Ophthalmoscope with reflector

The present invention relates to an ophthalmoscope having a reflector capable of optometry while maintaining a correct posture by a doctor by adjusting the angle of an examination light path according to the position of a patient.

In general, an ophthalmoscope designed to look inside the eye is used to examine the image of the retina with light reflected from the retina by shining light on the pupil in a dark room. It is essential for the diagnosis of retinal disease, which is the most common cause of blindness in current eye diseases.

As such, an ophthalmoscope is a medical device that can see the retina of the eye, and the retina is a part that recognizes light through the retina at the back of the eye. An indirect ophthalmoscope consists of a light source, an alternative lens, and a head fixing device. When the light from the light source enters the patient's eye and then bounces back, the ophthalmoscope passes through the alternative lens of the iconographic ophthalmoscope and enters the examiner's eye to see the patient's retina.

The iconographic ophthalmoscope according to the prior art can be used only when the patient's eye is placed in front of a medical professional. When the patient is sitting, the examiner also sits and examines while looking straight, so there is no big inconvenience. However, referring to FIG. 1, when the subject is located in the lower direction of the examiner, such as when the patient 3 is lying down, such as an infant or an elderly person, the examiner 2 should be tested in an unstable state because the examiner 2 must bow his head to 90 degrees. And, in the case of a long time inspection, there is a problem in that the fatigue of the inspector 2 is increased, such as a strain on the neck of the inspector 2 by the weight of the ophthalmoscope 1 itself.

It is an object of the present invention to solve such a problem, and to provide an ophthalmoscope having a reflector that enables optometry for a patient while maintaining a correct posture by adjusting the angle of an examination light path corresponding to the position of the object to be examined.

Hereinafter, an ophthalmoscope 100 having a reflector according to an embodiment of the present invention will be described in more detail with reference to the drawings.

First, referring to FIG. 2, a state in which the doctor 2 examines the patient 3 while wearing the ophthalmoscope 100 according to an aspect of the present invention is shown. As shown, since the doctor 2 wears the ophthalmoscope 100 and does not bend the neck, it is possible to have a medical examination, so that an optometry can be performed in a posture that does not cause excessive stress for a long time.

The ophthalmoscope 100 having a reflector according to an embodiment of the present invention includes a main body 110 and a reflector 230.

2 to 7, the main body 110 is mounted to be supported on a part of the body of the doctor so that the doctor can examine the retina of the patient, and a pair of eyepieces 111 positioned in front of both eyes respectively. ), the light reflected from the patient's retina is observed and an optometry is performed.

The main body 110 is mounted and fixed to the head rest 10, referring to FIGS. 4 to 7. Therefore, the doctor fixes the head rest 10 to the head and performs optometry.

At this time, the headrest 10 is composed of a horizontal band 11 and a vertical band 12, and is designed to be tightened or released using

knobs

11a and 12a, respectively. Accordingly, the doctor may properly fix the headrest 10 by tightening or loosening the

knobs

11a and 12a according to the size of the body.

In this case, a vertical rotation shaft 112 is installed in the front center of the headrest 10, and the main body 110 is installed at a lower end of the vertical rotation shaft 112.

At this time, since the main body 110 is installed on the vertical rotation shaft 112, the angle can be adjusted according to the doctor's choice.

At this time, a pair of eyepieces 111 are provided at the rear of the main body 110 so that a doctor performs an examination through each eyepiece 111 during optometry. One ophthalmological window 113 is formed in front of the main body 110. Therefore, during optometry, the image seen from the retina passes through the ophthalmic window 113 and then passes through internal reflectors (not shown), and then passes through the pair of eyepieces 111, and the doctor turns the image into both eyes. It will be examined and examined.

At this time, the main body 110 has a shape in which the ophthalmic window 113 protrudes, and an assembly groove 110a for assembling the reflector 230 is formed on both sides of the protruding portion.

Referring to FIGS. 2 to 7, the reflector 230 may be assembled outside the main body 110 so that the retinal image of the patient incident on the pair of eyepieces 111 is reflected at a predetermined angle.

In this case, the reflector 230 is assembled to be rotatable with respect to the main body 110 so that the reflection angle can be adjusted.

In this case, the reflector 230 may be rotatably assembled to the frame 210 for assembling the reflector 230 to the main body 110. In this case, the frame may be formed to have a rectangular shape, but the shape of the frame is not limited thereto.

At this time, the frame 210 is opened in the center and may be assembled to the main body 110. At this time, the rotating shaft 220 is rotatably assembled to the frame 210, and the reflector 230 may be rotatably assembled to the rotating shaft 220 on the front of the frame 210.

In this case, a pair of legs 212 protruding rearward may be formed on the frame 210. An assembly protrusion 212a is formed on each of the pair of legs 212, and the assembly protrusion 212a may be inserted into and assembled into an assembly groove 110a formed in the main body 110. Conversely, a groove portion is formed in the pair of legs 212 and a protrusion portion is formed in the body 110 so that the leg may be coupled to the groove portion.

