Abstract

The utility model relates to a kind of side illuminated pupil pens, it is made of handwriting and light source, it is characterized by: light source is arranged in the side of handwriting and switchs in the same plane, the back side of light source is milimeter scale and imitation pupil, and imitation pupil diameter is respectively 4 millimeters, 6 millimeters, 8 millimeters.Its is structurally reasonable, and using simple, operator can accurately calculate the size of the diameter of patient s pupil, is required with determining whether patient has reached operation, while can fast and accurately judge the pupil status of patient.

Description

Side illuminated pupil pen

Technical field

The utility model relates to a kind of side illuminated pupil pens, belong to eye examination apparatus.

Background technique

The circular hole in iris center is known as pupil, and pupil can be adjusted into intraocular light, and the size of pupil is with light Strong and weak and changes, its average diameter is 3mm.Mydriasis, which refers to, benumbs ciliary muscle or sphincter pupillae by the stimulation of drug, Expand pupil and in adjusting stationary state.It is the important preparation before the intraocular surgeries such as cataract, the vitreous excision of ophthalmology Work.Intraocular surgery requires pupil diameter to reach 6-8mm, and the big state that dissipates can be maintained in art, optimal pupil in art Diameter answers >=8mm.Nurse is needed constantly to observe the state of mydriasis, during mydriasis to determine whether to have reached operation Requirement.Existing observation method substantially there are two types of: 1, using being surveyed while holding straight illuminated flashlight irradiation pupil with surveying pupil ruler Pupil diameter is measured, drawback is that nurse needs both hands to operate, and takes a long time and the uncomfortable even eyeground of patient is easily caused to be burnt；2, only with hand Straight illuminated flashlight irradiation pupil is held, estimates pupil diameter by rule of thumb, the pupil that drawback is estimated as in millimeters by rule of thumb is straight The obvious accuracy of diameter will substantially reduce, and this small gap can not only be sentenced with naked eyes when especially needing to compare between eyes It is disconnected.

Summary of the invention

Structurally reasonable the purpose of this utility model is to provide a kind of side illuminated pupil pen, using simple, operator can Accurately to calculate the size of the diameter of patient s pupil, required with determining whether patient has reached operation, while can be quickly quasi- The true pupil status for judging patient.

The technical solution of the utility model is achieved in that side illuminated pupil pen, is made of handwriting and light source, feature Be: light source is arranged in the side of handwriting and switchs in the same plane, and the back side of light source is milimeter scale and imitation pupil, simulation Pupil diameter is respectively 4 millimeters, 6 millimeters, 8 millimeters.

The good effect of the utility model be using when light source be pointed into patient's eye, milimeter scale then face operator, therefore Operator can accurately calculate the size of the diameter of patient s pupil, be required with determining whether patient has reached operation, while can Fast and accurately to judge the pupil status of patient, clinical ophthalmology can be not only used for, while being also widely applied to need to observe The associated departments such as the intensive care unit of pupil status and neurology department.

Detailed description of the invention

Fig. 1 is the structure chart of the utility model.

Fig. 2 is the side structure schematic diagram of the utility model.

Specific embodiment

The utility model is further described with reference to the accompanying drawing: as shown in Figure 1, 2, side illuminated pupil pen, by pen Body 1 and light source 2 form, it is characterised in that: handwriting 1 is arranged in light source 2 side and switch 3 in the same plane, the back of light source 1 Face is milimeter scale 4 and imitation pupil 5, and 5 diameter of imitation pupil is respectively 4 millimeters, 6 millimeters, 8 millimeters.

When ophthalmology, intensive care unit and neurology department need to observe patient s pupil's state, light source 1 need to only be shone by lower switch To patient's eye, the then face operator of milimeter scale 4, therefore operator can be according to three 4 millimeters, 6 millis on imitation pupil 5 Rice, 8 millimeters of pupil accurately calculate the size of the diameter of patient s pupil, are required with determining whether patient has reached operation, together When can fast and accurately judge the pupil status of patient, to judge the change of illness state of patient.

Claims

1. side illuminated pupil pen, is made of handwriting and light source, it is characterised in that: the side of handwriting is arranged in switch same in light source In one plane, the back side of light source is milimeter scale and imitation pupil, and imitation pupil diameter is respectively 4 millimeters, 6 millimeters, 8 millimeters.
