Figure 4 is a detailed view of the image transmission unit of the portable otoscope of the present invention.

Hereinafter, a portable otoscope according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

2 and 3 show a portable otoscope of the present invention. In the portable otoscope 100 of the present invention, an image output unit 120 for outputting an image of the inside of the body is basically formed on the body 110 and a grip unit 130 formed to be easily grasped by the hand. On the opposite side of the output unit 120 is configured to have an image transmission unit 140 for taking an image of the inside of the body to transmit to the image output unit 120. At this time, the portable otoscope 100 of the present invention has a feature in the detailed configuration of the image transmission unit 140.

Features of the image transmitter 140 will be described in more detail later. First, the basic configuration of the portable otoscope 100 will be briefly described with reference to FIGS. 2 and 3.

As described above, the body 110 includes an image output unit 120 at an upper side, and a grip unit 130 formed at a lower side thereof, so that a user grasps the grip unit 130 and the image output unit 120. You can see the video output. The image output unit 120 includes an image output screen 121 and an image output screen control panel 121a, which are basic components for outputting an image. In general, the image output screen 121 may employ an LCD or the like widely used for image output of a small electronic device. The image output screen control panel 121a is an electronic circuit provided for general image output control, and may be a well-known and widely used structure. Therefore, the detailed description of the image output screen control panel 121a will be omitted. In addition, the image output unit 120 includes a CMOS sensor 122 and a CMOS sensor control panel 122a for receiving an image transmitted from the image transmission unit 140. The CMOS sensor 122 receives and senses an image transmitted through the image transmitter 140, and the CMOS sensor control panel 122a is connected to the CMOS sensor 122 to output a sensed image. It processes and converts the data into possible data and transmits the data to the image output screen control panel 121a and the image output screen 121. A CMOS sensor and a device for controlling the same may also be known and widely used, and thus the detailed description of the configuration will be omitted.

The image transmission unit 140 is basically formed to protrude on the opposite side of the image output unit 120, is inserted into the body to obtain an image inside the body to transmit the image obtained to the image output unit 120 To serve as the output.

In the related art, the image transmitter 140 is generally provided with direct illumination, or the illumination is provided at a position where the illumination can be directly reflected on the portion photographed by the image transmitter 140. Therefore, conventionally, when the image is taken, the light is directly reflected on the affected part (that is, the portion to be photographed). In spite of the fact that it is natural to use bright lights to secure the field of view, there are limitations in raising the brightness of the lights due to problems such as circuit breakage and patient inconvenience due to heat generated from the lights.

* * *

First of all, in order to eliminate the problem of the deterioration of the image quality due to the direct irradiation of the illumination, in the present invention, the structure of the image transmission unit 140 is improved as follows.

In the present invention, the image transmission unit 140 is provided in the image transmission unit body 141 formed of a double tube structure consisting of an outer tube and an inner tube, the outer tube of the image transmission unit body 141, one side of the body It is connected to the light 111 provided in the 110 and the optical fiber (112) for connection to receive the light emitted from the light 111, the other end of the image transmission unit 140 An optical fiber 142 for illumination that transmits the light received through the connection optical fiber 112 to the end side of the image transmission unit 140 to illuminate the light, and an inner tube of the image transmission unit body 141. And a phase transfer system 143 provided within the image transmission unit 140 to transfer an image obtained at an end of the image transmission unit 140.

Here, the core, the image transmission unit body 141 is made of a double tube form, the light is transmitted through the illumination optical fiber 142 disposed in the outer tube of the image transmission unit body 141 is irradiated to the affected area It is to be possible. That is, in the present invention, unlike the conventional otoscope structure in which the illumination 111 irradiates light directly on the affected part, the illumination 111 is provided inside the body 110 and the illumination 111 The light emitted from) is sequentially transmitted through the connection optical fiber 112 and the illumination optical fiber 142 (connected thereto and disposed in an outer tube of the image transmission unit body 141). It is delivered to the end of 140 to illuminate the affected part. At the end of the image transmission unit body 141 is focused of the captured image. At this time, the illumination optical fiber 142 is disposed in the outer tube of the image transmission unit body 141, that is, the light can be irradiated very uniformly to the periphery of the part where the image is taken.

Accordingly, the problem that the image is blurred by the light or the image quality is deteriorated due to the reflection, which is generated by directly irradiating light, is greatly improved, and thus a clearer and better image can be obtained. In addition, since the illumination 111 does not need to be directly provided near the affected part, in the present invention, it is possible to realize a cold light illumination. Thus, the problem of heat dissipation caused by the illumination 111 near the affected part is eliminated to some extent. You can do it. In the drawing, the illumination 111 is shown as being provided inside the gripping portion 130, but of course, this is just one example, and the illumination 111 may be provided anywhere on the body 110.

In addition, it is preferable that the illumination 111 generally use LEDs that are widely used as illumination of such small electronic devices. Of course, it is natural that the lighting control panel 111a for controlling the lighting 111 is provided in the body 110, and in addition, the lighting control unit 111b for controlling the brightness of the lighting 111. ) May be further provided. The lighting control panel 111a will be described in more detail later.

In addition, in the present invention, to improve the configuration of the image delivery system 143 to improve the quality of the image. Figure 4 is a detailed view of the image transmission unit of the otoscope of the present invention, two embodiments of the phase delivery system 143 is shown in Figure 4 (A), (B), respectively.

