Abstract

一种自毁型针尖可回缩安全注射器针座，它涉及一种皮下注射器针座。它由针座体(3)、带有斜面的凹形卡口(3－1)、内孔圆柱直面(3－3)和两个带有斜面的卡槽(3－2)组成，带有斜面的凹形卡口(3－1)设置在针座体(3)的内部，两个带有斜面的卡槽(3－2)均匀设置在针座体(3)的外部下端，带有斜面的凹形卡口(3－1)与针座芯(4)外部的圆锥斜面(4－2)相配合，不易泄漏药液，带有斜面的卡槽(3－2)与外套(5)上端的螺旋形凹槽(5－3)相配合，可以将针座(3)固定在外套5的前端，内孔圆柱直面(3－3)与针座芯(4)外部的圆柱面(4－3)相配合。本实用新型使针座与针座芯配合紧密，不易泄漏药液。

Description

一种自毁型针尖可回缩安全注射器针座
技术领域：
本实用新型涉及一种皮下注射器针座的改进，尤其是一种自毁型针尖可回缩安全注射器针座。
背景技术：
目前使用的最多的是一次性注射器，但这种注射器在使用后它的结构并没有改变，完全可以重复使用，造成了极大的安全隐患。近年又出现了自毁式注射器，此类注射器使用后会自行破坏或锁死而不可以重复使用，但它的针头还是外露的，虽避免了重复使用，但还是存在着安全隐患。中国专利号03278017.6公开了一种针尖可回缩安全型注射器，但其针座与针座芯之间配合不够紧密，会存在泄露药液的现象。
实用新型内容：
本实用新型的目的是提供一种自毁型针尖可回缩安全注射器针座，它能使针座与针座芯配合紧密，不易泄漏药液。
为了解决背景技术所存在的问题，本实用新型是采用以下技术方案：它由针座体、带有斜面的凹形卡口、内孔圆柱直面和两个带有斜面的卡槽组成，带有斜面的凹形卡口设置在针座体的内部，两个带有斜面的卡槽均匀设置在针座体的外部下端，带有斜面的凹形卡口与针座芯外部的圆锥斜面相配合，内孔圆柱直面与针座芯外部的圆柱面相配合，形成二次密封，增强密封性能，可以防止药液泄漏，带有斜面的卡槽与外套上端的螺旋形凹槽相配合，可以将针座固定在外套的前端。
本实用新型能使针座与针座芯配合紧密，不易泄漏药液。
附图说明：
图1为本实用新型安装在注射器内部的结构示意图，图2为本实用新型的立体结构示意图，图3为图2的俯视图，图4为图2的A-A向剖视图，图5为图2的立体剖视图。
具体实施方式：
参照图1-5，本具体实施方式采用以下技术方案：它由针座体3、带有斜面的凹形卡口3-1、内孔圆柱直面3-3和两个带有斜面的卡槽3-2组成，带有斜面的凹形卡口3-1设置在针座体3的内部，两个带有斜面的卡槽3-2均匀设置在针座体3的外部下端，带有斜面的凹形卡口3-1与针座芯4外部的圆锥斜面4-2相配合，内孔圆柱直面3-3与针座芯4外部的圆柱面4-3相配合，形成二次密封，增强密封性能，可以防止药液泄漏，带有斜面的卡槽3-2与外套5上端的螺旋形凹槽5-3相配合，可以将针座3固定在外套5的前端。
本具体实施方式能使针座与针座芯配合紧密，不易泄漏药液。
