Medical machine pipeline sterilization device

Abstract

The invention relates to a medical machine pipeline sterilization device which is characterized by comprising two circulation loops in mutual parallel connection, and specifically comprising a sterilization loop, an elimination loop as well as an ozone generator (3), wherein the sterilization loop is used for sterilizing a medical machine (8); the elimination loop is used for eliminating residualgases after sterilization; a first branch pipeline for introducing gases is arranged on the sterilization loop; an ozone decomposer (4) as well as a second branch pipeline for introducing atmosphere and a third branch pipeline for discharging the gases are arranged on the elimination loop; and the ozone generator (3) is arranged on the sterilization loop or the first branch pipeline. Compared withthe prior art, the medical machine pipeline sterilization device has the advantages of being long in sterilization effect lasting, high in ozone utilization rate, applicable to equipment of differentpipeline pressure intensities, convenient in mode switching, and the like.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical machine pipeline disinfection device. Background technique [0002] Medical machines are widely used in medical procedures, such as ventilators, anesthesia machines, and nebulizers to name a few. Among them, the ventilator is an important medical device widely used clinically to prevent and treat respiratory failure, but the pollution of the ventilator pipeline and its accessories can cause ventilator-associated pneumonia. Therefore, the ventilator must be strictly disinfected before and after use to reduce and avoid cross-infection of patients. [0003] At present, disposable medical device products are used clinically for detachable ventilator pipelines, or detachable parts are routinely cleaned and disinfected for repeated use. The conventional disinfection methods mainly include: soaking in chemical disinfectants, fumigation with chemical disinfectants ...

AI Technical Summary

Problems solved by technology

The current technology also uses ozone disinfection methods, such as ventilator disinfection treasure, whose technical feature is to convert the oxygen in the air into ozone and then disinfect the ventilator, but the defects of this technology include: using air as the gas source, it cannot generate a high enough The concentration of ozone cannot maintain the ozone concentration during the continuous disinfection time, resulting in invalid disinfection; the disinfection process is in an open state, that is, the air is converted into ozone by the disinfection treasure, the ozone enters the ventilator, and the exhaust gas of the ventilator is discharged into the environment. The state also causes the ozone concentration to fail to reach the concentration required for disinfection, resulting in ineffective disinfection; the open state of the disinfection process will also cause users to be directly exposed to ozone, which is potentially harmful
