Electronic visual laryngoscope

Abstract

The invention discloses an electronic visual laryngoscope which solves the problem that in the current electronic visual laryngoscope, observation of the image in the display is affected because a display and a handle can not be relatively moved, thus the technical measure that the electronic visual laryngoscope is adopted. The electronic visual laryngoscope comprises a display, a handle and a lens, wherein the lens is connected with one end part of the handle; the display is movably connected with the other end part of the handle through a coupling head; the visual laryngoscope is characterized in that the coupling head comprises a coupling body A and a coupling body B which can be connected in a relative rotation manner; the coupling body A and the coupling body B are fixed relative to the axial direction; the coupling body A is connected with the display; a connecting piece is arranged on the coupling body B; the connecting piece can be rotatably connected with the other end part of the handle; a friction damping structure C is arranged between the coupling body A and the coupling body B; and a friction damping structure D is arranged between the connecting piece and the other end part of the handle.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a visualization tool used for pressing the epiglottis to display the internal situation of the larynx during human tracheal intubation or diagnosis and treatment of laryngeal diseases. technical background [0002] The laryngoscope can be used as a tool for exposing the glottis during tracheal intubation during induction of general anesthesia and on-site cardiopulmonary resuscitation. A laryngoscope is required. The function of the laryngoscope requires that the laryngoscope needs to be equipped with a display device, so that the condition of the patient's larynx can be clearly understood when performing corresponding medical activities. [0003] A Chinese utility model patent (patent number: 200820021599.7) discloses a laryngoscope, which includes a handle and a lens. The lens is movably connected to the handle. The inner cavity of the handle is provided wit...

Problems solved by technology

[0004] The display device in this laryngoscope is fixedly connected to the handle, that is, the display device does not move relative to the handle. In the middle, the handle can rotate relative to the lens, but limited by the chin of the human body, the range of motion of the handle cannot be too large. This motion is reflected on the display device, and the actual deflection range of the display device is quite limited. This is not very suitable for many people to watch the pictures in the display device, and it is also easy to cause damage to the inside of the patient's oral cavity, especially the larynx

Therefore, this kind of laryngoscope is inconvenient to participate in the communication between doctors during the consultation and treatment of patients, and it is also inconvenient for the communication between doctors and patients' families.
