As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model provides a kind of fiberoptic bronchoscope assisted endotracheal intubation mask, and it comprises annular airbag 1 and mask body, and described annular airbag 1 is connected with mask body, and described mask The body includes a fixed part 2 fixed on the annular airbag 1 and an opening part 3 that can be opened and moved. The fixed part 2 is provided with an oxygen connection tube 4, and a socket 6 is provided at the joint between the fixed part 2 and the opening part 3. The socket 6 is provided with a soft sealing cover 5 , and the opening part 3 is in sealing fit with the fixing part 2 .

An opening part 3 is provided on the special mask for fiberoptic bronchoscope assisted tracheal intubation, a socket 6 is set between the opening part 3 and the fixed part 2, and a movable soft sealing cover 5 is set on the socket 6, so that when opened, the fiberoptic bronchoscope It can be inserted into the nasal cavity through the socket 6 to ensure that the patient can carry out the auxiliary fiberoptic bronchoscope intubation operation under the condition of oxygen supply by the special mask for assisted endotracheal intubation through the fiberoptic bronchoscope. The tube operation is convenient and fast, and can effectively ensure the oxygen supply of the patient during the operation.

The fixing part 2 includes a base fixed on the annular airbag and the upper half-mask body, and the opening part 3 is in contact with the inclined surface of the upper half-mask body. The design of the inclined surface is adopted, and the pressing force of the inclined surface is used to ensure the close cooperation between the opening part 3 and the fixed part 2, and to ensure the sealing between the opening part 3 and the fixed part 2 more effectively.

Embodiment 1 is shown in Figure 4, which is the first schematic diagram of the cooperation between the fixing part 2 and the opening part 3. The edge of the fixing part 2 and the opening part 3 is provided with a boss 21a, and the opening part 3 is in contact with each other. The corresponding position is provided with a concave locking groove 31a, and the concave locking groove 31a forms a sealing snap fit with the boss 21a. The fixed portion 2 and the opening portion 3 are in contact with a boss 21a in the circumferential direction, and the opening portion 3 is provided with a concave groove 31a in the circumferential direction, and the opening portion 2 is clamped on the fixed portion 3 by using concave-convex cooperation, and it is guaranteed that it does not will fall off, and the concave-shaped draw-in groove 31a and the boss 21a adopt soft material, and the distance in the groove of the concave-shaped draw-in groove 31a is less than the thickness of the boss 21a, utilize the elasticity of the soft material, press the boss 21a to clamp, make It is used as a seal to protect the airtightness of the special mask for fiberoptic bronchoscopic assisted endotracheal intubation when both are closed.

Embodiment 2 is shown in Figure 5, which shows the second schematic diagram of the cooperation between the fixing part 2 and the opening part 3.
