[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] This invention provides an endotracheal tube and gastric tube fixation device, including a fixation strap 1 that can be attached to the chin area of ​​a human body; the fixation strap 1 is generally flexible, and both ends of the fixation strap 1 are designed to be extended so that the extended ends of the fixation strap 1 can be attached to the cheeks of a human body, and the inner side of the extended ends of the fixation strap 1 is provided with an adhesive layer that can be adhered to the skin; a support strap 11 is provided on the front side of the fixation strap 1, and the middle section of the support strap 11 is fixedly connected to the middle section of the fixation strap 1; a support member 2 is provided on the support strap 11; a fixation component 3 for fixing the endotracheal tube is provided on the support member 2; and straps for wearing on the head are connected to both ends of the support strap 11.

[0023] Preferably, a baffle 12 is provided on the front side of the support belt 11. The two ends of the baffle 12 are bent and fixedly connected to the support belt 11, and there is a certain gap between the middle part of the baffle 12 and the support belt 11. The support member 2 includes a support plate 21 and a stop block 22. The lower half of the support plate 21 passes through the gap between the baffle 12 and the support belt 11, and the support plate 21 can move in the gap between the baffle 12 and the support belt 11. The stop block 22 is located below the support plate 21. The top end of the stop block 22 is embedded in the bottom end of the support plate 21, and the stop block 22 can extend and retract downwards from the support plate 21. A protrusion 221 is fixedly provided on the side of the block 22 facing the baffle 12, and a plurality of grooves 121 for the protrusion 221 to be inserted are provided on the side of the baffle 12 facing the block 22; a silicone layer is provided on the outside of the protrusion 221 and inside the grooves 121. When in use, the fixing component 3 of this application can be installed on the endotracheal tube first, then the fixing strap 1 can be attached to the patient's chin, and the entire fixing strap 1 can be bent so that the two extended parts are attached to the patient's cheeks. Then the strap can be put on the back of the patient's head so that the entire fixator is worn around the patient's mouth. In clinical applications, the endotracheal tube fixation devices currently in use are fixed in structure and cannot be adjusted during use, which can easily lead to pressure injuries to the patient's mouth. Therefore, in this application, the support plate 21 can move back and forth between the baffle 12 and the support belt 11. During operation, the baffle 22 needs to be pulled down so that the protrusion 221 on the baffle 22 disengages from the groove 121 on the baffle 12 to release the lock. Then, the entire support 2 can be moved to move the fixation component 3 and the endotracheal tube. The endotracheal tube can be moved periodically according to the actual application to alleviate the pressure injuries to the patient's oral cavity caused by the endotracheal tube being kept in a fixed position in the patient's mouth for a long time. After the displacement adjustment of the fixing component 3 is completed, the stop block 22 can be pushed towards the support plate 21, so that the protrusion 221 on the stop block 22 is inserted into one of the grooves 121 at the corresponding position. Since there is a silicone layer on the outside of the protrusion 221 and inside the groove 121, the silicone between the two is squeezed to increase the friction when in contact, so that the protrusion 221 can maintain the insertion state in the groove 121 in the natural state, so as to realize the locking function after the displacement adjustment of the support plate 21 and the fixing component 3.

[0024] Preferably, the fixing component 3 includes a fixing block 31; the side end of the fixing block 31 is fixedly connected to the support plate 21, and the fixing block 31 has a through hole 32 extending through both ends of itself; the fixing block 31 has a plurality of sliding grooves 33 inside, which are arranged equidistantly around the through hole 32 inside the fixing block 31, and each sliding groove 33 extends from inside the fixing block 31 into the through hole 32 area; each sliding groove 33 of the fixing block 31 is provided with a clamping block 34, which can move into the through hole 32 within the corresponding sliding groove 33; each clamping block 34 has a support rod 35 at its top end, the bottom end of the support rod 35 is fixedly connected to the corresponding clamping block 34, and the top end of the support rod 35 extends from the top end of the fixing block 31; the top end of the fixing block 31 and the corresponding part of each support rod 35 are provided with a slot 36 for the support rod 35 to move.

