Compared with the prior art, the utility model has the advantages that:
1. the lower side of the bracket is attached to the nose lip area to form an air supply part, an air inlet main pipe is arranged at the front side or the side of the air supply part, and an air inlet branch pipe is arranged at the side wall of the air inlet main pipe; in the non-operation period, the air inlet branch pipe is connected with an oxygen supply system of a hospital ward; in the operation period, the air inlet branch pipe is plugged, the breathing machine is directly connected to the air inlet main pipe, a nasal catheter is not required to be replaced, and the method is rapid and convenient.
2. The three-dimensional bracket comprises the air supply part formed by being attached to the nose lip area, the arc-shaped upper edge erected on the root of the nose bridge and the side wing edges attached to the two side areas of the nose, and the three-dimensional outline of the three-dimensional bracket is attached to the nose naturally, so that the three-dimensional bracket has a certain fixing effect and can improve the comfort of a patient.
3. The upper side of the air supply part is provided with two nasal tubes which are respectively communicated with the air inlet main pipe, the nasal tubes are correspondingly arranged at the nostrils and partially extend into the nostrils, the outer wall of each nasal tube is also sleeved with a sealing part, and the sealing parts can be used for sealing gaps between the nasal tubes and the nostrils and preventing oxygen from overflowing. Compared with a nose cover structure, the nose cover structure ensures the tightness and simultaneously exposes the outer outline of the nose of a patient, thereby greatly improving the wearing comfort.
