Description

一种纤维支气管镜呼吸道末梢洁净装置 技术领域
本发明涉及一种医疗器械，尤其是一种呼吸道清洁用手术器械，具体地说是一种纤维支气管镜呼吸道末梢洁净装置。
背景技术
支气管内窥镜一般用于支气管检查、吸痰、清洁手术中，起到去除痰栓、痰液，清洁患者气道的作用，常见的吸痰操作方式为先冲水，然后进行吸液操作。冲水方式为水流向前方直接灌注。冲水和吸痰共用一个通道。这种传统的纤维支气管镜呼吸道清洁(吸痰)方法存在以下临床痛点：1)对于粘附在支气管粘膜的稠厚或干结的痰液，难以快速清理或吸出，严重影响通气功能，甚至危及病人生命；2)其产品结构和操作性能不足以将呼吸道末梢的炎性分泌物或异物清除；3)传统纤维支气管镜的产品设计，只能采用冲水后再吸引的工作模式，不能快速清理呼吸道，耗费时间长，明显增加操作风险；4)操作时先冲水再进行吸液，其冲水和吸液共用一根管腔易造成吸痰管道污染，容易造成患者窒息等安全隐患。因此，现有产品对粘附痰液、深部末梢支气管痰液清理难以彻底和快速，操作风险大、相对费时费力。因此，临床急需创新设计出一种能够快速有效对呼吸道粘膜进行冲刷清洗和吸痰，并能够通过快速虹吸作用清理呼吸道末梢分泌物的装置。
发明内容

一操作手柄13，该操作手柄13上设有拨轮12、废液出液口和注水口，拨轮12与钢丝相 连，钢丝与主插入管15的远端相连，通过控制主插入管15远端的弯曲变形实现内窥镜镜头4的全角度观察；
一主插入管15，该主插入管15的一端可转动地安装在操作手柄13上，另一端用于插主患者支气管中，该主插入管15的外管5中集成有冲水管2、吸液管1和外管弯曲钢丝，冲水管2和吸液管1分别与操作手柄13上的注水口及废液出液口相连通；外管弯曲钢丝的一端与主插入管15插入端的外管相连，另一端与操作手柄13上的操作按键相连；在主插入管15插人患者支气管内的一端的中心设有吸液孔，该吸液孔与吸液管1相贯通，吸液孔的周围安装有内窥镜镜头4和照明光源3，镜头4的数据线穿过主插入管15和操作手柄13与内镜主机10电气连接，照明光源3通过导线与操作手柄13上的电源电气连接；在主插入管15插人患者支气管内的一端的周围设有喷水孔，喷水孔与冲水管2相连通，喷水孔的轴线与主插入管15轴心线的夹角在0°＜θ＜120°。
所述的主插入管15的头端呈截头圆锥型，冲水管2为侧向喷洗冲刷方式；喷水孔的轴线与主插入管15轴心线的夹角在15°＜θ＜90°。
所述的冲水管2和吸液管1相互独立设置而非一管二用。
所述的冲水管2的冲水模式和吸液管1和吸引模式由控制主机8控制，其工作模式有以下三种:①冲水的同时进行吸引；②控制主机8控制冲水T时间进行冲洗，冲水至一定时间开始进行T 1时间吸引，且T略大于T 1(T>T 1)；③分别先冲洗后吸引和先吸引后冲洗。
所述的冲水管2与吸液管1分别设置，且冲水管2排布在吸液管1的周围，冲水管2的出口端与主插入管15端部周围的喷水孔相贯通。
所述的吸液管1位于冲水管2的中心，且吸液管1的进口与主插入管15端部的吸液孔相贯通，冲水管2与出水口主插入管15端部内置的配水环的进水口相连通，配水环的出水口与主插入管15端部周围的喷水孔相贯通。

