Abstract

本实用新型公开了一种止回流阀,其特征在于它包括弹性软管(1),弹性软管(1)上设有侧面割口(3),弹性软管(1)的一端设有封堵(2),本实用新型避免了诊断试剂盒中废液袋内的液体泄漏,防止了环境污染。

Description

一种止回流阀
(一)技术领域:本实用新型涉及一种阀,尤其涉及一种止回流阀。
(二)背景技术:目前,诊断试剂盒中进入废液袋的进口管,无任何止流装置,这样废液袋内的液体容易因倒流而造成泄漏,污染了环境,危害了人们的身体健康。
(三)发明内容:本实用新型的目的在于克服上述已有技术的不足而提供一种避免废液泄漏,防止环境污染的止回流阀。
本实用新型的目的可以通过如下措施来达到:一种止回流阀,其特征在于它包括弹性软管1,弹性软管1上设有侧面割口3,弹性软管1的一端设有封堵2。
本实用新型同已有技术相比可产生如下积极效果:由于本实用新型设在诊断试剂盒中进入废液袋的进口管处,当管内压力大于管外压力时侧面割口打开,液体流入袋内,当管内压力小于管外压力时由于管自身弹性割口闭合,阻止液体流出,这样使容器、管路中液体单向流动,避免了废液的倒流,不会因为废液的泄漏而污染环境。
(四)附图说明:
附图为本实用新型的结构示意图。
(五)具体实施方式:下面结合附图对本实用新型的最佳实施方式作详细说明:
实施例:一种止回流阀(参见附图),它包括弹性软管1,弹性软管1上设有侧面割口3,弹性软管1的一端设有封堵2,使用时将弹性软管1未封口的一端与进口管紧密连接,保证接口处不漏即可。
