[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a fixing mechanism for indwelling a gastric tube, including an ear-hanging rope 1, one end of the ear-hanging rope 1 is fixedly connected to a mounting frame 3, and the bottom inner wall of the mounting frame 3 is rotatably connected to a hinge column 4 through a bearing. By setting the hinge column 4, the hinge column 4 cooperates with the torsion spring 52 to make the hinge column 4 continuously stress the ear-hanging rope 1. When the patient's ear-hanging sleeve is set on the head, it prevents some patients from moving back and forth uncomfortably, causing the rope of the hanging sleeve to fall off from the head and the ear, thereby affecting the use of the gastric tube to a certain extent. The mounting frame 3 is provided with a mounting mechanism 5, and the ear-hanging rope 1 is provided with an auxiliary mechanism 6. The mounting mechanism 5 includes a pressing plate 50. By setting the pressing plate 50 to The hinge column 4 is pressed to move, and the pressing plate 50 is fixedly connected to the end of the hinge column 4 away from the mounting frame 3. The bottom end of the hinge column 4 is fixedly connected with a support plate 51. The support plate 51 is provided to prevent the hinge column 4 from detaching from the mounting frame 3. A torsion spring 52 is fixedly connected to the hinge column 4. An adjusting plate 53 is fixedly connected to the hinge column 4. The bottom outer wall of the adjusting plate 53 is fixedly connected with an arc plate 54. The arc surface of the arc plate 54 is squeezed by the annular plate 64 and moves backward. The bottom outer wall of the arc plate 54 is fixedly connected with a frosted pad 55. The frosted pad 55 is provided to fit the adjusting plate 53 to limit the hinge column 4 with friction resistance to prevent rotation. A small spring 57 is fixedly connected to the outer wall of one side of the arc plate 54.

[0025] Reference Figure 2-Figure 4 The arc plate 54 is slidably connected to the inner wall of one side of the mounting frame 3, and a paddle 56 is fixedly connected to the outer wall of one side of the arc plate 54. An outer wall of one side of the paddle 56 is provided with an indication mark, and the indication mark is set to prompt the operation method. A sponge pad is fixedly connected to the outer wall of the side of the pressing plate 50 away from the hinged column 4. By setting the sponge pad, the surface of the pressing plate 50 is softer, which improves the comfort of personnel pressing. One end of the torsion spring 52 away from the hinged column 4 is fixedly connected to the bottom of the mounting frame 3, and one end of the small spring 57 away from the arc plate 54 is fixedly connected to the inner wall of one side of the mounting frame 3. The other end of the ear hook rope 1 is fixedly connected to the hinged column 4. An air vent 2 is provided on the outer wall of one side of the ear hook rope 1. The air vent 2 is set to prevent the patient from wearing it for a long time. The ear hook rope 1 has a certain shielding on the skin, which makes the skin difficult to breathe, affecting the comfort of the patient wearing it.

[0026] Reference Figure 3-Figure 4The auxiliary mechanism 6 includes a nose bracket 61, which is slidably connected to the side outer wall of the ear hook rope 1, and the nose bracket 61 is arranged to fit the lower beam of the patient's nose. A gastric tube retention port 62 is provided on the side outer wall of the nose bracket 61, and a slider 63 is slidably connected to the side inner wall of the nose bracket 61. An annular disk 64 is hinged on the top outer wall of the slider 63, and a scale tooth 65 is provided on the side outer wall of the annular disk 64. The gastric tube placed in the gastric tube retention port 62 is clamped and fixed by setting a groove of the scale tooth 65 to prevent the gastric tube from moving back and forth during use, which may cause discomfort to the patient when entering deeper into the patient's body. A telescopic spring 66 is fixedly connected to the outer wall of one side of the slider 63, and an anti-skid pad is fixedly connected to the side outer wall of the annular disk 64. The anti-skid pad is arranged to facilitate personnel to rotate and adjust the annular disk 64 to push the gastric tube for fine-tuning and movement. The end of the telescopic spring 66 away from the slider 63 is fixedly connected to the inner wall of one side of the nose bracket 61.

[0027] Working principle: The ear hook rope 1 is put into the patient's head and then fits the patient's ear. Then the torsion force of the torsion spring 52 drives the hinged column 4 to rotate, and one end of the ear hook rope 1 is rolled up, and the patient's lock is adaptively adjusted to prevent the patient from moving and causing the fixed rope to loosen. Then, when adaptive adjustment is not needed and a fixed method is needed, the hinged column 4 moves by pressing the pressing plate 50, and the movement of the hinged column 4 drives the adjustment plate 53 to move, and the adjustment plate 53 moves to squeeze the torsion spring 52. At the same time, the adjustment plate 53 moves the edge arc plate 54, so that the arc plate 54 moves to squeeze the small spring 57. When the adjusting plate 53 moves to a certain position at the bottom, the arc plate 54 is pushed by the small spring 57. The frosted pad 55 at the bottom of the arc plate 54 limits the adjustment disk 53 and fixes the size of the ear hook rope 1, thereby improving the problem that some patients need to maintain a certain looseness when using it to increase comfort. Then, the gastric tube is placed in the gastric tube retention port 62 by pulling the annular disk 64, and then, under the push of the telescopic spring 66, the concave surface of the scale tooth 65 on the annular disk 64 is fitted and engaged with the surface of the gastric tube to limit the position of the gastric tube. When it is necessary to fine-tune the front and back of the gastric tube, when the annular disk 64 is rotated by a person, the surface of the gastric tube is squeezed, which drives the slider 63 to move backward to squeeze the telescopic spring 66. At the same time, the annular disk 64 rotates to drive the scale tooth 65 to move the outer surface of the gastric tube back and forth.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