本发明的有益效果是：
本发明采用冲吸一体式样，手把握持式控制弯曲装置，冲水、吸液分为不同管腔，经管壁侧向冲洗，水流呈发散状直接向气管粘膜进行冲刷，解决了以往直接向气道内注水，而不 能对粘膜加压冲洗洁净支气管的难题。由于冲水和吸引分别通过独立的通道控制，可以方便灵活采用不同的操作模式，例如同时冲吸、错时冲吸、虹吸冲吸等，达到高效快速清洁呼吸道，并可有效清洁呼吸道末梢的目的。且操作省时省力、无痰液二次污染，能明显缩短操作时间、降低纤维支气管镜呼吸道炎性分泌物清理的操作风险。
通过控制主机8(由：主机、软件组成)控制进行脉冲式、间歇性冲洗，且冲洗方向可调节。解决了持续注水清洗易引起气道窒息的难题，配有内窥镜头可视下选择清洗气道，配有活检孔道并能对痰栓患者进行及时清洁。易于医生操作头部呈截头圆锥型设计更易于清洗腔道细小支气管，水流斜喷并对支气管壁痰液清洗更加彻底
本发明结构简单，安全稳定可靠
本发明还可通过对注水和吸引时间的控制使冲入肺气泡中的水瞬间失压，快速进入吸液管中，从而实现肺泡中粘液的清洁，挽救重症肺炎患者的生命。解决目前无法进行有效的肺气泡粘液清洁的难题。

一主插入管15，该主插入管15是本发明创新的核心所在，它一方面将传统的冲洗和吸氮管路分开设置，另一方面改变冲水方向，将传统的沿管路轴线平行冲水改为成一定角度冲水，确保冲洗水能冲刷到主气管或支气管管壁上，提高清洁效果。主插入管15的一端可转动地安装在操作手柄13上，另一端用于插主患者支气管中，该主插入管15的外管5中集成有冲水管2、吸液管1和外管弯曲钢丝，如图2、6、7所示。冲水管2和吸液管1分别与操作手柄13上的注水口及废液出液口相连通；外管弯曲钢丝(图中未示出)的一端与主插入管15插入端的外管相连，另一端与操作手柄13上的操作按键相连；在主插入管15插人患者支气管内的一端的中心设有吸液孔，该吸液孔与吸液管1相贯通，吸液孔的周围安装有内窥镜镜头4和照明光源3，镜头4的数据线穿过主插入管15和操作手柄13与内镜主机10电气连接，内镜主机10连接有显示器，照明光源3通过导线与操作手柄13上的电源电气连接；在主插入管15插人患者支气管内的一端的周围设有喷水孔，喷水孔与冲水管2相连通，喷水孔的轴线与主插入管15轴心线的夹角在0°＜θ＜120°。具体实施所述的主插入管15的头端最好设计成图2、6所示截头圆锥型，冲水管2采用侧向喷洗冲刷方式；喷水孔的轴线与主插入管15轴心线的夹角在15°＜θ＜90°。具体实施时，所述的冲水管2与吸液管1可采用图6、7所示的分别设置，且冲水管2排布在吸液管1的周围，冲水管2的出口端与主插入管15端部周围的喷水孔相贯通。所述的吸液管1还可位于冲水管2的中 心，且吸液管1的进口与主插入管15端部的吸液孔相贯通，冲水管2与出水口主插入管15端部内置的配水环的进水口相连通，配水环的出水口与主插入管15端部周围的喷水孔相贯通。
所述的操作手柄13上安装有旋转按钮14，主插入管15通过所述的旋转按钮14安装在操作手柄13上，拨动旋转按钮14，主插入管15能作设定角度的往复回转。
手握操作手柄，调节拨轮12带动牵引钢丝连接内窥镜头端朝一个方向弯曲，向相反方向调节拨轮12弯曲部位会带动钢丝向相反方向支气管进行弯曲，达到支气管探视的目的，如图5所示。
工作时，内镜主机10对镜头4收集的图像进行处理。握住内镜操作手柄13，通过控制拨轮12对内镜主插入管15前端进行弯曲调节，达到对支气管5内的探查、诊断和痰液冲洗、吸引。通过控制主机8进行控制痰液吸引和冲洗，按压负压吸引按钮11控制吸液管1达到对痰液的吸引；控制控制主机8进行冲水管2的冲洗，转动旋转按钮14对冲水管2进行旋转达到对内镜头端进行旋转的控制，使冲洗水能冲洗到整个管壁表面。
本发明未涉及部分均与现有技术相同或可采用现有技术加以实现。
