具体实施方式detailed description
下面结合具体附图和实施例对本实用新型作进一步说明。Below in conjunction with specific accompanying drawing and embodiment the utility model is further described.
如图1、图2及图3所示，所述一种多功能鼻咽通气道，使用时经一侧鼻孔开口沿鼻咽通道置入，直至口部到达患者声门开口处。包括鼻咽通气道本体1和埋设在鼻咽通气道本体1管壁内的内通管2，所述内通管2头端出鼻咽通气道本体1头端内侧管壁连通设置游离管21。所述游离管21位于鼻咽通气道本体1内腔且游离管21头端设置若干内开口20指向鼻咽通气道本体1头端。内通管2尾端出鼻咽通气道本体1尾端外侧管壁连通设置内连接管22，内连接管22尾端设置内通接口23。As shown in Figures 1, 2 and 3, the multifunctional nasopharyngeal airway is inserted through the opening of one nostril along the nasopharyngeal passage until the mouth reaches the opening of the patient's glottis. It includes a nasopharyngeal airway body 1 and an internal tube 2 embedded in the wall of the nasopharyngeal airway body 1 . The free tube 21 is located in the inner cavity of the nasopharyngeal airway body 1 and the head end of the free tube 21 is provided with several inner openings 20 pointing to the head end of the nasopharyngeal airway body 1 . The tail end of the internal communication pipe 2 exits the outer tube wall of the nasopharyngeal airway body 1 and is connected with an inner connecting pipe 22 , and the inner connecting pipe 22 is provided with an internal communication interface 23 at the tail end.
所述游离管21为质地较硬韧性较强的管体，优选设置在鼻咽通气道本体1内腔中部截面的中间位置，所述游离管21的前端管腔，优选与鼻咽通气道本体1的内腔平行，所述内开口20指向鼻咽通气道本体1头端。如此，当通过内通接口23向鼻咽通气道本体1腔内给药时，药物能迅速进入气道；当内通接口23连接二氧化碳分析仪时，位于管腔中央朝向鼻咽通气道本体1头端的内开口20能迅速采集患者呼气末气体样本，从而对患者呼吸状态作出判断；当患者自主呼吸时，也可在内通接口23连接氧气管，实现患者气道深部吸氧，吸氧效果极佳。The free tube 21 is a tube body with a relatively hard and tough texture, and is preferably arranged in the middle of the middle section of the nasopharyngeal airway body 1. The front lumen of the free tube 21 is preferably connected to the nasopharyngeal airway body. The inner cavity of the nasopharyngeal airway body 1 is parallel, and the inner opening 20 points to the head end of the nasopharyngeal airway body 1 . In this way, when the drug is administered into the cavity of the nasopharyngeal airway body 1 through the internal communication interface 23, the drug can quickly enter the airway; The inner opening 20 at the head end can quickly collect the patient's end-tidal gas sample, so as to make a judgment on the patient's breathing state; when the patient breathes spontaneously, the internal communication interface 23 can also be connected to the oxygen tube to realize the deep oxygen inhalation of the patient's airway, The effect is excellent.
所述内通接口23外侧管壁与二氧化碳采样管内腔匹配。便于连接二氧化碳采样管完成呼气末二氧化碳监测。需要吸氧时，也可将吸氧管衔接在内通接口23，即可方便实现气道深部吸氧，吸氧效果好。The outer tube wall of the internal communication interface 23 matches the inner cavity of the carbon dioxide sampling tube. It is convenient to connect the carbon dioxide sampling tube to complete the end-tidal carbon dioxide monitoring. When oxygen inhalation is needed, the oxygen inhalation tube can also be connected to the internal communication interface 23, so that the deep oxygen inhalation of the airway can be realized conveniently, and the oxygen inhalation effect is good.
当然，必须的，在内连接管22设置能关闭内连接管22的开关，或在内通接口23接口附近设置能密封内通接口23的塞体或盖体。在不使用内通管2时，能关闭内通管2，一定程度上能避免气管导管本体1通气时漏气。Of course, it is necessary that the inner connecting pipe 22 is provided with a switch capable of closing the inner connecting pipe 22, or a plug or a cover capable of sealing the inner connecting port 23 is arranged near the inner connecting port 23 interface. When the inner tube 2 is not in use, the inner tube 2 can be closed to avoid air leakage during ventilation of the endotracheal tube body 1 to a certain extent.
如图2及图3所示，所述鼻咽通气道本体1尾端连接设置呼吸接口3，与呼吸机螺纹管呼吸支持接口匹配。并在鼻咽通气道本体1附近设置用于堵塞患者一侧鼻孔的鼻塞体4。As shown in FIG. 2 and FIG. 3 , the tail end of the nasopharyngeal airway body 1 is connected with a respiratory interface 3 , which matches the respiratory support interface of the threaded tube of the ventilator. And near the nasopharyngeal airway body 1, a nasal plug 4 for blocking the nostril on one side of the patient is arranged.
