Description

一种易见回血的输液器 技术领域
本发明属于医用输液器技术领域。
背景技术
医用一次性输液器是目前常用的医疗器具之一， 其基本结构由输液 针、 滴管、 输液管、 调节开关和注射针头组成。 在进行静脉注射之前， 需 使滴管液平以下至注射针头的管道内充满输入液再进行注射， 但由于输液 管中充满液体， 注射针头进入静脉后不易见到血液回流现象， 故操作者难 以确定针头是否已进人静脉； 常用的解决办法是挤压输液管， 排出部分液 体， 形成负压以利于观察回血； 但如果注射针头未进人静脉， 排出的液体 就会进入血管周围组织， 而使血管移位、 下沉等， 增加进一步穿刺的难度， 或造成局部肿起， 需重新更换注射位置， 增加患者的痛苦和操作麻烦， 因 此这是一个亟待解决的技术问题.
发明概述
本发明旨在提出一种易见回血的输液器， 达到既易见回血现象、 又能 避免输入液误人血管周围组织的效果。
本发明提出的一种易见回血的输液器， 包括输液针、 滴管、 输液管、 调节开关、 注射针头接头和注射针头， 其特点是在滴管以下至注射针头之 间的输液管增加至少一个管外压迫器
压迫器形式多种多样， 可为钳夹或套帽或扣带， 或增加另一调节开关， 或通过至少一面有一个以上孔道的管道加塞子或扣子； 也可把压迫器与调 节开关合并， 即在同一个开关底板下部再安装一调节螺钉、 或扣带、 或套 帽、 或钳夹、 或至少有一段长出原开关的底板、 侧板等， 也可以同样方式 将压迫器与注射针接头、 或与滴管合并。
由于本发明提出的一种易见回血的输液器， 包括输液针、 滴管、 输液 管、 调节开关、 注射针头接头和注射针头， 其特征是在滴管以下至注射针 头之间的输液管增加至少一个管道外压迫器， 压迫器的形式多种多样， 可 另增加调节开关、 或钳夹、 或套帽等， 也可把压迫器与调节开关、 或与滴 管合并， 使用时将滴管以下至注射针头的管道充满输入液， 关闭调节开关 阻断液流， 扣紧调节开关下方的压迫器， 从注射针头处滴出数滴液体后， 再进行注射， 然后， 松开压迫器， 使输液管中形成一真空段， 若注射针头 已进人静脉， 则容易见到明显回血现象， 若注射针头未进入静脉， 则可把 针头沿静脉方向继续穿刺， 直至出现回血， 完成注射过程； 本发明的输液 器能提高静脉注射的操作技术， 达到既易见回血， 又能避免输入液误入血 管周围组织的效果。
附图的简述
以下结合附图中所示的实施例对本发明作进一步描述。
