药用丁基胶塞资料

药用丁基胶塞的使用安全性药用丁基胶塞的生产背景丁基橡胶瓶塞的内在洁净度、化学稳定性、气密性、生物性能都很好，但是因配方复杂及所加原材料浓度梯度的关系，与一些分子活性比较强的药物封装后，被药物吸收、吸附、浸出、渗透，产生了胶塞与药物的相容性问题，比较突出的是部分头孢菌素类、部分大输液类、以及较多中药注射液制剂等。

所以通过选用一种惰性柔软涂层，覆盖在胶塞表面，隔离药品与橡胶瓶塞的直接接触，这样可以明显改善与药物的相容性。

国家至2004年底前所有药用胶塞(包括输液、口服液等各剂型用胶塞)一律停止使用普通天然胶塞;所有药厂的药品橡胶塞都要使用丁基胶塞。

药品是一种特殊的商品, 其药效与质量直接关系到人身健康和安全, 药品包装的材料与结构形式, 尤其是直接接触药品的包装材料, 对保证药品稳定性起决定性作用。

不适宜的包装材料可引起活性药物成分的渗出、吸附, 甚至发生化学反应, 导致药品失效, 有时还会产生严重的毒副作用。

因此, 药包材的选择是否合适, 是评价药品质量的一项重要指标，丁基胶塞具有吸湿率低, 化学性好, 气密性好, 无生理毒副作用等显著特点, 特别适宜于用作药品密封。

因此天然胶塞已列入被淘汰之列, 而用丁基胶塞取代。

丁基橡胶是由异丁烯和少量异戊二烯(≤3 %)在超低温(- 95 ℃) 条件下聚合而成的共聚物[ 3] ,为白色或暗灰色透明性弹体,其结构式可用下列通式表示:丁基橡胶是气密性最好的橡胶, 其气体透过率约为天然橡胶的1 /20 , 丁基橡胶的耐热性、耐候性和耐臭氧氧化性都很突出。

最高使用温度可达200 ℃, 能长时间暴露于阳光和空气中而不易损坏。

丁基橡胶耐化学腐蚀性好, 耐酸、碱和极性溶剂。

此外, 丁基橡胶的电绝缘性和耐电晕性能比一般合成橡胶好。

耐水性能优异, 水渗透率极低。

减震性能好, 在- 30 ～50 ℃具有良好的减震性能。

在玻璃化温度(- 37 ℃) 时仍具有屈挠性。

丁基橡胶的缺点是硫化速度很慢, 需要高温或长时间硫化, 自黏性和互黏性差, 与其它橡胶的相容性差, 难以并用[ 4] 。

药用丁基胶塞质量标准[指南]

