无菌混药注射器 技术领域
本发明涉及医疗器械领域的注射器, 特别是涉及一种集溶质、 溶媒和 注射器为一体的溶媒前置式无菌混药注射器, 还涉及一种溶媒另置式无菌 混药注射器。 背景技术
本申清人曾先后申请了多项预灌封注射器, 对传统注射器的构造进行 了较大的改进和创新, 它不但可以减少注射操作环节, 降低工作强度, 更 重要的是不会出现因配药差错而导致的医疗责任事故, 而且具有使用方便, 可自我注射的优点。但这些注射器大都是溶媒瓶与推柄接触, 而溶质瓶(必 须是卡式瓶)位于注射器前部, 当溶媒由于压力通过导通针进入溶质瓶后 实现混药, 然后由溶质瓶内推出药液。 虽然结构上有了较大改进, 产生了 一定的积极作用, 但还存在一些如使用不方便、 结构不尽合理之处。 比如 要同时具有导通针和注射针, 这样使制造成本不能降到最低, 生产工艺也 比较复杂。
与上述预灌封注射器不同, 本申请人于 2006年 4月 18 日向中国国家 知识产权局专利局提交的申请号为 200610042690. 2的专利申请 "溶媒前置 式无菌混药卡式瓶注射器" 中首次提出一种溶媒瓶前置的预灌封注射器。 该注射器的结构为溶质瓶与推柄接触, 而将溶媒瓶(及其滑动套)置于注 射器的前部, 这种结构不但可以实现在混药结束后, 拔除溶媒瓶(及其滑 动套) 即可实施注射操作, 而且将导通针和注射针合二而一, 既简化了混 药操作程序, 又筒化了注射器结构。
本申请人于 2006年 4月 18 日向中国国家知识产权局专利局提交的申 请号为 200620078828. X的专利申请 "卡式瓶水针剂预灌封注射器,, 中提出 一种用于水针剂药物的预灌封注射器。 该申请中对注射器推杆作了重大改 进, 首次披露了一种二级推杆结构, 可以显箸缩短推杆的长度, 不但操作 简便, 而且有利于减小包装尺寸, 方便运输与携带。
本申请人于 2006年 5月 25 日向中国国家知识产权局专利局提交的申 请号为 200620079041. 5的专利申请 "溶媒另置式无菌混药卡式瓶注射器" 中首次提出一种将溶媒瓶(及其滑动套)与注射器主体分开放置的预灌封 注射器。 该注射器的特点为只在进行混药操作时才将溶媒瓶(及其滑动套) 临时套接于注射器前端, 进一步缩短了注射器整体长度, 更有利于减小包 装尺寸, 方便运输与携带。

为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功 效,以下结合附图及较佳实施例, 对依据本发明提出的溶媒前置式无菌混药 注射器和溶媒另置式无菌混药注射器其具体实施方式、 结构、 特征及其功 效, 详细说明: δ口后。
1、 本发明的溶媒前置式无菌混药注射器实施方式
请参阅图 1至图 11所示, 本发明较佳实施例的溶媒前置式无菌混药注 射器, 其主要由滑动套 2、 溶媒瓶 3、 溶质瓶 8、 活塞 10、 外壳 9、 针头 5、 运针机构和推拉杆机构所组成, 其中:
滑动套 2为空心圆柱体, 其前端设有端盖 1 , 内部中段设有凸环 31。 溶媒瓶 3为西林瓶, 由与滑动套 1旋接或卡接的端帽 1封装在滑动套 2内, 瓶口向后, 瓶肩抵住滑动套 2内的凸环 31 ;
溶质瓶 8为卡式瓶, 活塞 10置于溶盾瓶 8瓶底的开口内;
外壳 9为空心圆柱体, 内部前端有环形台阶, 溶质瓶 8置于外壳 9内, 瓶口向前,瓶肩抵住外壳 9内部前端的环形台阶, 外壳 9的前端滑动套接于 滑动套 2的后端开口内, 使溶媒瓶 3的瓶口与溶质瓶 8的瓶口相对, 中间 通过所迷运针机构连接;
