Description
技术领域 technical field
本实用新型涉及医疗器械，具体涉及一种适用于呼吸科使用的气管插管。 The utility model relates to a medical device, in particular to a tracheal intubation tube suitable for use in the Department of Respiratory Medicine.
背景技术 Background technique
气管插管术是一种气管内麻醉和抢救病人的技术，也是保持上呼吸道通畅的最可靠手段。但在手术时，经常会遇到病人下呼吸道分泌物结痂而堵塞气管，需要及时进行吸引操作。由于目前插入使用的气管都是单通道，即呼吸和吸引同采用一条通道，导致较浓的痰液及痰痂附着在气管壁上很难被吸引出来。 Endotracheal intubation is a technique for endotracheal anesthesia and patient rescue, and it is also the most reliable means of keeping the upper airway open. However, during the operation, it is often encountered that the patient's lower respiratory tract secretion scabs and blocks the trachea, and suction operation needs to be performed in time. Since the trachea used for insertion is single-channel at present, that is, the same channel is used for breathing and suction, resulting in thicker sputum and sputum scab attached to the tracheal wall, which is difficult to be sucked out.
发明内容 Contents of the invention
本实用新型所要解决的技术问题是：针对上述问题，提供一种可以有效吸除痰痂的清除器。 The technical problem to be solved by the utility model is: aiming at the above problems, provide a remover that can effectively suck and remove phlegm and scab.
本实用新型的技术解决方案是：它包括导管，导管的前端设有导引头及出气孔，导管的后端设有进气孔，所述导管的外壁于导引头后方设有气囊，导管的外壁于后端设有吸引接头，导管壁内设有吸气通道，吸气通道后端与吸引接头连接，吸气通道前端于气囊前方的壁上设有内吸气孔和外吸气孔分别与导管的内外连通。 The technical solution of the utility model is: it includes a catheter, the front end of the catheter is provided with a guide head and an air outlet, the rear end of the catheter is provided with an air inlet, the outer wall of the catheter is provided with an air bag behind the guide head, and the catheter The outer wall of the tube is provided with a suction joint at the rear end, and an inhalation channel is provided in the catheter wall, the rear end of the inhalation channel is connected with the suction joint, and the front end of the inhalation channel is provided with an inner inhalation hole and an outer inhalation hole on the wall in front of the airbag communicate with the inside and outside of the catheter respectively.
本实用新型的技术效果是：它具有结构简单、使用方便及可有效清除附着在气管壁上的痰液及痰痂的优点。呼吸通道与吸引通道各自分离，互不影响，并且，二者在端部交汇，吸引通道与呼吸通道在交汇处形成回路，刚好有利于清除交汇处的浓痰液及痰痂，使呼吸道保持畅通。 The technical effect of the utility model is: it has the advantages of simple structure, convenient use and effective removal of phlegm and phlegm scab attached to the trachea wall. The respiratory channel and the suction channel are separated from each other and do not affect each other. Moreover, the two meet at the end, and the suction channel and the respiratory channel form a circuit at the intersection, which is just conducive to clearing the thick sputum and sputum scab at the intersection and keeping the airway unobstructed. .
附图说明 Description of drawings
图1为本实用新型的结构示意图。 Fig. 1 is the structural representation of the utility model.
具体实施方式 Detailed ways
如图1所示，它包括导管1，导管1的前端设有导引头2及出气孔3，导管1的后端设有进气孔4，所述导管1的外壁于导引头2后方设有气囊5，导管1的外壁于后端设有吸引接头6，导管1壁内设有吸气通道7，吸气通道7后端与吸引接头6连接，吸气通道7前端于气囊5前方的壁上设有内吸气孔8和外吸气孔9分别与导管的内外连通。 As shown in Figure 1, it comprises a catheter 1, the front end of the catheter 1 is provided with a guide head 2 and an air outlet 3, and the rear end of the catheter 1 is provided with an air inlet 4, and the outer wall of the catheter 1 is behind the guide head 2 An airbag 5 is provided, and the outer wall of the catheter 1 is provided with a suction joint 6 at the rear end, and an inhalation channel 7 is provided in the wall of the catheter 1, and the rear end of the inhalation channel 7 is connected with the suction joint 6, and the front end of the inhalation channel 7 is in front of the air bag 5 The wall of the inner suction hole 8 and the outer suction hole 9 are respectively communicated with the inside and outside of the conduit.
所述内吸气孔8口径小于外吸气孔9，利于外孔产生较大吸力。 The diameter of the inner suction hole 8 is smaller than that of the outer suction hole 9, which is beneficial for the outer hole to generate greater suction.
本实用新型可采用医用橡胶制成。呼吸与吸引的通道分开，各自独立，由于二者在导引头2处交汇，在强力吸气时，可直接与呼吸通道构成回路，在清除痰痂时，不会伤及肺。为增大吸气通道7，可以采用多条通道并行的结构。由于痰液粘稠度较高，在加大吸力的情况下，在交汇处会产生较强吸力，使痰液逐渐被整体吸出。 The utility model can be made of medical rubber. The channels of breathing and suction are separated and independent. Since the two meet at the 2 places of the seeker, they can directly form a circuit with the breathing channel during strong inhalation, and will not hurt the lungs when removing phlegm scabs. In order to enlarge the suction channel 7, a structure in which multiple channels run in parallel can be used. Due to the high viscosity of the sputum, when the suction is increased, a strong suction will be generated at the intersection, so that the sputum is gradually sucked out as a whole.
