一种静脉采血装置
本技术属于医疗器械,具体涉及一种静脉采血装置。
技术介绍
静脉采血是一种较为常见的采血方式,其中一种方式是直接将采血针刺入静脉血管内,然后利用负压将血压输送至采血吸管内。这种静脉采血结构比较简单,但是对操作人员的技能要求较高,在操作时,很容易出现采血针刺不到位的情况。
技术实现思路
本技术的目的就在于为了解决上述问题而提供一种静脉采血装置。本技术通过以下技术方案来实现上述目的:一种静脉采血装置,包括采血吸管、静脉采血针、导向针套及连接座;所述导向针套的一端与所述连接座固定连接,且另一端设置为针尖结构;所述导向针套内设置有导向针槽,所述导向针槽贯通整个导向针套,所述导向针套的外表面设置有条形槽,所述条形槽处设置有滑块;所述静脉采血针设置于所述导向针槽内,所述静脉采血针的针尖部从所述导向针套的针尖端穿出,所述滑块挤压并固定在所述静脉采血针上;所述连接座内设置有弹性驱动腔、缓冲腔、软质连接管、弹簧和硬质连接管,所述软质连接管位于所述缓冲腔内,所述弹簧设置于所述弹性驱动腔内,所述静脉采血针经过所述弹性驱动腔穿至所述弹性驱动腔内并与所述软质连接管的一端连接,所述软 ...