当患者因舌体过于肥大堵塞上呼吸道导致呼吸受阻后，经一侧鼻孔将本实用新型插到声门口，可在鼻咽通气道本体1尾端的呼吸接口3连接呼吸机螺纹管路，实施呼吸机械通气，鼻咽通气道本体1起到通气管道的作用。此时，肥大的舌体起到了堵塞口腔部位裂隙的作用，能避免气体经口腔部泄漏。但此时的呼吸通路密闭性很差，因为咽喉腔与另一侧鼻孔连通，气体会经另一侧鼻孔快速逸出。若将鼻塞体4堵塞在另一侧鼻孔开口处，人工建立的呼吸通路密闭性大大增加，机械通气的效果将更好。但需注意的是：实施机械通气时潮气量和气道压不宜过大，否则气体容易进入患者胃腔内，可能导致呕吐返流误吸，引起不良事件。When the patient's breathing is obstructed due to the blockage of the upper airway due to the excessive hypertrophy of the tongue, the utility model can be inserted into the glottis through one nostril, and the breathing interface 3 at the tail end of the nasopharyngeal airway body 1 can be connected to the threaded pipeline of the ventilator to perform breathing. For mechanical ventilation, the nasopharyngeal airway body 1 functions as a ventilation channel. At this time, the hypertrophy of the tongue plays a role in blocking the cracks in the oral cavity, which can prevent gas from leaking through the oral cavity. But at this time, the airtightness of the breathing passage is very poor, because the throat cavity is connected with the other nostril, and the gas will quickly escape through the other nostril. If the nasal plug body 4 is blocked at the opening of the nostril on the other side, the airtightness of the artificially established breathing passage will be greatly increased, and the effect of mechanical ventilation will be better. However, it should be noted that the tidal volume and airway pressure should not be too large during mechanical ventilation, otherwise the gas will easily enter the gastric cavity of the patient, which may cause vomiting, reflux and aspiration, and cause adverse events.
如图3所示，所述鼻咽通气道本体1对应患者鼻后孔口腔内部位设置固定气囊5，并连通固定气囊5在鼻咽通气道本体1内设置充气管51，充气管51在鼻咽通气道本体1尾段连通设置外充气管52，外充气管52尾端连通设置压力感受气囊53，连通压力感受气囊53设置压力阀充气口54。As shown in Figure 3, the nasopharyngeal airway body 1 is provided with a fixed air bag 5 corresponding to the position in the oral cavity of the patient's posterior nasal cavity, and is connected with the fixed air bag 5 to set an inflatable tube 51 in the nasopharyngeal airway body 1. The tail section of the pharyngeal airway body 1 is connected with an external inflation tube 52, and the tail end of the outer gas tube 52 is connected with a pressure sensing air bag 53, and the pressure sensing air bag 53 is connected with a pressure valve inflation port 54.
所述鼻咽通气道本体1置入患者鼻咽通道内，患者由于不适可能会有呛咳动作，或呕吐动作，伴随这种反抗的动作，鼻咽通气道本体1会慢慢滑出鼻腔腔道。在鼻咽通气道本体1对应患者鼻后孔口腔内部位设置固定气囊5，通过连通的充气管51、外充气管52及压力阀充气口54能对置入患者鼻咽通道内的鼻咽通气道本体1的固定气囊5充入气体，饱胀的固定气囊5体积远远大于鼻腔后鼻孔的孔径，能对鼻咽通气道本体1起到固定作用。而压力感受气囊53与固定气囊5连通，压力相同，通过感受压力感受气囊53的压力，能对固定气囊5的气体压力做出判断。同时，固定气囊5充入气体后能对鼻咽通气道本体1周围和口腔的间隙起到封堵作用，进一步增强鼻咽通气道本体1实施机械通气时的密闭性。The nasopharyngeal airway body 1 is placed in the patient's nasopharyngeal passage, and the patient may cough or vomit due to discomfort. With this resistance action, the nasopharyngeal airway body 1 will slowly slide out of the nasal cavity road. A fixed air bag 5 is set in the nasopharyngeal airway body 1 corresponding to the patient's posterior nasal cavity, and the nasopharynx inserted into the patient's nasopharyngeal passage can be ventilated through the connected inflatable tube 51, external inflatable tube 52 and pressure valve inflatable port 54 The fixed airbag 5 of the airway body 1 is filled with gas, and the volume of the inflated fixed airbag 5 is much larger than the aperture of the posterior nostril of the nasal cavity, which can fix the nasopharyngeal airway body 1 . The pressure-sensing airbag 53 communicates with the fixed airbag 5, and the pressure is the same. By feeling the pressure of the pressure-sensing airbag 53, the gas pressure of the fixed airbag 5 can be judged. At the same time, after the fixed airbag 5 is filled with gas, it can seal the gap between the nasopharyngeal airway body 1 and the oral cavity, further enhancing the airtightness of the nasopharyngeal airway body 1 during mechanical ventilation.
总之，本实用新型通过在鼻咽通气道本体1设置内通管2，能经鼻咽通气道内腔吸氧、能连接二氧化碳分析仪监测患者呼气末二氧化碳浓度；在鼻咽通气道本体1尾部设置呼吸接口3，能连接呼吸机，配合鼻塞体4堵塞另外一侧鼻孔，能对患者实施呼吸支持；通过固定气囊5能起到固定作用，同时也能增强机械通气的密闭性。其结构简单，成本低廉，使用方便，安全可靠。In a word, the utility model can inhale oxygen through the inner cavity of the nasopharyngeal airway by setting the inner tube 2 on the nasopharyngeal airway body 1, and can connect a carbon dioxide analyzer to monitor the patient's end-tidal carbon dioxide concentration; The respiratory interface 3 is provided, which can be connected to a ventilator, and the nasal plug body 4 can be used to block the nostril on the other side, so as to provide respiratory support for the patient; the fixed airbag 5 can play a fixed role, and can also enhance the airtightness of the mechanical ventilation. The utility model has the advantages of simple structure, low cost, convenient use, safety and reliability.
