Respiratory support device disinfection device and disinfection method

Abstract

The invention discloses a respiratory support device disinfection device comprising an internal gas way of the respiratory support device, and a one-way on-off valve, an ozone module, a turbine, a temperature sensor, an ozone concentration sensor, a two-way on-off valve, an emergency gas vent and a heating unit which are arranged in the internal gas way of the respiratory support device. The invention also discloses a respiratory support device disinfection method. Compared with the prior art, the respiratory support device disinfection device and disinfection method have better disinfection effect, less risk and better user experience.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a disinfection device and a disinfection method for respiratory support equipment. Background technique [0002] In order to prevent bacteria in the airway of respiratory support equipment, such as household respiratory support equipment, from causing user infection, respiratory support equipment must be disinfected regularly. [0003] Existing respiratory support equipment with disinfection function all have built-in ozone modules and are sterilized by ozone. The user chooses to disinfect manually according to their own use conditions. In order to ensure the disinfection effect during disinfection, it is necessary to manually short-circuit the air outlet and air inlet of the respiratory support equipment to achieve the purpose of disinfection. Ozone is harmful to the human body and needs to be completed after disinfection. Finally, the ozone in the airway inside the...

Problems solved by technology

[0004] However, the existing respiratory support equipment with disinfection function has the following deficiencies: First, ozone is harmful to the human body. If the respiratory support equipment breaks down and causes ozone to be generated during normal use by the user, it will cause harm to the user's human body, and with the ozone module use, its ability to generate ozone will gradually decline, if the ozone concentration does not reach the required concentration (generally 60mg / m 3 ), the purpose of killing the bacteria inside the respiratory support equipment will not be achieved

Thereby lack the monitoring to ozone concentration and corresponding emergency treatment; The 2nd, generally need more than 20 minutes to get rid of the ozone in respiratory support equipment interior airway after disinfection, and ozone is discharged into the indoor where user is located, causes the user's breathing environment to be damaged. pollution, and if the user enters the disinfection mode by mistake, the user cannot directly use the respiratory support equipment after exiting the disinfection mode. In order to prevent ozone from being inhaled by the user, it is necessary to wait for the respiratory support equipment to remove ozone according to the set time before using it

Therefore, the long waiting time affects the respiratory support function of the user's emergency use of the respiratory support equipment and the user's respiratory environment is poor; the third is that the user needs to manually disinfect, and the air outlet and the air inlet are shorted together, which is cumbersome to operate

As a result, the user experience is poor
