Description

An easy-to-observe electronic laryngoscope

technical field

The invention relates to the technical field of medical appliances, in particular to an electronic laryngoscope for easy observation.

Background technique

The physiological structure of the human larynx is very complex, and it is impossible to directly observe the situation inside. When a disease occurs, it needs to be observed with the help of some special medical equipment to determine the disease. Laryngoscope is a kind of medical equipment specially designed for laryngeal examination according to this situation. There are many types of laryngoscope. Electronic laryngoscope has the advantages of less stimulation, no pain, high-definition examination screen, convenient and easy operation, and short operation time. It has become the most easily accepted examination method for patients. When using the traditional electronic laryngoscope to examine the patient, first use the curved laryngoscope blade to press the patient's tongue to the lower jaw to open the throat, and then use the built-in high-definition camera and LED light source for observation. For some subjects with heavy gag reflex, because the tongue is only subjected to a lateral pressure and is not fixed, it will still curl inward due to the nausea reflex, blocking the throat, thereby hindering the examination and affecting the shooting of the camera.

Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings 1-2, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so that the protection scope of the present invention can be more clearly defined .

In order to improve the stability of shooting during laryngoscope observation, this embodiment discloses an electronic laryngoscope for easy observation, including a handle 1, a display 2, laryngoscope blades 3 and a tracheal intubation 4, and the display 2 is movably connected to the handle 1. The top of the handle can be bent at multiple angles to facilitate the medical staff to adjust the viewing angle during the operation. A connecting stake 5 is arranged at the bottom of the handle 1, and one end of the tracheal intubation tube 4 is fixedly connected to the end of the connecting stake 5, and the other One end is provided with an LED light source and a camera, and the internal image of the oral cavity captured by the camera is output on the monitor 2 in real time. The laryngoscope blade 3 is arranged above the tracheal intubation tube 4, and one end of the laryngoscope blade 3 is connected with the connecting pile 5 by plugging, and is connected to the throat. A tongue fixing device 6 is provided on the side of the mirror blade 3 that is inclined to the connecting pile 5. The specific setting position is adjusted according to the average distance from the throat to the tip of the tongue for most people after sampling and investigation. (Especially between children and adults) the distance from the throat to the tip of the tongue is quite different. At the same time, different specifications of laryngoscope blades 3 are provided for people of different ages to choose and use.

The surface of the laryngoscope blade 3 is coated with a nanometer anti-fogging coating, which can avoid the influence of the fog film and respiratory secretions on the observation caused by the temperature difference during the intubation process.

The tongue fixing device 6 includes a fixed frame 61 and an air bag 62 arranged on the inner side of the top of the frame. A ventilation duct 63 is provided laterally inside the fixed frame 61. Connected to the balloon 65, a balloon switch 66 is provided on the end of the balloon hose 64 close to the balloon 65, and the ventilation pipe 63 is arranged in the lateral direction to prevent the balloon hose 64 from colliding with the tongue during use. position interference.

The connecting end of the balloon hose 64 and the ventilation pipe 63 is provided with a plastic connecting section, an external thread is provided on the outer surface of the plastic connecting section, and an internal thread is provided inside the ventilation pipe 63, and the plastic connecting section is connected with the ventilation pipe. The threaded connection 63 completes the communication between the balloon hose 64 and the ventilation pipe 63 . The balloon hose 64 and the balloon 65 can be separated from the tongue fixing device 6, so that the laryngoscope blade 3 and the tongue fixing device 6 can be sterilized separately after being disassembled from the connecting pile 5, which is more convenient for operation.

The fixed frame 61 has an elliptical arc shape as a whole to ensure the comfort of the tongue in contact with the frame, and the inner surface of the fixed frame 61 is covered with a rubber layer to further protect the tongue.

The outer surface of the airbag 62 is provided with anti-skid protrusions, and there is no restriction on whether it is a twill protrusion, a point protrusion or a diamond protrusion, as long as it can play a non-slip effect.
