Description

Portable electronic endoscope heater

Technical Field

Background

The electronic endoscope is an important examination for ear, nose, throat, head and neck surgery, including electronic laryngoscopes, electronic nasoscope, electronic otoscope, etc., and is an important examination means for diagnosing ear, nose, throat, head and neck surgery diseases. In the inspection process, the front end of the endoscope is heated by hot air blown by a fixed hot air blower at present, and then the endoscope is put into the nose and the ear of a patient for inspection, so that the problem that the cool endoscope generates fog after encountering a warm human body and then blurs a lens to influence the observation is avoided. However, the current heating means before inspection only have a fixed hot air blower, and no portable equipment. In clinical work, many times, patients cannot go to a laryngoscope room to accept examination (such as emergency consultation), and a doctor is required to use a mobile light source to cooperate with a hard tube endoscope to carry out examination, so that sight obstruction caused by fog cannot be avoided, and judgment results are affected. Especially in winter when the temperature is lower, fog can lead to the visual field to be unable to expose completely, and doctor often need to look for heat source such as hot water heating lens temporarily, not only can lead to the lens pollution, can also delay the state of illness because of the time delay. In addition, the condition that the mobile light source is temporarily powered off easily occurs during the inspection, thereby the inspection timing is falsified. Therefore, it is of great importance to design a portable electronic endoscope heater with a charging function.
