Description

一种多功能可视导管 技术领域
本发明涉及医疗器械领域，具体涉及到一种多功能可视导管。
 背景技术
吸痰管是临床医疗上常用的一种医疗器具，其主体为一根软管和一个抽吸装置，由于医护人员无法直接看到痰液在气管中的具***置，医护人员常常需要根据经验来预测，然后采用盲插吸痰管的方式吸痰，这种方式不但非常耗时耗力，而且吸痰不够干净，有时候还会损坏咽喉部、气管内粘膜，给病人带来极大痛苦。  
对于昏迷及咳痰无力的患者，由于其咳嗽吞咽功能下降，造成痰液排出困难。若痰液吸入肺部，容易出现肺部感染，甚至危及生命，针对深部位痰液的排出，目前临床采用吸痰管的解决方法；而对于昏迷及不能吞咽的患者，为了保证其营养需求，维持水、电解质平衡及药物的应用，促进疾病恢复，目前采用胃管输送营养液的解决方法，上述两种解决方案目前在医疗领域得到了大量的应用。
中国专利号201420135609.5公开了一种可视吸痰管，其包括用于拍摄寻找痰液和异物位置的拍摄腔和用于排出痰液和异物的吸引腔，所述拍摄腔的端部设置有用于拍摄寻找痰液和异物位置的图像拍摄模块，所述图像拍摄模块将图像数据传输给数据接口，进而传输至外部控制和显示设备。但上述解决方案虽然解决了可视化问题，该可视吸痰管作为一次性医用器材，使用后将被丢弃，丢弃部分包含了图像拍摄模块、数据传输线以及数据接口等，大大增加了吸痰的成本，从而增加了患者的经济负担。
因此，有必要开发一种多功能可视导管，既可以作为吸痰管，也可以作为胃管，减轻患者负担，减少环境污染。
 技术问题
本发明的目的在于开发一种多功能可视导管，既可以作为吸痰管，也可以作为胃管，减轻患者负担，减少环境污染。
 技术解决方案
本发明提供一种多功能可视导管，具体涉及一种用于清理口腔、咽喉部、气管内痰液等异物，用于帮助不能吞咽的患者输送必要水分和营养的可视导管。
本发明的技术方案如下：
一种多功能可视导管，包括拍摄腔道，辅助腔道及光源腔道，拍摄腔道、辅助腔道及光纤腔道的排列方式采用并排或堆叠的方式设置，其中：
拍摄腔道，用于容置可插拔的摄像模块，所述摄像模块通过透明罩和软管与外界隔离，拍摄体内部位的图像，拍摄腔道的前端通过透明罩密封，拍摄腔道的后端设置可插拔接口；
辅助腔道，用于吸出或注入流体物质；
光源腔道，用于容置光源模块，提供摄像模块所需的照明光源。
进一步的，所述摄像模块的前端还可以包括可旋转部件，进而带动多功能可视导管前端旋转，方便导管对不同方向进行观察或移动。
进一步的，所述的可视导管还包括设置在前端的透明罩，透明罩的前端表面可以为平面或球面。
进一步的，所述的透明罩采用PMMA或PC材料制成。
进一步的，所述的可视导管前端圆周表面还布设有开孔，开孔的数量为1个或多个。
进一步的，所述开孔的形状可以为圆形、方形或不规则形状的任一种。
进一步的，所述的可视导管采用硅胶、聚氯乙烯、聚乙烯、聚氨脂制成。
进一步的，所述辅助腔道的截面形状可以为圆形、月牙形、异形的任一种。
进一步的，所述的辅助腔道的数量可以是一个或多个。
进一步的，所述的光源腔道可以采用凹槽或密封结构。
进一步的，所述的拍摄腔道和辅助腔道可以采用套设的方式排布。
 有益效果
采用本发明的多功能可视导管，既可以作为吸痰管，也可以作为胃管，成本低廉，操作方便，减轻患者负担，减少环境污染。

 本发明的最佳实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
    请参考图1本发明的可视导管结构示意图，该可视导管由可视导管前端1， 开孔2，光纤凹槽3，导管管体4，导管三分接头5，辅助腔道延长管6，辅助腔道接头7，拍摄腔道接头8，光纤9及光纤光源接头10组成，其中开孔2布设在导管管体4前端部位的圆周面，用于吸取痰液或注射营养液等流体物质，其开设数量与形状不限，例如可以是圆形、方形或不规则形状。可视导管由拍摄腔道101、辅助腔道102及光纤腔道组成，管腔均为软管，可视导管采用硅胶、聚氯乙烯、聚乙烯、聚氨脂制成。
