The computational length that the PICC sets pipe is specially length of first rasceta to PICC catheter tip, subtracts the length in clinical use
The first rasceta is gone to set length of tube to the distance of point of puncture to get to clinic PICC.
In the present embodiment, since innermost circle central metering 1 circumference of disk is limited, to meet intuitively 50g scale division value
The demand of calibration, what will necessarily be demarcated is very close, is not easy on rapid consulting ruler intuitively obtain neonatal exact weight.Cause
This sets the demand of pipe according to difference, marks off main interval range on the basis of central metering disk 1 in the present invention,
Then the scale division value calibration line 7 of characterization neonatal weight, point of the scale division value calibration line 5 delimited on the inner ring of metering annulus 6
Angle value is determined as 50g, since the range of circumference becomes larger, even the scale division value of 50g can also fast and accurately obtain its
Position on rapid consulting ruler, so that drawbacks described above is overcome, to meet the needs of in different comparison precision.Area is quickly obtained to realize
Between, the accurate purpose for obtaining length, it is more practical.
As the preferred of present embodiment, the central metering disk 1, indexing annulus 4 and metering annulus 6 are anti-by PE
Shield 8 is fixed, and the driving lever 3 is located between central metering disk 1 and PE shield 8, is protected, and improves practicability
And protective capacities, the length of the driving lever 3 are greater than the center of circle of central metering disk 1 to the metering outer peripheral distance of annulus 6, and
3 end of driving lever, which is fixedly installed with, stirs button 9, convenient for stirring and comparing.
In addition, as shown in Fig. 2, the present invention provides the calculation methods that a kind of newborn sets length of tube rapid consulting ruler, including such as
Lower step:

Comparison calculates, to obtain each length for setting pipe, internal diameter and model, but in actual operation due to task weight,
It is pressed for time, prolonged intensive work makes medical staff be difficult fast and accurately to obtain from numerous tables accordingly
Parameter, which results in low efficiencys, easy the problems such as malfunctioning in actual mechanical process；
The second, by this way, it is only necessary to an individual weight is demarcated, it can be quickly through the mode stirred in the same system
In fast and accurately obtain parameters (different length section have different color identifiers), so as to avoid medical staff
It needs to check table or the tables of data of multiple and different specifications to compare and obtain corresponding parameter, has simply, fast and accurately
Advantage is suitble to be chronically at high-intensitive, nervous grass-roots work, and parameters are not limited to institute in the present embodiment
Put forward, as long as parameter relevant with weight can be corresponding by system (the calculation method or rapid consulting ruler) acquisition
As a result, having stronger scalability.
In the present embodiment, in order to more intuitive by neonatal weight and trachea cannula catheter length, trachea cannula
Relationship between catheter diameter, umbilical vein catheterization depth and umbilical vein model accurately embodies, by the pass between them
System is directly projected on indexing annulus 4, so that the relationship between them is intuitively obtained, the indexing on different indexing annulus 4
Described in following four tables of relationship between line 5:

In the present embodiment, PICC sets length of tube and can be selected according to above-mentioned, and converts in advance, due to
It is linear relationship, different is only the scale value difference in gauging calibration line 10, and other all the same, m is indexing
It is worth the numerical value of calibration line 7, that is, sets pipe same day neonatal weight, unit kg.Neonatal weight will be corresponded to according to scale division value
For 50g relationship calibration on the inner ring of metering annulus 6, and by its first rasceta corresponding with weight to PICC catheter tip
Calibrating length on the outer ring of metering annulus 6 so that simple, quicklook can be obtained when stirring driving lever 3
Obtain their corresponding relationship and accurate numerical value.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
