Video laryngoscope

Abstract

The invention provides a video laryngoscope, comprising: a lens for inserting into the throat, a handle and a display screen, an LED light-emitting tube, a CMOS camera and its control circuit are arranged in the lens, and a power supply for the lens and the display screen is arranged in the handle The used power supply and power supply circuit, the CMOS camera sends the image it captures to the display screen for display. According to the video laryngoscope of the present invention, by setting a CMOS camera in the lens, and then sending the image captured by the CMOS camera to the display screen through the handle, the video laryngoscope can obtain a higher and clearer image, and through The liquid crystal display can observe the structure of the throat and the whole process of inserting the catheter into the glottis, which improves the efficiency of teaching, examination and operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a video laryngoscope. Background technique [0002] As one of the most widely used medical instruments at present, laryngoscope belongs to the category of medical endoscope series. The laryngoscope has a certain pertinence and particularity, and is mainly used to assist doctors in conveniently observing and diagnosing the human throat. [0003] According to different structures and diagnostic methods, traditional laryngoscopes can be divided into indirect laryngoscopes and direct laryngoscopes. Indirect laryngoscopy uses the principle of mirror reflection to illuminate and reflect the patient's throat through a small round mirror with a handle. This method has the advantages of simplicity, ease of operation, and less pain for the patient. For long patients and infants, it will be difficult to check; indirect laryngoscopy uses a hollow metal or plastic tube with a li...

AI Technical Summary

Problems solved by technology

[0010] 1. The image processing function is simple, and generally only has the basic functions of video observation, which cannot meet the needs of high-end users, and the effect of eliminating lens fogging is poor, which often causes difficulties for intubation observation

[0011] 2. The image definition is not high, limited by volume, cost, development difficulty, etc., low-pixel CMOS / CCD is generally used

[0012] 3. The light source generates a lot of heat, the electromagnetic interference is large, and the system life is short

[0013] 4. The operation is not sensitive, the bending radius is large, the volume and quality are too large, and the user experience is poor

[0014] 5. The service life of the battery is limited, and the cumulative working time is about 200 hours after one charge.