针头 5为两端均有针尖的导通针, 穿入所述运针机构并与其固定连接。 运针机构由滑动架 4、 中间架 6和针架 7所构成, 其中:
滑动架 4由两段直径不等的中空圆柱体构成, 前段直径大于后段直径, 这两段直径不等的中空圆柱体连接处形成环形台阶, 滑动架 4后端外表面 设有凸环 41 , 溶媒瓶 3的瓶口与滑动架 4前端内壁紧配合并被限位在其环 形台阶内侧 , 滑动架 4后端外表面与中间架 6前端内表面滑动配合套接; 中间架 6为中空圓柱体, 其内表面上设有与滑动架 4后端外表面的凸 环 41配合的环形凹槽 61 , 中间架 6的后端与针架 7的封闭端同轴接触; 针架 7为中空圓柱体, 其前端封闭, 中心开孔, 针头 5自开孔中穿过, 并与针架. 7固定连接, 针架 7的后端与溶质瓶 8的瓶口滑动配合套接, 针 架 7的后端内壁上设有卡爪 71 , 当溶质瓶 8的瓶口从针架 7的后端进入到 达其封闭端时, 卡爪 71卡住溶质瓶 8的瓶口后沿。
推拉杆机构由一级推拉杆 14、 二级推拉杆 13、 手柄 15和紧固套 12构 成, 其中:
一级推拉杆 14为空心圆柱体, 其前端外表面设有凸起的台阶 141 , 紧 固套 12套在台阶 141上, 与外壳 9的后端螺旋连接, 将一级推拉杆同轴固 定于外壳 9的后端, 一级推拉杆 14的前端还紧配合外套一个外径略小于溶 质瓶 8内径的压头 11 , 压头 11的前端中心凸起嵌入溶质瓶 8内的活塞 10 后端, 压头 11还外套一个外径等于或略小于外壳 9内径的定位环 16;
二级推拉杆 13 的横截面为 "十" 字形或 " Y " 字形 (图中为示出), 当然也可以为管型, 滑动套接于一级推拉杆 14内部, 靠近其前端的外侧设 有卡钩 131 , 后端与手柄 15固定连接。
本发明的溶媒前置式无菌混药注射器出厂前在溶媒瓶 3 内按用量预灌 封有液体溶媒(注射用水等), 并预克有一定压力的压缩气体。 在溶质瓶 8 内按用量预灌封有粉针剂或水针剂。 注射器整体处于图 1所示的初始状态, 其运针机构的滑动架 4、 中间架 6和针架 7处于图 7所示的初始位置,滑动 架 4外壁上的凸环 41与中间架 6内壁上的凹槽 61吻合。 溶质瓶 8的瓶口 进入针架 7的后端,但还未完全经过其内壁上的卡爪 71, 针头 5在中间位 置并不使溶媒瓶 3和溶质瓶 8导通。推拉杆机构处于图 10所示的初始状态, 一级推拉杆 14与二级推拉杆 13完全套接, 整体长度最短, 此时卡钩 131 不起作用。
应用本发明较佳实施例的溶媒前置式无菌混药注射器实施注射前, 首 先将注射器的前端向上, 使滑动套 2中的溶媒瓶 3倒立, 然后向后推动滑 动套 2, 使溶媒瓶 2推动运针机构的滑动架 4, 由于滑动架 4上的凸环 41 已经嵌入中间架 6内的凹槽 61 , 进而推动中间架 6 , 又通过中间架 6推动 针架 7后移, 使与针架 7固为一体的针头 5后端首先刺穿溶盾瓶 8的胶塞 (如图 2所示), 此时针架 7的内端抵住溶质瓶 8瓶口, 针架 7内的卡爪 71 卡住瓶口后沿。继续推动滑动套 2 ,直至滑动套 2沿外壳 9外壁滑动到限位 处停止,这时滑动架 4上的凸环 41脱离中间架 6内的凹槽 61 ,滑动架 4的 台阶外侧抵向中间架 6前端(如图 8所示), 此时针头 5的前端刺穿溶媒瓶 3的胶塞实现两瓶导通(如图 3所示), 在溶媒瓶 3内预充气体的压力作用 下, 液体溶媒通过中空针头 5进入溶质瓶 8 内, 与粉针剂溶质混合并将其 溶化。
