Description

安全自毁式注射器
技术领域：
本实用新型涉及一种安全自毁式注射器，属于医疗器材技术领域。
技术背景：
本实用新型作出以前，在已有技术中，注射器主要由针管、针座、针筒、活塞、芯杆等组成。该种结构的注射器，芯杆和针座不能自动锁住，也不能自动回抽针管，而达到安全自毁一次性使用的目的。从使用性能上来讲，由于不具备一次性使用的特征；即存在重复使用的可能性，给交叉感染疾病留下了隐患，同时使用过的注射器在后处理过程中，易划伤人，造成新的感染机会。
技术内容：
本实用新型的目的在于克服上述不足之处，从而提供一种结构简单，紧凑，合理；操作简单，使用方便，当注射药结束后能回抽针管，并能达到安全自毁一次性使用的安全自毁式注射器。
本实用新型的主要解决方案是这样实现的：
其主要采用针管1安装在针座2的内孔内，针座2套上密封圈4装在外套5前端的孔内，芯杆7前端套上活塞6安装在外套5内，其特征是在外套5前端套有锁紧装置。锁紧装置是采用在外套5前端上开有槽，制成1至2个以上偏心圆弧，套上锁紧环3，锁紧环3内圈制有与外套5上偏心圆弧相对应的1至2个以上凸台。
附图说明：
图1为本实用新型结构示意图：
图2为本实用新型第一种锁紧装置A-A剖视图：
图3为本实用新型第二种锁紧装置B-B剖视图：
图4为本实用新型第三种锁紧装置C-C剖视图：
具体实施方式：
下面本实用新型将结合附图中的实施例作进一步描述：
实施例一：
本实用新型主要采用针管1粘结在针座2的内孔内，针座2套上密封圈4装在外套5前端的孔内。图2所示为本实用新型第一种锁紧装置；采用在外套5上套有锁紧装置。锁紧装置是采用在外套5前端开有数条槽，并制成1至2个以上偏心圆弧，套上锁紧环3。锁紧环3内圈上制有与外套5上偏心圆弧相对应的一至2个以上凸台。当旋转锁紧环3时，偏心圆弧向圆中心位移，锁紧环3松开针座2。
本实用新型工作原理：当注射药液时，芯杆7带动活塞6向下推时，在针座2上制有的凸尖9(凸尖9也可以不用)顶住活塞6，(此时药液尚未用完)，当芯杆7继续下移时，芯杆7前端装有圆锥体8，利用材料的塑性变形8压入在针座2的空腔10内，圆锥体8与针座2的空腔过盈为0.02～0.8mm，使芯杆7和针座2锁住。上面所述的圆锥体可以制成圆弧体或半圆体或圆台体。
拧松锁紧环3，回抽芯杆7，芯杆7带动针管1、针座2、密封圈4、活塞6退至外套5内，然后折断芯杆7达到安全和自毁两种功能。
实施例二：
本实用新型第二种锁紧装置如图3所示：采用在锁紧环3内圈上制有数条槽，并制成1个至2个偏心圆弧，在外套5上制有与锁紧环3内圈上偏心圆弧相对应的凸台，锁紧环3套在外套5上，旋转锁紧环3，使偏心圆弧向圆中心位移，锁紧环3松开针座2。
实施例三：
本实用新型第三种锁紧装置如图4所示：采用在锁紧环3内圈制有内螺纹，外套5上制有外螺纹，锁紧环3旋在外套5上用于锁紧针座2。
本实用新型与已有技术相比具有以下优点：
本实用新型结构简单，紧凑，合理；制作成本低，工艺简便；操作简单，使用方便；能达到回抽针管，安全自毁一次性使用；不会发生交叉感染，在后处理过程中，不易划伤人，有利于人们的身体健康。
