improves the patient's oxygen inhalation comfort, and the corresponding multiple gas inlet and outlet holes can also play a certain role in preventing blockage compared to the traditional one with only one gas channel. When a gas inlet and outlet hole is blocked, gas can also pass in and out through the unblocked gas inlet and outlet hole, and then, the utility model can achieve the best use effect.

Correspondingly, the overall structure of the utility model is simple, easy to implement, easy to operate, strong in practicability, strong in specificity, low in manufacturing cost, and does not need to increase too much cost in the improvement of the structure and the improvement of the technology, making the utility model The utility model must have good marketing value, and the utility model will be very popular and can be effectively popularized.

The above is only a preferred embodiment of the utility model, and does not therefore limit the scope of patent protection of the utility model. Any transformation of the equivalent structure or equivalent process made by using the specification of the utility model and the contents of the accompanying drawings, or directly or indirectly Applications in other relevant technical fields are all included in the scope of patent protection of the utility model in the same way.
