Embodiment Construction

[0026] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0027] The invention discloses a pupil diameter measuring device, which can continuously measure the pupil diameter, and can perform light reflection inspection. The device is based on the principle of optical imaging (light travels in a straight line in the same medium), and largely solves the problem that the current device for measuring the pupil diameter cannot continuously, dynamically and accurately measure the pupil diameter.

[0028] The pupil diameter measuring device comprises a pupil measuring part 1 and a hand-held part 2, figure 1 , figure 2 and image 3 They are schematic diagrams of the structure of the pupil diameter measuring device under different viewing angles. The pupil measuring unit 1 includes a ring bracket 101 and a ring alignment device 102 embedded in the ring bracket 101 . The inner diameter of the annular suppo...

Abstract

The invention provides a pupil diameter measuring device and belongs to the technical field of measurement. The pupil diameter measuring device includes a pupil measuring part and a hand holding part.The pupil measuring part includes an annular alignment device; an inner ring of the annular alignment device is variable in diameter and used for aligning a pupil of a to-be-measured person, and thediameter of the pupil of the to-be-measured person is determined by the diameter of the inner ring. The hand holding part is connected to the pupil measuring part and used for allowing a user to holda pupil diameter measuring device body. The pupil diameter measuring device is a simple device capable of continuously and accurately measuring the pupil diameter and capable of detecting light reflection; the operation is simple, the learning cost is extremely low, and the device is very suitable for being used by front-line clinical workers in the emergency department, the neurology department,the neurosurgery department, the ophthalmology department, intensive care units and the like.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a measuring device, in particular to a pupil diameter measuring device. Background technique [0002] The devices currently used to measure pupil diameter can be divided into two categories: rulers with multiple observation holes of different diameters and circular patterns of different diameters. These two methods are commonly used, easy to operate and easy to carry. Their discontinuity and simple comparison with visual inspection are likely to cause large errors. Different measurers or the same measurer have large errors in multiple measurements of the same patient. The accuracy of measuring pupil diameter and Consistency is poor. Therefore, there is an urgent clinical need for a simple device that can continuously and dynamically measure the diameter of the pupil. Contents of the invention [0003] The purpose of the present invention is to provide a simple device capabl...
