Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and more specifically, to an adaptive anti-fog laryngoscope. Background Art

[0002] The pharynx is a common passage for breathing and digestion, and has important physiological functions such as swallowing, breathing, and phonation. Since the pharynx is located deep and almost at right angles to the oral cavity, it cannot be directly viewed during ordinary physical examinations, so throat examinations require the use of some special examination methods or instruments. Indirect laryngoscopy is currently the most commonly used non-invasive and non-invasive throat examination method in clinical practice. It has the advantages of being simple, easy to master, and less painful for patients.

[0003] The indirect laryngoscope is a circular plane mirror with a handle. The mirror surface intersects with the handle at 120°, and the diameter of the mirror surface varies. During the examination, an indirect laryngoscope of appropriate size is selected according to the subject's pharyngeal condition for exogenous heating and examination.

[0004] At present, the indirect laryngoscope used in clinical practice has the following problems:

[0005] 1. The angle between the mirror surface and the mirror handle of the indirect laryngoscope in the prior art is fixed at 120° (the mirror surface and the mirror handle intersect), and the angle between the mirror surface and the mirror handle cannot be adjusted according to the conditions of the examinee. For some examinees with high tongue position, large tongue, narrow pharyngeal cavity, abnormal epiglottis morphology, etc., the ordinary indirect laryngoscope angle cannot complete the examination;

[0006] 2. The indirect laryngoscope in the prior art has a poor anti-fogging effect. Some technologies use some electric heating defogger elements involving circuits to achieve anti-fogging, which is inconvenient for the disinfection operation of the laryngoscope; some technologies use exogenous heating, and the heating time, temperature and heating effect are difficult to control. If the heating time is too short, the defogger effect is poor; if the heating time is too long, it is easy to burn the throat mucosa of the examinee; some technologies use chemical spray anti-fogging agents, which may have adverse effects on the human body. Utility Model Content

[0007] The purpose of the utility model is to solve the above problems and provide an adaptive anti-fog laryngoscope so as to provide more inspection angle options and a safer and more reliable mirror anti-fog solution.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] An adaptive anti-fog laryngoscope comprises a mirror surface, a handle and an adaptive angle adjustment joint, wherein one end of the adaptive joint is connected to the mirror surface, and the other end of the adaptive joint is connected to the handle; a detachable disposable mirror sterile anti-fog patch is provided on the back of the mirror surface.

[0010] By adopting the above technical solution, the mirror and the handle are designed to be connected by an adaptive joint, which makes it convenient to adjust the angle between the mirror and the handle according to the condition of the examinee or the operation during use, thereby avoiding the limitations of the indirect laryngoscope in the prior art that the angle between the mirror and the handle is fixed and difficult to adjust, the throat cannot be fully exposed, and it is difficult to complete the examination.

[0011] Furthermore, the angle between the mirror and the handle is adjusted through an adaptive joint, and the adjustment range of the angle between the mirror and the handle is: 90-150°.

[0012] By adopting the above technical solution, the angle adjustment range between the mirror and the handle is: 90-150°, which is convenient for adjusting the angle range between the mirror and the handle according to needs during use, thereby achieving better exposure of the throat and improving the efficiency and effect of throat inspection.

[0013] Furthermore, the adaptive joint adopts a spherical joint or a universal joint.

[0014] By adopting the above technical solution, the angle adjustment operation between the mirror surface and the handle can be easily realized.

[0015] Furthermore, the disposable mirror-surface sterile anti-fog patch is a disposable sterile heating patch, the heating temperature of the anti-fog patch does not exceed 55° C., and the heating duration is 5 minutes.

[0016] By adopting the above technical solution, it is easy to realize the function of heating the mirror surface after sticking it to the back of the mirror surface to defog the mirror surface. It also ensures the sterility of the instrument and avoids cross infection. At the same time, it avoids the situation that conventional electric heating defogger is inconvenient to perform disinfection operations. It also avoids the situation that the heating time, temperature and defogger effect cannot be controlled during the exogenous heating process, and avoids scalding the throat mucosa of the examinee.

[0017] Furthermore, a patch area for sticking a disposable mirror sterile anti-fog patch is provided on the back of the mirror.

[0018] By adopting the above technical solution, a patch area is set to facilitate the sticking operation of the disposable mirror-surface sterile anti-fog patch and ensure the heat conduction effect.

[0019] In summary, the utility model has the following beneficial effects:

[0020] Through the adaptive anti-fog laryngoscope of the utility model, on the one hand, the angle between the mirror and the handle can be flexibly adjusted, and the adjusted angle can be stabilized after adjustment, which facilitates the inspection operation according to the actual situation of the subject's pharyngeal cavity and improves the inspection efficiency and accuracy. In addition, the defog method of the adaptive anti-fog laryngoscope adopts a disposable sterile anti-fog patch, which has reliable heating efficiency and better anti-fog effect. The heating temperature is fixed to avoid scalding the pharyngeal mucosa of the subject; and the defog operation is convenient, avoiding the limitations and inconveniences caused by the use of electric heating defog elements in some existing technologies for cleaning and disinfecting laryngoscopes, and also avoiding the adverse effects of chemical spray anti-fog agents used in some existing technologies on the human body.
