DETAILED DESCRIPTION

[0014] In order to make the technical purpose, technical solution and beneficial effects of the present invention more clear, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] The present invention provides a tracheal tube fixing device, as shown in the figure, comprising an arc-shaped bracket, a sliding sleeve 3, a bite pad 8, and a tracheal tube 9.

[0016] Arc-shaped bracket: It matches the shape of the lips on the face and is mainly composed of an arc-shaped bar 1 and plates 2 arranged at both ends of the arc-shaped bar 1. A slide groove is opened on the arc-shaped bar 1 along its length direction. This slide groove is used for the installation and sliding cooperation of subsequent components, and can play a guiding and limiting role to ensure that the relevant components move according to the predetermined trajectory.

[0017] Sliding sleeve 3: The sliding sleeve 3 cooperates with the arc strip 1 of the arc bracket through the slider 4 provided thereon. The slider 4 is matched and slidably installed in the sliding groove. For example, the sliding groove is set as a dovetail groove, and the shape of the slider 4 is matched with the cross-sectional shape of the sliding groove, so that it can be limitedly installed in the sliding groove and slide. The slider 4 is provided with a through threaded hole. After the bolt 10 is screwed into the threaded hole and abuts against the arc strip 1, the relative position of the slider 4 and the arc strip 1 can be fixed, and then the position of the sliding sleeve 3 can be fixed, so as to realize the sliding and fixing functions of the sliding sleeve 3 on the arc bracket, and facilitate the adjustment of the position according to actual needs.

[0018] Bite pad 8: adjustably connected with the sleeve 3, the sleeve 3 is sleeved on the outside of the bite pad 8 and slidably cooperates with the bite pad 8, the outside of the sleeve 3 is hinged with a pressure plate 11 through a pin shaft, and a torsion spring 12 is sleeved on the pin shaft, and the two ends of the torsion spring 12 are respectively against the sleeve 3 and the pressure plate 11, so that the pressure plate 11 is squeezed by the torsion spring 12, and the end of the pressure plate 11 away from the torsion spring 12 is protruding downward with teeth 13, and the sleeve 3 is provided with an opening located on the rotation path of the teeth 13, and the bite pad 8 is provided with limiting grooves 14 at intervals along its length direction on the side opposite to the teeth 13. When the pressure plate 11 is acted upon by the torsion spring 12, the teeth 13 can pass through the opening and be inserted into the limiting grooves 14, thereby constraining the relative position of the sleeve 3 and the bite pad 8, meeting the adjustment requirements for the position of the bite pad 8, and ensuring a stable connection to prevent displacement.

[0019] The endotracheal tube 9 is detachably connected to the sliding sleeve 3. A cable tie is fixedly connected to the sliding sleeve 3. The cable tie is a prior art. The endotracheal tube 9 is located on one side outside the sliding sleeve 3. The cable tie bypassing the endotracheal tube 9 is used to fix its position.

[0020] The restraining mechanism is used to restrain the arc-shaped bracket to the head. It includes an upper left connecting belt 5, a lower left connecting belt 6, an upper right connecting belt, a lower right connecting belt and an annular connecting belt 7. The upper left connecting belt 5 and the lower left connecting belt 6 are respectively connected to the upper side and the lower side of one end of the arc-shaped bracket, specifically to the upper and lower sides of a pressing plate 11; the upper right connecting belt and the lower right connecting belt are respectively connected to the upper side and the lower side of the other end of the arc-shaped bracket, that is, to the upper and lower sides of another pressing plate 11, and the other ends of these four connecting belts are respectively connected to the upper left side, the lower left side, the upper right side and the lower right side of the annular connecting belt 7, and the annular connecting belt 7 is used to wrap around the back of the head. Through this connection method, the entire restraining mechanism can firmly fix the arc-shaped bracket to the head from multiple directions to prevent the device from shifting during use.

[0021] The method of using this device is: The arc bracket is placed at the corresponding position of the lips on the face, so that the arc strip 1 of the arc bracket fits the facial contour, and the plates 2 at both ends are in the appropriate position. Then, the sliding sleeve 3 is slid to the desired position along the sliding groove of the arc strip 1 through the sliding block 4. After the position is determined, the bolt 10 is screwed into the threaded hole of the sliding block 4 to fix the relative position of the sliding sleeve 3 and the arc bracket. After that, the position of the bite pad 8 is adjusted according to the patient's oral occlusion requirements (press the pressure plate 11 hinged on the outside of the sliding sleeve 3 to overcome the elastic force of the torsion spring 12 so that the teeth 13 of the pressure plate 11 leave the limiting groove 14 of the bite pad 8. At this time, the bite pad 8 can be slid to the appropriate position, and the pressure plate 11 is released. Under the action of the torsion spring 12, the teeth 13 pass through the opening of the sliding sleeve 3 and are inserted into the limiting groove 14 of the bite pad 8 to fix the bite pad 8). Then, the endotracheal tube 9 is placed on the outer side of the sliding sleeve 3, and the cable tie fixed on the sliding sleeve 3 is used to wrap around the endotracheal tube 9 and tighten it to ensure that the endotracheal tube 9 is stable. Finally, wrap the annular connecting belt 7 behind the head, pick up the upper left connecting belt 5, the lower left connecting belt 6, the upper right connecting belt and the lower right connecting belt, respectively connect the upper left side, the lower left side, the upper right side and the lower right side of the annular connecting belt 7, adjust the tightness of each connecting belt, so that the arc-shaped bracket fits the head tightly, and complete the fixation.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
