There a sealing means between the chambers and at the opening of the bottle. The nipple section(20) of the syringe barrel(2) is inserted into a clipping bore of the sealing means at the opening of the vial. The needle(11) of the syringe barrel(2) is mounted in the upper chamber(12) of the medication vial. A safety means is mounted between the syringe barrel(2) and the double-chamber, which prevents the relative movement of them. When the syringe is being used, as long the safety means between the syringe barrel(2) and the dual­chamber is broken, the syringe barrel(2) can be pushed to allow the needle(11) to be inserted into the lower chamber(7). As the pushing rod(1) of the syringe barrel(2) is pushed further, the solvent(14) is allowed to mixed with the powder(13). After the solution is uniform by shaking, injection can be performed with the needle being pulled out. Therefore, the syringe of the present invention has a simple structure and can be operated conveniently. Moreover, it will not cause recontamination, and it is safe and trustable to use.

实施例 1 :  Example 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 瓶分为上下两个腔室， 上腔室 12为一空腔室， 下腔室 7为粉剂腔室， 上下腔室 12、 7间安装有中间薄、 四周厚的普通密封安瓿塞 6， 瓶口安装有密封塞 5; 针 筒的乳头 20部分插在瓶口的密封塞 5的卡孔处， 针筒的针头安装在药剂瓶的上 腔室 12内。 Referring to the drawings, a powder needle syringe includes a syringe 2 and a medicine bottle on which a needle 11 is installed. The medicine bottle is divided into two upper and lower chambers, an upper chamber 12 is an empty chamber, and a lower chamber 7 is a powder chamber. , Upper and lower chambers 12, 7 ordinary thin ampule plugs 6 with a thin middle and thick circumference are installed, and the bottle mouth is equipped with a sealing plug 5; the nipple 20 of the syringe is inserted into the card hole of the sealing plug 5 of the bottle, and the needle of the syringe is installed In the upper chamber 12 of the vial.
针筒 2与双室瓶之间安装有防止两者相对运动的保险装置。该保险装置是这 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联 接。卡圈 4的竖向合缝处由粘带相连。卡圈 4上竖向分隔固定有至少两条支撑条 3。  A safety device is installed between the syringe 2 and the double chamber bottle to prevent relative movement between the two. The safety device is constituted as follows: A retaining ring 4 is installed between the syringe and the double chamber bottle, and the two ends of the retaining ring are respectively connected with the double chamber bottle and the syringe. The vertical joints of the collar 4 are connected by adhesive tape. At least two support bars 3 are vertically fixed on the collar 4.
在针筒 2与注射推进器 1之间也设置有保险装置，该保险装置是这样构成的： 在针筒体的后端面上固定挡杆 9， 在注射推进器 1上开设槽 8, 所述挡杆 9插入 该槽 8内。  A safety device is also provided between the syringe 2 and the injection pusher 1, and the safety device is structured as follows: a retaining rod 9 is fixed on the rear surface of the syringe body, and a groove 8 is opened on the injection pusher 1, The blocking lever 9 is inserted into the groove 8.
使用时， 撕开卡圈 4的粘带， 横向撕开卡圈 4， 将卡圈 4从本产品上剥离， 向粉剂腔室 7推动针筒 2， 使针筒乳头 20向粉剂腔室 7方向挤入， 从而使针头 11刺穿双室瓶的上下腔室之间的密封塞 5后进入粉剂腔室 7内， 如图 2所示。 然后推动注射推杆 1， 使推杆 1破坏针筒的挡杆 9， 突破挡杆 9的限制， 这时存 储在针筒内的水剂 14从针头 11注入双室瓶的粉剂腔室 7， 当水剂注入完毕后， 震荡或者摇动产品，使水剂 14和粉剂 13充分混合，最后从双室瓶中拨出针筒即 可用于注射。  When in use, tear the adhesive tape of the collar 4 and tear the collar 4 laterally, peel the collar 4 from the product, and push the syringe 2 toward the powder chamber 7, so that the nipple 20 of the syringe faces the direction of the powder chamber 7. Squeeze it in so that the needle 11 pierces the sealing plug 5 between the upper and lower chambers of the double chamber bottle and enters the powder chamber 7 as shown in FIG. 2. Then push the injection pusher 1 so that the pusher 1 breaks the stopper 9 of the syringe and breaks the limit of the stopper 9. At this time, the liquid agent 14 stored in the syringe is injected from the needle 11 into the powder chamber 7 of the double chamber bottle. After the liquid injection is completed, the product is shaken or shaken to fully mix the liquid 14 and the powder 13 and finally the syringe is pulled out of the double-chamber bottle for injection.
