Description

Technical Field

[0001] The present invention belongs to the technical field of ophthalmic examination auxiliary equipment, and in particular relates to an examination auxiliary equipment for ophthalmic treatment. Background Art

[0002] Ophthalmology is a specialized discipline that studies the occurrence, development, prevention and treatment of diseases of the human visual organs. It has strong professional characteristics, but is also widely related to other clinical disciplines and basic medical disciplines. The research scope of ophthalmology includes the physiology, biochemistry, pharmacology, pathology, immunology, genetics of the eye, as well as various special examinations of the eye and eye microsurgery techniques. Among them, the visual acuity chart is a commonly used examination auxiliary equipment in ophthalmic treatment. For example, a remotely controllable adjustable visual acuity chart proposed in the patent publication number CN104739362B.

[0003] In the current visual acuity detection process, the patient needs to stand five meters away from the visual acuity chart, use an occlusion board to cover one eye, and observe the visual acuity chart with one eye in turn. During the detection, the medical staff needs to stand beside the visual acuity chart for a long time, hold a pointer in hand and point at the visual targets one by one. The patient responds by indicating the opening direction of the visual target with a finger. When the patient can correctly identify all or most of the content in a certain row of visual targets, the visual acuity value corresponding to this row is recorded as the patient's visual acuity;

[0004] However, in the case of a large flow of ophthalmic patients, the disadvantages of this traditional detection method are obvious.

[0041] A heat dissipation opening 33 is formed in the rear side wall of the installation box 1, and a dust-proof net 12 is fixedly connected in the heat dissipation opening 33, which can discharge the heat inside the installation box 1.

[0042] The operation principle of the present invention will be described as follows: When an ophthalmic patient needs to check eyesight, the patient holds the shielding cover assembly 8 and stands at a distance of five meters from the light-transmitting plate 2, and inserts the thumb into the pointing sleeve 9, and then uses the shielding cover assembly 8 to shield one eye. Then, the medical staff sends an electrical signal to the PLC controller 6 through a remote control device. After receiving the electrical signal, the PLC controller 6 will control the screw linear module 111 to work. The screw linear module 111 drives the threaded rod moving mechanism 13, the lifting box 14 and the pointing board 15 to move downward to a set position together through the lifting plate 112 (in the initial state, the pointing board 15 is placed at a high position in the installation box 1), so that the pointing board 15 moves to the lower part of the uppermost vision board 5. Then, the PLC controller 6 controls the power motor to work, and the power motor will control the rear threaded rod moving mechanism 13 to work. At the same time, the single-slot pulley mechanism will control the front threaded rod moving mechanism 13 to work (the threaded rod moving mechanism 13 is composed of a box body, a threaded rod and a threaded barrel. The power motor controls the rotation of the threaded rod, and the threaded barrel will be controlled to move through thread cooperation, so as to control the movement of the pointing board 15 and the mounting seat 20). The front threaded rod moving mechanism 13 will drive the pointing board 15 to move to the left (in the initial state, the pointing board 15 is placed at the rightmost position). During the process of moving to the left, the pointing board 15 will drive the rear conductive block 16 to move together. During the movement of the conductive block 16, it will contact the conductive seat 17 below the uppermost vision board 5. The conductive plate is electrically connected to the PLC controller 6, and the conductive seat 17 is electrically connected to an external power supply. When the conductive block 16 contacts the conductive plate, an electrical signal will be sent to the PLC controller 6, and the PLC controller 6 will stop the power motor by control, so that the pointing board 15 stops below the vision board 5. Then, the rear threaded rod moving mechanism 13 will drive the mounting seat 20 to stay behind the circular plate 182 corresponding to the uppermost vision board 5. Then, the PLC controller 6 will control the indicator light 32 on the surface of the pointing board 15 to work. After the patient sees the indicator light 32 light up, the patient can use the thumb to point to the orientation of the vision board 5. For example, when the orientation of the vision board 5 is upward and the patient distinguishes correctly, the patient only needs to use the thumb to push the upper pointing switch 10, and the pointing switch 10 will control the upper micro electric push rod 22 to reciprocate once through the PLC controller 6 (the pointing switch 10 is connected to the PLC controller 6 through a wireless module). The micro electric push rod 22 will drive the upper pressing plate 23 to reciprocate back and forth once. Since the upper part of the corresponding circular plate 182 is a blank area at this time, the pressing plate 23 will not press the extrusion switch 19 (the relationship between the extrusion switch 19 and the orientation of the test board refers to Figure 3), indicating that the patient points correctly. After the PLC controller 6 does not receive the electrical signal transmitted from the extrusion switch 19 when the patient presses the pointing switch 10, it will drive the pointing board 15 to move to the leftmost side of the installation box 1 through the threaded rod moving mechanism 13, and control the lead screw linear module 111 to continue driving the threaded rod moving mechanism 13, the lifting box 14 and the pointing board 15 to move downward to the set position together, and guide the visual acuity board 5 in the lower row for the patient to judge;

[0043] When the patient points incorrectly during the examination, referring to the above principle, the micro electric push rod 22 will squeeze the extrusion switch 19 through the pressing plate 23, and the extrusion switch 19 will control the positioning block 25 to be electrically connected to the external power supply through the PLC controller 6. Since the threaded rod moving mechanism 13, the lifting box 14 and the pointing board 15 will move synchronously, when the pointing board 15 moves below a row of visual acuity boards 5, the lifting box 14 will drive the positioning block 25 to contact the corresponding resistance board 24. When the positioning block 25 is connected to the external power supply, the current will be transmitted to the PLC controller 6 through the positioning block 25 and the resistance board 24. Since the resistance values of the resistance boards 24 at different heights are different, when the positioning block 25 contacts different resistance boards 24, current signals of different magnitudes will be transmitted to the PLC controller 6. After receiving different current signals, the PLC controller 6 will display different numbers on the display screen 7 (the PLC controller 6 collects current signals of different magnitudes through the analog input module, converts them into digital quantities, then processes and compares these digital quantities using programming logic, determines the set number matching the current value according to the preset correspondence between current and numbers, and finally transmits this number to the display screen 7 through the communication interface, so as to present the set numbers corresponding to different magnitudes of current on the display screen 7), and the patient's vision can be displayed;

[0044] When it is necessary to adjust the orientation of the visual acuity board 5, the medical staff needs to transmit an electrical signal to the PLC controller 6 through the remote control device, and the PLC controller 6 will control the adjustment motor 31 to work. The adjustment motor 31 controls multiple rotating rods 181 to rotate together through the double-groove pulley mechanism, and the rotating rods 181 will drive the visual acuity board 5 and the circular plate 182 to rotate to the set angle, thus avoiding the problem that the orientation of the visual acuity board 5 is memorized by the patients during the follow-up visit and affecting the patient's vision examination;

[0045] When it is necessary to clean the dust on the surface of the light-transmitting plate 2, the medical staff sends an electrical signal to the PLC controller 6, and the PLC controller 6 will control the lead screw linear module 111 and the air pump 262 to work simultaneously for one minute. The lead screw linear module 111 drives the front side threaded rod moving mechanism 13 and the lower dust cleaning pipe 27 to move up and down through the lifting plate 112, and uses the brush hairs 29 on the surface of the dust cleaning pipe 27 to clean the dust attached to the surface of the light-transmitting plate 2. The cleaned dust will be transported to the dust cleaning box 261 for storage through the air inlet head 28 and the collection pipe 30.

[0046] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
