Loop disinfection and drying device and method for respiratory supporting equipment

Abstract

The invention provides a loop disinfection and drying device and method for respiratory supporting equipment, and realizes the disinfection treatment of internal and external loops. A humidity detection device is arranged, the drying effect is ensured, the possibility of bacterial breeding caused by under drying after disinfection completion is reduced, and the reliability of the loop disinfectionof the respiratory supporting equipment is improved; meanwhile, the mist after disinfection completion is recovered, the air pollution is avoided, and the risk of iatrogenic cross infection is greatly reduced; a temperature detection device is arranged, when the temperature is too high, the alarm is conducted, when the alarm, the occurrence of excessive temperature is prevented, and the fire andother accidents are eliminated; and the disinfection cost can be reduced under the premise of simplifying the operation steps, and the efficiency and effect of the loop disinfection of the respiratorysupporting equipment are greatly improved. The loop disinfection and drying device is simple in operation, high in safety, high in disinfection and drying effect, and high in disinfection success rate.

Description

technical field [0001] The invention relates to the technical field of respiratory support equipment, in particular to a device and method for disinfecting and drying a circuit of respiratory support equipment. Background technique [0002] Respiratory support equipment, as a medical device for the treatment of chronic obstructive pulmonary disease and obstructive sleep apnea hypopnea syndrome, can improve respiratory function by increasing lung ventilation, and has been increasingly used in clinical and family . However, due to the special structure of the internal circuit of the respiratory support equipment and the non-detachable characteristics of the circuit, most hospitals or users currently only sterilize the external circuit when disinfecting the circuit of the respiratory support equipment, and basically do not sterilize the internal circuit. What is worrying is that after long-term or special disease patients use respiratory support equipment for auxiliary treatme...

AI Technical Summary

Problems solved by technology

Although there have been studies on the disinfection of the inner circuit of respiratory support equipment, most of them are complicated to operate, and the disinfection effect and safety are not ideal. There is no monitoring of the temperature and humidity during the disinfection process. risk of bacterial regrowth caused by

[0003] Although there have been researches on the disinfection of the inner circuit of respiratory support equipment, it uses the disinfection characteristics of ozone molecules to realize the disinfection of the inner circuit, and uses disinfectant to disinfect the outer circuit. The operation is complicated, and the main defects are as follows: no drying treatment or poor treatment effect

After the disinfection is completed, the internal and external circuits are not dried, and the possibility of bacterial re-breeding increases

Or there is drying, but the humidity is not detected, and there is a possibility that the drying is not complete

low security

None of the existing disinfection devices detect the pressure or temperature of the pipeline during the disinfection and drying process. When the pipeline is too large or the temperature is too high, there is a risk of pipeline tearing or burning

Or the exhaust gas and mist are forcibly discharged without treatment, which poses a risk of air pollution

[0004] Patent document CN201610551665 discloses a disinfection machine for internal and external circuits of respiratory support equipment. This type of disinfection machine for internal and external circuits of respiratory support equipment has the following disadvantages: after the disinfection is completed, the aerosol is forcibly discharged without treatment, and there is a risk of air pollution; disinfection After the completion, the internal and external circuits are not dried, and the possibility of bacterial re-breeding increases

[0005] Patent document CN201220567276 discloses a disinfection and drying device for medical respiratory support equipment. This kind of disinfection and drying device for medical respiratory support equipment has the following disadvantages: the hose needs to be pushed to the bottom of the respiratory support equipment during disinfection, and the disinfection After the completion, the bottom must be retracted, which is difficult to operate and has a complicated structure; the air pressure is not controlled during the entire disinfection process, and there is a risk of circuit tearing when the air pressure is too high; there is no temperature detection and control during disinfection, and it is difficult to detect and easily Accidents such as fires occur; the humidity is not detected during drying, and the possibility of incomplete drying increases
