Description

一种检验采血针
技术领域:
本实用新型涉及医疗检验用品,具体涉及一种检验采血针 。
背景技术:
在医学检验中,经常采集血液进行检验,目前一般是采用采血针抽取血液然后注入试管内进行检验,这样血液会暴漏在空气中,细菌容易进入,血液容易变质,造成检验结果不准确。
实用新型内容:
本实用新型的目的是提供一种新型检验采血针,它采血过程中不接触空气,保证了血液不受细菌感染,提高了检验结果的准确性。
为了解决背景技术所存在的问题,本实用新型采取以下技术方案:它包含针筒1、针头2、正单向阀3、逆单向阀4和试管5,正单向阀3设置在针筒1前端,正单向阀3的前端设置有针头2, 试管5通过逆单向阀4与针筒1连接。
本实用新型具有以下有益效果:它采血过程中不接触空气,保证了血液不受细菌感染,提高了检验结果的准确性。
附图说明:
图1为本实用新型的结构示意图。
具体实施方式:
参照图1,本具体实施方式采取以下技术方案:它包含针筒1、针头2、正单向阀3、逆单向阀4和试管5,正单向阀3设置在针筒1前端,正单向阀3的前端设置有针头2, 试管5通过逆单向阀4与针筒1连接。
本具体实施方式它采血过程中不接触空气,保证了血液不受细菌感染,提高了检验结果的准确性。
