APPARATUS AND METHOD FOR MEASURING DOSE IN INJECTOR
First Claim
1. An apparatus for measuring a dose in an injector, comprising:
- a number sleeve that passes through an injector body and is connected to the injector body to be spirally movable, a pattern for dose measurement being formed on an outer periphery of the number sleeve; and
the injector body comprising;
a sensor for sensing the pattern formed on the number sleeve when the number sleeve performs a spiral movement; and
a controller for measuring a dose according to a spiral movement distance of the number sleeve through the sensor.

Abstract
Provided is an apparatus and method for measuring a dose in an injector, which is capable of measuring a dose without modifying the mechanical structure of the injector. A number sleeve is provided to pass through an injector body and is connected to be spirally movable, and a pattern for dose measurement is formed on an outer periphery of the number sleeve. The injector body includes a sensor for sensing the pattern formed on the number sleeve when the number sleeve performs a spiral movement, and a controller for measuring a dose according to a spiral movement distance of the number sleeve through the sensor.

10. A method for measuring a dose in an injector, the injector including a number sleeve passing through an injector body and having a pattern on an outer periphery thereof in a spiral direction, and the injector body having a sensor for sensing a change in the pattern formed on the number sleeve, the method comprising:
-
sensing the change in the pattern formed on the number sleeve when the number sleeve performs a spiral movement while passing through the injector body; measuring a spiral movement distance of the number sleeve according to the change in the pattern; and measuring a dose according to the measured spiral movement distance. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
