Abstract
In some embodiments, a device may include a tube having substantially cylindrical body defining an enclosure and having an open end. The tube may include measurement units printed along at least one side. The device may further include a stopper element releasably coupled to the open end of the cylindrical body and configured to selectively engage a needle to mark a length of the needle.
Claims20
A calibration device comprising:
- a tube having a substantially cylindrical body defining an enclosure and having an open end, the tube including measurement units printed along at least one side;
- and
- a slidable element releasably coupled to the open end of the cylindrical body and configured to selectively engage a needle and provide a dynamic measurement on the needle.
A method comprising:
- determining a safe depth parameter for insertion of a needle;
- determining a location on a needle based on measurement units printed on at least one of the needle or a side of a calibration device, the location corresponding to the safe depth parameter;
- and
- marking the needle at the location corresponding to the safe depth parameter.
1 more element
A calibration device comprising:
- a housing;
- an opening extending into the housing and sized to receive a needle;
- calibration marks adjacent to the opening, the calibration marks configured to define a plurality of weight ranges and to define regularly spaced measurement units;
- and
- an element configured to secure the needle to allow marking of the needle to a selected length based on the calibration marks.