    进一步参考图2可视导管前端的横截面示意图及图3可视导管的透明罩结构示意图，其组成结构包括：
    拍摄腔道101，该腔道前端端口处安装有一透明罩103，透明罩103既可以保证摄像镜头观察和拍摄的光学要求，又起到密封拍摄腔道101的目的，避免了摄像镜头模块与体液接触而带来的交叉污染的风险，从而在不需要消毒清洗拍摄镜头线缆的情况下实现多次反复使用的目的，拍摄腔道101用于容置可插拔的摄像模块，并通过透明罩103和软管与外界隔离，拍摄体内部位的图像。本领域技术人员可以理解的是，摄像模块的前端进一步还可以包括可旋转部件（图中未示出），进而带动多功能可视导管前端旋转，方便导管对不同方向进行观察或移动，该可旋转部件例如可以是微型轴承或类似功能的部件。拍摄腔道101的后端设置可插拔接口，拍摄腔道101的前端通过透明罩103密封，透明罩103采用PMMA或PC材料制成，透明罩103的前端表面可以为平面或球面等结构。
    辅助腔道102，用于吸出痰液或胃液等体液，或注入食物、水和药物，其腔道前端侧面有一个或多个开孔，其末端的辅助腔道接头7可以连接负压装置进行吸痰，也可通过注射器注射水或药物物质，接头处设有塞盖。可以理解的是，辅助腔道102的截面形状还可以采用圆形、月牙形、异形等其它适宜的形状，且辅助腔道102的个数可以是一个或多个。
    光源腔道，光源腔道主要由光纤凹槽3组成，便于将光纤9嵌入在凹槽中，使其不易滑出，用于容置光纤9，该光纤为摄像镜头提供光源。可以理解的是，光源腔道也可以采用圆形密封结构，光纤9通过圆形密封结构穿入到可视导管前端部位。在实际使用前，将导管尾部的光纤光源接头10与外部的光源连接，即可为导管前端的摄像镜头正常观察提供光源。
    本领域技术人员可以理解的是，拍摄腔道101、辅助腔道102及光纤腔道的排布方式不限于图2所示的排列方式，例如，拍摄腔道101和辅助腔道102还可以采用套设的方式排布，进一步的，拍摄腔道101、辅助腔道102及光纤腔道的排列方式还可以是三根腔道并排或堆叠的方式设置。
    可视导管的工作过程如下：
     使用前，将可视导管前端1的带有***镜头的可视线缆通过拍摄腔道101末端的接头处穿入到拍摄腔道101中，直至到达可视导管的透明罩103处，此时摄像镜头的前端镜头刚好到达腔道的前端端口。
    当进行吸痰操作时，将导管的辅助腔道接头7连接负压装置，并将导管***到患者的咽喉部或气管内，在***过程中，在外部的可视装置（图中未示出）显示屏幕上观察导管前端摄像头拍摄的导管***的画面，根据观察到的情况调整导管***的位置或深度，进而吸出痰液。
    当进行胃管操作时，将导管从患者的鼻腔或口腔***，***过程中，边观察拍摄的画面，边***边调整，直至可视导管到达胃部合适位置后，通过注射器将营养物质、水或药物等液体通过辅助腔道接头7注射到辅助腔道102内，通过腔道流入到胃部，在此过程中仍然可以通过拍摄到的画面,观察液体注入胃部的情况。
    当观察结束后，将导管中的摄像头线缆抽出，由于摄像头没有污染，无须进行消毒处理，减少了医务人员的工作量和消除成本，下次使用时，仅需要将可视装置***新的导管即可，可视导管作为一次性医疗耗材，既实现了可视化操作，且成本低廉。
    本发明的多功能可视导管，既可以作为可视吸痰管，也可以作为可视胃管，当作为可视吸痰管时，用于清理口腔、咽喉部及气管内的痰液和异物；当作为可视胃管时，用于向患者的胃部注入营养物质、水和药物等物质。
    以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
