Description
技术领域technical field
本发明涉及医疗器械，尤其是涉及一种新型气管导管。The invention relates to a medical device, in particular to a novel trachea tube.
背景技术Background technique
气管插管术是指将特制的气管导管，通过口腔或鼻腔插入病人气管内；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。在出现如下情况时需要进行气管插管术:1 . 在全身麻醉时，呼吸道难以保证通畅的患者者，如颅内手术、开胸手术、需俯卧位或坐位等特殊体位的全麻手术；颈部肿瘤压迫气管，颌，面，颈，五官等全麻大手术，极度肥胖病人；全麻药对呼吸有明显抑制或应用肌松药患者，都应进行气管插管术。2. 危重病人抢救时，气管插管术发挥了重要作用；呼吸衰竭需要进行机械通气者，心肺复苏，药物中毒以及新生儿严重窒息时，都必须行气管插管术。3.某些特殊麻醉：如并用降温术，降压术及静脉普鲁卡因复合麻醉等均需在病人现有气管进行插管。Endotracheal intubation refers to inserting a special endotracheal tube into the patient's trachea through the oral or nasal cavity; it is a technique for endotracheal anesthesia and patient rescue, and it is also the most reliable means of keeping the upper airway open. Tracheal intubation is required when the following situations occur: 1. Patients whose airway is difficult to ensure unobstructed during general anesthesia, such as intracranial surgery, thoracotomy, general anesthesia surgery requiring special positions such as prone position or sitting position; Patients with major operations under general anesthesia such as internal tumors compressing the trachea, jaw, face, neck, and facial features, and extremely obese patients; patients with obvious inhibition of breathing by general anesthesia or who are treated with muscle relaxants should all undergo tracheal intubation. 2. Tracheal intubation plays an important role in the rescue of critically ill patients; respiratory failure requiring mechanical ventilation, cardiopulmonary resuscitation, drug poisoning, and severe neonatal asphyxia must all undergo tracheal intubation. 3. Some special anesthesia: if combined with hypothermia, antihypertensive surgery and intravenous procaine combined anesthesia, etc., it is necessary to intubate the patient's existing trachea.
如图1所示，现有气管导管一般为由间隙套装的透明硬质内套管和外套管构成的导管本体以及设置于导管本体上的扩张气囊，内套管为通管，外套管两端密封形成中部的密封空腔，外套管后端设置有充气导管，用于给扩张气囊充气；外套管上带有刻度标识，可判断插入深度。操作时，借助喉镜和导丝将气管导管插入喉部，插入深度一般为插入端距门齿18-22cm,插入后通过充气导管向扩张气囊内注入气体，扩张气囊扩开起固定作用，固定后将呼吸机与气管导管后端相连，最后在病人口部放置一中空硬管，防止病人牙齿咬断或咬闭气管导管。As shown in Figure 1, the existing tracheal catheter is generally a catheter body composed of a transparent hard inner sleeve and an outer sleeve set in a gap and an expansion balloon arranged on the catheter body. The inner sleeve is a through tube, and the two ends of the outer sleeve are Sealing forms a sealed cavity in the middle, and an inflation catheter is provided at the rear end of the outer sleeve for inflating the expansion balloon; the outer sleeve is provided with a scale mark for judging the insertion depth. During operation, insert the endotracheal tube into the throat with the help of a laryngoscope and a guide wire. The insertion depth is generally 18-22 cm from the insertion end to the incisors. After insertion, inject gas into the dilation balloon through the inflation catheter. Connect the ventilator to the back end of the endotracheal tube, and finally place a hollow hard tube in the patient's mouth to prevent the patient from biting off or biting off the endotracheal tube.
现有的扩张气囊无法完全覆盖气管导管前端，人体气管内的液体（如痰液）会长期积存在扩张气囊前部的气管导管和人体气管壁之间；并且现有气管导管在进行吸痰时只能吸引气管导管内部的液体，所以在扩张气囊后部的气管导管和人体气管壁之间也会积存大量液体；液体的长期积存影响病人呼吸，造成呛咳，极易导致细菌感染；现有的气管导管也无法对扩张气囊后部的人体气管壁进行冲洗或局部应用药物。另外，由于该中空硬管与气管导管不是一体结构，并且是在气管导管插管完成后放置，因此放置时需要再次将病人口部掰开，操作麻烦；同时中空硬管下方没有放脱落结构，极易滑入病人口中对其造成损伤，且中空硬管上没有弹性层，病人牙齿咬紧后可能对病人牙齿造成损伤。The existing dilation balloon cannot completely cover the front end of the endotracheal tube, and the liquid (such as sputum) in the human trachea will accumulate between the endotracheal tube at the front of the dilation balloon and the human trachea wall for a long time; It can only absorb the liquid inside the endotracheal tube, so a large amount of liquid will accumulate between the endotracheal tube at the back of the dilated balloon and the human body's trachea wall; the long-term accumulation of liquid will affect the patient's breathing, cause choking, and easily lead to bacterial infection; The traditional endotracheal tube cannot flush or locally apply drugs to the human body's tracheal wall at the rear of the dilation balloon. In addition, since the hollow hard tube and the endotracheal tube are not integral structures, and are placed after the endotracheal tube is intubated, the patient’s mouth needs to be opened again when placing it, which is troublesome to operate; at the same time, there is no fall-off structure under the hollow hard tube, It is very easy to slip into the patient's mouth and cause damage to it, and there is no elastic layer on the hollow hard tube, which may cause damage to the patient's teeth after the patient's teeth are clenched.
