Description

A kind of sodium bicarbonate injection flexible package

Technical field

This utility model relates to technical field of medicine packaging, more particularly, and particularly a kind of sodium bicarbonate injection flexible package.

Background technology

Sodium bicarbonate (Sodium Bicarbonate) is commonly called as " sodium bicarbonate ", is white fine crystals, and the dissolubility in water is less than sodium carbonate.Sodium bicarbonate solid decomposes generation sodium carbonate, carbon dioxide and water gradually in beginning more than 50 ℃, decomposes fully in the time of 270 ℃.Sodium bicarbonate is in highly basic and the weak acid and the acid salt of back generation, presents alkalescence when water-soluble.

In medical field, sodium bicarbonate injection is usually used in treating metabolic acidosis, alkalized urine, as antacid, the symptom that the treatment hyperchlorhydria causes etc.Be alkalescence behind the molten water of sodium bicarbonate, easily be decomposed into sodium carbonate, carbon dioxide and water in storage process, if the sodium bicarbonate in the aqueous solution decomposes, its pH value then can change, if after being expelled to human body, then can cause the disorder of pH value in the human body body.

The branch of sodium bicarbonate aqueous solution solve an equation into:

By following formula as can be known, sodium bicarbonate aqueous solution be decomposed into reversible balancing response process, so prevent that one of approach that sodium bicarbonate decomposes is exactly to guarantee that the carbon dioxide that sodium bicarbonate injection decomposites does not run off.Because vial has higher gas barrier property, so in the prior art,, use vial that sodium bicarbonate injection is sealed up for safekeeping, to avoid the loss of carbon dioxide (carbon dioxide that is decomposited by sodium bicarbonate injection) in storage process.

Use vial that sodium bicarbonate is sealed up for safekeeping, though can guarantee to avoid the leakage of carbon dioxide,, because sodium bicarbonate solution is alkalescent medicine, contact with vial for a long time, chemical reaction very easily takes place, cause product visible foreign matters index in storage process defective; The sodium bicarbonate product that vial is sealed up for safekeeping bottle stopper when high temperature sterilize is very easily washed open, causes poorly sealedly, causes that the product P H-number is unusual, microbiological contamination etc.In addition because the manufacturing cost of vial is higher, and bottle is cracked easily, and also depositing of sodium bicarbonate injection proposed higher requirement (avoiding vial that the situation of fragmentation takes place owing to reasons such as collisions).

In sum, how to reduce sodium bicarbonate injection in the decomposition of producing and depositing in the process, become those skilled in the art's problem demanding prompt solution.
