Abstract

本实用新型公开了一种负压穿刺针,包括针头、针筒、针筒内与注塞相连的针芯组成,其特征在于,在所述的针芯上按一定间隔设有数个卡口,在所述的针筒上设有与所述的卡口相匹配的卡块。由于本实用新型负压穿刺针在进入体腔或血管之前针筒内能形成固定负压,故操作简便、准确。排除了对患者脏器造成误伤的可能。

Description

负压穿刺针
本实用新型涉及一种胸腔穿刺用负压穿刺针。
胸腔穿刺是诊断和治疗胸部疾患的主要手段之一,但现有所用穿刺针操作时,需要双手操作,一手固定穿刺针及针管,另一手在进针的同时,向外抽针芯,使其形成负压,边进针边抽吸,给操作带来困难,且有误伤脏器的可能,有时会造成严重并发症,尤其是心包穿刺。总之,现有穿刺针的缺陷是:操作不便,易对患者脏器造成误伤。
本实用新型是针对现有技术的不足,提供一种操作简便,不易对患者脏器造成误伤的负压穿刺针。
本实用新型的目的是这样实现的,负压穿刺针包括针头、针筒、针筒内与注塞相连的针芯组成,其特征在于,在所述的针芯上按一定间隔设有数个卡口,在所述的针筒上设有与所述的卡口相匹配的卡块。
由于本实用新型负压穿刺针在进入体腔或血管之前针筒内能形成固定负压,故操作简便、准确。排除了对患者脏器造成误伤的可能。
附图为负压穿刺针结构示意图。
下面结合附图对本实用新型作进一步详细描述。在穿刺针筒1尾端做一长方形小孔,插入一个大小与其相适应的卡块2,将针芯3按不同负压要求做出卡口4,操作时,当针头5进入皮下组织后,即抽动针芯3,将卡口4对准卡块2处,将卡块2按下插入卡口4将针芯3固定,形成负压。此时可单手进针,当针头5刺入体腔内,即有积液、积血、积脓或血液等液体进入针筒1内,穿刺成功。下一步可以放液或放置引流管引流。故负压穿刺针操作简单,单手即可完成;穿刺准确,只要定位准确并发症极低,且误伤脏器的机率大大降低。
