Abstract

本发明涉及一种无针正压接头，该正压接头主要与输注器具配合使用。本正压接头使用时随正压接头胶塞的开启，从而实现单向的液体流动，以避免由于针头穿刺可能带来的切削的污染，当输注器具拔下时，该正压接头会产生一个正压，自动使正压接头内的液体向前推进，避免血液的回流，从而防止留置针的堵塞。本发明结构简单，不增加部件，效果明显。

Description

无针正压接头
技术领域
本发明涉及一种医疗用品，具体为无针正压接头。
背景技术
留置针是长期留置于人体血液循环系统的器械，能进行多次给药，避免重复穿刺，减少病人痛苦。但是，每次输注完毕后，如果直接从留置器械上拔除针管或接头，将形成负压并引起血液回流进入留置器械，形成血栓堵塞，造成下次无法继续输液。
发明内容
针对上述问题，本发明的目的在于提供一种无针正压接头，包括外壳、胶塞、底座，其特征在于：所述外壳内侧面有均匀分布的引流槽，所述胶塞包括实芯的上端部和中空的下端部，该胶塞为一体成型，所述胶塞下端部为一圆形薄片，中部为一圆柱体与上端部连接，所述的底座为一鲁尔接头，其内腔与外壳的引流槽相通。
所述的无针正压接头，其特征在于：所述胶塞由硅橡胶制成。
所述的正压接头主要与输注器具配合使用。本正压接头使用时随正压接头胶塞的开启，从而实现单向的液体流动，以避免由于针头穿刺可能带来的切削的污染，当输注器具拔下时，该正压接头会产生一个正压，自动使正压接头内的液体向前推进，避免血液的回流，从而防止留置针的堵塞。
相比现有技术，本发明具有如下优点：
1、当输注器具拔下时，产生一个正压，自动使正压接头内的液体向前推进，避免血液的回流，从而防止留置针的堵塞。
2、产品结构设计简单，为工业上常用的结构，不增加生产难度。
附图说明
图1为无针正压接头整体示意图；
图2为无针正压接头输注状态示意图；
具体实施方式
下面结合附图对本发明作进一步的描述。
如图1所示，无针正压接头包括外壳1、胶塞2、胶塞上端部21、胶塞中部22、胶塞下端部23、和底座3。
如图2所示，输注时插入锥头4，胶塞上端部21被力向下压，胶塞中部22由于压力的作用而弯曲。
当完成输注时，拔除锥头4，胶塞中部22回弹，带动胶塞上端部21前移，从而产生压力使正压接头内的液体向前推进，避免血液的回流。
本技术领域中的普通技术人员应该认识到，以上的实施例只是用来说明本发明，而非作为对本发明的限定，只要在本发明的实质设计范围内，对以上实施例的变化或变型都将落在本发明的权利要求范围内。

Claims (2)

1.一种无针正压接头，包括外壳、胶塞、底座，其特征在于：所述外壳内侧面有均匀分布的引流槽，所述胶塞包括实芯的上端部和中空的下端部，该胶塞为一体成型，所述胶塞下端部为一圆形薄片，中间为一圆柱体与上端部连接，所述的底座为一鲁尔接头，其内腔与外壳的引流槽相通。
2.如权利要求书1所述的无针正压接头，其特征在于：所述胶塞由硅橡胶制成。
