INTEGRATED DEVICE FOR DIAGNOSTIC PURPOSES
First Claim
18. A device for obtaining and analyzing a body fluid sample, comprising:
- a housing;
a lancet body movably disposed in the housing, the lancet body defining a lancet having a tip;
a motor;
a mechanical energy store coupled to the motor, wherein energy from the motor is transferred to and stored by the mechanical energy store, the mechanical energy store being configured to release the stored energy to move the lancet body in a puncturing motion; and
an auxiliary functional component coupled to the motor, wherein additional energy from the motor is transferred to and used by the auxiliary functional component.

Abstract
The present invention provides an integrated measuring device that includes a blood collection system for collecting blood for diagnostic purposes. The blood collection system comprises an electric motor which provides energy for propelling a lancet. The blood collection system comprises a mechanical energy store in which the electric energy that is converted by the motor is stored in the form of mechanical energy. The use of a mechanical energy store allows the use of known mechanical drive elements. The blood collection system can also be electrically activated and is thus easy to use for the operator. The motor can also be coupled to another system component, such as a test strip or lancet drum, to operate it.
