Abstract

本实用新型涉及医疗器械领域,具体地说是一种注射器负压锁定装置,包括注射器负压锁定装置,其特征是该装置采用不锈钢制成,由炳部和尾部组成。尾部可以固定在注射器活塞近端,从而使装置可以随着注射器活塞的拉动而移动。注射器活塞拉出后,该装置炳部可以卡在注射器外套和注射器活塞之间,而起锁定作用。

Description

注射器负压锁定装置 
技术领域
本实用新型涉及医疗器械领域,具体地说是可辅助负压腔隙中液体抽取的一种注射器负压锁定装置。 
背景技术
众所周知,临床进行浆膜腔积液和引流液等负压腔隙中液体抽取时,由于负压的存在,可以造成液体抽取困难。 
目前常用的注射器负压锁定装置存在设计复杂,操作不方便,成本较高等缺点。 
发明内容
本实用新型为克服现有技术的不足,提出一种操作方便、使用效果好的注射器负压锁定装置。 
本实用新型采用的技术措施是: 
注射器负压锁定装置,包括注射器负压锁定装置,特征是采用不锈钢制成,由炳部和尾部组成,尾部设有卡槽。 
附图说明
附图是本发明的结构示意图。 
附图标记:炳部1、尾部2。 
具体实施方式:
注射器负压锁定装置,包括炳部1,其特征是炳部1为拱形,可以与注射器外套紧密接触,尾部2有卡槽,可以固定在注射器活塞的近端。 
使用时,尾部2通过卡槽固定于注射器活塞的近端,炳部紧密接触于注射器外套外。抽拉注射器活塞,该装置也随之移动,当炳部移动出注射器外套时,可以卡在注射器外套和注射器活塞之间,此时该装置开始承受负压。本实用新型具有操作简单,设计合理,反复使用等显著特点。
