Abstract

本实用新型公开了一种具有过滤功能的注射器，它是在注射器的针头和针筒之间增加一过滤器，所述过滤器包括可与针头相配合的接头、可与针筒相配合的接头以及两接头之间的过滤网。本实用新型的优点是结构简单，方便实用，装卸灵活，便于推广使用，从根本上杜绝了药液中的微小杂物进入人体所造成的危害。

Description

具有过滤功能的注射器
本实用新型涉及一种医疗器械，具体地说是一种注射器。
在临床护理工作中，肌肉注射和静脉注射是最为常见的操作之一。在抽吸药液时，安瓿内或密闭玻璃药瓶内的微小玻璃碎渣或破碎的橡皮会随着针头的吸入，进入针筒内，肉眼难以发现，可直接误入病人的体内，造成危害。
针对上述问题，本实用新型的目的是提供一种能够滤除微小杂物的注射器。
本实用新型的技术方案是在注射器的针头和针筒之间增加一过滤器，所述过滤器包括可与针头相配合的接头、可与针筒相配合的接头以及两接头之间的过滤网。
本实用新型的优点是结构简单，方便实用，装卸灵活，便于推广使用，从根本上杜决了药液中的微小杂物进入人体所造成的危害。
下面结合附图并通过实施例来进一步说明本实用新型。
图1是本实用新型的结构示意图。
图2是过滤器的结构示意图。
如图所示，一次性注射器包括针头1和针筒2，在针头1和针筒2之间增加过滤器3，该过滤器3与针头1和针筒2之间是可拆卸的，它包括可与针头相配合的接头4、可与针筒相配合的接头5以及两接头之间的过滤网6，接头4和接头5都是标准口径，它们与针头1和针筒2通过直接插接即可安装。使用时可以先将过滤器3安装在针头1和针筒2之间，抽吸药液时，即可将药液中的微小杂物过滤掉，注射时需将该过滤器拆去；也可以先不加过滤器，直接抽吸药液，在注射时将过滤器装上，同样也可将药液中的微小杂物过滤掉。

Claims (2)

1.一种具有过滤功能的注射器，包括针头(1)和针筒(2)，其特征在于针头(1)和针筒(2)之间还包括一过滤器(3)，所述过滤器(3)包括可与针头(1)相配合的接头(4)、可与针筒相配合的接头(5)以及两接头之间的过滤网(6)。
2.根据权利要求1所述的注射器，其特征在于所述过滤器(3)是可拆卸的。
