In addition, the technical features described above in the different embodiments of the present utility model may be combined with each other as long as they do not collide with each other.

The present utility model provides a pupillary mirror as shown in figures 1, 2, 3, 4 and 5, which can be worn on the eye of a patient for measuring the size of the patient's pupil. The main structure comprises a disc-shaped pupil lens body 1, a pupil measuring assembly 2 is arranged on the pupil lens body 1, the pupil measuring assembly 2 comprises a scale 21 and a plurality of pupil measuring alignment rings 22 with different sizes, the pupil measuring alignment rings 22 are annular marks, the central points of the pupil measuring alignment rings 22 are mutually overlapped, and the scale 21 is used for marking the size of the pupil measuring alignment rings 22. It should be noted that, in order to reduce the interference of the pupil measuring assembly 2 with the patient's vision, the pupil measuring alignment ring 22 is outlined with a thin line, and in some embodiments may be outlined with a dashed line. Pupil measurement alignment ring 22 may be in a pattern other than the circular pattern described above, as shown in fig. 2, so long as alignment and pupil calibration are achieved.

The pupil measuring assembly 2 (a graduated scale 21 and a plurality of pupil measuring alignment rings 22 with different sizes) is arranged on the pupil mirror. In use, the pupillary lens is worn over the patient's eye with the pupillary measurement registering ring 22 aligned with the patient's pupil, the pupillary measurement registering ring 22 aligned with the patient's pupil being the size of the current pupil. And the current pupil measurement alignment ring 22 size is marked by the scale 21. Pupil size measurements were made in this way. Clinically, when a doctor wants to obtain the pupil size data of a patient, the pupil measurement alignment ring 22 and the graduated scale 21 can be observed through a magnifying glass at any time. After the doctor finishes measuring the pupil size data of the time, the pupil mirror on the eyes of the patient does not need to be taken down, the next measurement can be directly carried out, and the doctor can obtain measurement data in the whole measurement process. Thereby evaluating the intracranial condition of the patient.

Further, as shown in fig. 5, the pupil lens body 1 includes an inner lens 11, a pattern layer 12, and an outer lens 13, the pattern layer 12 is disposed on the inner lens 11, and the outer lens 13 is disposed on the inner lens 11; wherein the pattern layer 12 is located between the inner lens 11 and the outer lens 13, and the pupil measuring assembly 2 is arranged on the pattern layer 12.

In order to reduce the interference of the pupil measuring assembly 2 on the vision of the patient, the pupil measuring alignment ring 22 and the scale 21 are outlined by fine lines, and therefore, the images of the pupil measuring alignment ring 22 and the scale 21 are easily blurred due to friction. The positioning of the pattern layer 12 between the inner lens 11 and the outer lens 13 protects the pupil measuring alignment ring 22 and the image-text of the scale 21 on top of the pattern layer 12.

Further, as shown in fig. 4, the outer lens 13 is provided at its periphery with a connection ring 131, and the outer lens 13 is fixedly connected to the inner lens 11 through the connection ring 131, so that a cavity 14 is formed between the inner lens 11 and the outer lens 13.

It will be appreciated that the cavity 14 formed between the inner lens 11 and the outer lens 13 may accommodate the patterned layer 12.

Further, the pattern layer 12 is located in the cavity 14, and either one of the inner lens 11 and the outer lens 13 is fixedly connected with the pattern layer 12.

The pattern layer 12 is fixedly connected to the inner lens 11 or the outer lens 13 through OCA optical cement. Wherein, OCA (Optically Clear Adhesive) optical cement is used for cementing special adhesives of transparent optical elements (such as lenses and the like). The adhesive is required to be colorless and transparent, has light transmittance of more than 95%, good cementing strength, can be cured at room temperature or medium temperature, and has the characteristics of small curing shrinkage and the like.

Further, as shown in fig. 4, the inner lens 11, the pattern layer 12 and the outer lens 13 are all lens structures without optical refraction.

In order to make the patient comfortable, the surface of the entire pupil mirror needs to be smooth, and no obvious protrusion or depression can be formed. In order to match the radian of the eyeball of the human body, the pupil mirror is made into a discoid structure similar to common contact lenses and pupils. Therefore, both the front and back sides of the pupillary mirror must have a smooth curvature. In this embodiment, only the size data of the through hole of the patient is required to be obtained, the pupil mirror is not required to have the function of adjusting the vision degree of the patient, and the inner lens 11, the pattern layer 12 and the outer lens 13 are required to be set into a lens structure without optical refraction. Therefore, a gap is required between the inner lens 11 and the outer lens 13, so that the inner lens 11, the pattern layer 12 and the outer lens 13 maintain a lens structure without optical refraction, and the overall arc smoothness of the pupillary lens can be ensured.

Further, the outer lens 13 is made of a polyester fiber material and the inner lens 11 is made of a silicone hydrogel.

The polyester fiber material has a hard texture, and the outer lens 13 can be kept in the shape of the structure. The silicon hydrogel feet are soft, so that the inner lens 11 can be better attached to the eyeball.

Further, the pupil measuring alignment collar 22 is of various sizes between 1-8 mm in diameter.

Further, the diameters of the pupil measuring alignment rings 22 are sequentially increased by taking 1 millimeter as a difference.

In other embodiments, the diameter of the pupillary measurement alignment collar 22 is sequentially incremented by the difference in size values.

Further, a plurality of scale marks 211 and a plurality of digital marks 212 are arranged on the scale 21, and the scale 21 extends along the direction of increasing the diameter of the pupil measurement alignment ring 22.

Further, either one of the numerical mark 212 and the scale mark 211 corresponds to the pupil measurement alignment ring 22.
