Description

 TECHNICAL FIELD

 The invention relates to a device for treating myopia, in particular to a device for treating binocular optical magnetic myopia. Background technique

 Eye refractive error, especially the number of eyes with nearsightedness among adolescents, has become a very serious problem. Many ophthalmologists and people of insight have proposed various solutions for the treatment of myopia in adolescents, including medical and physical therapy solutions. Among them, the Chinese patent application 92101546.1 filed by the applicant on March 13, 1992 discloses an electromagnetic light myopia physiotherapy device. During physiotherapy, the treated eye gazes from near to far through the observation tube of the device, and then the far and near images force the treated eye to focus continuously, while the ciliary muscles are repeatedly exercised, and the observation ring is naturally compressed. Eyeballs make the shape of the eyeballs change under pressure at various points, thereby improving vision. The device also includes an electric therapy device and a magnetic therapy device. The electric stimulation of a specific acupuncture point and the magnetic therapy effect produced by the magnetic field lines of the constant magnetic field realize the mutually coordinated therapy of electromagnetic light. Practice over the years has proven that the above device has a certain physiotherapy effect. However, it was also found that the device is a monocular treatment. Although the treatment time for one eye is not too long, it is difficult to persist because the treated person is a child about ten years old. On the other hand, patients are almost always myopic. Therefore, after treating one eye, it is necessary to treat the other eye, which will take longer. Summary of the Invention

 Therefore, an object of the present invention is to provide a binocular photomagnetic myopic physiotherapy device.

 Referring now to Figs. 1 and 1, the image device 30 placed in front of the binocular visual observation device 10 will be described. The image device 30 is mounted on a control device 50 that controls its reciprocating movement in the direction of the longitudinal axis of the binocular visual observation device 10. The image device 30 includes a post 31 with one end connected to the control device 50 and the other end connected to the image device holder 32. The image device holder 32 is installed therein. The lighting device includes a light source 33. 34, the rear of the light source 33 may be provided with a reflection Device 35 to make full use of the light emitted by the light source 33. The image device base 32 has an image frame 36 at the front end, which contains two identical or different images 37 and 38, and the center of each image is located on the optical axis of the observation tubes 11 and 11 '.

The control device 50 controls the image device 30 along the longitudinal axis of the binocular visual observation system 10 to The range of the return motion is the distance between the far and near points of the human eye. As shown in FIGS. 1 and 2, the control device 50 includes a driving motor 51, an output shaft of the driving motor is connected to a crank 52, the other end of the crank is connected to one end of a connecting rod 53, and the other end of the connecting rod 53 is connected to a slider One end of 54 is connected, and the other end is connected to the post 31 of the image device 30, thereby forming a curved groove sliding mechanism. The upper side of the slider is integrated with the image device 30 through a column 31 of the image device. The sliding guide 55 passes through the slider 54, and two ends of the guide 55 are respectively fixed on the guide rail supports 56 and 57, and the supports 56 and 57 are respectively fixed on the base plate 1. A slide switch (not shown) is mounted on the slide rail 55 to control the stroke and direction change. Of course, other methods known to those skilled in the art can also be used for stroke and reversing control.

 Referring now to Fig. 3, another embodiment of a control device that produces a visual effect from near and near and near and far when the image of the image device is viewed through a binocular visual observation device will be described. This embodiment is different from the control device shown in Figs. The embodiment shown in Figs. 1 and 2 is that the control device 50 controls the movement of the image device 30, and the binocular visual observation device 10 is fixed, thereby producing the observation effect from near to far and from far to near. This embodiment is realized by keeping the image device stationary, and the objective lens barrels 25 and 25 'in the two observation tubes 11 and 11' of the binocular visual observation device 10 are moved in the tube.

Referring to FIG. 3, the control device 15G of this embodiment includes a motor 151 mounted on the base plate 1. The output shaft of the motor 151 is connected to a screw 152, and the other end of the screw 152 is connected to a rolling shaft (not shown). The bearing is fixed on the bracket 153 fixed to the base plate 1. The screw rod 152 has a nut 154, and the nut has slots 26 and 26 'passing through the observation barrels 11 and 11', respectively, and is connected to the objective lens barrels 25 and 25. 'On the connecting rods 155 and 155'. Therefore, when the motor 151 rotates, it moves along the grooves 26 and 26 'with the lens barrels 25 and 25' through the screw rod 152, the nut 154, the connecting rods 155 and 155 '. The range of movement of the objective lens barrels 25 and 25 'depends on the distance between the near and far points of the eye. When the objective lens barrels 25 and 25 'are moved to the near-point or far-point position, the change in the direction of control of the movement of the objective lens barrels 25 and 25' may be achieved by a travel switch or other methods known to those skilled in the art. Next, another embodiment of the image device will be described with reference to Figs. The image device 30 in FIGS. 1 and 2 contains only a pair of images 37 and 38, that is, according to the embodiment shown in FIGS. 1 and 1, the image observed by the patient cannot be changed. In this implementation, at least two pairs of images can be alternately viewed by the patient.

 Therefore, according to the image device 130 of this embodiment, the device includes an image device base 132 connected to a mounting plate 143 through a post 131, which houses the illumination with an illumination source according to the embodiment shown in FIG. 1 and FIG. The device 134, the lighting device may further include a reflector which fully utilizes light emitted from the light source. The image device base 132 also has an image base according to the embodiment shown in FIGS. 1 and 2. The image base is a sandwich frame 136, and a carrier 139 with an image, such as a film, can be removed from the frame. Interlayer passes. The image device 130 also includes a device for driving a carrier with an image. The device includes a driving motor 140 mounted under the mounting plate 143, and an output shaft thereof passes through a bearing 144 on the mounting plate 143 and is in contact with the carrier driving wheel 141 Then, the transmission wheels 142 are respectively fixed to the bearings 145 on the mounting plate 143. There are at least two transmission wheels 142. The carrier driving wheel 141 and the conveying wheel 142 have teeth, and the tooth moment is the same as the tooth pitch on the film. And a device (not shown) for controlling the moving distance of the carrier 139, the device may be a position switch, or other devices known to those skilled in the art.

 According to this embodiment, when the patient sees or wants to change a pair of images, as long as the motor 131 is given a signal, the motor 131 works and drives a carrier driving wheel 141 connected to it. Since the carrier 139 used is a film, The perforations are the same as those of the driving wheel 141 and the conveying wheel 142, so that the film moves around the conveying wheel 142 (three shown in FIG. 5). When the film is turned to a certain position, the required movement is achieved Distance, at this time a pair of new images will replace the original pair of images at the observation position required by the patient to observe the device 10 with the naked eye. At this time, the travel switch or similar device stops the motor 131, and the patient can view them. Observe until the next pair of images is changed.

The applicant has described the concept of the present invention and its embodiments in detail. The technician can make various improvements and changes on this basis, but these improvements and changes do not depart from the spirit of the present invention and are all within the protection scope defined by the claims.
