Example 1:
On the basis of a general clinical oxygen mask, as shown in fig. 1, 2 and 3, the oxygen mask of this embodiment is a hollow shell formed by a first shell 100 and a second shell 200, the second shell 200 is connected to a connecting surface 120 located at the center of the first shell 100, a plurality of through holes 210 are formed in the second shell 200, an oxygen port 110 is formed at the lower side of the first shell, and the oxygen port 110 is connected to an oxygen supply device through a cannula, so that oxygen is input from the first shell 100, overflows from the plurality of through holes 210 in the second shell 200, and when the oxygen mask is worn on the head, the overflowed oxygen can permeate into the oxygen mask for breathing of a patient.
As shown in fig. 3, there is a sealing member 400 penetrating through the connection surface 120 and fixed on the connection surface 120, and the sealing member 400 is "trumpet-shaped" and is formed by connecting a first opening 410 and a second opening 420, where the first opening 410 is opened and fixed on the connection surface 120. The first opening 410 and the second opening 420 are similarly elliptical in shape, and the second opening 420 is larger in size than the first opening 410, the second opening 420 encloses the mouth of the patient, and the second opening 420 encloses the mouth within the seal 400 after the oxygen mask is donned.
As shown in fig. 1 and 2, the support cannula 300 is inserted into the oral cavity through the sealing member 400, the support cannula 300 has a circular or oval shape, a diameter or minor axis size of 2cm, and a hollow structure inside for the entrance of endoscopic instruments. The outer side of the support cannula 300 is provided with a ring of holding rings 310, and the holding rings 310 are used for taking and placing the support cannula 300, and after the support cannula 300 is fixed in the oral cavity, the support cannula 300 is positioned on the surface of the connecting surface 120. The other side of the support cannula 300 is placed within the patient's mouth, propping the patient's mouth open. The length of the support cannula 300 is 2-5cm greater than the depth of the oxygen mask (the distance from the connection face 120 to the right side of the oxygen mask) and is sufficient to allow the support cannula 300 to open the mouth, thereby creating an endoscopic access passageway within the support cannula 300.
Preferably, the grip ring 310 is backed by a plug sized to be shaped and sized from the outer surface of the support cannula 300 to the inner surface of the seal 400 (inward from the first opening 410) and to securely hold the support cannula 300 within the seal 400, the plug having a holding depth of 0.5-3cm.

The adjusting member 500 is supported by a silica gel material, which has a good comfort in the oral cavity, the width of the adjusting member 400 is 0.5-1cm, the upper and lower surfaces are inwardly recessed to form curved surfaces, and generally the adjusting member 500 is used as an occlusion member, and teeth are placed on the upper and lower surfaces of the adjusting member 500. The anterior-posterior position of the adjustment member 500 can be adjusted to accommodate different patients, with teeth engaging the adjustment member during use with a better feel than engaging the outer surface of the support cannula 300.
The adjusting piece 500 can adjust the height of the adjusting piece 500 up and down except that the front and back positions are adjustable, different patients can be matched by selecting the adjusting piece 500 with different heights, compared with a method of personalized adjustment by a complex mechanical adjusting mechanism, the adjusting piece 500 is different, and the adjusting piece is more in line with clinical practice, and an oxygen cover is generally disposable in clinic, so that the adjusting piece 500 with different height and size can be configured to sufficiently meet clinical use, the comprehensive cost is lower, the medical care use is more convenient, and independent use training or complex clinical operation is not needed.
Example 4:
On the basis of the above embodiment, considering the requirement for auxiliary support fixation during the endoscope operation, as shown in fig. 7, the support member 320 is formed by protruding outwards from the lower direction of the outer side surface of the grip ring 310, the support member 320 is in the shape of an upwardly curved surface, the auxiliary protrusion 330 is provided on the curved surface, the support member 320 protruding outwards provides additional support for the endoscope after the endoscope is inserted, and the position of the auxiliary protrusion 330 is arranged next to the left and right sides of the endoscope, thereby further achieving the auxiliary fixation effect.
