Multifunctional visual laryngoscope

Abstract

The invention discloses a multifunctional visual laryngoscope. When the multifunctional visual laryngoscope is specifically used, the stretch and contraction of a visual kit can be achieved by controlling a driving mechanism, and the image exposure needs of different patients or different exposed views can be accordingly met; when secretions block or cover the visual kit to affect clear display ofthe exposed views, a flushing combination and an attraction combination can be controlled to be started, and after flushing liquid flushes the visual kit, the flushing liquid is taken away through aliquid suction port, thereby fundamentally and rapidly flushing and clearing away the secretions on the visual kit, so that the visual kit keeps clear; in addition, through liquid flushing and liquidpenetrating through a body, the heat generated by the visual kit can be taken away, and a water cooling effect can be accordingly exerted, thereby effectively solving the problem of the temperature influence on the visual kit, and ensuring the clear display of a display screen. The multifunctional visual laryngoscope has the advantages that the structure is simple, the layout is reasonable, functions are diverse, and the use is safe and convenient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional video laryngoscope. Background technique [0002] Due to the deep position of the larynx and its complicated physiological structure, it cannot be directly seen. In medical examination of the larynx, a laryngoscope is often needed. Laryngoscopy can provide a detailed understanding of the abnormality of the laryngeal structure, clarify the location and scope of the lesion, and perform a biopsy of the lesion if necessary. With the development of modern medicine and technology, video laryngoscopes with monitors have been more widely used because they can show the local anatomy of the throat more clearly. The emergence of video laryngoscope has greatly reduced the probability of difficult glottis exposure, improved the success rate of tracheal intubation, reduced airway damage and mortality related to difficult airway, and demonstrated the impact of sci...

Problems solved by technology

[0003] However, the laryngoscope of the prior art has the following disadvantages when checking the larynx: because the video laryngoscope transmits and enlarges the image to the display through the camera, it is easily affected by the temperature difference of the respiratory tract and airway secretions, etc., causing the front end of the camera to The surface forms a condensation film or is covered by secretions, reducing the visibility of the larynx, thereby affecting the efficiency of intubation and the success rate of rescue

[0005] However, the visual laryngoscope with oxygen channel of the above-mentioned technical solution has: the viscosity of laryngeal secretions is strong, and after the lens contacts the secretions or is covered by the secretions, it is difficult to remove them by jet airflow, and the throat It belongs to very important tissues and organs of the human body. In order to avoid damage, it is not suitable for spraying large airflows. Therefore, this solution cannot effectively improve the clarity of the exposed field of view; at the same time, simply selecting LED lights to reduce the temperature impact on the lens cannot Fundamentally control the heating of the lighting lamp, that is, the problem of the temperature influence on the lens cannot be fully solved
