本实用新型涉及医疗器械的技术领域，特别是一种新型气管插管。The utility model relates to the technical field of medical instruments, in particular to a novel endotracheal cannula.
背景技术Background technique
气管插管作为医院麻醉科、急诊科和喉科必备器械，已经越来越广泛地被使用。一般是通过口腔或鼻腔将气管插管插入病人的气管内，从而达到快速抢救呼吸道阻塞或呼吸停止的病人的目的，或者给无法自主呼吸的患者进行供氧。As an essential device for the anesthesiology, emergency and laryngology departments of hospitals, endotracheal intubation has been used more and more widely. Generally, the endotracheal intubation is inserted into the patient's trachea through the mouth or nose, so as to quickly rescue patients with airway obstruction or respiratory arrest, or to provide oxygen to patients who cannot breathe independently.
一般气管插管包括插管和插管接头，插管插置于人体内，为了提供更灵活的连接，插管接头通常连接到一个灵活的导管支架，而导管支架又通过三通接头连通呼吸系统。三通管的一端连通导管支架，三通管的另外两端的一端接呼吸机输送氧气的进气管，另一端接出气管而连通外界。但是，由于现有的插管的进气腔和出气腔都是同一个腔体，在患者呼气的过程中，人体内产生的二氧化碳会残留于插管的腔体内，从而在气管插管内产生生理无效腔，即下一次进气时的氧气与残留的二氧化碳混合，会使进入人体的氧气浓度下降，使得实际供氧的氧气浓度与医生预估的氧气浓度不相匹配。现有的解决病人的气管插管生理无效腔的操作，一般是需要医生根据根据实际经验对供氧浓度进行适度地上调，十分考验医生的临床经验，不利于对患者的准确供氧和救治，而且实质上是无法完全去除气管插管的生理无效腔。Generally, the tracheal cannula includes a cannula and a cannula joint. The cannula is inserted into the human body. In order to provide a more flexible connection, the cannula joint is usually connected to a flexible catheter bracket, and the catheter bracket is connected to the respiratory system through a three-way joint. One end of the three-way tube is connected to the catheter bracket, and one end of the other two ends of the three-way tube is connected to the inlet pipe of the ventilator to deliver oxygen, and the other end is connected to the outlet pipe to connect to the outside world. However, since the inlet cavity and the outlet cavity of the existing cannula are the same cavity, during the patient's exhalation, the carbon dioxide produced in the human body will remain in the cavity of the cannula, thereby generating a physiological dead space in the tracheal cannula, that is, the oxygen mixed with the residual carbon dioxide during the next intake will reduce the oxygen concentration entering the human body, so that the actual oxygen concentration of oxygen supply does not match the oxygen concentration estimated by the doctor. The existing operation to solve the physiological dead space of the patient's tracheal cannula generally requires the doctor to moderately increase the oxygen supply concentration based on actual experience, which is very challenging for the doctor's clinical experience, is not conducive to the accurate oxygen supply and treatment of the patient, and is essentially unable to completely remove the physiological dead space of the tracheal cannula.

This ensures that the oxygen concentration of the air intake pipe gas that directly enters the lungs remains unchanged, which can solve the problem of the physiological dead space of the endotracheal cannula, and can be adapted for use with the existing endotracheal cannula, thereby reducing the modification cost and production cost of the product.

