Description

Technical Field

[0001] This utility model relates to the field of intubation assistance technology, and in particular to an auxiliary fixation device for endotracheal intubation. Background Technology

[0002] The main functions of endotracheal intubation fixation devices are as follows: to firmly fix the endotracheal tube in the appropriate position, preventing it from shifting, dislodging, or going deeper, ensuring the stability of the endotracheal tube position, maintaining an effective airway, and preventing changes in the position of the endotracheal tube due to external traction during turning or other medical procedures. Through reasonable fixation methods, pressure is evenly distributed, reducing the pressure and friction of the endotracheal tube on the mucous membranes of the patient's mouth, nose, and throat, reducing the risk of complications such as local tissue damage, ulceration, and bleeding. It can prevent oral mucosal damage and pharyngeal mucosal congestion and edema caused by long-term friction from the tube. Existing devices cannot prevent patients from unconsciously biting the trachea, which could obstruct oxygen delivery.

[0003] However, existing technologies, such as Chinese Publication No. CN220558385U, "An Auxiliary Fixation Device for Endotracheal Intubation," relate to the field of medical device technology, specifically an auxiliary fixation device for endotracheal intubation. This auxiliary fixation device includes a fixation plate A, a fixation plate B, a slide rail plate, elastic bands, connecting ropes, a fixing device, and an adhesive layer. The two ends of the slide rail plate are fixedly connected to the fixation plates A and B. The other ends of the fixation plates A and B are respectively connected to one end of the elastic band, and the other ends of the two elastic bands are respectively fixed to the connecting rope. The fixing device is slidably connected to the slide rail plate. An adhesive layer is fixedly provided on the back of both the fixation plates A and B. This solution addresses the problem that existing endotracheal tubes are not of a single size, and different sizes of endotracheal tubes are used by patients of different genders and ages. Existing devices cannot clamp and fix tubes of different sizes, making them inconvenient to use.

[0004] However, this device does not have a retractable mouthguard. Different patients have different oral cavity sizes, depths, and occlusions. A non-retractable mouthguard cannot be adjusted according to the patient's specific oral cavity structure, and cannot ensure that the mouthguard is accurately placed in the right position. It cannot open the oral cavity, which may lead to unstable fixation due to differences in oral cavity structure or damage to oral tissues. Patients may unconsciously bite down on the trachea, resulting in obstruction of oxygen delivery. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the differences in oral cavity size, depth and occlusion among different patients, the inability of non-stretchable mouthguards to be adjusted according to the specific oral structure of the patient, the inability to ensure that the mouthguard can be accurately placed in the right position, the inability to open the oral cavity, the resulting instability due to differences in oral structure or damage to oral tissues, and the patient unconsciously biting down on the trachea, resulting in obstruction of oxygen delivery.

[0025] In this embodiment, the oxygen tube is passed through the mouthguard 2 and the liner 15, and the other end of the oxygen tube is inserted into the patient's body at a suitable position. Then, the position of the mouthguard 2 in the patient's mouth is adjusted according to the depth and size of the patient's mouth. The position allows the mouthguard 2 to move inside the auxiliary mask 1. After moving to the appropriate position, it can be rotated on the outer surface of the threaded groove 9 by the tightening ring 10. Under the action of the stress groove 8, the tightening sleeve 7 will begin to tighten and fix the position of the mouthguard 2. Then, the mouthguard 2 is placed in the patient's mouth. By pulling the Velcro strip 3 at the position of the buckle 4, the length of the Velcro strip 3, the connecting strip 5 and the protective plate 6 is adjusted to wear the device. Then, the second knob 23 drives the power rod 22 to rotate inside the mouthguard 2.
