Background
In recent years, the research level of medical sensory control is continuously promoted. The research shows that the medical endoscope is a modern medical instrument which brings great contribution to the improvement of the life quality of human beings, and due to the reasons of the complex structure of the instrument, the characteristics of finished materials and the like, the endoscope is not thoroughly cleaned due to improper washing and disinfecting in the using process, or is not cleaned in time after being polluted, and a biological membrane is easily formed at the polluted part of the endoscope. In addition, after repeated cleaning of the endoscope, the surface of the endoscope is damaged, and a biofilm is easily formed at the damaged portion because of non-smoothness. The biomembrane becomes a huge protective umbrella of bacteria, the bacteria in the biomembrane has strong resistance to disinfectant, antibacterial agent and host immune defense mechanism, and the drug resistance of the bacteria covered in the biomembrane is more than 1000 times stronger than that of planktonic bacteria. For this reason, the medical community has called for the use of disposable medical endoscopes to avoid the risk of viral cross-infection to patients due to the use of endoscopes.
However, the existing disposable medical endoscope is affected by human factors in the actual use process, and can be frequently reused, and even applied to different patients, so that the cross infection phenomenon is serious. For this reason, a disposable medical endoscope having a timer has been developed, which prevents cross-infection by controlling the use time of the disposable medical endoscope. However, such endoscopes have a serious drawback in that, if the endoscope is used for a predetermined usable period of time for another patient or even for a plurality of patients, it is still usable normally, and there is no way to follow up the investigation of the resulting cross-infection event.
