Disposable tube core for laryngoscope

Abstract

The invention discloses a disposable tube core for a laryngoscope. The disposable tube core comprises a connecting terminal, a tube body, a positioner and a probe. The connecting terminal and the probe are fixedly connected at two ends of the tube body respectively, and the positioner slidably connected with the tube body is located between the connecting terminal and the probe; the connecting terminal comprises an audio connector; the probe electrically connected with the audio connector is used for acquiring image information; the frictional resistance between the positioner and the tube body prevents the positioner from sliding relative to the tube body to realize positioning; the tube body is flexible; the audio connector is connected with a connector of an external display device, andis used for transmitting the image information acquired by the probe to the display device for observation by medical staff. In the working process, the outer wall of the tube body is bent after being squeezed by the inner wall of the throat, the tube body is inserted along the throat to reduce the squeezing force on the inner wall of the throat, and operations such as shaping and epiglottis bypassing are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable tube core for laryngoscopes. Background technique [0002] Due to the deep position of the larynx and the complex physiological structure, it cannot be directly observed. A laryngoscope is used as an auxiliary for airway intubation during anesthesia surgery. In the traditional laryngoscopy method under anesthesia, the surgeon holds the laryngoscope with the left hand, and sends the laryngoscope into the oral cavity along the back of the tongue, transfers it to the midline and reaches the base of the tongue. The distal end points to the posterior pharyngeal wall without touching it. After seeing the epiglottis tubercle clearly, lift the laryngoscope with a parallel upward force with the left hand, press on the epiglottis, and lift it completely to expose the laryngeal cavity. [0003] However, the existing laryngoscope external structural parts are made of h...
