Water sterilization system

Abstract

The invention discloses a water sterilization system which comprises a filter cartridge and a filter cartridge cover, the filter cartridge cover is detachably arranged on the filter cartridge, a filter element shell is arranged in the filter cartridge, a top water permeable membrane is arranged at the top of the filter element shell, a bottom water permeable membrane is arranged at the bottom of the filter element shell, and a sterilization filter element is arranged in the filter element shell. A water inlet groove and a water outlet groove are formed in the filter cartridge cover, the waterinlet groove is connected with a water inlet pipe, the water outlet groove is connected with a water outlet pipe, a filter shell sealing rubber ring is arranged on the lower side of the end, away fromthe water inlet pipe, of the water inlet groove, and the bottom of the filter shell sealing rubber ring makes close contact with the top permeable membrane; a water inlet is arranged in the center ofthe filter shell sealing rubber ring, a water outlet is formed in the bottom of the bottom permeable membrane. The water sterilization system has the advantages that the occupied area is small, and pipelines do not need to be changed during installation; the system can be mounted and used immediately, can be detected and qualified at any time, and can meet the mounting requirements of various types of dental chairs, full-automatic endoscope cleaning and disinfecting machines, manual endoscope cleaning and disinfecting tanks, various waterways and narrow spaces.

Description

technical field [0001] The invention relates to the technical field of sterilization and disinfection, in particular to a water sterilization system. Background technique [0002] It has been proved that the pollution of diagnosis and treatment water and waterways in comprehensive oral treatment units is one of the important ways to cause oral cross-infection. It is considered to be the most effective way to control biological Membrane formation, method for preventing contamination of medical water and waterways. [0003] Reasons for the pollution of the diagnosis and treatment water and waterways of the oral comprehensive treatment unit: [0004] 1. The lumen of the waterway is narrow (2-4mm), the water flow is slow, and it is easy to form biofilm. [0005] 2. The anti-suckback device fails, and a large amount of pollutants are sucked back into the pipeline. [0006] 3. The waterway is heated, and when the water temperature is ≥ 20°C, the bacterial reproduction will be a...

Problems solved by technology

[0012] 4. The water source is tap water, which complies with the GB5749-2006 standard, and the colony is always 100cfu / ml, which is far from the 10cfu / 100ml required for the final rinse water. Therefore, tap water is used as the final rinse water for endoscopes. does not match the requirements

[0013] 5. When the faucet is in contact with the air, new biofilm will be generated, and the biofilm will crawl to the inside of the pipe, resulting in secondary pollution of the water by the biofilm

[0014] 6. The upstream filter of the endoscope decontamination equipment only intercepts large-scale microorganisms, has no sterilization and virus killing functions, and cannot be replaced in time

[0019] 3. The determination of Pseudomonas aeruginosa shall refer to GB15979-2002 "Hygienic Standards for Disposable Sanitary Products", and shall not be detected

[0020] 4. The determination of Legionella shall refer to DB31 / 405-2012 "Hygienic Requirements for the Operation of Air Conditioning and Ventilation Systems in Public Places", and shall not be detected
