Abstract
The utility model relates to a nasopharynx inspectoscope for medical application and is suitable for a doctor in an otolaryngology department to inspect patients' nasopharyngeal parts. The utility model is composed of a reflection mirror (1), a positive temperature coefficient thermistor (2), a spotlight ophthalmic lens (3), an optical fiber tube (4), a joint pin of the reflection mirror (5), a light bulb (6), a handle (7) and a power supply wiring (8). The utility model uses the technique of light conducting fiber to bring light sources into patients' pharyngeal parts and inspect the nasopharyngeal parts directly, the luminosity is strong, the light irradiates evenly, the light ray is soft and has no shadows, the ophthalmic lens for inspection can keep a state without mist for a long time, and the utility model avoids the use of auxiliary facilities such as external light sources, head mirrors, etc., which are used by doctors to inspect patients' nasopharyngeal parts in the past.
Description
This utility model relates to a kind of medical nasopharynx and checks mirror, is 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 purpose of this utility model is to provide a kind of optical fiber technology that utilizes that light source is introduced into the pharyngeal of patient, utilizes semistor, makes 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 this utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
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
This utility model connects post (5), bulb (6), handle (7) and power supply wiring (8) by reflecting mirror (1), semistor (2), 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), buried a semistor (2) below its glass lens, the speculum shell of the one side contact reflex mirror (1) of semistor (2) (the speculum shell is as a utmost point of power supply), the another side contact is passed reflecting mirror and is connect in the post (5) and the lead (9) (another utmost point of power supply) that is 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, be imbedded in semistor (2) in the reflecting mirror (1) after energized 20 seconds, promptly generate heat, make the mirror surface heating rapidly, eliminate of the atomizing of pharyngeal dampness, make minute surface keep clear minute surface to 60 ℃.
Advantage of the present utility model: (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, the cancellation past is with the roasting minute surface of alcolhol burner with in the hot work of doctor's the back of the hand examination.
Claims (2)
1, a kind of optical fibre fogless nasopharyngoscope is characterized in that:
A. connecing post (5), bulb (6), handle (7) and power supply wiring (8) by reflecting mirror (1), semistor (2), light-collecting lens (3), optical fibre tube (4), reflecting mirror is formed;
B. 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);
C. reflecting mirror (1) faces light-collecting lens (3), is socketed in reflecting mirror and connects on the post (5), has buried a semistor (2) below its glass lens.
2, optical fibre fogless nasopharyngoscope according to claim 1, the speculum shell that it is characterized in that the one side contact reflex mirror (1) of semistor (2), another side contact pass reflecting mirror and connect in the post (5) and the lead (9) that is connected with bulb (6).
