Oral cavity examination appliance

Abstract

An oral examination appliance is disclosed. The oral cavity examination instrument comprises a shell, an OLED light source and a driving device, the OLED light source is provided with at least one light-emitting surface; the shell comprises a hard part and a flexible part, the shell comprises a first surface, and a light-emitting surface of the OLED light source is arranged on one side of the first surface; and the driving device is electrically connected with the OLED light source. According to the oral examination appliance, the OLED is used as a light source, the OLED can deform in use so as to be better attached to the irregular structure in the oral cavity, the position of the light source can be dynamically adjusted in the modes of bending, twisting and the like, and the observation difficulty is greatly reduced; the OLED light source on the oral cavity examination appliance can be lightened in sections, and the non-lightened part can be used as a mirror surface; and the used oral examination appliance can be directly soaked in alcohol for disinfection, can be repeatedly used, and is environment-friendly and convenient.

Description

technical field [0001] The present invention relates to the field of medical appliances. Specifically, it relates to an oral examination appliance with an OLED light source. Background technique [0002] There are many kinds of oral examination instruments, such as tongue depressors, dental mirrors, etc. When doctors use such instruments, doctors need a light source as an auxiliary tool to effectively observe the inside of the patient's oral cavity. During the operation, the doctor either uses a head-mounted light, or holds a flashlight in one hand and places the device in the patient's mouth to be tested with the other hand. For a doctor, such an operation is very inconvenient, requires two hands, or needs to constantly adjust the angle of the head-mounted illuminator for effective observation, which greatly reduces the work efficiency. For patients, the light source used by the doctor is irradiated from outside the oral cavity. Most of the time, it is an LED or other poi...

AI Technical Summary

Problems solved by technology

Patent CN202776247U mentions that OLED is used as a light source in oral mirrors, but this application only integrates OLED as a conventional light source on the part near the mirror at the top of the handle, and the light-emitting area that can be used due to the limitation of the handle is very small. From the given According to the schematic diagram, the luminous area will not exceed 1cm 2

The most important thing is that the OLED light source in this application is not directly integrated on the surface of the handle, and does not take advantage of OLED as a surface light source, and the OLED light source in this design is fixed and cannot be deformed

Finally, from an operational point of view, it is impractical to set the light source at the top of the handle, because in this case the light source will directly shine on the mirror surface at the top, and cannot shine on the part to be observed