药用丁基胶塞质量标准[指南]药用丁基胶塞质量标准药用氯化丁基橡胶塞标准(试行) YBB 00042002本标准适用于直接与注射剂接触的氯化丁基橡胶塞。

橡胶培训教材

橡胶加工工艺培训教材橡胶，同塑料、纤维并称为三大合成材料，是唯一具有高度伸缩性与极好弹性的高聚物。

橡胶的独特加工工艺是通过“硫化”将线型高分子交联成三维网状高分子量聚合物，即由所谓的原料橡胶转变为硫化橡胶，前者一般上称为生橡胶或生胶，而后者叫做橡胶或熟胶。

橡胶的最大特征是弹性模量非常小，仅为2-4Mpa，约为钢铁的1/3000，而伸长率则高达钢铁的300倍；同塑料相比，伸长率虽接近，但模量只有其1/30。

橡胶的拉伸强度约为5-35 Mpa，破坏时的伸长率可达100-800%。

在350%的范围内伸缩，回弹率能达到85%以上，即永久变形在15%以内。

橡胶最宝贵的性能是在-60至+130℃的广泛温度范围内均能保持正常的弹性。

橡胶以及弹性体另一大特征，是它具有相当好的耐气透性以及耐各种化学介质和电绝缘的性能。

某些特种合成橡胶更具备良好的耐油性及耐温性，能抵抗脂肪油、润滑油、液压油、燃料油以及溶剂油的溶胀；耐寒可低到-60至-80℃，耐热可高到180至350℃。

橡胶还耐各种屈挠弯曲变形，因为滞后损失小，往复20万次以上仍无裂口现象。

橡胶第三特征在于它能与多种材料物质并用、共混、复合，由此进行改性，以得到良好的综合性能。

一，生胶原材料、配合剂1.天然橡胶(NR)天然橡胶是从天然植物中获取的以异戊二烯为主要成分和天然高分子化合物。

在世界上，含橡胶的植物，包括乔木、灌木、藤本及草本等科在内，多达800余种。

而品质好，有经济价值的、现今大量种植发展的只有三叶橡胶树一种。

天然橡胶根据制作工艺不同分为烟片胶和风干胶。

三叶橡胶树上流下的白色乳浆，经凝固，压片，干燥而得。

用烟熏干燥的称为烟片胶，不经烟熏，加入催干剂用空气干燥而成的称为风干胶。

产量上，烟片胶占天然橡胶产量的80%以上（其中烟片3号胶又占50-80%）。

天然橡胶的基本性能包括：（1）生胶及配合橡胶的机械强度均很高；（2）具有独特的粘弹性，分子量大，门尼粘度高，需经塑炼软化之后方能使用；（3）无极性化学分子，在润滑油、液压油、燃料油及溶剂油中极易膨润溶胀：（4）滞后损失小，能耐多次屈挠弯曲变形：（5）橡胶分子主链上有不饱和双键，容易用常规简单的硫磺硫化体系硫化，但硫化的橡胶也易发生老化；（6）生产多限于东南亚等热带、亚热带地区，产量受品种、植产胶周期、气候以及各种自然灾害的影响很大。

丁基胶塞的穿刺部位及穿刺方法

一、正确的穿刺部位及穿刺方法（请参照下图）
1．要在橡胶塞上指示的穿刺穿刺部位进行穿刺。

2．IN为加药时进针部位：OUT为输液时进针部位（见图示）
3．穿刺方法要得当，应使针头垂直刺入橡胶塞的OUT或IN处。

医用橡胶塞要求很严格，其特性可分为：
1．化学特性：材质、溶出物、吸附、与药液的反应等。

2．物理特性：抗剥落性、穿刺性、密闭性、微粒子的发生等。

选定、设计符合所有要求的橡胶塞，在技术上是相当困难的。

通常，为提高橡胶塞自身的密闭性，将橡胶塞的形状设计成可承受容器口部边缘压缩力的结构，但用注射针（不锈钢针头）穿刺橡胶塞时，橡胶因内压力而挤入针头内部，进而很容易被针尖的横倾面切下形成碎屑（见图1）。

图1发生掉屑的主要原因
该部分橡胶被横倾部切下
使用不锈钢针头穿刺橡胶塞时，一般有以下几种可能（见图2）
①针尖横倾面朝上斜着穿刺②垂直穿刺③针尖横倾面朝下斜着穿刺
有试验文献报导，穿刺部位和穿刺方法的不同，导致掉屑发生的数量也不同。

为防止橡胶塞穿在穿刺进发生掉屑，我们建议：
一、要在橡胶塞穿刺部位进行穿刺
在穿刺部位以外插针时，由于厚度较厚，会使掉屑数量增多，而在穿刺部位插针，则厚度较薄，可大大减少碎屑发生率。

二、穿刺方法要得当
斜着穿刺时，碎屑发生的数量较多，这是由于针尖横倾面与橡胶塞呈锐角，橡胶较易被切下，而垂直穿刺效果最好，斜着刺入时如能将针尖横倾面朝下，则碎屑发生也会减少。

三、最好使用侧口树脂针
目前，市场上输液器品种较多，但大多为不锈钢针，在使用时较易发生碎屑。

有一
种侧开口树脂针头，可避免在穿刺时发生掉屑，效果很好。

橡胶塞产品，使我们的产品日臻完美。

(2)热原的产生与微生物的存在密切相关,因此对微生物的有效控制是至关重要的。

(3)注射用水水质的污染包括外源性污染和内源性污染。

外源性污染包括进料水、排气口或由于系统存在泄漏而与外界污染接触所致;内源性污染是系统运行中产生的,可能是水处理设备单元贮存与分配系统的设计、选材、安装、运行、维护和使用不当产生利于微生物生存、繁殖的生物膜所致。

