[Industrial applications]

 The present invention is a kind of medical electronic device, in particular, a real image red light pulse audio amblyopia treatment device for amblyopia treatment.

[0002]

[Prior art]

 Amblyopia occurs relatively often as a child's eye disease, but its pathology does not currently have a unified recognition, and from a traditional viewpoint, it is caused by the central part of the cerebrum or an external cause. As for the amblyopia, there is a lesion on the retina of the patient, so that the lesion cannot be observed by usual means. Neither of these two theories is yet definitive. It has become clear that the transmission of the human visual impulse travels through many passages due to the progress of electrophysiology technology in recent years. For example, there are blind passages that control fine analysis power and peripheral passages that separate spatial structures, that is, X passages and Y passages. When the X and Y passages are opened simultaneously, the Y passages develop a competitive inhibition on the X passages, quenching the excitement of neural tissue on the passages behind the ganglion cells of the X passages. This slows the transmission rate of visual impulses. This is called a replacement restraint competition theory. Most of the current treatments for amblyopia in children are designed solely on the principle that human retinal macular cone cells are sensitive to red light. An example of this type of amblyopia treatment device is the music red light blinking drawing amblyopia treatment device (public notice September 14, 1988) of Taiwan Patent CN872111854. The electronic drawing pen for the passage is composed of a power circuit and the like, and controls the audio circuit according to the pattern on the printed circuit on the translucent display of blinking red light depending on whether or not there is conduction between the head of the pen and the printed circuit. There was one that fulfilled the purpose of amblyopia treatment by devoting attention to the patient and observing the blinking red light after conducting the printed circuit in detail.

[0003]

[Problems to be solved by the device]

 The above conventional technique has the following drawbacks. (B) Since only the stimulation of red light on the macular pyramidal cells of red light was used, the intensity of stimulation was limited and the therapeutic effect was not improved. (B) The structure was complicated and the manufacturing cost was high. (C) A set of high-brightness flashing red light sources was used, and there was no design of a condenser lens or light-shielding table, so the power consumption was relatively large and the amount of radiation was relatively large, so the therapeutic effect was low. (D) Many control switches were required, and the operation was complicated and inconvenient to use. As described above, the conventional techniques have many drawbacks, and improvement of the amblyopia treatment device has been expected.

[0004]

[Means for Solving the Problems]

 This is a kind of real image red light pulse audio amblyopia treatment device, and based on the theory of cross inhibition competition, the body (7), the real image lens cylinder (1), the red light lens cylinder (4), and the power supply circuit element in the body (7) (15), a real image red light circuit element (16) and an audio circuit element (17). The real image light D2 (3) and the red light D3 (6) connected to the real image red light circuit element (16) are provided at the bottom of each lens barrel and stable at the front of each lens barrel. An optical lens or lens system is provided to obtain a real image, and a convex lens that adjusts the relaxation of the eye is provided at the front of the red light lens barrel.

The present invention first suppresses the Y visual pathway of the eyeball by a real image ray, and then stimulates the X visual pathway of the eyeball by a red light pulse. This increases the impulse intensity of the X visual corridor, increases the sensory input of the patient, restores the visual acuity centered on the patient's amblyopia, and fulfills the purpose of amblyopia treatment.

[0006]

[Action]

 The present invention is a kind of real image red light pulse audio amblyopia treatment device for amblyopia treatment. The present invention takes advantage of the fact that there is no shift in the real image when the light intensity generated by the real image light is sufficient, and makes the patient gaze for 45 seconds to eliminate the competition inhibition of the Y visual passage to the X visual passage, and then red again. An optical light generates a red light pulse with a wavelength of about 650 mm ±, a light intensity of about 2.5 mcd, and a frequency of about 15 HZ. At the same time, the sound circuit element produces a sound and the patient gazes for 7 minutes. The red light pulse causes the patient's optic nerve to gaze. By utilizing the X-visual passage stimulation of cells, it improves the visual acuity of the patient and fulfills the purpose of treating amblyopia.

【Example】

 Examples will be described with reference to the drawings.

Description will be made with reference to FIGS. First, as shown in FIG. 1, the red light pulse audio amblyopia treatment device of the present invention comprises a body (7), a real image lens barrel (1), and a red light lens barrel (4). Product number (8), real image lens insertion hole (10) and red light lens insertion hole (11), operation instruction light D 1 (12), power switch K1 (13) and A real image red light conversion switch K2 (14) is provided.

Next, as shown in FIG. 2, a real image red light circuit element (16) connected to the power supply circuit element (15) is provided in the body (7). The real image red light circuit element (16) includes a chattering circuit, a red light light D3 (6) circumscribing the chattering circuit, and a real image light D2 (connected to a real image red light conversion switch K2 (14) on the power supply. 3). The chattering circuit consists of a resistor R3 that adjusts the chattering frequency, a variable resistor W, a capacitor C3 and a 555 time base U1, and a red light D3 (6) is connected to the output end of U1 and a real image light D2 (3). Is a 6.3V incandescent lamp. The operating principle of this circuit is that it communicates with the power switch K 1 (13), and if the real image red light conversion switch K 2 (14) is in the position shown in the figure, the AC voltage of 220V is transformed, rectified and filtered to reach 12V. It outputs a DC voltage and turns on the operation indicating light D1 (12) and the real image light D2 (3), and the operation indicating light D1 (12) indicates that the present invention is in operation. At this time, K2-1 sets the two output terminals of the 555 time base U1 to a low potential, and the 555 time base U2 generates continuous chattering by the action of the resistor R6, the resistor R7, and the capacitor C5, and the continuous audio by the wrapper Y. After 45 seconds or 90 seconds, the actual image red light conversion switch K2 (14) is set to the other position and connected. At this time, the real image light D2 (3) goes out, the red light D3 (6) blinks, and the trumpet Y emits intermittent sound. This is because when the contact K2-1 of the real image red light conversion switch K2 (14) is turned to the other position shown in the figure and the fourth output end of the 555 time base U1 contacts the third output end of 555U1. It is caused by the alternating action of two kinds of high and low voltage. After 7 minutes, the real image red light conversion switch K2 (14) reaches the position shown in the figure. In this way, the treatment process is completed once again. When the power switch K1 (13) is turned off, the operating state of the present invention is stopped.

FIG. 3 shows a state in which the real image light D2 (3) of the present invention is installed at the bottom of the real image lens barrel (1). Two lenses for processing the light rays of the real image light D2 (3) into parallel rays are provided in the front part of the real image lens barrel (1). These two lenses employ a convex-concave lens (20) and a convex-concave lens (21) in order to reduce the spherical difference of the lenses and stabilize the real image and prevent shift. The convex-concave lens (20) has a focal length of 25.42 mm, the diameter is 10 to 20 mm, the convex-concave lens (21) has a focal length of 28.23 mm, the diameter is 10 to 20 mm, and the distance between both lenses is It is set to 2 to 8 mm.

For example, when the diameter of both lenses is 14 mm and the distance between both lenses is 3 mm, a relatively good therapeutic effect can be obtained. At this time, an opaque black spot having a diameter of 3 to 8 mm is provided at the center of the front surface of the convex-concave lens (20).

As shown in FIG. 4, in order to enhance the effect of red light treatment and avoid the fatigue caused by long-term eye-gaze of the blinking red light by the patient, the front part of the red light lens barrel (4) is used. A +3 to +10 D convex lens (19) may be added to.
