Abstract

The utility model relates to a portable pupil dynamic measuring device, which belongs to the technical field of the medical examination, and comprises pupil diameter marking holes, a ruler body, scale marks, pupil diameter marking values, a ruler handle, arc-shaped nose brackets, a long side and a short side. The portable pupil dynamic measuring device is characterized in that 16 pupil diameter marking holes are designed on the surface of the ruler body, and are marked with pupil diameter values, so that variation of a critical patient's pupil can be accurately measured; 5 half-round arc-shaped nose brackets with different radiuses are designed in a human orientated way according to widths of the nose bridges of the patients, so that the device can be placed on the nose of the patient for measuring interpupillary distance, inner-canthal distance, outer-canthal distance, and eyelid length. The portable pupil dynamic measuring device is simple to manufacture, has a small volume, is scientifically practical, has low cost and is simple to use.

Description

Portable pupil dynamic measurement device

Technical field

This utility model relates to a kind of medical inspection easy device, belongs to the medical examination technical field.

Background technology

In daily medical nursing work, must carry out comprehensive and careful observation and analysis to patient's the state of an illness, pupil changes the variation of the direct or indirect reaction state of an illness; Especially intracranial disease, patient's pupils such as drug intoxication change comparatively complicated, changeable, are indicating that directly advancing of disease changes and lapses to; So accurately observe the variation of pupil size and pupil shape at any time; For grasping the dynamic state of an illness of the very first time, the life that gives emergency treatment to a patient is striven for the quality time, and diagnosis and treatment are provided important evidence and improve treatment efficient; Hospital lacks special pupil examination equipment mostly; The naked eyes range estimation commonly used of clinical observation pupil, ruler are measured, the method for contrast is come subjective judgment, and not only error is big, free adjustment property is poor, and time-consuming; Influence work efficiency, provide the data that have error directly to influence the diagnosis of doctor's disease and incur loss through delay patient's rehabilitation.

Summary of the invention

This utility model has overcome the shortcoming that with the naked eye estimation error is bigger in the past at 16 PD index aperture of chi body plane design and labelling PD numerical value; Can accurately measure the critical patient pupil changes; Grasp the dynamic state of an illness of the very first time; Improve the accuracy and treatment efficient of disease observation, and chi body one lateral edges according to the human oriented design of patient's bridge of the nose width the semicircle nose holder arc of 5 kinds of different radiis be used for frame and measure the dicoria spacing in patient's nose bridge; That this utility model is made is simple, volume is little, science is practical, with low cost, method for using is simple.

Technical scheme: (can understand) referring to accompanying drawing

A kind of portable pupil dynamic measurement device, its characteristic is made up of PD index aperture, chi body, scale mark, PD tag value, chi handle, nose holder arc, long side edges, short lateral edges.

This utility model technical scheme also comprises described portable pupil dynamic measurement device; It is characterized in that selecting for use rustless steel thin slice or hard transparent plastic material; Two-sided design is identical, and the chi body is provided with 16 the accurate labelling PD of PD index aperture tag value, and in chi body long side edges scale mark is arranged; Nose holder arc is provided with 5 kinds of different radii specifications, and in the short lateral edges single-sided design of chi body for semicircle and be provided with the chi handle and conveniently grasp.

Advantage of this utility model and beneficial effect:

1. that portable pupil dynamic measurement device is made is simple, volume is little, science is practical, with low cost, method for using is simple.

2. portable pupil dynamic measurement device can accurately be measured the critical patient pupil and change, and grasps the dynamic state of an illness of the very first time, and the accuracy that improves disease observation provides important evidence to clinical diagnosis.

Description of drawings:

Accompanying drawing is the portable pupil dynamic measurement device of a this utility model structural representation

Below in conjunction with accompanying drawing the specific embodiment of this utility model is done further explain:

Label among the above-mentioned figure: 1--PD index aperture, 2--chi body, 3--scale mark, 4--PD tag value, 5--chi handle, 6--nose holder arc, 7--long side edges, the short lateral edges of 8--.

The specific embodiment:

This utility model is made up of PD index aperture 1, chi body 2, scale mark 3, PD tag value 4, chi handle 5, nose holder arc 6, long side edges 7, short lateral edges 8.

Operation principle: medical personnel's portable handheld formula pupil dynamic measurement device chi handle 5; Under the available light; But cooperation patient any direction is direct and the contrast of patient's pupil; Aim at pupil find out with PD index aperture 1 under PD tag value 4 accurately measure the sizes of pupils, write down corresponding diameter tag value; The torch that throws light on by medical care personnel is used in the combination of this utility model and pocket lamp under the rather dark situation of comatose patient, and examiner's left hand thumb, first finger draw back eyelid gently, and the right hand is held chi and measured pupil with above-mentioned method.This utility model also according to the human oriented design of patient's bridge of the nose width the semicircle nose holder arc 6 of 5 kinds of different radiis be used for frame and measure dicoria spacing, endocanthion apart from, outer canthus distance in patient's nose bridge, eyelid length etc. can be used as oculistic capable little assistant.
