Package for container of liquid medicine containing bicarbonate and PH indicator

本发明提供一种含碳酸氢盐药物溶液包装，包括贮藏含碳酸氢盐药物溶液的气体可透性塑料容器和容纳气体可透性塑料容器的气体不透性塑料部件，容纳时在由容器和包装部件限定的空间内已建立了二氧化碳气氛，且该空间还含有pH指示装置，该装置包括盛放含碳酸氢盐液体(与药物溶液类似)和具有随所述液体pH变化而经历颜色变化性能的pH指示剂的气体可透性塑料盒。就这种包装而言，由于延长贮藏期或像外部包装部件上有针孔影响的麻烦，药物溶液的pH变化和连带的老化很容易用肉眼查明。 The invention provides a bicarbonate-containing medical solution package comprising a gas-permeable plastic container holding a bicarbonate-containing medical solution and a gas-impermeable plastic packaging member accommodating the gas-permeable plastic container, with a carbon dioxide atmosphere having been established in a space defined by the container and packaging member and the space containing a pH indicating device comprising a gas-permeable plastic packet containing a bicarbonate-containing fluid (similar to the medical solution) and a pH-indicator having the property to undergo a change in color in response to a change in pH of the fluid. With this package, the change in pH and consequent aging of the medical solution due to prolonged storage or a trouble such as the incidence of a pinhole in the outer packaging member can be easily ascertained by the naked eye.