混药完毕后即可拔去滑动套 2 , 同时带动滑动架 4、 中间架 6—并与外 壳 9脱离, 而针架 7由于其卡爪 71已卡住溶盾瓶 8的瓶口后沿, 不会随同 中间架 6—同与外壳 9脱离, 针头 5的后端也不会从溶质瓶 8的瓶口胶塞 中退出, 此时针头 5的前端完全外露, 再向后拉动推柄 15带动二级推拉杆 13相对于一级推拉杆 14向后滑动, 直至二级推拉杆 13上的卡钩 131卡在 一级推拉杆 14后端(如图 4所示)。再推动推柄 15即可通过二级推拉杆 13 和一级推拉杆 14以及压头 11推动活塞 10排净溶质瓶内的气体, 至此注射 前的准备程序已完成。下一步即可进行注射,将混匀和溶解的药液经针头 5 前端注入人体, 完成整个操作过程。
溶媒瓶 3也可以采用无内压的溶媒瓶。 此时需要提前拉出二级推拉杆 1 3 , 推动手柄 15带动压头 11将活塞 1 0前移。 当上述准备程序进行到如图 3所示的两瓶导通状态时,再向后拉动手柄 15带动活塞 10后移,将溶媒瓶 3中的溶媒液体抽入溶质瓶 8中, 实现混药。
2、 本发明的溶媒另置式无菌混药注射器实施方式
因本发明的溶媒另置式无菌混药注射器与溶媒前置式无菌混药注射器 的技术方案有很多相同之处, 因此借助实施例仅就其与本发明的溶媒前置 式无菌混药注射器不同之处加以详细说明。
请参阅图 12至图 16和图 4、 图 5所示,本发明较佳实施例的溶媒另置 式无菌混药注射器与本发明较佳实施例的溶媒前置式无菌混药注射器相 比, 同样由滑动套 2、 溶媒瓶 3、 溶质瓶 8、 活塞 10、 外壳 9、 针头 5、 运 针机构和推拉杆机构所组成, 其中所不同的是:
内置溶媒瓶 3的滑动套 2并不预先与外壳 9套接(如图 12所示), 而 是放置在包装体 18的溶媒槽 1 中, 注射器的其它部分放置于包装体 18的 注射器槽 20中 (如图 16所示);
运针机构只由一个针架 7构成,省略了滑动架 4和中间架 6 ,外露的针 头 5的前端套有针套 17 (如图 1 3所示)。
本发明较佳实施例的溶媒另置式无菌混药注射器除上述不同点外, 其 各部件的形状、 结构、 尺寸以及配合连接关系均与前述较佳实施例的溶媒 前置式无菌混药注射器相同。
应用本发明较佳实施例的溶媒另置式无菌混药注射器实施注射前, 首 先从包装体 18中取出内置溶媒瓶 3的滑动套 2和注射器的其它部分, 去掉 针头 5上的针套 17 , 将滑动套 2的后端开口套接于外壳 9的前端, 然后使 溶媒瓶 3瓶口向下, 向后推动滑动套 2直至针头 5的前后端针尖分别刺穿 溶媒瓶 3和溶质瓶 8的瓶口胶塞, 后续操作与前述较佳实施例的溶媒前置 式无菌混药注射器完全相同, 不需赘述。
上述较佳实施例的溶媒另置式无菌混药注射器中的滑动套 1也可以省 略, 直接将压力溶媒、瓶 3的瓶口对准针头 5的前端, 向后推动溶媒瓶 3 , 同 样可以完成混药操作, 然后将溶媒瓶 3拔除, 进行排气和注射操作。 同样溶媒瓶 3也可以采用无内压的溶媒瓶, 使用时先拉出二级推拉杆 13 , 推动手柄 15带动压头 11将活塞 10前移, 当两瓶处于导通状态时, 再 向后拉动手柄 15带动活塞 10后移,将溶媒瓶 3中的溶媒液体抽入溶质瓶 8 中, 实现混药, 然后将溶媒瓶 3拔掉, 进行排气和注射操作。
