Reusable optical laryngoscope

Abstract

The invention provides a reusable optical laryngoscope. The beneficial effects of the invention are as below: a detachable laryngoscope core body curved section sheath is clamped with a laryngoscope core body curved section; the sheath is used for replacing conventional disposable consumables; after different patients use the laryngoscope, another sheath is placed; the laryngoscope core body can be disinfected for use, thereby avoiding resource waste; meanwhile, in the sheath replacement process, the sheath is fixed through mutual clamping of fins, a caulking groove and a lower key of a key buckle; and when separation is needed, the fins are stressed to move inwards by pressing an upper key of the key buckle, the fins and the caulking groove are separated from each other by separating a convex piece of the lower key of the key buckle, and then the sheath is pulled out. The installation and disassembly process is very convenient, and the replacement process is simple; in addition, the image transmission of the laryngoscope is realized through the mutual combination of a plurality of lenses and prisms, so that an operator can intuitively and clearly see the image presented at the bottom end of the laryngoscope.

Description

【Technical field】 [0001] The invention relates to a laryngoscope, in particular to a reusable optical laryngoscope. 【Background technique】 [0002] Laryngoscope is a necessary instrument for tracheal intubation; tracheal intubation is performed under general anesthesia, muscle relaxation, hyperventilation and apnea of ​​the patient: first expose the glottis with a laryngoscope, and then place a certain curvature (20 The endotracheal tube is inserted into the trachea through the glottis to ensure the patient's oxygen supply. At present, there are two types of disposable laryngoscopes and reusable laryngoscopes. It is large, wastes resources, and cannot be reused; while the laryngoscope core of the reusable laryngoscope is inserted into the laryngoscope core sheath as a whole, and the front end of the laryngoscope core is curved. In the core sheath, the front end of the laryngoscope core is curved and divided into multiple sections that are hinged to each other. The hinged se...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that disposable laryngoscope consumables are too large, waste resources, and cannot be reused; while reusable laryngoscopes are hinged to each other, the service life is short, the number of times of use is limited, and the imaging is not ideal; the laryngoscope needs the help of electronic instruments To observe, there are many steps, and the process is cumbersome to provide an optical reusable laryngoscope
