DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, an embodiment of the utility model provides an auxiliary device for lacrimal duct flushing, including a support plate 1 and a transverse plate 2. The transverse plate 2 slides transversely on the surface of the support plate 1. Both sides of the inner wall of the transverse plate 2 are fixedly connected to limit blocks 21. The two limit blocks 21 are slidably connected to the opposite sides with pull plates 22. A limit groove is provided in the limit block 21. The pull plate 22 slides in the limit groove. An enlargement disk 33 for enlarging the eye area is provided on one side of the transverse plate 2. A plurality of lighting lamps B333 are fixedly connected to the bottom of the enlargement disk 33. The lighting lamps B333 are circumferentially arranged at the bottom of the enlargement disk 33, and the lighting lamps B333 are soft light lamps. A lighting lamp A213 is fixedly connected to the bottom of the limit block 21 close to the side of the enlargement disk 33. The lighting lamp A213 is also It is a soft light to avoid strong stimulation to the patient's eyes. A lens 332 is fixedly connected to the inner wall of the magnifying disk 33. The lens 332 is a magnifying glass with a certain magnification. The specific magnification is selected according to different patients and doctors. A fixed plate 3 is fixedly connected to one side of the horizontal plate 2. A rotating block 32 is rotatably connected to the surface of the fixed plate 3. The rotating block 32 is connected to the magnifying disk 33 through a movable component. The rotating block 32 is also connected to the pull plate 22 through a pull rope 221, and the pull rope 221 is passed through the fixed plate 3. A switching component for switching between the lighting lamp A213 and the lighting lamp B333 is provided in the limit block 21 close to one side of the magnifying disk 33. A pressing component for moving the pull plate 22 downward is installed on the surface of the support plate 1.

[0023] Specifically, by pressing down the pressing component, the pull plate 22 is driven to move downward, and then the rotating block 32 is pulled by the pull rope 221, so that the rotating block 32 drives the magnifying disk 33 to rotate between the doctor's eyes and the patient's eyes, thereby magnifying the patient's eyes and facilitating the doctor's magnified observation operation. In addition, by respectively providing independent lighting lamps A213 and lighting lamps B333 under the magnifying disk 33 and the limit block 21, through the switching component, when the magnifying disk 33 is used, the lighting lamp B333 is lit, and when the magnifying disk 33 is not used, the lighting lamp A213 is lit, so as to prevent the lighting source from moving with the magnifying disk 33 and affecting the lighting effect.

[0024] like Figure 4 As shown, in this embodiment, the switching component includes a trigger button A211 and a trigger button B212 respectively installed on the top and bottom of the inner wall of the limit block 21, the trigger button A211 is electrically connected to the lighting lamp A213, the trigger button B212 is electrically connected to the lighting lamp B333, and the lighting lamps A213 and B333 are both connected to an external power supply and powered by the external power supply.

[0025] Specifically, by moving the pull plate 22 up and down, it touches and presses the trigger button A211 and the trigger button B212 respectively. When the pull plate 22 moves up and presses the trigger button A211, the lighting lamp A213 will be turned on. At this time, the magnifying plate 33 is in a removed state, and the lighting lamp B333 under the magnifying plate 33 is off, so as to avoid the synchronous movement of the light source caused by the movement of the magnifying plate 33, thereby affecting the illumination of the eyes. In addition, when the pull plate 22 moves down and presses the trigger button B212, the trigger button A211 is not pressed, so the lighting lamp A213 will be off, and the lighting lamp B333 will be on. At this time, the magnifying plate 33 will be pulled by the pull rope 221 to rotate to the working position, thereby facilitating the circumferential soft light illumination of the magnifying plate 33.

[0026] Furthermore, the upper and lower surfaces of the fixed plate 3 are fixedly connected with a fixed rod 31, and the fixed rod 31 is inserted into the rotating block 32. The rotating block 32 can rotate around the fixed rod 31 as the axis, thereby rotating to be close to the horizontal plate 2 or away from the horizontal plate 2.

