Description

A pressure steam sterilization B-D vacuum test bag

technical field

The invention specifically relates to a pressure steam sterilization B-D vacuum test bag using microporous ceramics as reusable auxiliary materials.

Background technique

At present, the pressure steam sterilization B-D test vacuum test kit used in the hospital is a product that is strictly required by the national regulations. The first pot of empty pot is tested every day. The purpose is to test whether the vacuum performance of the sterilizer is reliable and the accessories Whether the cold air in the bag can be removed and whether the pressure steam can quickly penetrate the accessories. If the pressure steam sterilization B-D test fails, it means that the removal of cold air from the sterilizer is not complete or the door gasket leaks, resulting in cold air remaining in the sterilizer, which will prevent the sterilization process. The penetration of steam to the items in the sterilizer has a serious impact on the sterilization effect. The current pressure steam sterilization B-D test package uses disposable multi-layer cardboard as an auxiliary material, and the pressure steam sterilization B-D vacuum test chart is sandwiched between the multi-layer cardboard, simulating the standard cloth bag. After the test, once Safe jam disposal, autoclaved B-D vacuum test chart archive.

The number of pre-vacuum pressure steam sterilizers is about 60,000, and the installed capacity is increasing at an annual rate of 3,000. Each pre-vacuum pressure steam sterilizer runs one pot of pressure steam sterilization B-D test per day, 300 working days per year, and consumes about 18 million pressure steam sterilization B-D vacuum test packs per year. Each disposable paper auxiliary material weighs 0.2 kg, and a total of 3,600 tons of paper are consumed throughout the year. Producing 3,600 tons of paper requires 8,000 tons of wood, 360,000 tons of water, and 2.16 million kilowatt-hours of electricity. It consumes a lot of natural and human resources, and has caused serious damage to the environment throughout the year.
