Background Art In general an otoscope is a medical instrument simply used for a medical examination not only in an otorhinolaryngology but also in a hospital for internal diseases and a children's hospital. An otoscope used in an otorhinolaryngology is mainly composed of a main body 10 for housing battery, a lamp 12 lightened by a switch 14, and an otoscope installation unit 16 of a funnel shape for irradiating light of the lamp 12. In using the otoscope in the otorhinolaryngology, a funnel shaped pipe is insertionally combined with a front side of the otoscope installation unit 16, and then the lamp 12 is switched on, to thus, medically examine an ear through lens equipped with a back side of the otoscope installation unit 16. In a generally used otoscope, light irradiated from the lamp 12 is passed through the otoscope installation unit 16 equipped with the otoscope, to lighten the interior of the ear.

An external auditory meatus of a human being overall curves as an S shape, and is partially blocked by tragus, and furthermore, hairs or earwax in the external auditory meatus interrupts an inspection using the otoscope.

Therefore a user checks the interior of ear, pushing out the tragus or fine hairs out through a general use of a leading end of the otoscope. In the meantime, in case there is much earwax in the external auditory meatus, the user has to remove the earwax by using the ear-pick through one hand of the user, under such a state that another hand supports the otoscope. This causes an inconvenience and a medical examination time to be prolonged and a feeling of uneasiness for a patient.

Disclosure of Invention Accordingly, features of the present invention is to provide an ear-pick for an otoscope, which is capable of rapidly and conveniently removing a foreign substance of an ear interior such as earwax in a medical treatment of an otorhinolaryngology, thereby increasing a safety and a pleasantness of a patient.

That is, the user can easily medically examine or treat the interior of an ear.

An otoscope generally used in an otorhinolaryngology is provided with the otoscope installation unit 16 through which light irradiated from the otoscope lamp 12 is passed to lighten the interior of an ear. In the present invention, the lower body 20 of the ear-pick has the stopping jaw 20a that is attachable to or detachable from the concave flute 16a of the otoscope installation unit. Further, in the ear-pick for an otoscope of the present invention, the upper body 30 of the ear-pick can have a body end 30c that a leading end of the upper body becomes narrow. According as the leading end of the upper body 30 in the ear-pick for the otoscope becomes narrow, light irradiated from the otoscope lamp can be concentratively passed through, to lighten the interior of an ear. The ear-pick for the otoscope also has a protrusion

30a, 44 formed in a leading end thereof. The upper body 30 and the lower body 20 are combined with each other, interposing each of circular type beads 20b, 30b therebetween, to be then rotated relatively to each other.

In the ear-pick for the otoscope, the protrusions 30a, 44 of the upper body 30 are formed in a spherically arch shape with a determined curvature Rl, R2, R3 so as to easily capture foreign substances within an ear. Such an ear-pick for an otoscope can be easily used not only in an otorhinolaryngology but also in a hospital for internal diseases and a children's hospital.

Further, the concave flute 16a is formed in the otoscope installation unit 16 so that the ear-pick is attachable thereto and detachable therefrom. In the otoscope, a battery is accepted in the main body 10, and a switch 14 is equipped in an outer face of the main body 10.

In the ear-pick of the invention, the lower body 20 and the upper body 30 are provided as a piped member of a funnel shape like the otoscope installation unit 16, and the external faces thereof have a similar curvature and have a shape that the curved face is extended. The lower body 20 internally has the stopping jaw 20a that is matched to and combined with the concave flute 16a of the otoscope installation unit 16. The concave flute 16a of the otoscope installation unit 16 is formed through a given section in a spirally slanted direction, and its depth is not regular and has a slope to pierce through a determined section. The stopping jaw 20a of the lower body 20 is formed with determined width and height to be combined with the concave flute 16a of the otoscope installation unit 16.

In the inventive ear-pick, a rod formed extendedly from a portion of the upper body 30 of a piped shape and formed in a gradually narrowed shape is

provided as a portion inserted into an external auditory meatus of a patient.

The protrusion 30a is provided as a portion for capturing a foreign substance such as earwax in the external auditory meatus and is formed upward and downward with a given interval of, e. g. , 1. 5-2. 5mm.

The lower body 20 and the upper body 30 can be made of metal, plastic or tree material. In using plastic material, an injection molding can be used desirably. From a viewpoint of a formality, an endurance and an elasticity, polycarbonate can be used desirably.

In the inventive ear-pick for an otoscope, the upper body 30 and the lower body 20 are combined with each other, interposing each of circular type beads 20b, 30b so as to be rotated relatively to each other. In an outer circumferential face of the lower body 20, the circular type bead 20b projected with a curvature of about R0. 5 is formed, and in an inner circumferential face of the upper body 30, the circular type bead 30b recessed by the same curvature is formed. The lower body 20 and the upper body 30 are combined with each other through the circular type beads 20b, 30b to be attachable to and detachable therefrom. Also, a direction of the protrusion 30a can be easily converted by turning the upper body 30. Since the foreign substance of the earwax is generally spread on an overall face of the external auditory meatus, a distribution state of the earwax can be checked and removed, turning the upper body 30, under such a state that the lower body 20 and the upper body 30 are combined with the otoscope installation unit 16 and the otoscope lamp 12 is turned on.

The aperture 30c of the upper body 30 as a final outlet of light irradiated from the otoscope lamp 12 can have a diameter of about 5-9mm

which is maintained desirably. To prevent a visual field of a user from being narrowed, the aperture 30c of the upper body 30 is cut on the slant, desirably.

An external face curvature of the funnel shape is formed, being gradually lessened toward an end part of the upper body 30 and being gradually thinned, thus such an ear-pick can be used simply and easily for children whose external auditory meatus is small. While, an internal face of the lower body 20 and the upper body 30 is formed by a surface illumination for maintaining an appropriate irregular reflection, so as not to interfere a use of the otoscope due to a reflection phenomenon of light from the scope lamp 12.

The protrusions 30a, 44 of the upper body 30 are formed in a spherically arc shape with a determined curvature (R1) (R2) (R3) to easily capture a foreign substance. A rod portion of the upper body 30 is formed as a curved face having a first curvature Rl, and a leading end provided as the protrusion 30a has a concave sphere face with the first curvature Rl and a second curvature R2. The protrusion 30a positioned in such a sphere face is formed in an arc shape through a third rate R3 of other direction. Accordingly, the foreign substance of the earwax is captured between doubled protrusion 30a and is stably gathered in the portion concaved in the sphere face and the arc structure in the midst of taking out the earwax to the outside. Therefore, a medical examination and treat time can be reduced because there is no need to repeat such operation several times.

Industrial Applicability As described above, an ear-pick is equipped with an otoscope as a medical instrument used not only in an otorhinolaryngology but also in a

hospital for internal diseases and a children's hospital, therefore a foreign substance such as earwax can be removed rapidly and conveniently in a medical treatment of the otorhinolaryngology, to increase a safety and a pleasantness of the medical treatment. In addition, the ear-pick for an otoscope, which is inserted into the interior of a fixed pipe and fixed thereto, can be used for easily medically checking and treating the interior of an ear by holding a handle of the ear-pick and moving an ear-pick body forward and backward repeatedly or rotating it. Accordingly, the ear-pick for an otoscope is considerably useful for an industry of medical instruments.