In the first embodiment illustrated in FIG. 4A, the image transmission system 143 includes an objective lens 143a provided at the end side of the image transmitting unit 140 and an eyepiece lens 143b provided at the opposite end side. ), A plurality of relay lenses 143c provided between the objective lens 143a and the eyepiece 143b, and the image obtained by the objective lens 143a through the eyepiece 143b. It is adapted to transfer to the CMOS sensor 122. In this way, the objective lens 143a-the plurality of relay lenses 143c-the eyepiece 143b are collectively called a relay lens system. In the first embodiment of the image transfer system 143, the introduction of the relay lens system in this way can further increase the clarity of the image obtained.

In the actual implementation of such a relay lens system, when the outer diameter of the relay lens system is configured to about 2.7mm to 4.0mm and the length of about 90mm, (the device name of the present invention is observed as the 'opticoscope', the inside of the ear It's easy to see inside the nose as well as the ear. That is, the portable otoscope 100 of the present invention can be utilized to observe the inside of the body anywhere as well as inside the ear.

In the second embodiment shown in FIG. 4B, the image transfer system 143 is made of image fiber, and the image obtained from the end of the image transmission unit 140 is transferred through the image fiber. It is configured to transmit to the sensor 122.

An image fiber is a glass fiber for transmitting an image, in which a bundle of hundreds of thousands of glass fibers having a diameter of about several tens of micrometers is bundled to form a cable. At this time, one strand of glass fiber serves as one pixel, and the image can be transmitted regardless of the refraction of the cable through total internal reflection. Such image fibers are flexible because images can be transmitted irrespective of refraction as described above, and can be transmitted in a range of several meters, and have been applied to gastroscopes and the like. In the second embodiment, the structure for image transmission using the image fiber can adopt the structure applied to the existing apparatus as it is, and thus, detailed structures other than the image fiber will be omitted.

In addition, the image transmission unit 140, the tip 150 as shown in Figure 3 (A), (B) can be detachably connected to the end by the tip connecting means 151. The tip connecting means 151 may be made of any structure because it may be made to simply connect the end of the image transmitting unit 140 and one end of the tip 150. 3 (A) and (B), the tip connecting means 151 is connected to the end of the image transmission unit 140 by screwing, and one end of the tip 150 is inserted and coupled therein. The structure for connecting the image transmitter 140 and the tip 150 is illustrated. Of course, the present invention is not limited thereto, and the structure of the tip connection means 151 may be variously modified within a range not departing from the technical spirit of the present invention.

The tip 150 is composed of an outer tube and an inner tube and is formed in a double tube form in which an optical fiber is provided in the outer tube, and is bent in the middle so that the inside of the animal body can be observed. In the case of humans, the structure from the ear to the eardrum is a straight structure, but in the case of a dog, for example, the structure is curved about 70 ㅀ. Therefore, the otoscope having a straight structure cannot be used for observing the inside of the body of the animal, but by using the tip 150, the otoscope can be used without distinction between a human and an animal.

Similarly to the image transmission unit 140, the tip 150 is formed in a double tube form so that the optical fiber is built in the outer tube to enable cold light illumination. Similar to the image transfer system 143 of the image transmitting unit 140, the inner tube of the tip 150 may be configured to deliver an image using a lens or an image fiber. have. In the first embodiment of the tip 150 shown in Figure 3 (A), the image is transferred to a plurality of lenses (152a) provided in the inner tube of the tip 150, but in the folded portion of the image transfer path The mirror 152b is provided in the part side bent so that a direction may be changed. In addition, in the second embodiment of the tip 150 illustrated in FIG. 3B, the image is transferred to an image fiber provided in the inner tube of the tip 150.

* * *

Next, in order to eliminate the problem that there is a limit to increase the brightness of the illumination due to the heat generated in the second problem, in the present invention, the lighting 111 is controlled by the lighting control panel 111a formed in the form of an electronic substrate In this case, an overheat prevention circuit using a metal-insulation transistor (MITR) is provided in the lighting control panel 111a.

As described above, in the conventional portable otoscope, as the brightness of the light is increased, heat dissipation becomes more severe, such that there is a problem such as damage to the circuit due to overheating or discomfort of the patient. Therefore, in the case of a portable otoscope, a low power LED of 1 W or less was conventionally used as a light, and a large structure for preventing overheating was required to use a higher power LED. Therefore, it is difficult to realize miniaturization and light weight. Could not be. That is, in the past, in the case of a portable otoscope, only a low power LED of 1 W or less is used, or a high power LED provided with a structure for preventing overheat is limitedly used in a professional device for a medical institution that does not need to consider purchase cost or portability. .

However, in the present invention, by controlling the temperature not to rise above a predetermined temperature (for example, 72 ℃) by using the MITR element, it is possible to achieve miniaturization and light weight in the implementation of the overheat protection circuit, of course, according to the portable gum It is possible to introduce an overheat prevention circuit into the second diameter. Therefore, according to the present invention, the overheat prevention circuit using the MITR element is provided in the lighting control panel 111a, so that a high-power LED or the like of 1W or more can be used as the lighting 111, and thus the lighting of the conventional portable otoscope is performed. There is an advantage of being free from the limitations that have been placed to increase the brightness.

As described above, according to the present invention, the brightness of the illumination can be freely increased as compared with the prior art, thereby making it easier to secure the field of view and ultimately further increasing the sharpness of the captured image.
