Description

Infection management system and method of surgical tool using ultrapure water and nitrogen}

The present invention relates to a system and method for infection control of surgical instruments using ultrapure water and nitrogen, and more specifically, ultrapure water and nitrogen that can manage infection of surgical instruments using ultrapure water (H ₂ O) and nitrogen (N ₂ ). It relates to an infection management system and method of surgical instruments using.

A dental handpiece is a dental medical device that polishes and removes infected or damaged teeth, and is contaminated with saliva, blood, tooth chips and powder, as well as various pathogenic microorganisms and viruses, etc. in the mouth of a patient during use. In general, contaminants in handpieces such as saliva and blood may contain various disease-causing factors such as AIDS and hepatitis, so contaminated handpieces can cause fatal transmission to other patients as well as doctors and nurses who use them. .

In addition, since the handpiece is not a disposable surgical tool (medical device), the used handpiece must undergo cleaning, disinfection and sterilization in order to prevent transmission to users such as doctors, nurses, and the next patient. .

Conventional methods of washing and disinfecting surgical instruments such as used handpieces include boiling the surgical instruments in boiling water or using a high-temperature, high-pressure autoclave. However, the conventional method has a disadvantage in that it takes too much time to clean and disinfect one surgical tool, and there are problems in that the cleaning and disinfection efficiency is inferior.

This is because the patient's waiting time for treatment is prolonged when considering a large number of patients, and the quality of medical services experienced by the patient is deteriorated, and it may not be possible to clean and disinfect the surgical instruments for a sufficient time for prompt treatment. , Transmission of various disease-causing factors can be caused. In addition, in the case of the handpiece, the above-described problem was remarkable due to the high frequency of use among dental surgical tools.

In addition, the conventional cleaning and disinfection method using high temperature and high pressure not only damages surgical instruments such as handpieces and deteriorates its function, but also remains inside the handpiece even when various disease-causing factors are inactivated through high temperature and high pressure. Since it can be transferred to a patient to help the proliferation of pathogenic microorganisms, an effective cleaning and disinfection method for surgical tools such as handpieces is urgently required.

In recent years, according to such a request, a cleaning and disinfection method using ultraviolet rays and ultrasonic waves has been proposed. However, in the case of low-ultraviolet rays, only the part irradiated with ultraviolet rays was cleaned and disinfected, so the inside of the handpiece was not cleaned and disinfected at all. There were some limitations.
