Description
Technical field
The present invention relates to a kind of medical survey tool, the particularly one direct-reading adjusting zero ekg strip wing divider of exempting to convert.
Background technology
Electrocardiographic caliper is for measuring Electrocardiographic medical instrument, having a kind of is ECG rule (CN92300754.7), its operation principle is with after the instrument intercepted lengths such as compasses, converse electrocardiogram numerical value according to length control electrocardiogram chi again, this measuring method is more loaded down with trivial details, and has reduced operating efficiency. Also having one is electrocardiographic caliper, and the patent No.: CN201220029471.1 is provided with rule on divider, from slide ruler, can directly read the distance between two needle points, be the equal of compasses that have radius scale, although this divider improve to some extent,, still there is certain defect, 1, it does not have zeroing function, in use, if when needle point distance is inconsistent with graduation indication, because can not return to zero, will cause error. 2, on its rule, only has a line scale, its expression be the length distance between two needle points, when measurement, need first according to reading the length distance between two needle points, utilize ECG rule to converse time span corresponding to this length distance and voltage readings, can not be from the rule of divider directly readout time span and voltage readings scaled value, it is very inconvenient to use. 3, when reading, the visual angle of rule and two eyes is stravismus angle, and eyes are not easy identification, easily occur mistake and error.
Summary of the invention
The technical problem that the present invention solves is, overcomes the deficiency of background technology, and a kind of simple in structure, easy to use exempting from direct-reading adjusting zero ekg strip wing divider that converts is provided.
Technical scheme of the present invention is: the one direct-reading adjusting zero ekg strip wing divider of exempting to convert, left needle point is set on arm parting rule on the left side, right needle point is set on arm parting rule on the right side, arc chi dish is set on arm parting rule on the left side, it is characterized in that: the adjustable left needle point of the degree of depth is set on arm parting rule on the left side, the adjustable right needle point of the degree of depth is set on arm parting rule on the right side, parting on the right side between rule arm and right needle point, parting between rule arm and left needle point setting respectively on the left side and screw and turn round, left needle point and right needle point are bent downwardly respectively 45 degree, right needle point 15 degree that slope inwardly again on the basis that is bent downwardly 45 degree; At the inner side of arc chi dish setup times scale, at the arranged outside voltage calibration of arc chi dish, bidirectional pointer is set on arm parting rule on the right side.
Before the described direct-reading adjusting zero ekg strip wing divider that converts of exempting from, it is characterized in that: bidirectional pointer assumes diamond in shape, it is arranged on the centre of time scale and voltage calibration.
The aforesaid direct-reading adjusting zero ekg strip wing divider of exempting to convert, is characterized in that: the scale numeral longitudinal arrangement of time scale, the scale numeral of voltage calibration is transversely arranged.
The aforesaid direct-reading adjusting zero ekg strip wing divider of exempting to convert, is characterized in that: when the distance between left needle point and right needle point is 25mm, the scale that time scale is corresponding is 1 second, and the scale that voltage calibration is corresponding is 2.5mV.
When use, first left needle point and right needle point are closed up, whether the reading of seeing arc chi dish is " 0 ", if be not " 0 ", first unclamp to part rule arm on the left side and part screwing on rule arm on the right side and turn round, rotate left needle point and right needle point, or adjust left needle point and the right needle point cooperation degree of depth on divider arm, when right needle point and left needle point are closed up, the voltage calibration in the time scale of arc chi dish inner side and arc chi dish outside is just in time " 0 ", when measurement, the electrocardiograph paper that two tip alignment will be surveyed, distance on drawing between horizontal two needle points represents time span, fore-and-aft distance between two needle points represents voltage, in the time that lateral separation on drawing is 25mm, the time scale of arc chi dish inner side is just in time designated as 1, represent in the time that the chart drive speed of electrocardiograph paper is 25mm/ second, the time span of 1 second, when distance on drawing between longitudinal two needle points is 25mm, the voltage calibration instruction 2.5 in arc chi dish outside, when the calibration voltage on expression electrocardiogram is 10mV, the voltage readings on electrocardiograph paper is 2.5mV, the relation of other reading and distance is by that analogy. downward-sloping 45 degree of left needle point and right needle point, can make eyes mutually vertical with yardstick dish, are convenient to observed reading while making to measure, the scale numeral longitudinal arrangement of time scale, the scale numeral of voltage calibration is transversely arranged, does not need the divider that overturns, and can directly read scale.
The invention has the beneficial effects as follows: 1, be provided with needle point zeroing function and the needle point degree of depth and adjust function, alignment error at any time, makes to measure more accurate. 2, from arc chi dish, can directly read time span and magnitude of voltage, not need to convert, easy to use. 3, when reading, rule is vertical with the visual angle of two eyes, and easily identification, is not prone to mistake and error.