[0025] Preferably, the top of the fixing block 31 is provided with an adjusting member 37, which can rotate at the top of the fixing block 31; the middle of the adjusting member 37 is provided with a through hole 32 identical to that on the fixing block 31; the bottom end of the adjusting member 37 is provided with a guide groove 38 corresponding to the support rod 35 on each clamping block 34, and the guide groove 38 at the bottom end of the adjusting member 37 is respectively fitted onto the corresponding support rod 35; the guide grooves 38 at the bottom end of the adjusting member 37 are all designed with an arc trajectory, and each guide groove 38 is inclined, that is, one end of the guide groove 38 is close to the through hole 32 of the adjusting member 37, and the other end is close to the edge of the adjusting member 37; the fixing block The top of the fixed block 31 has an opening 311 for the bottom of the adjusting member 37 to be placed, and the bottom of the adjusting member 37 can rotate within the opening 311 at the top of the fixed block 31; the top of the fixed block 31 has a ring-shaped retaining ring 312, the outer wall of the retaining ring 312 is fixedly connected to the inner wall of the opening 311 of the fixed block 31; the bottom of the adjusting member 37 has an annular groove 371 for the retaining ring 312 to be placed, and the height of the annular groove 371 is greater than the height of the retaining ring 312; the top of the fixed block 31 has a plurality of slots 39 around the through hole 32, and the bottom of the adjusting member 37 has a plug 391 that can be inserted into the slots 39; When clamping and fixing the endotracheal tube, the guide groove 38 at the bottom of the adjusting member 37 can be moved on the corresponding support rod 35 by rotating the adjusting member 37. Since the guide groove 38 is designed to be inclined, when the adjusting member 37 is rotated towards the end of the guide groove 38 near the through hole 32, the guide groove 38 at the bottom of the adjusting member 37 will exert a pushing and pulling force on the support rod 35. This causes the support rod 35 to gradually drive the corresponding clamping block 34 from the slide groove 33 to the through hole 32, so that multiple clamping blocks 34 can converge towards the center of the through hole 32 at the same time until they come into contact with the endotracheal tube. At this time, the endotracheal tube can be clamped and fixed in the through hole 32 of the fixing block 31 because it is squeezed and clamped by multiple clamping blocks 34 at the same time. This prevents the endotracheal tube from detaching from the patient's airway during the patient's coughing process. Meanwhile, to prevent the adjusting member 37 from rotating in its natural state, this application designs a slot 39 and a plug 391. After the rotation adjustment of the adjusting member 37 is completed, the adjusting member 37 can be pressed so that the plug 391 at the bottom can be inserted into the corresponding slot 39 on the fixing block 31. In this way, the slot 39 forms a movement limit on the plug 391, so that the adjusting member 37 can no longer rotate. In this way, it can be locked after the multiple clamping blocks 34 clamp and fix the endotracheal tube, so as to prevent the adjusting member 37 from rotating in its natural state and causing the clamping blocks 34 to stop clamping and fixing the endotracheal tube. Secondly, when it is necessary to rotate the adjusting member 37, the adjusting member 37 is pulled outward, so that the insert block 391 at the bottom of the adjusting member 37 can disengage from the corresponding slot 39 on the fixed block 31, thereby releasing the restriction on the rotation of the adjusting member 37; wherein, when the retaining ring 312 at the top of the fixed block 31 moves up and down with the fixed block 31, the height of the annular groove 371 is set to be greater than the height of the retaining ring 312, so that the retaining ring 312 can move and rotate within the annular groove 371, thereby allowing the retaining ring 312 to have sufficient room for movement within the annular groove 371.

[0026] Preferably, the front side of the baffle 12 is provided with a gastric tube holder 4 for clamping and fixing the gastric tube; the front end of the gastric tube holder 4 is provided with multiple limiting holes 41 that match the diameter of the gastric tube, and the inner wall of the limiting holes 41 is provided with a silicone layer; the bottom end of the gastric tube holder 4 is provided with a perforation design; the front side of the baffle 12 is provided with multiple threaded holes 122; a rod 123 with a matching diameter is provided at the threaded hole 122, the front half of the rod 123 is provided with a thread that matches the threaded hole 122, and the end of the rod 123 is provided with a hand-tightening part that can be operated by hand.

[0027] Preferably, the support plate 21 is provided with an oxygen tube holder 5 for clamping and fixing the oxygen tube. The bottom end of the oxygen tube holder 5 is fixedly connected to the support plate 21, and the top end of the oxygen tube holder 5 is provided with a slot 51 for placing the oxygen tube. The inner wall of the slot 51 is provided with a silicone layer. In clinical practice, patients with endotracheal intubation require feeding and oxygen supply. When the oxygen tube is inserted into the airway through the endotracheal tube, the patient's coughing can easily cause a pressure shock to the oxygen tube, which may lead to the oxygen tube coming out of the endotracheal tube. Therefore, this application designs an oxygen tube fixator 5 for fixing the oxygen tube. In use, the slot 51 at the top of the oxygen tube fixator 5 can be fitted onto the oxygen tube, and the silicone layer on the inner wall of the slot 51 increases the friction when in contact with the oxygen tube, so that the oxygen tube is firmly positioned on the oxygen tube fixator 5, thereby preventing the oxygen tube from coming out due to the patient's coughing.

[0028] Secondly, when fixing the gastric tube, the limiting hole 41 at the front end of the gastric tube fixator 4 can be fitted onto the gastric tube, and the silicone layer can be used to increase the contact resistance to achieve clamping and fixing of the gastric tube. At the same time, when it is necessary to move the endotracheal tube to the left or right, the hand-tightening part can be turned to remove the insertion rod 123, and the position of the gastric tube fixator 4 on the baffle 12 can be adjusted according to the usage requirements. After the displacement adjustment is completed, the insertion rod 123 can be inserted through the perforation part on the outside of the gastric tube fixator 4, and the threaded part of the first half of the insertion rod 123 can be screwed into the threaded hole 122 of the baffle 12 in a spiral state to complete the fixing of the gastric tube.

[0029] Preferably, a pad 6 for the patient's teeth to bite is fixedly provided on the rear side of the fixing block 31, and the pad 6 has a through hole 32 in the middle that is the same as and connected to the fixing block 31. The pad 6 can be placed between the patient's upper and lower teeth during use to allow the patient's teeth to bite, while the through hole 32 can be used for the placement of the endotracheal tube, thereby supporting the patient's teeth and preventing the teeth from contacting the endotracheal tube, thus preventing the patient from biting and damaging the endotracheal tube.

[0030] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
