Abstract

The utility model discloses a high-precision pupillometry rule. Semicircular pupil comparison marks with different sizes are arranged on the edge of a rectangular rule plate, and corresponding digital size symbols are arranged near the semicircular pupil comparison marks. The high-precision pupillometry rule is simple in structure, convenient to use, low in cost, capable of directly reading digitals during measuring, and beneficial to accurate measurement. The high-precision pupillometry rule is specially used by a specially assigned person, and avoids cross using, so that the danger of infection in a hospital is reduced.

Description

High accuracy pupillometry chi

Technical field

This utility model relates to a kind of clinical tool using, relates in particular to a kind of high accuracy pupillometry chi.

Background technology

The change of pupil is one of vital sign of reflection nervous system disease, is the important evidence that medical personnel judge the state of an illness.All to carry out the observation and the measurement of pupil clinically to critical patient, particularly to neural training patient.At present use ocular estimate to estimate the size of pupil clinically usually, this method is because no object of reference, and the influence of subjective judgment between the tested person person, the very big difference of existence between the measurement result; Groups of people measure with the self-control measuring device, though accuracy promote to some extent because the inconvenience of using is not widely adopted; Though and up-to-date pupillometry instrument has higher precision, because of price height, cleaning-sterilizing are difficult for also extensively not adopting.

The utility model content

The purpose of this utility model be to provide a kind of simple in structure, easy to use, but cost is low, direct reading when measuring, and helps the high accuracy pupillometry chi of accurately measuring.

To achieve these goals, the technical solution of the utility model is: a kind of high accuracy pupillometry chi is provided, wherein, be provided with the semicircle pupil contrast marker of different size at the edge of rectangle chi plate, the digital symbol for dimensioning that correspondence nearby all is set of described each semicircle pupil contrast marker.

But this utility model high accuracy pupillometry chi is simple in structure, easy to use, cost is low, direct reading when measuring, and helps accurate measurement; Special messenger's special use is avoided intersecting and is used, and reduces the danger of nosocomial infection.

Description of drawings

Fig. 1 is the structural representation of this utility model high accuracy pupillometry chi;

Among the figure: 1, semicircle pupil contrast marker; 2, rectangle chi plate; 3, semicircle pupil contrast marker; 4, digital symbol for dimensioning.

The specific embodiment

For the technology contents, the structural feature that describe this utility model high accuracy pupillometry chi in detail, be described further below in conjunction with embodiment and conjunction with figs..

As shown in Figure 1, this utility model high accuracy pupillometry chi, be provided with the semicircle

pupil contrast marker

1 or 3 of different size successively by size at the upper and lower edge of rectangle chi plate 2, the digital symbol for dimensioning 4 that correspondence nearby all is set of described each semicircle pupil contrast marker 1.

Semicircle

pupil contrast marker

1 or 3 usefulness black backgrounds set off, and demarcate effective unit with the black printed words, and with semicircle pupil contrast marker sequence arrangement by size; Four angles of rectangle chi plate are set to circular arc, improve its safety.

The using method of this utility model high accuracy pupillometry chi:

The gauger stands in the patient left side, and left hand food, middle finger are separately gone up palpebra inferior, and left hand thumb and middle finger are held dip stick, near eyelid, the semicircle pupil contrast marker of dip stick is visually overlapped with patient's pupil; The right hand is held the 3V concentration torch, and light source is adjusted to correct position apart from pupil 3-5cm irradiation with dip stick, and gauger's optical range pupil 33cm(is about an arm distance), reading; With record behind the quadrat method measurement offside.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of this utility model certainly with this, and therefore the equivalent variations of being done according to this utility model claim still belongs to the scope that this utility model is contained.

Claims

1. high accuracy pupillometry chi is characterized in that: be provided with the semicircle pupil contrast marker of different size at the edge of rectangle chi plate, the digital symbol for dimensioning that correspondence nearby all is set of described each semicircle pupil contrast marker.
