Abstract

The invention discloses a device and a method for preparing sterile water for injection. The device comprises an upper tank body, a first filter device, a lower tank body, a secondary steam tank, a second filter device and a finished product collecting device, wherein raw water enters the upper tank body, then partial impurities are filtered by virtue of the first filter device, steam is formed in the lower tank body, the steam is condensed, then secondary evaporation is carried out by virtue of a secondary evaporation tank, recondensation is carried out, then refined filtration is carried out twice, finally water quality is detected in the finished product collecting device, and after the water quality meets various indexes, a detection tank is communicated with a finished product tank, water is put into the finished product tank, and the water in the finished product tank is subjected to encapsulation and then is subjected to sterilization treatment, so that the sterile water for injection is obtained, and when the water quality is unqualified, the water flows into the upper tank body again, and processing is carried out again until the water quality is qualified. The device and the method which are disclosed by the invention have the advantages that water quality requirement is low, the device is simple in structure and easy to maintain, and the water quality is detected in real time, so that quality and service safety of the sterile water for injection are improved; meanwhile, a preparation process is simple and easy to master, and preparation cost is effectively reduced.

Description

technical field

[0001] The invention relates to the technical field of pharmaceutical processing, in particular to a device for preparing sterilized water for injection and a preparation method thereof. Background technique

[0002] With the development of modern science and technology, the production requirements of water for injection used by pharmaceutical factories, hospitals and scientific research units are constantly increasing, which requires production equipment companies to provide efficient and high-quality equipment to ensure the quality of water for injection, and at the same time The equipment produced can achieve the goals of energy saving and long service life. However, the most widely used in the market is the multi-effect distilled water machine. This kind of equipment has small water production, high energy consumption, short service life, large floor area, unstable water quality, high requirements on raw water quality, and affects production. Efficiency,...
