Problems solved by technology

[0002] Water for injection is a very common solvent in pharmaceutical production or medical care, and there are strict standards for the production of water for injection. At present, the water for injection produced by ordinary water for injection production methods still contains a small amount of microorganisms, which is not in the absence of bacteria. Bacterial state, general hospitals are also unconditionally equipped with special sterilization equipment to sterilize water for injection, therefore, it cannot be directly used as a solvent for sterilized powder for injection or a diluent for injection or as a flushing agent for endoscopes in various departments. it's inconvenient

Abstract

The invention provides a preparation method of sterile water for injection. The preparation method comprises the following steps of (1) preparing purified water; (2) preparing water for injection by using the purified water; and (3) preparing the sterile water for injection by using the water for injection. The sterile water for injection can meet various testing standards, does not need to be sterilized before use and after use and can be directly used, and therefore, the sterile water for injection is relatively convenient to use.

Description

technical field [0001] The invention relates to the medical field, in particular to a preparation method of sterilized water for injection. Background technique [0002] Water for injection is a very common solvent in pharmaceutical production or medical care, and there are strict standards for the production of water for injection. At present, the water for injection produced by ordinary water for injection production methods still contains a small amount of microorganisms, which is not in the state of innocence. Bacterial state, the general hospital is unconditionally equipped with special sterilization equipment to sterilize water for injection, therefore, it cannot be directly used as a solvent for sterile powder for injection or a diluent for injection or as a flushing agent for endoscopes in various departments. It is very inconvenient. Contents of the invention [0003] The invention proposes a preparation method of sterilized water for injection. The sterilized wa...