[0027] Furthermore, the fixed rod 31 is connected to the rotating block 32 through a torsion spring 311, and the two ends of the torsion spring 311 are fixedly connected to the fixed rod 31 and the rotating block 32 respectively. When the torsion spring 311 is in a normally relaxed state, the enlarging disk 33 is in a position away from the horizontal plate 2. When the pull plate 22 moves downward and drives the pull rope 221 to pull the rotating block 32 to rotate, the torsion spring 311 will be compressed. Therefore, after the pull plate 22 moves up, the torsion spring 311 rebounds and drives the rotating block 32 back to its initial position.

[0028] like Figure 4 and Figure 5As shown, in this embodiment, the movable component includes a connecting ball 331 fixedly connected to the surface of the magnifying disk 33, and a connecting seat adapted to the connecting ball 331 is installed on the surface of the rotating block 32. The connecting ball 331 and the connecting seat form a universal ball joint, so it is convenient to adjust the pointing position of the magnifying disk 33, and because the lighting lamp B333 is set at the bottom of the magnifying disk 33, when the angle of the magnifying disk 33 is adjusted, the lighting position is always synchronized with the magnifying disk 33.

[0029] like Figure 3 As shown, in the present embodiment, the pressing assembly includes a connecting rod 4, a square hole is opened in the support plate 1, the connecting rod 4 slides in the square hole, the connecting rod 4 slides up and down in the square hole, the lower end of the connecting rod 4 is connected to the support plate 1 through a spring 42, the two ends of the spring 42 are respectively fixedly connected to the connecting rod 4 and the support plate 1, the upper end of the connecting rod 4 is fixedly connected with a sliding block 43, and the pull plate 22 is penetrated in the sliding block 43, so that when the connecting rod 4 moves downward, the spring 42 will be compressed, and further, the sliding block 43 will drive the pull plate 22 to move downward, thereby completing the pulling-down operation of the pull plate 22, and at the same time, because the pull plate 22 slides in the sliding block 43, when the cross plate 2 slides on the support plate 1 as a whole, the pull plate 22 will also slide synchronously in the sliding block 43.

[0030] Furthermore, a pressing plate 41 is fixedly connected to the lower end of the connecting rod 4, and the pressing plate 41 is convenient for the doctor to press with his feet to move the connecting rod 4 downward.

[0031] The lower end of the support plate 1 is rotatably connected to the base 11 , so that the support plate 1 can be rotated on the base 11 , so as to facilitate adjustment of the pointing angle of the horizontal plate 2 .

[0032] Working principle:

[0033] When the tear duct is flushed and lighting and magnification are needed, the device is placed on one side of the bed and the base 11 is placed on a flat ground for support. Then the support plate 1 is rotated and the angle of the horizontal plate 2 and the magnifying plate 33 on its surface are adjusted to above the patient's eyes. At this time, the doctor can perform normal tear duct flushing operations. When it is necessary to magnify and observe the patient's eyes, there is no need to stop the manual operation. Just step on the pressure plate 41 to drive the connecting rod 4 to move downward and compress the spring 42. At the same time, the sliding block 43 will also pull down the pull plate 22, so that the pull plate 22 slides down in the limit block 21 until it slides to the bottom of the limit groove, and press the trigger button B212 to turn on the lighting lamp B333. In this process, due to the pull The downward movement of the plate 22 will synchronously pull the pull rope 221, and then pull the rotating block 32, causing it to rotate toward the side close to the horizontal plate 2, and compress the torsion spring 311. The magnifying disk 33 will synchronously follow the rotating block 32 to rotate toward the side close to the horizontal plate 2, thereby facilitating the doctor's observation. When magnified observation is not required, the doctor does not need to stop the operation at hand. The doctor only needs to move his foot away from the stepping plate 41, and then push the connecting rod 4 upward under the action of the rebound force of the spring 42, and then push the pull plate 22 upward. The torsion spring 311 rebounds synchronously, driving the rotating block 32 to rotate and rotate the magnifying disk 33 to one side. At this time, the pull plate 22 presses the trigger button A211, and the lighting lamp A213 lights up, while the lighting lamp B333 goes out.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