由此，以使得本实用新型的一种新型气管插管100形成有双腔结构，并且该双腔结构的插管子管6的腔室独立连通出气接头73和出气导管8，出气导管8用于连接呼吸系统（图未示）的呼吸机的出气管而连通外界，而插管1的腔室独立连通进气接头74和进气导管9，进气导管9连通呼吸机输送氧气的进气管，即，可通过插管1的腔室进气输氧，通过插管子管6的腔室出气换气。本实用新型基于现有气管插管30进行改造，使进气和出气分为两个独立的腔室，在肺部出气时，呼吸机的进气管的进气阀关闭，但进气管和插管1的腔室内有气体残留和气压存在，肺部内气体只能从出气管和插管子管6的腔室经出气管输出到外界，而不会进入插管1的腔室，由此保障了下次进气时直接进入到肺部的气体的氧浓度不变，可解决气管插管30的生理无效腔问题，并且可适配现有的气管插管30使用，降低产品的改造成本。同时，虽然现有技术中已存在双腔的气管插管，但现有技术的双腔插管结构完全不同于本实用新型的结构，并且该双腔插管结构的用途一般是在胸外科手术中，隔离并选择性地不通气一个肺，就导致该现有的双腔插管结构的两个末端一个位于支气管内一个位于主气管，无法直接解决本实用新型的生理无效腔的问题。Thus, a new type of endotracheal cannula 100 of the utility model is formed with a double-cavity structure, and the cavity of the cannula sub-tube 6 of the double-cavity structure is independently connected to the air outlet connector 73 and the air outlet duct 8, the air outlet duct 8 is used to connect to the air outlet pipe of the ventilator of the respiratory system (not shown) and connect to the outside world, and the cavity of the cannula 1 is independently connected to the air inlet connector 74 and the air inlet duct 9, the air inlet duct 9 is connected to the air inlet pipe of the ventilator for delivering oxygen, that is, oxygen can be delivered through the cavity of the cannula 1, and air can be delivered through the cavity of the cannula sub-tube 6. The utility model is modified based on the existing tracheal cannula 30, so that the air intake and air outlet are divided into two independent chambers. When the lungs are out of air, the air intake valve of the air intake pipe of the ventilator is closed, but there is gas residue and air pressure in the chambers of the air intake pipe and the cannula 1. The gas in the lungs can only be output to the outside through the air outlet pipe and the chamber of the cannula sub-tube 6 through the air outlet pipe, and will not enter the chamber of the cannula 1. This ensures that the oxygen concentration of the gas directly entering the lungs during the next air intake remains unchanged, which can solve the physiological dead space problem of the tracheal cannula 30, and can be adapted to the existing tracheal cannula 30 for use, reducing the modification cost of the product. At the same time, although double-lumen tracheal cannulas already exist in the prior art, the double-lumen cannula structure of the prior art is completely different from the structure of the utility model, and the purpose of the double-lumen cannula structure is generally to isolate and selectively not ventilate one lung in thoracic surgery, which results in the two ends of the existing double-lumen cannula structure being located in the bronchus and the main trachea, respectively, and cannot directly solve the physiological dead space problem of the utility model.
本实施例中，为了防止痰液等异物向外堵塞新型气管插管100，同时由于一般在呼气时才会存在异物堵塞的问题，因此将上述的吸痰接头10设置连通于出气接头73，进而连通插管子管6，用于伸置吸痰管对痰液进行吸出。当然，该吸痰接头也可用于伸置纤维支气管镜等器械，以对人体内部进行观察、组织取样等等。In this embodiment, in order to prevent foreign matter such as sputum from blocking the new endotracheal tube 100, and because the problem of foreign matter blocking generally occurs during exhalation, the sputum suction connector 10 is connected to the air outlet connector 73, and then connected to the intubation sub-tube 6, so as to extend the sputum suction tube to suck out the sputum. Of course, the sputum suction connector can also be used to extend instruments such as fiber bronchoscopes to observe the inside of the human body, take tissue samples, etc.
具体的，外套筒71包括中空圆柱状套接端711和向外直径渐缩的中空锥台状连接端712，所述连接端712的锥台侧壁7121周向间隔的设置该出气接头73和进气接头74，进气接头74与套接端713的外腔室713连通，而内接管72远离插接部721的一端具有折弯段723和直线段724，折弯段723连接连通于该出气接头74，使出气接头74与内接管72的内腔室722连通。而所述吸痰接头10同轴连接设于连接端712的外端，并且直线连通于内接管72的直线段724，进而直线连通插接端721。Specifically, the outer sleeve 71 includes a hollow cylindrical sleeve end 711 and a hollow frustum-shaped connection end 712 with a gradually decreasing diameter outward, and the frustum side wall 7121 of the connection end 712 is provided with the outlet connector 73 and the inlet connector 74 at intervals in the circumferential direction, and the inlet connector 74 is connected to the outer chamber 713 of the sleeve end 713, and the end of the inner pipe 72 away from the plug-in portion 721 has a bending section 723 and a straight section 724, and the bending section 723 is connected to the outlet connector 74, so that the outlet connector 74 is connected to the inner chamber 722 of the inner pipe 72. The sputum suction connector 10 is coaxially connected to the outer end of the connection end 712, and is linearly connected to the straight section 724 of the inner pipe 72, and then linearly connected to the plug-in end 721.
由此，吸痰管或纤维支气管镜可从吸痰接头10直插进入内接管72和插管子管6。所述吸痰接头10上设有封口塞101，用于不使用时对吸痰接头10进行密封封闭。Thus, the sputum suction tube or fiber bronchoscope can be directly inserted into the inner tube 72 and the intubation sub-tube 6 from the sputum suction connector 10. The sputum suction connector 10 is provided with a sealing plug 101 for sealing the sputum suction connector 10 when not in use.
