Preferably, the strap is made of rubber elastic material.

Preferably, the slider is specifically made of transparent plastic material.

Preferably, the connecting rod is connected to the measuring ruler through a connecting bolt.

Preferably, the surface of the measurement hole is provided with a one-way light-transmitting film.

Preferably, the surface of the fixing groove is provided with anti-skid rubber.

The beneficial effects of the utility model: the precise interpupillary distance measurement is carried out through the measuring hole, and the patient will not be visually burdened, so that the patient's measurement experience is more comfortable, not only can measure the distance between two pupils, but also It can measure the diameter of a single pupil and has high applicability. After the patient wears the device, his eyes look forward, and the doctor can see the position of the patient's pupil from the measurement hole. After moving the slider to drive the measurement pointer to move, when the pointer Accurate parameters can be recorded after moving to the center of the pupil, making the measurement process accurate and simple. The slider is made of transparent plastic material to ensure the movement performance while not blocking the scale above the measuring ruler. Through the set strap It is convenient for the patient to wear the device. The strap is made of rubber elastic material, which can adapt to patients with different head circumferences and make the patient feel more comfortable. The stability performance is more obvious. The connecting rod can effectively connect the eyepiece and the measuring ruler, making the connection more stable. The surface of the measuring hole is equipped with a one-way light-transmitting film. The patient cannot see the outside world, and the doctor can see the inside from the outside, which can effectively Avoid the influence of the doctor's measurement operation on the patient's line of sight, and effectively avoid the problem of inaccurate measurement results caused by the patient's unstable line of sight. The surface of the fixing groove is equipped with non-slip rubber, which can increase the friction between the device and the patient's nose bridge, making the device The fixation is more firm, and the rubber material has a certain degree of softness, which can make the patient feel more comfortable in use.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to Figures 1-3, an easy-to-operate medical pupillary distance measuring device includes an eyepiece 1, a measuring hole 2, a measuring pointer 3, a slider 4, a connecting rod 5, a connecting bolt 6, a scale 7, a fixing groove 8, a measuring A ruler 9 and a strap 10, the surface of the eyepiece 1 is provided with a measuring hole 2, the two sides of the eyepiece 1 are provided with a connecting rod 5, the lower side of the connecting rod 5 is connected with a measuring ruler 9, and the upper side of the measuring ruler 9 is arranged There is a scale 7, the upper side of the scale 7 is provided with a slider 4, the upper side of the slider 4 is provided with a measuring pointer 3, the lower side of the measuring ruler 9 is provided with a fixing groove 8, and the two sides of the eyepiece 1 are connected with Straps10.

Working principle: After the patient wears the device, the eyes look forward, and the doctor can see the position of the patient's pupil from the measuring hole 2.
