Abstract
The present invention relates to a kind of medical nasopharynx and check mirror, be applicable to that medical ENT doctor carries out the inspection of nasopharynx part to the patient.It connects post (5), bulb (6), handle (7), power supply wiring (8) and lead (9) by reflecting mirror (1), light-collecting lens (3), optical fibre tube (4), reflecting mirror and is formed; It utilizes optical fiber technology that light source is introduced into the pharyngeal of patient; directly to nose, the pharyngeal inspection; luminosity is strong; illumination is even; the soft shadow-free of light; the inspection eyeglass can be protected no mist for a long time, and having cancelled in the past, the doctor checks auxiliary equipment such as the outer light source of patient's nasopharynx part utilization, frontal mirror and heating eyeglass.
Description
The present invention relates to a kind of medical nasopharynx and check mirror, be applicable to that the ENT doctor of hospital carries out the inspection of nasopharynx part to the patient.
Usually the ENT doctor is when checking patient's nasopharynx part clinically, and light source is by being worn over the reflectoscope of doctor's neck, checks that mirror then will bake hotly on alcohol burner, just puts the pharyngeal of patient into, utilizes outer source reflection on the inspection minute surface, and nasopharynx part is observed.If observing time is of a specified duration slightly, pharyngeal dampness makes checks the minute surface atomizing, can not observe, and brings inconvenience to the ENT doctor.
The object of the present invention is to provide a kind of optical fiber technology that utilizes that light source is introduced into the pharyngeal of patient, utilize semistor, make reflecting mirror constant temperature heating mist elimination, directly the optical fibre fogless nasopharyngoscope that nasopharynx part is checked.
Below in conjunction with drawings and Examples the present invention is described in detail.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the profile of reflecting mirror of the present invention.
1-reflecting mirror 2-semistor 3-light-collecting lens
4-optical fibre tube 5-reflecting mirror connects post 6-bulb
7-handle 8-power supply wiring 9-lead
10-thin conductive metal sheet 11-conductive metal sheet 12-felt pad
The present invention connects post (5), bulb (6), handle (7), power supply wiring (8) and lead (9) by reflecting mirror (1), light-collecting lens (3), optical fibre tube (4), reflecting mirror and is formed; Be provided with bulb (6) in the handle (7), bulb (6) is connected with power supply wiring (8), and optical fibre tube (4) is socketed in the front end of handle (7), and its front is provided with light-collecting lens (3), and top is provided with reflecting mirror and connects post (5); Reflecting mirror (1) faces light-collecting lens (3), being socketed in reflecting mirror connects on the post (5), be provided with thin conductive metal sheet (10) in it, thin conductive metal sheet (10) is connected with semistor (2), the other end of semistor (2) is connected with conductive metal sheet (11), conductive metal sheet (11) links to each other with lead (9), and its rear end is provided with felt pad (12); Lead (9) passes reflecting mirror and connects in the post (5) and be connected with bulb (6).After the energized, semistor (2) heating makes the temperature of the glass-mirror of reflecting mirror (1) reach 60 ℃.
After the energized, bulb (6) is shinny, light source is by optical fibre tube (4), be radiated on the reflecting mirror (1) by light-collecting lens (3) again, when this product is put into patient's nasopharynx part, then whole nasopharynx part is illuminated in reflection, and doctor's direct observation minute surface just can be recognized the pathological changes situation of patient's nasopharynx part.Simultaneously, the semistor (2) in the reflecting mirror (1) after energized 20 seconds promptly generates heat to 60 ℃, makes the mirror surface heating rapidly, eliminates the atomizing of pharyngeal dampness to minute surface, makes minute surface keep clear.
Advantage of the present invention: (one) utilizes optical fiber technology that light source is introduced into the pharyngeal of patient, directly pharynx nasalis is checked that luminosity is strong, and illumination is even, and the soft shadow-free of light has been cancelled the auxiliary equipment such as outer light source and frontal mirror; (2) check that eyeglass keeps not having mist for a long time, make things convenient for the doctor to check, cancelled the past with the roasting minute surface of alcolhol burner with in the hot work of doctor's the back of the hand examination.
Claims (2)
