Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0039] This application provides a spring-loaded mouthpiece, in which the movable support 2 is fixed and moved by the spring 4 between the movable support 2 and the fixed support 1; when fixing the endotracheal tube, the Velcro of the fixing strap 9 is used to fix the endotracheal tube, which is convenient and inexpensive to use.

[0040] Reference Figures 1 to 7 The spring-loaded mouthpiece includes: a fixed bracket 1, wherein the fixed bracket 1 is provided with a plurality of first locking positions 111 along the left and right directions;

[0041] A sliding block 3 is arranged inside the fixed support 1, and a second clamping site 31 is arranged on the sliding block 3 to form a clamping relationship with one of the first clamping sites 111.

[0042] A moving support 2 is fixedly connected to the sliding block 3 inside the fixed support 1.

[0043] A spring 4 is limited between a limiting portion of the moving support 2 and an outer wall surface of the fixed support 1.

[0044] A tooth pad 5 is integrally formed with the moving support 2, and the tooth pad 5 has a fixing groove 51 for fixing the tracheal cannula.

[0045] When the fixed position of the tracheal cannula needs to be adjusted, the nursing staff presses the moving support 2 inward, the spring 4 limited between the limiting portion of the moving support 2 and the outer wall surface of the fixed support 1 is compressed, at the same time, the moving support 2 drives the sliding block 3 to move inward, so that the clamping relationship between the second clamping site 31 of the sliding block 3 and the second clamping site 31 of the fixed support 1 is released; at this time, the nursing staff can move the position of the moving support 2 in the left-right direction, so as to realize the position movement of the tracheal cannula.

[0046] After the position movement of the tracheal cannula is completed, the moving support 2 is released, the spring 4 rebounds, drives the moving support 2 to move outward, so that the second clamping site 31 of the sliding block 3 and the other first clamping sites 111 of the fixed support 1 form the clamping relationship again, the moving support 2 is fixed, and the position of the tracheal cannula is fixed. At this time, the sliding block 3 and the inner wall of the fixed support 1 form a sliding block movement gap 13. Figure 5

[0047] When the nursing staff cleans the sputum in the oral cavity of the patient, the fixed position of the tracheal cannula can be adjusted, so as to realize the sputum cleaning, sanitary maintenance and expansion of the cleanable range from multiple positions.

[0048] Referring to Figure 1 , Figure 2 and Figure 6 ​The mouthpiece in the embodiment of the present application further comprises: a fixing belt 9, one end of the fixing belt 9 is fixed on the dental pad 5, and the other end is used for winding on the tracheal cannula to fix the tracheal cannula. The outer side of the fixing belt 9 is provided with a rough surface 92, and the inner side tail end is provided with a hook surface 93. In use, the tracheal cannula is placed into the fixing groove 51 left side opening of the dental pad 5, and then the inner side of the fixing belt 9 is wound on the surface of the tracheal cannula, and the hook surface 93 is connected with the rough surface 92 to realize the fixation of the tracheal cannula. The tracheal cannula fixing method solves the problem that the prior art is too cumbersome when fixing the tracheal cannula, and only needs to wind the fixing belt 9 on the tracheal cannula once to realize the fixation of the tracheal cannula, so that the tracheal cannula is quickly fixed, simple and reliable, and low in cost.

[0049] In the embodiment, the moving support 2 is a screw column, and the screw column section passes through the gap between the two guide rails 11 and is screwed into the threaded hole 32 of the sliding block 3.
