Description
技术领域technical field
本实用新型涉及医疗器械制造技术领域，尤其是一种可以持续充气的气管插管。The utility model relates to the technical field of medical device manufacturing, in particular to a tracheal intubation tube which can be continuously inflated.
背景技术Background technique
气管插管是将一特制的气管内导管经患者声门置入气管的插管，为重症患者的气道通畅、通气供氧、呼吸道吸引和防止误吸等提供最佳条件。现有的气管插管一般包括弯曲的管体，管体的一端安装有接头，另一端开口前套有一用于插入患者气管内的气囊，以支撑患者气管内壁，有一充气管穿过伸入气囊内，以为气囊充气，保证气囊进入患者气管内一直保持特定的压力值（25～30cmH2O），压力过高会影响气道黏膜供血，研究结果显示，当气囊压超过30cmH2O时，黏膜毛细血管血流开始减少；当气囊压超过50cmH2O时，血流完全被阻断。气管黏膜压迫超过一定时间，将导致气管黏膜缺血性损伤甚至坏死，严重时可发生气管食管瘘；相反，如果气囊压力不足，气囊与充气管连接处无法密闭，患者上呼吸道的分泌物容易掉进肺部，导致机械通气漏气、误吸、呼吸机相关性肺炎等。且要维持气囊压力在正常范围，需要每6至8小时测量压力1次，耗费人力资源，工作效率大受影响。Tracheal intubation is an intubation in which a special endotracheal tube is inserted into the trachea through the patient's glottis, providing the best conditions for airway patency, ventilation and oxygen supply, airway suction and prevention of aspiration in critically ill patients. Existing tracheal intubation generally includes a curved tube body, one end of the tube body is provided with a joint, the other end is open and covered with a balloon for inserting into the patient's trachea to support the inner wall of the patient's trachea, and an inflation tube passes through and extends into the balloon. It is believed that the air bag is inflated to ensure that the air bag enters the patient's trachea and maintains a specific pressure value (25-30 cmH 2 O). If the pressure is too high, it will affect the blood supply of the airway mucosa. The research results show that when the air bag pressure exceeds 30 cmH 2 O, the Capillary blood flow begins to decrease; when the balloon pressure exceeds 50 cmH2O , blood flow is completely blocked. Tracheal mucosal compression for more than a certain period of time will lead to ischemic damage or even necrosis of the tracheal mucosa, and tracheoesophageal fistula may occur in severe cases; on the contrary, if the pressure of the air bag is insufficient, the connection between the air bag and the inflatable tube cannot be sealed, and the secretions from the upper respiratory tract of the patient are easy to fall off. into the lungs, resulting in mechanical ventilation leakage, aspiration, ventilator-associated pneumonia, etc. In addition, to maintain the airbag pressure in the normal range, it is necessary to measure the pressure every 6 to 8 hours, which consumes human resources and greatly affects the work efficiency.

本能持续充气的气管插管采用充气管的外加气囊，即控压气囊，和充气管及气囊为一密闭的空间，使气囊不再漏气；使用前，气囊和控压气囊内均没有足够的气体使它们鼓起，使用时，本插管的气囊部位进入患者气管，充气设备连接控压气囊上的充气接头，控压气囊和气囊均充气鼓起，在充气到气囊压力最佳值后，停止充气，由于气囊、控压气囊及充气管不漏气，气囊内的气压保持不变，只有在患者姿势变化而气管内压有微变化时，气囊压力略大，则气体自动被压到控压气囊内，控压气囊体积变大一点，气囊压力略小，控压气囊的气体进入气囊，控压气囊体积变小一点，需要增加较大压力时，才需开启充气设备充气，很好地解决了气囊内压力控制难的问题，无需使用单向放气阀，同时又解决了空气资源浪费、充气设备能耗高的问题；充气管经管体管壁内过，在选用硅胶材料做充气管时，充气管不会体积膨胀太多，且整体结构简单，解决了现有气管插管结构复杂，使用不便的问题；The tracheal intubation that can be continuously inflated adopts the external air bag of the inflatable tube, that is, the pressure control air bag. The gas makes them inflate. When in use, the airbag part of the intubation enters the patient's trachea, and the inflation device is connected to the inflation connector on the pressure control airbag. Both the pressure control airbag and the airbag are inflated and inflated. Stop inflation, because the air bag, the pressure control air bag and the inflation tube do not leak, the air pressure in the air bag remains unchanged. Only when the patient's posture changes and the intratracheal pressure changes slightly, the air bag pressure is slightly larger, and the gas is automatically pressed to the control. In the pressure air bag, the volume of the pressure control air bag becomes larger, and the pressure of the air bag is slightly smaller. The gas of the pressure control air bag enters the air bag, and the volume of the pressure control air bag becomes smaller. When a larger pressure needs to be increased, the inflation device needs to be opened to inflate. It solves the problem of difficult pressure control in the airbag, without the need to use a one-way deflation valve, and at the same time solves the problems of waste of air resources and high energy consumption of inflatable equipment; the inflation tube passes through the tube wall of the tube body, and the silicone material is used as the inflation tube. When the inflatable tube is not too large, the overall structure is simple, which solves the problems of complicated structure and inconvenient use of the existing tracheal intubation tube;
本能持续充气的气管插管可以持续地将气囊压力稳定在25～30cmH2O，无需另外增加人力控制，极大地提高了工作效率，且使用方便，制造成本低、能耗低，可以广泛用于重症监护的临床应用。The tracheal intubation that can be inflated continuously can continuously stabilize the air bag pressure at 25-30 cmH 2 O without additional human control, which greatly improves the work efficiency, and is easy to use, with low manufacturing cost and low energy consumption, and can be widely used in Clinical application of intensive care.
