Abstract

一种自吸塑料输液瓶，属于医药包装容器，由瓶体、瓶底、瓶肩和瓶口所组成，在瓶底制有吊环连接凸嘴，其主要特点是所述的瓶体是椭圆柱形瓶体1，所述的瓶肩是椭圆锥形瓶肩4。采用塑料制造的椭圆柱形瓶体结合椭圆锥形瓶肩的输液药瓶，在灌满液体时，瓶体被内压液体支撑，或瓶的内、外大气压力平衡时，保持立体形状，但当瓶内液体减少，失去液体对瓶壁的支撑力后，塑料瓶在外界大气压力的作用下会自动内陷下瘪，特别是椭圆锥形的瓶肩有利于液体流出，从而在输液时不需要在瓶口塞中插进气针头，达到自吸输液目的，克服了进气针头从空气中向瓶内带入病菌和污染物的缺陷，并且减少了操作麻烦。

Description

自吸塑料输液瓶
                       技术领域
本实用新型涉及输液瓶，特别是涉及塑料输液瓶，属于医药包装容器。
                       背景技术
将注射药液稀释在葡萄糖盐水等溶液中，通过静脉滴注，是一种常用的给药方法，具有吸收完全，作用速度快等特点。已有用于包装葡萄糖盐水的容器按照制造材料不同可分为两类，一类是玻璃瓶，另一类是塑料瓶或者塑料袋。玻璃瓶因为硬度高、刚性好，一般制成圆柱型瓶体，而塑料瓶却为了达到有较好的刚性强度，通常制成方柱型瓶体。圆柱型的玻璃瓶和方柱型的塑料瓶在输液时，一方面瓶内的液体通过输液器流出，而另一方面又必须不断地向瓶内进入空气，所以，在瓶口塞中插进气针头。因此，已有塑料输液瓶存在的缺点是不能自吸，空气进入瓶内会带入病菌和污染物，而且操作麻烦。
                       发明内容
本实用新型为了克服已有技术的缺陷，提供一种在输液时瓶口瓶塞中不插进气针头，随着瓶内液体输出，塑料输液瓶会自行收瘪的自吸塑料输液瓶，其技术方案是：由瓶体、瓶底、瓶肩和瓶口所组成，在瓶底制有吊环连接凸咀，其特征在于所述的瓶体是椭圆柱形瓶体，所述的瓶肩是椭圆锥形瓶肩。采用塑料制造的椭圆柱形瓶体结合椭圆锥形瓶肩的输液药瓶，在灌满液体时，瓶体被内压液体支撑，或瓶的内、外压力平衡时(指空瓶)，保持立体形状，但当瓶内液体减少，失去液体对瓶壁的支撑力后，塑料瓶在外界大气压力的作用下会自动内陷下瘪，特别是椭圆锥形的瓶肩，有利于液体流出，从而在输液时不需要在瓶口塞中插进气针头，达到自吸输液目的，克服了进气针头从空气中向瓶内带入病菌和污染物的缺陷，并且减少了操作麻烦，构造的改变，取得意想不到的效果。
                       附图说明
图1是本实用新型自吸塑料输液瓶构造示意图；
图2是自吸塑料输液瓶A向示意图；
图3是自吸塑料输液瓶B向示意图；
图4是自吸塑料输液瓶另一实例形状示意图；
图5是自吸塑料输液瓶C向示意图。
                     具体实施方式
本实用新型公开了一种用于医疗的塑料输液瓶，一个椭圆柱形的瓶体1，椭圆柱形瓶体1下连接瓶底2，瓶底2制有输液吊环的连接凸咀3(在输液时需要将瓶底倒置挂起来)，瓶的顶部是瓶口5，在瓶体与瓶口之间是瓶肩部分，制成椭圆锥形瓶肩4，椭圆锥形瓶肩4下口径大，上口径逐渐收小，输液时输液瓶倒置是瓶口5朝下，而瓶底2朝上，所以椭圆锥形瓶肩4就成为大口径在上而小口径在下，非常有利于瓶内药液输出。以塑料材料制成瓶壁较薄的椭圆锥形瓶肩4和椭圆柱形瓶体1抗外压强度差，所以瓶内液体一旦流失后，在环境大气压的作用下，会自动向内陷瘪。但如果采用已有技术的圆柱形或者方柱形的塑料瓶体，再通过人体肩膀模样的横向水平瓶肩连接瓶口，其抗外压强度和刚度提高，不会产生自动向内陷瘪，只能不断向瓶内进入空气，才能保持压力平衡，再在输液管位差的情况下，完成连续输液。
