Description

气管插管牙垫Endotracheal intubation mouth guard

技术领域Technical field

本实用新型属于医疗器具技术领域,具体涉及一种气管插管牙垫。The utility model belongs to the technical field of medical instruments, and specifically relates to a tracheal intubation dental pad.

背景技术Background technique

气管插管是指将一特制的气管内导管经声门置入气管的技术,在危重病人的抢救中发挥了重要作用,为治疗呼吸骤停、气道阻塞、缺氧或通气不足等提供良好条件。气管插管牙垫是患者在进行治疗过程中,咬在嘴中起到固定气管作用的部件,通过牙垫的设置不仅方便对气管的放置,还能够避免咬到气管。Tracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. It plays an important role in the rescue of critically ill patients and provides an excellent treatment for respiratory arrest, airway obstruction, hypoxia or insufficient ventilation. condition. The tracheal intubation bite pad is a component that the patient bites in his mouth to fix the trachea during treatment. The setting of the brace not only facilitates the placement of the trachea, but also prevents biting of the trachea.

传统的气管插管固定方式是,在气管插管插入完毕后,将牙垫置入患者的上下门齿之间,将牙垫和气管插管用胶布固定后,通过胶布将气管插管和牙垫呈X型固定于嘴四周,但是这种胶带粘贴固定的方式,操作流程繁琐,耗费大量时间,效率低下。随着技术的进步,目前在各大医院逐渐摒弃了使用胶带固定的方式,而改为在牙垫的固定板两侧设置头带,通过使头带绕在病人头颈部以实现对气管插管和牙垫的固定的方式。这种方式有效解决了使用胶布固定的弊端,但是其头带固定在头颈的后方,影响耳科、神经外科小脑手术、骨科颈椎手术等在头颈部两侧和后侧的操作,且头带固定在病人头颈上使病人有受勒的感觉,容易发生窜动,固定效果不佳。The traditional way of fixing the endotracheal tube is to place the dental pad between the patient's upper and lower incisors after the endotracheal tube is inserted, fix the dental pad and the endotracheal tube with tape, and then use the tape to secure the endotracheal tube and the dental pad. It is fixed around the mouth in an X shape, but this method of tape fixation is cumbersome, time-consuming and inefficient. With the advancement of technology, major hospitals have gradually abandoned the use of adhesive tape for fixation, and instead set headbands on both sides of the fixed plate of the dental pad. The headbands are wrapped around the patient's head and neck to achieve tracheal intubation. The way tubes and braces are fixed. This method effectively solves the disadvantages of using tape for fixation, but the headband is fixed at the back of the head and neck, which affects operations on both sides and back of the head and neck such as otology, neurosurgery, cerebellar surgery, and orthopedic cervical spine surgery, and the headband Fixing it on the patient's head and neck makes the patient feel like it is being strangled, and it is prone to movement and the fixation effect is poor.
