Abstract

An infusion bag is made from flexible plastic. The infusion bag includes a bag body, a neck portion provided on the upper part of the bag body and a base portion provided on the lower part of the bag body. The cross section of the bag body is shuttle-shaped and leading ribs (1) are provided on the shoulder of the bag and the connection parts of the base portion and the bag body.

Description

技术领域： Technical field:
本发明是一种输液袋。  The present invention is an infusion bag.
背景技术： Background technique:
目前国内时常使用的袋装输液容器， 主要有玻璃袋和塑料袋， 其 中塑料输液袋在现代治疗过程中被广泛的应用。 其特点在于造价便 宜，使用方便。并朝着密封自排液的方向发展。专利号为 200420036457 的专利公布了一种软质塑料输液袋，其特点在于通过袋体两侧的导向 筋来实现袋体的定向吸瘪，但这种设计并不完善， 没有从根本上解决 自排液彻底的问题。  At present, bagged infusion containers commonly used in China mainly include glass bags and plastic bags, among which plastic infusion bags are widely used in modern treatment processes. It is characterized by low cost and easy to use. And in the direction of sealing self-discharge. Patent No. 200420036457 discloses a soft plastic infusion bag, which is characterized in that the directional suction of the bag body is realized by the guide ribs on both sides of the bag body, but the design is not perfect, and the self-solving is not fundamentally solved. The problem of thorough drainage.
发明内容： Summary of the invention:
本发明的目的是提供一种输液袋，从设计根本上消除袋体在关键 部位的对大气压力的应力使其达到完全定向吸瘪， 从而自排液彻底。  SUMMARY OF THE INVENTION It is an object of the present invention to provide an infusion bag which substantially eliminates the stress on the atmospheric pressure of the bag at a critical portion from the design so as to achieve a fully oriented suction, thereby completely draining the liquid.
本发明的一种优选方案为一种输液袋 , 由软质塑料制成， 包括一 袋身以及设置在该袋身上部的袋颈和设置在该袋身下部的袋底，袋身 横截面为梭形， 在袋肩和袋底与袋身的连接处设有导向筋。  A preferred embodiment of the present invention is an infusion bag made of soft plastic, comprising a bag body and a bag neck disposed on the body of the bag and a bag bottom disposed at a lower portion of the bag body, the bag body cross section being In the shape of a shuttle, a guide rib is provided at the joint of the bag shoulder and the bottom of the bag and the bag body.
本发明的另一种优选方案为该袋身与该袋颈之间设有肩部，该导 向筋设置在该袋肩上为三角形。  Another preferred embodiment of the present invention provides a shoulder between the bag body and the neck of the bag, the guide rib being disposed on the shoulder of the bag as a triangle.
本发明的再一优选方案为该袋身与该袋底之间设有三角形的导 向筋。  According to still another preferred embodiment of the present invention, a triangular guide rib is provided between the bag body and the bottom of the bag.
本发明的最优选方案问该导向筋为线状凹槽，该输液袋是由聚丙 烯软质塑料一体成型。  In a most preferred embodiment of the invention, the guiding rib is a linear groove, and the infusion bag is integrally formed of polypropylene soft plastic.
综上所述， 本发明的输液袋， 改变了袋肩处和袋底与袋身的连接 处的形状，通过导向筋产生的折角效果消除了原来由于圆弧形袋肩产 生的周向应力， 在袋内液体流出后， 袋内压力小于大气压的时候袋身 局部更容易产生形变。此时袋身应力集中到了袋肩的两个三角型导向 筋上， 达到非形变区域最小化的效果。 而横截面为梭形的袋身使整体 的应力更集中于袋体两侧的尖端，在其椭圆弧面的应力同时达到了最 小使得在受到相同大气压力的情况下更容易产生形变。 In summary, the infusion bag of the present invention changes the shape of the joint between the shoulder of the bag and the bottom of the bag and the bag body, and the angle effect generated by the guide rib eliminates the circumferential stress originally generated by the arc-shaped shoulder. After the liquid in the bag flows out, the body of the bag is more susceptible to deformation when the pressure inside the bag is less than atmospheric pressure. At this time, the stress of the bag body is concentrated on the two triangular guide ribs of the bag shoulder, and the effect of minimizing the non-deformation region is achieved. a cross-section of a fusiform body makes the whole The stress is more concentrated on the tips on both sides of the bag body, and the stress on the elliptical arc surface is simultaneously minimized so that deformation is more likely to occur under the same atmospheric pressure.

图中 1为导向筋。  In the figure, 1 is a guide rib.
具体实施方式： detailed description:
本发明的一种实施方案为，袋身上所设导向筋的宽度为中间部分 宽， 靠近袋子横截面的尖端部分导向筋宽度窄。  One embodiment of the present invention is such that the width of the guide rib provided on the bag body is wide in the middle portion, and the width of the guide rib near the tip end portion of the bag cross section is narrow.
本发明的另一种实施方案为，袋身上所设导向筋的宽度不发生变 化。  Another embodiment of the invention is such that the width of the guide ribs provided on the bag does not change.
