Description

一种安全的蝴蝶型静脉输液针 技术领域
本实用新型涉及一种医疗器械，尤其涉及一种临床穿刺输液用的静脉输液针。
背景技术
蝴蝶型静脉输液针是目前已经广泛应用的一种临床输液装置，相比传统的输液设备，蝶型手柄的两翼设计，在用胶布固定静脉输液针位置时更牢固可靠。
但现有技术中的蝴蝶型静脉输液针，还存在有安全隐患，即处理废弃留置针时，其针头暴露，容易扎到医务人员，从而造成感染，其后果可能十分严重。
技术问题
本实用新型的目的是，提供一种结构简单，废弃时针头可以缩回针套内，避免扎到医务人员，杜绝医源性感染的，安全的蝴蝶型静脉输液针。
技术解决方案
为达到上述目的，本实用新型采用的技术方案为：一种安全的蝴蝶型静脉输液针，它由带碟形手柄的针头和安全外壳组成，所述安全外壳为中空结构，其特征在于 : 所述安全外壳的底座上设有针头移动导槽，所述底座与带碟形手柄的针头的尾部分别设有相互配合的卡扣和卡槽。
所述底座前部开放，其头部设有环形保护圈，中部设有夹紧栏。
所述带碟形手柄的针头的尾部设有与底座的夹紧栏配合的凸台。
有益效果
本实用新型所产生的有益效果为：静脉输液针废弃后，通过蝴蝶型侧翼将针头往后拉动，可使其针头缩至安全外壳内，并且通过卡扣结构锁死，避免针头外露，防止医源性感染。在针头使用的穿刺过程中，可以通过夹紧栏固定针头位置，使其不易前后移动与转动。
