Description

安全注射针保护套
技术领域
本实用新型涉及一种医疗器械，特别涉及一种安全注射针。
背景技术
传统的注射针是由针管、针座、连接部及护套构成的，针管与针座通过连接部粘接而固定，另外针座具有套置固定在针座的外壁上的护套，在注射针使用前可以保护注射针的针管，且可防止针管意外伤人；当在使用时，要将注射针通过针座的内孔套置固定在注射器的锥头上，然后拔下护套，并大都数人都会随手丢弃护套，接着进行抽取药剂与注射药剂的动作，在注射使用完毕后，大都数人都会随手丢弃或少部分人套回护套，无法提供良好的使用安全设施，在套回针盖或清理废弃物时，常会受到针扎的伤害，让使用者产生心理负担，也让医疗废弃物的处理者大伤脑筋，为了克服解决这些问题，本申请人于2009年12月30日申请的、申请号为200920215511.X名称为《安全注射针保护套》中公开了一种注射针安全保护套，该注射针安全保护套包括护套基座、护套，所述护套基座上设有与注射针相适配的套孔，所述护套的下端一侧边与护套基座可转动联接配合，且该护套内设置有针管容置腔，该护套相对针管容置腔的下端开口设置，所述护套内靠近容置腔的侧壁上铰接有转动锁柄，该转动锁柄的内端为勾板，该勾板包括有背板以及连接于背板下端的倒勾板，所述护套容置腔相对背板一侧的侧壁上设置与背板卡配的前后两个锁定凸块，所述的转动锁柄的外端为长柄状的翻转受力杆，所述的护套相对容置腔的顶壁上设有与翻转受力杆适配的通孔，且所述翻转受力杆外端穿过通孔、并在护套基座与护套相对翻转的行程中抵接受力于护套基座。该注射针安全保护套虽然在注射针使用后能对注射针针尖进行屏蔽、防止对医护人员以及其他人员带来伤害感染，但还是存在有一些不足：1、注射针仅靠倒勾板勾住针管，可靠性不高；2、设有一个与护套分体设置的转动锁柄，转动锁柄通过一个销轴连接在护套上，生产及组装非常不便；3、还设有护套基座，结构较为复杂，材料消耗增加，成本上升。
发明内容
本实用新型的目的是为了克服现有技术存在的缺点和不足，而提供一种成本较低、易于生产、更加安全可靠的安全注射针。
为了达到上述目的，本实用新型公开了一种安全注射针，包括由针座及针管构成的注射针和护套，所述针管容置腔中设有倒勾板，其特征在于：所述护套的下端一侧边与针座可转动联接，所述护套内设置有注射针容置腔，所述倒勾板设置在注射针容置腔中并与护套成一体，所述注射针容置腔侧壁与针座之间设有相互卡扣机构。
 与现有技术相比较，本安全注射针的护套与针座直接连接，省却了护套座，倒勾板与护套一体设置，结构更加简单，易于生产；同时注射针容置腔侧壁与针座之间还设有相互卡扣机构，护套与注射针之间通过多点卡接，因此更加安全可靠。
下面结合说明书附图和具体实施方式对本实用新型做进一步介绍。

具体实施方式
如图1-2所示，安全注射针包括由针座101及针管102构成的注射针1和护套2，所述护套2长度与注射针1整体长度相配，与现有类似，护套2一侧开口，截面呈U字形，内腔构成注射针容置腔201，所述注射针容置腔201的长度及宽度要足以容纳针座101及针管102，所述护套2的下端一侧边可转动联接在针座101的外壁上，注射针容置腔201的开口侧朝向针管102方向，使得转动至针管102处时针座101及针管102正好处于注射针容置腔201中，连接方式可以利用塑料的特点采用一体式注塑连接，注射针容置腔201中一体垂直设有倒勾板202，倒勾板202的根部固定在注射针容置腔201的底壁上，所述注射针容置腔201侧壁与针座101之间设有相互卡扣机构。具体卡扣机构包括设置在针座101与注射针容置腔201侧壁相对的侧面上的卡块103及注射针容置腔201相应侧壁上的卡钩203，如图4、6所示，为了更加可靠，优选在所述注射针容置腔201开口两侧的侧壁上对称均各设有一个卡钩203，所述针座101上对应位置也均设有卡块103。所述卡块103大体为条状突起，沿轴向设置，对称设置在护套2与针座101连接点的两侧，所述卡块103背向护套2的面上还设有一条突起的锁条1031，所述注射针容置腔201开口两侧的侧壁上的卡钩203为两个相对突起的凸块，凸块朝向开口的一面成斜面设置，背向开口一面上设有与锁条1031相配的凹槽2031，两条凹槽2031之间的距离与两条锁条1031之间的距离相同。
如图3-7所示，注射针1在使用过后，将护套2转向注射针1，到位时倒勾板202勾住针管102，同时在这过程中，所述注射针容置腔201开口两侧的侧壁上卡钩203的斜面与针座101上的卡块103相互作用使得注射针容置腔201开口两侧的侧壁相互分开（由于注射针容置腔201为开口设置，具有一定的弹性变形量），在卡钩203滑过卡块103后注射针容置腔201两侧壁恢复，卡块103滑过卡钩203，卡块103上的锁条1031进入卡钩203上的凹槽2031中而将注射针1与护套2相互锁住。
