At this time, the cam knob is maintained in a state of disengaging from the sliding tooth groove of the fixed support. Then the moving support can be moved left and right to move the tracheal cannula left and right. When the moving support moves the tracheal cannula to the appropriate position and needs to be fixed, the cam knob is again pulled to move counterclockwise downward. Since the movable hook is a metal part with high bending flexibility, toughness and strength, the rotation of the cam knob will force the movable hook to disengage from the buckle gap and reset to the sliding gap, thereby releasing the fixed constraint on the cam knob. Finally, the cylindrical section of the cam knob is returned to the sliding tooth groove of the fixed support, and the position of the tracheal cannula is fixed. BRIEF DESCRIPTION OF DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
[0045] The embodiments of the present application will be further described in detail below in combination with the drawings.
[0046] As Figures 1 to 11 , the embodiments of the present application provide a cam pressing type dental pad, which comprises:
[0047] The fixed support 1 is provided with a guide rail 11 in the left-right direction.
[0048] The moving support 2 is formed with a sliding groove 21, and is provided with a tracheal tube fixing groove 22 for inserting a tracheal tube. The guide rail 11 is embedded in the sliding groove 21, so that the fixed support 1 and the moving support 2 are connected and form a relative sliding relationship.
[0049] When the moving support 2 slides left and right relative to the fixed support 1, the tracheal tube moves left and right together with the moving support.
[0050] In order to make the tracheal tube after moving to the position fixed position, the tooth pad in the embodiment of the application is further provided with a cam buckle 3 and a movable hook 4 which can realize the position fixing of the moving bracket 2.
[0051] Referring to Figure 1 , Figure 2 , Figure 5 and Figure 7 , the moving bracket 2 is provided with a buckle position through hole 24, and the cam buckle 3 is provided with a fixed buckle position 33, which is clamped into the buckle position through hole 25 to realize the relative fixing of the moving bracket 2 and the cam buckle 3. Figure 9 and Figure 10 , the fixed bracket is provided with a sliding tooth groove 12 along the length direction thereof, and the cam buckle 3 comprises a cylindrical section 34; after the cylindrical section 34 is clamped into one of the sliding tooth grooves 12, the position of the moving bracket 2 relative to the fixed bracket 1 is fixed.
[0052] Meanwhile, as Figure 5 and as Figure 10 , the cam buckle 3 is clamped into the buckle position through hole 25 of the moving bracket 2 through the fixed buckle position 33 to realize the fixing on the moving bracket 2. Figure 9 and Figure 10 , the cylindrical section 34 of the cam buckle 3 is clamped into the sliding tooth groove 12 of the fixed bracket 1.
[0053] Since the fixed buckle position 33 of the cam buckle 3 has been clamped into the buckle position through hole 24 to realize the connection with the moving bracket 2, and the cylindrical section 34 of the cam buckle 3 is clamped into the sliding tooth groove 12 of the fixed bracket 1 to realize the connection with the fixed bracket 1. Therefore, the position of the moving bracket 2 is fixed, and the position of the tracheal tube is fixed.
[0054] In combination with Figure 1 , Figure 8 and Figure 11 , the movable hook 4 is connected and installed with the moving bracket 2 through the buckle position gap 25 on the moving bracket 2. At this time, the front end of the movable hook 4 is located on the sliding gap 32 of the cam buckle 3. The buckle position gap 25 is formed by opening a gap on the cylindrical section protruding on the moving bracket 2, and the movable hook 4 is clamped into the buckle position gap 25.
[0055] In combination with Figure 1 and Figure 2When the position of the tracheal cannula needs to be adjusted, the cylindrical section 34 of the cam knob 3 is pulled upward to move out of the sliding tooth groove 12 of the fixed bracket 1. Since the fixed buckle position 33 of the cam 3 is already fixed in the buckle position through hole 24 of the moving bracket 2, the cam knob 3 can only move clockwise along a circular track. At this time, since the movable hook 4 fixed on the moving bracket 2 is a metal part with high bending flexibility, toughness and strength, when the cam knob 3 moves clockwise along the circular track, the movable hook 4 will slide into the buckle gap 31 through the sliding gap 32 of the cam knob 3 to hook the cam knob 3, and at this time the cam knob 3 is maintained in a state of moving out of the sliding tooth groove 12 of the fixed bracket 1. Thereafter, the moving bracket 3 can be moved left and right to move the tracheal cannula left and right.
[0056] When the moving bracket 2 moves the tracheal cannula to the appropriate position and needs to be fixed, the cam knob 3 is pulled downward to move counterclockwise. Since the movable hook 4 is a metal part with high bending flexibility, toughness and strength, the rotation of the cam knob 3 will force the movable hook 4 to move out of the buckle gap 31 and reset to the sliding gap 32, thereby releasing the fixed constraint on the cam knob 3. Finally, the cylindrical section 34 of the cam knob 3 returns to the sliding tooth groove 12 of the fixed bracket 1, and the position of the tracheal cannula is fixed.
[0057] The above-mentioned cam pressing type pressure pad can solve the problem that the existing technology cannot adjust the position of the tracheal cannula after fixing it. At the same time, since it can be moved according to the needs, when cleaning the sputum in the patient's oral cavity, the sputum can be cleaned, maintained and the cleanable range can be expanded from multiple positions. When adjusting the position of the tracheal cannula, the cam knob 3 only needs to be pulled to adjust the position.
[0058] In order to realize the fastening and fixing of the tracheal cannula, refer to Figure 1 - to Figure 6 The dental pad in the embodiment of the application further comprises a tracheal cannula fixing sleeve 23, the tracheal cannula fixing sleeve 23 comprises three pressing tongue blocks 233 connected at the tail and capable of being pressed and tightened by a person, the inside of the three pressing tongue blocks 233 forms a channel for the tracheal cannula to pass through, a sliding guide rail 231 is arranged on the outer wall of the pressing tongue block 233, and a tooth 232 is arranged on the inner wall of the pressing tongue block 233; a sliding guide rail groove 221 is further arranged in the inside of the tracheal cannula fixing groove 22.
[0059] When the trachea cannula is fixed, the trachea cannula is first pushed into the left opening of the trachea cannula fixing groove 22 of the mobile support trachea 1 from the trachea cannula fixing sleeve 23, at this time, the three pressing tongue blocks 233 of the trachea cannula fixing sleeve 23 have been wrapped outside the trachea cannula, then the three pressing tongue blocks 233 are pressed, the sliding guide rail 231 is matched with the sliding guide rail groove 221 in the trachea cannula fixing groove 22, the pressing tongue blocks 233 are pressed down and the opening is contracted. The teeth 232 of the trachea cannula fixing sleeve 23 bite the trachea cannula, and the trachea cannula is fixed. The overall structure of the dental pad provided in the embodiment of the application is different from the prior art, which is simple, reliable and low in cost. The trachea cannula fixing mode in the embodiment of the application solves the problem that the prior art is too cumbersome in fixing the trachea cannula, and only needs to push the trachea cannula into the trachea cannula fixing groove 22 of the mobile support 2, and then press the three pressing tongue blocks 233 of the trachea cannula fixing sleeve 23, so as to fix the trachea cannula.
