Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, it relates to a tracheal intubation fixator for the intensive care unit. Background Art

[0002] In the clinical treatment of the intensive care unit, tracheal intubation is an important means to maintain the respiratory function of patients. Tracheal intubation is a method of inserting a special endotracheal tube through the oral cavity or nasal cavity and into the trachea or bronchus through the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, airway suction, etc., and is an important measure to rescue patients with respiratory dysfunction.

[0003] Currently, the commonly used tracheal intubation fixation methods in clinical practice mainly include fixation with medical tape and fixation with a tracheal intubation fixator. The medical tape is used to paste and fix the intubation on the patient's face. The tape fixation method has many drawbacks. For example, it is easily affected by the patient's sweat and oral secretions, resulting in a decrease in adhesion, unstable fixation effect, and frequent replacement of the tape will cause irritation and damage to the patient's facial skin, causing allergic reactions such as redness and blisters in the patient; the traditional fixator has a single structure, is difficult to accurately adapt to the facial contours and tracheal intubation models of different patients, lacks multi-angle limitation of the tracheal intubation during the fixation process, cannot effectively prevent the intubation from twisting and slipping, and may also cause complications such as airway mucosal damage and pressure sores due to excessive local pressure, increasing the patient's pain and infection risk and affecting the treatment effect. Therefore, it is of great clinical significance to develop a safe, comfortable, stable and highly adaptable tracheal intubation fixator. Summary of the Invention

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A tracheal intubation fixator for the intensive care unit includes an elastic band, a left body and a right body. The left body and the right body are detachably connected to each other on the adjacent sides, and fixing rotating rods are provided on the other sides of the left body and the right body; the left body is provided with a left facial fitting plate movably connected to the fixing rotating rod, and the right body is provided with a right facial fitting plate movably connected to the fixing rotating rod; the two ends of the elastic band are respectively connected to the ends of the left facial fitting plate and the right facial fitting plate; a through fixing hole is provided in the middle of the connection part of the left body and the right body, and a fixing component is provided at the fixing hole of the left body and the right body for fixing the tracheal intubation.

[0006] By adopting the above technical solutions, through the elastic straps and the movable left and right facial fitting plates, it can adapt to the facial contours of different patients, automatically adjust the fitting degree according to the patient's facial contour, avoid the hard extrusion of traditional fixators, and improve the wearing comfort and fixation stability.

When in use, pull the pull ring, pull out the moving rod to drive the moving plate to move and compress the spring, and the sliding rod keeps the moving plate moving in parallel, so that the distance between the movable splint and the clamping seat increases. After releasing the pull ring, under the action of the spring restoring force, the tracheal intubation is clamped and fixed between the clamping seat and the movable splint. This clamping structure adapts to intubations of different diameters for clamping and fixing.
