Abstract
An optoelectronic imaging laryngoscope comprises a laryngoscope (1), a camera (2), a display (3), a cold light source (4), and an AC electrical source (5). The utility model is characterized in that the camera (2) is directly connected with the ocular (7) of the laryngoscope (1), wherein the camera (2) is connected with input interface of video frequency of the display (3), the AC electrical source (5) is connected with the cold light source (4) and the display (3), and the ocular (7) of the laryngoscope (1) is connected with the cold light source (4) though fiber optic cables, wherein the radian (10) of the lens of the laryngoscope (1) is between 120 and 130 degrees. The device provided by the utility model utilizes the optoelectronic imaging technology to magnify the vision of the exposed laryngeal-glottic region, display and record the images throughout the process of tracheal intubation. The utility model has easy connection, simple operation, clear images, capability of memorization of digital images, and long life span.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, and more particularly it is a kind of optical electron imaging laryngoscope.
Background technology
Laryngoscope is clinical anesthesia and emergency medicine indispensable a kind of medical apparatus and instruments when carrying out tracheal intubation, laryngoscope is existing century-old history since coming out, curvatures from the light source to the eyeglass etc. several times improve just becomes the medical apparatus and instruments that today, we comparatively were suitable for, but present employed laryngoscope only exists and can the tracheal intubation operation is provided and expose the less deficiency of glottis regional vision to a doctor.When meeting difficulty tracheal intubation, traditional laryngoscope expose the glottis regional vision and image less, to the operator the correct judgement of the larynx glottis region of anatomy is brought difficulty; Traditional laryngoscope can't make higher level doctor or assistant instruct and participate in correct operating process simultaneously, thereby influences the success rate of difficult tracheal intubation.The normal person from the oral cavity to existing three to dissect axis between glottis, i.e. mouthful axis, pharynx axis and larynx axis.The oropharynx axis is mutually the right angle, the throat axis then acutangulates, in order to reach the purpose that appears glottis, use the straight laryngoscope of tradition that these three axis are hung down and build up 180 ° on a line, also must make patient head be in the posture of excessive layback, and when using traditional curved laryngoscope, the amplitude of patient's head layback reduces, be 150 °-140 ° each other in oropharynx axis, make full use of the vertical space in oral cavity, reach and expose the intubate that glottis is finished trachea.It all is to operate down the direct visual of doctor that traditional curved straight laryngoscope is finished the tracheal intubation overall process.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned background technology and a kind of optical electron imaging laryngoscope is provided, this device utilization optics and electronic imaging technology have been amplified institute and have been exposed larynx glottis regional vision, and show and write down the image that tracheal intubation is operated overall process.
The purpose of this utility model reaches by following measure, optical electron imaging laryngoscope, and it comprises laryngoscope 1, photographic head 2, display device 3, cold light source 4, alternating current power supply 5; Its special feature is that photographic head 2 directly is connected on the eyepiece of laryngoscope 1, photographic head 2 is connected with the video input interface of display device 3, alternating current power supply 5 connects cold light source 4, and the eyepiece 7 of laryngoscope 1 is connected with cold light source 4 through the fiber optic conduction line, and the radian 10 of described laryngoscope 1 eyeglass is 120 °-130 °.
In technique scheme, also comprise CD writer 7; Described CD writer 6 is connected with alternating current power supply 5, photographic head 2 and display device 3 video input interfaces respectively.
In technique scheme, the height of described laryngoscope 1 eyeglass side wall and pressure hyoplastron 9 is 15mm.
In technique scheme, the eyepiece 7 and the object lens 8 of described laryngoscope 1 eyeglass are optical frames.
In technique scheme, the Liar 8 of described laryngoscope 1 eyeglass, front end is 30 ° inclined-plane.
The utlity model has following advantage: 1. connect simple, processing ease, clear picture, digital image storage, long service life.2. become multistage doctor study by one man operation, the directiveness operation, not only the standardized operation to endotracheal intubation provides very big help, and endotracheal tube is inserted more like clockwork reliable assurance is provided in the trachea.3. because the light source weighing apparatus is fixed, eyepiece is spied on area in closely bigger, the improved radian of eyeglass is more near the physiology curvature of people's oropharynx, therefore, be not less than the patient of 1.5cm or the patient of high larynx to opening one's mouth, when implementing endotracheal intubation, larynx glottis zone can both be amplified and expose the clear ComarI of being shown as level and finish endotracheal intubation smoothly, improved the success rate of difficult tracheal intubation greatly.4. owing to be furnished with CD writer, can realize the record of endotracheal intubation overall process, and can record difficulty, pathology and the special case image variation of larynx glottis, for scientific research provides real foundation.
Description of drawings
Fig. 1 looks intention for this utility model structure,
Fig. 2 looks intention for the structure of this utility model laryngoscope.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing:
1 is that laryngoscope, 2 is that photographic head, 3 is that display device, 4 is that cold light source, 5 is that alternating current power supply, 6 is that CD writer, 7 is that eyepiece, 8 is that object lens, 9 spatulas, 10 are the radian of eyeglass among the figure.
From accompanying drawing as can be known: this utility model is made up of laryngoscope 1, opticator and three ones of electronic imagings.The curvature of preceding 1/3 part of optical electron imaging laryngoscope eyeglass is 120 °-130 °, more near the Human Physiology curvature.This laryngoscope is during as tracheal intubation, after eyeglass enters the oral cavity, is that this camera lens is on the pharynx axis substantially, reaches the purpose of spying on larynx glottis structure by 1/3 optical lens before the mirror; The height of laryngoscope 1 eyeglass side wall and pressure hyoplastron is 15mm, so that difficulty in opening mouth person's tracheal intubation is used, Liar 8 front ends of laryngoscope 1 eyeglass are 30 ° inclined-plane, can reach 16cm at the area that closely can spy on picture of 5cm
