Abstract
The utility model discloses an electrocardiogram measuring protractor, which comprises two protractor arms hinged together at end portions, an arc-shaped graduated board is fixedly mounted on the inner side of one protractor arm, center of the arc-shaped graduated board is arranged at the hinged position, a through hole for the graduated board to pass through is arranged on the other protractor arm, heart rate graduation lines and voltage value graduation lines are arranged on the graduated board, the graduated board is further provided with distance graduation lines, the heart rate graduation lines and the voltage value graduation lines are arranged on a same vertical face of the graduated board, the distance graduation lines are arranged on the other vertical face of the graduated board, the two protractor arms are a left protractor arm and a right protractor arm, the graduated board is mounted on the left protractor arm, and a bolt positioning the graduated board and the right protractor arm is arranged on the right protractor arm. The electrocardiogram measuring protractor has the advantages of high working efficiency, intuition and accuracy.
Description
Technical field
This utility model relates to a kind of medical measuring apparatus, specifically is a kind of measurement divider that is used to measure the electrocardiogram correlation values.
Background technology
The related data that electrocardiogram is traced is an important evidence of determining cardiac function and disease.Way to ecg measurement is to use divider that Electrocardiographic relevant distance value is measured clinically, this divider comprises the two rule arms that the end is hinged, the aciculiform measuring jaw is equipped with in the lower end of rule arm, measuring jaw is aimed at two measurement points on the electrocardiogram, at the distance value of measuring by ruler between two measuring jaws, find corresponding heart rate number, magnitude of voltage and time value etc. according to the gained distance value by calculating or special-purpose numerical table then.This measuring method need be used multiple instruments such as ruler, divider, need table look-up or calculate after the measurement just to draw correlation values, thereby inefficiency, and is not directly perceived, and measure between two measuring jaws apart from the time precision not high, be easy to generate error.
The utility model content
The technical problems to be solved in the utility model provides a kind of ecg measurement divider that can intuitively read related data on the electrocardiogram.
For addressing the above problem, the ecg measurement divider that is provided comprises two rule arms that the end is hinged, its construction features is: wherein the inboard of a rule arm is fixed with curved graduated tile, the center of circle of this graduated arc is positioned at the hinged place, another rule arm is provided with the through hole that passes for graduated tile, and graduated tile is provided with heart rate and counts graduation mark and magnitude of voltage graduation mark.
After adopting said structure, when Electrocardiographic related data is measured, open two rule arms and make two measurement points on its lower end aligned electrocardiogram, it is to engrave after as calculated according to the conversion relation of related data on the electrocardiogram that heart rate on the graduated tile is counted graduation mark and magnitude of voltage graduation mark, can read heart rate number and the magnitude of voltage on two measurement points on the electrocardiogram accurately according to the position on the rule arm graduated tile of living in, no longer need to table look-up or calculate.Thereby the utlity model has high efficiency, visual and accurate advantage.
As improvement of the present utility model, also be provided with the distance scale line on the graduated tile, heart rate counts graduation mark and the magnitude of voltage graduation mark is arranged on the same facade of graduated tile, the distance scale line is arranged on another facade of graduated tile, can on same facade, read heart rate number and magnitude of voltage intuitively, need further accurately to measure or when confirming, can calculate running into, draw required numerical value by the distance value of reading on another facade.
As further improvement of the utility model, two rule arms are respectively left side rule arm and right rule arm, graduated tile is installed on the rule arm of a left side, also be bolted with on the right rule arm graduated tile and the localized bolt of right rule arm, behind two measurement points on the two rule arm lower end aligned electrocardiograms, can arm and graduated tile location be advised in the right side, see the numerical value on the graduated tile again by bolt, because of the operating error that reason causes such as rocking, further improved accuracy of measurement when having avoided like this because of manual operation.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sketch map of Fig. 1 backsight;
Fig. 3 be among Fig. 1 A to sketch map.
The specific embodiment
As Fig. 1, ecg measurement divider shown in Fig. 2 and Fig. 3, it comprises two rule arms 1 that the end is hinged, two rule arms 1 are respectively left side rule arm and right rule arm, the top of hinged place is provided with handle 2, the bottom of left side rule arm and right rule arm respectively is fixed with the aciculiform measuring jaw, the inboard of left side rule arm is fixed with curved graduated tile 3, the center of circle of this graduated arc 3 is being positioned at the hinged place, right rule arm is provided with the through hole 4 that passes for graduated tile 3, also be bolted with on the right rule arm graduated tile 3 and the localized bolt 5 of right rule arm, graduated tile 3 is provided with the distance scale line, heart rate is counted graduation mark and magnitude of voltage graduation mark, heart rate counts graduation mark and the magnitude of voltage graduation mark is arranged on the same facade of graduated tile 3, the distance scale line is arranged on another facade of graduated tile 3, B place shown in Fig. 1 is that heart rate is counted graduation mark, the C place is the magnitude of voltage graduation mark, and the D place is the distance scale line among Fig. 2.
