Abstract
The utility model relates to an inspection instrument of clinical ENT departments, which is suitable for inspecting pathological changes of external auditory meatus. The utility model comprises a casing, an electrical power supply, a light source, a switch, a dark box, a mirror mouth, a magnifier, and an ear speculum. The utility model utilizes a transmission light system of optical fibers to enable inner ears to get light, and is provided with the magnifier, so doctors can examine various pathological changes of the external auditory meatus and the drum clearly. The utility model can be use for operations of external auditory meatus and air-blowing inspection. The utility model has the advantages of small size, convenient portability.
Description
This utility model belongs to a kind of clinical ear larynx section inspection apparatus, is applicable to the pathological changes of checking external auditory meatus.
Common clinical examination external ear pathological changes, as hyperemia, swelling, the muddiness of external auditory meatus hyperemia, swelling, ceruminal impaction, foreign body, abscess, fistula and inspection ear drum membrane, thicken, pathological changes such as perforation, atrophy, cicatrix, calcium speckle, muddiness, hydrotympanum, all need by the auriscope inspection.Domestic its structure of widely used auriscope comprises power supply, light source, camera bellows, magnifier at present, and light source is directly injected illumination in the camera bellows outside, and bulb influences doctor's the visual field; Simultaneously magnifier is too little, unfavorable observation, and it is open that camera bellows is, can not air-blowing, can not operate.
The purpose of this utility model is to provide a kind of optical fibers optically focused that utilizes, the multifunctional optical fiber electric auriscope of being convenient to the external auditory meatus inspection and operating.
Task of the present utility model is done in such a way that by two joint 1.5V No.5 cells make bulb shinny, light is penetrated at the fibre-optic bundle bright finish, and light reaches the optical fibers ring along fibre-optic bundle, makes light source luminous in ear; The doctor can clearly observe the pathological changes situation of in ear along camera bellows by magnifier.When operating, magnifier is pushed to a side, can stretch to the in ear operative site to operating theater instruments along camera bellows as need.
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-shell 2-power supply 3-light source 4-camera bellows
5-mirror mouth 6-magnifier 7-fibre-optic bundle bright finish
8-optical fibers ring 9-air-blowing hole 10-ear is peeped the 11-on and off switch
This utility model is peeped institute by shell, power supply, light source, switch, camera bellows, Jing Zui, magnifier, ear and is formed.Shell (1) forms with plastic injection-moulded, power supply (2) with two the joint 1.5V No.5 cell, on and off switch is (11), light source (3) is positioned at the place ahead of power supply (2), be a 0.25A, 2V, 0.5W miniature bulb, one side has an air-blowing hole (9) in camera bellows (4) center, there is a fibre-optic bundle bright finish (7) below, there is a Jing Zui (5) in the place ahead, Jing Zui (5) has an optical fibers ring (8) that is extended to form by fibre-optic bundle bright finish (7), it is one mobilizable that the rear has, amplification is 3～5 times a magnifier (6), fibre-optic bundle bright finish (7) and optical fibers ring (8) are made of the optical fiber wire of φ 0.3～0.4mm, constitute the photoconduction conducting system jointly; Jing Zui (5) can put the ear of different size and peep (10), so that insert external auditory meatus.
Using method: connect suitable ear at Jing Zui (5) and peep (10), energized switch (11) is peeped the external auditory meatus of inserting patient to ear, and the doctor promptly can be observed patient's auditory meatus and diaphragm-operated various pathological changes by magnifier (6); As need operations, magnifier can be pushed to a side, operating theater instruments can be passed ear from camera bellows (4) and be peeped and operate; During air-blowing, the rubber bulb is inserted air-blowing hole (9), get final product air-blowing.
Advantage of the present utility model is: it is shinny and with magnifying glass that (1) utilizes the optical fiber conducting system to make in the ear, can clearly observe the various pathologies of patient's external auditory meatus and eardrum; (2) push magnifying glass open, can do external auditory meatus operation, and also can do the air-blowing inspection; (3) volume is little, and is easy to carry.
Claims (3)
1, a kind of multi-functional photoconduction fiber electric auriscope, its structure comprise that shell, power supply, switch, camera bellows, Jing Zui, magnifier, ear peep, and it is characterized by:
(1) light source (3) is positioned at the place ahead of power supply (2), is the miniature bulb of 0.25A, a 2V, 0.5W;
(2) center one side of camera bellows (4) has an air-blowing hole (9), there is a fibre-optic bundle bright finish (7) below, there is a Jing Zui (5) in the place ahead, Jing Zui (5), Jing Zui (5) has an optical fibers ring (8) that is extended to form by fibre-optic bundle bright finish (7), and that the rear has is one mobilizable, amplification is 3～5 times magnifier (6).
2, multi-functional photoconduction fiber electric auriscope according to claim 1 is characterized by fibre-optic bundle bright finish (7) and optical fibers ring (8) and is made of the optical fiber wire of φ 0.3～0.4mm.
3, multi-functional photoconduction fiber electric auriscope according to claim 1 is characterized by the ear that Jing Zui (5) can put different size and peeps (10).
