技术领域
本申请涉及医疗器械技术领域，具体涉及一种一次性冲洗吸引引流管及其使用方法。

实施例1
如图1-5所示的一种一次性冲洗吸引引流管包括冲洗管1、吸引管2和安装座3，所述安装座3的一端分别安装有所述冲洗管1和所述吸引管2，另一端安装有气接头4和水接头5；吸引管2由软质不锈钢管制作而成，医生可根据手术需要，用手任意弯曲成所需角度及状态，同时其前端部做圆钝化处理，以免给患者造成伤害，冲洗管1由硅胶、PVC或不锈钢材质做成，与吸引管2并排放置，冲洗管1的前端为斜口式，其距离所述吸引管2前端距离为5-35mm；所述冲洗管1外还连接有套管18，所述套管18套设在所述吸引管2外。
所述安装座3包括管体座31和控制座32，所述管体座31的一端安装有所述冲洗管1和所述吸引管2，另一端与所述控制座32可拆卸地连接；管体座31有若干种规格，配不同尺寸规格的吸引管2以备手术使用，控制座32为操作者手持部位，也是功能性部件。
所述控制座32包括控制座本体321、通水内管322、锁水销轴323、水控制开关324和固定壳325，所述固定壳325可拆卸地安装所述控制座本体321上，所述固定壳325上设置有多个安装插件20，控制座本体321上设置有多个与所述安装插件20相配合的安装定位孔19，所述固定壳325与所述控制座本体321之间形成有安装槽，所述水控制开关324安装在所述安装槽内，其可沿安装槽前后滑动，所述锁水销轴323可活动地安装所述控制座本体321内，所述通水内管322安装在所述控制座本体321内，所述锁水销轴323与所述水控制开关324配合使用以控制所述通水内管322的通水量，通过锁水销轴323的上下移动，对通水内管322进行挤压或者松开，实现通水内管322的通与堵以及通水量大小的调控。
所以控制座本体321上开设有负压调节口6。通过负压调节口6可以对吸引管2的吸力进行控制，实现吸引的效果，进一步地，负压调节口6设计成与人的拇指形状相匹配的弧形，方便人的操作。负压调节口6的位置靠近水控制开关324，方便一只手的操作。
所述管体座31的内部分别设置有通水内腔311和第一通气内腔312，所述管体座31背离所述冲洗管1的一端分别连接有水路连接座7和气路连接座8。通过水路连接座7和气路连接座8能够实现管体座31与控制座32的插接，同时保证水路和气路的各自畅通。
所述气路连接座8内开设有与所述第一通气内腔312连通的第二通气内腔80；所述气路连接座8外设置有两个对称设置的连接导轨9和一个环状的限位凸起10；所述气路连接座8上开设有与所述负压调节口6位置相对应的缺口81。所述控制座本体321内设置有与所述第二通气内腔80连通的负压通道11，所述负压通道11的一端内部开设有与所述连接导轨9相配合的定位槽110和与所述限位凸起10相配合的凹槽，另一端安装所述气接头4。通过连接导轨9与定位槽110、限位凸起10与凹槽的配合，完美实现管体座31与控制座32的插接，同时也能防止管体座31与控制座32之间发生旋转。
所述控制座本体321内还开设有内管槽12，所述通水内管322安装在所述内管槽12内；所述通水内管322的一端安装在所述水路连接座7上，另一端连接所述水接头5。如图6所示，所述通水内管322包括管体3221和安装头3222，其中安装头3222卡接在所述内管槽12的定位孔内，安装头3222远离管体一端的内腔孔径与所述水路连接座7外径相匹配，以防止水的渗出。
所述内管槽12的两侧分别设置有均纵向开口的第一导槽13和第二导槽14，所述锁水销轴323的一端安装在所述第一导槽13内，另一端安装在所述第二导槽14内。本实施例的第一导槽13和第二导槽14均为内径大小一致的结构，能控制锁水销轴323的上下移动，本申请的第一导槽13和第二导槽14的形状不仅限于本实施例的结构，也可以设计成内径大小从下至上逐渐变大的斜槽。
所述水控制开关324包括操作板3241、安装滑块3242和销轴控制块3243，所述操作板3241、所述安装滑块3242和所述销轴控制块3243从上之下依次连接，安装滑块3242安装在所述固定壳325与所述控制座本 体321之间形成的安装槽内，且能沿安装槽两端来回滑动；所述销轴控制块3243为倒置的直角梯形块，其包括斜腰面15和下底面16，所述销轴控制块3243下方开设有豁口17。操作板3241设计成波浪形，能增加手与操作板3241之间的摩擦力，防止操作过程中打滑，减少失误。豁口17能通过通水内管322，为通水内管322让位，斜腰面15为功能性导向坡，用于控制锁水销轴323的上下移动距离，进而达到控制水流量的目的。水控制开关324与锁水销轴323配合使用调节水流的大小的原理为：水控制开关324推至两端分别为开端和关端，如图7和8所示，冲洗时，销轴控制块3243的斜腰面15抵住锁水销轴323使其上下移动实现通水内管322内水通量的大小，关闭冲洗时销轴控制块3243的下底面16抵住锁水销轴323，将锁水销轴323移动至最底部，将通水内管322压扁关闭，阻断通水，当将水控制开关324在开端和关端两个极限内移动时，可将水流调节到所需水流大小。

所述发光二极管211的正负引脚，与所述电池212的正负极对应连接；所述发光二极管211的其中一个引脚上安装有弹性引脚23，所述弹性引脚23与所述电池212间被绝缘片24隔绝，当使用时，抽出所述绝缘片24，使所述弹性引脚23接触到电池212的正负极上，从而电池212 电力驱动发光二极管211发光。