At this time, when assembling to the main body 110 of the frame 210, the pair of legs 212 are separated by the thickness of the assembly protrusion 212a, and then the assembly protrusion 212a is When assembled by being inserted into the assembly groove (110a) can be returned to the original position.

At this time, the frame 210 is formed with a bearing part 211 into which the rotating shaft 220 is rotatably inserted, and a pair of rotating ring parts 231 into which the rotating shaft 220 is inserted into the reflector 230 as well. ) Can be formed.

The pair of rotation ring portions 231 are assembled to be in close contact with both ends of the bearing portion 211, the bearing portion 211 and the rotation ring portion 231 so that the reflector 230 can be fixed only at a certain angle. ) Teeth (211a, 231,) may be formed on the contact surface, respectively.

Referring to FIG. 3, the ophthalmoscope body 110 is mounted in the front center of the headrest 10, and the reflector 230 is installed to be rotatable in front of the ophthalmic window 113 of the body 110. Here, a state in which the reflector 230 is completely rotated upward is shown.

The main body 110 is also designed to be able to slightly adjust the rotation angle with respect to the head rest 10, so that the doctor can adjust it according to himself. In a normal case, optometry is performed without using the reflector 230 as shown in FIG. 3. That is, when both the doctor and the patient are sitting, the doctor does not use the reflector 230 and performs an optometry as in a normal case.

4, the assembly structure of the main body 110 and the reflector 230 is shown in an exploded perspective view. The reflector 230 may be assembled so that the frame 210 can be rotated through the rotation shaft 220.

To this end, the main body 110 may have assembly grooves (110a) formed on both sides, and the frame 210 on which the reflector 230 is installed has legs 212 formed on both sides of the rear, each end Assembly can be completed when the assembly protrusion 212a is formed inward so that the assembly protrusion 212a is inserted into the assembly groove 110a.

Of course, when assembling, the gaps between the legs 212 are elastically opened, and then elastically returned after assembly to complete the assembly.

Referring to FIG. 5, an assembly structure of a reflector assembly 200 including a reflector 230 is shown. The reflector 230 is rotatably assembled to the frame 210 via the rotation shaft 220.

The reflector 230 is provided with a rotation ring 231 and a bearing part 211 is formed on the frame 210, so that when the rotation shaft 220 passes through all of them and is assembled, the assembly of the reflector assembly 200 can be completed. have.

In the case of the reflector 230, since it is difficult to form the rotating ring part 231, a shape having the rotating ring part 231 may be made of synthetic resin or the like, and then the reflecting mirror may be adhered to the inside thereof.

In addition, the frame 210 may be formed in a frame shape through which the central hole 210a is penetrated, the pair of legs 212 may be formed at the rear, and a bearing part 211 may be formed at the upper part.

The rotation shaft 220 is assembled in a bolt and nut manner, and a head 221 is formed in a handle shape on the rotation shaft 220 constituting the bolt portion, and the nut 222 on the opposite side may also be formed in a handle shape.

Accordingly, it is possible to assemble by inserting the rotation shaft 220 in a state in which the rotation ring part 231 and the bearing part 211 are aligned.

After assembly, wave-shaped

teeth

211a and 231a are formed on the surface in close contact with the rotating ring part 231 and the bearing part 211, and when the reflector 230 is held and turned by hand, the meshing teeth are changed into adjacent teeth. The rotation angle is determined and can be fixed in that state. Accordingly, the rotation angle of the reflector 230 can be arbitrarily adjusted according to the user's selection.

Referring to the side view shown in FIG. 6, it is shown that the rotation angle of the reflector 230 can be arbitrarily adjusted within an angle of about 180 degrees according to a doctor's choice. In normal cases, the optometry is performed while the reflector is rotated completely upward, as in the part indicated by the dotted line, but there are cases where the optometry must be performed in a lying state for reasons of circumstances when the patient is an infant or the patient's body is uncomfortable.

In this case, if the doctor adjusts the angle of the reflector 230 to suit him and then proceeds with the optometry, the doctor may proceed with the optometry in the correct posture without bending a part of the body such as the neck or waist. In particular, in the case of long-term optometry, it would be desirable to use a reflector.

Referring to FIG. 7, it is shown that the reflector 230 can be adjusted and fixed at a desired angle.

The reflector 230 is formed on the rotation ring part 231 and the bearing part 211 to determine and maintain the angle according to the tooth position at which the wave-shaped

teeth

211a and 231a mesh with each other.

Here, a wave-shaped tooth shape was applied as a means to fix the angle at each arbitrary angle, but a means of dividing the axis of rotation into both sides and pulling each other with tension with an elastic body to fix the angle by frictional force can also be considered. There will be. Of course, in addition to these angle adjustment means, applicable mechanical means may be considered.

Although an embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiment presented in the present specification, and those skilled in the art who understand the spirit of the present invention can add components within the scope of the same idea. It will be possible to easily propose other embodiments by changing, deleting, adding, etc., but it will be said that this is also within the scope of the present invention.

The ophthalmoscope according to an embodiment of the present invention may be used for medical purposes in ophthalmology.