(4)注射用水系统的水质保证体系包括硬件、软件和人员。

关键词丁基胶塞生产车间设计1 概述医用瓶塞是瓶装药物(如抗生素、冻干粉针、大输液、口服液)的主要封口件和导出件,由于它和药物直接或间接接触,因此必须满足药物对其的要求,不得与药物通过吸附、吸收、渗透和浸提等方式交互作用,从而影响或污染药物。

从生物角度要求,瓶塞必须无致热、无毒性;从卫生角度着眼,瓶塞必须洁净无菌;从药品的贮存来讲,瓶塞必须有良好的化学稳定性、气密性、耐老化性和低析出性;从瓶塞与瓶的配合考虑,瓶塞要有良好的弹性及物理机械性能;从临床使用考虑,瓶塞必须保证适宜的针刺力和低的落屑;与此同时,瓶塞的结构还必须满足药品生产封装的要求。

8.2. 穿刺落屑:选择与胶塞配套的500ml（口径26mm或28mm ）20个，瓶内加1/2公称容量水，取待检品10个，已知穿刺落屑数的胶塞10个，分别装到瓶上，盖上铝塑组合盖，用手动封口机封口，放入高压蒸汽消毒器中，在121℃±2℃下保持30分钟，取出冷却至室温，分两排放置，第一排为被测胶塞，第二排为已知胶塞。

用丙酮或其它适当的有机溶剂擦拭金属穿刺针，然后将其浸在蒸馏水中。

手持穿刺针，垂直穿刺第一排第一个被刺胶塞上的标记部位，剌入后，晃动玻璃瓶数秒后，拔出穿刺针。

按上述步骤穿刺第二排第一个已知穿刺落屑数胶塞。

以此类推，按先被胶塞再已知穿刺落屑数胶塞的顺序，交替垂直穿刺胶塞上的标记部位，直至所有胶塞被穿刺一次。

将第一排瓶中水全部通过一张滤纸过滤，确保瓶中不残留落屑，在人眼距离滤纸25厘米的位置，用肉眼观察滤纸上的落屑数（相当于50μm以上的颗粒），必要时可通过显微镜进一步证实落屑大小和数量。

对已知穿刺落屑数的胶塞同法计数。

结果显示：分别记录两排瓶子的可见落屑数（即每十针的落屑总数）。

若已知穿刺落屑胶塞的结果与先已知的结果具有一致性，则应判被测胶塞测得结果有效。

反之，则无效。

在穿刺过程中，若有两个以上（含两个）胶塞在穿刺过程中被推入瓶中，则判该项不合格，若10个被测胶塞中有一个被推入瓶中，则另取10个胶塞重新试验，不得有胶塞被推入瓶中。

天然橡胶塞是从天然橡胶中提取出来的，由于含有对人体有害的异性蛋白等成分，密封性能也不好，因此会影响药品的疗效，从2005年起，药用丁基橡胶瓶塞作为Ⅰ类药用包材开始有计划强制性地取代天然橡胶瓶塞［1～4］。

这一转变给大容量注射剂生产企业带来了一定的挑战，在产品质量控制方面出现了新的不可控因素。

药用丁基胶塞的处理工艺设计

药用丁基胶塞的处理工艺设计摘要】目的探索药用丁基胶塞处理过程中参数控制与水分的关系，从而确定最佳参数的处理工艺。

方法通过处理不同数量的药用丁基胶塞和改变处理的参数〔干燥时间，F0值(标准灭菌时间)〕，用干燥失重法检测经处理后的药用丁基橡胶塞水分残留量，统计分析各参数条件下的用丁基胶塞水分残留量。

结果当F0值为15，干燥时间为60分钟时，胶塞的处理数量越大处理后的水分残留值越大；当胶塞的处理数量一定，F0值为15,干燥时间越长水分残留值越小；当胶塞的处理数量一定，干燥时间在60分钟时，F0值越大水分残留值越大。

结论经综合分析选用F0值为15，干燥时间为60分钟的处理工艺既符合生产工艺要求又节约能源。
