Description

一种多功能鼻咽通气导管A multifunctional nasopharyngeal ventilation catheter

技术领域technical field

本实用新型涉及医疗器械技术领域,特别是涉及一种多功能鼻咽通气导管。The utility model relates to the technical field of medical devices, in particular to a multifunctional nasopharyngeal ventilation catheter.

背景技术Background technique

作为急救中常用的一种抢救手段,气管插管术是呼吸道管理中应用最广泛、最有效最快捷的手段之一,是医务人员必须熟练掌握的基本技能。文献报道困难的气管插管的发生率在1.5%~13%,并且困难插管更有可能发生在手术室以外的次优环境中,如急诊室、重症监护病房(ICU)、病人病房,甚至医院外。而经鼻清醒插管气则是处理困难气道最有效的方法。As a commonly used rescue method in first aid, tracheal intubation is one of the most widely used, most effective and quickest methods in airway management, and is a basic skill that medical staff must master. The reported incidence of difficult endotracheal intubation ranges from 1.5% to 13%, and difficult intubation is more likely to occur in suboptimal settings outside the operating room, such as emergency rooms, intensive care units (ICUs), patient wards, and even outside the hospital. Awake nasal intubation is the most effective way to deal with difficult airways.

气管插管过程中,由于气管插管导管的结构特点和设计缺点,有可能引起如喉头水肿、声门损伤、口腔内损伤、呼吸道损伤、局部出血等并发症,想要降低这一系列并发症的发生几率,采用可视化气管插管是一个好的选择。In the process of tracheal intubation, due to the structural characteristics and design shortcomings of the tracheal intubation catheter, complications such as laryngeal edema, glottis injury, intraoral injury, respiratory tract injury, and local bleeding may occur. The probability of occurrence, the use of visual tracheal intubation is a good choice.

气管插管用于手术前对患者进行麻醉后,在临床使用中,可能因套管内湿化不足、吸痰方法不得当、患者咳痰无力、体液不足造成痰液粘稠等多种原因,以致痰液长时间附着在气切气道管壁,堆积过多从而形成痰痂。目前临床对这种情况的处理方式是:在气管插管开口滴入0.5ml生理盐水后,用吸痰管由近及远地沿气管插管吸出气道和插管里的分泌物。由于气管插管的内径为圆形,且其长度达250mm和一定的弧度,滴入的生理盐水从高位往低位流;同时,无法任意吸取贴在气管壁上的分泌物,无法做到有效清洁。After tracheal intubation is used to anesthetize patients before surgery, in clinical use, there may be various reasons such as insufficient humidification in the cannula, inappropriate sputum suction methods, inability of patients to expectorate sputum, and lack of body fluids resulting in viscous sputum. The sputum adheres to the wall of the tracheostomy airway for a long time and accumulates too much to form a sputum scab. The current clinical treatment for this situation is as follows: after instilling 0.5ml of normal saline into the opening of the tracheal intubation, use a sputum suction tube to suck out the secretions in the airway and intubation from near and far along the tracheal intubation. Because the inner diameter of the tracheal intubation tube is circular, and its length is 250mm and a certain arc, the dripped physiological saline flows from a high position to a low position; at the same time, it is impossible to arbitrarily absorb the secretions sticking to the tracheal wall, and it cannot be effectively cleaned. .

现阶段临床上的经鼻气管插管常通过可视喉镜或纤维支气管镜来进行引导插管,其操作较为复杂,且成本较为高昂,在众多基层医院较难普及。再者,现有的气管导管功能不够完善,医护人员在进行插管相关操作时可能需要使用不同器械分步进行操作来进行吸痰和气体监测等,步骤较为繁琐,并且在这一过程中可能产生感染或增加其他并发症的发生率。At present, the clinical nasotracheal intubation is often guided by a video laryngoscope or a fiberoptic bronchoscope. The operation is relatively complicated and the cost is relatively high, which is difficult to popularize in many primary hospitals. Furthermore, the function of the existing tracheal tube is not perfect, and medical staff may need to use different instruments to perform operations in steps to perform sputum suction and gas monitoring when performing intubation-related operations. produce infection or increase the incidence of other complications.

First, connect the wireless micro-camera to a slender steel cable and place it in the tracheal intubation tube. After the patient is subjected to surface anesthesia of the nasopharyngeal mucosa, the transnasal visual ventilation tube 1 is intubated. Insert, by pulling the bellows cable 7, adjust the bending degree of the bellows 31 at the front end of the ventilation tube 1 to adapt to the patient's nasal cavity and airway anatomical structure characteristics. The micro camera is taken out, then the balloon 22 is inflated, and the cannula is fixed. If the patient's nasal cavity is blocked by a foreign body or has abnormal breathing, the suction tube negative pressure connector 5 at the end of the sputum suction tube 24 can be connected to perform sputum suction. After the intubation is successful, connect the air bag gas injection port 8 to the external sensor air bag pressure detection device, adjust the pressure of the air bag 22 to a suitable pressure, inject air, and fix the catheter. The ventilator is connected to the ventilator through the upper port 9 of the ventilation tube, the gas monitoring tube 6 is connected to the gas monitor, and other functions are adopted according to the specific conditions of the patient.

When the tracheal intubation is finally removed, the airbag needs to be pumped. At this time, the remaining sputum still accumulates in the sputum accumulation tank and is taken out of the trachea with the tracheal intubation, and will not splash into the trachea and cause infection.
