Abstract

一种一次性静脉采血针，属于医疗器械技术领域。由针头、针筒、活塞、针栓、针头帽、松紧套构成，针头连接在针筒前端的针头连接座上，针头外面套有针头帽，针筒内部的密封活塞与针栓固定连接，其特征在于针头帽前端外壁上套有与针头连接座相适配的松紧套，在针筒尾部内壁上设有一条与针筒末端相通的通气凹槽。优点是：盛血样的采血针筒可直接放入离心机内分离血清，克服了现有采血器在注血过程中因操作不慎造成溶血，影响检验结果的问题，保证了检验结果的准确性；同时由于省去了一次性试管，降低了验血成本，减少了环境污染。

Description

一次性静脉采血针
技术领域
本实用新型属于医疗器械技术领域，具体的说是一种一次性静脉采血针。
背景技术
现在的采血检验过程一般是这样的，先用采血器采集血样，再将血样注入试管(或其它盛器)，然后将血样用离心机分离血清后进行各种项目的检验。这样做既烦琐，又容易因注血操作不慎引起溶血，影响检验结果的准确性。
发明内容
本实用新型的目的在于克服上述的不足，提供一种采血化验简便，不易引起溶血，保证检测结果准确的一次性静脉采血针。
本实用新型的目的是这样实现的：该一次性静脉采血针由针头、针筒、活塞、针栓、针头帽、松紧套构成，针头连接在针筒前端的针头连接座上，针头外面套有针头帽，针筒内部的密封活塞与针栓固定连接，在针头帽前端外壁上套有与针头连接座相适配的松紧套，在针筒尾部内壁上设有一条与针筒末端相通的通气凹槽。
在具体使用本实用新型时，首先按常规过程采集血样，当活塞退至通气凹槽前端时，取下针头，将松紧套套在针头连接座上，竖起针筒，针头连接座向下，继续向上抽拉活塞，当活塞全部经过通气凹槽前端时，针筒内部空腔通过通气凹槽与大气相通，负压自动解除，活塞可轻易拔出，这时把针筒直接放入到离心机内分离血清即可。由于松紧套紧套在针头连接座上，不必担心它会因离心力而脱落。
本实用新型的优点：由于盛血样的采血针筒可直接放入离心机内分离血清，从而克服了现有采血器在注血过程中因操作不慎造成溶血，影响检验结果的问题，保证了检验结果的准确性；同时由于省去了一次性试管，降低了验血成本，减少了环境污染。
附图说明
附图为本实用新型沿中心线的剖视图。
具体实施方式
以下结合附图对本实用新型作进一步的详细描述：该一次性静脉采血针由针头1、针筒2、活塞3、针栓4、针头帽5、松紧套6构成，针头1连接在针筒2前端的针头连接座上，针头1外面套有针头帽5，针筒2内部的密封活塞3与针栓4固定连接，在针头帽5前端外壁上套有与针头连接座相适配的松紧套6，在针筒2尾部内壁上设有一条与针筒2末端相通的通气凹槽7。
