In the figure: the measuring device comprises a handle 1, a battery cover 2, a lampshade 3, a light filter 4, a switch 5, a measuring plate 6, a sliding chute 7, scales 8, a supporting frame 9, a cushion 10, a nose bridge bracket 11, a loop bar 12, a telescopic rod 13, a sliding rod 14, a limiting plate 15, a pointer 16, a light screen 17, a fixing plate 18, a reflecting plate 19 and a light source 20.

Detailed Description

As shown in fig. 1-3, a flashlight for measuring pupil size includes a handle 1, a battery cover 2, a lampshade 3, and a switch 5, the bottom of the handle 1 is provided with the battery cover 2, the handle 1 is provided with a loop bar 12 of the switch 5, the top of the handle 1 is provided with the lampshade 3, one end of the loop bar 12 away from the handle 1 is sleeved with one end of a telescopic rod 13, the other end of the telescopic rod 13 is connected with a limiting plate 15 through a sliding rod 14, the sliding rod 14 is sleeved with a measuring plate 6, the measuring plate 6 is provided with a sliding chute 7 and a scale 8 which are matched with the sliding rod 14, the measuring plate 6 is provided with a supporting frame 9, the lampshade 3 is provided with a reflecting plate 19 and a light source 20, and the lampshade 3 is.

In a preferred scheme, the top of the supporting frame 9 is provided with a cushion 10. The comfort level of the patient when the supporting frame 9 is supported on the eye socket of the patient is guaranteed, and the practicability is high.

In a preferred scheme, a nose bridge bracket 11 is arranged on the supporting frame 9. The supporting frame 9 is convenient to position, the supporting position is quickly determined, and the working efficiency is improved.

In a preferred embodiment, the light shielding plate 17 is a circular plate, and the center of the light shielding plate 17 and the center of the light source 20 are on the same vertical axis. The shading effect of the shading plate 17 is ensured, and the measurement of the pupil diameter is convenient.

In a preferred embodiment, the optical filters 4 are disposed between two of the fixing plates 18. Avoid light source 20's light to produce great stimulation to patient's eyes, also can avoid impurity to fall into lamp shade 3 when making light softer, influence the illumination effect.
