Transfusion bag for accommodating sodium bicarbonate injection, and production method for transfusion bag

Abstract

The invention discloses a low-cost transfusion bag for accommodating sodium bicarbonate injection and a production method for the transfusion bag. The transfusion bag comprises a plastic inner bag for accommodating the sodium bicarbonate injection, and a gas stopping plastic outer bag; and the plastic inner bag is arranged in the gas stopping plastic outer bag. The transfusion bag for the accommodating sodium bicarbonate injection is formed by sleeving the gas stopping plastic outer bag outside the plastic inner bag, and carbon dioxide gas which is produced by hydrolysis of the sodium bicarbonate injection is sealed in a sealed environment by the gas stopping plastic outer bag, so that the sodium bicarbonate injection is in a relatively balanced sate, the hydrolysis of the sodium bicarbonate injection is inhibited, the stability of the sodium bicarbonate injection can be guaranteed, the sodium bicarbonate injection can be accommodated in the plastic transfusion bag, and the cost of the transfusion bag for the accommodating the sodium bicarbonate injection can be reduced greatly; and the plastic transfusion bag is convenient to process, store and transport. The low-cost transfusion bag for accommodating the sodium bicarbonate injection is suitable to be popularized and applied in the field of liquid medicine packaging.

Description

technical field [0001] The invention relates to the field of medical liquid packaging, in particular to an infusion bag for containing sodium bicarbonate injection and a production method thereof. Background technique [0002] Because sodium bicarbonate has the effect of regulating water salt, electrolyte and acid-base balance, therefore, sodium bicarbonate injection is widely used, and sodium bicarbonate is a kind of very unstable compound, and sodium bicarbonate injection will Hydrolysis occurs, and then decomposes into sodium carbonate, water and carbon dioxide gas. Once most of the sodium bicarbonate injection is hydrolyzed, the pH value of the sodium bicarbonate injection will change. If the pH value of the sodium bicarbonate injection changes Injected into the human body, it will cause the PH value disorder of the human body fluid, and medical accidents will occur. Therefore, in order to avoid hydrolysis and deterioration of sodium bicarbonate injection during storage...

AI Technical Summary

Problems solved by technology

Existing plastic packaging is generally made of cheap polypropylene material. However, due to the poor gas barrier performance of polypropylene material, sodium bicarbonate injection can generally only be packed in glass bottles, although the gas barrier properties of glass bottles The performance is better, but the manufacturing cost of the glass bottle is high and the processing is difficult. Moreover, during the transportation process, the glass bottle is easily broken by external force, which is inconvenient for storage and transportation.
