一次性硅塑喉罩  Disposable silicone plastic laryngeal mask
技术领域 Technical field
本发明属于医疗器械技术领域， 特别是涉及一种在手术麻醉或危重患者抢救时应用的造 价低廉、 操作简便且密封严紧可靠的一次性硅塑喉罩。  The invention belongs to the technical field of medical instruments, and particularly relates to a disposable silicone plastic laryngeal mask which is low in cost, simple in operation and tightly sealed and reliable in application in surgical anesthesia or rescue of critically ill patients.
背景技术 . Background technique .
目前临床上抢救心跳呼吸骤停以及需要接受全身麻醉的患者， 为维持其呼吸而建立有效 的人工气道常采用喉罩来代替气管内插管或呼吸面罩等器材。 目前喉罩产品多为硅橡胶材质 制作， 其气囊柔弹性、 贴附性好， 利于在患者喉咽部形成密封， 但由于造价偏高， 不利于喉 罩在我国的普及， 而且容易发生临床上交互感染的危险。 近年来有 PVC材料制作的一次性 喉罩问世， 此种材质喉罩价格低， 利于普及推广， 尤其通气导管采用螺旋加强衬结构， 在使 用中可任意方向弯曲打折而不会影响通气量， 从而拓宽产品的应用范围， 为医护人员操作提 供了极大便利。 但是 PVC材料制作的一次性喉罩其不足之处在于气囊的弹性欠佳， 因此导 致贴附性和密封性不如硅橡胶喉罩。  Currently, patients who have clinically rescued cardiac arrest and general anesthesia, and establish an effective artificial airway to maintain their breathing often use a laryngeal mask instead of an endotracheal tube or a respiratory mask. At present, most of the laryngeal mask products are made of silicone rubber. The airbags are soft and elastic, and have good adhesion. It is good for sealing in the throat and throat of patients. However, due to the high cost, it is not conducive to the popularity of laryngeal masks in China, and it is prone to clinical development. The risk of cross-infection. In recent years, disposable laryngeal masks made of PVC materials have been introduced. The price of such laryngeal masks is low, which is conducive to popularization. In particular, the ventilation ducts adopt a spiral reinforcing lining structure, which can be flexed and bent in any direction without affecting the ventilation volume. Broaden the application range of the product and provide great convenience for the operation of medical personnel. However, the disadvantage of the disposable laryngeal mask made of PVC material is that the elasticity of the airbag is not good, so that the adhesion and sealing are not as good as the silicone rubber laryngeal mask.
