Description

电子喉镜 技术领域
本发明涉及一种电子喉镜，特别是一种具有吸痰装置的电子喉镜。
背景技术
电子喉镜一般由摄像头、中空硬质管(或称“连接杆”)、手柄和控制显示模块组成；中空硬质管的前端设有摄像头，其后端与手柄固定连接，其内部可以通导线；手柄的后部连接有控制显示模块。在使用电子喉镜的诊疗过程中，电子喉镜一般配套气管软管(或称“气管插管”，或“气管导管”，或“插入管”)使用，即将电子喉镜的中空硬质管插入气管软管中，气管软管周向包覆着带有摄像头的中空硬质管深入患者喉腔内。
在诊疗过程中，患者喉腔内的痰液会完全覆盖住电子喉镜的摄像头，影响医生的检查效果，因此需要将痰液及时清除。然而，使用电子喉镜并同时对患者，特别是对昏迷患者的吸痰或喉腔护理一直是医护工作中的难点，因为应用常规辅助器械的吸痰方法往往不能达到彻底清除痰液和口腔污垢的目的，同时，由于所用辅助器械繁杂，操作也不方便。
中国实用新型专利CN203388832(一种软管喉镜)公开了一种改进的吸痰方案，为了将痰液吸出，该实用新型在气管软管的管壁内埋设吸痰导管，吸痰导管沿着气管软管的轴向延伸，其后端设有吸痰器接口，其前端有一个小口(即“吸痰口”)设置于气管软管的前端部分的内壁上，痰液即通过吸痰导管从吸痰口吸出。
中国实用新型专利CN201168310(一种多功能发光气管导管)也公开了一种吸痰方案，与实用新型CN203388832的改进相同，同样是在气管软管的管壁内埋设吸痰导管，吸痰口同样是一小口，设于气管软管的前端部分的内壁上。
上述两个实用新型均将吸痰导管设在气管软管的管壁内，它们的缺陷在于吸痰口距离摄像头的位置是无法确定的，通常情况下，吸痰口会位于距离摄像头较远的位置，这是因为气管软管的规格较多，尺寸也都不一样。根据《中华人民共和国医药行业标准YY0337.1-2002》对气管软管的规定可知，气管软管因其内径以及内径相匹配的长度不同，共有十九种规格，所以设于气管软管壁上的吸痰口较难匹配或对应中空硬质管上的摄像头的位置，从而无法有效吸除或清理摄像头周边的痰液或污垢。
因此，就目前电子喉镜相关吸痰方案的现有技术而言，由于吸痰口均远离或不能稳定 设于摄像头周边，同时吸痰器的功率一般较小(吸痰力较大会造成患者不适，或致其喉腔壁损伤)，因而不能有效地完全吸除覆盖于摄像头周边的痰液或污垢；即使吸痰口恰好处于摄像头的周边，由于只是在摄像头周边一侧的某一点进行吸痰，依然不能有效去除摄像头周边的痰液。
发明内容