以上所述, 仅是本发明的较佳实施例而已, 并非对本发明作任何形式 上的限制, 虽然本发明已以较佳实施例披露如上, 然而并非用以限定本发 明,任何熟悉本专业的技术人员, 在不脱离本发明技术方案范围内,当可利 用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例,但 凡是未脱离本发明技术方案的内容, 依据本发明的技术实质对以上实施例 所作的任何简单修改、 等同变化与修饰, 均仍属于本发明技术方案的范围 内。 工业应用性
本发明的溶媒前置式无菌混药注射器和溶媒另置式无菌混药注射器完 全避免了现有医用注射器存在的缺陷, 与现有技术相比, 其至少具有下列 优点和有益效果:
1、本发明的溶媒前置式无菌混药注射器集溶媒、溶质和注射器为一体, 大大简化了注射前的混药加药操作程序, 缩短了注射前的准备时间, 这对 于急救注射非常重要。
2、 本发明的溶媒另置式无菌混药注射器虽然溶媒瓶另置, 但也集溶质 和注射器为一体, 同样可以简化注射前的混药加药操作程序, 缩短注射前 的准备时间。
3、 本发明的溶媒前置式无菌混药注射器和溶媒另置式无菌混药注射器 携带方便, 操作简单, 不仅适合于医院临床使用, 更适合于野外、 战地和 移动条件(如行驶中的车辆、 航行中的飞机和舰船)下使用和自我救护。
3、 本发明的溶媒前置式无菌混药注射器和溶媒另置式无菌混药注射器 与现有预灌封注射器相比, 简化了运针机构的结构, 特别是其针头既作为 混药导通针头, 又作为注射针头使用, 制造成本也相对降低, 且与产品所 能达到的功效及使用实用性相比较更是物超所值。
4、 本发明的溶娱前置式无菌混药注射器和溶媒另置式无菌混药注射器 由于采用了两级推拉杆的结构设计, 既能显著减小整个装置的总长度和体 积, 有利于包装, 又能满足活塞的最大行程, 保证注射时将药液推净。
5、 本发明的溶媒另置式无菌混药注射器由于将溶媒瓶另行放置, 只在 混药时才需要将其与注射器连接, 且其运针机构只采用一个针架, 进一步 简化了结构, 缩短了整体长度, 更加有利于包装和携带。
6、本发明的溶媒前置式无菌混药注射器和溶媒另置式无菌混药注射器 不仅使用方便, 不需烦杂的手续, 而且结构成形的加工更是简便, 符合成 本效益原则, 而确实具有产业上的利用价值, 特别适于相关业界广泛推广 使用。
7、 本发明在结构设计、 使用的实用性及成本效益上, 确实完全符合产 业发展所需, 并且所披露的结构是前所未有的创新设计, 在申请前既未见 于任何刊物, 更未见有相同的结构特征公知、 公用在先, 且市面上亦未见 有类似的产品, 即在同类产品中均未见有类似的结构设计公开发表或使用, 而确实具有新颖性。 .
8、 本发明的结构确比现有的预灌封注射器更具技术进步性, 且其独特 的结构特征及功能亦远非现有的预灌封注射器所可比拟, 并具有增进的多 项功效, 而确实具有创造性。
9、 本案申请人是实际生产制造医用注射器的公司, 发展此类产品巳有 十数年的经验, 对于现有的预灌封注射器结构所存在的问题及缺陷相当了 解, 而本发明即是根据上述缺陷研究开发而创设的, 完全能够达到预期的 目的及功效, 而确实具有实用性。
综上所述, 本发明特殊结构的溶媒前置式无菌混药注射器和溶媒另置 式无菌混药注射器, 使用简单容易, 运输、 携带方便。 其具有上述诸多的 优点及实用价值, 并在同类产品中未见有类似的结构设计公开发表或使用 而确属创新, 其不论在产品结构或功能上皆有较大的改进, 在技术上有较 大的进步, 并产生了好用及实用的效果, 而具有广泛的产业利用价值, 诚 为一新颖、 进步、 实用的新设计。
