Description
Technical field
This utility model relates to a kind of medical survey tool, particularly one and exempts from the direct-reading adjusting zero electrocardiogram winged divider that converts.
Background technology
Electrocardiographic caliper is used to measure Electrocardiographic medical instrument, have a kind of for ECG rule (CN92300754.7), its operation principle is with after the instrument intercepted lengths such as compasses, electrocardiogram numerical value is conversed further according to length control electrocardiogram chi, this measuring method is comparatively laborious, and reduces work efficiency.Also having one is electrocardiographic caliper, and the patent No.: CN201220029471.1 is provided with rule on divider, the distance between two needle points can be directly read from slide rule, be the equal of the compasses having radius scale, although this divider improves to some extent, but, still there is certain defect, 1, it does not has zeroing function, in use, if needle point distance is inconsistent with graduation indication, because can not return to zero, may result in error.2, only has a line scale on its rule, what it represented is the length distance between two needle points, during measurement, need first according to the length distance read between two needle points, ECG rule is utilized to converse time span corresponding to this length distance and voltage readings, can not from the rule of divider span and the scaled value of voltage readings direct readout time, it is the most inconvenient to use.3, during reading, the visual angle of rule and two eyes is stravismus angle, and eyes are not easy to identify, mistake and error easily occur.
Summary of the invention
This utility model solves the technical problem that and is, overcomes the deficiency of background technology, it is provided that a kind of simple in construction, easy to use exempt from the direct-reading adjusting zero electrocardiogram winged divider that converts.
The technical solution of the utility model is: one exempts from the direct-reading adjusting zero electrocardiogram winged divider that converts, parting on the left side, on rule arm, left needle point is set, parting on the right side, on rule arm, right needle point is set, parting on the left side, on rule arm, arc chi dish is set, it is characterized in that: parting the left needle point that depth adjustable is set on rule arm on the left side, parting the right needle point that depth adjustable is set on rule arm on the right side, parting on the right side between rule arm and right needle point, torsion is screwed parting on the left side to be respectively provided with between rule arm and left needle point, left needle point and right needle point bend 45 degree separately down, right needle point slopes inwardly again 15 degree on the basis of being bent downwardly 45 degree；Time scale is set in the inner side of arc chi dish, voltage calibration is set in the outside of arc chi dish, parting on the right side, on rule arm, bidirectional pointer is set.
Before described exempt from the direct-reading adjusting zero electrocardiogram winged divider that converts, it is characterized in that: bidirectional pointer assumes diamond in shape, it is arranged on the centre of time scale and voltage calibration.
Aforesaid exempt from convert direct-reading adjusting zero electrocardiogram winged divider, it is characterized in that: the scale numeral longitudinal arrangement of time scale, the scale numeral of voltage calibration is transversely arranged.
Aforesaid exempt from convert direct-reading adjusting zero electrocardiogram winged divider, it 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.
During use, first left needle point and right needle point are closed up, whether the reading seeing arc chi dish is " 0 ", if not being " 0 ", first unclamp part on the left side rule arm and part on the right side rule arm on screw torsion, 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 making right needle point and left needle point close up, time scale inside arc chi dish and the voltage calibration outside arc chi dish are just " 0 ", during measurement, by electrocardiograph paper to be surveyed for two tip alignment, distance express time span between horizontal two needle points on drawing, fore-and-aft distance between two needle points represents voltage, when on drawing, lateral separation is 25mm, time scale inside arc chi dish is just designated as 1, represent when the chart drive speed of electrocardiograph paper is 25mm/ second, the time span of 1 second；When on drawing, longitudinally distance between two needle points is 25mm, the voltage calibration instruction 2.5 outside arc chi dish, represent that when the calibration voltage on electrocardiogram is 10mV, the voltage readings on electrocardiograph paper is 2.5 mV, the relation of other reading and distance is by that analogy.Left needle point and downward-sloping 45 degree of right needle point, can make eyes be mutually perpendicular to yardstick dish, make to be easy to during measurement observed reading, the scale numeral longitudinal arrangement of time scale, and the scale numeral of voltage calibration is transversely arranged, it is not necessary to upset divider, it is possible to directly read scale.
The beneficial effects of the utility model are: 1, be provided with needle point zeroing function and the needle point degree of depth and adjust function, can alignment error at any time, make measurement more accurate.2, time span and magnitude of voltage can be directly read from arc chi dish, it is not necessary to conversion, easy to use.3, during reading, rule and the viewing angles-both vertical of two eyes, easily identify, be difficult to that mistake and error occur.

Detailed description of the invention
In Fig. 1, Fig. 2, parting on the left side, on rule arm 1, left needle point 2 is set, parting on the right side, on rule arm 3, right needle point 4 is set, parting on the left side, on rule arm 1, arc chi dish 5 is set, it is characterized in that: parting the left needle point 2 that depth adjustable is set on rule arm 1 on the left side, parting the right needle point 4 that depth adjustable is set on rule arm 3 on the right side, it is respectively provided with parting on the right side between rule arm 3 and right needle point 4, parting on the left side and screws torsion 8 between rule arm 1 and left needle point 2, left needle point 2 and right needle point 4 bend 45 degree separately down, and right needle point 4 slopes inwardly again 15 degree on the basis of being bent downwardly 45 degree；Time scale 6 is set in the inner side of arc chi dish 5, voltage calibration 7 is set in the outside of arc chi dish 5, parting on the right side, on rule arm 3, bidirectional pointer 9 is set.
Bidirectional pointer 9 assumes diamond in shape, and it is arranged on time scale 6 and the centre of voltage calibration 7.
The scale numeral longitudinal arrangement of time scale 6, the scale numeral of voltage calibration 7 is transversely arranged.
When distance between left needle point 2 and right needle point 4 is 25mm, the scale of time scale 6 correspondence is 1 second, and the scale of voltage calibration 7 correspondence is 2.5mV, and other corresponding relation is by that analogy.
