Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to antifog indirect laryngoscope with adjustable angle.
Background
The indirect laryngoscope is a tool used by doctors in otolaryngological department for routine examination of throat, and is composed of a lens, a lens fixing shell and a handle, wherein the handle is a steel wire with the diameter of 3-5 mm and the length of 20mm, and the steel wire and the lens are fixed and can be fixed into a whole and form a certain angle, and the examination can be performed only by means of the indirect laryngoscope on the pathological changes of the throat and the hypopharynx. When in examination, the patient sits up, opens the mouth and stretches the tongue, the examiner sits on the opposite side of the patient, the focus of the reflected light of the frontal mirror is adjusted to the oropharynx of the patient, the indirect laryngoscope is held by the right hand, and the mirror surface is slightly heated on the alcohol lamp, so that the fogging during examination is prevented. After heating, firstly testing the temperature on the back of the hand of the examiner, and when confirming that the patient is not scalded, placing the indirect laryngoscope into the oropharynx of the patient. During examination, the mirror surface forms an angle of 45 degrees with the ground, the back of the mirror pushes the uvula and the soft palate to the back and the upper part, and the tongue root, the epiglottis valley, the pyriform fossa and the like can be seen. Therefore, the indirect laryngoscope used clinically has the following disadvantages: (1) the indirect laryngoscope does not need a light source, the light source is provided by wearing a frontal mirror by means of an ear-nose-throat workbench and a doctor, the distance of light irradiated by the light source of the ear-nose-throat workbench is relatively far, the light source needs to be adjusted repeatedly by the doctor, the light passes through the oral cavity to reach the mirror surface and see the tissue structure reflected by the mirror surface, the finger holding the indirect laryngoscope can continuously adjust the angle of the mirror surface to adapt to the requirement of examination, and the doctor in the ear-nose-throat department can achieve the mutual matching of the light source of the ear-nose-throat workbench, the eye, the frontal mirror and the ear-nose-throat workbench through professional training to perform the examination. When the throat emergency of the patient is faced, or under special conditions without a workbench, such as bedside and emergency treatment, doctors cannot timely examine the patient. (2) The purpose of alcohol burner heating mirror surface is to prevent that the mirror surface from fogging, and the temperature of heating is uncontrollable, and the water smoke still can appear in the low temperature, and the patient can be scalded to the high temperature. (3) The mirror surface is a common mirror surface, and can not be clearly displayed for tiny pathological changes, thereby delaying the treatment of patients. (4) The mirror surface and the handle are fixed in angle, so that the observation angle is limited.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an angle-adjustable anti-fogging indirect laryngoscope with simple structure and convenient operation for solving the problems of no light source, incapability of randomly adjusting the angle of a handle and easy fogging of a mirror surface existing in the prior indirect laryngoscope.
In order to achieve the above object, the utility model adopts the following technical scheme: an angle-adjustable anti-fog indirect laryngoscope comprising a laryngoscope consisting of a lens and a fixed shell and a handle, wherein: the laryngoscope is movably connected with the handle through a rotating shaft; the periphery of the lens is uniformly distributed with a plurality of embedded light sources, one end of the handle close to the laryngoscope is also provided with one embedded light source, and the other end of the handle is provided with a switch above, and the switch is connected with the light sources through wires arranged in the handle.
Preferably, the lens is a magnifying lens.
Preferably, the distance between the light source on the handle and the lower end of the handle is 1-2 cm.
Preferably, a layer of benzalkonium chloride wipe is applied to the lens.
Compared with the prior art, the utility model has the advantages of it is following:
(1) Because the utility model discloses be provided with the light source in the periphery of lens, saved the doctor and had to provide the trouble of light source with the help of otolaryngology workstation and the frontal mirror of wearing for the inspection is convenient and fast more, thereby has improved the effect of inspection greatly.
(2) Because the laryngoscope and the handle of the utility model are movably connected, the laryngoscope makes more convenient for the random adjustment of the angle of the handle and greatly makes more convenient for the observation angle.
(3) Because the lens of the utility model uses the magnifying glass, the lens can be clearly seen from small pathological changes, thereby avoiding missed diagnosis and delaying the treatment of patients.
(4) Because the lens of the utility model is coated with a layer of benzalkonium bromide for wiping, the atomization of the lens surface in the inspection is effectively prevented.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the angle-adjustable anti-fog indirect laryngoscope comprises a laryngoscope 1 composed of a lens 3 and a fixed shell 7, and a handle 2, wherein: the laryngoscope 1 is movably connected with the handle 2 through a rotating shaft 5; a plurality of embedded light sources 4 are uniformly distributed on the periphery of the lens 3, one end of the handle 2 close to the laryngoscope is also provided with one embedded light source 4, the other end of the handle 2 is provided with a switch 6 above, and the switch 6 is connected with the light source 4 through a wire arranged in the handle. The distance between the light source 4 on the handle 2 and the lower end of the handle is 1-2 cm. Before use, the lens 3 is coated with a benzalkonium chloride wipe to prevent fogging. For better clarity, the lens 3 is a magnifying glass.
