槽缝式保护套的开放式留置针制造技术

一种适用于血管内的医疗器械，特别是一种在临床医疗上防针尖刺伤防血污染的槽缝式保护套的开放式留置针，针座（3.1）通过导向连接筋（3.1.3）与操作翼片或操作捏耳（3.1.2.1）连接，针管保护套（1）是一长形中空壳体，一侧壁或者对应的两侧壁具有一定长度的滑动槽缝（1.1.1），针管保护套从留置针后端套插进入针座并向前滑动直至二者之间的后卡触装置卡触连接，此时针管保护套完全遮蔽针尖；向后拉动针管保护套、后卡触装置脱离卡触、直至凸卡与针座卡触形成前卡触并止退，穿刺后针管组件相对针管保护套移动并向后退入针管保护套中直至后卡触装置再次卡触连接，此时针管保护套再次完全遮蔽针尖。优点在于，实时对针管以及针尖实施有效防护，防止了意外伤人和血液污染环境；实用性强，便于推广应用。

Open indwelling needle for slot type protective sleeve

A suitable intravascular medical device, in particular to a clinical medical needle stab anti pollution prevention blood slot open type protective sleeve needle, needle (3.1) connecting bars through the guide (3.1.3) and operation wings or operation of pinching ear (3.1.2.1) connection, Paul (needle sheath 1) is a long shaped hollow shell, one side wall or sliding groove on both sides of the wall corresponding with a certain length (1.1.1), the gap between the needle tube protective sleeve from the catheter inserted into the needle seat and back sliding forward until the two after the card card touch touch device connected to the needle protective sleeve completely covered tip; pull back the needle protective sleeve, after the device out of touch, touch card card card and card holder until the convex contact card before the formation of contact and check, after the puncture needle assembly relative needle protective sleeve and moving back into the needle protective sleeve until after contact with the card When the second card is connected, the needle tube cover is completely covered with the needle tip. The advantage is that it can effectively protect the needle tube and needle point in real time, and prevent the accidental injury and the pollution of the blood. It is practical and convenient for popularization and application.
