Abstract

本发明涉及一种医疗卫生注射器，包括针筒、橡胶垫及活塞管，橡胶垫固定安装在活塞管末端，橡胶垫和活塞管一起滑动安装在针筒内部，橡胶垫表面设有锥形凹槽，在锥形顶点处设有与活塞管内部连通的排气管路，活塞管内设有小橡胶垫，小橡胶垫通过活塞杆连接拨动件，拨动件设置在活塞管侧壁的开口槽处。本发明的优点体现在：可将空气存入橡胶垫的锥形凹槽处，并通过活塞管内的活塞杆将空气吸入活塞管内部，使得针筒内再无空气杂质，提高了注射药剂的纯净度。

Description

医疗卫生注射器
技术领域
本发明涉及医疗器械技术领域，具体涉及一种医疗卫生注射器。
背景技术
注射器是一种常见的医疗用具，被广泛用于配置药物或者向患者身体内注射药物。但是常规注射器的缺点在于，由于针头会附有空气，使用注射器抽取药物时，空气会混杂进入针筒内部，虽然可以通过控制注射剂量避免空气被注射入人体，但是需要医生在注射时十分留意。
发明内容
本发明的目的是针对现有技术中的不足，提供一种可排出空气的医疗卫生注射器。
为实现上述目的，本发明公开了如下技术方案：
医疗卫生注射器，包括针筒、橡胶垫及活塞管，橡胶垫固定安装在活塞管末端，橡胶垫和活塞管一起滑动安装在针筒内部，橡胶垫表面设有锥形凹槽，在锥形顶点处设有与活塞管内部连通的排气管路，活塞管内设有小橡胶垫，小橡胶垫通过活塞杆连接拨动件，拨动件设置在活塞管侧壁的开口槽处。
进一步的，在针筒末端设有凸台，凸台内表面为弧形结构。
进一步的，所述凸台的内表面附有防滑膜。
进一步的，所述防滑膜为医用橡胶膜。
进一步的，所述活塞管末端表面附有防滑膜。
进一步的，所述活塞管末端的防滑膜为医用橡胶膜。
本发明公开的一种医疗卫生注射器，具有以下有益效果：
本发明可将空气存入橡胶垫的锥形凹槽处，并通过活塞管内的活塞杆将空气吸入活塞管内部，使得针筒内再无空气杂质，提高了注射药剂的纯净度。
附图说明
图1是本发明的结构示意图；
其中：
1-针筒，2-橡胶垫，3-排气管路，4-小橡胶垫，5-凸台，6-活塞管，7-活塞杆，8-拨动件。
具体实施方式
下面结合实施例并参照附图对本发明作进一步描述。
请参见图1。
实施例1
医疗卫生注射器，包括针筒1、橡胶垫2及活塞管6，橡胶垫2固定安装在活塞管6末端，橡胶垫2和活塞管6一起滑动安装在针筒1内部，橡胶垫2表面设有锥形凹槽，在锥形顶点处设有与活塞管6内部连通的排气管路3，活塞管6内设有小橡胶垫4，小橡胶垫4通过活塞杆7连接拨动件8，拨动件8设置在活塞管6侧壁的开口槽处。
本发明在使用时，首先拉动活塞管6抽取药剂，不可避免的，针头部分的空气进入针筒1内形成气泡，调整注射器至针头向下，气泡上升至锥形凹槽处，拨动拨动件8，拨动件8带动活塞杆7及小橡胶垫4抽取针筒内的气泡，抽取气泡完成后，推动活塞管6进行药剂注射。
实施例2
本实施例中，在针筒1末端设有凸台5，凸台5内表面为弧形结构。该弧形结构可便于医护人员操作注射器。其余技术方案与实施例1一致，且本实施例中所采取的技术方案也适用于其他实施例。
实施例3
本实施例中，所述凸台5的内表面附有防滑膜。防止使用注射器的过程中滑脱。其余技术方案与实施例2一致，且本实施例中所采取的技术方案也适用于其他实施例。
实施例4
本实施例中，所述防滑膜为医用橡胶膜。保证本注射器的安全卫生。其余技术方案与实施例3一致，且本实施例中所采取的技术方案也适用于其他实施例。
实施例5
本实施例中，所述活塞管6末端表面附有防滑膜。防止使用注射器的过程中滑脱。其余技术方案与实施例1一致，且本实施例中所采取的技术方案也适用于其他实施例。
实施例6
本实施例中，所述活塞管6末端的防滑膜为医用橡胶膜。保证本注射器的安全卫生。其余技术方案与实施例5一致，且本实施例中所采取的技术方案也适用于其他实施例。
以上所述仅是本发明的优选实施方式，而非对其限制；应当指出，尽管参照上述各实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，其依然可以对上述各实施例所记载的技术方案进行修改，或对其中部分或者全部技术特征进行等同替换；而这些修改和替换，并不使相应的技术方案的本质脱离本发明各实施例技术方案的范围。
