Abstract

本发明属于医疗器械领域,特别涉及一种回缩式持针器,包括持针基体和保护套,持针基体上部和下部分别设置定位扣,底部设有按柄,位于上部的定位扣设置为平面凸起扣,下部的定位扣为弹性卡扣,弹性卡扣为斜面凸起扣,弹性卡扣底部设有弹性按钮,保护套下部对应持针基体上部和下部的定位扣设置定位卡口,定位卡口下部设置弹性按钮放置孔。采血完毕后,手动按弹性按钮并向后拉动,可实现安全功能,使采血针全部进入保护套,从而确保针头不外露,避免刺伤及交叉感染,保证了安全采血。

Description

回缩式持针器
技术领域
本发明涉及一种回缩式持针器,主要与笔杆式采血针配套使用,用于进行静脉血液的贮存和采集,属于医疗器械领域。
背景技术
由于真空采血技术的优势,已得到医院及病患的肯定和认可。一次性真空采血装置分为两部分,即一次性采血针和一次性真空采血管。据报道世界发达国家人均使用采血管的数量为5~6支,甚至更高,中国人口之庞大,使用真空采血技术的需求会越来越大,随之安全采血问题就会暴露,极易造成血液病毒的传染,据统计健康的医务人员患血源性传染病80~90%是由针尖刺伤所致,被刺伤的医务人员中护士占80%,安全采血越来越得到社会和医院的重视,可有效降低传染病发病率,推动传染病预防工作,减少各种疾病给经济造成的重大损失;同时,可以降低非安全采血对公众身体健康的危害。
发明内容
本发明要解决的技术问题是:提供一种能够对采血针进行安全方便的使用、避免刺伤及交叉感染、保证医护人员及被采血者安全的回缩式持针器。
本发明所述的回缩式持针器,包括持针基体和保护套,持针基体上部和下部分别设置定位扣,底部设有按柄,位于上部的定位扣设置为平面凸起扣,下部的定位扣为弹性卡扣,弹性卡扣为斜面凸起扣,弹性卡扣底部设有弹性按钮,保护套下部对应持针基体上部和下部的定位扣设置定位卡口,定位卡口下部设置弹性按钮放置孔。
采血完毕后,用手按弹性按钮,待弹性卡扣与定位卡口配合脱离后,向后拉动持针基体,直至上部的定位扣与保护套定位卡口配合,这时持针基体可带动采血针进入保护套中,实现防针刺功能。
所述的弹性按钮置于按柄结构的上部,保护套与持针基体之间设有间隙。回缩式持针器在用于采血之前的初始状态是弹性按钮结构置于按柄的上部。
弹性卡扣顶部与持针基体为一体式结构,其余部分与持针基体之间设有间隙。容易制作,且便于操作弹性卡扣。
本发明的有益效果是:
采血完毕后,手动按弹性按钮并向后拉动,可实现安全功能,使采血针全部进入保护套,从而确保针头不外露,避免刺伤及交叉感染,保证了安全采血。
附图说明
图1是本发明采血前的结构示意图。
图2是图1中保护套的结构示意图。
图3是图1中持针基体的结构示意图。
图4是本发明采血完毕后的结构示意图。
图中:1、保护套 2、持针基体 3、定位卡口 4、弹性按钮放置孔 5、平面凸起扣6、弹性卡扣 7、弹性按钮 8、按柄。
具体实施方式
下面结合附图对本发明做进一步描述:
如图1~图4所示,本发明所述的回缩式持针器,包括持针基体2和保护套1,持针基体2上部和下部分别设置定位扣,底部设有按柄8,位于上部的定位扣设置为平面凸起扣5,下部的定位扣为弹性卡扣6,弹性卡扣6为斜面凸起扣,弹性卡扣6底部设有弹性按钮7,保护套1下部对应持针基体2上部和下部的定位扣设置定位卡口3,定位卡口3下部设置弹性按钮放置孔4。弹性按钮7置于按柄8结构的上部,保护套1与持针基体2之间设有间隙。弹性卡扣6顶部与持针基体2为一体式结构,其余部分与持针基体2之间设有间隙。
产品由保护套1、持针基体2组成,持针基体2的弹性卡扣6与保护套的定位卡口3配合,这样可使持针基体2与保护套1组成成一体,且牢固度可靠。更换采血管时,拇指抵住采血管底部,食指和中指扣在按柄8上,拇指稍用力按,采血管即可装入,采血完毕后,用手按弹性按钮7,待弹性卡扣6与定位卡口3配合脱离后,向后拉动持针基体2,直至平面凸起扣5与保护套定位卡口3配合,这时持针基体2可带动采血针进入保护套1中,实现防针刺功能。
