Puncturing system, lancet reservoir system and manufacturing method, and method for positioning functional elements on carrier tape

摘要

A puncturing system includes a carrier tape carrying multiple lancets and having position marks, a housing comprising a conveying facility for positioning the lancets and a housing opening, a puncturing drive for accelerating a lancet positioned in a usage position, a storage medium for storing distance values that depend on distances between the lancets of the carrier tape and position marks allocated to the respective lancets, a sensor for detecting position marks in a detection position through which the position marks proceed upon motion of the carrier tape, and a control unit that controls the conveying facility. To position a lancet in the usage position, the control unit stops the conveying facility upon the carrier tape moving a positioning distance. The length of the positioning distance depends on the distance between the lancet to be positioned and the detected position mark and is determined by the control unit.

主权项

1. A puncturing system comprising:
a carrier tape that comprises multiple lancets and position marks, each lancet being allocated a respective one of the position marks; a storage medium configured to store distance values corresponding to measured distances between specific lancets of the carrier tape and the respective position marks; a device housing that comprises a tape drive for positioning the lancets consecutively in a usage position by moving the carrier tape in a conveying direction and has a housing opening for touching against a body part in which a puncture is to be made by a puncturing motion of the lancet in the usage position; a sensor configured for detecting the position marks; a control unit that is connected to the sensor, the control unit configured to:
(i) cause the tape drive to convey the carrier tape to a tape position in which the respective position mark for one of the lancets is detected by the sensor;(ii) access from the storage medium the distance value for the one lancet; and(iii) cause the tape drive to move the carrier tape in the conveying direction by the distance value for the one lancet, thereby positioning the one lancet in the usage position; and a puncturing drive for accelerating the lancet that is positioned in the usage position for the puncturing motion.
