Abstract

粉针注射器，包括安装有针头的针筒及药剂瓶，药剂瓶分为二个腔室，腔室间及瓶口安装有密封装置；针筒的乳头部分插在瓶口的密封装置卡孔处，针筒的针头安装在药剂瓶的外腔室；针筒与双室瓶之间安装有防止二者相对运动的保险装置。采用双室瓶的结构，使整个粉针注射器的构造简单、成本低，解决了现有技术的构件多、成本高的不足，有利于推广应用。注射器使用时，只要破坏了针筒与双室瓶之间的保险装置，就可以推进针筒，使针头插入双室瓶的内腔室，再推进针筒的推杆，使液剂与粉剂混合，从而可以进行注射。

Description

粉针注射器
                           技术背景
目前的粉针注射器一般也由粉剂瓶及针筒组成，但是粉剂瓶为单腔室结构，采用了这一结构后，粉剂瓶与针筒之间的构件制造复杂，成本较高，不利于广泛应用。
                           技术内容
粉针注射器，包括安装有针头的针筒及药剂瓶，其特征在于药剂瓶分为二个腔室，腔室间及瓶口安装有密封装置；针筒的乳头部分插在瓶口的密封装置卡孔处，针筒的针头安装在药剂瓶的外腔室；针筒与双室瓶之间安装有防止二者相对运动的保险装置。采用双室瓶的结构，使整个粉针注射器的构造简单、成本低，解决了现有技术的构件多、成本高的不足，有利于推广应用。注射器使用时，只要破坏了针筒与双室瓶之间的保险装置，就可以推进针筒，使针头插入双室瓶的内腔室，再推进针筒的推杆，使液剂与粉剂混合，从而可以进行注射。
上述的粉针注射器，其特征在于双室瓶的双室之间的密封装置为中间薄、四周厚普通安瓿塞。这种结构是最常用的一种医用密封结构。
上述的粉针注射器，其特征在于针筒体与注射推进器之间安装有防止二者相对运动的保险装置。主要是为了防止本产品未使用时，注射推进器因为震动等原因进入针筒内，破坏了密封装置，使产品不可用。
上述的粉针注射器，其特征在于针筒与双室瓶之间的保险装置是这样构成的：在针筒与双室瓶之间安装一卡圈，卡圈两端分别与双室瓶及针筒顶托。用卡圈顶住双室瓶及针筒，使二者不能发生相对运动，从而保护了产品的可使用。
上述的粉针注射器，其特征在于所述的卡圈的竖向合缝处由粘带相连。采用这一结构，可以简单地拆开粘带，即可使用。
上述的粉针注射器，其特征在于所述的卡圈上竖向分隔固定有至少二条支撑条。横向拆开卡圈，由于支撑条是竖向的，可以很容易地展开卡圈，从而使之脱落。
上述的粉针注射器，其特征在于所述的卡圈底侧的内端面上开槽，双室瓶的瓶沿嵌入该开槽内。
上述的粉针注射器，其特征在于所述的卡圈上侧的内端面上开槽，针筒的下端面嵌入该开槽内。
上述的粉针注射器，其特征在于所述的针筒体与注射推进器之间的保险装置是这样构成的：在针筒体的后端面上安装挡杆，注射推进器上开槽，挡杆插入该开槽内。挡杆是为了防止本产品未使用时，注射器的推杆未使用时进入针筒，从而破坏了密封装置。
                           附图说明
图1为本实用新型结构示意图。
                           具体实施方式
实施例1：
参照附图，一种粉针注射器，包括安装有针头11的针筒2及药剂瓶，药剂瓶分为二个腔室，外腔室6及粉剂腔室7，腔室6、7间及瓶口安装有密封装置；针筒的乳头20部分插在瓶口的密封装置即密封塞5的卡孔处，针筒的针头安装在药剂瓶的外腔室；针筒与双室瓶之间安装有防止二者相对运动的保险装置。双室瓶的双室之间的密封装置为中间薄、四周厚普通安瓿塞。
针筒体与注射推进器之间安装有防止二者相对运动的保险装置。保险装置是这样构成的：在针筒与双室瓶之间安装一卡圈4，卡圈两端分别与双室瓶及针筒顶托。
卡圈的竖向合缝处由粘带相连。卡圈上竖向分隔固定有至少二条支撑条3。
针筒体与注射推进器之间的保险装置是这样构成的：在针筒体的后端面上固定挡杆9，注射推进器1上开槽8，挡杆插入该开槽内。
使用时，撕开卡圈的粘带，横向拆开卡图，将卡圈从本产品上剥离，向粉剂腔室推动针筒，使针筒乳头向粉剂腔室方向挤入，从而使针头刺入双室瓶的内腔室和粉剂腔室之间的安瓿塞；再推动注射推杆，使推杆破坏针筒的挡杆，突破挡杆的限制，这时存储在针筒内的水剂从针头注入双室瓶的粉剂腔室，再摇动产品，使水剂和粉剂混合，再从双室瓶中拨出针筒用于注射。
实施例2：
与实施例1不同的是，本实施例在卡圈底侧的内端面上开槽10，双室瓶的瓶沿嵌入该开槽内。
实施例3：
与实施例1不同的是，本实施例卡圈上侧的内端面上开槽，针筒的下端面嵌入该开槽内。
