Injection device
First Claim
1. An injection device for the injection into a patient of a medical agent contained within a vial, comprising:
- a housing;
a compartment configured to receive the vial;
a needle that is movable in a first direction in order to puncture the patient; and
a pressing member configured to force the medical agent from the vial and through the needle into the patient;
wherein the needle is movable from an initial position in accordance with a first motion profile in which the needle moves a first distance relative to the housing followed by a rest period, and in accordance with a second motion profile in which the needle is returned to the initial position without a rest period after moving relative to the housing to puncture the patient.

Abstract
The invention refers to an injection device for the injection of a medical agent, in particular insulin, comprising: a housing, a reception compartment for a vial containing the agent to be injected, advancement mechanics for moving an injection needle that is inserted in the device in a direction of puncturing, and a pressing facility for pressing agent from a vial that is inserted in the reception compartment for the purpose of an injection process. The advancement mechanics, effects, in a first device function for an injection process, a first motion profile of an inserted injection needle, in which a resting phase follows after an advancement motion, during which resting phase the inserted injection needle for an injection process is at rest with respect to the device housing, and effects, in a second device function for obtaining a body fluid sample for diagnostic purposes, a second motion profile of an inserted injection needle, in which a returning motion follows immediately after a puncturing motion.
