一种气道手术专用三头多功能喉罩A three-head multifunctional laryngeal mask for airway surgery

技术领域technical field

本发明涉及医用喉罩技术领域，具体为一种气道手术专用三头多功能喉罩。The invention relates to the technical field of medical laryngeal masks, in particular to a three-head multifunctional laryngeal mask specially used for airway surgery.

背景技术Background technique

喉罩是英国Brain医生在成人咽喉解剖结构基础上研制而成的，第一、二代喉罩具有许多优点：(1)使用简单，可迅速建立人工气道；(2)放置成功率高，未经训练的医护人员的成功率为87％，总成功率99.81％；(3)通气可靠；(4)避免咽喉及气管粘膜损伤；(5)刺激小，心血管反应小；(6)可用于急救。但是传统的一二代喉罩与呼吸道密封不完全，口腔分泌物增加，易移位，无法有效隔离呼吸道和消化道，可引起胃胀气，严重时并发返流或误吸，限制了其在临床麻醉中的应用。近年来随着材料和技术的进步，出现了多种改进型的第三代喉罩，第三代喉罩继承了一二代喉罩的许多优点，同时更具有自己的特点，主要有：(1)主管呈90度弯曲，有通气管和引流管的设计，引流管可插入胃管引流胃液，防止胃胀气和返流误吸；(2)双气囊设计，通气罩与咽喉部解剖更匹配，密封性更好；(3)喉罩远端位于食管开口，固定好，不易移位。临床研究表明，临床手术中使用第三代喉罩具有操作简单、置管成功率高、血流动力学稳定、诱导期用药少、和发生并发症少的优点，有效性和安全性大大提高，易于在临床麻醉中推广应用。The laryngeal mask is developed by British doctor Brain on the basis of the anatomy of the adult throat. The first and second generation laryngeal masks have many advantages: (1) It is easy to use and can quickly establish an artificial airway; (2) The success rate of placement is high, The success rate of untrained medical staff is 87%, and the overall success rate is 99.81%; (3) ventilation is reliable; (4) throat and tracheal mucosal damage is avoided; (5) stimulation is small, and cardiovascular reaction is small; (6) available for first aid. However, the traditional first- and second-generation laryngeal masks are not completely sealed with the respiratory tract, the oral secretions increase and are easily displaced, and cannot effectively isolate the respiratory tract and digestive tract, which can cause flatulence, and in severe cases, regurgitation or aspiration, which limits its clinical application. application in anesthesia. In recent years, with the advancement of materials and technology, a variety of improved third-generation laryngeal masks have appeared. The third-generation laryngeal masks inherit many advantages of the first- and second-generation laryngeal masks, and at the same time have their own characteristics, mainly including: ( 1) The main tube is bent at 90 degrees, with a ventilation tube and a drainage tube design. The drainage tube can be inserted into the gastric tube to drain gastric juice to prevent gastric flatulence and reflux and aspiration; (2) Double airbag design, the ventilation mask is more suitable for the anatomy of the throat , the sealing performance is better; (3) the distal end of the laryngeal mask is located at the opening of the esophagus, which is well fixed and not easily displaced. Clinical studies have shown that the use of the third-generation laryngeal mask in clinical operations has the advantages of simple operation, high success rate of catheter placement, stable hemodynamics, less medication during the induction period, and fewer complications, and the effectiveness and safety are greatly improved. It is easy to popularize and apply in clinical anesthesia.

如专利号CN103596613A提供一种能够以简单的操作来正确确保气道的喉罩，该喉罩包括：外侧管(4a)及连接器(5)，具有形成有能够连接人工呼吸器的第一连接部(5b)的基端部以及形成有通气开口部的远端部，而且形成有连通第一连接部(5b)与通气开口部的连通路；环状套(7)，基于在该环状套插入到规定的插入位置的状态下膨胀而能够紧贴于患者的气管开口部；舌骨抵接部(6d)、(6e)，从外侧管(4a)向侧方突出，以在环状套(7)插入到插入位置的状态下，在患者的咽头部(T)内从上方抵接于与该患者的舌骨(J7)相当的部位；虽然该喉罩的发明可以保护气道不受伤害，但功能任然不够丰富，在实际操作中由于插入的位置或操作手法的不当容易造成后期喉罩漏气，固定的位置容易因为误碰而造成移位，同时在插入的时候由于手法不当，患者咽喉处结构大小不一等原因容易造成喉罩发生弯折，从而需要拔出，进行反复的插入可能会对患者的咽喉造成损伤。For example, Patent No. CN103596613A provides a laryngeal mask capable of correctly securing the airway with a simple operation, the laryngeal mask comprises: an outer tube (4a) and a connector (5), which has a first connection formed with an artificial respirator capable of being connected The base end part of the part (5b) and the distal end part formed with the ventilation opening part are formed with a communication path connecting the first connection part (5b) and the ventilation opening part; the annular sleeve (7) is based on the annular The sleeve is inflated to be in close contact with the trachea opening of the patient in a state where the sleeve is inserted into the predetermined insertion position; In the state where the sleeve (7) is inserted into the insertion position, it is in contact with the patient's hyoid bone (J7) from above in the patient's pharyngeal head (T); although the invention of the laryngeal mask can protect the airway It is not damaged, but the function is still not rich enough. In actual operation, due to the improper insertion position or operation method, it is easy to cause air leakage of the laryngeal mask in the later stage, and the fixed position is easily displaced due to accidental touch. Improper manipulation, different structures in the throat of the patient, etc., can easily cause the laryngeal mask to bend, so that it needs to be pulled out. Repeated insertion may cause damage to the throat of the patient.
