Description

[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 connected with other clinical disciplines and basic medical disciplines. The scope of ophthalmology research includes eye physiology, biochemistry, pharmacology, pathology, immunology, genetics, and various special eye examinations and eye microsurgery techniques. Among them, the eye chart is a commonly used examination auxiliary equipment in ophthalmic treatment. For example, a remote-controlled adjustable eye chart is proposed in patent announcement number CN104739362B.

[0003] In the current vision test process, patients need to stand five meters away from the vision chart, cover one eye with a mask, and observe the vision chart with one eye in turn.

[0024] The operating principle of the present invention is now described as follows: when an ophthalmic patient needs to check his vision, 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 of the eyes. Then, the medical staff transmits an electrical signal to the PLC controller 6 through the remote control device. After receiving the electrical signal, the PLC controller 6 controls the screw rod linear module 111 to work, and the screw rod linear module 111 drives the threaded rod moving mechanism 13, the lifting box 14 and the finger plate 15 to move downward to the set position through the lifting plate 112 (the finger plate 15 is in the installation box 1 in the initial state). ), so that the point finger plate 15 moves to the bottom of the top sight mark plate 5, and then the PLC controller 6 controls the power motor to work, and the power motor controls the rear threaded rod moving mechanism 13 to work. At the same time, the single-groove pulley mechanism is used to 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 controls the movement of the threaded barrel through thread matching, thereby controlling the movement of the point finger plate 15 and the mounting seat 20). The front threaded rod moving mechanism 13 drives the point finger plate 15 to move to the left (the point finger plate 15 is placed at the rightmost position in the initial state). The point finger plate 15 is In the process of moving to the left, the conductive block 16 on the rear side will be driven to move together. The conductive block 16 will contact the conductive seat 17 below the top sight plate 5 during the movement. The conductive plate is electrically connected to the PLC controller 6, and the conductive seat 17 is electrically connected to the external power supply. When the conductive block 16 contacts the conductive plate, an electrical signal will be transmitted to the PLC controller 6, and the PLC controller 6 will stop working by controlling the power motor, so that the point finger plate 15 will stay below the sight plate 5, and the threaded rod moving mechanism 13 on the rear side will drive the mounting seat 20 to stay behind the circular plate 182 corresponding to the top sight plate 5, and then the PLC controller 6 will control the indication on the surface of the point finger plate 15. The light 32 works. After the patient sees the indicator light 32 light up, he can use his thumb to point to the direction of the sight mark plate 5. For example, if the direction of the sight mark plate 5 is upward and the patient correctly distinguishes it, the patient only needs to use his thumb to push the upper directional switch 10, and the directional switch 10 will control the upper micro-electric push rod 22 to reciprocate once through the PLC controller 6 (the directional switch 10 is connected to the PLC controller 6 through the wireless module), and the micro-electric push rod 22 will drive the upper pressure plate 23 to reciprocate once. Since the corresponding circular plate 182 is a blank area at this time, the pressure plate 23 will not press the squeeze switch 19 (the direction relationship between the squeeze switch 19 and the test mark plate is shown in FIG. 1). Figure 3), indicating that the patient is pointing correctly, after the patient presses the pointing switch 10 and does not receive the electrical signal transmitted from the squeezing switch 19, the PLC controller 6 will drive the finger plate 15 to move to the leftmost side of the installation box 1 through the threaded rod moving mechanism 13, and control the screw linear module 111 to continue to drive the threaded rod moving mechanism 13, the lifting box 14 and the finger plate 15 to move downward to the set position, and guide the sight mark plate 5 in the lower row, and the patient will make a judgment; When the patient points to the wrong direction during the examination, referring to the above principle, the micro-electric push rod 22 will be squeezed to the squeezing switch 19 through the pressure plate 23, and the squeezing 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 finger plate 15 will move synchronously, when the finger plate 15 moves under a horizontal row of sight mark plates 5, the lifting box 14 will drive the positioning block 25 to contact the corresponding resistor plate 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 resistor plate 24. Since the resistance values ​​of the resistor plates 24 at different heights are different, the positioning block 25 contacts with different resistor plates 24, and current signals of different magnitudes are transmitted to the PLC controller 6. After receiving different current signals, the PLC controller 6 displays different numbers through the display screen 7 (the PLC controller 6 collects current signals of different magnitudes through the analog input module, converts them into digital quantities, and then processes and compares these digital quantities using programming logic, determines the set number matching the current value according to the preset current-digit correspondence, and finally transmits the number to the display screen 7 through the communication interface, so that the set number corresponding to the current of different magnitudes is presented on the display screen 7), which can display the patient's vision; When the direction of the sight board 5 needs to be adjusted, the medical staff needs to send 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, and the adjustment motor 31 controls the multiple rotating rods 181 to rotate together through the double-groove pulley mechanism, and the rotating rods 181 will drive the sight board 5 and the circular plate 182 to rotate to the set angle, thereby avoiding the problem that the patient who returns for a visit remembers the direction of the sight board 5 and affects the patient's vision examination; When it is necessary to clean 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 screw linear module 111 and the air pump 262 to work simultaneously for one minute, and the screw linear module 111 drives the front threaded rod moving mechanism 13 and the cleaning pipe 27 below to move up and down through the lifting plate 112, and the bristles 29 on the surface of the cleaning pipe 27 are used to clean the dust attached to the surface of the light-transmitting plate 2, and the cleaned dust will be transported to the cleaning box 261 through the air inlet head 28 and the collection pipe 30 for storage.