进气接头74和出气接头73上分别设置进气标识和出气标识，该进气标识或者出气标识可以是文字或者不同颜色，以便于对两者进行区别。An air inlet mark and an air outlet mark are respectively provided on the air inlet connector 74 and the air outlet connector 73. The air inlet mark or the air outlet mark can be text or different colors to facilitate the distinction between the two.
所述进气导管9和出气导管8均可为钢丝螺纹管，便于调整新型气管插管100与呼吸系统插接的角度。The inlet conduit 9 and the outlet conduit 8 can both be steel wire threaded tubes, which facilitates adjustment of the angle at which the novel endotracheal tube 100 is plugged into the respiratory system.
本实施例中的辅助插头7的外套筒71上也设有两个辅助连接耳714，外套筒71套接于导管连接端22时，辅助连接耳714与连接耳221相互间隔设置，用于辅助对接辅助插头7和插管接头2。The outer sleeve 71 of the auxiliary plug 7 in this embodiment is also provided with two auxiliary connecting ears 714. When the outer sleeve 71 is sleeved on the catheter connecting end 22, the auxiliary connecting ears 714 and the connecting ears 221 are arranged at intervals from each other for assisting the docking of the auxiliary plug 7 and the tube connector 2.
实施例2Example 2
如图7至图9所示，本实施例的结构与上述实施例1的结构基本相同，主要区别在于，本实施例的内接管72连接的出气接头73从锥台侧壁7121转移到外套筒71的中空锥台状连接端712的外端部，而由于所述吸痰接头10同轴连接设于连接端712的外端，并且直线连通于内接管72的直线段724，即出气接头73可垂直连接与吸痰接头10连接的直线段724的侧壁，以连通出气导管8和内接管72；而外套筒71连接端712连通的进气接头74位于中空锥台状连接端712的锥台侧壁7121，以直接连通出气导管9和插管1的内部腔室13。同样可以使本实用新型的新型气管插管100具有两个独立腔室。As shown in Fig. 7 to Fig. 9, the structure of this embodiment is basically the same as that of the above-mentioned embodiment 1, and the main difference is that the outlet connector 73 connected to the inner tube 72 of this embodiment is transferred from the cone side wall 7121 to the outer end of the hollow cone-shaped connecting end 712 of the outer sleeve 71, and because the suction connector 10 is coaxially connected to the outer end of the connecting end 712 and is linearly connected to the straight section 724 of the inner tube 72, the outlet connector 73 can be vertically connected to the side wall of the straight section 724 connected to the suction connector 10 to connect the outlet tube 8 and the inner tube 72; and the inlet connector 74 connected to the connecting end 712 of the outer sleeve 71 is located at the cone side wall 7121 of the hollow cone-shaped connecting end 712 to directly connect the outlet tube 9 and the internal chamber 13 of the cannula 1. Similarly, the new tracheal cannula 100 of the utility model can have two independent chambers.
实施例3Example 3
如图10至图12所示，本实施例的结构与上述实施例1的结构基本相同，主要区别在于，本实施例的外套筒71连接端712连通的进气接头74位于中空锥台状连接端712的外端部；而所述内接管72省去直线段724，而折弯段723延伸连接出气接头73，所述出气接头73位于连接端712的锥台侧壁7121，包括同轴于折弯段723的第一端731和设置于第一端731侧壁的第二端732，所述吸痰接头10同轴连通设置于第一端731，所述第二端732则连接出气导管8。As shown in Figures 10 to 12, the structure of this embodiment is basically the same as that of the above-mentioned embodiment 1, with the main difference being that the air inlet connector 74 connected to the connecting end 712 of the outer sleeve 71 of this embodiment is located at the outer end of the hollow conical connecting end 712; the inner pipe 72 omits the straight section 724, and the bent section 723 extends to connect the air outlet connector 73, the air outlet connector 73 is located at the conical side wall 7121 of the connecting end 712, includes a first end 731 coaxial with the bent section 723 and a second end 732 arranged on the side wall of the first end 731, the suction connector 10 is coaxially connected to the first end 731, and the second end 732 is connected to the air outlet duct 8.
由此，吸痰管后或纤维支气管镜可从吸痰接头10沿着折弯段723弯曲进入内接管72和插管子管6。而出气导管8连通出气接头73的第二端732、内接管72和插管子管6，形成独立的腔室。Thus, the suction tube or fiber bronchoscope can be bent from the suction connector 10 along the bending section 723 into the inner tube 72 and the intubation sub-tube 6. The outlet conduit 8 connects the second end 732 of the outlet connector 73, the inner tube 72 and the intubation sub-tube 6 to form an independent chamber.
