Abstract
The utility model discloses an electrocardiogram measuring ruler, which comprises a divider. The utility model is characterized in that the divider comprises two measuring jaws that are respectively fixed on a main ruler plate and a movable ruler body, wherein, the main ruler plate is provided with voltage scale lines, time scale lines and heart rate scale lines, and the movable ruler is provided with voltage and time subordinate scale lines. Voltage and time values of an electrocardiogram, which is measured by the measuring ruler can respectively reach the accuracy of 0.002 millivolts and 0.001 second, which is increased by 40 to 50 times than the original measuring techniques.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of survey tool of measuring the electrocardiogram related data.
The related data that electrocardiogram is traced is an important evidence of determining cardiac function and disease.Be Electrocardiographic relevant distance value to be measured to Electrocardiographic measurement clinically, find correspondent voltage value, time value according to the distance value of measuring by the numerical table of special use then, perhaps by calculating these parameters by a divider.Because electrocardiogram is that to trace be that precision is low on the scale paper of unit with the millimeter, needing after the measurement to table look-up or calculating just to draw correlation values, and efficient is low, and is not directly perceived.
It is high and do not need to table look-up or calculate and directly measure the electrocardio measuring and calculating chi of related data that the purpose of this utility model provides a kind of certainty of measurement.
Task of the present utility model is to realize like this, this electrocardio measuring and calculating chi, it comprises a divider, it is characterized in that: divider is the individual measuring jaw that is separately fixed on main scale plate and the adjustable rule body, main scale is a stripe board, two graduation marks are arranged in its surface, top is that a longitudinally uniform spacing is 1 millimeter a voltage calibration line, the bottom is that a longitudinally uniform spacing is 1 millimeter a time scale line, the adjustable rule that is enclosed within on the main scale plate is a special-shaped slot cross-section body, the back side with the main scale plate, the two edges part on two sides and the surface that is provided with graduation mark contains, with the corresponding adjustable rule of main scale plate voltage calibration line surface on to be provided with longitudinally uniform spacing be 50 voltage subscale marks of 0.98 millimeter, with the corresponding adjustable rule of main scale plate time scale line surface on to be provided with longitudinally uniform spacing be 40 time subscale marks of 0.975 millimeter.
This utility model is owing to adopted the principle of vernier cursor, and its measuring accuracy has reached 0.02 millimeter, compares with existing 1 millimeter precision, and precision has improved 40-50 doubly, and can directly draw measured voltage, time and heart rate numerical value, measures the efficient height.
Fig. 1 is electrocardio measuring and calculating chi structural representation.

Fig. 3 is a main scale plate time scale line chart.
Fig. 4 is a main scale plate heart rate scale line chart.
Drawing explanation: 1. measuring jaw 2. screws 3. main scale plates 4. voltage subscale marks 5. trip bolts 6. adjustable rule bodies 7. voltage calibration lines 8. heart rate graduation marks 9. time scale lines 10. time subscale mark
In conjunction with above accompanying drawing embodiment of the present utility model is elaborated.
The left end of main scale plate 3 is fixed a measuring jaw 1 with screw 2, another measuring jaw 1 usefulness screw 2 is fixed on the left end of adjustable rule body 6 bottoms, the surface of main scale plate 3 is provided with two graduation marks, top is that a longitudinally uniform spacing is 1 millimeter a voltage calibration line 7, and the bottom is that a longitudinally uniform spacing is 1 millimeter a time scale line 9; The adjustable rule 6 that is enclosed within on the main scale plate 3 is a special-shaped slot cross-section body, the back side, the two sides of main scale plate 3 and the two edges part that is provided with the surface of graduation mark are contained, with the surface of main scale plate voltage calibration line 7 corresponding adjustable rule bodies 6 on to be provided with spacing be 50 voltage subscale marks 4 of 0.98 millimeter, with the surface of the corresponding adjustable rule body of main scale plate time scale line on to be provided with longitudinally uniform spacing be 40 time subscale marks 10 of 0.975 millimeter.Also heart rate graduation mark 8 can be engraved between the voltage calibration line and time scale line on main scale plate 3 surfaces, the distance of each graduation mark of heart rate graduation mark 7 and " 0 " line is 120 ÷ hearts rate (inferior/minute) ÷ 0.04 (millimeter).Heart rate and R-R interval synopsis can also be located on the back side of main scale plate 3 or on the surface between voltage calibration line and the time scale line.The unit of the voltage calibration line of main scale plate 3 is (millivolt), and the unit of time scale line is (second), and the unit of heart rate graduation mark is (inferior/minute).Have a screwed hole and screw 5 to match on the side on adjustable rule body 3 tops, a projection is established in its underpart, is convenient to hands and stirs the adjustable rule body and move.The measuring method of electrocardio measuring and calculating chi is, the adjustable rule body of measuring and calculating chi is moved right, make two measuring jaw tips aim at measured line segment respectively, at this moment, distance between two measuring jaws is the distance of required measurement line segment, its corresponding electrocardio numerical value can directly be read on the relevant graduation mark of measuring and calculating chi, during as measuring voltage, " 0 " graduation mark of the voltage subscale mark of adjustable rule distance of voltage graduation mark " 0 " line on the main scale plate is measured distance value, the integer part of pairing magnitude of voltage is, the whole graduation mark number of the main scale graduation mark in voltage subscale mark " 0 " line left side multiply by the magnitude of voltage (0.1 millivolt) of each graduation mark, and its fractional part is by taking advantage of each subscale mark magnitude of voltage (0.002 millivolt) at interval with the aligned graduation mark of main scale graduation mark apart from the space-number of subscale mark " 0 " line in the subscale mark.The method of measuring Electrocardiographic time value and heart rate is identical with said method, and wherein the every scale of main scale time scale value is 0.04 second, and the every scale of secondary rule is 0.001 second; On the heart rate graduation mark directly target numerical value be the heart rate surveyed (inferior/minute).
