JP4194980B2 - Eye muscle training device - Google Patents

Description

The present invention relates to a training apparatus for recovering and improving visual acuity of a person whose visual acuity has deteriorated due to a decline in the function of eye muscles.

Looking at the structure of the visual acuity recovery training apparatus so far, the training is mainly in the perspective direction, and the aim is to recover the adjustment function of the ciliary muscle of the inner eye muscle among the eye muscles. In addition, during training, trainees go to a specific place where the device is installed, and training is performed in the relationship between the patient and the examiner, so there are inevitably restrictions on time, place, and usage. receive.

Japanese Patent Laid-Open No. 60-048743 JP-A-6-339501 JP 2001-61917 A

The eyeball itself does not have any special diseases other than the loss of visual acuity adjustment function, and if it is examined by an ophthalmologist, it can only be recommended for eyesight examinations and appropriate glasses, and is not treated to restore vital vision. However, no recovery policy is recommended.
If you go to a special facility these days, it is possible to get some training, but it is difficult to continue using it due to time and economic problems, or give up from the beginning. This is both the inventor's own experience and the motivation for applying for this idea.

The inventor found that stiffening of the extraocular muscles has some negative effects on visual acuity, for example, just as the muscles of the shoulders become stiff and the movement of the arms and neck may be impeded. Therefore, the following two points are given as challenges.
1. Focusing on the motor functions of the extraocular muscles (upper and lower rectus muscles, inner and outer rectus muscles, upper and lower oblique muscles) as a target for visual acuity recovery training, this also serves to relieve the stiffening of these extraocular muscles Is a training device possible?
2. Is there a device that can be used easily at home whenever you like?

  A guide bar supported by a fulcrum and capable of reciprocating on a guide bar that can be moved like a seesaw in the front vertical plane is provided. Left and right horizontal direction, 2. 2. from diagonally right up to diagonally down left and vice versa Training from the upper left to the lower right and vice versa is possible, and the pedestal can be rotated in a horizontal plane (a limit is set in the range of 90 degrees for the sake of convenience), so that the guide bar can be used appropriately. 3. In a tilted state Training up and down the line of sight.

  By these, it can be set as the training apparatus which can give a quantitative repeated exercise | movement with respect to an external eye muscle (inner / outer rectus muscle, upper / lower oblique muscle, upper / lower rectus muscle).

The above 1.-4. In the training in each direction, the ciliary muscle, which is the internal eye muscle, is also being trained at the same time , but the ciliary muscle was specifically targeted. For training in the perspective direction, the guide bar can be leveled (horizontal is not a requirement, but the expression matches the application drawing), and quantitative repetitive training is possible by following an indicator that moves back and forth from the end of the guide bar. . At this time, put your hand on the guide bar, but to prevent the risk of eyes hitting the end of the guide bar directly, place the inclined part of the nose directly on the inclined part of the end of the guide bar to make the relative movement zero. Do it.

  A small motor with a built-in reduction gear (hereinafter referred to as “motor”) capable of reversible rotation is used as the index moving drive device. There are two methods for mounting the motor: a method of mounting at a static position such as a fulcrum stand and a method of mounting directly on the side of the guide bar (dynamic position relative to the static position).

  The string that pulls the slider for attaching the indicator is preferably a thin, strong, and elastic material, and a badminton-specific string is used. As a method of attaching the string, a method of caulking and fixing the both ends of the slider side and the reel side using caulking sleeves is adopted. The string tension is obtained by combining two reels under the same rotation axis and winding them with different phases, thereby not only eliminating slack but also obtaining an appropriate tension. Even if aged loosening occurs, after removing the spring pins that determine the relative position of the two reels and winding the string around one reel to eliminate slack and provide proper tension It can be adjusted by inserting it again.

  Considering the difference in height of users, the struts of the device are structured so that the level can be adjusted.

The length of the guide bar should be less than 1m because it is tilted like a seesaw on the table, but it is possible to make the guide bar longer by making it stand-type from the floor. It is. However, the above-mentioned 1. ~ 4. In training, it seems that cost effectiveness is small even if the guide bar is lengthened. Although it may also be an effective means for training of the dynamic body eyesight, different from the spirit of the present proposal.

  Considering that the length of the guide bar is short, a thin line is put in the shape of the indicator and the guide cover surface so that people who feel that the degree of vision loss is light and cannot rely on the short length can be motivated to train.

The present invention provides a quantitative repetitive movement in almost all directions of daily eyeball movement, such as left and right, diagonal up and down, up and down and perspective directions, by tracking an indicator that reciprocates in a certain section. The eye muscle training is easy to carry out and can be carried around, so if you have a power source, you can train anytime, anywhere.

  Moreover, it can be utilized not only as a training for recovery / improvement of lowered visual acuity, but also as a training device for preventing the visual acuity of professionals who overuse their eyes.

  If this device is widely spread socially, it is expected to have a large effect on the industry.

The external view of this apparatus is shown in FIGS. The usage of this device is as follows. Left and right horizontal direction, 2. 2. from diagonally right up to diagonally down left and vice versa When performing each training from the upper left to the lower right and vice versa, the chin is placed on the cushion 57 and the guide bar 14 is arranged at a predetermined angle as shown in FIG. The index 17 is reciprocated by operating the reversing switch 71 (the operation can be automated, but is omitted in this embodiment). 4).
